GENERAL INFORMATION
CAUTION! Safety first. Be extremely
careful when looking into or putting your hands or any other body part into your
engine compartment. Use safety glasses. Keep all body parts away from open
carburetor or air intake -- assume it will backfire. Backfires can produce
blindness and/or third degree burns. Keep long hair VERY securely pinned up,
remove all jewelry, do not wear loose clothing while working on a car. Heed
these warnings even when the car is not running. Remember, modern cars have
electric fans that can turn on at any time.
Be careful not to short the battery --
battery explosions can throw potentially burning/blinding acid. Don't open the
radiator cap of an overheated car. When it's cool enough to open, use a rag to
block any spray, and open very slowly. Wear hard shoes capable of shielding
impact from a dropped part.
Take proper precautions when jacking
up a car so the jack doesn't "kick out". A "kicked out" jack
can be every bit as destructive as a kick from a large horse. Block the wheels,
put on the brakes, seat the jack properly. Never crawl under a jacked up car
unless it has been properly blocked up and completely secured. Even then,
remember that earthquakes, sudden wind and drunk driver impacts happen. A
professional lift is always best.
The preceding warnings are by no means
an exhaustive list of the risks encountered when working on a car. Always use
common sense. You assume full and complete responsibility for the use of the
information on this page.
Proper vehicle safety requires specific attention
to tires - to inflation pressure, tread depth, and
general tire condition. Over inflated tires run the
risk of explosive decompression (they can pop).
Under inflated tires have a higher rolling resistance
and suffer from rapid tread wear on the edges of the
tread. Excessive tire wear will reduce steering and
braking response. Tires worn down past
their safety margins and into the casing run the
very real risk of rupturing. Tire inflation pressure
and tread depth should be checked regularly in
accordance with the vehicle manufacturer’s
recommendations. Certain combinations of cross ply
and radial tires on different wheels of the same
vehicle can lead to vehicle instability.
Tires should be repaired only at experienced tire
repair shops, and in accordance with the
manufacturer’s recommendations.
US tires have 'wear bars', or "Tread
Wear Indicators" (TWI) molded into the grooves of
the tire. When these become flush with the tops of
the remaining tread, the tire is at the legal limit
of normal safety and must be replaced.
Dangers of aged tires
Research and tests
show that as tires age, they begin to dry out and
become potentially dangerous, even if unused. Aged
tires may appear to have similar properties to newly
manufactured tires; however once the vehicle is
traveling at high speeds the tread could peel off, leading to
severe loss of control and perhaps a rollover.
Many automakers
recommend a six year limit on tires and several tire
manufacturers have called for tires to be removed
from service 10 years after the date of manufacture.

You don't have to live in a wintry climate to encounter icy roads and
hazardous roadways. In temperatures at or just above 32-degrees, a thin layer of
water can turn to or cover ice, causing extremely dangerous, slippery driving
conditions.
KNOW YOUR VEHICLE
Not all cars respond the same to icy, slippery roads. For that reason,
knowing how to handle your vehicle and how it responds in various weather
conditions is important. AAA recommends that motorists practice slow-speed
maneuvers on an empty snow or ice covered parking lot. You should also page
through your owner's manual, familiarizing yourself with your vehicle's braking
system and tire traction.
DISTANCE FACTOR
The most important thing to remember when driving on slick roads is that you
must travel, steer and brake more slowly than usual. The distance needed to stop
on ice is twice as long as that you would need to brake under normal driving
circumstances. This means you should keep at least a three car distance from the
vehicle directly in front of you.
BLACK ICE
Black ice is defined as ice that remains on roadways that are not subjected
to direct sunlight. Black ice commonly forms on roads that wind around lakes and
rivers, in tunnels, on overpasses and in highly shaded, rural areas. Black ice
is almost invisible to the naked eye. Be especially leery when driving your car
into shaded areas, and slow your vehicle down during your approach.
EXTRA SLIPPERY
Certain areas of roadways, because of location or lack of direct sunlight,
are almost always more hazardous than others. Use extra caution when driving on
bridges, overpasses and tunnels.
FRONT WHEEL DRIVE
Front wheel drive vehicles handle better than rear wheel drive on slippery
roads because the weight of the engine is on the drive wheels, which helps to
improve your traction.
REAR WHEEL DRIVE
Because there is virtually no weight on the rear wheels of your car, vehicles
that operate by using rear wheel drive tend to slide from side to side during
turns on icy roads. Cars and light duty truck owners can place bags of sand or
kitty litter in the bed of the truck or trunk to help balance the weight, and
distribute it equally.
KNOW YOUR BRAKES
Your owner's manual will provide information about your braking system. Not
all braking systems are the same. Find out which type of brakes your vehicle
uses and then, follow the safety steps below. ABS Anti-lock braking systems
(ABS) offer significant advantages on slick roads, if used correctly. To operate
ABS effectively, motorists should apply steady pressure to the brake pedal
during the entire stop. ABS will automatically pump the brakes, if necessary, to
keep the wheels from locking. Never manually pump ABS brakes yourself. Apply
only steady pressure continuously until you come to a complete stop. NON-ABS If
you don't have ABS, you should gently apply pumping pressure to your brakes
during slippery conditions. Do not apply steady pressure to your brakes.
Standing on your brakes will only cause wheel lock, and may result in your car
spinning out of control.
LEARN TO HANDLE SKIDS FRONT WHEEL DRIVE
The biggest problem facing most winter drivers is skidding on slick, icy or
snow covered roads. It is possible to steer out of a skid! Once you feel your
car begin to skid, slowly remove your foot from the accelerator, until you feel
your wheels regain traction control. (Do not attempt to brake!) As your
vehicle's tires grab the road, slowly turn the steering wheel in the direction
you want your front wheels to go.
REAR WHEEL DRIVE
When you begin to spin, remove your foot from the gas pedal. Slowly steer in
the direction you want the car to go. If you are still skidding out of control,
counter-steer until your vehicle is pointing in the right direction. Never apply
steady pressure to the brakes.
TIPS
You can improve your VISIBILITY by clearing all snow and ice from your
vehicle. Be sure to remove ice and snow from hood, roof, trunk, turn signal
lights, tail and headlights, windows, mirrors and fenders. Use your LOW BEAMS
when driving in an ice or snow storm. You'll have better visibility. Allow for
greater STOPPING DISTANCE during snow and ice storms. In order to bring
your car to a safe stop, you must allow 8-10 seconds between you and the vehicle
in front of you. Remember that POSTED SPEED LIMITS are only to be
followed during ideal weather conditions. Slow down while driving on snow or
ice. When driving UPHILL on ice, pick a path that will allow the most
traction. Monitor vehicles in front of you and steer clear of areas where they
spin wheels or slide backward. Unpacked snow will give most vehicles sufficient
uphill traction. To maintain control on CURVES and TURNS, reduce
speed just before the turn. Any sudden acceleration or deceleration during a
turn will send you into a skid. NEVER brake while driving on ice. If you
are approaching a patch of ice, brake during your approach. Applying pressure to
your brakes while on ice will only throw you into a skid. Maintain your TIRES.
Tires that are in proper working condition and are adequately inflated provide
better traction. Travel GENTLY. Everything you do on icy roads will
affect how your vehicle handles the situation. Move slowly. Turn slowly. Brake
slowly. Sudden changes can cause your car to spin out of control.
EMERGENCY WEATHER KIT
Having a well stocked emergency kit in your car can help to save your
life and make you more comfortable during breakdowns, accidents and long waits.
Your kit should include: Battery jumper cables First aid kit Shovel Basic tools
(pliers, wrench, screwdriver and knife) Blankets Extra clothing (hats, socks,
boots, mittens) Flashlight Bag of sand Cellular phone or CB.

Driving “defensively” just doesn’t seem to cut it anymore. There are
some measures you can take to ensure your safety. There’s a lot to avoid out
there, but you can steer clear of trouble by just relaxing and taking things
easy. This is meant mostly for freeway gridlock, the most challenging and
frustrating form of traffic. What you’ll find is that the majority of other
drivers out there are “brakers” – people who speed up to slowing traffic
and have to hit their brakes. A good way to ease traffic, both for yourself and
other drivers, is to put a large gap in between your car and the one in front of
you. It’s a pretty basic rule of driving, but it’s often forgotten among all
of our high performance vehicles, cell phones, SUVs and hectic lifestyle.
However, it’s the one thing that can prevent an accident as effectively as
anything else. The recommended space might be one car length per 10
miles-an-hour. It’s better to have at least double that, especially if
you’re traveling at 60 mph or faster. Just imagine the car in front of you
stopping instantly, as if it hit a brick wall. Would you collide into it, or
would you be able to stop in time? The biggest problem that arises from leaving
a good-sized gap is other drivers riding too close behind you. Don’t worry
about them. Try to be courteous and get out of the fast lane if you’re not
keeping up. If you are and you simply have a long gap in front of you, let the
other driver stress out and try to get around. It’s just another person
wanting to hurry up and wait. This brings up another point of good driving. If
ever there is a conflict developing with another driver, let it go. Don’t
gesture back. Don’t race or swerve or suddenly hit your brakes. It’s not
worth risking lives over a little road rage. You’ll find if you relax, leave a
big gap in front of your car and plan your maneuvers, you’ll enjoy the smooth
ride. You can often find “cushion zones” in the herds of cars flying down
the freeway. If you keep your speed right -- not too slow and not too fast --
you can ride in these zones and have all three, four or six lanes to yourself.
This is especially true for long road trips on the interstate. When traffic is
stop and go, try to get a large gap in front again and go slowly. By pacing
yourself, you can roll through the stop-an-go pattern by just going slow. It can
be much less aggravating. It also helps ease traffic as the cars behind you are
not seeing brake lights or hitting their brakes as much. It’s also easier on
your car and the environment. Just remember that there are real people in the
other cars, even though they might just seem like obstacles. By relaxing and
respecting the rules of the road and not rushing yourself, the ride is much more
enjoyable, no matter where you’re going.
Hot Summer Driving
Driving in hot weather: Inspect the auto radiator for leaks and check the fluid.
Check all hoses for possible cracks or sponginess. Make sure all connections are
tight and leak-free. Test the thermostat for proper operation. If it does not
operate at the proper temperature, overheating could occur. Inspect the fan belt
for cracks and proper tension. Belt slippage is a common cause of boilovers. It
also drains electrical power. If loss of coolant has been a problem check for
water seepage on the water pump around the engine block. Don't turn off the
engine when the temperature warning light goes on. If stuck in traffic, shift to
neutral, and race the engine moderately for 30 seconds at two-minute intervals.
Shut off the air conditioner to avoid further overtaxing of the cooling system.
Turn on the heater for a few minutes, it may help. If the radiator continues to
overheat, drive the car off the road, turn off the engine and raise the hood.
Wait at least half an hour before removing the radiator cap, then do it very
slowly and carefully, with the help of a towel or thick rag. Keep your face
turned from the radiator. If your car has the see-through overflow catch tank,
replace any loss of coolant. Don't touch the radiator. If the fluid level is
low, restart the engine while adding cool or warm water as the engine idles.
Road Safety Guide
You never know when you will be driving and your car will decide that it’s
time to break down. If this happens, especially while driving on a lonely road,
it can be frustrating and dangerous. The following is a list of items that you
should always have in your car. It would be a good idea to keep a box in your
trunk just for these items. If you find yourself in this kind of situation, you
will have everything that you need in one place. Check the items at least every
two months in case that you need to replace batteries or anything else. Blanket
(in case it gets too cold) Spare tire in good condition and a jack Extra gas in
proper gas container Booster cable Set of small tools (sockets, pliers, lug
wrench) Charged cellular telephone Paper towels Aspirin Raincoat or umbrella
Water for drinking and/or for engine Working flashlight Antifreeze
Non-perishable foods like chips and pretzels Motor oil, transmission oil, and
break fluid - If you develop a slight leak, you can add enough to get you to a
safe area or the nearest station. (If you don’t know where or how to properly
refill, have someone teach you the proper place and/or way to do this.) Flares -
For alerting other drivers of your stalled car, this can prevent many accidents
from happening. Windshield wiper fluid - During the winter months your car will
get splashed with salted water from the streets, this can cause your windshield
to become blurry to the point of not having any visibility. This coating of salt
water cannot be removed without windshield wiper fluid. Should you find yourself
in this situation, the first thing to do is to call for help, i.e. police, tow
truck, or emergency road service club if you belong to one. You should also call
a family member to let them know of your situation. Next, if the problem is
something that you can take care of like changing a tire, (which you should know
how to do, if you don’t know make it a point to have someone teach you how to
do it), adding antifreeze if your engine is too hot, or adding gas if you ran
out, do it and you can be on your way. If this is the case remember to call the
persons that you spoke to and let them know that everything is okay. Even if
it’s a minor problem always call for help, you have to alert someone of where
you are, you never know what can happen while you are checking the car. It is
always better to be safe than sorry, therefore, someone needs to know of your
location. If, on the other hand, the problem is not something that you can take
care of yourself, take a look at your surroundings to see what type of area you
have been stranded on. If there is a public restaurant, a coffee shop, or a
store nearby that you can go in to wait until help arrives, then that would be
your best bet. Lock your car, raise the hood, and make sure that you take your
cellular phone with you at all times. If there are no visible safe public places
around and depending on how you have assessed the location, you can wait inside
the car, get anything you need from your emergency box, lock the doors and wait
inside the car. If this ever happens to you, you will be thankful that you
decided to be prepared. The kit that you put together will be a great help in
keeping you comfortable from the cold, the rain if you must be outside the car
or have to walk somewhere, from hunger, and especially from being in an area
with no public telephones. Most people are not prepared for this and the
experience can be very frustrating. You may not be able to avoid car breakdowns
but you can make the situation a lot less stressful if you have the basic
emergency needs. Also, if you have children and travel with them often you may
want to add a few things to make their wait less uncomfortable. Having chips
and/or pretzels for children to munch on will help to keep them at ease. Adding
a couple of toys or a favorite book will keep them distracted while waiting for
help to arrive. Don’t get caught unprepared.
How To Be A Safe Driver
All of us have a responsibility to be safe drivers. But even the most careful
drivers can take easy preventative steps to help make them even safer drivers.
If you become one of these drivers, and commit to do the following things, you
may save your own life or the lives of others. Keep Your Visibility High Many
accidents each year are caused by two elements of nature: sun and rain. All of
us have driven on roads that putting the rising or setting sun right in our wind
shields or rear view mirrors. But in sunny weather, most of us do not think
about the hazards of low visibility. Yet sun can be more blinding than the worst
sun or rain. That is why everyone should have a pair of sun glasses in their
cars or on their person at all times. As for rain, making sure your windshield
wipers are in good working order is the most important step. Another problem
comes when the rain stops but mud or water spots are caked on your car's
windshield. Always carry a rag or towel in your car to clean up these hazards to
visibility. Let Others See You As important as watching out for other drivers
is, it is also important to help other drivers to look out for you. One great
way to do this is to leave your headlights on, even during the day. Studies have
shone that day running headlights increase visibility and reduce accidents. Many
new cars have this feature automatically, but for older cars, drivers should
take it upon themselves to turn those headlights on, especially on windy two
lane roads. Calm Down Most of us would never drive drunk. But did you know that
driving while extremely upset is just as bad. If you are extremely angry, sad,
nervous, or sick, you cannot pay proper attention to your driving. And even when
you can pay attention you drive with less skill. If you experience any of these
conditions, postpone your trip. If you are already on the road, pull over to a
safe place and get your bearings. Lost time will be MINIMIZED by avoiding
potentially deadly accidents. Back Off One of the biggest causes of accidents is
following too close. Yet following the car ahead of you too close is senseless:
it can result in being ticketed, it is dangerous, and it doesn't get you
anyplace any faster. Always leave more distance than you think you should have
to between you and the car in front of you. And in the rain, double that
distance. Keep Away Distractions Cell Phones, Automated Direction Systems,
Newspapers, Razors… all of these things are an accident waiting to happen in
the car. Driving requires one's full attention. So communicating, eating,
reading, or doing anything else in the car that isn't driving is a big hazard.
Even if you think you drive perfectly fine while doing these things, you are
still less able to compensate for the mistakes of other drivers when your full
attention isn't directed at defensive driving. Use these tips to help make a
safer road for all of us out there. And always remember, whatever else you do
when you drive, always buckle up.

Before winter sets in it would be a good time to have a
general tune up done especially of the car’s engine. This will ensure that
such items as the ignition, the carburetor, fan belts, are in good working
order and won’t necessarily present any problems later on.
-
While having this done, it would be a good thing to have the
battery checked to see if perhaps a new one is needed.
-
Also a good time to have spark plugs checked, and replaced
with new ones if that is necessary. Checking cables to these plugs also will
ensure they, too, are in good working order.
-
Replacing the air and fuel filters again will ensure that
these won’t present a problem later on.
-
If this hasn’t been done, also replacing or adding more
antifreeze to the cooling system. Depending on how long the antifreeze has
been in the cooling system, it might be a good idea to drain the old fluid,
and then replace it with a mixture of antifreeze and water.
-
Snow tires will be required in the cold climate areas. If
the vehicle is front wheel drive, then front snow tires will be needed. If
the vehicle is rear wheel drive, then mount the snow tires at the rear.
Ensure they are inflated to manufacturer’s specification. Or have chains
put on in those areas that are known for their heavy snowfalls.
-
Windshield washer fluid is a must especially during the
winter driving months. Check periodically to ensure that there is enough
inside the reservoir. Doing this often will alleviate running out of this
fluid when you need it the most, in sloppy weather when windshields are
splattered with mud, making driving all that more difficult.
-
It is a good idea to keep certain supplies inside the trunk
of the vehicle on hand, which would be devoted to winter driving. These will
come in handy whenever forced to drive through snowbound unplowed roads
where the possibility of getting stuck is much greater. The items
recommended are sand or even cat litter for gaining traction beneath the
tires on icy roads. A medium shovel to help dig oneself out in case of
getting stuck in a deep snow drift. A supply of nonperishable foods, such as
box of crackers, canned good, and a can opener and a few eating utensils in
case the roads do become impassable and there is no quick rescue.
-
Also, it is good to have on hand warm blankets, flashlights,
and extra batteries, as well as a cigarette lighter or matches. The matches
should be kept inside a metal container to keep them dry. One use of the
matches might be to thaw out any locks that may become frozen. Although by
lubricating the cylinders inside a lock with graphite (found in auto supply
stores) will help prevent these locks from becoming frozen in the first
place.
-
There is nothing more frustrating than windshield wipers
that don’t work properly when cleaning off the windshield. Ensure these
are working properly, and if they are too worn to do their job, then replace
them with new blades.
-
Ensuring the windshield defroster as well as the rear window
defogger/deicer if present is all working properly will help make driving in
bad weather conditions not only safe but also less frustrating. By taking
the above precautionary measures before the winter sets in, you will help
alleviate most of the foreseeable problems down the line. Also, doing this
will help make winter driving not only safer for everyone on the road, but
also a little less stressful for all those involved.

Carjacking - stealing a car by force - has captured headlines across the
country. Statistically your chances of being a carjacking victim are very slim,
and prevention actions can reduce the risk even more.
Why is Carjacking a Problem?
No one knows for certain, but some explanations include:
-
It's a crime of opportunity - a thief searching for the most vulnerable
prey. Sometimes it's the first step in another crime.
-
For some young people, carjacking may be a rite of passage, a status
symbol, or just a thrill.
-
Cars, especially luxury ones, provide quick cash for drug users and other
criminals.
-
Sophisticated alarms and improved locking devices make it harder for
thieves to steal unoccupied cars.
-
It's easy to buy, steal, or barter for guns in this country. And a pointed
gun makes a powerful threat.
-
More teens and adults commit crimes of violence than ever before.
-
Intense media interest may have created "copycat" carjackers.
Anywhere, Anyone
Most local and state criminal codes don't define "carjacking." It's
reported as either auto theft or armed robbery. This means that no solid
statistics exist on time, place, and victims.
-
Though carjackings can occur anytime, a sizable share appear to take place
during the late night hours.
-
Carjacking isn't just a problem in large cities - it happens in suburbs,
small towns, and rural areas.
-
Carjackers look for opportunity. They don't choose victims by sex, race,
or age.
Golden opportunities: what do carjackers look for?
-
Intersections controlled by stop lights or signs.
-
Garages and parking lots for mass transit, shopping malls, and grocery
stores.
-
Self-serve gas stations and car washes.
-
ATMs (automated teller machines).
-
Residential driveways and streets as people get into and out of cars.
-
Highway exit and entry ramps, or anyplace else that drivers slow down or
stop.
The "Bump and Rob"
It works like this. A car, usually with a driver and at least one passenger,
rear-ends or "bumps" you in traffic. You quickly get out to check the
damage and exchange information. Either the driver or one of the passengers
jumps in your car and drives off.
If you're bumped by another car, look around before you get out. Make sure
there are other cars around, check out the car that's rear-ended you and who's
in it. If the situation makes you uneasy, memorize or jot down the car's tag
number and description; signal the other car to follow you. Drive to the nearest
police station or to a busy, well-lighted area.
If you do get out of the car, take your keys (and purse or wallet if you have
one) with you and stay alert.
Reduce Your Risk
Getting In
-
Walk with purpose and stay alert.
-
Approach your car with the key in hand. Look around and inside the car
before getting in.
-
Be wary of people asking for directions or handing out fliers. Trust your
instincts - if something makes you feel uneasy, get into the car quickly,
lock the doors, and drive away.
On the Road
-
Keep your doors locked and windows rolled up (at least part-way, if it's
hot and you don't have air conditioning), no matter how short the distance
or how safe the neighborhood.
-
When you're coming to a stop, leave enough room to maneuver around other
cars, especially if you sense trouble and need to get away.
-
Drive in the center lane to make it harder for would-be carjackers to
approach the car.
-
Avoid driving alone. Go with someone whenever possible, especially at
night.
-
Don't stop to assist a stranger whose car is broken down. Help instead by
driving to the nearest phone and calling police to help.
Getting Out
-
Park in well-lighted areas, near sidewalks or walkways. Avoid parking near
dumpsters, woods, large vans or trucks, or anything else that limits your
visibility.
-
Never leave valuables in plain view, even if the car is locked. Put them
in the trunk or out of sight.
-
Try to park in a garage with an attendant. Leave only the ignition key,
with no identification.
-
Even if you're rushed, look around before you get out and stay alert to
the surroundings.
If It Happens to You...
-
If the carjacker threatens you with a gun or other weapon, give up your
car. Don't argue. Your life is worth more than a car.
-
Get away from the area as quickly as possible.
-
Try to remember what the carjacker looked like - sex, race, age, hair and
eye color, special features, clothes.
-
Report the crime immediately to the police.
Take Action
-
Work with Neighborhood Watch groups, law enforcement, automobile club, and
other concerned groups to get the word out about carjacking prevention. Try
a special flier, a community forum, posters.
-
Make sure that driver education classes talk to teens about preventing
carjacking and other auto theft.
-
Call the local radio station and ask the manager to air carjacking
prevention tips during commuting hours.
-
Ask your insurance agent or company to put carjacking and other auto theft
prevention information in notices and bills.
-
Enlist parking lot owners, shopping mall security, and transit authorities
to print and distribute educational materials with carjacking prevention
tips.
-
Place carjacking prevention fliers or brochures in the waiting rooms or
dealer service departments, auto repair shops and gas stations.
-
Ask your state's Motor Vehicle Administration to display carjacking and
auto theft prevention advice - posters, handouts, etc.- in its offices and
distribute prevention tips in all mailings.

What Are
Air Bags and How Do They Work?
- Stopping
an object's momentum requires force acting over a period of time. When a car
crashes, the force required to stop an object is very great because the car's
momentum has changed instantly while the passengers' has not. The goal of any
supplemental restraint system is to help stop the passenger with as little
damage to the passenger as possible.
- What an air bag wants to do is to
slow the passenger's speed to zero with little or no damage. The constraints
that it has to work within are huge. The air bag has the space between the
passenger and the steering wheel or dash board and a fraction of a second to
work with. Even that tiny amount of space and time is valuable, however, if the
system can slow the passenger evenly rather than forcing an abrupt halt to the
motion.
- To accomplish its magic, there are
three parts to an air bag
-
The bag itself is made of a
thin nylon fabric, which is folded into the steering wheel or dashboard or,
more recently, the seat or door.
-
The sensor is the device that tells the bag to
inflate. Inflation happens when a collision force equal to running into a
brick wall at 10 to 15 MPH occurs. Sensors detect the crash using a mechanical
switch that closes when a mass shifts and an electrical contact is made.
Electronic sensors use a tiny accelerometer that has been etched on a
silicon chip.
-
The air bag's inflation system
uses the rapid pulse of hot nitrogen gas from the chemical reaction of
sodium azide (NaN3) and potassium nitrate (KNO3) to inflate the bag.
- The inflation system is not unlike a
solid rocket booster. The air bag system ignites a solid propellant and it
burns extremely rapidly to create a large volume of gas to inflate the bag. The
bag then literally bursts from its storage site at up to 200 MPH -- faster than
the blink of an eye! A second later, the gas quickly dissipates through tiny
holes in the bag, thus deflating the bag so you can move.
- Even though the whole process happens in only 1/25th of a second, the
additional time is enough to help prevent serious injury! The powdery substance
released from the air bag, by the way, is regular cornstarch or talcum powder,
which is used by the air bag manufacturers to keep the bags pliable and
lubricated while they're in storage.
How Do I
Stay Safe With An Air Bag?
- It didn't take long to learn that the force of an air
bag can hurt those who are too close to it. Researchers have determined that the
risk zone for driver air bags is the first two to three inches of
inflation. So, placing yourself 10 inches from your driver air bag gives you a
clear margin of safety. Measure this distance from the center of the steering
wheel to your breastbone.
- If you currently sit less than 10 inches away, you can adjust your driving
position in the following ways:
-
Move your seat to the rear as far as
possible while still reaching the pedals comfortably.
-
Slightly recline the back of your
seat. Although car designs vary, most drivers can achieve the 10-inch
distance even with the driver seat all the way forward by slightly reclining
the back of the seat. If reclining the seat makes it hard to see the road,
you can raise yourself up by using your car's seat-raising system (not all
cars have this!) or a firm, non-slippery cushion to achieve the same effect.
-
Point the air bag toward your chest,
instead of your head and neck, by tilting your steering wheel down (this
only works if your steering wheel is adjustable).
- The rules are different for children.
Air bags could seriously injure or even kill an unbuckled child sitting too
close to the air bag or who is thrown toward the dash during emergency braking.
Experts agree that the following safety points are important:
-
Children 12 and under should ride
buckled up in a properly installed, age-appropriate rear car seat.
-
Babies in rear-facing child seats
should never ride in the front seat of a car with a passenger side air bag.
-
If a child over a year old must ride
in the front seat with a passenger side air bag, put the child in a
front-facing child safety seat, a booster seat, or a correct fitting
lap/shoulder belt and move the seat as far back as possible.
- When you are involved in a frontal
collision somewhere in the neighborhood of at least 12-15 mph, a number of
things happen very quickly. The sudden deceleration of your vehicle causes 2
SENSORS to send an electrical signal to the diagnostic module. The diagnostic
module self tests to confirm that a crash event is taking place, then it allows
the signal to trigger the airbag deployment.
Kids in back
Don't put a rear-facing restraint in the front seat. Starting with the first
trip home from the hospital, put an infant in the center back seat. Make sure
the rear-facing restraint is tightly secured to the vehicle with an adult safety
belt and the baby is buckled snugly in.
If there's no choice but to put a baby in the front seat, then
an on/off switch for the passenger airbag is
essential. But before you do this, remember the back seat is safer. Even without
airbags, kids riding in back are much less likely to be killed. Now riding in
back is even more important because it keeps children away from inflating
airbags.
When babies outgrow their rear-facing restraints, they should
graduate to forward-facing ones or booster seats attached to a vehicle's back
seat with an adult safety belt. As kids later graduate to adult belts, proper
restraint use still is essential. Don't put the shoulder portion of a belt
behind a child or under the arm. And don't let a youngster do this, either,
because it compromises protection. A lap belt should be positioned so it's low
and snug across a child's hips, not up over the abdomen.
Older kids should continue riding in a back seat. Only if
there are too many children to put them all in back should a child be allowed to
ride up front. Then make sure the seat is all the way back and the child is
securely buckled and sitting back in the seat. Leaning forward to, for example,
fiddle with radio dials can put a child at risk. If you worry about keeping a
child sitting back, you may wish to consider getting an on/off switch for the
passenger airbag.
Adults: buckle up and sit back
It isn't your size, gender, or age that determines risk. It's position in
relation to an airbag. Most adults can virtually eliminate the risk by buckling
up. Neither short women nor elderly drivers are especially vulnerable if they
use safety belts and sit at least 10 inches from the steering wheel.
Belted drivers potentially at risk of serious airbag injury
are those sitting very close to the steering wheel. But the same drivers would
be at risk without airbags because they're likely to hit the steering wheel hard
-- usually with the face -- in a serious crash. They can reduce the airbag risk
without sacrificing the benefits by sitting back and away from the wheel.
Most drivers, even short ones, can get at least 10 inches from
the steering wheel and still reach the pedals. The problem often is that drivers
sitting closer are leaning forward instead of sitting back in their seats. They
need only sit back. The few who cannot get 10 inches from the steering wheel and
still comfortably reach the pedals may wish to consider pedal extenders.
On/off switches for airbags
The federal government has set criteria for the very few cases when airbag
on/off switches may be needed to avoid injury risk. But getting a driver airbag
switch makes sense only when someone -- for example, a very short person -- has
tried various positions and cannot comfortably drive while sitting back and away
from the steering wheel. A woman late in pregnancy who cannot get her abdomen
away from the steering wheel also may wish to get permission for a switch based
on medical need. But remember that in a serious crash without an airbag, sitting
so close to the wheel means a high risk of hitting it.
Most 1998 and later cars will have redesigned airbags with
less powerful inflators that reduce injury risk. In these cars, there's probably
no need to get an on/off switch for a driver airbag even if you cannot get 10
inches from the wheel. Still, it's best to sit back and away from an airbag.
On the passenger side, there's no significant airbag injury
risk for belted adults sitting back in the seat. The risk for infants and
children can be eliminated by ensuring they ride in a back seat, properly
restrained. The back is safer anyway.
So should you even consider getting an on/off
switch for a passenger airbag? Rarely -- for example, when an infant with
medical problems requires constant observation and the driver is the only other
person in the vehicle. Then there might be no choice except to put the baby up
front, and the airbag would present a risk. Of course, paying constant attention
to a baby distracts from driving and involves its own risks.
Another group is parents who transport too many infants or
small children to put them all in back and are concerned about keeping the child
in front sitting back and away from the airbag. In this case, you may wish to
get an on/off switch. If you do get one, remember to use it correctly. Remember
to turn off the airbag when an infant or child must ride in front.
The decision about airbag on/off switches should be made with
the facts in mind. Then it becomes clear that getting a switch rarely is
necessary. Just take the simple precautions spelled out here to eliminate the
potential risk.
Airbag Checks
What you can do for your Airbag
System?
-
When you get in your vehicle and
turn the key, look at the dash to find your Airbag or SRS light.
-
It should come on for 7-10 seconds
and then go out. This tells you all is well with the Airbag System.
-
If the light does not come on, HAVE
IT CHECKED. After all, it could just be a burnt out light bulb.
-
If the light does not go off after
this period (usually 7-10 seconds) there is a problem
-
If the light comes on while you are
driving, it also needs attention.
You need to take it to a repair shop
that has the equipment to diagnose and repair the problem.
-
Supplemental
Restraint Systems cannot be repaired at home. This is not a challenge. Hand
held Diagnostic equipment that may read the error codes and may be able to clear
them to reset your system are around $3000-$6000. This does not include the cost
of the software involved.
- In addition to the front Airbags, the car companies are putting Airbags in the
doors for side impacts that are not covered by the primary Airbags. They are
putting them in the seats for the drivers and rear passengers as well. This
increases the cost as well as the complexity of the systems.
- Since 1990 the National Highway Traffic Safety Administration, which is
responsible for vehicle safety rules and statistics relating to vehicles, found
that of 19 drivers killed by airbags, only five (5) of them were wearing seat
belts and two of them were determined to be unconscious before the airbag
deployed.
- All new passenger cars were required to have driver and passenger air bags by
Sept. 1, 1997 and all sport utility, minivans and light trucks will be required
to have them a year later.
Crash Sensors
-
Crash Sensors are the
devices that work with the control module to discriminate between crash and
non-crash events. These sensors measure the severity of the impact. They are set
up so that sudden "negative
acceleration" will cause the contacts to close, sending a signal to the
control module which checks for a signal from the rear sensor which must arrive first
to activate the Airbag(s). It is important to note that at least 2 of
these sensors must signal a crash before airbag deployment.
Air Bag On-Off Switches: Questions and
Answers
What does the final rule allow? Beginning January
19, 1998, the final rule allows repair shops and
dealers to install "on-off" switches that allow air bags in
passenger cars and light trucks to be turned on and off in appropriate
circumstances. Dealers and repair shops cannot perform this work without an
authorization letter from the National Highway Traffic Safety Administration (NHTSA).
Vehicle owners can get this authorization letter by filling out a request form
developed by NHTSA and sending it to the agency.
Who can get an on-off switch? Vehicle owners can get on-off switches
installed for one or both air bags in their vehicles if they (or users of their
vehicle) fall into one or more of four specific risk groups.
For both driver and passenger sides:
For the driver side, in addition to medical conditions:
For the passenger side, in addition to medical conditions:
-
Individuals with the need to transport an infant in a rear-facing child
restraint in the front seat because the vehicle has no rear seat, the rear
seat is too small to accommodate a rear- facing child restraint, or
because it is necessary to constantly monitor the child's medical
condition.
-
Individuals with the need to carry children between I and 12-years-old
in the front seat because the vehicle has no rear seat, the consumer must
carry more children than can be accommodated in the rear seat, or because
it is necessary to constantly monitor a child's medical condition.
These are the only four groups that are eligible for the installation of
on-off switches.
How can most people ride safely with air bags? Most people can take
steps that will eliminate or at least significantly reduce any risk without
turning off air bags and losing their protection. The main source of risk is
proximity; an air bag needs space to inflate. Move your seat rearward,
and tilt your seat back - as a driver, you should ride at least 10 inches
(measured from the center of the steering wheel to your breastbone) from the air
bag cover if you can do this while maintaining full control of your vehicle.
Passengers also need to sit at least 10 inches back from the air bag. Wear
your seat belt, and remove any excess slack in the belt. Insist that
children 12-years-old and younger ride in the back seat. Never put a
rear-facing child restraint in front of an air bag.
Who is at risk from air bags? Very few people. Almost everyone is
safer with an air bag than without one. There is a serious risk only if you are
very close to the air bag cover (within 2-3 inches) when the air bag deploys.
On the driver side, if you are one of the relatively few people unable
to get back at least 10 inches from the air bag cover (measured from the
center of the steering wheel center to your breastbone), you may be a candidate
for an on-off switch. At progressively shorter distances, the chances of being
saved by an air bag decreases and the chances of being injured by it increases.
The distance below 10 inches at which you might consider getting an on-off
switch varies from vehicle model to vehicle model, because the risk is affected
by differences in the design and performance of different air bags and crash
sensors. The vast majority of people who currently sit less than 10 inches from
the steering wheel can achieve that distance by moving their seat to the rear as
far as possible (while still being able to comfortably drive the vehicle) and/or
tilting the seat back slightly. If you cannot maintain at least a 10-inch
distance from the air bag, despite your best efforts, you may wish to contact
your dealer or vehicle manufacturer for advice about additional ways of
moving back from your air bag. If you still are unable to come close to
achieving the 10-inch distance, you may wish to consider getting an on-off
switch. Since air bag performance varies among vehicle models, you may wish
to consult your vehicle manufacturer for additional advice. If you do get an
on-off switch, leave the air bag turned on for all drivers who can get back at
least 10 inches.
If you are a driver with a medical condition, you should only turn off
your air bag if you have been advised by a physician that an air bag
poses a special risk to you and this risk outweighs the increased risk
that your head, neck or chest will hit the steering wheel or dashboard in a
crash if your air bag is turned off. Hitting these components can occur even
if you are using your seat belt.
At the recent National Conference on Medical Indications for Air Bag
Deactivation, a group of physicians considered all medical conditions commonly
cited in letters to NHTSA as possible justifications for turning off air bags.
The physicians did not recommend turning off air bags for many relatively
common medical conditions, such as pacemakers, eyeglasses, angina, emphysema,
asthma, breast reconstruction, mastectomy, previous back or neck surgery ,
hyperacusis, tinnitus, advanced age, osteoporosis and arthritis (if the person
can sit at a safe distance from the air bag), or pregnancy. The physicians
recommended turning off an air bag if a safe sitting distance or position cannot
be maintained by a driver because of scoliosis or achondroplasia or by a
passenger because of scoliosis or Down syndrome and atlantoaxial instability
.The physicians also noted that a passenger air bag might have to be turned off
if an infant or child has a medical condition and must ride in front so that he
or she can be monitored. To obtain a copy of the recommendations, call the NHTSA
Hotline or see the NHTSA web site.
Older drivers should follow the advice given above for all drivers.
On the passenger side, all children up through age 12 belong in the
backseat. But, if you must place a rear-facing infant seat in front of an air
bag, get an on-off switch and turn the air bag off. Never place a
rear-facing infant seat in front of an activated air bag.
If children 12 years and younger must sit in the front seat, first
ensure that they use seat belts and/or child restraints appropriate for their
size or weight. Then, move their vehicle seat all the way back. If these steps
are taken, the risk of injury from the air bag will be substantially reduced.
However, since children sometimes lean far forward or slip out of their shoulder
belt, placing themselves in danger, you may wish to consider getting a switch
and turning off the air bag. Since air bag performance varies from vehicle model
to model, you may wish to contact your vehicle manufacturer for advice.
Passengers with medical conditions should follow the advice above for
drivers with such conditions.
People not in any of the above groups will be worse off if they turn off
their air bag. This includes the vast majority of teenagers and adults. By turning
off their air bags, they will increase their chance of death or
serious injury in moderate or high speed crashes.
What if I'm pregnant? Should I disconnect my air bag? No, not unless
you are a member of a risk group. Pregnant women should follow the same advice
as other adults: buckle up and stay back from the air bag. The lap belt should
be positioned low on the abdomen, below the fetus, with the shoulder belt worn
normally. Pull any slack out of the belt. Just as for everyone else, the
greatest danger to a pregnant woman comes from slamming her head, neck or chest
on the steering wheel in a crash. When crashes occur, the fetus can be injured
by striking the lower rim of the steering wheel or from crash forces
concentrated in the area where a seat belt crosses the mother's abdomen. By
helping to restrain the upper chest, the seat belt will keep a pregnant woman as
far as possible from the steering wheel. The air bag will spread out the crash
forces that would otherwise be concentrated by the seat belt.
How do I get an on-off switch? If you are interested in having an
on-off switch installed in a vehicle you own or lease, you first need to get a
copy of NHTSA's information brochure, Air Bags and On- Off Switches:
Information for an Informed Decision, and the accompanying form, Request
for Air Bag On-Off Switch. The brochure and request form are available at
many sources, including NHTSA's web site (http://www.nhtsa.dot.gov), many new
car dealers, state motor vehicle departments, all AAA clubs, and many other
organizations. You also can obtain them by calling NHTSA's toll-free Auto Safety
Hotline at 1-800-424-9393. Read the brochure carefully before filling out the
form; you may decide that an on-off switch is not appropriate for you. If you
decide to request an on-off switch, you must fill out and submit the request
form to NHTSA. The mailing address is provided on the form. You will need to
certify on the request form that you have read the brochure and that you (or
other occupants of your vehicle) fall into one or more of the risk groups for
the air bag(s) for which you request a switch. If the form is properly and
completely filled out, NHTSA will then send you an authorization letter that you
can take to your dealer or repair shop.
You should check with your auto dealer or repair shop to see whether an
on-off switch is available for your vehicle. Also, you should be aware that
dealers and repair shops will not be installing on-off switches before January
19, 1998. Even after this date, it may take a while for switches to become
available for all vehicles. You should also ask how much the switch will cost.
If a switch is available and the dealer or repair shop is willing to install it,
give the- authorization letter directly to- the dealer or repair business. After
the dealer or repair shop installs the on-off switch, it will return a form
(which will be included with the authorization letter) to NHTSA indicating to
the agency it has done the work for you.
Why must I submit the request form to NHTSA? Why can't I just ask a dealer
or repair shop to install an on-off switch? We decided to require this step
to emphasize the importance of taking seriously the safety consequences of
installing an air bag on-off switch. In addition, prior review of requests will
enable the agency to monitor directly, from the very beginning, the
implementation of the regulation and the effectiveness of educational efforts to
promote informed decision making about air bag on-off switches.
Why can't I get an on-off switch now? Why must I wait until January 19,
1998? Manufacturers are just beginning the process of tooling up to produce
on-off switches in volume. They need time to make switches, get them to their
dealers, and for the dealers to get ready. In addition, NHTSA and other safety
groups will be conducting educational efforts to provide consumers with
information on on-off switches, and who should (or should not) consider them.
What if no switch is available after January 19,1998? If the
manufacturer of your vehicle does not make an on-off switch for your model, you
can check with a dealer or repair shop to see whether an "aftermarket"
company (a parts manufacturer other than the vehicle manufacturer) makes a
switch. If there is an aftermarket switch for your model, a dealer or repair
shop can install it for you. Note that there are Federal requirements governing
on-off switches; for example, they must be operated by a key and be equipped
with warning lights to indicate when an air bag has been switched off.
Can consumers get their air bags deactivated instead of
installing a
retrofit on-off switch?
Generally, no. If a retrofit on-off switch is available from the vehicle
manufacturer for a particular vehicle, eligible consumers desiring to disable
their air bags must have a retrofit on-off switch installed; a dealer or repair
shop cannot simply deactivate (or disconnect) the air bags. If a retrofit on-off
switch is not yet available from the vehicle manufacturer for a
particular vehicle, NHTSA will authorize air bag deactivation on a case-by-case
basis under certain circumstances. If a retrofit on-off switch is available only
from an aftermarket company, NHTSA still will authorize air bag deactivation for
eligible people.
Under what circumstances will NHTSA allow air bag deactivation? If the
vehicle manufacturer does not make an on-off switch available for a particular
vehicle, NHTSA will authorize deactivation for the following reasons:
-
A rear-facing infant restraint must be placed in the front seat of a
vehicle because there is no back seat or the back seat is too small for the
child restraint (passenger air bag only).
-
A child 12-years-old or younger must ride in the front seat because the
child has a condition that requires frequent medical monitoring in the front
seat (passenger air bag only ).
-
An individual who drives (or rides in the front seat of) the vehicle has a
medical condition that, on balance, makes it safer to have the air bag(s)
turned off (driver and/or passenger air bag, as appropriate). Each request
based on a medical condition must be accompanied by a written
statement from a physician unless the request is based on a medical
condition for which the National Conference on Medical Indications for Air
Bag Deactivation recommends deactivation.
-
Drivers who must sit within a few inches of the air bag (typically because
they are extremely short-statured, i.e., four feet, six inches or less)
(driver air bag only)
These circumstances apply to me. How do
I get an authorization from
NHTSA to deactivate my air bags? Write a letter to NHTSA, 400 7th Street,
SW, Washington, DC 20590-1000. Requests also can be faxed to (202) 366-3820.
Include: (1) the name and address of the vehicle owner or lessee, (2) the reason
for the deactivation request, and (3) any supporting documentation (for example,
a letter from a physician for all deactivation requests based on medical
conditions for which the National Conference on Medical Indications for Air Bag
Deactivation has not recommended deactivation. The physician's letter
should not only identify the particular condition, but state that, in the
physician's judgment, the condition is such that the potential risk of air bag
deployment outweighs the risk of an air bag not deploying in a crash.).
If the request concerns a child that must ride in the front seat to enable the
driver to monitor the child's medical condition, the supporting physician's
statement must identify the condition and state that frequent monitoring by the
driver is necessary.
If the request is approved, NHTSA will send you a letter authorizing
deactivation, an agency information brochure, labels alerting vehicle occupants
about the deactivated air bags, and a form to be filled out and mailed back to
the agency regarding the deactivation. You should then call your dealer or
repair shop and ask whether it will disconnect the air bag. Some dealers and
repair businesses have a policy of not disconnecting air bags. NHTSA cannot
require them to deactivate air bags; however, most people
should be able to find a qualified automotive mechanic or technician who will do
the work.
NHTSA strongly urges owners and lessees to have the air bag reactivated if
the condition that causes the deactivation ceases to exist, or if they sell the
vehicle. If the vehicle is sold, and the air bag is not reactivated, the new
owner needs to be notified.
Will NHTSA allow or require manufacturers to install on-off switches in
new vehicles? NHTSA allows vehicle manufacturers to install passenger air
bag on-off switches in new vehicles in limited circumstances.
"Factory-installed" passenger air bag on-off switches are allowed in
new vehicles only if they do not have rear seats, or if the rear seat is too
small to accommodate a rear-facing child restraint.
"Factory-installed" on-off switches are not allowed for the driver air
bag in any new vehicle. Manufacturers are not required to install on-off
switches in any new vehicle.
NHTSA decided against requiring or allowing on a widespread basis on-off
switches as "factory- installed" equipment for several reasons. First,
the switch is tied to a person in a risk group; the agency was concerned that
extending the option of on-off switches to all new vehicles might result in
on-off switches being installed as standard equipment in all new vehicles, thus
resulting in on-off switches being installed without regard to whether
individual consumers were at risk. NHTSA also was concerned that integrating
on-off switches into new vehicles, which probably would require redesigning
instrument panels, would divert resources from the development of more
sophisticated air bag systems.
I am buying a new car, and want an air bag on-off switch. Can I have one
installed? Yes. If you decide you want one (and you or a user of your
vehicle falls into one of the risk groups), starting January 19, 1998, a dealer
or repair shop can install an on-off switch in a new car or light truck, if you
have an authorization letter from NHTSA. Remember, in order to request a switch,
you must know the vehicle identification number of your vehicle and write it on
your request form.
What about vehicles with "depowered" air bags? Can on-off
switches be installed in these vehicles? Yes, you can have an on-off switch
installed in a vehicle with a depowered air bag. However, depowered air bags
will reduce the risk of injury caused by air bags. On the driver side, depowered
air bags are expected to substantially reduce any air-bag-related risks for
short drivers. On the passenger side, NHTSA believes that, with depowered air
bags, there would be almost no chance of fatality to a properly-belted child
sitting back from the air bag. There still would be a substantial risk for an
infant in a rear-facing child restraint and for unrestrained or out-of-position
children ages 12-and-under. Even if you or a user of your vehicle fall within
one or more of the risk groups eligible for an on-off switch; you should consult
with your vehicle manufacturer before installing an on-off switch in a vehicle
with depowered air bags.
What about rental cars? Rental car companies will be able to have
switches installed in their vehicles if they believe the vehicles will be used
by people in one or more of the four risk groups.
Why should I leave the air bags in my vehicle turned on? Motor vehicle
crashes are the leading cause of death for each age, 5 through 27 years old. Air
bags reduce the risk of dying in a direct frontal crash by about 30 percent. Air
bags have saved over 2,600 lives through November 1, 1997. They also have
prevented a large number of serious head and chest injuries. Overall, air bags
add to the protection offered by seat belts. In the vast majority of cases,
adults are safer with an air bag that is "on. "
How can I get more information? Informational brochures will be
available through auto dealers, State motor vehicle departments, AAA clubs, or
from the National Highway Traffic Safety Administration directly. You can call
the agency's toll-free Auto Safety Hotline at 1-800-424-9393 or you can visit
NHTSA's site on the World-Wide Web at http://www.nhtsa.dot.gov. Click on the air
bag icon for detailed information that should help you make an informed decision
about air bag use in your vehicle. Copies of the necessary information brochure
and request form also can be downloaded from the NHTSA web site.
*Iautoinfo.com would like to thank the NHTSA for
sending us this air-bag information*

If your car has ABS,
apply firm, steady pressure to the brake pedal whenever you need to stop.
Many of today’s cars are equipped
with ABS, or anti-lock braking systems, but not many drivers know how to use
them properly. Re-read your car’s owner’s manual to learn more about the
proper use of ABS.
If your car has ABS, the ABS logo will
appear on your dashboard every time you start the car.
In the event of a skid, anti-lock
brakes rely on a computer in the car to pump the brakes more rapidly than you
could pump them yourself. To make the system work, apply firm, steady pressure
to the brake. When the ABS kicks in, you will feel a vibration or pulsating
sensation on the brake pedal. Many drivers mistakenly believe this sensation
signals a fault in the system. On the contrary, it means ABS is working
properly.
While the ABS is pumping the brakes
very rapidly, the wheels will continue turning. This gives you control over the
vehicles steering. In other words, you may be able to steer around an obstacle,
such as the car in front of you.
Since many drivers aren’t accustomed
to being able to steer while skidding, they over steer and risk running off the
road. Be careful to turn the steering wheel just enough to avoid obstacles.
In summary, if your car has ABS, follow
this braking procedure:
-
When you need to stop, apply firm,
steady pressure to the brake pedal.
-
Gradually steer the car around any
obstacles.
-
Release pressure on the brake.
-
Resume driving normally, but consider
lowering your speed.
