How does an air bag restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel or
the
instrument panel. Air bags supplement the protection
provided by safety belts. Air bags distribute
the force of
the impact more evenly over the occupant’s upper body, stopping
the occupant more gradually. But air bags would
not help
you in many types of collisions, including
rollovers, rear impacts and side impacts, primarily because
an occupant’s motion is not toward those air bags. Air
bags should never be regarded
as anything more than a
supplement to safety belts, and then only in moderate to
severe frontal or near-frontal collisions.
What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module
-- the
steering wheel hub for the driver’s air bag, or the
instrument panel for the right front passenger’s
bag
-- will be hot for a short time. The parts of the bag
that come into contact with
you may be warm, but not
too hot
to touch. There will be some smoke and dust
coming from vents in the deflated air bags. Air bag
inflation doesn’t prevent the driver from seeing or from
being able to steer the vehicle, nor does
it stop people
from leaving the vehicle.
dta CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma
or other
breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as it is safe to
do so.
If you have breathing problems but can’t get out
of the vehicle after an air bag inflates, then get
fresh air
by opening a window or door.

Air bags are designed to inflate only once. After they
inflate, you’ll need some new parts
for your air bag
system. If
you don’t get them, the air bag system
won’t be there
to help protect you in another crash.
A new system will include air bag modules and
possibly other parts.
The service manual for your
vehicle covers
the need to replace other parts.
Your vehicle is equipped with
a crash sensing and
diagnostic module, which records information about the air bag system.
The module records information
about the readiness of the system, when
the sensors are
activated and driver’s safety belt usage at deployment.

Let only qualified technicians work on your air bag
system. Improper service can mean that your air
bag system won’t work properly. See
your dealer
for service.
NOTICE:
If you damage the covering for the driver’s or the
right front passenger’s air bag, the bag may not
work properly.
You may have to replace the air
bag module
in the steering wheel or both the air
bag module and the instrument panel for the
right front passenger’s air bag.
Do not open or
break the
air bag coverings.
If your vehicle ever gets into a lot of water -- such as
water up
to the carpeting or higher -- or if water enters
your vehicle and
soaks the carpet, the air bag controller
can be soaked and ruined. If this ever happens, and then
you start your vehicle, the damage could make the air
bags inflate, even if there’s no crash.
You would have to
replace
the air bags as well as the sensors and related
parts.
If your vehicle is ever in a flood, or if it’s exposed
to water that soaks the carpet, you can avoid needless
repair costs by turning
off the vehicle immediately. Don’t
let anyone start the vehicle,
even to tow it, unless
the battery cables are first disconnected.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts
of the air bag system in several places
around your vehicle.
You don’t want the system to
inflate while someone
is working on your vehicle. Your
dealer and the
GM Service Manual have information
about servicing your vehicle and the air bag system.
To
purchase a service manual, see “Service and Owner
Publications” in the Index.
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service.
You
can be injured if you are close to an air bag when
it inflates. Avoid wires wrapped with yellow tape
or yellow connectors. They are probably part of
the air bag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualified to
do so.
The air bag system does not need regular maintenance.

Electronic Road-Speed Governor
(Gasoline Engines) (Option)
This optional system automatically controls vehicle top
speed. The system controller receives
a signal from the
vehicle speed sensor and reduces power when the
vehicle speed reaches the maximum
65 mph (105 kdh)
governed speed.
Warning Lights, Gages
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details
on the next few pages, some
warning lights come
on briefly when you start the
engine just to let you know they’re working.
If you are
familiar
with this section, you should not be alarmed
when this happens. Gages
can indicate when there may be or is
a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to let you know when
there’s
a problem with your vehicle.
When one of the warning lights comes on and
stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights
and gages. They’re
a big help.
Safety Belt Reminder Light
When the key is turned to RUN or START, a tone will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about
20 seconds, then it
will flash for about
5 5 seconds.
If the driver’s belt is already buckled, neither the tone
nor the light will come on.
