Servicing Your Air Bag-Equipped Vehicle
The air bag affects 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
GM 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 Inde-x.
~~ -
A CAUTION:
For up to two 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.
Adding Equipment to Your Air
Bag-Equipped Vehicle
Q: If I add a push bumper or a bicycle rack to the
front
of my vehicle, will it keep the air bag from
working properly?
A: As long as the push bumper or bicycle rack is
attached to your vehicle
so that the vehicle's basic
structure isn't changed, it's
not likely to keep the
air bag from working properly
in a crash.
Is there anything I might add to the front of the
vehicle that could keep the air bag from
working properly?
A: Yes. If you add things that change your vehicle's
frame. bumper system, front end sheet metal or
height, they may keep the air bag system from
working properly.
Also, the air bag system may not
work properly if you relocate any of the air bag
sensors.
If you have any question about this, you
should contact Customer Assistance before you
modify your vehicle.
(The phone numbers and
addresses for Customer Assistance are
in Step Two of
the Customer Satisfiction Procedure
in this manual.
See "Customer Satisfaction Procedure"
in the Index.)

Brake Pedal Travel
See your dealer if the brake pedal does not return to
nor~nal height, or
if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
If your brake pedal goes down farther than normal. your
rear drum brakes may need adjustment. Adjust them
by
backing up and firmly app1yin.g the brakes a lew times.
Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its
many parts have to be of top quality and work well
together
if the vehicle is to have really good braking.
Your vehicle was designed and tested
with top-quality
GM brake parts. When
you replace parts of your braking system
-- for
example, when your brake linings wear down and you
haw to have new ones
put in -- be sure you get new
approved
GM replacement parts. If you don’t, your
brakes may
no longer work properly. For example, if
someone puts in brake linings that are wrong for your
vehicle, the balance between
your front and rear brakes
can change
-- for the worse. The braking performance
you’ve come to expect can change
in many other ways if
someone puts in the wrong replacement brake parts.
Battery
Every new vehicle has a Delco Freedom@ battery. You
never have to add water to one of these. When it’s time
for a new battery, we recomlnend a Delco Freedom
battery. Get one that has the replacement number shown
on the original battery‘s label.
