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 two mi tes 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 nee.d regular maintenance.
Adding Equipment to Your Air
Bag-Equipped
V
Q: If I add a push bumper or a bicycle rack to the
front of my vehicle, will
it keep the air bags
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 bags from working properly
in a crash.
e.' Is there anything I might add to the front of the
vehicle that could keep the air bags 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 questions 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 Satisfxtion Procedure
in this manual.
See ;'Customer Satisfiction Procedure"
in the Index.)

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won’t
work at the normal range
in any location. If you have to
get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
NOTICE:
When replacing the battery, use care not to touch
any
of the circuitry. Static from your body
transferred
to these surfaces may damage
the transmitter.
To replace the battery in the keyless entry transrnitter:
I
1. Insert a dime in the slot between the covers of the
transmitter housing near the key ring hole. Remove
the bottom by twisting the dime.
2. Remove and replace the battery with a three volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter.
5. Check the operation of the transmitter.

I NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to be
drained much sooner. And the excessive heat can
damage your starter motor.
2. If it doesn’t start right away, hold your key in
START. If it doesn’t start in 10 seconds, push the
accelerator pedal
all the way down for five more
seconds, unless
it starts sooner.
3. If your engine still won’t start (or starts but then
stops), wait
15 seconds and start over.
When
the engine starts, let go of the key and the
accelerator pedal.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle.
If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to do it
without damaging your vehicle. See “Towing

headlamps behind you. A photocell on
the back of the
mirror senses when it is becoming dark outside. Another
photocell
built into the mirror surface senses when
headlamps are behind you.
