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.)

Operation
When you press UNLOCK. the driver's door and
endgate will unlock automatically.
If you press
UNLOCK
again within five seconds. all doors will
unlock. Press LOCK to lock all the doors.
Press the
REAR button twice within 3 1/2 seconds to
unlock and unlatch the rear glass. If your vehicle has
an automatic transmission. the transmission must be
in PARK (P) or NEUTRAL (N). If your vehicle has
a manual transmission, you must engage the
parking brake.
Matching Transmitter(s) To Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen. a replacenm~t can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to yo~~r
dealer. When the doaler matches the replacement
transmitter to your
c.ehicle, any renlaining transmitters
Inust
also be matched. Once yo~~r dealer has coded the
new translnitter. the
lost transmitter will not unlock your
vehicle. Each vehicle can have
only two transmitters
matched
to it.
Battery Replacement
Under normal LIS~. 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
it's probably time to change the battery.

1 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 transmitter: Resynchronization
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.
CR2032
or equivalent battery, positive (+)
side down.
2.
Remove and replace the battery with
a three volt
3. Align the covers and snap them together.
4. Check the operation of the transmitter. Resynchronization may
be necessary due to the security
method used
by this system. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal it has been sent previously.
This prevents anyone from recording and playing back
the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and simultaneously press
and hold the LOCK
and
UNLOCK buttons on the transmitter for at least
five seconds. The door locks should cycle to confirm
synchronization. If the locks
do not cycle,
see your dealer
for service.

NOTICE:
Don’t operate accessories in the ACCESSORY
position for long periods of time. Prolonged
operation of accessories in the ACCESSORY
position could drain your battery and prevent
you from starting your vehicle.
LOCK
(B): This position locks your ignition, steering
wheel and transmission. It’s
a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned
to LOCK.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. Use OFF if you must have
your vehicle in motion while the engine is off (for
example, if your vehicle is being towed).
RUN (D): This is the position for driving.
START (E): This starts your engine.
On manual transmission vehicles, turning the key
to
LOCK will lock the steering column and result
in a loss
of ability to steer the vehicle. This could
cause a collision.
If you need to turn the engine
off while the vehicle is moving, turn the key only
to
OFF. Don’t press the key release button while
the vehicle is moving.
I NOTICE: I
If your key seems stuck in LOCK and you can’t
turn it, be sure you are using the correct key;
if
so, is it all the way in? If it is, then turn the
steering wheel left and right
while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it
could break the key or the
ignition switch.
If none of this works, then your
vehicle needs service.

Manual Transmission
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 clown I‘or five 11101-e
seconds, or until it starts.
I 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.

Automatic Transmission Operation
Your automatic transmission may have a shift lever
located
on the console between the seats or on the
steering column.
There are several different positions for
YOLK shift lever.
If your vehicle is equipped with a column shift lever. it
features an electronic shift position indicator within the
instrument cluster. This display must be powered
anytime the
shift lever is capable of being moved out of-’
the PARK (P) position. This means that if your key is in
the OFF position, but not locked, there will be a snnall
current drain on your battery which could discharge
your battery over a period of time. If you need to leave
your key
in the ignition in the OFF position for an
extended period, it is recommended that you disconnect
the battery cable from the battery to prevent discharging
your battery.
PARK (P): This locks your rear wheels. It’s the best
position to use when
YOLI start your engine because yo~~r
vehicle can’t move easily. It
is dangerous to get out of your
vehicle if the
shift lever is not fully in
PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine
is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured.
To be sure your
vehicle won’t move, even when you’re on fairly
level ground, always set your parking brake and
nwve the shift lever to
PARK (P).
If you have four-wheel drive, your vehicle will
be free to roll
-- even if your shift lever is
in
PARK (P) -- if your transfer case is in
NEUTRAL (N). So, be sure the transfer case is in
a drive gear, two-wheel high
(2HI) or four-wheel
high
(4HI) or four-wheel low (4LO) -- not in
NEUTRAL (N). See “Shifting Into PARK (P)” in
the Index.
If you’re pulling a trailer, see “Towing
a Trailer” in the Index.
