release latch plates for
the lap shoulder belts
on the bench seat to be
removed. To do this,
press the tip of a key
into the release hole of
the safety belt buckle
while pulling up on the
safety belt.2. Locate the pins.
There are two pins located on the inboard sides

the pins will be located under a ap that has
been cut into the mat. The driver’s side pin has
a gray cap with a black “L” marked on it and
will look like this:

The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it’s more
likely that the fetus won’t be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-15.
The right front passenger’s safety belt works the same
way as the driver’s safety belt – except for one thing.
If you ever pull the shoulder portion of the belt out all the
way, you will engage the child restraint locking feature.
If this happens, just let the belt go back all the way
and start again.
Center Passenger Position
(2nd Row)
If your vehicle has a second row bench seat, someone
can sit in the center position. When you sit in the
center position in the second row bench seat, you have
a lap-shoulder belt which works the same way as the
rear seat outside passengers’ belts. To learn how
to wear a lap-shoulder belt see, “Lap-Shoulder Belt”
underRear Seat Passengers on page 1-27.
1-24

To turn off the right front passenger’s air bag, insert
your ignition key into the switch, push in, and move the
switch to AIR BAG OFF.
The AIR BAG OFF light will come on to let you know
that the right front passenger’s air bag is off. The
right front passenger’s air bag will remain off until you
turn it back on again, and the AIR BAG OFF light
will stay on to remind you that the air bag is off.
{CAUTION:
If the air bag readiness light ever comes on
when you have turned off the air bag, it means
that something may be wrong with the air bag
system. The right front passenger’s air bag
could inate even though the switch is off. If
this ever happens, don’t let anyone whom the
national government has identied as a
member of a passenger air bag risk group sit
in the right front passenger’s position (for
example, don’t secure a rear-facing child
restraint in your vehicle) until you have your
vehicle serviced.
1-79

To turn the right front passenger’s air bag on again,
insert your ignition key into the switch, push in,
and move the switch to the on position.
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
inate while someone is working on your vehicle. Your
dealer and the service manual have information
about servicing your vehicle and the air bag system.
To purchase a service manual, seeService Publications
Ordering Information on page 7-12.
{CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an
air bag can still inate during improper
service. You can be injured if you are close to
an air bag when it inates. 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 qualied to do so.
The air bag system does not need regular maintenance.

{CAUTION:
Leaving children in a vehicle with the ignition

This vehicle has one
double-sided key for the
ignition and door locks. It
will t with either side up.
When a new vehicle is delivered, the dealer provides the
owner with a pair of identical keys and a bar-coded tag.
The bar-coded tag has a code on it that tells your dealer
or a qualied locksmith how to make extra keys. Keep
this tag in a safe place. If you lose your keys, you’ll be
able to have new ones made easily using this tag.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If you ever do get locked out of your vehicle, call GM
Roadside Assistance Center. SeeRoadside Assistance

1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.

2-3

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization” under
“Remote Keyless Entry System Operation” following
this section.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
Your vehicle may have this feature.
Q(Lock):Press this
button once to lock all of
the doors. The parking
lamps will ash and
the interior lamps will turn
on briey. Press the
lock button again within ve
seconds and the parking
lamps will ash and
the horn will chirp briey.
W(Unlock):Press this button once to unlock the

2-4

L(Panic Alarm):The remote keyless entry transmitter
comes equipped with an instant panic alarm. To use
the alarm, press the horn symbol while the ignition
is turned off. The horn will sound and both the interior
and exterior lamps will ash for up to thirty seconds.
To stop the instant panic alarm, press the panic button
again, wait for thirty seconds, or start the vehicle.
j(Cargo Door):Press this button to unlock the cargo
doors only.
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 replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
Resynchronization
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 that 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 press and hold the lock and unlock
buttons on the transmitter at the same time for seven
seconds. The door locks should cycle to conrm
synchronization. If the locks do not cycle, see your
dealer for service.
