Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from
doing its job, have it repaired.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)
Notice:If you damage the covering for the driver’s
or the right front passenger’s frontal airbag, or
an airbag covering (if equipped) on a seatback, the
airbag may not work properly. You may have to
replace the airbag module in the steering wheel,
both the airbag module and the instrument panel for
the right front passenger’s frontal airbag, or both
the airbag module and the seatback for seating
positions with a side impact airbag (if equipped).
Do not open or break the airbag coverings.

The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open the rear door while the security lock is engaged,
unlock the door and open the door from the outside.
Lockout Protection
This feature protects you from locking your key in the
vehicle when the key is in the ignition and a door is open.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all of the doors will lock
and then the driver’s door will unlock.
Liftgate
{CAUTION:
It can be dangerous to drive with the liftgate
glass, liftgate or rear doors open because
carbon monoxide (CO) gas can come into your
vehicle. You cannot see or smell CO. It can
cause unconsciousness and even death.
CAUTION: (Continued)
CAUTION: (Continued)
If you must drive with the liftgate glass,
liftgate, or rear doors open, or if electrical
wiring or other cable connections must pass
through the seal between the body and the
liftgate glass, liftgate, or rear doors:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed with the
recirculation mode off. That will force
outside air into your vehicle. SeeClimate
Control System on page 3-22.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-35.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make
it impossible to steal.
Content Theft-Deterrent
Your vehicle may be equipped with a content
theft-deterrent alarm system.
The security light
is located on the
instrument panel
cluster. SeeSecurity
Light on page 3-49for
additional information.
To activate the theft-deterrent system, do the following:
1. Close all the doors.
2. Lock the door with the remote keyless entry
transmitter. The security light should come
on and ash.If the lock button on the remote keyless entry
transmitter is pressed, but a door is open, you may
hear three chimes indicating delayed locking is
enabled. SeeDelayed Locking on page 2-10for
additional information. Close the door and the
content theft-deterrent system will be activated.
If a locked door is opened without using the remote
keyless entry transmitter or OnStar, if equipped with
an active subscription, the alarm will go off. Your
vehicle’s lamps will ash and the horn will sound for
about two minutes, then will turn off to save the battery
power. If this occurs, you can turn off the alarm by
pressing unlock on the remote keyless entry transmitter
or by placing the key in the ignition and turning it
to START.
If your vehicle has a Driver Information Center (DIC),
you can customize your alarm warning. SeeDIC Vehicle
Customization on page 3-67for additional information.
The horn may chirp for 10 seconds before the alarm
goes off if the theft-deterrent system is activated using
the remote keyless entry transmitter and the driver’s
door is opened. If this occurs, you can turn off the
alarm by pressing unlock on the remote keyless entry
transmitter or by placing the key in the ignition and
turning it to START.
2-17

Here is how to avoid setting off the alarm by accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door key after the doors are closed.
Always unlock a door with the remote keyless
entry transmitter.
If you set off the alarm by accident, turn off the alarm
by pressing unlock on the remote keyless entry
transmitter or by placing the key in the ignition and
turning it to START.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, activate the system by
locking the doors with the remote keyless entry
transmitter.
2. Wait for the security light to go out.
3. Unlock the door with the manual door lock and
open the door. This should set off the alarm.
4. Turn off the alarm by pressing unlock on the remote
keyless entry transmitter or by placing the key in
the ignition and turning it to START.
If the alarm does not sound when it should,
but the vehicle’s headlamps ash, check to see
if the horn works. The horn fuse may be blown.To replace the fuse, seeInstrument Panel Fuse
Block on page 5-107andUnderhood Fuse Block
on page 5-109.
If the alarm does not sound or the vehicle’s headlamps
do not ash, see your dealer for service.
Passlock®
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock
®is a passive theft-deterrent system. Passlock®
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled.
If the engine stalls and the security light ashes, wait
until the light stops ashing before trying to restart
the engine. Remember to release the key from START
as soon as the engine starts.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the engine
off. However, your Passlock
®system is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by Passlock
®at this time. You
may also want to check the fuse. SeeFuses and Circuit
Breakers on page 5-106. See your dealer for service.
In an emergency, call the GM Roadside Assistance
Center. SeeRoadside Assistance Program on page 7-6.

Automatic Transmission Operation
There are several different positions for your shift lever.
Your vehicle is equipped with an automatic transmission
and features an electronic shift position indicator
within the instrument panel cluster. This display must
be powered anytime the shift lever is capable of
being moved out of PARK (P).
PARK (P):This position locks your rear wheels.
It is the best position to use when you start your
engine because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not 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.
CAUTION: (Continued)
CAUTION: (Continued)
To be sure your vehicle will not move, even
when you are on fairly level ground, always
set your parking brake and move the shift
lever to PARK (P). SeeShifting Into Park (P)
on page 2-32. If you are pulling a trailer, see
Towing a Trailer on page 4-60.
{CAUTION:
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. So, be sure the transfer case is
in a drive gear, two-wheel high, four-wheel
high or four-wheel low — not in NEUTRAL.
SeeShifting Into Park (P) on page 2-32.
2-23

When Tow/Haul mode
is selected the
Tow/Haul indicator
light will illuminate.
The Tow/Haul mode also interacts with the Autoride
®
feature, if equipped, to enhance the ride when trailering
or with a loaded vehicle. SeeAutoride®on page 4-60.
Four-Wheel Drive
If your vehicle has four-wheel drive, you will see the
buttons shown below. You can send your engine’s
driving power to all four wheels for extra traction.
To get the most satisfaction out of four-wheel drive,
you must be familiar with its operation. Read the
part that follows before using four-wheel drive.
Notice:Driving on clean, dry pavement in
Four-Wheel-Drive High or Four-Wheel-Drive Low for
an extended period of time may cause premature
wear on your vehicle’s powertrain. Do not drive on
clean, dry pavement in Four-Wheel Drive High or
Four-Wheel-Drive Low for extended periods of time.The transfer case buttons
are located to the left
of the instrument panel
cluster.
The front axle locks and unlocks automatically when
you shift the transfer case. Some delay for the axle
to lock or unlock is normal.
For information on StabiliTrak
®, seeStabiliTrak®
System on page 4-9.
Use these buttons to shift into and out of
four-wheel drive.
