switch or press the door unlock button on
the Remote Keyless Entry (RKE) transmitter twice.
SeeRemote Keyless Entry System Operation
on page 113.
To open the liftglass, press the button on the
underside of the license pocket applique (A).
The liftglass can also be opened by pressing the
liftglass release button on the RKE.To open the entire liftgate, press the touchpad
on the underside of the liftgate handle (B).
The vehicle must be in PARK (P) to open the
liftgate. To close the liftgate, use the pull cup or
pull strap as an aid.
The liftgate or liftglass cannot be opened if the
rear wipers are in motion. Attempting to open the
liftgate or liftglass while the rear wipers are in
motion will cause the release of the liftglass
or liftgate to delay until the wipers are moved off
the liftglass.
Both the liftglass and liftgate have an electric
latch. If the battery is disconnected or has
low voltage, the liftglass and liftgate will not open.
The liftglass and liftgate will resume operation
when the battery is reconnected and charged.
If the battery is properly connected and has
adequate voltage, and the liftgate or liftglass still
will not function, your vehicle should be taken to a
dealership for service.

Obstacle Detection Features
If the liftgate encounters an obstacle during a
power open or close cycle, a warning chime will
sound and the liftgate will automatically reverse
direction to the full closed or open position.
After removing the obstruction, the liftgate may be
power opened or closed normally. If the liftgate
encounters multiple obstacles on the same power
cycle, the power function will deactivate, and
the liftgate will switch to manual operation.
The REAR ACCESS OPEN warning message in
the Driver Information Center (DIC) will indicate
that the liftgate is open. After removing the
obstructions, manually open the liftgate to the full
open position or close the liftgate to the fully
closed and latched position. The liftgate will now
resume normal power operation.
Your vehicle has pinch sensors located on the
side edges of the liftgate. If an object is caught
between the liftgate and the body and presses
against this sensor, the liftgate will reverse
direction and open fully. The liftgate will remain
open until it is activated again or closed manually.
Manual Operation of Power Liftgate
To change the liftgate to
manual operation,
toggle the switch on the
overhead console to
the “Disable” position
indicated by a circle.
With the power liftgate disabled and the door
unlocked, the power liftgate can be manually
opened and closed.
To open the liftgate, press the touchpad on the
handle on the outside of the liftgate, and lift
the gate open. To close the liftgate, use the pull
cup or pull strap to lower the liftgate and close.
The liftgate latch will power cinch to closed
position. Always close the liftgate before driving.
If the RKE button or the power close button on the
liftgate is pressed while power operation is
disabled, the lights will ash three times, but the
liftgate will not move.

Power Windows
The power window controls are located on each of
the side doors.
The driver’s door has a switch for the passenger
and rear windows also. The power windows
work when the ignition has been turned to
ACCESSORY or RUN or when Retained
Accessory Power (RAP) is active. See
Retained Accessory Power (RAP) on
page 138.
Press the switch to lower the window.
Pull up on the front edge of the switch to raise the
window.
Express-Down Windows
The driver and front passenger windows have an
express-down feature that allows the windows
to be lowered without holding the switch. Press
down fully on the window switch, then release,
to activate the express-down mode. The
express-down mode can be canceled at any
time by pulling up on the switch.

sun visor from the center mount and slide it
along the rod from side-to-side to cover the driver
or passenger side of the front window. Swing
the sun visor to the side to cover the side window.
It can be moved along the rod from side-to-side
in this position also.
Lighted Visor Vanity Mirror

on both the driver’s and passenger’s sun visors.
Pull the sun visor down and lift the mirror cover to
turn the lamps on.
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 have a content theft-deterrent
alarm system.
To activate the theft-deterrent system, do the
following:
1. Open the door.
2. Lock the door with the Remote Keyless Entry
(RKE) transmitter. The security light should
come on and ash. The door does not need to
be open.
If the delayed locking feature is active, the
alarm will not be activated until all doors are
closed and the security light goes off.
3. Close all doors. The security light will stop
ashing and go off after approximately
30 seconds. The content theft deterrent alarm
is not armed until the security light goes off.
132

If a door is opened without using the RKE
transmitter, a ten second pre-alarm will occur.
The horn will chirp and the lights will ash. If the
key is not placed in the ignition and turned to
START or the door is not unlocked by pressing the
unlock button on the RKE transmitter during the
ten second pre-alarm, the alarm will go off.
Your vehicle’s headlamps will ash and the horn
will sound for about two minutes, then will turn
off to save the battery power.
The theft-deterrent system will not activate if you
lock the doors with a key, the manual door lock, or
the power door lock switch. It activates only if you
use the RKE transmitter. You should also
remember that you can start your vehicle with the
correct ignition key if the alarm has been set off.
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 RKE transmitter.
Unlocking a door any other way will set off the
alarm if the system has been armed.If you set off the alarm by accident, turn off the
alarm by pressing unlock on the RKE 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, lower the driver’s
window and open the driver’s door.
2. Activate the system by locking the doors with
the RKE transmitter.
3. Get out of the vehicle, close the door and wait
for the security light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the
door. This should set off the alarm.
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, seeFuses and Circuit Breakers
on page 540.
If the alarm does not sound or the vehicle’s
headlamps do not ash, see your dealer for
service.

Retained Accessory Power (RAP)
Your vehicle has a Retained Accessory Power
(RAP) feature which will allow certain features on
your vehicle to continue to work up to 10 minutes
after the ignition key is turned to LOCK.
The radio, power windows, and if the vehicle
has these features, the sunroof and OnStar
®
System, will work when the ignition key is in
RUN or ACCESSORY. Once the key is turned
from RUN to LOCK, these features will continue
to work for up to 10 minutes or until a door is
opened.
Starting the Engine
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position — that is a safety feature.
To restart when you are already moving, use
NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if
your vehicle is moving. If you do, you could
damage the transmission. Shift to PARK (P)
only when your vehicle is stopped.1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as your engine gets warm.
Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects the electrical
system. If the ignition key is turned to the
START position, and then released when the
engine begins cranking, the engine will continue
cranking until the vehicle starts or until it
exceeds the maximum cranking time allowed,
approximately 15 seconds to prevent cranking
motor damage. To prevent gear damage, this
system also prevents cranking if the engine is
already running. The engine cranking can be
stopped by turning the ignition switch to the
ACCESSORY or LOCK position.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can
overheat and damage the cranking motor and
drain the battery. Waiting about 15 seconds
between each try, to allow the cranking motor to
cool down, will prevent damage due to
overheating.
