remote key can be used for all locks.
Remove the key by pressing the button on
the side of the remote key near the bottom
and pull the key out. Never pull the key out
without pressing the button.
If it becomes difficult to turn the key,
inspect the key blade for debris. Periodically,
clean with a brush or a pick.
See your dealer if a new remote key is
needed.
If locked out of the vehicle, seeRoadside
Assistance Program 0332. With an active OnStar or connected service
plan, an OnStar Advisor may remotely
unlock the vehicle. See
OnStar Overview
0 340.
Remote Key
See Radio Frequency Statement 0337.
If there is a decrease in the remote key
operating range:
.Check the distance. The remote key may
be too far from the vehicle.
.Check the location. Other vehicles or
objects may be blocking the signal.
.Check the remote key's battery. See
“Battery Replacement” later in this
section.
.If the remote key is still not working
correctly, see your dealer or a qualified
technician for service.
Remote Key Operation
The Keyless Access system allows for vehicle
entry when the remote key is within 1 m
(3 ft). See “Keyless Access Operation” later in
this section.
The remote key may work up to 60 m

20 Keys, Doors, and Windows
If equipped with a power liftgate, the switch
is on the driver door. The vehicle must be in
P (Park).
The modes are:
.MAX: Opens to maximum height.
.3/4: Opens to a reduced height that can
be set from 3/4 to fully open. Use to
prevent the liftgate from opening into
overhead obstructions such as a garage
door or roof-mounted cargo. The liftgate
can be manually opened all the way.
.OFF: Opens manually only.
To power open or close the liftgate, select
MAX or 3/4 mode.
.Pressbtwice quickly on the remote
key until the liftgate moves.
.Press8on the driver door. The driver
door must either be unlocked or locked
without the security armed.
.Press the touch pad in the liftgate handle
after unlocking all doors. The remote key
must be within 1 m (3 ft).
.Presslon the bottom of the liftgate.
Press any liftgate button or the touch pad
while the liftgate is moving to stop it.
Pressing again restarts the operation in the
reverse direction. The touch pad in the
liftgate handle cannot be used to close the
liftgate.
Caution
Manually forcing the liftgate to open or
close during a power cycle can damage
the vehicle. Allow the power cycle to
complete. The power liftgate may be temporarily
disabled under extreme low temperatures,
or after repeated power cycling over a short
period of time. If this occurs, the liftgate can
still be operated manually.
If the vehicle is shifted out of P (Park) while
the power function is in progress, the
liftgate will continue to completion. If the
vehicle is accelerated before the liftgate has
completed moving, the liftgate may stop or
reverse direction. Check for Driver
Information Center (DIC) messages and make
sure the liftgate is closed and latched before
driving.
Falling Liftgate Detection
If the power liftgate automatically closes
after a power opening cycle, it indicates that
the system is reacting to excess weight on
the liftgate or a possible support strut
failure. A repetitive chime will sound while
the falling liftgate detection feature is
operating. Remove any excess weight. If the
liftgate continues to automatically close
after opening, see your dealer for service
before using the power liftgate.
Interfering with the power liftgate motion
or manually closing the liftgate too quickly
after power opening may resemble a
support strut failure. This could also activate

26 Keys, Doors, and Windows
If the engine does not start and the security
light stays on, there is a problem with the
system. Turn the ignition off and try again.
If the ignition will not change from off to
on or ACC/ACCESSORY, and the remote key
appears to be undamaged, try another
remote key. Or, you may try placing the
remote key in the cupholder in the center
console. SeeRemote Key Operation 07.
If the vehicle will not start with the other
remote key, or with the remote key in the
cupholder, the vehicle needs service. If the
vehicle does start, the first remote key may
be faulty. See your dealer who can service
the theft-deterrent system and have a new
remote key programmed to the vehicle.
It is possible for the immobilizer system to
learn new or replacement remote keys. Up
to eight remote keys can be programmed to
the vehicle. To program additional remote
keys, see “Programming remote keys to the
Vehicle” underRemote Key Operation 07.
Do not leave the remote key or device that
disarms or deactivates the theft-deterrent
system in the vehicle.Exterior Mirrors
