Warning (Continued)
.If the vehicle is equipped with a
power liftgate, disable the power
liftgate function.
See Engine Exhaust 0226.
Caution
To avoid damage to the liftgate or
liftgate glass, make sure the area
above and behind the liftgate is
clear before opening it.
Power Liftgate Operation
{Warning
You or others could be injured if
caught in the path of the power
liftgate. Make sure there is no one
in the way of the liftgate as it is
opening and closing.
Caution
Driving with an open and
unsecured liftgate may result in
damage to the power liftgate
components.
The power liftgate 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 RKE
transmitter 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 on the
underside of the liftgate handle
after unlocking all doors. A locked
vehicle can be opened if the RKE
transmitter is within 1 m (3 ft) of
the touch pad.

.Presslon the bottom of the
liftgate next to the pull cup to close.
Press any liftgate button, or the touch
pad, or
bon the RKE transmitter
while the liftgate is moving to stop it.
Pressing any liftgate button again or
pressing
btwice quickly on the RKE
transmitter restarts the operation in
the reverse direction. Pressing the
touch pad on the liftgate handle will
restart the motion, but only in the
opening direction.
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 the
falling liftgate detection feature. Allow
the liftgate to complete its operation
and wait a few seconds before
manually closing the liftgate.
Obstacle Detection Features
If the liftgate encounters an obstacle
during a power open or close cycle,
the liftgate will automatically reverse
direction and move a short distance
away from the obstacle. After
removing the obstruction, the power
liftgate operation can be used again.
If the liftgate encounters multiple
obstacles on the same power cycle,
the power function will deactivate.
After removing the obstructions,

manually close the liftgate. This will
allow normal power operation
functions to resume.
If the vehicle is locked while the
liftgate is closing, and an obstacle is
encountered that prevents the liftgate
from completely closing, the horn will
sound as an alert that the liftgate did
not close.
Setting the 3/4 Mode
To change the position the liftgate
stops at when opening:1. Select MAX or 3/4 mode and power open the liftgate.
2. Stop the liftgate movement at the desired height by pressing any
liftgate button. Manually adjust the
liftgate position if needed.
3. Press and hold
lnext to the pull
cup on the bottom of the liftgate
until the turn signals flash and a
beep sounds. This indicates the
setting has been recorded. The liftgate cannot be set below a
minimum programmable height.
If there is no light flash or sound,
then the height adjustment may be
too low.
Manual Operation
Select OFF to manually operate the
liftgate.
Caution
Attempting to move the liftgate too
quickly and with excessive force
may result in damage to the
vehicle.
Operate the liftgate manually with a
smooth motion and moderate speed.
The system includes a feature which
limits the manual closing speed to
protect the components.
Hands-Free Operation
If equipped, the liftgate may be
operated with a kicking motion under
the left corner of the rear bumper at
the location of the projected logo. The RKE transmitter must be within
1 m (3 ft) of the rear bumper to
operate the power liftgate hands-free.
The hands-free feature will not work
while the liftgate is moving. To stop
the liftgate while in motion use one of
the liftgate switches.

How to Detect a Tamper
Condition
IfKis pressed and the horn chirps
and the lights flash three times, the
alarm was activated while the alarm
system was armed.
If the alarm system has been
activated, a message will appear on
the DIC.
Immobilizer
See Radio Frequency Statement 0383.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the vehicle is
turned off.
The immobilization system is
disarmed when the ignition is on or in
ACC/ACCESSORY and a valid
transmitter is present in the vehicle.
The security light, in the instrument
cluster, comes on if there is a problem
with arming or disarming the
theft-deterrent system.
The system has one or more RKE
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched RKE
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
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 vehicle will not change ignition
modes (ACC/ACCESSORY, on, off), and
the RKE transmitter appears to be undamaged, try another transmitter.
Or, you may try placing the
transmitter in the front cupholder
located in the center console. See
Remote Keyless Entry (RKE) System
Operation
07.
If the ignition mode will not change
with the other transmitter or in the
front cupholder, your vehicle needs
service. If the ignition does change
modes, the first transmitter may be
faulty. See your dealer who can service
the theft-deterrent system and have a
new RKE transmitter programmed to
the vehicle.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
transmitters, see “Programming
Transmitters to the Vehicle ”under
Remote Keyless Entry (RKE) System
Operation 07.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.
