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.
Notice:If you open the liftgate without checking for
overhead obstructions such as a garage door,
you could damage the liftgate or the liftgate glass.
Always check to make sure the area above and
behind the liftgate is clear before opening it.
The power liftgate can be power opened and closed in
the following ways:

The liftgate can also be closed by pressing the power
liftgate button next to the liftgate latch. Press the button
a second time during liftgate operation to reverse that
operation.
The power liftgate may be temporarily disabled under
extreme temperatures, or under low battery conditions. If
this occurs, the liftgate can still be operated manually.If you shift the transmission out of PARK (P) while the
power function is in progress, the liftgate power function
will continue to completion. If you shift the transmission
out of PARK (P) and accelerate before the power
liftgate latches closed, the liftgate may reverse to the
open position. Cargo could fall out of the vehicle. Always
make sure the power liftgate is closed and latched
before you drive away.
If you power open the liftgate and the liftgate support
struts have lost pressure, the lights will ash and a
chime will sound. The liftgate will stay open temporarily,
then slowly close. See your dealer/retailer for service
before using the liftgate.
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 power liftgate operation can be used again. If the
liftgate encounters multiple obstacles on the same power
cycle, the power function will deactivate, and you
must manually open or close the liftgate. The LIFTGATE
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. Power Liftgate Button Near Liftgate Latch

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. Do not force the liftgate open or
closed during a power cycle.
Manual Operation of Power Liftgate
To change the liftgate to
manual operation, press
the switch on the
center console to the OFF
position.
With the power liftgate disabled and all of the doors
unlocked, the 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 to lower the liftgate
and close. The liftgate latch will power close. 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.
It is not recommended that you drive with the liftgate
open, however, if you must drive with the liftgate open,
the liftgate should be set to manual operation by
pressing the OFF switch on the center console.
The liftgate has an electric latch. If the battery is
disconnected or has low voltage, the liftgate will not
open. The liftgate will resume operation when the battery
is reconnected and charged.
If the battery is properly connected with adequate
voltage, the switch is not disabled, and the liftgate still
will not function, your vehicle should be taken to a
dealer/retailer for service.

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 one of the
following:
Press the lock button on the Remote Keyless Entry
(RKE) transmitter when any door is open.
The security light should come on and ash. When
the door is closed, the security light will stop
ashing and stay on solid and then go off after
approximately 30 seconds. The content theft
deterrent alarm is not armed until the security light
goes off.
If the delayed locking feature is active, the alarm
will not be activated until all doors are closed
and the security light goes off.
Press the lock button on the RKE transmitter when
the driver door is closed.
The security light will come on solid for
approximately 30 seconds and then go off. The
content theft deterrent alarm is not armed until the
security light goes off.
2-21

If a locked door is opened without using the key in the
driver’s door key cylinder or 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 the doors
are locked with the vehicle’s key or the manual door
lock. It activates only if you use the power door
lock switch with the door open or 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
To test the alarm:
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 5-100.
If the alarm does not sound or the vehicle’s headlamps
do not ash, see your dealer/retailer for service.
