key is equipped with a motion sensor. When
starting the vehicle, if the remote key has
been idle for a while, move the remote key
slightly and try starting the vehicle. When
starting the vehicle, if the remote key
battery is depleted or there is signal
interference, the DIC may display NO

occur, resulting in severe injury or death.
Seek medical attention immediately if a
battery is swallowed.
{Warning
To avoid personal injury, do not touch
metal surfaces on the remote key when
it has been exposed to extreme heat.
These surfaces can be hot to the touch at

Free-Turning Locks
The door key lock cylinder turns freely when
either the wrong key is used, or the correct
key is not fully inserted. The free-turning
door lock feature prevents the lock from
being forced open. To reset the lock, turn it
to the vertical position with the correct key
fully inserted. Remove the key and insert it
again. If this does not reset the lock, turn
the key halfway around in the cylinder and
repeat the reset procedure.

reconnected and charged.
Always close the liftgate before driving.
Power Liftgate Operation
{Warning
You or others could be injured if caught

liftgate as it is opening and closing.
Caution
Driving with an open and unsecured
liftgate may result in damage to the
power liftgate components.

Keys, Doors, and Windows 23
If equipped, 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 remote
key until the liftgate moves.
.Press8on the driver door. The driver
door must either be unlocked or locked
without the security armed.

remote key 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 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

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 0306.
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 accessory
mode and a valid remote key 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 remote keys
matched to an immobilizer control unit in
the vehicle. Only a correctly matched
remote key will start the vehicle. If the
remote key is ever damaged, the vehicle
may not start.
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, and the remote key appears to be
undamaged, try another remote key. Or, try
placing the remote key into the remote key
pocket located in the center console. See
Starting the Vehicle With a Low remote key
Battery under
Remote Key Operation 010.
If the ignition mode will not change with
the other remote key or with a remote key
in the remote key pocket, your vehicle
needs service. If the ignition does change
modes, 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.
