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 which 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.
Pinch sensors are on the side
edges of the liftgate. If an object is
caught between the liftgate and the
vehicle and presses against a
sensor, the liftgate will reverse
direction and open fully. The liftgate
will remain open until it is activated
again or closed manually.
Setting the 3/4 Mode
To change the position the liftgate
stops at when opening:
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.
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 switch. Manually
adjust the liftgate position if
needed.
3. Press and hold

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 transmitter
leaves the vehicle.
The immobilization system is
disarmed when the ignition is turned
on or in ACC/ACCESSORY and a
valid Remote Keyless Entry (RKE)
transmitter is 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 ignition will not change from
off to on or ACC/ACCESSORY, and
the RKE transmitter appears to be
undamaged, try another transmitter.
Or, you may try placing the
transmitter in the cupholder in the
center console.
If the ignition mode will not change
with the other transmitter or with the
transmitter in the 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 to
the vehicle. To program additional
transmitters, see “Programming
Transmitters to the Vehicle” under
Remote Keyless Entry (RKE)
System Operation 0 8.
Do not leave the transmitter or
device that disarms or deactivates
the theft-deterrent system in the
vehicle.
