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.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:
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 DIC.
Immobilizer
See Radio Frequency Statement 0350.
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.
