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 distanceaway 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:
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 outside 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. See “Manual Liftgate” at the
beginning of this section.
