Keys, Doors, and Windows
Do not manually force the liftgate to
open or close during a power cycle.
The power liftgate may be
temporarily disabled in extremely
low temperatures, or after repeated
power cycling over a short period of
time. If this occurs, the liftgate can
still be operated manually. Select
OFF on the liftgate switch.
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. Make sure
the liftgate is closed and latched
before driving.
If the power liftgate support strut
has lost pressure, the turn signals
will flash and a chime will sound
while the liftgate automatically
closes. See your dealer for service
before using the power 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 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
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
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
l
next to the
latch 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.
