Pr
ess l on the bottom of the liftgate to
close.
Press any liftgate button, the touch pad, or b
on the remote key while the liftgate is moving
to stop it. Pressing any liftgate button or
pressing b twice quickly on the 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
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)
wh
ile 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 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.
Setting the Custom Opening Height
To change the position the liftgate stops at
when opening:
1. Select MAX or Custom 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.
