reverse direction. The touch pad in the
liftgate handle cannot be used to close the
liftgate.
Caution
Manually forcing the liftgate to open or
close during a power cycle can damage
the vehicle. Allow the power cycle to
complete.
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) 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. Check for Driver
Information Center (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, a warning
chime may 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 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 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
switch. Manually adjust the liftgate
position if needed.
3. Press and hold
lat the bottom 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.
