20 Keys, Doors, and Windows
Press a
ny liftgate button, the touch pad, or b
o
n 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.
When stopping the gate at low heights it may
partially reopen.
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. 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. Remove any excess weight. A repetitive
chime will sound while the falling liftgate
detection feature is operating. 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,
ma
nually 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.
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 l on the bottom edge of
the liftgate 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.
