Falling Liftgate Detection
I
f 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,
m
anually 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 this
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 switch.
Manually adjust the liftgate position
if needed.
3.
P
ress and hold l to the left of the latch
at 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.
Caution
Attempting to move the liftgate too quickly
and with excessive force may result in
damage to the vehicle.
Operate the liftgate manually with asmooth
motion and moderate speed. The system
includes afeature which limits the manual
closing speed to protect the components.
