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.

programmable height. If there is no light
flash or sound, then the height adjustment
may be too low.

See “Manual Liftgate” at the beginning of
this section.
Caution

smooth motion and moderate speed. The
system includes a feature which limits the
manual closing speed to protect the
components.
