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
The power liftgate will automatically
close if the support strut has lost
pressure. See your dealer for
service before using the power
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.
Pinch sensors are located 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 stop at the first
position at which the liftgate can
hold open. 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
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
liftgate next to the latch until
the turn signals flash and a
beep sounds to indicate that
the new setting is recorded.
When power opened with the 3/4
mode selected, the liftgate stops at
the new set position.
If there is no audible and visual
feedback when setting the
intermediate stop position, the
liftgate height is being set below the
3/4 open height minimum
(approximately 1.5 m or 5 ft). The
liftgate cannot be set below that
minimum and the new setting will
not be recorded.
Manual Operation of Power
Liftgate
To change the liftgate to manual
operation, turn the mode switch to
