Power Liftgate Operation
{Warning
You or others could be injured if
caught in the path of the power
liftgate. Make sure there is no one
in the way of the liftgate as it is
opening and closing.
Caution
Driving with an open and
unsecured liftgate may result in
damage to the power liftgate
components.
The power liftgate switch is on the
driver door. The vehicle must be in
P (Park).
The modes are:
MAX : Opens to maximum height. 3/4 :
Opens to a reduced height that
can be set from 3/4 to fully open. Use

.Presslon the bottom of the
liftgate next to the pull cup to close.
Press any liftgate button, or the touch
pad, or
bon the RKE transmitter
while the liftgate is moving to stop it.
Pressing any liftgate button again or
pressing
btwice quickly on the RKE
transmitter 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.
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,
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. 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

3. Press and hold
lnext to the pull
cup on 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.
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.

limits the manual closing speed to
protect the components.
Hands-Free Operation

operated with a kicking motion under
the left corner of the rear bumper at
the location of the projected logo. The RKE transmitter must be within
