Driving with an open and
unsecured liftgate may result in
damage to the power liftgate
components.
If equipped, the power liftgate
switch is on the overhead console.
The vehicle must be in P (Park).
The modes are:
MAX : Opens to maximum height.

open or close during a power
cycle can damage the vehicle.
Allow the power cycle to
complete.
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

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.

Mexico-13566622) - 2020 - CRC - 4/15/19
30 Keys, Doors, and Windows
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 theliftgate 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 a
sensor, the liftgate will reverse
direction and stop at a partially open
position. 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 button. Manually
adjust the liftgate position if
needed.
3. Press and hold
lon 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.
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.
