liftgate adjacent to the latch to close
the liftgate.
Pressing any button, or the
touchpad switch while the liftgate is
moving stops it. Pressing the button
or RKE switch again reverses the
direction. The touch pad switch will
stop the liftgate from moving. There
is a minimum distance that the
power liftgate must already be open
for the system to hold it open.
If movement is stopped below that
minimum the liftgate closes. Do not force the liftgate open or
closed during a power cycle.
The power liftgate may be
temporarily disabled under extreme
temperatures or low battery
conditions. If this occurs, the liftgate
can still be operated manually.
If you shift the transmission out of
P (Park) while the power function is
in progress, the liftgate power
function will continue to completion.
If you shift the transmission out of
P (Park) and accelerate before the
power liftgate latch is closed, the
liftgate may reverse to the open
position. Cargo could fall out of the
vehicle. Always make sure the
power liftgate is closed and latched
before you drive away.
If you power open the liftgate and
the liftgate support struts have lost
pressure, the turn signals flash and
a chime sounds. The liftgate stays
open temporarily, then slowly
closes. See your dealer/retailer for
service before using the liftgate.
Obstacle Detection Features
If the liftgate encounters an obstacle
during a power open or close cycle,
a warning chime will sound and the
liftgate will automatically reverse
direction to the full closed or open
position. 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.
The
“Manually Close Power Liftgate”
warning message in the Driver
Information Center (DIC) will
display. After removing the
obstructions, the liftgate will resume
normal power operation.
Your vehicle has pinch sensors
located on the side edges of the
liftgate. If an object is caught
between the liftgate and the body
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.
