continue to completion. If the
vehicle is shifted out of P (Park)
and accelerated before the power
liftgate latch closes, 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
driving away.
If the power liftgate is used and
the liftgate support struts have lost
pressure, the taillamps will flash and
a chime will sound. The liftgate will
stay open temporarily, and then
slowly close. See a dealer for
service before using the liftgate if
this occurs.
Obstacle Detection Features
A warning chime will sound and
the liftgate will automatically
reverse direction to the full closed
or open position if an obstacle is
encountered during a power open or
close cycle. After removing the
obstacle the liftgate will resume
normal operation.
If more obstacles are encountered
on the same power cycle, the power
function deactivates, and the liftgate
must be opened or closed manually.
A message displays on the Driver
Information Center (DIC) to indicate
that the liftgate is open. See Driver
Information Center (DIC) (With DIC
Buttons) on page 5‑24 or Driver
Information Center (DIC) (Without
DIC Buttons) on page 5‑29. After
removing the obstacles, manually
open the liftgate fully or close and
latch the liftgate. The liftgate will
resume normal power operation.
The vehicle has pinch sensors
located on the side edges of the
liftgate. If an object is caught
between the liftgate and the body of
the vehicle and presses against a
sensor, the liftgate will reverse
direction and open fully. The liftgate
will remain open until it is activated
again or closed manually. Do not
force the liftgate open or closed
during a power cycle.
Manual Operation of Power
Liftgate
To change the liftgate to manual
operation, press OFF on the power
liftgate switch. A message displays
on the DIC indicating manual
operation mode. See Driver
Information Center (DIC) (With DIC
Buttons) on page 5‑24 or Driver
Information Center (DIC) (Without
DIC Buttons) on page 5‑29.
