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.
There are several ways to open and
close the power liftgate:
8
Press and hold
transmitter until the liftgate starts
moving.
8
Press on the overhead
console.
Press on the bottom of the
liftgate next to the latch to close.
Pressing a second time while the
liftgate is moving reverses the
direction.
To disable the power liftgate
function, press OFF on the liftgate
switch.
The power liftgate may be
temporarily disabled under extreme
temperatures, or under low battery
conditions. If this occurs, the liftgate
can still be operated manually.
If the transmission is shifted out of P
(Park) while the power function is in
progress, the liftgate power function
will continue to completion. If the
on the RKE
transmission is shifted out of P
(Park) and the vehicle accelerates
before the power liftgate latches
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 driving away.
If the liftgate is opened using power
operation and the liftgate support
struts have lost pressure, the turn
signals flash and a chime will
sound. The liftgate stays open
Keys, Doors, and Windows
temporarily, and then slowly closes.
See a dealer 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
and a message will display in the
Driver Information Center (DIC).
See Object Detection System
Messages on page 5 39. After
removing the obstructions, the
liftgate will resume normal power
operation.
