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
to prevent the liftgate from opening
into overhead obstructions such as a
garage door or roof-mounted cargo.
The liftgate can be manually opened
all the way.
OFF : Opens manually only.
To power open or close the liftgate,
select MAX or 3/4 mode.
Press twice quickly on the RKE
transmitter until the liftgate
moves.
Press on the driver door. The
driver door must either be
unlocked or locked without the
security armed.
Press the touch pad on the
underside of the liftgate handle
after unlocking all doors. A locked
vehicle can be opened if the RKE
transmitter is within 1 m (3 ft) of
the touch pad.
KEYS, DOORS, AND WINDOWS
Press on the bottom of the
liftgate next to the pull cup to
close.
Press any liftgate button, or the touch
pad, or on the RKE transmitter
while the liftgate is moving to stop it.
Pressing any liftgate button again or
pressing twice 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.
