Power Liftgate Operation
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.
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
remote key 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 remote key
is within 1 m (3 ft) of the
touch pad.
