The power liftgate switch is on the driver
door. The vehicle must be in P (Park). The
taillamps flash when the power liftgate
moves.
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
