The liftgate door and window should be closed before driving your
vehicle. If not, possible damage may occur to the liftgate door lift
cylinders and attaching hardware.
Make sure that the liftgate door and/or window are closed to
prevent exhaust fumes from being drawn into the vehicle. This
will also prevent passengers and cargo from falling out. If you must
drive with the liftgate door or window open, keep the vents open so
outside air comes into the vehicle.
