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

Caution
Manually forcing the liftgate to open or
close during a power cycle can damage
the vehicle. Allow the power cycle to
complete. The power liftgate may be temporarily
disabled under extreme low temperatures,
or after repeated power cycling over a short
period of time. If this occurs, the liftgate can
still be operated manually.
If the vehicle is shifted out of P (Park) while
the power function is in progress, the
liftgate will continue to completion. If the
vehicle is accelerated before the liftgate has
completed moving, the liftgate may stop or
reverse direction. Check for Driver
Information Center (DIC) messages and make
sure the liftgate is closed and latched before
driving.
Falling Liftgate Detection
If the power liftgate automatically closes
after a power opening cycle, it indicates that
the system is reacting to excess weight on
the liftgate or a possible support strut
failure. A repetitive chime will sound while
the falling liftgate detection feature is
operating. Remove any excess weight. If the
liftgate continues to automatically close
after opening, see your dealer for service
before using the power liftgate.
Interfering with the power liftgate motion
or manually closing the liftgate too quickly
after power opening may resemble a
support strut failure. This could also activate
