GMC Terrain: Doors / Setting the 3/4 Mode
To change the position the liftgate
stops at when opening:
- Select MAX or 3/4 mode and
power open the liftgate.
- Stop the liftgate movement at
the desired height by pressing
any liftgate switch. Manually
adjust the liftgate position if
needed.
- Press and hold
next to the
pull cup on the bottom of the
liftgate until the turn signals
flash and a beep sounds. This
indicates the setting has been
recorded.
The liftgate cannot be set below a
minimum programmable height.
If there is no light flash or sound,
then the height adjustment may be
too low.
If the liftgate encounters an obstacle
during a power open or close cycle,
the liftgate will automatically reverse
direction and move a short distance
away from the obstacle...
Select OFF to manually operate the
liftgate.
Caution
Attempting to move the liftgate
too quickly and with excessive
force may result in damage to the
vehicle...
