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

direction and move a short distance
away from the obstacle...
Select OFF to manually operate the
liftgate.
