GMC ACADIA 2017 Owner's Manual page 44

Press on the bottom of the
liftgate next to the pull cup to
close.
Press any liftgate button or the
touch pad while the liftgate is
moving to stop it. Pressing again
restarts the operation in the reverse
direction. The touch pad on the
liftgate handle cannot be used to
close 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
DIC messages and make sure the
liftgate is closed and latched before
driving.
Falling Liftgate Detection
The power liftgate will automatically
close if the support strut has lost
pressure. See your dealer for
service before using the power
liftgate.
Obstacle Detection Features
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. After
removing the obstruction, the power
liftgate operation can be used again.
If the liftgate encounters multiple
obstacles on the same power cycle,
the power function will deactivate.
After removing the obstructions,
manually close the liftgate which will
allow normal power operation
functions to resume.
Keys, Doors, and Windows
If the vehicle is locked while the
liftgate is closing, and an obstacle is
encountered that prevents the
liftgate from completely closing, the
horn will sound as an alert that the
liftgate did not close.
Pinch sensors are on the side
edges of the liftgate. If an object is
caught between the liftgate and the
vehicle and presses against this
sensor, the liftgate will reverse
direction and open fully. The liftgate
will remain open until it is activated
again or closed manually.
Setting the 3/4 Mode
To change the position the liftgate
stops at when opening:
1. Select MAX or 3/4 mode and
power open the liftgate.
2. Stop the liftgate movement at
the desired height by pressing
any liftgate switch. Manually
adjust the liftgate position if
needed.
