not touch any of the circuitry on
the transmitter. Static from your
body could damage the
transmitter.
Caution
Always replace the battery with
the correct type. Replacing the
battery with an incorrect type
could potentially create a risk of
battery explosion. Dispose of
used batteries according to
instructions and local laws. Do
not attempt to burn, crush, or cut
the used battery.
Replace the battery in the
transmitter soon if the DIC displays
REPLACE BATTERY IN

Power Liftgate Operation
Warning
{
You or others could be injured if
caught in the path of the power
liftgate. Make sure there is no one
in the way of the liftgate as it is
opening and closing.
Caution
Driving with an open and
unsecured liftgate may result in
damage to the power liftgate
components.
If equipped, the power liftgate
switch is on the driver door. The
vehicle must be in P (Park). The
taillamps flash when the power
liftgate moves.
The modes are:
.
MAX: Opens to maximum
height.
GMC Acadia/Acadia Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-13687875) - 2020 - CRC - 5/29/19
.
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 can be manually opened
all the way.
.
OFF: Opens manually only.
To power open or close the liftgate,
select MAX or 3/4 mode.

Caution
Manually forcing the liftgate to

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
the falling liftgate detection feature.
Allow the liftgate to complete its
operation and wait a few seconds
before manually closing the 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.
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 a
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 button. Manually
adjust the liftgate position if
needed.
3. Press and hold
pull cup on the outside 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.

Caution
Attempting to move the liftgate
too quickly and with excessive
force may result in damage to the
vehicle.
Operate the liftgate manually with a
smooth motion and moderate
speed. The system includes a
feature which limits the manual
closing speed to protect the
components.
The hands-free feature can be
customized. See Vehicle
Personalization 0 149. Choose from
the following:
On-Open and Close : The kicking
motion is activated to both open and
close the liftgate.

The RKE transmitter must be within
1 m (3 ft) of the rear bumper to
operate the power liftgate
hands-free.
The hands-free feature will not work
while the liftgate is moving. To stop
the liftgate while in motion use one
of the liftgate buttons.
To operate, move your foot in a
forward kicking motion under the left
side of the rear bumper, at the
location of the projected logo, then
Kick Zone

pull it back. Then step back. The
kick must come within 14 cm (6 in)
of the rear bumper to activate.
Caution
Splashing water may cause the
liftgate to open. Keep the RKE
transmitter away from the rear
bumper detection area or turn the
liftgate mode to OFF when
cleaning or working near the rear
bumper to avoid accidental
opening.
.
Do not sweep your foot side
to side.
.
Do not keep your foot under the
bumper; the liftgate will not
activate.

after it has been out of range for at
least 20 seconds.
If an RKE transmitter is again
detected within approximately 2 m

hands-free operation has been
detected, the one-minute timer will
be reset.
