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.

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-14574701) -
2021 - CRC - 2/8/21
22 KEYS, DOORS, AND WINDOWS
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. This 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.
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
lon 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.
Manual Operation
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.
