Keys, Doors, and Windows 9
The key, inside the remote key,
can be used for all locks.
To remove the key, press the
button on the side of the
remote key, near the bottom,
and pull the key out. Never pull
the key out without pressing
the button.
If it becomes difficult to turn
the key, inspect the key blade
for debris. Periodically, clean
with a brush or a pick.
See your dealer if a new key is
needed.
Contact Roadside Service if
locked out of the vehicle. See
Roadside Assistance Program
0470.
With an active OnStar or
connected service plan, an
OnStar Advisor may remotely
unlock the vehicle. See OnStar
Overview 0482.
Remote Key
See Radio Frequency
Statement 0477.
If there is a decrease in the
key operating range:
.Check the distance. The key
may be too far from the
vehicle.
.Check the location. Other
vehicles or objects may be
blocking the signal.
.Check the key battery. See
“Battery Replacement” later
in this section.
.If the key is still not working
correctly, see your dealer or
a qualified technician for
service.
Remote Key
Operation
The Keyless Access system
allows for vehicle entry when
the remote key is within 1 m
(3 ft). See “Keyless Access
Operation” following.
The remote key functions may
work up to 60 m (197 ft) away
from the vehicle.
Other conditions can impact
the performance of the
remote key. See Remote Key
0 9.

.Presslon the bottom of
the liftgate to close.
Press any liftgate button, the
touch pad, or
bon the
remote key while the liftgate is
moving to stop it. Pressing any
liftgate button or pressing
b
twice quickly on the remote
key again restarts the
operation in the reverse
direction. Pressing the touch
pad on the liftgate handle will
restart the motion, but only in
the opening direction.
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 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.

Keys, Doors, and Windows 35
Inclination and Intrusion
Sensors Disable Switch
It is recommended that the
inclination and intrusion
sensors be deactivated if pets
are left in the vehicle or if the
vehicle is being transported.
With the vehicle turned off,
press
oin the overhead
console. The indicator light will
come on momentarily,
indicating that the sensor has
been disabled until the next
time the alarm system is
armed.
Steering Column Lock
If equipped, the steering
column lock is a
theft-deterrent device. This
feature locks the steering
column when the vehicle is
turned off and the driver door
is opened, or when the driver
door is opened and then the
vehicle is turned off. The
steering column unlocks when
the vehicle is turned on. The Driver Information Center
(DIC) may display one of these
messages:
.A message to service the
steering column lock
indicates that an issue has
been detected with the
column lock feature and the
vehicle should be serviced.
.A message that the steering
column is locked indicates
that the engine is running,
but the steering column is
still locked. It is normal for
the column to be locked
during a remote start, but
the column should unlock
after the brake pedal is
pressed and the vehicle is
started. No message will
display during a remote
start.
.A message that the steering
wheel must be turned and
the vehicle must be started
again indicates that the
column lock mechanism is
bound, the column locking
device was unable to unlock
the steering column, and thevehicle did not start. If this
happens, immediately turn
the steering wheel from side
to side to unbind the column
lock. If this does not unlock
the steering column, turn the
vehicle off and open the
driver door to reset the
system. Then turn the
vehicle on and immediately
turn the steering wheel side
to side for about 15 seconds.
In some cases, it may take
significant force to unbind
the column.
To keep the steering column
from binding, straighten the
front wheels before turning
off the vehicle.
Immobilizer
See Radio Frequency
Statement 0477.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-16405819) -
2023 - CRC - 3/23/22
36 Keys, Doors, and Windows
The system does not have to
be manually armed or
disarmed.
The vehicle is automatically
immobilized when the vehicle
is turned off.
The immobilization system is
disarmed when the ignition is
on or in accessory mode and a
valid remote key is present in
the vehicle.
The security light, in the
instrument cluster, comes on if
there is a problem with arming
or disarming the
theft-deterrent system.
The system has one or more
remote keys matched to an
immobilizer control unit in your
vehicle. Only a correctly
matched remote key will startthe vehicle. If the remote key
is ever damaged, you may not
be able to start your vehicle.
When trying to start the
vehicle, the security light may
come on briefly when the
ignition is turned on.
If the engine does not start
and the security light stays on,
there is a problem with the
system. Turn the ignition off
and try again.
If the vehicle will not change
ignition modes (accessory
mode, on, off), and the remote
key appears to be undamaged,
try another remote key. Or,
you may try placing the
remote key in the remote key
pocket located in the center
console. See Remote Key
Operation
09.
If the ignition mode will not
change with the other remote
key or in the remote key
pocket, your vehicle needs
service. If the ignition does
change modes, the first
remote key may be faulty. See your dealer who can service
the theft-deterrent system
and have a new remote key
programmed to the vehicle.
It is possible for the
immobilizer system to learn
new or replacement remote
keys. Up to eight remote keys
can be programmed for the
vehicle. To program additional
remote keys, see
“Programming Remote Keys to
the Vehicle”
under Remote
Key Operation 09.
Do not leave the remote key
or device that disarms or
deactivates the
theft-deterrent system in the
vehicle.
