is used for the driver door and
glove box.
To remove the mechanical key,
press the button on the side
of the remote key near the
bottom, and pull the
mechanical key out. Never pull
the mechanical 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 pick.
See your dealer if a new
mechanical key is needed.
Contact Roadside Assistance
if locked out of the vehicle.
See Roadside Assistance
Program0489.
With an active OnStar or
connected service plan, an
OnStar Advisor may remotely
unlock the vehicle. See OnStar
Overview 0501.Remote Key
See Radio Frequency
Statement 0496.
If there is a decrease in the
remote key operating range:
.Check the distance. The
remote key may be too far
from the vehicle.
.Check the location. Other
vehicles or objects may be
blocking the signal.
.Check the remote key
battery. See “Battery

Keys, Doors, and Windows 31
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 unlockafter 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 the
vehicle 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
0496.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.
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
turned on or to accessory
mode and a valid remote key is
present in the vehicle.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/6/22
32 Keys, Doors, and Windows
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 the
vehicle. Only a correctly
matched remote key will start
the 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.
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 backup
location. See Remote Key
Operation
09.
If the ignition modes will not
change with the other remote
key or in the backup location,
the vehicle needs service.
If the ignition does change
modes, the first remote key
may be faulty. See your dealer.
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.Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make
things, like other vehicles,
look farther away than they
really are. If you cut too
sharply into the right lane,
you could hit a vehicle on
the right. Check the inside
mirror or glance over your
shoulder before changing
lanes.
The passenger side mirror is
convex shaped. A convex
mirror's surface is curved so
more can be seen from the
driver seat.

than they are. Check the
outside mirrors or glance
over your shoulder when
making lane changes or

injury, death, or vehicle
damage.Troubleshooting

turn off the display.
.Dirt, snow, or other debris
blocks the camera lens.
Clean the lens with a soft
damp cloth.
.The camera’s mounting on
the vehicle has been
damaged, and/or the
position or the mounting
angle of the camera has
changed.
