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.

Seats and Restraints 65
Seat Belt Care
Keep belts clean and dry.
Seat belts should be properly
cared for and maintained.
Seat belt hardware should be
kept dry and free of dust or
debris. As necessary, exterior
hard surfaces and seat belt
webbing may be lightly
cleaned with mild soap and
water. Ensure there is not
excessive dust or debris in the
mechanism. If dust or debris
exists in the system please
see the dealer. Parts may
need to be replaced to ensure
proper functionality of the
system.
{Warning
Do not bleach or dye seat
belt webbing. It may severely
weaken the webbing. In a
crash, they might not be
able to provide adequate
protection. Clean and rinse
seat belt webbing only with(Continued)
Warning (Continued)
mild soap and lukewarm
water. Allow the webbing
to dry.
Replacing Seat Belt
System Parts after a
Crash
{Warning
A crash can damage the
seat belt system in the
vehicle. A damaged seat belt
system may not properly
protect the person using it,
resulting in serious injury or
even death in a crash. To
help make sure the seat belt
systems are working
properly after a crash, have
them inspected and any
necessary replacements
made as soon as possible.
After a minor crash,
replacement of seat belts may
not be necessary. But the seat belt assemblies that were
used during any crash may
have been stressed or
damaged. See your dealer to
have the seat belt assemblies
inspected or replaced.
New parts and repairs may be
necessary even if the seat belt
system was not being used at
the time of the crash.
Have the seat belt
pretensioners checked if the
vehicle has been in a crash,
or if the airbag readiness light
stays on after you start the
vehicle or while you are
driving. See Airbag Readiness
Light
0123.
Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the
driver
.A frontal airbag for the front
outboard passenger
.A knee airbag for the driver.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -

Seats and Restraints 67
{Warning
Because airbags inflate with
great force and faster than
the blink of an eye, anyone
who is up against, or very
close to, any airbag when it
inflates can be seriously
injured or killed. Do not sit
unnecessarily close to any
airbag, as you would be if
sitting on the edge of the
seat or leaning forward.
Seat belts help keep you in
position before and during a
crash. Always wear a seat
belt, even with airbags. The
driver should sit as far back
as possible while still
maintaining control of the
vehicle. The seat belts and
the front outboard
passenger airbags are most
effective when you are
sitting well back and upright
in the seat with both feet on
the floor.(Continued)
Warning (Continued)
Occupants should not lean
on or sleep against the door
or side windows in seating
positions with seat-mounted
side impact airbags and/or
roof-rail airbags.
{Warning
Children who are up against,
or very close to, any airbag
when it inflates can be
seriously injured or killed.
Always secure children
properly in the vehicle. To
read how, see Older
Children079 or
Infants and Young Children
0 81.
There is an airbag readiness
light on the instrument cluster,
which shows the airbag
symbol.
The system checks the airbag
electrical system for
malfunctions. The light tells
you if there is an electrical
problem. See Airbag
Readiness Light 0123.
Where Are the
Airbags?
The driver frontal airbag is in
the center of the steering
wheel.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/6/22
72 Seats and Restraints
{Warning
A crash severe enough to
inflate the airbags may have
also damaged important
functions in the vehicle, such
as the fuel system, brake
and steering systems, etc.
Even if the vehicle appears
to be drivable after a
moderate crash, there may
be concealed damage that
could make it difficult to
safely operate the vehicle.
Use caution if you should
attempt to restart the
engine after a crash has
occurred.
In many crashes severe
enough to inflate the airbag,
windshields are broken by
vehicle deformation. Additional
windshield breakage may also
occur from the front outboard
passenger airbag.
.Airbags are designed to
inflate only once. After an
airbag inflates, you will need
some new parts for the
airbag system. If you do not
get them, the airbag system
will not be there to help
protect you in another crash.
A new system will include
airbag modules and possibly
other parts. The service
manual for the vehicle
covers the need to replace
other parts.
.The vehicle has a crash
sensing and diagnostic
module which records
information after a crash.
See Vehicle Data Recording
and Privacy 0498 and
Event Data Recorders 0499.
.Let only qualified technicians
work on the airbag system.
Improper service can mean
that an airbag system will
not work properly. See your
dealer for service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position.
The passenger airbag status
indicator will light on the
overhead console when the
vehicle is started.
The words ON and OFF, and
the symbols for on and off, will
be visible during the system
check. When the system check
is complete, either the word
ON or OFF, and the symbol for
on or off, will be visible. See
Passenger Airbag Status
Indicator 0124.
The passenger sensing
system turns off the front
outboard passenger frontal
airbag and knee airbag under

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/6/22
74 Seats and Restraints
.The system determines an
infant is present in a child
restraint.
.A front outboard passenger
takes his/her weight off of
the seat for a period of time.
When the passenger sensing
system has turned off the
front outboard passenger
frontal airbag and knee airbag,
the OFF indicator will light and
stay lit as a reminder that the
airbags are off. See Passenger
Airbag Status Indicator 0124.
The passenger sensing
system is designed to turn on
the front outboard passenger
frontal airbag and knee airbag,
anytime the system senses
that a person of adult size is
sitting properly in the front
outboard passenger seat.
When the passenger sensing
system has allowed the airbag
to be enabled, the ON
indicator will light and stay lit
as a reminder that the airbags
are active. For some children, including
children in child restraints, and
for very small adults, the
passenger sensing system
may or may not turn off the
front outboard passenger
frontal airbag and knee airbag,
depending upon the person's
seating posture and body
build. Everyone in the vehicle
who has outgrown child
restraints should wear a seat
belt properly
—whether or not
there is an airbag for that
person.
{Warning
If the airbag readiness light
ever comes on and stays on,
it means that something may
be wrong with the airbag
system. To help avoid injury
to yourself or others, have
the vehicle serviced right
away. See Airbag Readiness
Light 0123 for more
information, including
important safety
information.
If the On Indicator Is Lit
for a Child Restraint
The passenger sensing
system is designed to turn off
the front outboard passenger
frontal airbag and knee airbag,
if the system determines that
an infant is present in a child
restraint. If a child restraint
has been installed and the ON
indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such
as blankets, cushions, seat
covers, seat heaters,
or seat massagers.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/6/22
78 Seats and Restraints
In addition, the vehicle has a
passenger sensing system for
the front outboard passenger
position, which includes
sensors that are part of the
passenger seat. The
passenger sensing system
may not operate properly if
the original seat trim is
replaced with non-GM covers,
upholstery, or trim; or with GM
covers, upholstery, or trim
designed for a different
vehicle. Any object, such as an
aftermarket seat heater or a
comfort-enhancing pad or
device, installed under or on
top of the seat fabric, could
also interfere with the
operation of the passenger
sensing system. This could
either prevent proper
deployment of the passenger
airbag(s) or prevent the
passenger sensing system
from properly turning off the
passenger airbag(s). See
Passenger Sensing System
072. If the vehicle has rollover
roof-rail airbags, see Different
Size Tires and Wheels
0439
for additional important
information.
If the vehicle must be modified
because you have a disability
and have questions about
whether the modifications will
affect the vehicle's airbag
system, or if you have
questions about whether the
airbag system will be affected
if the vehicle is modified for
any other reason, call
Customer Assistance. See
Customer Assistance Offices
0 487.
Airbag System Check
The airbag system does not
need regularly scheduled
maintenance or replacement.
Make sure the airbag
readiness light is working. See
Airbag Readiness Light 0123.
Caution
If an airbag covering is
damaged, opened, or broken,
the airbag may not work
properly. Do not open or
break the airbag coverings.
If there are any opened or
broken airbag coverings,
have the airbag covering
and/or airbag module
replaced. For the location of
the airbags, see Where Are
the Airbags? 067. See your
dealer for service.
