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.

Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious
enough to cause an expensive
repair or replacement. Paying
attention to the warning lights
and gauges could prevent
injury.
Some warning lights come on
briefly when the engine is
started to indicate they are
working. When one of the
warning lights comes on and
stays on while driving, or when
one of the gauges shows
there may be a problem, check
the section that explains what
to do. Waiting to do repairs
can be costly and even
dangerous.

If the driver seat belt is
buckled, neither the light nor
the chime comes on.
Front Passenger Seat Belt
Reminder Light
The vehicle may have a front
passenger seat belt reminder
light near the passenger
airbag status indicator. See
Passenger Sensing System
072.
When the vehicle is started,
this light flashes and a chime
may come on to remind
passengers to fasten their
seat belt.
Then the light stays on solid
until the belt is buckled. This
cycle continues several times
if the front passenger remains
or becomes unbuckled while
the vehicle is moving. If the front passenger seat
belt is buckled, neither the
chime nor the light comes on.
The front passenger seat belt
reminder light and chime may
come on if an object is put on
the seat such as a briefcase,
handbag, grocery bag, laptop,
or other electronic device. To
turn off the reminder light
and/or chime, remove the
object from the seat or buckle
the seat belt.
Airbag Readiness
Light
This light shows if there is an
electrical problem with the
airbag system. It is located in
the instrument cluster. The
system check includes the
airbag sensor(s), the
passenger sensing system,
the pretensioners, the airbag
modules, the wiring, and the
crash sensing and diagnostic
module. For more information
on the airbag system, see
Airbag System
065.
The airbag readiness light
comes on for several seconds
when the vehicle is started.
If the light does not come on
then, have it fixed immediately.
{Warning
If the airbag readiness light
stays on after the vehicle is
started or comes on while
driving, it means the airbag
system might not be working
properly. The airbags in the
vehicle might not inflate in a
crash, or they could even
inflate without a crash. To
help avoid injury, have the
vehicle serviced right away.
If there is a problem with the
airbag system, a Driver
Information Center (DIC)
message may also come on.

072 for important safety
information. The overhead
console has a passenger
airbag status indicator.
When the vehicle is started,
the passenger airbag status
indicator will light ON and OFF,
and the symbols for on and
off, for several seconds as a
system check. Then, after
several more seconds, the
status indicator will light either
ON or OFF, and either the
symbol for on or off, to let you
know the status of the front
outboard passenger frontal
airbag and knee airbag. If the word ON, and the on
symbol, is lit on the passenger
airbag status indicator, it
means that the front outboard
passenger frontal airbag and
knee airbag are allowed to
inflate.
If the word OFF, and the off
symbol, is lit on the passenger
airbag status indicator, it
means that the passenger
sensing system has turned off
the front outboard passenger
frontal airbag and knee airbag.
