Seat Belt Extender
If the vehicle's seat belt will
fasten around you, you should
use it.
But if a seat belt is not long
enough, your dealer will order
you an extender. Only a GM
dealer issued extender should
be used. When you go in to
order it, take the heaviest coat
you will wear, so the extender
will be long enough for you. To
help avoid personal injury, do
not let someone else use it,
and use it only for the seat it is
made to fit. The extender has
been designed for adults.
Never use it for securing child
restraints. For more
information on the proper use
and fit of seat belt extenders
see the instruction sheet that
comes with the extender.
Safety System Check
Periodically check the seat
belt reminder, seat belts,
buckles, latch plates,
retractors, shoulder beltheight adjusters (if equipped),
and seat belt anchorages to
make sure they are all in
working order. Look for any
other loose or damaged seat
belt system parts that might
keep a seat belt system from
performing properly. See your
dealer to have it repaired.
Torn, frayed, or twisted seat
belts may not protect you in a
crash. Torn or frayed seat
belts can rip apart under
impact forces. If a belt is torn
or frayed, have it replaced
immediately. If a belt is
twisted, it may be possible to
untwist by reversing the latch
plate on the webbing. If the
twist cannot be corrected, ask
your dealer to fix it.
Make sure the seat belt
reminder light is working. See
Seat Belt Reminders
0123.
Keep seat belts clean and dry.
See Seat Belt Care 064.
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
mild soap and lukewarm
water. Allow the webbing
to dry.

{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

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 0124.
Where Are the
Airbags?
The driver frontal airbag is in
the center of the steering
wheel.
The front outboard passenger
frontal airbag is in the
passenger side instrument
panel.
The driver knee airbag is
below the steering column.
The front outboard passenger
knee airbag is below the
glove box.

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 Privacy0448 and
Event Data Recorders 0449.
.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 0125.
The passenger sensing
system turns off the front
outboard passenger frontal
airbag and knee airbag under certain conditions. No other
airbag is affected by the
passenger sensing system.
The passenger sensing
system works with sensors
that are part of the front
outboard passenger seat and
seat belt. The sensors are
designed to detect the
presence of a properly seated
occupant and determine if the
front outboard passenger
frontal airbag and knee airbag
should be allowed to inflate
or not.
According to accident
statistics, children are safer
when properly secured in a
rear seat in the correct child
restraint for their weight
and size.
Whenever possible, children
aged 12 and under should be
secured in a rear seating
position.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
Seats and Restraints 73
Never put a rear-facing child
seat in the front. This is
because the risk to the
rear-facing child is so great,
if the airbag inflates.
{Warning
A child in a rear-facing child
restraint can be seriously
injured or killed if the
passenger frontal airbag
inflates. This is because the
back of the rear-facing child
restraint would be very
close to the inflating airbag.
A child in a forward-facing
child restraint can be
seriously injured or killed if
the passenger frontal airbag
inflates and the passenger
seat is in a forward position.
Even if the passenger
sensing system has turned
off the front outboard
passenger airbag(s), no
system is fail-safe. No one
can guarantee that an(Continued)
Warning (Continued)
airbag will not deploy under
some unusual circumstance,
even though the airbag(s)
are off.
Never put a rear-facing child
restraint in the front seat,
even if the airbag is off.
If securing a forward-facing
child restraint in the front
outboard passenger seat,
always move the seat as far
back as it will go. It is better
to secure child restraints in
the rear seat. Consider
using another vehicle to
transport the child when a
rear seat is not available.
The passenger sensing
system is designed to turn off
the front outboard passenger
frontal airbag and knee
airbag if:
.The front outboard
passenger seat is
unoccupied.
.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.
.There is a critical problem
with the airbag system or
the passenger sensing
system.
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 0125.
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

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
74 Seats and Restraints
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

Warning (Continued)
away. See Airbag Readiness
Light0124 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. 4. Reinstall the child restraint
following the directions
provided by the child
restraint manufacturer and
refer to Securing Child
Restraints (With the Seat
Belt in the Rear Seat) 095
or Securing Child
Restraints (With the Seat
Belt in the Front Seat)
0 98.
Make sure the seat belt
retractor is locked by
pulling the shoulder belt all
the way out of the
retractor when installing
the child restraint, even if
the child restraint is
equipped with a seat belt
lock off. When the
retractor lock is set, the
belt can be tightened but
not pulled out of the
retractor.
5. If, after reinstalling the child restraint and
restarting the vehicle, the
ON indicator is still lit, turn
the vehicle off. Then
slightly recline the vehicle

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
Seats and Restraints 75
seatback and adjust the
seat cushion, if adjustable,
to make sure that the
vehicle seatback is not
pushing the child restraint
into the seat cushion.
Also make sure the child
restraint is not trapped
under the vehicle head
restraint. If this happens,
adjust the head restraint.
See Head Restraints045.
6. Restart the vehicle.
The passenger sensing
system may or may not turn
off the airbag for a child in a
child restraint depending upon
the child’s size. It is better to
secure the child restraint in a
rear seat. Never put a
rear-facing child restraint in
the front seat, even if the ON
indicator is not lit.If the Off Indicator Is Lit
for an Adult-Sized
Occupant
If a person of adult size is
sitting in the front outboard
passenger seat, but the OFF
indicator is lit, it could be
because that person is not
sitting properly in the seat or
that the child restraint locking
feature is engaged. Use the
following steps to allow the
system to detect that person
and enable the front outboard
passenger frontal airbag and
knee airbag: 1. Turn the vehicle off.
2. Remove any additional
material from the seat,
such as blankets, cushions,
seat covers, seat heaters,
or seat massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat,
centered on the seat
cushion, with legs
comfortably extended.
5. If the shoulder portion of the belt is pulled out all the
way, the child restraint
locking feature will be
engaged. This may
unintentionally cause the
passenger sensing system
to turn the airbag off for
some adult-sized
occupants. If this happens,
unbuckle the belt, let the
belt go back all the way,
and then buckle the belt
again without pulling the
belt out all the way.

6. Restart the vehicle andhave the person remain in
this position for two to
three minutes after the ON
indicator is lit.
{Warning
If the front outboard
passenger airbag is turned
off for an adult-sized
occupant, the airbag will not
be able to inflate and help
protect that person in a
crash, resulting in an
increased risk of serious
injury or even death. An
adult-sized occupant should
not ride in the front
outboard passenger seat,
if the passenger airbag OFF
indicator is lit.
Additional Factors
Affecting System
Operation
Seat belts help keep the
passenger in position on the
seat during vehicle maneuvers and braking, which helps the
passenger sensing system
maintain the passenger airbag
status. See
“Seat Belts” and
“Child Restraints” in the Index
for additional information
about the importance of
proper restraint use.
A thick layer of additional
material, such as a blanket or
cushion, or aftermarket
equipment such as seat
covers, seat heaters, and seat
massagers can affect how well
the passenger sensing system
operates. We recommend that
you not use seat covers or
other aftermarket equipment
except when approved by GM
for your specific vehicle. See
Adding Equipment to the
Airbag-Equipped Vehicle 077
for more information about
modifications that can affect
how the system operates.
The ON indicator may be lit if
an object, such as a briefcase,
handbag, grocery bag, laptop,
or other electronic device, is put on an unoccupied seat.
If this is not desired, remove
the object from the seat.
{Warning
Stowing articles under the
passenger seat or between
the passenger seat cushion
and seatback may interfere
with the proper operation of
the passenger sensing
system.
Servicing the
Airbag-Equipped
Vehicle
Airbags affect how the vehicle
should be serviced. There are
parts of the airbag system in
several places around the
vehicle. Your dealer and the
service manual have
information about servicing
the vehicle and the airbag
system. To purchase a service
manual, see Publication
Ordering Information
0445.

Child Restraints
Older Children
Older children who have
outgrown booster seats
should wear the vehicle’s seat
belts. Refer to How to Wear
Seat Belts Properly058.
The manufacturer instructions
that come with the booster
seat state the weight and
height limitations for that
booster. Use a booster seat
with a lap-shoulder belt until
the child passes the fit test
below:
.Sit all the way back on the
seat. Do the knees bend at
the seat edge? If yes,
continue. If no, return to the
booster seat.
.Buckle the lap-shoulder belt.
Does the shoulder belt rest
on the shoulder? If yes,
continue. If no, try using the
rear seat belt comfort guide,
if available. See “Rear Seat
Belt Comfort Guides” under
Lap-Shoulder Belt 060. If a
comfort guide is not
available, or if the shoulder
belt still does not rest on the
shoulder, then return to the
booster seat.
.Does the lap belt fit low and
snug on the hips, touching
the thighs? If yes, continue.
If no, return to the
booster seat.
.Can proper seat belt fit be
maintained for the length of
the trip? If yes, continue.
If no, return to the
booster seat. Q: What is the proper way to
wear seat belts?
A: An older child should wear a
lap-shoulder belt and get
the additional restraint a
shoulder belt can provide.
The shoulder belt should
not cross the face or neck.
The lap belt should fit
snugly below the hips, just
touching the top of the
thighs. This applies belt
force to the child's pelvic
bones in a crash. It should
never be worn over the
abdomen, which could cause
severe or even fatal internal
injuries in a crash.
Also see “Rear Seat Belt
Comfort Guides” under
Lap-Shoulder Belt 060.
According to accident
statistics, children are safer
when properly restrained in a
rear seating position.
In a crash, children who are
not buckled up can strike
other people who are buckled
up, or can be thrown out of
