belts are the only restraint.
See When Should an Airbag
Inflate?072.
Wearing your seat belt
during a crash helps reduce
your chance of hitting things
inside the vehicle or being
ejected from it. Airbags are
“supplemental restraints” to
the seat belts. Everyone in
the vehicle should wear a
seat belt properly, whether
or not there is an airbag for
that person.
{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 (Continued)
Warning (Continued)
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.
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
Children082 or
Infants and Young Children
0 83.
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 0127 for
more information.

Warning (Continued)
Do not use seat accessories
that block the inflation path
of a seat-mounted side
impact airbag.
Never secure anything to
the roof of a vehicle with
roof-rail airbags by routing a
rope or tie‐down through
any door or window opening.
If you do, the path of an
inflating roof-rail airbag will
be blocked.
When Should an
Airbag Inflate?
This vehicle is equipped with
airbags. See Airbag System
069. Airbags are designed to
inflate if the impact exceeds
the specific airbag system's
deployment threshold.
Deployment thresholds are
used to predict how severe a
crash is likely to be in time for
the airbags to inflate and help
restrain the occupants. The vehicle has electronic sensors
that help the airbag system
determine the severity of the
impact. Deployment
thresholds can vary with
specific vehicle design.
Frontal airbags are designed
to inflate in moderate to
severe frontal crashes to help
reduce the potential for
severe injuries, mainly to the
driver's or front outboard
passenger's head and chest.
Whether the frontal airbags
will or should inflate is not
based primarily on how fast
the vehicle is traveling.
It depends on what is hit, the
direction of the impact, and
how quickly the vehicle
slows down.
Frontal airbags may inflate at
different crash speeds
depending on whether the
vehicle hits an object straight
on or at an angle, and whether
the object is fixed or moving,
rigid or deformable, narrow
or wide.Frontal airbags are not
intended to inflate during
vehicle rollovers, in rear
impacts, or in many side
impacts.
In addition, the vehicle has
advanced technology frontal
airbags. Advanced technology
frontal airbags adjust the
restraint according to either
crash severity or occupant
interaction.
Knee airbags are designed to
inflate in moderate to severe
frontal impacts. Knee airbags
are not designed to inflate
during vehicle rollovers, in rear
impacts, or in many side
impacts.
Seat-mounted side impact
airbags are designed to inflate
in moderate to severe side
crashes depending on the
location of the impact. These
airbags may also inflate in
some moderate to severe
frontal impacts. Seat-mounted
side impact airbags are not
designed to inflate in rollovers

occupant and determine if the
front outboard passenger
frontal 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.
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(Continued)
Warning (Continued)
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 passenger frontal
airbag, no system is fail-safe.
No one can guarantee that
an airbag will not deploy
under some unusual
circumstance, even though
the airbag is turned 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(Continued)
Warning (Continued)
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 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, the OFF

indicator will light and stay lit
as a reminder that the airbag
is off. See Passenger Airbag
Status Indicator0128.
The passenger sensing
system is designed to turn on
the front outboard passenger
frontal 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 airbag
is 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, 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 0127 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 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) 097
or Securing Child
Restraints (With the Seat
Belt in the Front Seat)
0 99.
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
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 Restraints 048.
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:
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,

nor the age and size of the
traveler changes the need, for
everyone, to use safety
restraints. In fact, the law in
every state in the United
States and in every Canadian
province says children up to
some age must be restrained
while in a vehicle.
{Warning
Children can be seriously
injured or killed if the
shoulder belt is worn behind
their back, under their legs,
or wrapped around their
neck. The shoulder belt can
tighten but cannot be
loosened if it is locked. The
shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when
the shoulder belt is allowed
to go all the way back into
the retractor, but it cannot
do this if it is wrapped
around the child. Never
leave children unattended in(Continued)
Warning (Continued)
a vehicle and never allow
children to improperly wear,
or play with, the seat belts.
Every time infants and young
children ride in vehicles, they
should have the protection
provided by appropriate child
restraints. Neither the
vehicle's seat belt system nor
its airbag system is designed
for them.
Children who are not
restrained properly can strike
other people, or can be
thrown out of the vehicle.
{Warning
Never hold an infant or a
child while riding in a vehicle.
Due to crash forces, an
infant or a child will become
so heavy it is not possible to
hold it during a crash. For
example, in a crash at only
40 km/h (25 mph), a (Continued)
Warning (Continued)
5.5 kg (12 lb) infant will
suddenly become a
110 kg (240 lb) force on a
person's arms. An infant or
child should be secured in an
appropriate child restraint.
{Warning
Children who are up against,
or very close to, any airbag
when it inflates can be
seriously injured or killed.
Never put a rear-facing child(Continued)

Warning (Continued)
restraint in the front
outboard seat. Secure a
rear-facing child restraint in
a rear seat. It is also better
to secure a forward-facing
child restraint in a rear seat.
If you must secure a
forward-facing child
restraint in the front
outboard seat, always move
the front passenger seat as
far back as it will go.
Child restraints are devices
used to restrain, seat,
or position children in the
vehicle and are sometimes
called child seats or car seats.
There are three basic types
of child restraints:
.Forward-facing child
restraints
.Rear-facing child restraints
.Belt-positioning booster
seats
The proper child restraint for
your child depends on their
size, weight, and age, and also
on whether the child restraint
is compatible with the vehicle
in which it will be used.
For each type of child
restraint, there are many
different models available.
When purchasing a child
restraint, be sure it is
designed to be used in a
motor vehicle and is designed
by a genuine child restraint
manufacturer. If it is, the child
restraint will have a label saying that it meets federal
motor vehicle safety
standards.
The instruction manual that is
provided with the child
restraint states the weight
and height limitations for that
particular child restraint. In
addition, there are many kinds
of child restraints available for
children with special needs.
{Warning
To reduce the risk of neck
and head injury in a crash,
infants and toddlers should
be secured in a rear-facing
child restraint until age two,
or until they reach the
maximum height and weight
limits of their child restraint.
{Warning
A young child's hip bones
are still so small that the
vehicle seat belt may not

Warning (Continued)
remain low on the hip bones,
as it should. Instead, it may
settle up around the child's
abdomen. In a crash, the belt
would apply force on a body
area that is unprotected by
any bony structure. This
alone could cause serious or
fatal injuries. To reduce the
risk of serious or fatal
injuries during a crash,
young children should
always be secured in an
appropriate child restraint.
Child Restraint
Systems
Rear-Facing Infant Restraint
A rear-facing child restraint
provides restraint with the
seating surface against the
back of the infant.
The harness system holds the
infant in place and, in a crash,
acts to keep the infant
positioned in the restraint.
Forward-Facing Child Restraint
A forward-facing child
restraint provides restraint for
the child's body with the
harness.

16406251) - 2023 - CRC - 3/25/22
Seats and Restraints 87
Booster Seats
A belt-positioning booster
seat is used for children who
have outgrown their
forward-facing child restraint.
Boosters are designed to
improve the fit of the vehicle's
seat belt system until the child
is large enough for the vehicle
seat belts to fit properly
without a booster seat. See
the seat belt fit test in Older
Children 082.
Securing an Add-On Child
Restraint in the Vehicle
{Warning
A child can be seriously
injured or killed in a crash if
the child restraint is not
properly secured in the
vehicle. Secure the child
restraint properly in the
vehicle using the vehicle
seat belt or LATCH system,
following the instructions
that came with that child
restraint and the
instructions in this manual.
To help reduce the chance of
injury, the child restraint must
be secured in the vehicle. Child
restraints must be secured in
vehicle seats by lap belts or
the lap belt portion of a
lap-shoulder belt, or by the
LATCH system. See Lower
Anchors and Tethers for
Children (LATCH System) 090
for more information. Never
use a seat belt extender when installing a child restraint.
Never use non-regulated
aftermarket anchors or
attachments to secure a child
restraint. Children can be
endangered in a crash if the
child restraint is not properly
secured in the vehicle.
When securing an add-on child
restraint, refer to the
following:
1. Instruction labels provided on the child restraint
2. Instruction manual provided with the child
restraint
3. This vehicle owner's manual
The child restraint instructions
are important, so if they are
not available, obtain a
replacement copy from the
manufacturer.
Keep in mind that an
unsecured child restraint can
move around in a collision or
sudden stop and injure people
in the vehicle. Be sure to

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16406251) - 2023 - CRC - 3/25/22
88 Seats and Restraints
properly secure any child
restraint in the vehicle—even
when no child is in it.
In some areas Certified Child
Passenger Safety Technicians
(CPSTs) are available to
inspect and demonstrate how
to correctly use and install
child restraints. In the U.S.,
refer to the National Highway
Traffic Safety Administration
(NHTSA) website to locate the
nearest child safety seat
inspection station. For CPST
availability in Canada, check
with Transport Canada or the
Provincial Ministry of
Transportation office.

properly following the
instructions that came with
that child restraint.
Where to Put the
Restraint
According to accident
statistics, children and infants
are safer when properly
restrained in an appropriate
child restraint secured in a
rear seating position.
Whenever possible, children
aged 12 and under should be
secured in a rear seating
position.
Never put a rear-facing child
restraint in the front. This is
because the risk to the
rear-facing child is so great if
the airbag deploys.
{Warning
A child in a rear-facing child
restraint can be seriously
injured or killed if the front
passenger 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 front passenger airbag
inflates and the passenger
seat is in a forward position.
Even if the passenger
sensing system has turned
off the front passenger
frontal airbag, no system is
fail-safe. No one can
guarantee that an airbag will
not deploy under some
unusual circumstance, even
though it is turned off.(Continued)
