Position the release button on
the buckle so that the seat belt
could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster, move it to the
height that is right for you. See
“Shoulder Belt Height Adjuster”
later in this section for
instructions on use and
important safety information.
5. To make the lap part tight, pullup on the shoulder belt.
To unlatch the belt, push the button
on the buckle. The belt should return
to its stowed position.
Always stow the seat belt slowly. If the
seat belt webbing returns quickly to
the stowed position, the retractor may
lock and cannot be pulled out. If this
happens, pull the seat belt straight out
firmly to unlock the webbing, and
then release it. If the webbing is still
locked in the retractor, see your
dealer.

Before a door is closed, be sure the
seat belt is out of the way. If a door is
slammed against a seat belt, damage
can occur to both the seat belt and
the vehicle.
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height
adjuster for the driver and front
outboard passenger seating positions.
Adjust the height so that the shoulder
portion of the belt is on the shoulder
and not falling off of it. The belt
should be close to, but not contacting,
the neck. Improper shoulder belt
height adjustment could reduce the
effectiveness of the seat belt in a
crash. SeeHow to Wear Seat Belts
Properly 053.
Press and hold the release button
while raising or lowering the height
adjuster to the desired position.
After the height adjuster is set to the
desired position, try to move it down
without pressing the release button to
make sure it has locked into position.
Seat Belt Pretensioners
This vehicle has seat belt
pretensioners for the front outboard
occupants. Although the seat belt
pretensioners cannot be seen, they are
part of the seat belt assembly. They
can help tighten the seat belts during
the early stages of a moderate to
severe frontal, near frontal, or rear crash if the threshold conditions for
pretensioner activation are met. Seat
belt pretensioners can also help
tighten the seat belts in a side crash
or a rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash, the
pretensioners and probably other
parts of the vehicle's seat belt system
will need to be replaced. See
Replacing
Seat Belt System Parts after a Crash

Do not sit on the outboard seat belt
while entering or exiting the vehicle or
at any time while sitting in the seat.
Sitting on the seat belt can damage
the webbing and hardware.
Rear Seat Belt Comfort Guides
Rear seat belt comfort guides may
provide added seat belt comfort for
older children who have outgrown
booster seats and for some adults.
When installed on a shoulder belt, the
comfort guide positions the shoulder
belt away from the neck and head.
The comfort guides for the second row
outboard seating positions of this
vehicle are provided in a package in

Warning (Continued)
airbag must be kept clear. Do not
put anything between an occupant
and an airbag, and do not attach or
put anything on the steering wheel
hub or on or near any other airbag
covering.
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.
SeeAirbag System 060. 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 or near
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, rear
impacts, or many side impacts.
In addition, the vehicle has advanced
technology frontal airbags. Advanced
technology frontal airbags adjust the
restraint according to crash severity.
Knee airbags are designed to inflate in
moderate to severe frontal or
near-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. Seat-mounted
side impact airbags are not designed
to inflate in frontal impacts, near
frontal impacts, rollovers, or rear
impacts. A seat-mounted side impact
airbag is designed to inflate on the
side of the vehicle that is struck.
Roof-rail airbags are designed to
inflate in moderate to severe side
crashes depending on the location of
the impact. In addition, these roof-rail
airbags are designed to inflate during
a rollover or in a severe frontal
impact. Roof-rail airbags are not
designed to inflate in rear impacts.
Both roof-rail airbags will inflate when

{Warning
When an airbag inflates, there may
be dust in the air. This dust could
cause breathing problems for
people with a history of asthma or
other breathing trouble. To avoid
this, everyone in the vehicle should
get out as soon as it is safe to do
so. If you have breathing problems
but cannot get out of the vehicle
after an airbag inflates, then get
fresh air by opening a window or a
door. If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the fuel
system after the airbags inflate. The
feature may also activate, without
airbag inflation, after an event that
exceeds a predetermined threshold.
After turning the ignition off and then
on again, the fuel system will return to normal operation; the doors can be
locked, the interior lamps can be
turned off, and the hazard warning
flashers can be turned off using the
controls for those features. If any of
these systems are damaged in the
crash they may not operate as normal.
{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 0347 and
Event Data Recorders 0348.
. Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.

3. Remove any additional itemsfrom 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) 086 or
Securing Child Restraints (With the
Seat Belt in the Front Seat) 088.
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
0 41.
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 materialfrom 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 and have 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 070 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.

only one person at a time.
{Warning
Never allow a child to wear the seat
belt with the shoulder belt behind
their back. A child can be seriously
injured by not wearing the
lap-shoulder belt properly. In a(Continued)
Warning (Continued)
crash, the child would not be
restrained by the shoulder belt. The
child could move too far forward
increasing the chance of head and
neck injury. The child might also
slide under the lap belt. The belt
force would then be applied right
on the abdomen. That could cause
serious or fatal injuries. The
shoulder belt should go over the
shoulder and across the chest.
Infants and Young Children
Everyone in a vehicle needs
protection! This includes infants and
all other children. Neither the distance
traveled 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
strangled if a shoulder belt is
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 a child’s neck. If the
shoulder belt is locked and(Continued)

Securing a Child Restraint
Designed for the LATCH System
{Warning
A child could be seriously injured or
killed in a crash if the child
restraint is not properly attached to
the vehicle using either the LATCH
anchors or the vehicle seat belt.
Follow the instructions that came
with the child restraint and the
instructions in this manual.
{Warning
To reduce the risk of serious or
fatal injuries during a crash, do not
attach more than one child
restraint to a single anchor.
Attaching more than one child
restraint to a single anchor could
cause the anchor or attachment to
come loose or even break during a
crash. A child or others could be
injured.
{Warning
Children can be seriously injured or
strangled if a shoulder belt is
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 a child’s neck. If the
shoulder belt is locked and
tightened around a child’s neck, the
only way to loosen the belt is to
cut it.
Buckle any unused seat belts
behind the child restraint so
children cannot reach them. Pull
the shoulder belt all the way out of
the retractor to set the lock, and
tighten the belt behind the child
restraint after the child restraint
has been installed.
Caution
Do not let the LATCH attachments
rub against the vehicle’s seat belts.
This may damage these parts.
If necessary, move buckled seat
belts to avoid rubbing the LATCH
attachments.
Do not fold the rear seatback when
the seat is occupied. Do not fold the
empty rear seat with a seat belt
buckled. This could damage the
seat belt or the seat. Unbuckle and
return the seat belt to its stowed
position, before folding the seat.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint 077.
1. Attach and tighten the lower attachments to the lower
anchors. If the child restraint
does not have lower attachments
or the desired seating position
does not have lower anchors,
secure the child restraint with
the top tether and the seat belt.

Replacing LATCH System
Parts After a Crash
{Warning
A crash can damage the LATCH
system in the vehicle. A damaged
LATCH system may not properly
secure the child restraint, resulting
in serious injury or even death in a
crash. To help make sure the
LATCH system is working properly
(Continued)
Warning (Continued)
after a crash, see your dealer to
have the system inspected and any
necessary replacements made as
soon as possible.
If the vehicle has the LATCH system
and it was being used during a crash,
new LATCH system parts may be
needed.
New parts and repairs may be
necessary even if the LATCH system
was not being used at the time of the
crash.
Securing Child Restraints
(With the Seat Belt in the
Rear Seat)
When securing a child restraint with
the seat belts in a rear seat position,
study the instructions that came with
the child restraint to make sure it is
compatible with this vehicle.
If the child restraint has the LATCH
system, see Lower Anchors and Tethers
for Children (LATCH System) 078 for

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13527548) - 2020 - CRC - 9/5/19
SEATS AND RESTRAINTS 87
how and where to install the child
restraint using LATCH. If a child
restraint is secured in the vehicle
using a seat belt and it uses a top
tether, seeLower Anchors and Tethers
for Children (LATCH System) 078 for
top tether anchor locations.
Do not secure a child seat in a
position without a top tether anchor if
a national or local law requires that
the top tether be anchored, or if the
instructions that come with the child
restraint say that the top tether must
be anchored.
In Canada, the law requires that
forward-facing child restraints have a
top tether, and that the tether be
attached.
If the child restraint or vehicle seat
position does not have the LATCH
system, you will be using the seat belt
to secure the child restraint. Be sure
to follow the instructions that came
with the child restraint.
If more than one child restraint needs
to be installed in the rear seat, be sure
to read Where to Put the Restraint 077. 1. Put the child restraint on
the seat.
If the head restraint interferes
with the proper installation of
the child restraint, the head
restraint may be removed. See
"Head Restraint Removal and
Reinstallation" under Lower
Anchors and Tethers for Children
(LATCH System) 078.
2. Pick up the latch plate, and run the lap and shoulder portions of
the vehicle seat belt through or
around the child restraint. The
child restraint instructions will
show you how.3. Push the latch plate into thebuckle until it clicks.
Position the release button on
the buckle, away from the child
restraint, so that the seat belt
could be quickly unbuckled if
necessary.
4. Pull the shoulder belt all the way
out of the retractor to set the
lock. When the retractor lock is
set, the belt can be tightened but
not pulled out of the retractor.
