But if a seat belt is not long enough,
your dealer will order you an extender.
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 belt height
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, haveit 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
0 113.
Keep seat belts clean and dry. See Seat
Belt Care 060.
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.
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.

SEATS AND RESTRAINTS 61
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. SeeAirbag
Readiness Light 0114.
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
.A seat-mounted side impact airbag
for the driver
.A seat-mounted side impact airbag
for the front outboard passenger
.A roof-rail airbag for the driver and
for the second and third row
passengers seated directly behind
the driver
.A roof-rail airbag for the front
outboard passenger and for the
second and third row passengers
seated directly behind the front
outboard passenger
All vehicle airbags have the word
AIRBAG on the trim or on a label near
the deployment opening.
For frontal airbags, the word AIRBAG
is on the center of the steering wheel
for the driver and on the instrument
panel for the front outboard
passenger.
For knee airbags, the word AIRBAG is
on the lower part of the instrument
panel.
For seat-mounted side impact airbags,
the word AIRBAG is on the side of the
seatback or side of the seat closest to
the door.
For roof-rail airbags, the word AIRBAG
is on the ceiling or trim. Airbags are designed to supplement
the protection provided by seat belts.
Even though today's airbags are also
designed to help reduce the risk of
injury from the force of an inflating
bag, all airbags must inflate very
quickly to do their job.
Here are the most important things to
know about the airbag system:
{Warning
You can be severely injured or
killed in a crash if you are not
wearing your seat belt, even with
airbags. Airbags are designed to
work with seat belts, not replace
them. Also, airbags are not designed
to inflate in every crash. In some
crashes seat belts are the only
restraint. See
When Should an
Airbag Inflate? 064.
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 (Continued)

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 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, seeOlder Children 072 or
Infants and Young Children 073.
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
0114 for more
information.
Where Are the Airbags?
The driver frontal airbag is in the
center of the steering wheel.

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 061. 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, 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 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. These airbags
are also designed to inflate in some
moderate to severe frontal or
near-frontal impacts that could result
in the occupant moving toward the
side of the vehicle. Seat-mounted side
impact airbags are not designed to
inflate in 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

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-14574701) -
2021 - CRC - 2/8/21
SEATS AND RESTRAINTS 65
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
either side of the vehicle is struck,
if the sensing system predicts that the
vehicle is about to roll over on its
side, or in a severe frontal impact.
In any particular crash, no one can
say whether an airbag should have
inflated simply because of the vehicle
damage or repair costs.
What Makes an Airbag
Inflate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inflator. Gas from the inflator fills the
airbag causing the bag to break out of
the cover. The inflator, the airbag, and
related hardware are all part of the
airbag module.
For airbag locations, seeWhere Are the
Airbags? 062.
How Does an Airbag
Restrain?
In moderate to severe frontal or near
frontal collisions, even belted
occupants can contact the steering
wheel or the instrument panel. In
moderate to severe side collisions,
even belted occupants can contact the
inside of the vehicle.
Airbags supplement the protection
provided by seat belts by distributing
the force of the impact more evenly
over the occupant's body.
Rollover capable roof-rail airbags are
designed to help contain the head and
chest of occupants in the outboard
seating positions in the first, second,
and third rows. The rollover capable
roof-rail airbags are designed to help
reduce the risk of full or partial
ejection in rollover events, although
no system can prevent all such
ejections.
But airbags would not help in many
types of collisions, primarily because
the occupant's motion is not toward
those airbags. See When Should an
Airbag Inflate? 064. Airbags should never be regarded as
anything more than a supplement to
seat belts.What Will You See after an
Airbag Inflates?
After frontal, knee, and seat-mounted
side impact airbags inflate, they
quickly deflate, so quickly that some
people may not even realize the
airbags inflated. Roof-rail airbags may
still be at least partially inflated for
some time after they inflate. Some
components of the airbag module may
be hot for several minutes. For
location of the airbags, see
Where Are
the Airbags? 062.
The parts of the airbag that come into
contact with you may be warm, but
not too hot to touch. There may be
some smoke and dust coming from
the vents in the deflated airbags.
Airbag inflation does not prevent the
driver from seeing out of the
windshield or being able to steer the
vehicle, nor does it prevent people
from leaving the vehicle.

66 SEATS AND RESTRAINTS
{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
0 408 and
Event Data Recorders 0408.
.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.

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-14574701) -
2021 - CRC - 2/8/21
SEATS AND RESTRAINTS 67
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. SeePassenger
Airbag Status Indicator 0114.
The passenger sensing system turns
off the front outboard passenger
frontal 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
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 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.
(Continued)
Warning (Continued)
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 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.

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-14574701) -

.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 Indicator
0 114.
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 0114 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) 087 or
Securing Child Restraints (With the
Seat Belt in the Front Seat) 089.
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

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-14574701) -

SEATS AND RESTRAINTS 69
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. SeeHead
Restraints 040.
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, 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.
