Safety Belt Care
Keep belts clean and dry.
{WARNING
Do not bleach or dye safety belts.
It may severely weaken them. In
a crash, they might not be able to
provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.
Replacing Safety Belt
System Parts after a
Crash
{WARNING
A crash can damage the safety
belt system in the vehicle.
A damaged safety 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
safety belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.
After a minor crash, replacement of
safety belts may not be necessary.
But the safety belt assemblies that
were used during any crash may
have been stressed or damaged. See your dealer to have the safety
belt assemblies inspected or
replaced.
New parts and repairs may be
necessary even if the safety belt
system was not being used at the
time of the crash.
Have the safety 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. See
Airbag
Readiness Light on page 5‑10.

Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the driver.
.A frontal airbag for the right front
passenger.
.A seat-mounted side impact
airbag for the driver.
.A seat-mounted side impact
airbag for the right front
passenger.
.A roof-rail airbag for the driver
and the passenger seated
directly behind the driver.
.A roof-rail airbag for the right
front passenger and the
passenger seated directly
behind the right front passenger.
All of the airbags in the vehicle will
have the word AIRBAG embossed
in the trim or on an attached label
near the deployment opening. For frontal airbags, the word
AIRBAG will appear on the middle
part of the steering wheel for the
driver and on the instrument panel
for the right front passenger.
With seat-mounted side impact
airbags, the word AIRBAG will
appear on the side of the seatback
closest to the door.
With roof-rail airbags, the word
AIRBAG will appear along the trim.
Airbags are designed to supplement
the protection provided by safety
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 safety belt, even
with airbags. Airbags are
designed to work with safety
belts, not replace them. Also,
airbags are not designed to inflate
in every crash. In some crashes
safety belts are the only restraint.
See
When Should an Airbag
Inflate? on page 3‑22.
Wearing your safety belt during a
crash helps reduce the chance of
hitting things inside the vehicle or
being ejected from it. Airbags are
“supplemental restraints” to the
safety belts. Everyone in the
vehicle should wear a safety belt
properly, whether or not there is
an airbag for that person.
Black plate (20,1)GMC Terrain/Terrain Denali Owner Manual - 2013 - crc 1st edition - 5/8/12
3-20 Seats and Restraints
{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. Safety belts help keep
you in position before and during
a crash. Always wear a safety
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
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. Airbags plus
lap-shoulder belts offer protection
for adults and older children, but
not for young children and infants.
Neither the vehicle's safety belt
system nor its airbag system is
designed for them. Young
children and infants need the
protection that a child restraint
system can provide. Always
secure children properly in the
vehicle. To read how, seeOlder
Children on page 3‑33 orInfants
and Young Children on
page 3‑35.
There is an airbag readiness light
on the instrument panel 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 on page 5‑10 for
more information.
Black plate (24,1)GMC Terrain/Terrain Denali Owner Manual - 2013 - crc 1st edition - 5/8/12
3-24 Seats and Restraints
determined by the location and
severity of the side impact. In a
rollover event, roof-rail airbag
deployment is determined by the
direction of the roll.
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 location, seeWhere Are
the Airbags? on page 3‑21.
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 safety belts. Frontal
airbags distribute the force of the
impact more evenly over the
occupant's upper body, stopping the
occupant more gradually. Seat‐
mounted side impact and roof-rail
airbags distribute the force of the
impact more evenly over the
occupant's upper 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 and second 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? on
page 3‑22 for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See after
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag 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? on page 3‑21.
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

Improper service can mean that
an airbag system will not work
properly. See your dealer for

Passenger Sensing
System
The vehicle has a passenger
sensing system for the right front
passenger position. The passenger
airbag status indicator will be visible
on the overhead console when the
vehicle is started.
United States
Canada and Mexico
The words ON and OFF, or the
symbol for on and off, are visible
during the system check. If you are
using remote start, if equipped, to
start the vehicle from a distance,
you may not see the system check.
When the system check is
complete, either the word ON or
OFF, or the symbol for on or off, will
be visible. See Passenger Airbag
Status Indicator on page 5‑11.
The passenger sensing system
turns off the right front passenger
frontal airbag under certain
conditions. The driver airbag,
seat-mounted side impact airbags
and the roof-rail airbags are not
affected by the passenger sensing
system. The passenger sensing system
works with sensors that are part of
the right front passenger seat. The
sensors are designed to detect the
presence of a properly-seated
occupant and determine if the right
front passenger frontal airbag
should be enabled (may 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.
We recommend that children be
secured in a rear seat, including: an
infant or a child riding in a
rear-facing child restraint; a child
riding in a forward-facing child seat;
an older child riding in a booster
seat; and children, who are large
enough, using safety belts.
A label on the sun visor says,
“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 deploys.
Black plate (28,1)GMC Terrain/Terrain Denali Owner Manual - 2013 - crc 1st edition - 5/8/12
3-28 Seats and Restraints
For some children, including
children in child restraints, and for
very small adults, the passenger
sensing system may or may not turn
off the right front 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 safety 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 on page 5‑10 for more
information, including important
safety information.
If the On Indicator is Lit for 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 (Front
Passenger Seat) on page 3‑48
orSecuring Child Restraints
(Rear Seat) on page 3‑45. 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
on page 3‑2.
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 seating posture and body
build. It is better to secure the
child restraint in a rear seat.

Seats and Restraints 3-29
If the Off Indicator is Lit for an
Adult-Size Occupant
If a person of adult-size is sitting in
the right front passenger seat, but
the off indicator is lit, it could be
because that person is not sitting
properly in the seat. If this happens,
use the following steps to allow the
system to detect that person and
enable the right front passenger
frontal airbag:
1. Turn the vehicle off.2. Remove any additional material
from the seat, such as blankets,
cushions, seat covers, seat
heaters, seat massagers,
laptops, or other electronic
devices.
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. Restart the vehicle and have the person remain in this position for
two to three minutes after the on
indicator is lit.
Additional Factors Affecting
System Operation
Safety 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
“Safety 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 on
page 3‑30 for more information
about modifications that can affect
how the system operates.
A wet seat can affect the
performance of the passenger
sensing system. Here is how:
.The passenger sensing system
may turn off the passenger
airbag when liquid is soaked into
the seat. If this happens, the off
Black plate (31,1)GMC Terrain/Terrain Denali Owner Manual - 2013 - crc 1st edition - 5/8/12
Seats and Restraints 3-31
keep the airbag system from
working properly. Changing or
moving any parts of the front
seats, safety belts, the airbag
sensing and diagnostic module,
steering wheel, instrument
panel, roof-rail airbag modules,
ceiling headliner or pillar garnish
trim, overhead console, front
sensors, side impact sensors,
rollover sensor module, or airbag
wiring can affect the operation of
the airbag system.
In addition, the vehicle has a
passenger sensing system for
the right front passenger
position, which includes sensors
that are part of the passenger
seat. The passenger sensing
system may not operate properly
if the original seat trim is
replaced with non-GM covers,
upholstery or trim, or with GM
covers, upholstery or trim
designed for a different vehicle.
Any object, such as an
aftermarket seat heater or a
comfort enhancing pad ordevice, installed under or on top
of the seat fabric, could also
interfere with the operation of
the passenger sensing system.
This could either prevent proper
deployment of the passenger
airbag(s) or prevent the
passenger sensing system from
properly turning off the
passenger airbag(s). See
Passenger Sensing System on
page 3‑26.
