6. To tighten the belt, push down on
the child restraint, pull the
shoulder portion of the belt to
tighten the lap portion of the belt
and feed the shoulder belt back
into the retractor. When installing
a forward-facing child restraint, it
may be helpful to use your knee
to push down on the child
restraint as you tighten the belt.
7. Push and pull the child restraint
in different directions to be sure
it is secure.If the airbag is off, the off indicator
in the passenger airbag status
indicator will come on and stay on
when the vehicle is started.
If a child restraint has been installed
and the on indicator is lit, see
“If the On Indicator is Lit for a Child
Restraint ” underPassenger Sensing
System on page 1-54for more
information.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
Airbag System
The vehicle has the following
airbags:
A frontal airbag for the driver.
A frontal 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.
1-46 Seats and Restraint System

The vehicle may have the following
airbags:
A seat-mounted side impact
airbag for the driver.
A seat-mounted side impact
airbag for 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
headliner or 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
inating bag, all airbags must
inate very quickly to do their job.Here are the most important things
to know about the airbag system:
{CAUTION
You can be severely injured or
killed in a crash if you are not
wearing your safety belt — even if
you have airbags. Airbags are
designed to work with safety
belts, but do not replace them.
Also, airbags are not designed to
deploy in every crash. In some
crashes safety belts are your only
restraint. SeeWhen Should an
Airbag Inflate? on page 1-50.
Wearing your safety 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 safety belts. Everyone in your
vehicle should wear a safety belt
properly — whether or not there is
an airbag for that person.
Seats and Restraint System 1-47

{CAUTION
Airbags inate with great force,
faster than the blink of an eye.
Anyone who is up against, or very
close to, any airbag when it
inates can be seriously injured or
killed. Do not sit unnecessarily
close to the airbag, as you would
be if you were sitting on the edge
of your seat or leaning forward.
Safety belts help keep you in
position before and during a
crash. Always wear your 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.
{CAUTION
Children who are up against, or
very close to, any airbag when it
inates 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 your vehicle. To read
how, seeOlder Children on
page 1-25orInfants and Young
Children on page 1-28.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. SeeAirbag
Readiness Light on page 3-25for
more information.
1-48 Seats and Restraint System

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
Inate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inator. Gas from the inator lls the
airbag causing the bag to break out
of the cover and deploy. The inator,
the airbag, and related hardware are
all part of the airbag module.
Frontal airbag modules are located
inside the steering wheel and
instrument panel. For vehicles with
seat-mounted side impact airbags,
there are airbag modules in the side
of the front seatbacks closest to
the door. For vehicles with roof-rail
airbags, there are airbag modules
in the ceiling of the vehicle, near the
side windows that have occupant
seating positions.
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
rst, second, and third rows. The
rollover capable roof-rail airbags are
designed to help reduce the risk offull 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. SeeWhen Should
an Airbag Inflate? on page 1-50
for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See After
an Airbag Inates?
After the frontal airbags and
seat-mounted side impact airbags
inate, they quickly deate, so
quickly that some people may not
even realize an airbag inated.
Roof-rail airbags may still be at least
partially inated for some time after
they deploy. Some components of
the airbag module may be hot for
several minutes. For location of the
airbag modules, seeWhat Makes an
Airbag Inflate? on page 1-52.
1-52 Seats and Restraint System

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
instrument panel when the vehicle
is started.
The words ON and OFF, or the
symbol for on and off, are visible
during the system check. When the
system check is complete, the
word ON or OFF, or the symbol foron or off, will be visible. See
Passenger Airbag Status Indicator
on page 3-26.
The passenger sensing system will
turn off the right front passenger
frontal airbag and seat-mounted side
impact airbag (if equipped) under
certain conditions. The driver
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 and
safety belt. The sensors are
designed to detect the presence of a
properly-seated occupant and
determine if the right front passenger
frontal airbag and seat-mounted side
impact airbag (if equipped) should be
enabled (may inate) 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.
{CAUTION
A child in a rear-facing child
restraint can be seriously injured or
killed if the right front passenger
airbag inates. This is because
the back of the rear-facing child
restraint would be very close to
the inating airbag. A child in a
forward-facing child restraint can

1-54 Seats and Restraint System

For some children who have
outgrown child restraints and for
very small adults, the passenger
sensing system may or may not turn
off the right front passenger frontal
airbag and seat-mounted side
impact airbag (if equipped),
depending upon the person 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.
{CAUTION
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.
SeeAirbag Readiness Light on
page 3-25for 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 toSecuring a Child
Restraint in the Right Front Seat
Position on page 1-43.5. 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 1-2.
6. Restart the vehicle.
If the on indicator is still lit with a
child present in a child restraint,
secure the child restraint in a rear
seat position in the vehicle and
check with your dealer/retailer.
1-56 Seats and Restraint System

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 thesystem to detect that person and
enable the right front passenger
frontal airbag and seat-mounted side
impact airbag (if equipped):
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. 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.
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(s) off for some
adult size occupants. If this happens,
just let the belt go back all the way
and start again.
Seats and Restraint System 1-57

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 or device,
installed under or on top of theseat 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). SeePassenger
Sensing System on page 1-54.
