3. Push the latch plate into the
buckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, seeSafety
Belt Extender on page 1-25.
Position the release button on
the buckle so that the safety 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
Adjustment” later in this section
for instructions on use and
important safety information.
5. To make the lap part tight, pull
up on the shoulder belt.
It may be necessary to pull
stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.To unlatch the belt, push the button
on the buckle. The belt should return
to its stowed position. Slide the latch
plate up the safety belt webbing
when the safety belt is not in use.
The latch plate should rest on the
stitching on the safety belt, near the
guide loop on the side wall.
Before a door is closed, be sure the
safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
safety belt and the vehicle.
Seats and Restraint System 1-21

{CAUTION
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. To reduce the risk of
serious or fatal injuries during a
crash, attach only one child
restraint per anchor.
{CAUTION
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck and
the safety belt continues to
tighten. Buckle any unused safety

CAUTION (Continued)
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, if
your vehicle has one, after the
child restraint has been installed.
Notice:Do not let the LATCH
attachments rub against the
vehicle’s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to avoid
rubbing the LATCH attachments.
Do not fold the empty rear seat
with a safety belt buckled. This
could damage the safety belt or
the seat. Unbuckle and return the
safety belt to its stowed position,
before folding the seat.
H3T Models
1. If the child restraint manufacturer
recommends that the top tether
be attached, attach and tightenthe top tether to the top tether
anchor (A), if equipped. Refer to
the child restraint instructions and
the following steps:
1.1. Put the child restraint on
the seat.
1.2. Pull the seatback forward
to access the top tether
anchors (A). See60/40 Split
Bench Seat (H3) on page 1-7
or60/40 Split Bench
Seat (H3T) on page 1-9
for additional information.
Seats and Restraint System 1-37

7. If the child restraint has a top
tether, follow the child restraint
manufacturer’s instructions
regarding the use of the top
tether. SeeLower Anchors and
Tethers for Children (LATCH) on
page 1-34for more information.
For H3T models, if the headrest
interferes with the installation of
the child restraint, remove the
headrest by pressing the button
on the headrest post, at the top of
the seatback and lift to remove.
Store the headrest under the
outboard side of the rear seat.
8. Push and pull the child restraint
in different directions to be sure
it is secure.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it. If the
headrest has been removed, reinsert
in onto the seatback.Securing a Child
Restraint in the Center
Rear Seat Position
Many child restraints are too wide to
be correctly secured in the center
rear seat, although some of
them will t there. If the center seat
position is too narrow for the
child restraint, secure it in a rear
outside seat position.
If a child restraint is secured in the
center seat position, follow the
instructions inSecuring a Child
Restraint in a Rear Outside Seat
Position on page 1-41.
Securing a Child
Restraint in the Right
Front Seat Position
The vehicle has airbags. A rear
seat is a safer place to secure
a forward-facing child restraint.
SeeWhere to Put the Restraint
on page 1-32.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the right
front passenger frontal airbag under
certain conditions. SeePassenger
Sensing System on page 1-54
andPassenger Airbag Status
Indicator on page 3-26for more
information, including important
safety information.
Seats and Restraint System 1-43

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

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

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 specic
vehicle. SeeAdding Equipment
to Your Airbag-Equipped Vehicle on
page 1-58for more information
about modications that can affect
how the system operates.
{CAUTION
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing Your
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer/retailer and the service
manual have information about
servicing the vehicle and the airbag
system. To purchase a service
manual, seeService Publications
Ordering Information on page 7-15.
{CAUTION
For up to 10 seconds after the
ignition is turned off and the battery
is disconnected, an airbag can still
inate during improper service.
You can be injured if you are close
to an airbag when it inates.
(Continued)
CAUTION (Continued)
Avoid yellow connectors. They are
probably part of the airbag
system. Be sure to follow proper
service procedures, and make
sure the person performing work
for you is qualied to do so.
Adding Equipment to
Your Airbag-Equipped
Vehicle
Q:Is there anything I might add to
or change about the vehicle
that could keep the airbags
from working properly?
A:Yes. If you add things that
change the vehicle’s frame,
bumper system, height, front end
or side sheet metal, they may
keep the airbag system from
working properly. Changing or
moving any parts of the front
