Lap-Shoulder Belt
All seating positions in the vehicle have a lap-shoulder
belt except for the center front passenger position, if
equipped, which has a lap belt. SeeLap Belt on
page 1-52for more information.
The lap-shoulder belts for the rst and second row
seating positions are equipped with free-falling latch
plates. If the vehicle has a third row, the lap-shoulder
belts have either free-falling or cinching latch plates.
Use the following pictures to determine the latch
plate style:
The following instructions explain how to wear a
lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you can
sit up straight. To see how, see “Seats” in the Index.
2. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The lap-shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.

If the shoulder portion of a passenger belt with a
free-falling latch plate is pulled out all the way, the
child restraint locking feature may be engaged.
If this happens, let the belt go back all the way and
start again.
Engaging the child restraint locking feature in the
right front seating position may affect the passenger
sensing system. SeePassenger Sensing System
on page 1-90for more information.
If the belt stops before it reaches the buckle, for
lap-shoulder belts with cinching latch plates, tilt the
latch plate and keep pulling the safety belt until
it can be buckled.3. Push the latch plate into the buckle until it clicks. If
you nd that the latch plate will not go fully into the
buckle, see if you are using the correct buckle.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-53.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for the
driver and right front passenger positions.
Adjust the height so that the shoulder portion of the belt
is centered on the shoulder. The belt should be away
from the face and neck, but not falling off the shoulder.
Improper shoulder belt height adjustment could
reduce the effectiveness of the safety belt in a crash.
Squeeze the buttons (A)
on the sides of the height
adjuster and move the
height adjuster to the
desired position.
The adjuster can be moved up just by pushing up on
the shoulder belt guide.
After the adjuster is set to the desired position, try to
move it down without squeezing the buttons to
make sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt pretensioners for front
outboard occupants. Although the safety belt
pretensioners cannot be seen, they are part of the safety
belt assembly. They can help tighten the safety 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. And, if the vehicle has
side impact airbags, safety belt pretensioners can help
tighten the safety belts in a side crash or a rollover event.
Pretensioners work only once. If the pretensioners
activate in a crash, they will need to be replaced, and
probably other new parts for the vehicle’s safety
belt system. SeeReplacing Restraint System Parts
After a Crash on page 1-99.
Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide added
safety 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 belt away
from the neck and head.

{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 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.
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 safety belts.
Refer to your child restraint manufacturer
instructions and the instructions in this manual.
1.1. Find the lower anchors for the desired
seating position.
1.2. Put the child restraint on the seat.
1.3. Attach and tighten the lower attachments on
the child restraint to the lower anchors.

4. For passenger seating positions with a lap-shoulder
belt and a free-falling latch plate, pull the rest of the
shoulder belt all the way out of the retractor to
set the lock. When installing a child restraint using
a lap-shoulder belt and a cinching latch plate,
skip Step 4 and proceed to Step 5.5. 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.

5. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.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.
1-80

If your vehicle has roof-rail airbags and a third row
passenger seat, the airbags are located in the ceiling
above the rear windows for the outboard passenger
positions in the third row.
{CAUTION:
If something is between an occupant and an
airbag, the airbag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating 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.
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 inating roof-rail airbag will be
blocked. Driver Side shown, Passenger Side similar
1-85

{CAUTION:
When an airbag inates, 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 inates, 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 the interior lamps on, and turn the
hazard warning ashers on when the airbags inate.
You can lock the doors, turn the interior lamps off, and
turn the hazard warning ashers off by using the
controls for those features.In many crashes severe enough to inate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur
from the right front passenger airbag.Airbags are designed to inate only once. After an
airbag inates, 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.
SeeVehicle Data Recording and Privacy on
page 7-16andEvent Data Recorders on page 7-17.
Let only qualied technicians work on the airbag
systems. Improper service can mean that an
airbag system will not work properly. See your
dealer/retailer for service.

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 off for some adult size
occupants. If this happens, let the belt go back all the
way and start again.
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 1-96for more
information about modications 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.
{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.
