60 Seats and Restraints
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.
The best way to protect the fetus is
to protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety 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.
To wear it, attach it to the regularsafety belt. For more information,
see the instruction sheet that comes
with the extender.
Safety System Check
Check that the safety belt reminder,
safety belts, buckles, latch plates,
and retractors, are all working
properly. Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from performing properly. See your
dealer to have it repaired. Torn or
frayed safety belts may not protect
you in a crash. They can rip apart
under impact forces. If a belt is torn
or frayed, have it replaced
immediately.
Make sure the safety belt reminder
light is working. See
Safety Belt
Reminders 0107.
Keep safety belts clean and dry.
See Safety Belt Care 060.
Safety Belt Care
Keep belts clean and dry.
{Warning
Do not bleach or dye safety belt
webbing. It may severely weaken
the webbing. In a crash, they
might not be able to provide
adequate protection. Clean and
rinse safety belt webbing only
with mild soap and lukewarm
water. Allow the webbing to dry.
Safety belts should be properly
cared for and maintained.
Safety belt hardware should be kept
dry and free of dust or debris. As
necessary exterior hard surfaces
and safety 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.

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 0108.

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 073 or
Infants and Young Children 075.
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 0108.
Where Are the Airbags?
The driver frontal airbag is in the
center of the steering wheel.
The front outboard passenger
frontal airbag is in the passenger
side instrument panel.

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 instrument panel
when the vehicle is started.
The words ON and OFF will be
visible during the system check.
When the system check is
complete, either the word ON or
OFF will be visible. SeePassenger
Airbag Status Indicator 0108.
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.
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 age
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
(Continued)
Warning (Continued)
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.
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(Continued)

Warning (Continued)
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 that an
infant is present in a child
restraint.
. 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 0108. 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 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 0108 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.

70 Seats and Restraints
3. Remove any additional itemsfrom 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 Safety Belt in the Rear
Seat) 087 orSecuring Child
Restraints (With the Safety Belt
in the Front Seat) 089.
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 044. 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. 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. Also remove
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.

{Warning
If the front outboard passenger
airbag is turned off for an
adult-sized occupant, the airbag
will not be able to inflate and help
protect that person in a crash,
resulting in an increased risk of
serious injury or even death. An
adult-sized occupant should not
ride in the front outboard
passenger seat, if the passenger
airbag off 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 072
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
indicator will be lit, and the
airbag readiness light on the
instrument panel will also be lit.
. Liquid pooled on the seat that
has not soaked in may make it
more likely that the passenger
sensing system will turn on the passenger airbag while a child
restraint or child occupant is on
the seat. If the passenger airbag
is turned on, the on indicator will
be lit.
If the passenger seat gets wet, dry
the seat immediately. If the airbag
readiness light is lit, do not install a
child restraint or allow anyone to
occupy the seat. See Airbag
Readiness Light 0108 for important
safety information.
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.
{Warning
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.

Airbag Readiness Light 0108.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag
may not work properly. Do not
open or break the airbag
coverings. If there are any
opened or broken airbag
coverings, have the airbag
covering and/or airbag module
replaced. For the location of the
airbags, see Where Are the
Airbags? 063. See your dealer
for service.
Replacing Airbag System
Parts after a Crash
{Warning
A crash can damage the airbag
systems in the vehicle.
A damaged airbag system may
not properly protect you and your
passenger(s) in a crash, resulting
in serious injury or even death. To
help make sure the airbag
systems are working properly
after a crash, have them
inspected and any necessary
replacements made as soon as
possible.
If an airbag inflates, you will need to
replace airbag system parts. See
your dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See
Airbag Readiness Light 0108.
Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle’s safety belts.

Warning (Continued)
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 the child restraint in a
rear seat.
SeePassenger Sensing System
0 68 for additional information.
If the child restraint uses a top
tether, see Lower Anchors and
Tethers for Children (LATCH
System) 080 for top tether anchor
locations.
Do not secure a child seat in a
position without a top tether anchor
if a national or local law requires
that the top tether be anchored, or if
the instructions that come with the
child restraint say that the top strap
must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached. When using the lap-shoulder belt to
secure the child restraint in this
position, follow the instructions that
came with the child restraint and the
following instructions:
1. Move the seat as far back as it will go before securing the
forward-facing child restraint.
Move the seat upward or the
seatback to an upright position,
if needed, to get a tight
installation of the child
restraint.
When the passenger sensing
system has turned off the front
outboard passenger frontal
airbag, the off indicator on the
passenger airbag status
indicator should light and stay
lit when you start the vehicle.
See Passenger Airbag Status
Indicator 0108.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder portions
of the vehicle's safety belt through or around the restraint.
The child restraint instructions
will show you how.
4. Push the latch plate into the
buckle until it clicks.
Position the release button on
the buckle, away from the child
restraint system, so that the
safety belt could be quickly
unbuckled if necessary.
