On some models, Buckle to Drive may
also prevent shifting out of P (Park) if
a front passenger is unbuckled under
similar conditions. A message displays
in the DIC. Buckle the front passenger
seat belt to shift out of P (Park). This
feature may not allow the vehicle to
shift out of P (Park) if an object, such
as a briefcase, handbag, grocery bag,
laptop, or other electronic device, is
on the front passenger seat. If this
happens, remove the object from the
seat or buckle the seat belt to shift
out of P (Park).
If the driver, or on some vehicles, the
present front passenger remains
unbuckled, the DIC message will turn
off after several seconds and the
vehicle can be shifted out of P (Park).
See“Seat Belts” and“Child Restraints”
in the Index for information about the
importance of proper restraint use.
If the driver seat belt or the front
passenger seat belt is unbuckled when
driving, the seat belt reminder chime
and light(s) will come on. See Seat Belt
Reminders 097. This feature may not function properly if the airbag
readiness light is on. See
Airbag
Readiness Light 098.
How to Wear Seat Belts
Properly
Follow these rules for everyone's
protection.
There are additional things to know
about seat belts and children,
including smaller children and infants.
If a child will be riding in the vehicle,
see Older Children 060 or
Infants and Young Children 061.
Review and follow the rules for
children in addition to the following
rules.
It is very important for all occupants
to buckle up. Statistics show that
unbelted people are hurt more often
in crashes than those who are wearing
seat belts.
There are important things to know
about wearing a seat belt properly.
.Sit up straight and always keep your
feet on the floor in front of you (if
possible).
.Wear the lap part of the belt low
and snug on the hips, just touching
the thighs. In a crash, this applies
force to the strong pelvic bones and
you would be less likely to slide
under the lap belt. If you slid under
it, the belt would apply force on
your abdomen. This could cause
serious or even fatal injuries.

3. Pick up the latch plate and pull thebelt 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 is pulled out all the
way, the child restraint locking
feature may be engaged. See Child
Restraint Systems 063. If this
occurs, let the belt go back all the
way and start again. If the locking
feature stays engaged after letting
the belt go back to stowed position
on the seat, move the seat rearward
or recline the seat until the
shoulder belt retractor lock
releases.
Engaging the child restraint locking
feature in the front outboard
seating position may affect the
passenger sensing system. See
Passenger Sensing System 054. If the shoulder portion of the driver
belt is pulled out all the way, the
shoulder belt retractor lock feature
may be engaged. If this happens,
let the belt go back all the way and
start again. If the locking feature
stays engaged after letting the belt
go back to stowed position on the
seat, move the seat rearward or
recline the seat until the shoulder
belt retractor lock releases.
If the webbing locks in the latch
plate before it reaches the buckle,
tilt the latch plate flat to unlock.
4. 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, see Seat Belt Extender
0 47.
Position the release button on the
buckle so that the seat belt could
be quickly unbuckled if necessary.

seat belts can rip apart under impact
forces. If a belt is torn or frayed, have
it replaced immediately. If a belt is
twisted, it may be possible to untwist
by reversing the latch plate on the
webbing. If the twist cannot be
corrected, ask your dealer to fix it.
Make sure the seat belt reminder light
is working. SeeSeat Belt Reminders
0 97.
Keep seat belts clean and dry. See Seat
Belt Care 048.
Seat Belt Care
Keep belts clean and dry.
Seat belts should be properly cared for
and maintained.
Seat belt hardware should be kept dry
and free of dust or debris. As
necessary, exterior hard surfaces and
seat 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.
{Warning
Do not bleach or dye seat belt
webbing. It may severely weaken
the webbing. In a crash, they might
not be able to provide adequate
protection. Clean and rinse seat belt
webbing only with mild soap and
lukewarm water. Allow the webbing
to dry.
Replacing Seat Belt
System Parts after a Crash
{Warning
A crash can damage the seat belt
system in the vehicle. A damaged
seat 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 seat 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
seat belts may not be necessary. But
the seat belt assemblies that were
used during any crash may have been
stressed or damaged. See your dealer
to have the seat belt assemblies
inspected or replaced.
New parts and repairs may be
necessary even if the seat belt system
was not being used at the time of the
crash.
Have the seat 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 098.
Airbag System
The vehicle has the following airbags:
.A frontal airbag for the driver
.A frontal airbag for the front
outboard passenger
.A knee airbag for the driver.

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 060 or
Infants and Young Children 061.
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 098.
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.
The driver knee airbag is below the
steering column. The front outboard
passenger knee airbag is below the
glove box.

locked, the interior lamps can be
turned off, and the hazard warning
flashers can be turned off using the
controls for those features. If any of
these systems are damaged in the
crash they may not operate as normal.
{Warning
A crash severe enough to inflate the
airbags may have also damaged
important functions in the vehicle,
such as the fuel system, brake and
steering systems, etc. Even if the
vehicle appears to be drivable after
a moderate crash, there may be
concealed damage that could make
it difficult to safely operate the
vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.Airbags are designed to inflate only
once. After an airbag inflates, 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. See
Vehicle Data Recording and Privacy
0 439 and
Event Data Recorders 0440.
.Let only qualified technicians work
on the airbag system. Improper
service can mean that an airbag
system will not work properly. See
your dealer for service.
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 overhead console when the vehicle
is started.
The words ON and OFF, and the
symbols for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or OFF, and the symbol for
on or off, will be visible. See Passenger
Airbag Status Indicator 098.
The passenger sensing system turns
off the front outboard passenger
frontal airbag and knee 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 and seat belt.
The sensors are designed to detect the
presence of a properly seated
occupant and determine if the front
outboard passenger frontal airbag and
knee airbag should be allowed to
inflate or not.

SEATS AND RESTRAINTS 55
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 aged
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 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.(Continued)
Warning (Continued)
Even if the passenger sensing
system has turned off the front
outboard passenger airbag(s), no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag(s) are 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 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 and
knee airbag if:
.The front outboard passenger seat
is unoccupied.
.The system determines 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.
When the passenger sensing system
has turned off the front outboard
passenger frontal airbag and knee
airbag, the OFF indicator will light and
stay lit as a reminder that the airbags
are off. See Passenger Airbag Status
Indicator 098.
The passenger sensing system is
designed to turn on the front
outboard passenger frontal airbag and
knee 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 airbags to be enabled,
the ON indicator will light and stay lit
as a reminder that the airbags are
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 and
knee airbag, depending upon the
person's seating posture and body
build. Everyone in the vehicle who has
outgrown child restraints should wear
a seat 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 098 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 and
knee 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.
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 (With the Seat Belt in the
Rear Seat) 073 or
Securing Child Restraints (With the
Seat Belt in the Front Seat) 075.
Make sure the seat belt retractor is
locked by pulling the shoulder belt
all the way out of the retractor
when installing the child restraint,
even if the child restraint is
equipped with a seat belt lock off.
When the retractor lock is set, the
belt can be tightened but not
pulled out of the retractor. 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 030.
6. Restart the vehicle.
The passenger sensing system may or
may not turn off the airbags 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.

sensing and diagnostic module, and
airbag wiring along with the proper
replacement procedures.
In addition, the vehicle has a
passenger sensing system for the front
outboard 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
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). SeePassenger Sensing
System 054.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0380 for additional important
information. If the vehicle must be modified
because you have a disability and have
questions about whether the
modifications will affect the vehicle's
airbag system, or if you have
questions about whether the airbag
system will be affected if the vehicle is
modified for any other reason, call
Customer Assistance. See
Customer
Assistance Offices 0430.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See Airbag
Readiness Light 098.
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? 050. See
your dealer for service.
