belt functions are not affected by the
Automatic Seat Belt Tightening
System.
Seat Belt Pretensioners
This vehicle has seat belt
pretensioners for front outboard
occupants. Although the seat belt
pretensioners cannot be seen, they are
part of the seat belt assembly. They
can help tighten the seat 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. Seat
belt pretensioners can also help
tighten the seat belts in a side crash
or a rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash, the
pretensioners and probably other
parts of the vehicle's seat belt system
will need to be replaced. See
Replacing
Seat Belt System Parts after a Crash
0 83.
Do not sit on the outboard seat belt
while entering or exiting the vehicle or
at any time while sitting in the seat.
Sitting on the seat belt can damage
the webbing and hardware.
Rear Seat Belt Comfort Guides
Rear seat belt comfort guides may

{Warning
When an airbag inflates, 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 inflates, 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
on the interior lamps and hazard
warning flashers, and shut off the fuel
system after the airbags inflate. The
feature may also activate, without
airbag inflation, after an event that
exceeds a predetermined threshold.
After turning the ignition off and then
on again, the fuel system will return to normal operation; the doors can be
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 0412 and
Event Data Recorders 0412.
. Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.

SEATS AND RESTRAINTS 91
Warning (Continued)
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 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 and knee
airbag, the OFF indicator will light and
stay lit as a reminder that the airbags
are off. See Passenger Airbag Status
Indicator 0138.
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
airbag(s) to be enabled, the ON
indicator will light and stay lit as a
reminder that the airbag(s) 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 0138 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.

Servicing the
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 and the
service manual have information
about servicing the vehicle and the
airbag system. To purchase a service
manual, seePublication Ordering
Information 0410.
{Warning
For up to 10 seconds after the
vehicle is turned off and the 12‐volt
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. 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 qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet metal
may keep the airbag system from
working properly.
The operation of the airbag system
can also be affected by changing,
including improperly repairing or
replacing, any parts of the following:
.
Airbag system, including airbag
modules, front or side impact
sensors, sensing and diagnostic
module, or airbag wiring
. Front seats, including stitching,
seams or zippers
. Seat belts
. Steering wheel, instrument panel,
overhead console, ceiling trim,
or pillar garnish trim
. Inner door seals, including
speakers
Your dealer and the service manual
have information about the location of
the airbag modules and sensors, 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). See
Passenger Sensing
System 090.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0356 for additional important
information.
