Warning (Continued)
or it might force the object into
that person causing severe injury
or even death. The path of an
inflating 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.
Do not use seat accessories that
block the inflation path of a
seat-mounted side impact airbag.
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
inflating roof-rail airbag will be
blocked.
When Should an Airbag
Inflate?
This vehicle is equipped with
airbags. SeeAirbag System 049.
Airbags are designed to inflate
when the ignition is in the ON
position and the impact exceeds the
specific airbag system's deployment
threshold. Deployment thresholds
are used to predict how severe a
crash is likely to be in time for the
airbags to inflate and help restrain
the occupants. The vehicle has
electronic sensors that help the
airbag system determine the
severity of the impact. Deployment
thresholds can vary with specific
vehicle design.
Frontal airbags are designed to
inflate in higher severity frontal
collisions, although they may inflate
if the forces in another type of
collision are similar to those of a
higher severity frontal impact, to
help reduce the potential for severe
injuries, mainly to the driver's or
front outboard passenger's head
and chest. Frontal airbags do not
provide restraint to the lower body. Depending upon sensor input and
crash severity, it is possible that
only one frontal airbag may inflate
during a crash.
In addition, the vehicle has
advanced technology frontal
airbags. Advanced technology
frontal airbags adjust the restraint
according to crash severity and seat
belt usage.
In any particular crash, no one can
say whether an airbag should have
inflated simply because of the
vehicle damage or repair costs.
{Warning
.
The front airbags ordinarily
will not inflate in the event of
a side impact, rear impact,
rollover, or lower severity
frontal collision. Always
wear your seat belt to help
reduce the risk or severity of
injury in various kinds of
accidents.

Seats and Restraints 53
Warning (Continued)
.The front passenger airbag
will not inflate if the
passenger airbag status
indicator is lit or if the front
passenger seat is
unoccupied. For more
information, see Passenger
Airbag Status Indicator 090.
. The seat belts and the front
airbags are most effective
when you are sitting well
back and upright in the seat
with both feet on the floor.
The front airbags inflate with
great force. Even with the
advanced airbag system,
if you are unrestrained,
leaning forward, sitting
sideways, or out of position
in any way, you are at
greater risk of injury or
death in a crash. You may
also receive serious or fatal
injuries from the front airbag
if you are up against it when
(Continued)
Warning (Continued)
it inflates. Always sit back
against the seatback and as
far away as practical from
the steering wheel or
instrument panel. Always
properly use the seat belts.
. The driver and front
passenger seat belt buckles
are equipped with sensors
that detect if the seat belts
are fastened. The advanced
airbag system monitors the
severity of a collision and
seat belt usage, then
inflates the airbags as
needed. Failure to properly
wear the seat belts can
increase the risk or severity
of injury in an accident.
. The front passenger seat is
equipped with a Passenger
Sensing System (weight
sensor) that turns the front
passenger airbag off under
some conditions. This
(Continued)
Warning (Continued)
sensor is only used in this
seat. Failure to be properly
seated and wearing the seat
belt can increase the risk or
severity of injury in an
accident. For more
information, seePassenger
Airbag Status Indicator 090.
. Keep hands on the outside
of the steering wheel.
Placing them inside the
steering wheel rim could
increase the risk that they
are injured when the front
airbag inflates.

Seats and Restraints 57
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.
If the front outboard passenger seat
is unoccupied, the passenger airbag
status indicator will remain lit, and
the front outboard passenger frontal
airbag will be turned off.
{Warning
To ensure proper operation of the
passenger’s advanced airbag
system, observe the following
items:
. Do not place heavy loads
heavier than 1 kg (2.2 lb) on
the seatback, in the
underseat storage bin, head
restraint, or in the seatback
pocket.
(Continued)
Warning (Continued)
.Do not store luggage behind
the seat that can press into
the seatback.
. If a forward-facing child
restraint is installed in the
passenger seat, do not
position the passenger seat
so the child restraint
contacts the instrument
panel. If the child restraint
does contact the instrument
panel, the system may
determine the seat is
occupied and the passenger
airbag may deploy in a
collision. Also, the
passenger airbag status
indicator may not light. For
more information, see
Securing Child Restraints
075 for information about
installing and using child
restraints.
(Continued)
Warning (Continued)
.Confirm the operating
condition with the
passenger airbag status
indicator.
. If you notice that the
passenger airbag status
indicator light is not
operating as described in
this section, take your
vehicle to your dealer to
check the passenger
sensing system.
According to accident statistics,
children are safer when properly
secured in a rear seat in a correct
child restraint for their weight
and size.
Rear-facing child restraints should
not be transported in the vehicle,
even if the airbag is off.
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.

vehicle is turned off and the
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
any parts of the front seats, seat
belts, airbag sensing and diagnostic
module, steering wheel, instrument
panel, inner door seals including the
speakers, any of the airbag
modules, ceiling or pillar garnish
trim, front sensors, side impact
sensors, or airbag wiring.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
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 notoperate 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
0 56.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires
and Wheels 0216 for additional
important information.

Instruments and Controls 89
Here are four things that some
owners ask about. None of these
show a problem with the fuel gauge:
.At the service station, the gas
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
. The indicator moves a little when
turning a corner or speeding up.
. The gauge goes back to empty
when the ignition is turned off.
Seat Belt Reminders
The light and chime remind you to
fasten your seat belts. The light
illuminates when the ignition is
placed in ON or START and remains
illuminated until the driver ’s seat belt
is fastened. At the same time, the
chime sounds for about six seconds
unless the driver ’s seat belt is
securely fastened.
The seat belt warning light may also
illuminate if the front passenger ’s
seat belt is not fastened when the
front passenger seat is occupied.
For seven seconds after the ignition
switch is placed in ON, the system
does not activate the warning light
for the front passenger.
{Warning
If the seat belt warning light stays
on continuously while the ignition
is turned ON with all doors closed
and all seat belts fastened, it may
indicate a malfunction in the
system. Have the system
checked by your dealer.
See Seat Belts 043.

Control
System Operation
The vehicle has a Traction Control
System (TCS) and Electronic
Stability Control, an electronic
stability control system. These
systems use various sensors to
monitor driver inputs and vehicle
motion. Under certain driving
conditions, the TCS and Electronic
Stability Control systems help to
perform the following functions:
. Control brake pressure to reduce
wheel slip on one slipping drive
wheel so power is transferred to
a non–slipping drive wheel on
the same axle.
. Control brake pressure and
engine output to reduce drive
wheel slip based on vehicle
speed (traction control function).
