Frontal airbags for the driver and right front passenger
may also deploy if a serious impact occurs to the
underside of your vehicle such as hitting a curb, falling
into a deep hole, or landing hard.
In addition, your vehicle has dual-stage frontal airbags.
Dual-stage airbags adjust the restraint according to
crash severity. Your vehicle has electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more severe
frontal impact. For moderate frontal impacts, dual-stage
airbags inate at a level less than full deployment.
For more severe frontal impacts, full deployment occurs.
Your vehicle may or may not have seat-mounted side
impact and roof-rail airbags. SeeAirbag System on
page 1-50. Seat-mounted side impact and roof-rail
airbags are intended to inate in moderate to severe side
crashes. Seat-mounted side impact and roof-rail airbags
will inate if the crash severity is above the system’s
designed threshold level. Your vehicle has sensors
which detect side impacts. These sensors signal the
appropriate side impact airbag to inate. The threshold
level can vary with specic vehicle design.Seat-mounted side impact and roof-rail airbags are not
intended to inate in frontal impacts, near-frontal impacts,
rollovers, or rear impacts. A seat-mounted side impact
airbag is intended to deploy on the side of the vehicle that
is struck. A roof-rail airbag is intended to deploy on the
side of the vehicle that is struck. It is possible that, in a
crash involving the rear side of your vehicle, that only the
roof-mounted airbag will deploy.
In any particular crash, no one can say whether an airbag
should have inated simply because of the damage to a
vehicle or because of what the repair costs were. For
frontal airbags, ination is determined by what the vehicle
hits, the angle of the impact, and how quickly the vehicle
slows down. For seat-mounted side impact and roof-rail
airbags, deployment is determined by the location and
severity of the side impact.

The passenger sensing system will also turn off the
right front passenger’s safety belt pretensioner if
it detects that there is no occupant in that position.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety belt.
The sensors are designed to detect the presence of a
properly-seated occupant and determine if the right front
passenger’s frontal airbag and seat-mounted side impact
airbag (if equipped) should be enabled (may inate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing
child restraint; a child riding in a forward-facing child
seat; an older child riding in a booster seat; and children,
who are large enough, using safety belts.
A label on your sun visor says, “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 deploys.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
CAUTION: (Continued)
CAUTION: (Continued)
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the passenger sensing system is
designed to turn off the right front passenger’s
frontal and seat-mounted side impact airbag
(if equipped) if the system detects a rear-facing
child restraint, no system is fail-safe, and
no one can guarantee that an airbag will not
deploy under some unusual circumstance,
even though it is turned off. We recommend
that rear-facing child restraints be secured
in a rear seat, even if the airbag(s) are off.
If you secure a forward-facing child restraint
in the right front seat, always move the front
passenger seat as far back as it will go. It is
better to secure the child restraint in a rear seat.
The passenger sensing system is designed to turn
off the right front passenger’s frontal airbag and
seat-mounted side impact airbag (if equipped) if:
The right front passenger seat is unoccupied.
The system determines that an infant is present
in a rear-facing infant seat.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, front sensors, or airbag wiring
can affect the operation of the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger’s position, which
includes sensors that are part of the passenger’s
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 on page 1-59.

Automatic Headlamp System
Your vehicle has an automatic light sensor on the top
left corner of the instrument panel, so be sure it is
not covered or the headlamps will be on continuously.
When it is dark enough outside, the automatic headlamp
system will turn on the low-beam headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and instrument
panel lights. This is indicated by the headlamp symbol
on your instrument panel cluster. SeeInstrument
Panel Cluster on page 3-26.
If you are driving through a parking garage, overcast
weather, or a tunnel, the automatic headlamp system
may turn on the low-beam headlamps at a normal
brightness along with the taillamps, sidemarker, parking
lamps and the instrument panel lights. The radio lights
will be dimmer, and the instrument panel cluster lights
may dim. There will be a delay before the lights will turn
on when starting the car at night.
Fog Lamps
-(Fog Lamps):Turn the band on the turn
signal/multifunction lever to the fog lamp symbol
to turn the fog lamps on. They will come on only
when the headlamps are on low beam.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Instrument Panel Brightness
The instrument panel
brightness control is
located to the left of
the steering wheel on
the instrument panel.
Turn the wheel on the
left of the control up or
down to increase or
decrease brightness.
Turn the wheel all the way up for the maximum setting.
It is recommended that the brightness level be kept
at the maximum setting for all daytime driving to
ensure proper visibility.
The brightness of the instrument panel lights will
decrease when the headlamps are on.

supply: microcomputer-controlled electric blankets,
touch sensor lamps, etc.
Ashtray(s) and Cigarette Lighter
Notice:If you put papers, pins, or other ammable
items in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
your vehicle. Never put ammable items in the
ashtray.
To use the lighter, if your vehicle has one, push the
lighter in all the way and let go. When it is ready, it will
pop back out by itself. If the engine is not running,
the key must be in ACC to use the lighter.
It is not recommended to use the cigarette lighter to
plug in auxiliary electrical equipment. Use the accessory
power outlet for phones and other electrical equipment.
SeeAccessory Power Outlet(s) on page 3-18or
Power Outlet 115 Volt Alternating Current on page 3-18.
Notice:Holding a cigarette lighter in while it is
heating does not let the lighter back away from
the heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold
a cigarette lighter in while it is heating.
Your vehicle may have a removable ashtray that sits in
your front cupholder in the center console storage area.

When the key is turned to ON or START, this light will
come on as a reminder for the right front passenger to
fasten their safety belt. This light will ash until the right
front passenger’s safety belt is buckled. The passenger’s
safety belt reminder light will not come on if the right front
passenger’s belt is already buckled or if a sensor does
not detect the weight of a passenger in that seat.
If something is placed on the right front passenger
seat, the sensors in the seat may detect that object and
cause the right front passenger safety belt reminder
light to come on. If this happens, remove the object.
Airbag Readiness Light
There is an airbag readiness light on the instrument panel
cluster, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The light tells you if there is an electrical problem. The
system monitors the airbag sensor assembly, front airbag
sensors, seat-mounted side impact and roof-mounted
airbag sensors, driver’s seat position sensor, driver’s seat
belt buckle switch, right front occupant sensing system
and indicator light, front passenger’s seat belt buckle
switch, seat belt pretensioner assemblies, inators,
interconnecting wiring and power sources. For more
information on the airbag system, seeAirbag System
on page 1-50.This light will come on
briey when you start
your vehicle, then it
should go out and the
system is ready.
If the airbag readiness light stays on after you start
the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on or keeps
ashing after you start your vehicle, it means
the airbag system and safety belt pretension
system may not be working properly. The
airbags in your vehicle may not inate in a
crash, or they could even inate without a
crash. To help avoid injury to yourself or others,
have your vehicle serviced right away if the
airbag readiness light stays on after you start
your vehicle.

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure readings
to a receiver located in the vehicle.
Each tire, including the spare (if provided), should be
checked monthly when cold and inated to the ination
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire ination pressure label.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire ination
pressure label, you should determine the proper
tire ination pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one
or more of your tires is signicantly under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inate them to the proper
pressure. Driving on a signicantly under-inated tire
causes the tire to overheat and can lead to tire failure.
Under-ination also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling
and stopping ability.Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-ination
has not reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indicator
is combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will
ash for approximately one minute and then remain
continuously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as the
malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur
for a variety of reasons, including the installation
of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle
to ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to function
properly.
SeeTire Pressure Monitor Operation on page 5-58,
for additional information.
