When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal
or near-frontal crashes. But they are designed to inate
only if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account
a variety of desired deployment and non-deployment
events and are used to predict how severe a crash
is likely to be in time for the airbags to inate and help
restrain the occupants. Whether your frontal airbags
will or should deploy is not based on how fast your
vehicle is traveling. It depends largely on what you hit,
the direction of the impact and how quickly your
vehicle slows down.
In addition, your vehicle has “dual-stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle has an electronic frontal sensor which helps
the sensing system distinguish between a moderate
frontal impact and a more severe frontal impact.
For moderate frontal impacts, these airbags inate at a
level less than full deployment. For more severe frontal
impacts, full deployment occurs. If the front of your
vehicle goes straight into a wall that does not move or
deform, the threshold level for the reduced deployment
is about 12 to 16 mph (19 to 26 km/h), and the
threshold level for a full deployment is about
18 to 24 mph (29 to 38.5 km/h).The threshold level can vary, however, with specic
vehicle design, so that it can be somewhat above or
below this range.
Frontal airbags may inate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbags
could inate at a different crash speed than if the
vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash speed than
if the vehicle hits an object that does not deform.
If the vehicle hits a narrow object (like a pole) the
airbags could inate at a different crash speed
than if the vehicle hits a wide object (like a wall).
If the vehicle goes into an object at an angle the
airbags could inate at a different crash speed
than if the vehicle goes straight into the object.
Frontal airbags (driver and right front passenger) are
not intended to inate during vehicle rollovers, rear
impacts, or in many side impacts.
Your vehicle may or may not have roof-mounted side
impact airbags. SeeAirbag System on page 1-53.
Roof-mounted side impact airbags are intended to inate
in moderate to severe side crashes. A roof-mounted side
impact airbag will inate if the crash severity is above the
system’s designed threshold level.

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
passenger’s frontal airbag 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.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Your vehicle has a rear seat that will accommodate a
rear-facing child restraint. 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
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 passenger’s frontal
airbag 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 the
rear seat, even if the airbag is off.
If you need to 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.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, front end or side sheet
metal or height, they may keep the airbag system
from working properly. Also, the airbag system may
not work properly if you relocate any of the airbag
sensors. If you have any questions about this,
you should contact Customer Assistance before
you modify your vehicle. The phone numbers
and addresses for Customer Assistance are in
Step Two of the Customer Satisfaction Procedure
in this manual. SeeCustomer Satisfaction
Procedure on page 7-2
Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module (located under the center console), or the
instrument panel can affect the operation of the
airbag system. If you have questions, call Customer
Assistance. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure on page 7-2.

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers are turned on. For this feature
to work, automatic lighting must be enabled. See
Headlamps on page 3-13for additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also turn
off 15 seconds after the windshield wiper control is
turned off.
Headlamps on Reminder
If you open the driver’s door with the ignition off and the
lamps on, you will hear a warning chime.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles rst sold in
Canada. The vehicle has a light sensor on top of the
instrument panel. Make sure it is not covered, or the
head lamps will be on when not needed.
The DRL system will make your front turn signal lamps
come on when the following conditions are met:
The ignition is on.
The exterior lamps control is in AUTO or the
parking lamps only position.
The light sensor detects daytime light.
The parking brake is released.
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps, and instrument panel lights
will not be illuminated unless you have turned the
exterior lamps control to the parking lamp position.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Passenger Safety Belt
Reminder Light
If equipped, several seconds after the key is turned to
RUN or START, a chime will sound for several seconds
to remind the front passenger to buckle their safety
belt. This would only occur if the passenger airbag is
enabled. SeePassenger Sensing System on page 1-62
for more information. The passenger safety belt light
will also come on and stay on for several seconds, then
it will ash for several more.
This chime and light will be
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither the
chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, 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 check includes the airbag sensor, the airbag
modules, the wiring and the crash sensing and diagnostic
module. For more information on the airbag system, see
Airbag System on page 1-53.
This light will come on
when you start your
vehicle, and it will ash for
a few seconds. Then the
light should go out. This
means the system is ready.
