Frontal airbags may inflate at different crash speeds.
For example:•
If the vehicle hits a stationary object, the airbags
could inflate at a different crash speed than if the
vehicle hits a moving object.
•
If the vehicle hits an object that deforms, the
airbags could inflate 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 inflate 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 inflate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with specific vehicle design.
Frontal airbags are not intended to inflate during vehicle
rollovers, rear impacts, or in many side impacts.
In addition, the vehicle has dual-stage frontal airbags.
Dual-stage airbags adjust the restraint according to
crash severity. The 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 inflate at a level less than full deployment.
For more severe frontal impacts, full deployment occurs.The vehicle has seat-mounted side impact and
roof-rail airbags. SeeAirbag System on page 2-56.
Seat-mounted side impact and roof-rail airbags
are intended to inflate in moderate to severe side
crashes. Seat-mounted side impact and roof-rail airbags
will inflate if the crash severity is above the system’s
designed threshold level. The threshold level can
vary with specific vehicle design.
Roof-rail airbags are not intended to inflate in rollovers
or rear impacts. A seat-mounted side impact airbag
is intended to deploy on the side of the vehicle that is
struck. Both roof-rail airbags will deploy when either side
of the vehicle is struck.
In any particular crash, no one can say whether an
airbag should have inflated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, inflation 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.

Passenger Sensing SystemThe vehicle has a passenger sensing system for the
right front passenger position. The passenger airbag
status indicator will be visible on the instrument
panel when the vehicle is started.
The words ON and OFF, or the symbol for on and off,
will be visible during the system check. If you are
using remote start to start the vehicle from a distance, if
equipped, you may not see the system check. When
the system check is complete, either the word ON or the
word OFF, or the symbol for on or off, will be visible.
SeePassenger Airbag Status Indicator on page 4-25.The passenger sensing system will turn off the right
front passenger frontal airbag under certain conditions.
The driver airbag, seat-mounted side impact airbags,
and roof-rail airbags are not affected by the passenger
sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger seat. The sensors
are designed to detect the presence of a properly-seated
occupant and determine if the right front passenger
frontal airbag should be enabled (may inflate) or not.
According to accident statistics, children are safer when
properly secured in a rear seat in the correct child
restraint for their weight and size.
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 the 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. United States

Adding Equipment to Your
Airbag-Equipped VehicleQ:
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 the 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, side impact
sensors, or airbag wiring can affect the operation of
the airbag system.
In addition, the vehicle has a passenger sensing
system for the right front passenger 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 2-66.

Daytime Running Lamps (DRL)/
Automatic Headlamp SystemDaytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required
on all vehicles first sold in Canada.
The DRL system makes the low-beam headlamps
come on at a reduced brightness when the following
conditions are met:•
The ignition is in the ON/RUN position.
•
The exterior lamps control is in AUTO.
•
The engine is running.
When the DRL are on, the regular headlamps, taillamps,
sidemarker, and other lamps are not on. The instrument
panel and cluster are also not on.
The headlamps automatically change from DRL to
the regular headlamps depending on the darkness of
the surroundings. The other lamps that come on with
the headlamps will also come on.
When it is bright enough outside, the headlamps go off
and the DRL come on.
The regular headlamp system should be turned on
when needed.
Do not cover the light sensor on top of the instrument
panel because it works with the DRL.

Passenger Safety Belt Reminder LightSeveral seconds after the engine is started, a chime
sounds for several seconds to remind the front
passenger to buckle their safety belt. This only occurs
if the passenger airbag is enabled. SeePassenger
Sensing System on page 2-66for more information.
The passenger safety belt light, located on the instrument
panel, comes on and stays on for several seconds and
then flashes for several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger safety belt is buckled, neither the
chime nor the light comes on.
The front passenger safety belt warning light and chime
may turn on if an object is put on the seat such as a
briefcase, handbag, grocery bag, laptop or other
electronic device. To turn off the warning light and or
chime, remove the object from the seat or buckle the
safety belt.
Airbag Readiness LightThe system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check includes
the airbag sensor, the pretensioners, the airbag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 2-56.
The airbag readiness light
flashes for a few seconds
when the engine is started.
If the light does not come
on then, have it fixed
immediately.

(TPMS), this message displays when the TPMS is
re-learning the tire positions on your vehicle. The tire
positions must be re-learned after rotating the tires or
after replacing a tire or sensor. SeeTire Inspection and
Rotation on page 6-65,Tire Pressure Monitor System on
page 6-60, andInflation - Tire Pressure on page 6-59for
more information.
4-49

How to CheckUse a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly
inflated simply by looking at them. Radial tires
may look properly inflated even when they are
under-inflated. Check the tire’s inflation pressure
when the tires are cold. Cold means your vehicle
has been sitting for at least three hours or driven
no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage firmly onto the valve to
get a pressure measurement. If the cold tire
inflation pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
inflation pressure is low, add air until you reach
the recommended amount.
If you overfill the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor SystemThe 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 inflated to the inflation
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire inflation
pressure label, you should determine the proper
tire inflation 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 significantly under-inflated.
6-60

Tire Pressure Monitor OperationThis vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver when
a low tire pressure condition exists. TPMS sensors are
mounted onto each tire and wheel assembly, excluding
the spare tire and wheel assembly. The TPMS sensors
monitor the air pressure in the vehicle’s tires and
transmits the tire pressure readings to a receiver located
in the vehicle.
When a low tire pressure
condition is detected, the
TPMS illuminates the
low tire pressure warning
light located on the
instrument panel cluster.
At the same time a message to check the pressure in a
specific tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light and the
DIC warning message come on at each ignition cycle
until the tires are inflated to the correct inflation pressure.
Using the DIC, tire pressure levels can be viewed by the
driver. For additional information and details about the
DIC operation and displays seeDIC Operation and
Displays on page 4-37andDIC Warnings and Messages
on page 4-44.The low tire pressure warning light may come on in
cool weather when the vehicle is first started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inflated to the proper pressure.
A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle’s original
equipment tires and the correct inflation pressure for
your vehicle’s tires when they are cold. SeeLoading the
Vehicle on page 5-20, for an example of the Tire and
Loading Information label and its location on your
vehicle. Also seeInflation - Tire Pressure on page 6-59.
Your vehicle’s TPMS can warn you about a low tire
pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation
on page 6-65andTires on page 6-51.
Notice:Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not
covered by your warranty. Do not use liquid tire
sealants.6-62
