When Should an Airbag In ate?
The driver’s and right front passenger’s frontal airbags
are designed to in ate in moderate to severe frontal
or near-frontal crashes. But they are designed to in ate
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 in ate 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 is equipped with electronic frontal sensors,
which help the sensing system distinguish between a
moderate frontal impact and a more severe frontal
impact. For moderate frontal impacts, these airbags
in ate 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 11 to 18 mph (17.5 to
28.9 km/h), and the threshold level for a full deployment
is about 18 to 23 mph (28.9 to 37 km/h). (The threshold
level can vary, however, with speci c vehicle design,
so that it can be somewhat above or below this range.)
Frontal airbags may in ate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbags
could in ate at a different crash speed than if the
object were moving.
If the vehicle hits an object that deforms, the
airbags could in ate at a different crash speed than
if the object does not deform.
If the vehicle hits a narrow object (like a pole) the
airbags could in ate 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 in ate at a different crash speed
than if the vehicle goes straight into the object.

The frontal airbags (driver and right front passenger)
are not intended to in ate during vehicle rollovers,
rear impacts, or in many side impacts.
Your vehicle has seat position sensors which enable the
sensing system to monitor the position of the driver’s
seat and the right front passenger’s seat. Seat position
sensors provide information that is used to determine
if the airbags should deploy at a reduced level or at
full deployment.
Your vehicle may or may not have a roof-mounted side
impact airbag and rollover sensor. SeeAirbag System
on page 1-49. These “rollover capable” airbags are
intended to in ate in moderate to severe side crashes
or during a rollover. A roof-mounted side impact
airbag will in ate if the crash severity is above the
system’s designed “threshold level.” The threshold level
can vary with speci c vehicle design. Roof-mounted
side impact airbags are not intended to in ate in frontal
or near-frontal impacts, or rear impacts.In any particular crash, no one can say whether an
airbag should have in ated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, in ation is determined by
what the vehicle hits, the angle of the impact, and how
quickly the vehicle slows down. For roof-mounted
side impact airbags, in ation is determined by the
location and severity of the impact.
The airbag system is designed to work properly under a
wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. SeeOff-Road
Driving on page 4-17for tips on off-road driving.

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 in ate) 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 in ates. This is because
the back of the rear-facing child restraint
would be very close to the in ating 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. General Motors recommends 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.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. You do not want the system to
in ate while someone is working on your vehicle.
Your dealer and the service manual have information
about servicing your vehicle and the airbag system.
To purchase a service manual, seeService Publications
Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
airbag can still in ate during improper service.
You can be injured if you are close to an
airbag when it in ates. Avoid yellow wires,
wires wrapped with yellow tape or 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 quali ed to do so.
The airbag system does not need regular maintenance.
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.

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 DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P) if you have an
automatic transmission.
The light sensor determines it is daytime.
When the DRL are on, only the DRLs will be on. The
other lamps will not be on. The instrument panel will not
be lit up either. For vehicles rst sold in Canada, if
parking lamps are manually turned on, DRL will stay on.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
To turn off the DRL, seeExterior Lamps on page 3-14.
Vehicles rst sold in Canada cannot turn off DRL
unless certain conditions are met. SeeExterior Lamps
on page 3-14.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps, roof marker
lamps and the instrument panel lights. The radio
lights will become more dim when the headlights are off
compared to when the headlights are on.
Your vehicle has a light sensor located on the top of the
instrument panel. Be sure it is not covered, or the
system will be on whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp system so that driving
under bridges or bright overhead street lights does not
affect the system. The DRL and automatic headlamp
system will only be affected when the light sensor sees a
change in lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave the garage, it will take approximately one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure your
instrument panel brightness control is in the full bright
position. SeeInstrument Panel Brightness on page 3-18.

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 sensors, the
airbag modules, the wiring and the crash sensing and
diagnostic module. For more information on the
airbag systems, seeAirbag System on page 1-49.
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.
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 after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not in ate in a crash, or they
could even in ate 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.
The airbag readiness light should ash for a few
seconds when you turn the ignition key to ON. If the
light does not come on then, have it xed so it will
be ready to warn you if there is a problem.

How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly in ated
simply by looking at them. Radial tires may look properly
in ated even when they are underin ated. Check the
tire’s in ation 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 rmly onto the valve to get a pressure
measurement. If the cold tire in ation pressure matches
the recommended pressure on the Tire and Loading
Information label, no further adjustment is necessary.
If the in ation pressure is low, add air until you reach the
recommended amount.
If you over ll the tire, release air by pushing on the
metal stem in the center of the tire valve. Recheck 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 System
Your vehicle is equipped with a Tire Pressure Monitor
System (TPMS). This system uses radio and sensor
technology to check tire pressure levels. TPMS sensors
are mounted onto each tire and wheel assembly on
your vehicle, including the spare tire. The TPMS sensors
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 in ated to the in ation
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire in ation pressure label.
When the low tire pressure
telltale is illuminated, one
or more of your tires is
signi cantly under-in ated.
You should stop and check your tires as soon as
possible, and in ate them to the proper pressure. Driving
on a signi cantly under-in ated tire causes the tire to
overheat and can lead to tire failure. Under-in ation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
5-61
Page 328 of 410
When a low tire pressure condition is detected, the
TPMS will illuminate the low tire pressure warning
symbol on the instrument panel cluster, and at the same
time display the LOW TIRE message on the Driver
Information Center (DIC). The message will appear at
each ignition cycle until the tires are in ated to the
correct in ation pressure. For additional information and
details about the DIC operation and displays seeDIC
Controls and Displays on page 3-41andDIC Warnings
and Messages on page 3-44.
A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle’s original
equipment tires and the correct in ation pressure for
your vehicle’s tires when they are cold. SeeLoading
Your Vehicle on page 4-52, for an example of the
tire information label and its location on your vehicle.
Also seeIn ation - Tire Pressure on page 5-60for
additional information.
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 5-64,When It Is Time for New Tires on page 5-65,
andTires on page 5-53.Notice:Do not use a tire sealant if your vehicle is
equipped with Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
The SERV (Service) TPM message is displayed when
the TPMS system is malfunctioning. One or more
missing or inoperable TPMS sensors will cause the
service tire monitor message to be displayed. See your
dealer for service,
TPMS Sensor Identi cation Codes
Each TPMS sensor has a unique identi cation code.
Any time you rotate your vehicle’s tires or replace one or
more of the TPM sensors, the identi cation codes will
need to be matched to the new tire/wheel position.
The sensors are matched to the tire/wheel positions in
the following order: left front (LF), right front (RF),
right rear (RR) and left rear (LR).
You will have one minute to match the rst tire/wheel
position, and ve minutes overall to match all four
tire/wheel positions. If it takes longer than one minute,
to match the rst tire and wheel, or more than ve
minutes to match all four tire and wheel positions the
matching process stops and you will need to start over.
5-62
Page 329 of 410
The TPM sensor matching procedure is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON with the engine off.
3. Turn the exterior lamp switch from AUTO to
ON four times within three seconds. A double horn
chirp will sound and the TPMS low tire warning
light will begin to ash. The double horn chirp and
ashing TPMS warning light indicates the TPM
matching process has started. The TPMS warning
light should continue ashing throughout the
matching procedure. The SERV TPM message will
be displayed on the Driver Information Center (DIC).
4. Start with the left (driver’s side) front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for 10 seconds,
then stop and listen for a single horn chirp.
The single horn chirp should sound within
15 seconds, con rming that the sensor identi cation
code has been matched to this tire and wheel
position. If you do not hear the con rming single
horn chirp, you will need to start over with step
number one. To let air-pressure out of a tire you can
use the pointy end of the valve cap, a pencil-style
air pressure gage or a key.6. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in Step 5.
7. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in Step 5.
8. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in Step 5.
9. After hearing the con rming horn chirp for the left
rear tire, check to see if the TPMS warning light is
still ashing. If yes, turn the ignition switch to LOCK.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.
