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 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
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
object were moving.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash speed than
if the vehicle hits an object 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.

Passenger Sensing System
If your instrument panel has one of the indicators
pictured in the following illustrations, then your vehicle
has a passenger sensing system. The passenger airbag
status indicator on the instrument panel will be visible
when you turn your ignition key to ON or START.
The word ON and the word OFF or the symbol for on
and the symbol for off, will be visible during the system
check. If you use remote start to start your 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 the symbol for off will be visible. SeePassenger
Airbag Status Indicator on page 3-35.The passenger sensing system will turn off the right
front passenger’s frontal airbag under certain conditions.
The driver’s airbag and the side airbags are not part
of the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat. 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.

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
inate 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 minutes after the ignition key is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an
airbag when it inates. 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 qualied 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 Service 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.

The DRL system will make both front turn signal lamps
turn on when the following conditions are met:
The ignition is on.
The exterior lamp control is turned to AUTO. In
addition, Canadian vehicles DRL will also turn
on if you have turned on your parking lamps.
The light sensor detects daytime light.
The shift lever is not in PARK (P).
While the DRL system is on, the taillamps, sidemarker
lamps, and instrument panel lights will not be
illuminated.
The DRL system will be off any time your vehicle is
in PARK (P). The DRL system on U.S. vehicles can also
be turned off by using the off/on switch for one ignition
cycle.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Automatic Headlamp System
When it is dark enough outside, your automatic system
will turn on your headlamps at the normal brightness
along with other lamps such as the taillamps, sidemarker,
parking lamps, instrument panel lights, and interior switch
backlighting.
Your vehicle has a light sensor on top of the instrument
panel. Make sure it is not covered, or the headlamps
may remain on when you do not need them.
The system may also be on 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 automatic lamp control
system so that driving under bridges or bright overhead
street lights does not affect the system. The automatic
lamp control system will only be affected when the
light sensor sees a change in lighting lasting longer
than this delay.
If you start your vehicle in a dark garage, the automatic
lamp system will come on immediately. Once you
leave the garage, it will take about one minute for
the automatic lamp 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 3-19.
To idle your vehicle with the system off, turn the
ignition on and rotate the exterior light switch to the
off/on position. For Canadian vehicles, the transaxle
must stay in PARK (P) for this function.
As with any vehicle, you should turn on the regular
headlamps when you need them.Fog Lamps
If your vehicle has this
feature, the button for the
fog lamps is located on
the instrument panel, to the
left of the steering wheel.
If your vehicle has fog lamps, the ignition must be on.
Push the button to turn the fog lamps on. An indicator
light in the button will glow when the fog lamps are
on. Push the button again to turn the fog lamps off.
The fog lamps will turn off while the high-beam
headlamps are turned on.
Some localities have laws that require the headlamps
to be on along with the fog lamps.

Automatic Climate Control System
If your vehicle has this system, you can automatically
control the heating, cooling and ventilation in your
vehicle.
Automatic Operation
AUTO (Automatic):Select AUTO on both the fan
speed control and the air delivery mode control knobs to
activate the automatic system. When automatic operation
is active the system will control the inside temperature
and air delivery.Use the steps below to place the entire system in
automatic mode:
1. Place the fan knob and the mode knob to AUTO.
The display will now show the current set
temperature. When auto is selected, the air
conditioning operation and air inlet will be
automatically controlled. The air conditioning
compressor will run when the outside temperature
is over about 40°F (4°C). The air inlet will normally
be set to outside air. If it’s hot outside, the air
inlet may automatically switch to recirculate inside
air to help quickly cool down your vehicle.
2. Set the temperature.
To nd your comfort setting, start with an initial
temperature setting and allow about 20 minutes
for the system to regulate. Press the up or
down arrow temperature buttons to adjust the
temperature setting as necessary. If you choose
the temperature setting of 60°F (15°C) the
system will remain at the maximum cooling setting.
If you choose the temperature setting of 90°F
(32°C) the system will remain at the maximum
heat setting. Choosing either maximum setting will
not cause the vehicle to heat or cool any faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield.
This sensor regulates air temperature based on
sun load, and also turns on your headlamps.
3-27

Also be careful not to cover the sensor grille on
the lower right side of the climate control faceplate.
This senses the inside vehicle temperature
needed for proper regulation.
To avoid blowing cold air at start-up in cold weather,
the system will delay turning on the fan until
warm air is available. The length of delay depends
on the engine coolant temperature. Turning the
fan knob will override this delay and change the
fan to a selected speed.
If your vehicle has the remote start feature, the climate
control display will initially show “AS” in place of the
temperature to indicate the remote start has been
activated. The system will automatically regulate the
temperature.Manual Operation
You may manually adjust the air delivery mode or
fan speed.
9(Off):Select this position on the fan knob to turn
off the entire climate control system. Outside air will
still enter the vehicle, and will be directed to the
oor. This direction can be changed by changing the
mode position. The temperature can also be adjusted
using either the up or down arrow temperature buttons.
9(Fan):The knob with the fan symbol allows you
to manually adjust the fan speed.
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets, and the remaining air to
the oor outlets.

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, seeAirbag System on page 1-60.
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 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.
The airbag readiness light should ash for a
few seconds when you turn the ignition key to ON.
If the light doesn’t come on then, have it xed so it
will be ready to warn you if there is a problem.
