Airbag System Components
The front airbag system consists of the following:
•Airbag Control Module
•AIRBAGReadiness Light
•PASS AIRBAG OFFReadiness Light
•Front Impact Accelerometer sensors
•Side Impact Accelerometer sensors
•Driver Airbag
•Passenger Airbag
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Knee Impact Bolsters
The side curtain airbag system, on vehicles so equipped,
consists of the following:
•Airbag Control Module
•AIRBAGReadiness Light
•Left and Right Side Curtain Airbags Above Side
Windows
•Left and Right Side Impact Sensors
•Interconnection Wiring
How The Airbag System Works
•
The airbag control module determines if a frontal
collision is severe enough to require the airbags to
inflate. The control module receives the level of colli-
sion severity, determines the proper level of airbag to
be deployed. The frontal airbag inflators are designed
to provide three different rates of airbag inflation.
•The airbag control module will not detect a rollover.
•The airbag control module also monitors the readiness
of the electronic parts of the system whenever the
ignition switch is in the START or ON positions. These
include all of the items listed above except the knee
bolster, the instrument panel, and the steering wheel

NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
Side Airbag System
The airbag control module determines if a side collision is
severe enough to require the airbag to inflate. The control
module receives the level of collision severity from the
side impact sensors. The airbag control module will not
detect rollover or rear impacts.
The side impact SRS Airbags are designed to activate
only in certain side collisions. When the airbag control
module detects a collision requiring the side curtain
airbags to inflate, it signals the inflators on the crash side
of the vehicle. A quantity of nontoxic gas is generated to
inflate the side curtain airbags. The inflating side curtain
airbag pushes the outside edge of the headliner out of the
way and inflates (in about the same time it takes to blink
your eyes) with enough force to injure you if you are not
belted and seated properly, or if items are positioned in
the area where the side curtain airbag inflates. This
especially applies to children. The side curtain airbag is
only about 3
1⁄2inches (83⁄4cm) thick when it is inflated.
Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured because the airbags are not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or
the upper right side of the instrument panel. Do
not modify the front bumper, vehicle body struc-
ture, or frame.
•You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee impact bolster.
•It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has airbags.

* Since the system senses weight, some small objects
will turn the PAD Indicator Light on.
The OCS classifies an occupant using weight sensors
mounted in the base of the front passenger seat. Any
weight on the seat will be sensed by the system. Objects
hanging on the seat or other passengers pushing down
on the seat will also be sensed. The weight of an adult
will cause the system to turn the airbag on. In this case,
the OCS has classified the occupant of the seat as an
adult. An adult occupant needs to sit in a normal position
(with their feet on or near the floor) in order to be
properly classified.Drivers and adult passengers should verify that the PAD
Indicator Light is not illuminated when they are riding in
the front passenger seat. If an adult occupant’s weight is
transferred to another part of the vehicle (like the door or
instrument panel), the weight sensors in the seat may not
properly classify the occupant. Objects lodged under the
seat or between the seat and the center console can
prevent the occupant’s weight from being measured
properly and may result in the occupant being improp-
erly classified.
If the front passenger seat is damaged in any way, it
should only be serviced by an authorized dealer. If the
seat is removed (or even if the seat attachment bolts are
loosened or tightened in any way), take the vehicle to an
authorized dealer.
If the is a fault present in the OCS, the Airbag Warning
Light (a red light located in the center of the instrument
cluster directly in front of the driver) will be turned on.
This indicates that you should take the vehicle to an
authorized dealer. The Airbag Warning Light is turned on
whenever there is fault that can affect the operation of the
airbag system. If there is a fault present in the OCS, both
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

the PAD Indicator Light and the Airbag Warning Light
are illuminated to show that the passenger airbag is
turned off until the fault is cleared. If an object is lodged
under the seat and interferes with operation of the weight
sensors, a fault will occur which turns on both the PAD
Indicator Light and the Airbag Warning Light. Once the
lodged object is removed, the fault will be automatically
cleared after a short period of time.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the rightside of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
may be possible based on collision severity and occu-
pant size. The steering wheel hub trim cover and the
upper right side of the instrument panel separate and
fold out of the way as the bags inflate to their full size.
The bags fully inflate in about 50 - 70 milliseconds.
This is about half of the time it takes to blink your eyes.
The bags then quickly deflate while helping to restrain
the driver and front passenger. The driver’s front
airbag gas is vented through vent holes in the sides of
the airbag. The passenger’s front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.
•TheOccupant Classification Module (OCM)is lo-
cated beneath the front passenger seat. The OCM
classifies the occupant into categories based on the
measurements made by the seat weight sensors. The
OCM communicates with the Occupant Restraint Con-
troller (ORC). The ORC uses the occupant category to

determine whether the front passenger airbag should
be turned off. It also determines the rate of airbag
inflation during a collision.
•ThePassenger Airbag Disabled (PAD) Indicator
Lightindicates to the driver and passenger when the
airbag is turned OFF. In the presence of a properly
seated occupant, when the PAD indicator light is
illuminated, the airbag is OFF. Also, when the Occu-
pant Classification System detects either an empty seat
or a weight less than the predetermined threshold, the
ORC will not illuminate the PAD indicator light even
though the airbag is turned OFF.
•Your vehicle has fourWeight Sensorslocated between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System(OCS) to properly classify the front passenger and calcu-
late the proper airbag deployment. Do not make any
modifications to the front passenger seat components,
assembly, or to the seat cover.
WARNING!
Unapproved modifications or service procedures to
the front passenger seat assembly, its related compo-
nents, or seat cover may inadvertently change the
airbag deployment in case of a frontal crash. THIS
COULD RESULT IN DEATH OR SERIOUS INJURY
TO THE FRONT SEAT PASSENGER IF THE VE-
HICLE IS INVOLVED IN AN ACCIDENT. A modi-
fied vehicle may not comply with required Federal
Motor Vehicle Safety Standards (FMVSS).
The following requirements must be strictly adhered to:
•Do not modify the front passenger seat assembly or
components in any way.
•Do not modify the front seat center console or center
position seat in any way.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The ESP enhances directional control and reduces driving
wheel spin of the vehicle under various driving condi-
tions. The system operates when the vehicle speed is
greater than 7.8 mph (12.6 km/h).
The ESP system corrects for over/understeering of the
vehicle by applying brakes to the appropriate wheel.
Engine torque is also limited.
The ESP warning light, located in the instru-
ment cluster, starts to flash as soon as the ESP
system sensor’s information varies from the
driver’s intended path. The ESP warning light
also flashes when traction control is activated. If the ESP
warning light begins to flash during acceleration, ease up
on the accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the prevailing
road conditions. When the ESP warning light is illumi-
nated continuously, the ESP is switched off. To return to
the enhanced vehicle stability offered by ESP, press the
ESP switch (the ESP warning light in the instrument
cluster goes out). Avoid spinning one drive wheel. This
may cause serious damage to the drive train.To improve the vehicle’s traction when driving with
snow chains, or starting off in deep snow, sand or gravel,
switch off the ESP system by pressing the ESP switch.
With the ESP system switched off, the engine torque
reduction feature is cancelled. Therefore, the enhanced
vehicle stability offered by ESP is unavailable. ESP al-
ways operates under braking, even with the switch in the
OFF position. When the ESP system is disabled (if one
drive wheel loses traction and begins to spin) the brake is
applied by the ESP system to control wheel slip. This

The operation of the Brake Warning Light can be checked
by turning the ignition switch from the OFF position to
the ON position. The light should illuminate for approxi-
mately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is detected.
If the light does not illuminate, have the light inspected
by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
21. Vehicle Theft Alarm (VTA) Indicator Light
The VTA indicator Light flashes rapidly when the VTA is
arming, and slowly when the VTA is armed. (See page 24
for more information.)
22. Tire Pressure Monitor Warning Light—If
Equipped
This light will turn on continuously when
there is a Low tire pressure condition. The
light will also turn on if a problem exist with
any tire sensor. When a system fault isdetected, the indicator light will flash repetitively for
ten seconds. The flash cycle will repeat every ten
minutes or until the fault condition is removed and
reset. The light will remain on or flashing until the tire
pressure is properly set or the problem with the sensor
is corrected.
This light will turn on momentarily as a bulb check when
the engine is started.
When the tire pressure monitoring system warning light
is lit, one or more of your tires is significantly underin-
flated. You should stop and check your tires as soon as
possible, and inflate them to the proper pressure as
indicated on the Tire and Loading Information Placard.
Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla-
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
Each tire, including the spare, should be checked
monthly when cold and set to the recommended inflation
pressure as specified in the tire and loading information
placard.

Compass Display
The compass readings indicate the direction
the vehicle is facing. Press and release the
compass button to display one of eight com-
pass readings and the outside temperature.
Automatic Compass Calibration
This compass is self calibrating, which eliminates the
need to manually set the compass. When the vehicle is
new, the compass may appear erratic and the EVIC will
display“CAL”until the compass is calibrated. You may
also calibrate the compass by completing one or more
360°turns (in an area free from large metal or metallic
objects) until the“CAL”message displayed in the EVIC
turns off. The compass will now function normally.
Manual Compass Calibration
If the compass appears erratic and the“CAL”message
does not appear in the EVIC display, you must put the
compass into the Calibration Mode manually as follows:To put into a Calibration Mode:Turn on the ignition
switch. Then, press and hold the compass button for
approximately 2 seconds. Then, press the SCROLL but-
ton until“Calibrate Compass”displays in the EVIC.
Then, press and release the FUNCTION SELECT button
to start the calibration. The message“CAL”will display
in the EVIC. Complete one or more 360°turns (in an area
free from large metal or metallic objects) until the“CAL”
message turns off. The compass will now function nor-
mally.
Compass Variance
Compass Variance is the difference between magnetic
North and Geographic North. In some areas of the
country, the difference between magnetic and geographic
North is great enough to cause the compass to give false
readings. If this occurs, the compass variance must be set.
NOTE:Magnetic materials should be kept away from
the overhead console. This is where the compass sensor is
located.

Recirculation
The recirculation feature can be selected with
the mode control knob. You may choose
between Bi-Level Recirculation and Panel
Recirculation air outlets while in this mode.
Normally, air enters from outside the vehicle. How-
ever, when in Recirculation mode air inside the vehicle
is re-used. Use this mode to rapidly cool the inside of
the vehicle. The Recirculation mode can also be used
to temporarily block out outside odors, smoke, and
dust.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Automatic Temperature Control—If Equipped
The Infrared Dual-Zone Climate Control System auto-
matically maintains the interior comfort level desired by
the driver and passenger. This is accomplished by a dual
sun-sensor in the top of the instrument panel, and an
infrared sensor located in the face of the control unit.
There are also various sensors monitored by this system
which take account for vehicle speed, A/C pressure,
outside temperature, and engine cooling temperature.
The infrared sensor independently measures the surface
temperature of the driver and passenger. Based on the
sensor input, the system automatically adjusts the air
flow temperature, the air flow volume, and amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
190 UNDERSTANDING YOUR INSTRUMENT PANEL

The system will automatically control recircu-
lation. However, pressing this button will tem-
porarily put the system in recirculation mode
(ten minutes). This can be used when outside
conditions such as smoke, odors, dust, or high humidity
are present. This will cause the LED to illuminate. After
ten minutes the system will return to normal AUTO
mode function and the LED will turn off.
NOTE:
•
The surface of the climate control panel, and the top
center of the instrument panel should be kept free of
debris due to the location of the climate control
sensors. Mud on the windshield may also cause poor
operation of this system.
•Most of the time, when in Automatic operation, you
can temporarily put the system into recirculation
mode by pressing the Recirc button. However, under
certain conditions in automatic the system is blowing
air out of the defrost vents. When these conditions arepresent and the Recirc button is pressed the indicator
will flash and remain off. This tells you that you are
unable to go into recirculation mode at this time. If you
would like to go to Recirculation mode, you must first
move your mode knob to panel, panel/floor or floor,
then hit the recirc button. This feature will reduce the
possibility of window fogging.
Manual Operation
This system offers a full complement of manual override
features which consist of Blower Preferred Automatic,
Mode Preferred Automatic, or Blower and Mode Pre-
ferred Automatic. This means the customer can override
the blower, the mode, or both. There is a manual blower
range used when the AUTO setting is not desired. The
left control can be set to any fixed blower speed by
rotating the knob.
NOTE:Please read the Automatic Temperature Control
Operation Chart below for details.
