How The Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. The front airbag inflators are de-
signed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC may
also modify the rate of inflation based on the occupant
size provided by the Occupant Classification Module.
The ORC will not detect roll over.
•The ORC 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 instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK position, in the ACC position, or
not in the ignition, the airbags are not on and will not
inflate.

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. Reclining the seat back too far may
change how an occupant is classified by the OCS.
Drivers and adult passengers should verify that the PAD
Indicator Light is not illuminated when an adult is 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. Ensure that the front passenger seat back
does not touch anything placed on the back seat becausethis can also affect occupant classification. Also, if you
fold down the rear seat check to be sure it doesn’t touch
the front passenger seat.
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 there 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
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 right
side 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.
•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.
•TheSide Impact SRS Side Curtain Airbagare de-
signed to activate only in certain side collisions. When
the ORC (with side impact option) detects a collision
requiring the side curtain airbag 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
airbag. The inflating side curtain airbag pushes the
outside edge of the headliner out of the way and
covers the window. The airbag inflates in about 30

This system is used to help drivers determine if an
obstacle is in the way of the vehicle while it is backing up
in addition to the use of inside rearview and outside
mirrors.
When the driver selects Reverse the system scans for
objects behind the vehicle using four sensors located in
the rear bumper. Objects can be detected from up to 71
inches (180 cm). A warning display above the rear
window provides both visible and audible warnings
indicating the range of the object.

•Use of Rain-Xor products containing wax or silicone
may reduce rain sensor performance.
•The rain sensing system will not operate when the
engine is running, the gear selector is in the PARK
position, and the outside temperature is below freez-
ing. This is done to protect the wiper blades from
damage. Place the gear selector in the DRIVE position
to allow the rain sensing feature to operate.
•A customer programmable feature in the Electronic
Vehicle Information Center (EVIC) allows the Rain
Sense feature to be turned off. Refer to “Personal
Settings” in the Electronic Vehicle Information Center
section of this manual for details.
Mist Feature
Push the wiper lever in to activate a single wipe to clear
off road mist or spray from a passing vehicle. As long as
the lever is pushed in, the wipers will continue to
operate.
Headlamps On With Wipers
The headlights will turn on approximately 10 seconds
after the wipers are turned on if the headlight switch is
placed in the AUTO position. The headlights will also
turn off when the wipers are turned off if they were
turned on by this feature. This feature can be turned on or
off using the Electronic Vehicle Information Center
(EVIC). Refer to ”Headlamps On With Wipers” in the
Electronic Vehicle Information Center section of this
manual for details.
Windshield Wiper Operation
Rotate the end of the lever to the second detent for Low
speed wiper operation, or to the third detent for High
speed operation.
Intermittent Wiper System
Use the intermittent wiper when weather conditions
make a single wiping cycle, with a variable pause be-
tween cycles, desirable. Rotate the end of the lever to the
first detent position, then turn the end of the lever to
select the desired delay interval. There are 6 possible

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

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.
To put into a Calibration Mode:Turn on the ignition
switch. Press and hold the compass button for approxi-
mately 2 seconds. Use the SCROLL buttons until “Cali-
brate Compass” is highlighted. Press and release the
FUNCTION SELECT button to start the calibration. The
message “CAL” will appear in the EVIC. Complete one
or more 360° turns in an area free from large metal objects
until the “CAL” message turns off. The compass will now
function normally.
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.

CLIMATE CONTROLS
Automatic Temperature Control
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.Operation of the system is quite simple. Begin by turning
the right mode knob to AUTO, and place the blower
control (left knob) to either LO AUTO or HI AUTO. The
LO AUTO position should be used for front seat occu-
pants only. The HI AUTO position should be used when
more air flow is desired, or when rear seat occupants are
present. Dial in the temperature you would like the
system to maintain by rotating the driver’s or passenger’s
control knob. Once the comfort level is selected the
system will maintain that level automatically using the
