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.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 43

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

•The rain sensing feature may not function properly
when ice, or dried salt water is present on the wind-
shield.
•Use of Rain-Xor products containing wax or silicone
may reduce rain sensor performance.
•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.
The rain sensing system has protection features for the
wiper blades and arms, and will not operate under the
following conditions:
•Low Temperature Wipe Inhibit—When the ignition
is first switched ON and the vehicle is stationary, and
the outside temperature is below 32°F(0°C), the rain
sensing feature will be suspended unless the wiper
switch is moved, or the vehicle speed becomes greater
than 0 mph (0 km/h), or the outside temperature rises
above freezing.
•Neutral Wipe Inhibit—When the ignition is ON and
while the transmission shift lever is in the N (Neutral)
position, and the vehicle speed is less than 5 mph (8
k/mh), the rain sensing feature will be suspended
unless the wiper switch is moved or the shift lever is
moved out of the N (Neutral) position.
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.
Headlights On With Wipers (Available with Auto
Headlights Only)
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)—If equipped. Refer to”Headlights On With
Wipers”in the Electronic Vehicle Information Center
section of this manual for details.

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.WARNING!
Drivers must be careful when backing up even when
using the Rear Park Assist System. Always check
carefully behind your vehicle, look behind you, and
be sure to check for pedestrians, other vehicles,
obstructions, and blind spots before backing up.
Failure to do so can result in serious personal injury
or death.
The display contains two sets of yellow and red LEDs
that can be viewed from the driver seat using the rear
view mirror. Each side of the vehicle has its own warning
LEDs. The system provides a visual warning by illumi-
nating one or more yellow LEDs as the vehicle gets closer
to the object. As the vehicle continues to approaches the
object, one red LED is illuminated and the system emits
a series of short beeps. The tone will remain constant and
both red LEDs are illuminated once the vehicle is within
12 inches (30.5 cm) of the object.

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

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 button
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 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.

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.
Automatic Temperature Controls
196 UNDERSTANDING YOUR INSTRUMENT PANEL

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
heating system. Should the desired comfort level require
air conditioning, the system will automatically make the
adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the OFF position on the fan control stops the system
completely and closes the outside air intake.
72°F (22°C) is the recommended setting for maximum
comfort for the average person, however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic control operation.The air conditioning in this system is automatic.
Pressing this button while in AUTO mode will
cause the LED to flash three times and remain off.
This indicates that the system is in AUTO and requesting
the air conditioning is not necessary.
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.

TIRE PRESSURE MONITOR SYSTEM—IF
EQUIPPED
Tire Pressure Monitoring—Base System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels (EXCLUDING THE SPARE
TIRE). Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the Re-
ceiver Module.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more
tire pressures is low. The Tire Pressure Monitoring Tell-
tale Light will flash on and off for 10 to 60 seconds when
a system fault is detected. The flash cycle will repeat
every ten minutes or until the fault condition is removed
and reset.The Tire Pressure Monitoring System consists of the
following components:
•Receiver Module
•4 Wheel Sensors
•Tire Pressure Monitoring Telltale Light
NOTE:For vehicles with optional wheel/tire sizes and
significantly different tire placard pressures, the placard
pressure value and the low-pressure threshold value is
re-programmable at your authorized dealer to accommo-
date the customer selected wheel/tire combinations rec-
ommended by DaimlerChrysler.
