WARNING!
²Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won't deploy at all.
Always wear your seat belts even though you
have airbags.
²Being too close to the steering wheel or instru-
ment panel during front airbag deployment could
cause serious injury. Airbags need room to inflate.
Sit back, comfortably extending your arms to
reach the steering wheel or instrument panel.
²If the vehicle has side airbags, they also need
room to inflate. Do not lean against the door. Sit
upright in the center of the seat.
The front airbag system consists of the following:
²Occupant Restraint Controller
²Side Remote Acceleration Sensors (If Equipped)
²Airbag Warning Light
²Driver Airbag
²Passenger Airbag
²Front Seat Mounted Side Airbags (If equipped)
²Steering Wheel and Column
²Instrument Panel
²Interconnecting Wiring
²Knee Impact Bolsters
²Driver Inflatable Knee Blocker
²Front Acceleration Sensors

How The Airbag System Works
²
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 RUN positions. These include all of the
items listed above except the steering wheel and
column, and knee bolsters. If the key is in the OFF
position, in the ACC position, or not in the ignition,
the airbags are not on and will not inflate.
During a moderate-to-severe rear impact the ORC may
deploy the seat belt pretensioners alone.
Also, the ORC turns on the AIRBAG warning
light and PAD indicator light in the instrument
panel for 6 to 8 seconds for a self-check when
the ignition is first turned on. After the self-
check, the AIRBAG warning light will turn off. The PAD
indicator light will function normally (Refer to9Passen-
ger Airbag Disable (PAD) Indicator Light9in this section).
If the ORC detects a malfunction in any part of the
system, it turns on the AIRBAG warning light either
momentarily or continuously. A single chime will sound
if the light comes on again after initial start up.

WARNING!
Ignoring the AIRBAG light in your instrument panel
could mean you won't have the airbags to protect
you in a collision. If the light does not come on, stays
on after you start the vehicle, or if it comes on as you
drive, have the airbag system checked right away.
²TheOccupant Classification System (OCS)is part of
a Federally regulated safety system required for this
vehicle. It is designed to turn off the front passenger
airbag for occupants that weigh less than a very small
adult.
NOTE:Children 12 years and under should always ride
buckled up in a rear seat in an appropriate child restraint.
²The 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 push-
ing 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.
²ThePassenger Airbag Disable (PAD) Indicator Light
(an amber light located in the center of the instrument
panel) tells the driver and front passenger when the
front passenger airbag is turned off. The PAD Indica-
tor lamp illuminates the words9PASS AIR BAG OFF9
to show that the front passenger airbag will not inflate
during a collision requiring airbags. When the right
front passenger seat is empty or when very light
objects are placed on the seat, the passenger air bag

* Since the system senses weight, some small objects
will turn the PAD Indicator Light on.
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 dooror 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 second row of
seats because this can also affect occupant classification.
Also, if you fold down the seats in the second row check
to be sure they don'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.
96 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
²TheDriver 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 ratesmay 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.
²TheOccupant 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.
²Your vehicle has fourWeight Sensorslocated between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
²TheSide Impact (SRS) Seat Mounted Side Airbags
(If equipped)are designed to activate only in certain
side collisions. The ORC module determines if a side
collision is severe enough to require the side airbags to
inflate. The side airbag control module will not detect
roll over, front or rear collisions.
The ORC Module monitors the readiness of the elec-
tronic parts of the system whenever the ignition switch
is in the START or ON positions. These include all of
the items previously mentioned.In moderate to severe side collisions, the side airbag
inflator on the crash side of the vehicle is triggered,
releasing a quantity of nontoxic gas. The inflating side
airbag exits through the seat seam into the space between
the occupant and the door. The side airbag moves at a
very high speed and with such a high force, that it could
injure you if you are not seated properly, or if items are
positioned in the area where the side airbag inflates. This
especially applies to children.
²When the ORC and the impact sensors detect a
collision requiring theDriver Inflatable Knee Blocker
, it signals the inflator unit. A quantity of nontoxic gas
is generated to inflate the Driver Inflatable Knee
Blocker. The Driver Inflatable Knee Blocker inflates
rearward towards the driver's knees to help protect
the knees and position you for the best interaction
with the front airbag. The Driver Inflatable Knee
Blocker fully inflates in about 50 milliseconds, this is

Airbag Light
You will want to have the airbags ready to inflate for your
protection in a collision. While the airbag system is
designed to be maintenance free, if any of the following
occurs, have an authorized dealer service the system
immediately.
²The AIRBAG light does not come on during the 6 to 8
seconds when the ignition switch is first turned on.
²The light remains on after the 6 to 8 second interval.
²The light comes on and remains on while driving.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to 5 - seconds of specific vehicle data param-
eters (see list below) in an event data recorder prior to the
moment of airbag deployment, or near-deployment, andup to a quarter second of high-speed deceleration data
during and/or after air bag deployment or near-
deployment. EDR data are ONLY recorded if an airbag
deploys, or nearly deploys, and are otherwise unavail-
able.
NOTE:
1. A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually indica-
tive of a crash, but not severe enough to warrant airbag
deployment.
2. Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete accident investigation, the electronic data may be
used by DaimlerChrysler and others to learn more about
the possible causes of crashes and associated injuries in
order to assess and improve vehicle performance. In

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. In order to ensure compass accuracy, the com-
pass variance should be properly set according to the
compass variance map zone that the vehicle is in.
NOTE:Magnetic materials should be kept away from
the Instrument Panel. This is where the compass sensor is
located.
