During a moderate-to-severe rear impact the ORC
may deploy the seat belt pretensioners alone.
Also, the ORC turns on the AIRBAG warn-
ing 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 toPassenger Airbag Disable (PAD)
Indicator Lightin this section). If the ORC detects a
malfunction in any part of the system, it turns on the
AIRBAG warning light either momentarily or continu-
ously. 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.
•TheOccupant 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.
•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 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.
•ThePassenger Airbag Disabled (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 Indicator lamp illuminates the wordsPASS AIR
BAG OFFto 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 will not inflate even though the Passenger Airbag
Disable (PAD) indicator lamp is not illuminated.The PAD indictor light should not be illuminated
when an adult passenger is properly seated in the
front passenger seat. In this case, the air bag is ready to
be inflated if a collision requiring an airbag occurs.
For all other occupants, the PAD indicator light will be
illuminated indicating that the front passenger airbag
is turned off and will not inflate.
NOTE:Even though this vehicle is equipped with an
occupant classification system, children 12 years and
under should always ride buckled up in a rear seat in an
appropriate child restraint (see section on child re-
straints).
WARNING!
Never place a rear facing infant seat in front of an
airbag. A deploying passenger airbag can cause
death or serious injury to a child in a rear facing
infant seat.

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 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.

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.
•The AIRBAG light does not come on during the 6 to 8
seconds when the ignition switch is first turned on.
•The light remains on after the 6 to 8 second interval.
•The 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, and
up 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
addition to crash investigations initiated by
DaimlerChrysler, such investigations may be requested
by customers, insurance carriers, government officials,
and professional crash researchers, such as those associ-
ated with universities, and with hospital and insurance
organizations.
In the event that an investigation is undertaken by
DaimlerChrysler (regardless of initiative), the company
or its designated representative will first obtain permis-
sion of the appropriate custodial entity for the vehicle
