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 instrument
panel during airbag deployment could cause seri-
ous injury.
²Airbags need room to inflate. Sit back, comfort-
ably extending your arms to reach the steering
wheel or instrument panel.
²The side airbags also need room to inflate. Do not
lean against the door. Sit upright in the center of
the seat.
Airbag System Components
The airbag system consists of the following:
²Occupant Restraint Controller
²Airbag Warning Light
²Driver and passenger frontal airbag/inflator units
²Driver and passenger side airbag/inflator units
²Driver and Passenger Inflatable Knee Blocker
²Driver and Front Passenger Seat Belt Pretensioners
²Side impact sensors

If a Deployment Occurs
WARNING!
Deployed airbags can't protect you in another colli-
sion. Have the airbags replaced by an authorized
dealer as soon as possible.
The airbag system is designed to deploy when the impact
sensors detect a moderate-to-severe frontal collision, to
help restrain the driver and passenger, and then to
immediately deflate.
NOTE:A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system. The system may also inflate only one airbag in a
reduced severity frontal collision if the seat belt on that
40 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

side of the vehicle is not fastened. This also does not
mean something is wrong with your airbag system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
²The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and passen-
ger as the airbags deploy and unfold. The abrasions
are similar to friction rope burns or those you might
get sliding along a carpet or gymnasium floor. They
are not caused by contact with chemicals. They are not
permanent and normally heal quickly. However, if you
haven't healed significantly within a few days, or if
you have any blistering, see your doctor immediately.
²As the airbags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the nontoxic nitrogen gas used
for airbag inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you have skin oreye irritation, rinse the area with cool water. For nose
or throat irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles settle on
your clothing, follow the garment manufacturer's in-
structions for cleaning.
²It is not advisable to drive your vehicle after the
airbags have been deployed. If you are involved in
another collision, the airbags will not be in place to
protect you.
How the Side Impact Airbag System Works
²
The side impact airbags are located in the doors above
the armrest.
²The ORC determines if a side impact is severe enough
to require the airbag on the side of the vehicle sub-
jected to an impact. As with the frontal system, the
sensors are connected to the diagnostic unit and the
airbag/inflator units.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 41

²When a side impact above a predetermined threshold
occurs, the sensors signal the inflator on the impacted
side of the vehicle. A large quantity of nontoxic
nitrogen gas is generated to inflate the airbag. The
door panel opens to allow the airbag to inflate to its
full size.WARNING!
²Do not put anything on or around the airbag
covers or attempt to manually open them. You may
damage the airbags and you could be injured
because the airbags are not there to protect you.
These protective covers are designed to open only
when the airbags are inflated.
²Do not attach cup holders or any other objects on
or around the door. The inflating side airbag could
drive the objects into occupants, causing serious
injury.

How the Occupant Classification System (OCS)
System Works
The Occupant Classification System (OCS) will classify
an occupant in the front passenger seat into a size
category based on sensor readings from within the seat
cushion. Occupants should try to remain in a normally
seated position. If the occupant's weight is transferred to
another object in the vehicle (i.e. feet on the dashboard),
the OCS may not be able to properly approximate
occupant size. Furthermore, the occupant size may ap-
pear to increase or decrease due to objects hanging on the
seat, other passengers pushing on the seat, or objects
lodged underneath the seat. If there is a rapid change in
temperature or humidity, the OCS may not be able to
properly approximate occupant size. If your seat includ-
ing your trim cover and cushion needs to be serviced in
any way, take the vehicle to your authorized dealer. Only
manufacturer approved seat accessories may be used. If
there is a fault present in the system, the AIRBAGwarning light will light indicating that you should take
the vehicle to an authorized dealer. In the presence of an
occupant in the passenger seat, if both the Passenger
Airbag Disable (PAD) indicator light (located in the
center console) and AIRBAG warning light (located in
the instrument cluster) are illuminated the airbag will be
disabled. The Occupant Restraint Controller (ORC) will
not allow front airbag deployment in the event of a
collision for occupants classified into the empty or child
size categories. The PAD indicator light will illuminate
indicating that the Passenger Airbag is OFF when the
OCS has determined that the occupant size category is a
child. Also, when the seat is empty or an object that
weighs less than a predetermined threshold is placed on
the seat, the light will remain OFF. (The PAD indicator
light is an amber light located in the center console.) For
almost all sizes of properly seated adults, the passenger
frontal airbag will be enabled in the event of a collision.
For small teenagers and some small adults, depending on
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

²Do not replace the seat cover with an aftermarket seat
cover.
²Do not add a secondary seat cover other than those
approved by DaimlerChrysler/Mopart.
²At no time should any supplemental restraint system
(SRS) component or SRS related component or fas-
tener be modified or replaced with any part except
those which are approved by DaimlerChrysler/
Mopart.
How the Occupant Classification Module (OCM)
Works
The Occupant Classification Module (OCM) is located
beneath the passenger seat. The OCM classifies the
occupant into one of three size categories based on the
input from the Bladder Assembly and a Belt Tension
Sensor. The size categories include empty, child, and
adult. The OCM sends the Occupant Classification to theORC to determine if a front passenger airbag is allowed.
If a fault is present, the AIRBAG warning light is illumi-
nated.
How the Passenger Airbag Disabled (PAD)
Indicator Light Works
The Passenger Airbag Disabled (PAD) Indicator Light
indicates to the driver and passenger when the airbag is
turned OFF. In the presence of a properly seated occu-
pant, when the PAD indicator light is illuminated, the
airbag is OFF. Also, when the Occupant 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.
How the Belt Tension Sensor (BTS) Works
The Belt Tension Sensor (BTS) is located at the outboard
passenger lap belt anchor. The BTS creates a signal based
on outboard lap belt tension. This signal is sent to the
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

OCM to ensure that the resultant bladder pressure in-
crease due to applied lap belt tension does not cause a
small occupant to be classified as a larger occupant
How the Bladder Mat and Pressure Sensor Works
The Bladder Mat and Pressure Sensor are located beneath
the seat cushion foam. The pressure sensor sends a signal
to the OCM. The passenger seat assembly contains criti-
cal components that affect the passenger airbag deploy-
ment. Correctly functioning passenger seat components
are critical for the Occupant Classification System (OCS)
to properly classify the passenger and calculate the
proper airbag deployment. Do not make any modifica-
tions to the passenger seat components, assembly, or to
the seat cover.
How the Driver/Passenger Inflatable Knee
Blockers Works
When the ORC and the impact sensors detect a collision
requiring the Driver/Passenger Inflatable Knee Blockers,it signals the inflator unit. A quantity of nontoxic gas is
generated to inflate the Driver/Passenger Inflatable Knee
Blockers. The Driver/Passenger Inflatable Knee Blockers
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/Passenger Inflatable
Knee Blockers fully inflates in about 50 milliseconds, this
is only about half of the time it takes you to blink your
eyes. It then quickly deflates while helping to protect the
driver 's knees.
The Knee Impact Blockers help protect the knees and
position the occupant.
Passenger Front Airbag On/Off Switch
The ON/OFF switch is located at the right end of the
instrument panel and is accessible by opening the pas-
senger door.

Synchronizing ESP
If the power supply was interrupted (battery discon-
nected or discharged), the BAS/ESP malfunction indica-
tor light may be illuminated with the engine running. To
re-synchronize the ESP, and cancel the malfunction indi-
cator light, the steering angle sensor will need to be
recalibrated.
1. Turn the ignition switch to the ON/RUN position.
2. Rotate the steering wheel to the center position.
3. Rotate the steering wheel completely to the left, and
then rotate the steering wheel completely to the right.
4. Bring the steering wheel back to the center position.
5. The BAS/ESP malfunction indicator light will go out.
If the BAS/ESP malfunction indicator light is still illumi-
nated, the vehicle should be serviced at an authorized
dealer.
ELECTRONIC SPEED CONTROL
The electronic speed control automatically maintains the
set speed by actively regulating the throttle setting. Any
speed above approximately 20 mph (30 km/h) can be
maintained with the electronic speed control by operat-
ing the lever.

driving when reaching the service warning threshold. It
can be canceled manually by pressing the knob/button.
Once the suggested term has passed, the message plus
either the symbol for Service A or the symbol for Service
B preceded by a ± (minus symbol) blinks for approxi-
mately 30 seconds and a signal sounds every time when
turning the key to the ON/RUN position.
The FSS display can also be called up for approximately
10 seconds with the display illuminated by pressing the
knob/button twice within one second.
Following a completed A or B service your authorized
dealer sets the counter to 7,000 mi (Canada: 11 000 km).
NOTE:When disconnecting vehicle battery for one or
more days at a time, such days will not be counted. Any
such days not counted by FSS can be added by your
authorized dealer.The interval between services is determined by the type
of vehicle operation. Driving at extreme speeds, and cold
starts combined with short distance driving in which the
engine does not reach normal operating temperature,
reduce the interval between services.
However you choose to set your reference numbers, the
scheduled services as posted in the Service Booklet must
be followed to properly care for your vehicle.
23. Outside Temperature Display
The temperature display is located on the left side of the
instrument cluster, below the fuel and engine tempera-
ture gauges.
The sensor for the outside temperature indicator is
located in the front fascia area. Due to its location, the
sensor can be affected by road or engine heat during
idling or slow driving. This means that the accuracy of
UNDERSTANDING YOUR INSTRUMENT PANEL 139
4

the displayed temperature can only be verified by com-
parison to a thermometer placed next to the sensor, not
by comparison to external displays (e.g., bank signs, etc.).
Adaptation to ambient temperature takes place in steps
and depends on the prevailing driving conditions (stop-
and- go or moderate, constant driving) and amount of
temperature change.
WARNING!
The outside temperature indicator is not designed to
serve as an ice-warning device and is unsuitable for
that purpose. Indicated temperatures just above the
freezing point do not guarantee that the road surface
is free of ice.24. Airbag Light
The operational readiness of the airbag system
is verified by the airbag indicator light in the
instrument cluster when turning the key in the
ignition switch to the ACC or ON/RUN posi-
tion. If no fault is detected, the light will go out after
approximately four seconds. After the lamp goes out, the
system continues to monitor the components and cir-
cuitry of the airbag system and will indicate a malfunc-
tion by coming on again.
The light will come on and remain on for four seconds as
a bulb check when the ignition switch is first turned ON.
If the bulb is not lit during starting, have it replaced. If
the light stays on, or comes on while driving, have the
system checked by an authorized dealer.
