Seat Belt Pretensioners
The seat belts for both front seating positions are
equipped with pretensioning devices that are designed to
remove any slack from the seat belts in the event of a
collision. These devices improve the performance of the
seat belt system by assuring that the belt is tight about the
occupant in a collision. Pretensioners work for all size
occupants, including those in child restraints.
NOTE:These devices are not a substitute for proper
seat belt placement by the occupant. The seat belt still
must be worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Re-
straint Controller (ORC) (see Airbag Section). Like the
front airbags, the pretensioners are single use items. After
a collision that is severe enough to deploy the airbags and
pretensioners, both must be replaced.
Enhanced Driver Seat Belt Reminder System
(BeltAlert)
If the driver’s seat belt has not been buckled within 60
seconds of starting the vehicle and if the vehicle speed is
greater than 5 mph (8 km/h), the Enhanced Warning
System (BeltAlert) will alert the driver to buckle their seatbelt. The driver should also instruct all other occupants to
buckle their seat belts. Once the warning is triggered, the
Enhanced Warning System (BeltAlert) will continue to
chime and flash the Seat Belt Warning Light for 96
seconds or until the driver’s seat belt is buckled. The
Enhanced Warning System (BeltAlert) will be reactivated
if the driver’s seat belt is unbuckled for more than 10
seconds and the vehicle speed is greater than 5 mph (8
km/h).
The Enhanced Warning System (BeltAlert) can be en-
abled or disabled by your authorized dealer or by
following these steps:
NOTE:The following steps must occur within the first
60 seconds of the ignition switch being turned to the ON
or START position. DaimlerChrysler does not recom-
mend deactivating the Enhanced Warning System
(BeltAlert).
1. Turn the ignition switch to the LOCK position and
buckle the driver’s seat belt.
2. Turn the ignition switch to the ON position and wait
for the Seat Belt Warning Light to turn off.

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.
•Also, the ORC turns on the airbag warning
light and PAD indicator light in the instru-
ment 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. ThePAD indicator light will function normally (Refer to
Passenger 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 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.
•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 in the unlikely event that a rear-facing infant
seat is in the front passenger seat.
40 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
NOTE:Children 12 years and under should always ride
buckled up in a rear seat in an appropriate child restraint.
•ThePassenger Air Bag 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 air bag is turned off. The PAD indica-
tor lamp illuminates the front passenger air bag icon
and the wordsPASS AIR BAG OFFto show that the
passenger air bag will not inflate during a collision
requiring air bags. 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 PAD indicator lamp is not illuminated.
The PAD indicator light should not be illuminated
when teenagers, most children in a forward-facing
child restraint or booster seats, most children that can
properly wear the vehicle’s seat belt, and when an
adult passenger is properly seated in the front passen-
ger seat. In this case, the air bag is ready to be inflated
if a collision requiring an air bag occurs.

For almost all properly installed rear facing child
restraints, the PAD indicator light will be illuminated
indicating that the front passenger air bag is turned off
and will not inflate. If the PAD indicator light is not
illuminated,DO NOTassume the air bag is turned off
and move the child restraint to the rear seat. A
deploying passenger air bag can cause death or seri-
ous injury to a child in a rear facing infant seat.
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 appro-
priate child restraint (see section on child restraints).

* Since the system senses weight, some small objects
will turn the PAD Indicator Light on.
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 because
42 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
this 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 PADIndicator 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 theoutside edge of the headliner out of the way and
covers the window. The airbag inflates in about 30
milliseconds (about one quarter of the time it takes to
blink your eyes) with enough force to injure you if you
are not belted and seated properly, or if items are
positioned in the area where the side curtain airbag
inflates. This especially applies to children. The side
curtain airbag is only about 3-1/2 inches (9 cm) thick
when it is inflated.
•TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System
(OCS) to properly classify the front passenger and calcu-
late the proper airbag deployment. Do not make any
modifications to the front passenger seat components,
assembly, or to the seat cover.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
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
associated with universities, and with hospital and insur-
ance 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
(usually the vehicle owner or lessee) before accessing the
electronic data stored, unless ordered to download data
by a court with legal jurisdiction (i.e., pursuant to a
warrant). A copy of the data will be provided to the
custodial entity upon request. General data that does not
identify particular vehicles or crashes may be released for
incorporation in aggregate crash databases, such as those
maintained by the US government and various states.
Data of a potentially sensitive nature, such as would
identify a particular driver, vehicle, or crash, will betreated confidentially. Confidential data will not be dis-
closed by DaimlerChrysler to any third party except
when:
1. Used for research purposes, such as to match data
with a particular crash record in an aggregate database,
provided confidentiality of personal data is thereafter
preserved
2. Used in defense of litigation involving a
DaimlerChrysler product
3. Requested by police under a legal warrant
4. Otherwise required by law
Data Parameters that May Be Recorded:
•Diagnostic trouble code(s) and warning lamp status
for electronically-controlled safety systems, including
the airbag system
•Airbag disable lamp status (if equipped)
•Timeof airbag deployment (in terms of ignition
cycles and vehicle mileage)
•Airbag deployment level (if applicable)

•The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children who weigh up
to about 20 lbs (9 kg). “Convertible” child seats can be
used either rearward-facing or forward-facing in the
vehicle. Convertible child seats often have a higher
weight limit in the rearward-facing direction than
infant carriers do, so they can be used rearward-facing
by children who weigh more than 20 lbs (9 kg) but are
less than one year old. Both types of child restraints are
held in the vehicle by the lap/shoulder belt or the
LATCH child restraint anchorage system. (See the
LATCH — Child Seat Anchorage System section.)
•Rearward-facing child seats mustNEVERbe used in
the front seat of a vehicle with the front passenger
airbag unless the airbag is turned off. An airbag
deployment could cause severe injury or death to
infants in this position.
WARNING!
•Improper installation can lead to failure of an
infant or child restraint. It could come loose in a
collision. The child could be badly injured or
killed. Follow the manufacturer’s directions ex-
actly when installing an infant or child restraint.
•A rearward facing child restraint should only be
used in a rear seat. A rearward facing child re-
straint in the front seat may be struck by a
deploying passenger airbag which may cause se-
vere or fatal injury to the infant.
Here are some tips on getting the most out of your child
restraint:
•Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
Standards. We also recommend that you make sure
that you can install the child restraint in the vehicle
where you will use it before you buy it.
