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 airbag control
module (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 Seat Belt Reminder System (BeltAlert)
If the driver’s or front passenger’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 or front passenger to buckle their seat belt. Thedriver 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 or front passenger’s seat belt
is buckled. The Enhanced Warning System (BeltAlert)
will be reactivated if the driver’s or front passenger’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.

If a child from 1 to 12 years old must ride in the front
passenger seat because the vehicle is crowded, move the
seat as far back as possible, and use the proper child
restraint. See the section on “Child Restraint”.
2. You should read the instructions provided with your
child restraint to make sure that you are using it properly.
3. All occupants should use their seat belts properly.
4. The driver and front passenger seats should be moved
back as far as practical to allow the airbags time to inflate.
5. If your vehicle has left and right side curtain airbags,
do not lean against the door, airbags will inflate forcefully
into the space between you and the door.
6. If the airbag system in this vehicle needs to be
modified to accommodate a disabled person, contact the
Customer Center. Phone numbers are provided in theIf
You Need Customer Assistancesection in this manual.WARNING!
•Relying 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.
•Being too close to the steering wheel or instru-
ment panel during 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.
•If the vehicle has left and right side curtain
airbags, they also need room to inflate. Do not
lean against the door or window. Sit upright in the
center of the seat.
Airbag System Components

consists of the following:
•Airbag Control Module
•AIRBAGReadiness Light
•Left and Right Side Curtain Airbags Above Side
Windows
•Left and Right Side Impact Sensors
•Interconnection Wiring
How The Airbag System Works
•
The airbag control module determines if a frontal
collision is severe enough to require the airbags to
inflate. The control module receives the level of colli-
sion severity, determines the proper level of airbag to
be deployed. The frontal airbag inflators are designed
to provide three different rates of airbag inflation.
•The airbag control module will not detect a rollover.
•The airbag control module 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 instrument 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.
•The airbag control module also turns on the
AIRBAGlight, and thePassenger Airbag

ment panel for 6 to 8 seconds when the
ignition is first turned on, then turns the light off. If it

Occupant Classification System
•
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.
NOTE:Children 12 years and under should always ride
buckled up in a rear seat in an appropriate child restraint.
•ThePassenger 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 wordsPASS AIR BAG OFF
to show that the passenger airbag will not inflate
during a collision requiring airbags.This light should not be illuminated when an adult
passenger is properly seated in the front passenger
seat. In this case, the airbag is ready to be inflated if a
collision requiring an airbag occurs. The PAD Indica-
tor Light is also turned off when the seat is empty. The
only time that the PAD Indicator Light is turned on is
when a small weight is in the front passenger seat. The
system is required to turn on the PAD Indicator Light
when the weight in the front passenger seat is close to
a rear-facing infant seat. Relatively light objects like
brief cases and grocery bags will also turn on the PAD
Indicator Light. The PAD Indicator Light will be off
when teenagers, most children and most children in
forward-facing seats are in the front passenger seat.
The system is only required to turn the PAD Indicator
Light on in the unlikely event that a rear-facing infant
seat is installed in front passenger seat.

* 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 anadult. An adult occupant needs to sit in a normal position
(with their feet on or near the floor) in order to be
properly classified.
Drivers and adult passengers should verify that the PAD
Indicator Light is not illuminated when they are 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.
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.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If the 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.
•ThePassenger Airbag Disabled (PAD) Indicator
Lightindicates to the driver and passenger when the
airbag is turned OFF. In the presence of a properly
seated occupant, when the PAD indicator light isilluminated, the airbag is OFF. Also, when the Occu-
pant 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.
•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.
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.

Child Restraint
Everyone in your vehicle needs to be buckled up all the
time, babies and children, too. Every state in the United
States and all Canadian provinces require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it.
Children 12 years and under should ride properly buck-
led up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front.
WARNING!
In a collision, an unrestrained child, even a tiny
baby, can become a missile inside the vehicle. The
force required to hold even an infant on your lap
could become so great that you could not hold the
child, no matter how strong you are. The child and
others could be badly injured. Any child riding in
your vehicle should be in a proper restraint for the
child’s size.
