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.

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
Disable (PAD) Indicator Lightin the instru-
ment panel for 6 to 8 seconds when the
ignition is first turned on, then turns the light off. If it
detects a malfunction in any part of the system, it turns
on the light either momentarily or continuously.
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.
•When the airbag control module detects a collision
requiring the airbags, it signals the inflator units. A
large quantity of nontoxic gas is generated to inflate
the airbags. Three levels of airbag inflation rates are
possible. These rates are determined by the airbag
control module based on collision severity. The airbag
covers separate and fold out of the way as the airbags
40 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•It 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.
WARNING!
Deployed airbags can’t protect you in another colli-
sion. Have the airbags replaced by an authorized
dealer as soon as possible.
Enhanced Accident Response Feature
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately 5 seconds after the vehicle has stopped
moving, the interior lights will illuminate to aid visibility.
NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
Side Airbag System
The airbag control module determines if a side collision is
severe enough to require the airbag to inflate. The control
module receives the level of collision severity from the
side impact sensors. The airbag control module will not
detect rollover or rear impacts.
The side impact SRS Airbags are designed to activate
only in certain side collisions. When the airbag control
module detects a collision requiring the side curtain
airbags 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 airbags. The inflating side curtain
airbag pushes the outside edge of the headliner out of the
way and inflates (in about the same 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
1⁄2inches (83⁄4cm) thick when it is inflated.

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.
NOTE:Children 12 years and under should always ride
buckled up in a rear seat in an appropriate child restraint.

* 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.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
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, boththe 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 is
illuminated, 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.
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The ESP warning light, located in the instru-
ment cluster, starts to flash as soon as the ESP
system sensor’s information varies from the
driver’s intended path. The ESP warning light
also flashes when traction control is activated. If the ESP
warning light begins to flash during acceleration, ease up
on the accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the prevailing
road conditions. When the ESP warning light is illumi-
nated continuously, the ESP is switched off. To return to
the enhanced vehicle stability offered by ESP, press the
ESP switch (the ESP warning light in the instrument
cluster goes out). Avoid spinning one drive wheel. This
may cause serious damage to the drive train and is not
covered by the DaimlerChrysler warranty.
To improve the vehicle’s traction when driving with
snow chains, or starting off in deep snow, sand or gravel,
switch off the ESP system by pressing the ESP switch.With the ESP system switched off, the engine torque
reduction feature is cancelled. Therefore, the enhanced
vehicle stability offered by ESP is unavailable. ESP al-
ways operates under braking, even with the switch in the
OFF position. When the ESP system is disabled (if one
drive wheel loses traction and begins to spin) the brake is
applied by the ESP system to control wheel slip. This
wheel slip control is active at vehicle speeds between
approximately 24 mph (40 km/h) and 50 mph (80 km/h).

In the event of an EBD failure, the Brake Warning Light
will turn on along with the ABS Light. Immediate repair
to the ABS system is required.
The operation of the Brake Warning Light can be checked
by turning the ignition switch from the OFF position to
the ON position. The light should illuminate for approxi-
mately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is detected.
If the light does not illuminate, have the light inspected
by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
20. Vehicle Theft Alarm (VTA) Indicator Light
The VTA indicator Light flashes rapidly when the VTA is
arming, and slowly when the VTA is armed.
21. Tire Pressure Monitor Warning Light—If
Equipped
This light will turn on continuously when
there is a Low tire pressure condition. The
light will also turn on if a problem exist with
any tire sensor. When a system fault is
detected, the indicator lamp will flash repetitively for
ten seconds. The flash cycle will repeat every ten
minutes or until the fault condition is removed and
reset. The light will remain on or flashing until the tire
pressure is properly set or the problem with the sensor
is corrected.
This light will turn on momentarily as a bulb check when
the engine is started.
When the tire pressure monitoring system warning light
is lit, one or more of your tires is significantly underin-
flated. You should stop and check your tires as soon as
possible, and inflate them to the proper pressure as
indicated on the Tire and Loading Information Placard.
Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla-
tion also reduces fuel efficiency and tire tread life, and
