Air Bag System Components
The airbag system consists of the following:
•Occupant Restraint Controller (ORC)
•Side Remote Acceleration Sensors (if equipped)
•Airbag Warning Light
•Driver Airbag
•Front Passenger Airbag
•Supplemental Side Curtain Airbags above Side Win-
dows (if equipped)
•Supplemental Front-Seat-Mounted Side Airbags (if
equipped)
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Seat Belt Reminder Light
•Knee Impact Bolsters
•Front Acceleration Sensors
•Driver and Front Passenger Seat Belt Pretensioners
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 will not
detect roll over.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to 5 seconds of specific vehicle data parameters
(see the following list) 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 airbag deployment. EDR data
are ONLY recorded if an airbag deploys, or nearly
deploys, and are otherwise unavailable.
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 beused by DaimlerChrysler Corporation and others to learn
more about the possible causes of crashes and associated
injuries in order to assess and improve vehicle perfor-
mance. In addition to crash investigations initiated by
DaimlerChrysler Corporation, such investigations may
be requested by customers, insurance carriers, govern-
ment officials, and professional crash researchers, such as
those associated with universities, and with hospital and
insurance organizations.
In the event that an investigation is undertaken by
DaimlerChrysler Corporation (regardless of initiative),
the company or its designated representative will first
obtain permission 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

The Headlights On with Wipers feature can be turned on
or off through the Electronic Vehicle Information Center
(EVIC) — if equipped. For details, refer to ”Headlights
On with Wipers,” under “Personal Settings (Customer
Programmable Features),” under “Electronic Vehicle In-
formation Center” in Section 4 of this manual.
Rain Sensing Wipers — If Equipped
This feature senses moisture on the windshield and
automatically activates the wipers for the driver. This
feature is especially useful for road splash or over spray
from the windshield washers of the vehicle ahead. Rotate
the end of the multi-function lever to one of the six
intermittent wiper settings to activate this feature.
The sensitivity of the system is adjustable from the
multi-function lever. Wiper delay position 1 is the least
sensitive and wiper delay position 6 is the most sensitive.
Choose setting 3 or 4 for normal rain conditions. Choose
setting 2 or 1 if you desire less wiper sensitivity. Choosesetting 5 or 6 if you desire more sensitivity. Place the lever
in the OFF position when not using the system.
NOTE:
•The rain-sensing feature will not operate when the
wiper speed is in the LOW or HIGH position.
•The rain-sensing feature may not function properly
when ice or dried salt water is present on the wind-
shield.
•Use of Rain-Xor products containing wax or silicone
may reduce rain sensor performance.
•The Rain Sense feature can be turned on and off
through the Electronic Vehicle Information Center
(EVIC) — if equipped. For details, refer to “Personal
Settings (Customer Programmable Features)” under
“Electronic Vehicle Information Center (EVIC)” in
Section 4 of this manual.

ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by cruise control while traveling
on highways and major roadways. However, it is not a
safety system and not designed to prevent collisions.
ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constant
need to reset your cruise control. ACC utilizes an infrared
sensor designed to detect a vehicle directly ahead in your
path.NOTE:
•If the sensor does not detect a vehicle directly ahead of
you, ACC will function in the same way as a standard
cruise control system. For additional information, refer
to “Electronic Speed Control” in this section.
•If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration automatically so
that your vehicle maintains a preset following dis-
tance.

Tapping the lever down once will result ina1mph
(Canada 1 km/h) decrease in set speed. Each subsequent
tap of the lever results in a decrease of 1 mph (Canada
1 km/h).
NOTE:
•When you use the lever to decelerate, if the engine’s
braking power does not slow the vehicle sufficiently to
reach the set speed, the brake system will automati-
cally slow the vehicle.
•The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting
may occur while climbing uphill or descending down-
hill. This is normal operation and necessary to main-
tain set speed.
Setting the Following Distance in ACC
The specified following distance for ACC can be set by
varying the distance setting between long, medium, and
short. Using this distance setting and the vehicle speed,
ACC calculates and sets the distance to the vehicle ahead.
This distance setting displays in the EVIC.
1 — Sensor Bars. Default Distance Setting is Three Bars = Long.UNDERSTANDING THE FEATURES OF YOUR VEHICLE 159

You can change the distance setting by pushing the lever
away from you and release (“DISTANCE”). Each time
this is done, the distance setting toggles between long,
medium, and short.
If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the EVIC displays the “Sensed Vehicle Indi-
cator” icon, and the system adjusts vehicle speed auto-
matically to maintain the distance setting, regardless of
the set speed.The vehicle will then maintain the set distance until:
•The vehicle ahead accelerates to a speed above the set
speed.
•The vehicle ahead moves out of your lane or view of
the sensor.
•The vehicle ahead slows to a speed below 15 mph (24
km/h) and the system automatically disables itself.
•The distance setting is changed.
•The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE:The brake lights will illuminate whenever the
ACC system applies the brakes.

If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located behind the grille,
slightly offset from the center of the grille.
To keep the ACC System operating properly, it is impor-
tant to note the following maintenance items:•Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
•Do not remove any screws from the sensor or the
sensor mount. Doing so could cause an ACC system
malfunction or failure and require a sensor re-
alignment.
•If the sensor is damaged due to an accident, see your
authorized dealer for service.
•Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or
malfunction.
When the condition that deactivated the system is no
longer present, the system will return to the “ACC Off”
state and will resume function by simply reactivating it.

NOTE:Installing a vehicle front-end protector or an
aftermarket grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit ACC
operation.
ACC Unavailable Warning
If the system turns off, and the EVIC displaysACC
UNAVAILABLE,there may be a temporary malfunction
that limits ACC functionality. In this case, ACC will be
temporarily unavailable. If this occurs, try activating
ACC again later, following a key cycle. If the problem
persists, see your authorized dealer.
Service ACC Warning
If the system turns off, and the EVIC displays “SERVICE
ACC,” it indicates there is an internal system fault that
requires service from an authorized dealer.
