2007 CHRYSLER 300 LX sensor

Air Bag System Components
The airbag system consists of the following:
•Airbag Control Module (ACM)
•Side Remote Acceleration Sensors (if equipped)
•Airbag Warning Light
•Driver Airbag
•Front Passenger Airbag
•Supplemental Side Curtain Airbags above Side Win-
dows (if equipped)
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Seatbelt Reminder Light
•Knee Impact Bolsters
•Front Acceleration Sensors
•Driver and Front Passenger Seat Belt Pretensioners
How The Airbag System Works
•
TheAirbag Control Module (ACM)determines if a
frontal collision is severe enough to require the airbags
to inflate. The front airbag inflators are designed to
provide different rates of airbag inflation from direc-
tion provided by the ACM. The ACM will not detect
roll over.
•The ACM 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.
•The ACM also turns on the Airbag Warning
Light in the instrument panel for 6 to 8
seconds as a self-check when the ignition is
first turned on. After the self-check, the
Airbag Warning Light will turn off. If the ACM detects
a malfunction in any part of the system, it turns on the
Airbag Warning Light either momentarily or continu-
ously. A single chime will sound if the light comes on
again after initial start up.

•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.
The rain sensing system has protective features for the
wiper blades and arms. It will not operate under the
following conditions:
•Low Temperature Wipe Inhibit— The rain-sensing
feature will not operate when the ignition is first
switched ON, and the vehicle is stationary, and the
outside temperature is below 32° F (0° C), unless the
wiper control on the multi-function lever is moved, or
the vehicle speed becomes greater than 0 mph (0
km/h), or the outside temperature rises above freez-
ing.
•Neutral Wipe Inhibit— The rain-sensing feature will
not operate when the ignition is ON, and the trans-
mission shift lever is in the N (Neutral) position, and
the vehicle speed is less than 5 mph (8 km/h), unless
the wiper control on the multi-function lever is moved
or the shift lever is moved out of the N (Neutral)
position.
Adding Washer Fluid
The windshield washer fluid reservoir is located in the
front of the engine compartment on the passenger side of
the vehicle. Be sure to check the fluid level in the
reservoir at regular intervals. Fill the reservoir with
windshield washer solvent (not radiator antifreeze) and
operate the system for a few seconds to flush out the
residual water.

WARNING!
Speed Control can be dangerous where the system
can’t maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control. An accident could be the result. Don’t use
Speed Control in heavy traffic or on roads that are
winding, icy, snow-covered, or slippery.
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 within a distance of 328 ft (100 m).
NOTE:
•
If the sensor does not detect a vehicle directly ahead of
you, ACC will function in the same way as 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.

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.
You can change the distance setting by pulling the lever
toward 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 18 mph (26
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.

•System off
•Proximity warning
•ACC unavailable/service ACC warning
The EVIC will return to the last display selected
after 5 seconds of no ACC activity.
Display Warnings & Maintenance
ACC Unavailable Warning
The ACC Unavailable Warning will display when condi-
tions temporarily limit system performance. This most
often occurs at times of poor visibility, such as in snow,
fog, heavy rain, or when driving into direct sunlight
(sunrise or sunset). The ACC system may also become
temporarily unavailable due to obstructions, such as dirt
or ice. In these cases, the EVIC will display “ACC
UNAVAILABLE.”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.
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.

The system uses four sensors located in the rear bumper
to scan for obstacles up to 59 inches (150 cm) away from
the rear bumper fascia. The warning display located
above the rear window provides both visible and audible
warnings to indicate the range of the object.The warning display contains two sets of yellow and red
LEDs, one set to warn of obstacles behind the left rear of
the vehicle and the other set to warn of obstacles behind
the right rear of the vehicle. The driver can view the LEDs
either through the rear view mirror or by looking at the
display above the rear window.
The system dimly illuminates the two outer most yellow
LEDs when it is ON and detecting no obstacles. The
following chart shows the warning display operation
when the system is detecting an obstacle:

WARNING!
•Drivers must be careful when backing up even
when using the Rear Park Assist System. Always
check carefully behind your vehicle, look behind
you, and be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind spots be-
fore backing up. You are responsible for safety
and must continue to pay attention to your sur-
roundings. Failure to do so can result in serious
injury or death.
•Before using the Rear Park Assist System, it is
strongly recommended that the ball mount and
hitch ball assembly is disconnected from the
vehicle when the vehicle is not used for towing.
Failure to do so can result in injury or damage to
vehicles or obstacles because the hitch ball will be
much closer to the obstacle than the rear fascia
when the warning display turns the red LEDs ON.
Also, the sensors could detect the ball mount and
hitch ball assembly, depending on its size and
shape, giving a false indication that an obstacle is
behind the vehicle.
CAUTION!
•The Rear Park Assist System is only a parking aid
and it is unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will not
be detected when they are in close proximity.
•The vehicle must be driven slowly when using the
Rear Park Assist System to be able to stop in time
when the obstacle is detected. It is recommended
that the driver looks over his/her shoulder when
using the Rear Park Assist System.
NOTE:
•
Ensure that the rear bumper is free of dirt and debris
to keep the system operating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of the system.
