2008 CHRYSLER 300 Owners Manual

A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to
maintain the set distance. If this occurs, a visual alert
(“ATTENTION”) will flash in the EVIC and a chime will
sound while ACC continues to apply its maximum
braking capacity. When this occurs, you should immedi-
ately apply the brakes as needed to maintain a safe
distance from the vehicle ahead.

Display Warnings & Maintenance
ACC Blinded Warning
The ACC Blinded Warning will display when conditions
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 tempo-
rarily blinded due to obstructions, such as dirt or ice. In
these cases, the EVIC will display “ACC Blinded.”

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.

Precautions While Driving with ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpect-
edly. The driver needs to stay alert and may need to
intervene.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel. There will not be
sufficient distance to the vehicle ahead. The offset vehicle
may move in and out of the line of travel, which can
cause your vehicle to brake or accelerate unexpectedly.
Turns and Bends
In turns or bends, ACC may detect a vehicle ahead too
late or too early. This may cause your vehicle to brake late
or unexpectedly. Give extra attention in curves and be
ready to apply the brakes if necessary. Be sure to select an
appropriate speed while driving in curves.
