2012 CHRYSLER 300 SRT service

The “Clean Radar Sensor In Front Of Vehicle” message
can sometimes be displayed while driving in highly
reflective areas (i.e. tunnels with reflective tiles, or ice and
snow). The ACC system will recover after the vehicle has
left these areas. Under rare conditions, when the radar is
not tracking any vehicles or objects in its path this
warning may temporarily occur.
NOTE:If the ACC “Clean Radar Sensor In Front Of
Vehicle” warning is active Normal (Fixed Speed) Cruise
Control is still available. For additional information refer
to “Normal (Fixed Speed) Cruise Control Mode” in this
section.
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 in the center of the
vehicle behind the lower 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. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
•If the sensor is damaged due to a collision, 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.

Service ACC Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable Service Radar Sensor”, it indicates
there is an internal system fault. Although the vehicle is
still drivable under normal conditions, have the system
checked by 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.
Adding A Trailer Hitch
The weight of a trailer/hitch may affect the performance
of ACC. If there is a noticeable change in performance
following the installation of a trailer/hitch, or if the ACC
performance does not return to normal after removing
the trailer/hitch see your authorized dealer.
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.
222 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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.ACC may occasionally provide braking and/or a driver
alert that you consider unnecessary. This may be the
system’s response to signs, guardrails, and other station-
ary objects in a curve. This may also occur at the base of
steep hills. This is normal operation and your vehicle
does not require service.

Service FCW Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable Service Radar Sensor”, it indicates
there is an internal system fault. Although the vehicle is
still drivable under normal conditions, have the system
checked by an authorized dealer.
PARKSENSEPARK ASSIST — IF EQUIPPED
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear
and/or front fascia and a detected obstacle when backing
up or moving forward, e.g. during a parking maneuver.
Refer to ParkSense System Usage Precautions for limi-
tations of this system and recommendations. ParkSense
will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the shift lever is in
REVERSE or DRIVE. If ParkSense is enabled at one of
these shift lever positions, the system will remain active
until the vehicle speed is increased to approximately
7 mph (11 km/h) or above. The system will become
active again if the vehicle speed is decreased to speeds
less than approximately 6 mph (9 km/h).

Front Park Assist Audible Alerts
ParkSensewill turn off the Front Park Assist audible
alert (chime) after approximately 3 seconds when an
obstacle has been detected, the vehicle is stationary, and
brake pedal is applied.
Enabling And Disabling ParkSense 
ParkSensecan be enabled and disabled using the
Uconnect Touch™ System. The available choices are: Off,
Sound Only, or Sound and Display. Refer to “Uconnect
Touch™ Settings” in “Understanding Your Instrument
Panel” for further information.
When the ParkSense soft-key is pressed to disable the
system, the EVIC will display the “PARK ASSIST SYS-
TEM OFF” message for approximately five seconds.
Refer to “Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for further
information. When the shift lever is moved to REVERSE
or to DRIVE (at or below 7 mph [11 km/h]) and the
system is disabled, the EVIC will display the “PARK ASSIST SYSTEM OFF” message for approximately five
seconds in REVERSE or for 5 seconds when the vehicle is
in DRIVE.
Service The ParkSense
Park Assist System
When the ParkSensePark Assist System is malfunction-
ing, the instrument cluster will actuate a single chime,
once per ignition cycle. The instrument cluster will
display the “CLEAN PARK ASSIST” message when any
of the rear or front sensor(s) are blocked by snow, mud, or
ice and the vehicle is shifted into REVERSE or DRIVE.
The instrument cluster will display the “SERVICE PARK
ASSIST” message when any of the rear or front sensors
are damaged and require service. When the shift lever is
moved to REVERSE or DRIVE and the system has
detected a faulted condition, the EVIC will display the
“CLEAN PARK ASSIST”, “SERVICE PARK ASSIST” or
the “SERVICE PARK ASSIST SYSTEM” message for as
long as the vehicle is in REVERSE or DRIVE (at speeds
less than 7 mph [11 km/h]). Under this condition
ParkSense will not operate. Refer to “Electronic Vehicle

Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
If “CLEAN PARK ASSIST” appears in the Electronic
Vehicle Information Center (EVIC) make sure the outer
surface and the underside of the rear fascia/bumper
and/or front fascia/bumper is clean and clear of snow,
ice, mud, dirt or other obstruction and then cycle the
ignition. If the message continues to appear see an
authorized dealer.
If “SERVICE PARK ASSISTor “SERVICE PARK ASSIST
SYSTEM” appears in the EVIC, see an authorized dealer.
Cleaning The ParkSense System
Clean the ParkSense sensors with water, car wash soap
and a soft cloth. Do not use rough or hard cloths. Do not
scratch or poke the sensors. Otherwise, you could dam-
age the sensors.
ParkSense System Usage Precautions
NOTE:
•Ensure that the front and rear bumper are free of snow,
ice, mud, dirt and debris to keep the ParkSense 
system operating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
•When you turn ParkSense off, the EVIC will display
“PARK ASSIST SYSTEM OFF.” Furthermore, once you
turn ParkSense off, it remains off until you turn it on
again, even if you cycle the ignition key.
•When you move the shift lever to the REVERSE or
DRIVE position and ParkSense is turned off, the
EVIC will display “PARK ASSIST SYSTEM OFF”
message for approximately five seconds in REVERSE
or for 5 seconds when the vehicle is in DRIVE.
238 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•Clean the ParkSensesensors regularly, taking care
not to scratch or damage them. The sensors must not
be covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle is
behind or in front of the fascia/bumper.
•Objects such as bicycle carriers, trailer hitches, etc.,
must not be placed within 12 in (30 cm) from the rear
fascia/bumper while driving the vehicle. Failure to do
so can result in the system misinterpreting a close
object as a sensor problem, causing the “SERVICE
PARK ASSIST” message to be displayed in the EVIC.
CAUTION!
•ParkSense is only a parking aid and it is unable
to recognize every obstacle, including small ob-
stacles. Parking curbs might be temporarily de-
tected or not detected at all. Obstacles located
above or below the sensors will not be detected
when they are in close proximity.
•The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time
when an obstacle is detected. When backing up, it
is recommended that the driver looks over his/her
shoulder when using ParkSense.

6. Odometer Display / Electronic Vehicle Information
Center (EVIC) Display
Odometer Display
The odometer display shows the total distance the ve-
hicle has been driven.
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. If your
odometer needs to be repaired or serviced, the repair
technician should leave the odometer reading the same
as it was before the repair or service. If s/he cannot do so,
then the odometer must be set at zero, and a sticker must
be placed in the door jamb stating what the mileage was
before the repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/
service, so that you can be sure that it is properly reset, or
that the door jamb sticker is accurate if the odometer
must be reset at zero.Electronic Vehicle Information Center (EVIC) Display
The Electronic Vehicle Information Center (EVIC) fea-
tures a driver-interactive display that is located in the
instrument cluster. For further information, refer to
“Electronic Vehicle Information Center (EVIC)”.
The Shift Lever Indicator is self-contained within the
EVIC display. It displays the gear position of the auto-
matic transmission.
NOTE:
•You must apply the brakes before shifting from PARK.
•The highest available transmission gear is displayed in
the lower right corner of the Electronic Vehicle Infor-
mation Center (EVIC) whenever the Electronic Range
Select (ERS) feature is active. Use the +/- selector on
the shift lever to activate ERS. Refer to “Automatic
Transmission” in “Starting And Operating” for further
information.
