2012 CHRYSLER 300 SRT brake sensor

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 Indicator”
icon, and the system adjusts vehicle speed automatically 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 disengages
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.
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
“BRAKE” will flash in the EVIC and a chime will sound
while ACC continues to apply its maximum braking
capacity. When this occurs, you should immediately
apply the brakes as needed to maintain a safe distance
from the vehicle ahead.

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.

To Cancel
The system will disable normal Cruise Control without
erasing the memory if:
•You softly tap or depress the brake pedal.
•You press the CANCEL button.
•The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.
To Resume
Press the RES+button and then remove your foot from
the accelerator pedal. The EVIC will display the last set
speed.
To Turn Off
The system will turn off and erase the set speed in
memory if:
•You push and release the ON/OFF button.
•You turn off the ignition.
•You switch off ESC. If the Cruise Control system is turned off and reactivated,
the system will return to the last driver setting (ACC or
Normal Cruise Control).
Forward Collision Warning — If Equipped
Forward Collision Warning (FCW) warns the driver of a
potential collision with the vehicle in front of you and
prompts the driver to take action in order to avoid the
collision.
FCW monitors the information from the forward looking
sensor as well as the Electronic Brake Controller (EBC),
wheel speed sensors, i.e., to calculate a probable rear-end
collision. When the system determines that a rear-end
collision is probable a warning message (both audible
and visual) will be displayed on the EVIC. When the
system determines a collision with the vehicle in front of
you is no longer probable, the warning message will be
deactivated.

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

WARNING!
The BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
BAS cannot prevent collisions, including those result-
ing from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. The capabilities of
a BAS-equipped vehicle must never be exploited in a
reckless or dangerous manner that could jeopardize
the user’s safety or the safety of others.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for oversteering and understeering the vehicle
by applying the brake of the appropriate wheel. Enginepower may also be reduced to assist in counteracting the
condition of oversteer or understeer and help the vehicle
maintain the desired path.
The ESC uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESC applies the
brake of the appropriate wheel to assist in counteracting
the condition of oversteer or understeer.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
