2010 CHRYSLER 300 brake

•The system will not be controlling the distance be-
tween your vehicle and the vehicle ahead. The vehicle
speed will only be determined by the position of the
accelerator pedal.
To Cancel
The system will disable ACC without erasing the
memory if:
•You softly tap the brake pedal.
•You depress the brake pedal.
•You pull the speed control lever toward you to CAN-
CEL.
•The Electronic Stability Program/Traction Control
System (ESP/TCS) activates.3

While ACC is set, the set speed can be decreased by
pushing and holding the lever down (SET/DECEL). If
the lever is continually held, the set speed will continue
to decrease in 5 mph (10 km/h) increments until the lever
is released. The decrease in set speed is reflected in the
EVIC display.
Tapping the lever down once will result ina1mph
(1 km/h) decrease in set speed. Each subsequent tap of
the lever results in a decrease of 1 mph (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 can only apply a maximum of 25% of
the vehicle’s braking capability and will not bring the
vehicle to a complete stop.
•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.

•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
“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.3

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 hitch, such as reduced
detection range, please see your authorized dealer for
service.
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.

Lane Changing
ACC will not detect a vehicle until it is completely in the
lane in which you are traveling. In the illustration shown,
ACC has not yet detected the vehicle changing lanes and
it may detect the vehicle until it’s too late for the ACC
system to take action. ACC will not detect a vehicle until
it is completely in the lane. There will not be sufficient
distance to the lane-changing vehicle. Always be atten-
tive and ready to apply the brakes if necessary.
Narrow Vehicles
Some narrow vehicles traveling near the outer edges of
the lane or edging into the lane are not detected until they
have moved fully into the lane. There will not be suffi-
cient distance to the vehicle ahead.
180 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Stationary Objects and Vehicles
ACC does not react to stationary objects and stationary
vehicles. For example, ACC will not react in situations
where the vehicle you are following exits your lane and
the vehicle ahead is stopped in your lane. Always be
attentive and ready to apply the brakes if necessary.

To Vary the Speed Setting
There are two ways to change the set speed:
•Use the accelerator pedal to adjust the vehicle to the
desired speed and push the lever down (SET/DECEL).
•Tap the stalk up (ACCEL) or down (DECEL) to
increase or decrease the set speed in 1 mph (1 km/h)
increments respectively. Hold the lever up (ACCEL) or
down (DECEL) for 5 mph (10 km/h) increments.
To Cancel
The system will disable Normal cruise control without
erasing the memory if:
•You softly tap or depress the brake pedal.
•You pull the speed control lever toward you (CAN-
CEL).
•The Electronic Stability Program/Traction Control
System (ESP/TCS) activates.
To Resume
Push the lever up and release (RESUME/ACCEL) 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/MODE button.
•You turn off the ignition.
•You switch off ESP.
If the cruise control system is turned off and reactivated,
the system will return to the Vehicle-to-vehicle (adaptive)
distance control mode.

PARKSENSEREAR PARK ASSIST
The ParkSense Rear Park Assist system is a driver aid
that senses for obstacles behind the vehicle. Refer to
ParkSense System Usage Precautions for limitations of
this system and recommendations.
ParkSense is active when the driver shifts the transmis-
sion into the REVERSE position, and the parking brake is
not applied, and the vehicle speed is less than 10 mph
(16 km/h).
ParkSense can be turned on or off through the Electronic
Vehicle Information Center (EVIC) when the vehicle is in
PARK. Refer to “Electronic Vehicle Information Center
(EVIC)/Personal Settings (Customer-Programmable Fea-
tures)” in “Understanding Your Instrument Panel” for
further information. ParkSense
uses four sensors located in the rear bumper
to scan for obstacles up to 79 in (200 cm) away from the
rear bumper fascia. The ParkSense Warning Display
located above the rear window provides both visible and
audible warnings to indicate the range of the object.
