2008 CHRYSLER 300 SRT 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.

To Vary the Speed Setting
While ACC is set, you can increase the set speed by lifting
and holding the lever in RESUME ACCEL. If the lever is
continually held, the set speed will continue to increase
in 5 mph (Canada 10 km/h) increments until the lever is
released. The increase in set speed is reflected in the EVIC
display.
Tapping the lever up once will result in a 1 mph (Canada
1 km/h) increase in set speed. Each subsequent tap of the
lever results in an increase of 1 mph (Canada 1 km/h).
While ACC is set, the set speed can be decreased by
pushing and holding the lever down in SET DECEL. If
the lever is continually held, the set speed will continue
to decrease in 5 mph (Canada 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
(Canada 1 km/h) decrease in set speed. Each subsequent
tap of the lever results in a decrease of 1 mph (Canada 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 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 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.
Adaptive Cruise Control (ACC) Menu
The EVIC displays the current ACC system settings. The
EVIC is located in the upper part of the instrument
cluster between the speedometer and the tachometer. The
information it displays depends on ACC system status.

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.
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.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
dramatic hills. This is normal operation and your vehicle
does not require service.
Using ACC on Hills
When driving on hills, ACC may not detect a vehicle in
your lane. Depending on the speed, vehicle load, traffic
conditions, and the steepness of the hills, ACC perfor-
mance may be limited.

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 will not until it may be too late 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 attentive and ready to apply the
brakes if necessary.
170 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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.
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.

REAR PARK ASSIST SYSTEM
The Rear Park Assist System is a driver aid that senses for
obstacles behind the vehicle. Refer to the Warnings,
Cautions, and Notes in this section for system limitations
and usage recommendations.
The Rear Park Assist System is active when the driver
shifts the transmission into the REVERSE position, and
the parking brake is not applied, and the vehicle speed is
less than 10 mph (16 km/h).The system can be turned on or off through the Electronic
Vehicle Information Center (EVIC) when the vehicle is in
PARK. Refer to “Personal Settings (Customer Program-
mable Features)” under “Electronic Vehicle Information
Center (EVIC)” in Section 4.
The system uses four sensors located in the rear bumper
to scan for obstacles up to 59 in (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.
