2009 CHRYSLER 300 C Owners Manual

WARNING! (Continued)
•Cannot take street, traffic, and weather conditions
into account, and may be limited upon adverse
sight distance conditions.
•Does not predict the lane curvature or the move-
ment of preceding vehicles and will not compen-
sate for such changes.
•Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.
•May not detect a vehicle ahead when strong light
(for example, sunrise or sunset) is directly shining
on the front of the vehicle.
•Can only apply a maximum of 25% of the vehicle’s
braking capability, and will not bring the vehicle
to a complete stop.
WARNING!
You should switch off the ACC system:
•When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situations
(i.e., in highway construction zones).
•When entering a turn lane or highway off ramp;
when driving on roads that are winding, icy,
snow-covered, slippery, or have steep uphill or
downhill slopes; and when towing a trailer.
•When circumstances do not allow safe driving at a
constant speed.
Failure to follow these warnings can result in an
accident or serious personal injury.

The Cruise Control system has two control modes.
•Adaptive cruise control mode for maintaining an
appropriate distance between vehicles.
•Normal (fixed speed) cruise control mode for cruising
at a constant preset speed. For additional information,
refer to “Normal (Fixed Speed) Cruise Control Mode”
in this section. Note: The system will not react to
preceding vehicles. Always be aware of the mode
selected.
You can change the mode by using the control lever. The
two control modes function differently. Always confirm
which mode is selected.
Adaptive Cruise Control (ACC) Operation
The speed control lever (located on the right side of the
steering wheel) operates the ACC system.

Activating Adaptive Cruise Control (ACC)
You can only activate ACC if the vehicle speed is above
25 mph (40 km/h).
When the system is turned on and in the READY state,
the Electronic Vehicle Information Center (EVIC) dis-
plays “ACC READY.”
When the system is OFF, the EVIC displays “CRUISE
OFF.”
NOTE:You cannot enable ACC under the following
conditions:
•When you apply the brakes.
•When the parking brake is set.
•When the automatic transmission is in PARK, RE-
VERSE, or NEUTRAL.
•When the Electronic Stability Program (ESP) is
switched off.
•When pushing the RESUME/ACCEL switch without a
previously set speed in memory.
To Activate
Push and release the ON/OFF/MODE button located on
the end of the speed control lever. The ACC menu in the
EVIC displays “ACC READY.”

To turn the system OFF, push and release the ON/OFF/
MODE button again. At this time, the system will turn off
and the EVIC will display “CRUISE OFF.”
WARNING!
Leaving the Adaptive Cruise Control (ACC) system
on when not in use is dangerous. You could acciden-
tally set the system or cause it to go faster than you
want. You could lose control and have an accident.
Always leave the system off when you are not using
it.
To Set a Desired Acc Speed
When the vehicle reaches the speed desired, push the
lever downward (SET/DECEL) and release. The EVIC
will display the set speed.Remove your foot from the accelerator pedal. If you do
not, the vehicle may continue to accelerate beyond the set
speed. If this occurs:
•The message “DRIVER OVERRIDE” will display in
the EVIC.
162 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•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 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.
To Resume Speed
Push the lever upward (RESUME/ACCEL) and release.
Then remove your foot from the accelerator pedal. The
EVIC will display the last set speed.
WARNING!
The Resume function should only be used if traffic
and road conditions permit. Resuming a set speed
that is too high or too low for prevailing traffic and
road conditions could cause the vehicle to accelerate
or decelerate too sharply for safe operation. This
could cause an accident and/or serious injury.
To Vary the Speed Setting
While ACC is set, you can increase the set speed by lifting
and holding the lever up (RESUME/ACCEL). If the lever
is continually held, the set speed will continue to increase
in 5 mph (10 km/h) increments until the lever is released.
The increase in set speed is reflected in the EVIC display.
164 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Tapping the lever up once will result in a 1 mph (1 km/h)
increase in set speed. Each subsequent tap of the lever
results in an increase of 1 mph (1 km/h).
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 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.

Setting the Following Distance in ACC
The specified following distance for ACC can be set by
varying the distance setting between long, medium, and
short. Using this distance setting and the vehicle speed,
ACC calculates and sets the distance to the vehicle ahead.
This distance setting displays in the EVIC.To change the distance setting, push the lever away from
you (DISTANCE) and release. Each time this is done, the
distance setting adjusts between long, medium, and
short.
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 Indi-
cator” icon, and the system adjusts vehicle speed auto-
matically 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.
