CHRYSLER 300 2012 2.G Owners Manual

On steep hills, a greater speed loss or gain may occur so
it may be preferable to drive without Electronic Speed
Control.
WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions, and you
could lose control and have an accident. Do not use
Electronic Speed Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.
ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by cruise control while traveling
on highways and major roadways. However, it is not a
safety system and not designed to prevent collisions.
ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constant
need to reset your cruise control. ACC utilizes a radar
sensor designed to detect a vehicle directly ahead of you.
NOTE:
•If the sensor does not detect a vehicle ahead of you,
ACC will maintain a fixed set speed.
•If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed
the original set speed) automatically to maintain a
preset following distance, while matching the speed of
the vehicle ahead.

WARNING!
•Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibil-
ity to be attentive of road, traffic, and weather
conditions, vehicle speed, distance to the vehicle
ahead; and, most importantly, brake operation to
ensure safe operation of the vehicle under all road
conditions. Your complete attention is always re-
quired while driving to maintain safe control of
your vehicle. Failure to follow these warnings can
result in a collision and death or serious personal
injury.
•The ACC system:
Does not react to pedestrians, oncoming ve-
hicles, and stationary objects (e.g., a stopped ve-
hicle in a traffic jam or a disabled vehicle).
(Continued)
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 compensate
for such changes.
Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.
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
(e.g., 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.
•When towing a trailer up or down steep slopes.
•When circumstances do not allow safe driving at a
constant speed.
Failure to follow these warnings can result in a
collision and death 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 is for cruis-
ing at a constant preset speed. For additional informa-
tion, 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 Cruise Control
buttons. The two control modes function differently.
Always confirm which mode is selected.

Adaptive Cruise Control (ACC) Operation
The speed control buttons (located on the right side of the
steering wheel) operates the ACC system.NOTE:Any chassis/suspension modifications to the
vehicle will effect the performance of the Adaptive Cruise
Control.
Activating Adaptive Cruise Control (ACC)
You can only activate ACC if the vehicle speed is above
20 mph (32 km/h).
When the system is turned on and in the READY state,
the Electronic Vehicle Information Center (EVIC) dis-
plays “Adaptive Cruise Ready.”
When the system is OFF, the EVIC displays “Adaptive
Cruise Control 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 pushing the RES+button without a previously
set speed in memory.
To Activate
Push and release the ON/OFF button. The ACC menu in
the EVIC displays “Adaptive Cruise Ready.”

To turn the system OFF, push and release the ON/OFF
button again. At this time, the system will turn off and
the EVIC will display “Adaptive Cruise Control 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 a collision.
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
SET-button and release. The EVIC will display the set
speed.

204 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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.
•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 press the CANCEL switch.
•An Anti-Lock Brake System (ABS) event occurs.
•If the transmission is shifted into NEUTRAL.
•The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.
NOTE:If ACC is resumed or set with the ESC/TCS off,
ESC will automatically be re-engaged.
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.

To Resume Speed
Press the RES+button and release. Then remove your
foot from the accelerator pedal. The EVIC will display the
last set speed.
NOTE:You can resume ACC from a minimum of
20 mph (32 km/h).
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. Failure to
follow these warnings can result in a collision and
death or serious personal injury.
To Vary The Speed Setting
While ACC is set, you can increase the set speed by
pressing and holding the RES+button. If the button is
continually pressed, the set speed will continue to in-
crease in 5 mph (8 km/h) increments until the button is
released. The increase in set speed is reflected in the EVIC
display.
Pressing the RES+button once will result ina1mph
(1.6 km/h) increase in set speed. Each subsequent tap of
the button results in an increase of 1 mph (1.6 km/h).
While ACC is set, the set speed can be decreased by
pressing and holding the SET-button. If the button is
continually pressed, the set speed will continue to de-
crease in 5 mph (8 km/h) increments until the button is
released. The decrease in set speed is reflected in the
EVIC display.

Pressing the SET-button once will result ina1mph
(1.6 km/h) decrease in set speed. Each subsequent tap of
the button results in a decrease of 1 mph (1.6 km/h).
NOTE:
•When you use the SET-button to decelerate, if the
engine’s braking power does not slow the vehicle
sufficiently to reach the set speed, the brake system
will automatically 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.
Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between 3 (long), 2 (me-
dium), and 1 (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.
