2010 CHRYSLER 300 Owners Manual

NOTE:
•Electronic Speed Control will only function in 3rd, 4th,
or 5th gear when in the Autostickmode (if
equipped).
•The Electronic Speed Control may not engage if a
different size tire is installed on one wheel, such as the
compact spare tire.
To Deactivate
The system will disable Electronic Speed Control without
erasing the memory if you:
•Softly tap the brake pedal.
•Press the brake pedal.
•Pull the Electronic Speed Control lever toward you
(CANCEL).
Pushing and releasing the ON/OFF button or turning the
ignition OFF erases the set speed from memory.
To Resume Speed
If you deactivated the Electronic Speed Control without
erasing the set speed from memory and your vehicle
speed is above 20 mph (32 km/h) you can resume the
previous set speed. To do so, push the lever upward to
RESUME ACCEL and release. Then remove your foot
from the accelerator pedal.
To Vary the Speed Setting
When the Electronic Speed Control is set, you can in-
crease speed by pushing up and holding the RESUME
ACCEL lever. If the lever is continually held in the
RESUME ACCEL position, the set speed will continue to
increase until the lever is released, then the new set speed
will be established.
Tapping the Electronic Speed Control lever to RESUME
ACCEL once will result in a 1 mph (1.6 km/h) speed
increase. Each time the lever is tapped speed increases, so
tapping the lever three times will increase speed by
3 mph (4.8 km/h), etc.
160 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

To decrease speed while Electronic Speed Control is set,
push down and hold the lever in SET DECEL. If the lever
is continually held in the SET DECEL position, the set
speed will continue to until the lever is released. Release
the lever when the desired speed is reached, and a new
set speed will be established.
Tapping the Electronic Speed Control lever to SET DE-
CEL once will result in a 1 mph (1.6 km/h) speed
decrease. Each time the lever is tapped, speed decreases.
To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Electronic Speed Control on Hills
NOTE:The Electronic Speed Control system maintains
speed up and down hills. A slight speed change on
moderate hills is normal. The automatic transmission will downshift while climb-
ing uphill or descending downhill. This downshift is
necessary to maintain vehicle set speed.
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. An accident could be the result.
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 an infrared
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 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 an accident or serious personal injury.The
ACC system:
•Does not react to pedestrians, oncoming vehicles,
and stationary objects (i.e., a stopped vehicle in a
traffic jam or a disabled vehicle).(Continued)
162 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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).

4 — ON/OFF/MODE
5 — SET/DECEL

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.
166 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.3
