2015 CHRYSLER 300 Owners Manual

When the condition that created limited functionality is
no longer present, the system will return to full function-
ality.
NOTE:If the “ACC/FCW Limited Functionality Clean
Front Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain, mud, or
other obstruction, have the windshield and forward
facing camera inspected at your authorized dealer.
Service ACC/FCW Warning
If the system turns off, and the DID displays “ACC/FCW
Unavailable Service Required” or “Cruise/FCW Unavail-
able Service Required”, there may be an internal system
fault or a temporary malfunction that limits ACC func-
tionality. Although the vehicle is still drivable under
normal conditions, ACC will be temporarily unavailable.
If this occurs, try activating ACC again later, following an
ignition cycle. If the problem persists, see your autho-
rized 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.
Towing A Trailer
Towing a trailer is not advised when using ACC.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle merging
in from a side lane. There may 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
When driving on a curve with ACC engaged, the system
may decrease the vehicle speed and acceleration for
stability reasons, with no target vehicle detected. Once
the vehicle is out of the curve the system will resume
your original Set Speed. This is a part of normal ACC
system functionality.
NOTE:On tight turns ACC performance may be limited.

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 may 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 not detect the vehicle until it’s too late for the ACC
system to take action. ACC may not detect a vehicle until
it is completely in the lane. There may 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 may not be
sufficient 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.

Normal (Fixed Speed) Electronic Speed Control
Mode
In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Electronic Speed Control mode is available
for cruising at fixed speeds. The Normal (Fixed Speed)
Electronic Speed Control mode is designed to maintain a
set cruising speed without requiring the driver to operate
the accelerator. Electronic Speed Control can only be
operated if the vehicle speed is above 20 mph (32 km/h).
To change between the different control modes, push the
ADAPTIVE CRUISE CONTROL (ACC) ON/OFF button
which turns the ACC and the NORMAL (Fixed Speed)
ELECTRONIC SPEED CONTROL OFF. Pushing of the
NORMAL (Fixed Speed) ELECTRONIC SPEED CON-
TROL ON/OFF button will result in turning ON (chang-
ing to) the Normal (Fixed Speed) Electronic Speed Con-
trol mode.
WARNING!
In the normal Cruise Control mode, the system will
not react to vehicles ahead. In addition, the proximity
warning does not activate and no alarm will sound
even if you are too close to the vehicle ahead since
neither the presence of the vehicle ahead nor the
vehicle-to vehicle distance is detected. Be sure to
maintain a safe distance between your vehicle and
the vehicle ahead. Always be aware which mode is
selected.
To Set A Desired Speed
Turn the Normal (Fixed Speed) Electronic
Speed Control ON. When the vehicle has
reached the desired speed, push the SET (+) or
SET (-) button and release. Release the accel-
erator and the vehicle will operate at the selected speed.
196 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Once a speed has been set a message (CRUISE CON-
TROL SET TO MPH/KM) will appear indicating what
speed was set. This light will turn on when the electronic
speed control is SET.
To Vary The Speed Setting
To Increase Speed
When the Normal (Fixed Speed) Electronic Speed Con-
trol is set, you can increase speed by pushing the SET+
button.
The drivers preferred units can be selected through the

standing Your Instrument Panel” for more information.
The speed increment shown is dependant on the speed of
U.S. (mph) or Metric (km/h) units:
U.S. Speed (mph)
•Pushing the SET+button once will result in a 1 mph
increase in set speed. Each subsequent tap of the
button results in an increase of 1 mph.
•If the button is continually pushed, the set speed will
continue to increase in 5 mph increments until the
button is released. The increase in set speed is reflected
in the DID display.
Metric Speed (km/h)
•Pushing the SET+button once will result in a 1 km/h
increase in set speed. Each subsequent tap of the
button results in an increase of 1 km/h.

continue to decrease in 5 mph decrements until the
button is released. The decrease in set speed is re-
flected in the DID display.
Metric Speed (km/h)
•Pushing the SET-button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 km/h.
