2015 DODGE CHALLENGER Owners Manual

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 vehicles,
and stationary objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).

WARNING!(Continued)
•Cannot take street, traffic, and weather condi-
tions into account, and may be limited upon
adverse sight distance conditions.
•Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.
•Will bring the vehicle to a complete stop while
following a target vehicle and hold the vehicle
for 2 seconds in the stop position. If the target
vehicle does not start moving within two seconds
the ACC system will display a message that the
system will release the brakes and that the
brakes must be applied manually. An audible
chime will sound when the brakes are released.
(Continued)
WARNING!(Continued)
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.
When towing a trailer up or down steep slopes.
When circumstances do not allow safe driving at a
constant speed.
The Cruise Control system has two control modes:
•Adaptive Cruise Control mode for maintaining an
appropriate distance between vehicles.
160 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•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 or tire size modifications
to the vehicle will effect the performance of the Adaptive
Cruise Control and Forward Collision Warning System.
Activating Adaptive Cruise Control (ACC)
You can only engage ACC if the vehicle speed is above
20 mph (32 km/h).
The system will cancel when the vehicle speed drops
below 15 mph (24 km/h).
The minimum Set Speed for the ACC system is 20 mph
(32 km/h).
When the system is turned on and in the READY state,
the Driver Information Display (DID) displays “ACC
Ready.”
When the system is OFF, the DID displays “Adaptive
Cruise Control (ACC) Off.”
NOTE:You cannot engage 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 Vehicle speed is outside of the speed range.
•When the brakes are overheated.
To Activate/Deactivate
Push and release the Adaptive Cruise Control (ACC)
ON/OFF button. The ACC menu in the DID displays
“ACC Ready.”
162 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

To turn the system OFF, push and release the Adaptive
Cruise Control (ACC) ON/OFF button again. At this
time, the system will turn off and the DID will display
“Adaptive Cruise Control (ACC) 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 or the SET-button and release. The DID
will display the set speed.
If the system is Set when the vehicle speed is above
20 mph (32 km/h), the Set Speed shall be the current
speed of the 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 DID.
•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 following conditions cancel the system:
•The brake pedal is applied.
•The CANCEL button is pressed.
•The vehicle speed goes below 15 mph (25 km/h).
•An Anti-Lock Brake System (ABS) event occurs.
•The shift lever/gear selector is removed from the
Drive position.
•The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.
•The vehicle parking brake is applied.
164 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•A Trailer Sway Control (TSC) event occurs.
•The driver switches ESC to full-off mode.
To Turn Off
The system will turn off and erase the set speed in
memory if:
•The Normal (Fixed Speed) Electronic Speed Control
ON/OFF button is pressed.
•The ignition is turned off.
•The Adaptive Cruise Control (ACC) On/Off button is
pressed.
To Resume
If there is a set speed in memory press the RES (resume)
button and then remove your foot from the accelerator
pedal. The DID 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. Failure to
follow these warnings can result in a collision and
death or serious personal injury.
To Vary The Speed Setting
To Increase Speed
While ACC is set, you can increase the set speed by
pressing the SET+button.

The speed increment shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
•Pressing the SET+button once will result ina1mph
increase in set speed. Each subsequent tap of the
button results in an increase of 1 mph.
•If the button is continually pressed, 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.
Metric Speed (km/h)
•Pressing 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.
•If the button is continually pressed, the set speed will
continue to increase in 10 km/h increments until the
button is released. The increase in set speed is reflected
in the DID.
To Decrease Speed
While ACC is set, the set speed can be decreased by
pressing the SET-button.
The speed decrement shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
•Pressing the SET-button once will result ina1mph
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 mph.
•If the button is continually pressed, the set speed will
continue to decrease in 5 mph increments until the
button is released. The decrease in set speed is re-
flected in the DID.
