2018 DODGE CHALLENGER Owners Manual

To increase the distance setting, push the Distance Setting —
Increase button and release. Each time the button is pushed,
the distance setting increases by one bar (longer).
To decrease the distance setting, push the Distance Setting —
Decrease button and release. Each time the button is pushed,
the distance setting decreases by one bar (shorter).
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 instrument cluster display will show the “SensedVehicle Indicator” icon, and the system adjusts vehicle
speed automatically to maintain the distance setting, re-
gardless 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.
• The distance setting is changed.
• The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE: The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to maintain
the set distance. If this occurs, a visual alert “BRAKE” will
flash in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity.

STARTING AND OPERATING 231

NOTE:The “Brake!” Screen in the instrument cluster
display is a warning for the driver to take action and does
not necessarily mean that the Forward Collision Warning
system is applying the brakes autonomously.
Overtake Aid
When driving with ACC engaged and following a vehicle,
the system will provide an additional acceleration up to the
ACC set speed to assist in passing the vehicle. This
additional acceleration is triggered when the driver utilizes
the left turn signal and will only be active when passing on
the left hand side.
Adaptive Cruise Control (ACC) Menu
The instrument cluster display will show the current ACC
system settings. The instrument cluster display is located
in the center of the instrument cluster. The information it
displays depends on ACC system status.
Push the Adaptive Cruise Control (ACC) on/off button
(located on the steering wheel) until one of the following
appears in the instrument cluster display:
Adaptive Cruise Control Off
When ACC is deactivated, the display will read “Adaptive
Cruise Control Off.”
Adaptive Cruise Control Ready
When ACC is activated, but the vehicle speed setting has
not been selected, the display will read “Adaptive Cruise
Control Ready.”
Adaptive Cruise Control Set
When the SET (+) or the SET (-) button (located on the
steering wheel) is pushed, the display will read “ACC
SET.”
When ACC is set, the set speed will show in the instrument
cluster display.
Brake Alert
232 STARTING AND OPERATING

The ACC screen may display once again if any ACC
activity occurs, which may include any of the following:
•System Cancel
• Driver Override
• System Off
• ACC Proximity Warning
• ACC Unavailable Warning
• The instrument cluster display will return to the last
display selected after five seconds of no ACC display
activity
Display Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of Vehicle”
Warning
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and also a chime will indicate when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as in
snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud, dirt
or ice. In these cases, the instrument cluster display will
display “ACC/FCW Unavailable Wipe Front Radar Sen-
sor” and the system will deactivate. The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). The ACC system will recover after the
vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active Normal (Fixed Speed) Cruise
Control is still available. For additional information refer to
“Normal (Fixed Speed) Cruise Control Mode” in this
section.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille.
To keep the ACC System operating properly, it is important
to note the following maintenance items:
• Always keep the sensor clean. Carefully wipe the sensor
lens with a soft cloth. Be cautious not to damage the
sensor lens.
6
STARTING AND OPERATING 233

•Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
• If the sensor or front end of the vehicle is damaged due
to a collision, see your authorized dealer for service.
• Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or malfunc-
tion.
When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.
NOTE:
• If the “ACC/FCW Unavailable Wipe Front Radar Sen-
sor” message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other
obstruction, have the radar sensor realigned at your
authorized dealer.
• Installing a snow plow, front-end protector, an aftermar-
ket grille or modifying the grille is not recommended.
Doing so may block the sensor and inhibit ACC/FCW
operation.Service ACC/FCW Warning
If the system turns off, and the instrument cluster displays
“ACC/FCW Unavailable Service Required” or “Cruise/
FCW Unavailable Service Required”, there may be an
internal system fault or a temporary malfunction that
limits ACC functionality. Although the vehicle is still
drivable under normal conditions, ACC will be temporar-
ily unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem persists,
see your authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpectedly.
The driver needs to stay alert and may need to intervene.
Towing A Trailer
Towing a trailer is not advised when using ACC.
234 STARTING AND OPERATING

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 stabil-
ity 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.

STARTING AND OPERATING 235

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 attentive
and ready to apply the brakes if necessary.
ACC Hill Example
Lane Changing Example
236 STARTING AND OPERATING

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) Cruise Control Mode
In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Cruise Control mode is available for cruising
at fixed speeds. The Normal (Fixed Speed) Cruise Control
mode is designed to maintain a set cruising speed without
requiring the driver to operate the accelerator. Cruise
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) Cruise Control off.
Pushing the Normal (Fixed Speed) Cruise Control on/off
button will result in turning on (changing to) the Normal
(Fixed Speed) Cruise Control mode.
WARNING!
In the Normal (Fixed Speed) 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 se-
lected.
