Dodge Challenger (2019 year). Manual — part 15

The Cruise Control system has two control modes:
• Adaptive Cruise Control mode for maintaining an ap-

propriate 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:

Normal (Fixed Speed) Cruise Control 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. Al-
ways confirm which mode is selected.

WARNING!

• Adaptive Cruise Control (ACC) is a convenience

system. It is not a substitute for active driving
involvement. It is always the driver’s responsibility
to be attentive of road, traffic, and weather condi-
tions, vehicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to ensure safe
operation of the vehicle under all road conditions.

(Continued)

WARNING! (Continued)

Your complete attention is always required 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).

• Cannot take street, traffic, and weather conditions

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.

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.

Adaptive Cruise Control (ACC) Operation

The Speed Control buttons (located on the right side of the
steering wheel) operates the ACC system.

WARNING!

Leaving the Adaptive Cruise Control (ACC) system on
when not in use is dangerous. You could accidentally
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
instrument cluster display will show 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 show in the

instrument cluster display.

• The system will not be controlling the distance between

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 CANC (cancel) button is pushed.
• The vehicle speed goes below 15 mph (24 km/h).
• An Anti-Lock Brake System (ABS) event occurs.
• The 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.

STARTING AND OPERATING

To Turn Off

The system will turn off and clear the set speed in memory
if:
• The Adaptive Cruise Control (ACC) on/off button is

pushed.

• The Normal (Fixed Speed) Cruise Control on/off button

is pushed.

• The ignition is turned OFF.

To Resume

If there is a set speed in memory push the RES (resume)
button and then remove your foot from the accelerator pedal.
The instrument cluster display will display the last set speed.

NOTE:

ACC cannot be resumed if there is a stationary

vehicle in-front of your vehicle in close proximity.

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

WARNING! (Continued)

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
pushing the SET (+) button.

The driver’s preferred units can be selected through the
instrument cluster display. Refer to “Getting To Know Your
Instrument Panel” for more information. The speed incre-
ment shown is dependant on the chosen speed unit of U.S.
(mph) or Metric (km/h):

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 instrument cluster display.

STARTING AND OPERATING

241

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.

• If the button is continually pushed, 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 instrument cluster display.

To Decrease Speed

While ACC is set, the set speed can be decreased by
pushing the SET (-) button.

The driver’s preferred units can be selected through the
instrument cluster display. Refer to “Getting To Know Your
Instrument Panel” for more information. The speed decre-
ment shown is dependant on the chosen speed unit of U.S.
(mph) or Metric (km/h):

U.S. Speed (mph)
• Pushing the SET (-) button once will result in a 1 mph

decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 mph.

• If the button is continually pushed, the set speed will

continue to decrease in 5 mph increments until the

button is released. The decrease in set speed is reflected
in the instrument cluster 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.

• If the button is continually pushed, the set speed will

continue to decrease in 10 km/h increments until the
button is released. The decrease in set speed is reflected
in the instrument cluster display.

NOTE:
• When you override and push the SET (+) button or SET

(-)

buttons, the new Set Speed will be the current speed

of the vehicle.

• When you use the SET (-) button to decelerate, if the

engine’s braking power does not slow the vehicle suffi-
ciently to reach the set speed, the brake system will
automatically slow the vehicle.

• The ACC system applies the brake down to 15 mph

(24 km/h) when following a target vehicle.

• The ACC system maintains set speed when driving up

hill and down hill. However, a slight speed change on

242

STARTING AND OPERATING

moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill.
This is normal operation and necessary to maintain set
speed. When driving up hill and down hill, the ACC
system will cancel if the braking temperature exceeds
normal range (overheated).

Setting The Following Distance In ACC

The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead. This
distance setting will show in the instrument cluster display.

Distance Setting 4 Bars (Longest)

6

STARTING AND OPERATING

243

Distance Setting 3 Bars (Long)

Distance Setting 2 Bars (Medium)

244

STARTING AND OPERATING

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 “Sensed
Vehicle Indicator” icon, and the system adjusts vehicle speed
automatically to maintain the distance setting, regardless 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.

Distance Setting 1 Bar (Short)

STARTING AND OPERATING

245

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

246

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.

• Do not remove any screws from the sensor. Doing so

could cause an ACC system malfunction or failure and
require a sensor realignment.

6

STARTING AND OPERATING

247

• 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.

248

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.

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.

250

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.

General Information

The following regulatory statement applies to all Radio
Frequency (RF) devices equipped in this vehicle:

This device complies with Part 15 of the FCC Rules and
with Industry Canada license-exempt RSS standard(s).
Operation is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference received, in-

cluding interference that may cause undesired opera-
tion.

NOTE:

Changes or modifications not expressly approved

by the party responsible for compliance could void the
user’s authority to operate the equipment.

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 main-
tain a safe distance between your vehicle and the
vehicle ahead. Always be aware which mode is se-
lected.

To Set A Desired Speed

Turn the Normal (Fixed Speed) Cruise Control
on. When the vehicle has reached the desired
speed, push the SET (+) or SET (-) button and
release. Release the accelerator and the vehicle

will operate at the selected speed. Once a speed has been
