DODGE CHALLENGER 2021 Owners Manual

STARTING AND OPERATING99
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
While ACC is set, you can increase speed by
pushing the SET (+) button, or decrease speed by
pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
NOTE:When you override and push the SET (+) button or
SET (-) button, the new set speed will be the current
speed of the vehicle.
When ACC Is Active:
NOTE:
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently 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 vehicle
ahead.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on 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 uphill and downhill, 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 Settings

1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

21_LA_OM_EN_USC_t.book Page 99

100STARTING 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 Adaptive Cruise
Control (ACC) Set With Target Vehicle Light, 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 Ú page 97.
The maximum braking applied by ACC is limited;
however, 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.
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.
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 a chime will
sound 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 Sensor”
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, Fixed Speed Cruise
Control is still available.

21_LA_OM_EN_USC_t.book Page 100

STARTING AND OPERATING101
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 malfunc -
tion or failure and require a sensor realignment.
If the sensor or front end of the vehicle is
damaged due to a collision, see an authorized
dealer for service.
Do not attach or install any accessories near the
sensor, including transparent material or after -
market grilles. Doing so could cause an ACC
system failure or malfunction.
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
Sensor” 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 an authorized dealer.
Installing a snow plow, front-end protector, an
aftermarket 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 temporarily
unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem
persists, see an 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. The following are
examples of these types of situations:
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.

Offset Driving Condition Example

21_LA_OM_EN_USC_t.book Page 101

102STARTING AND OPERATING
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 vehicle
detected ahead. 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.
The driver must maintain control of the vehicle,
remain alert, and be ready to apply the brakes if
needed.

Turn Or Bend Example

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 performance may be limited.
NOTE:The driver must maintain control of the vehicle,
remain alert, and be ready to apply the brakes if
needed.
ACC Hill Example

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.
Lane Changing Example

21_LA_OM_EN_USC_t.book Page 102

STARTING AND OPERATING103
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.

Narrow Vehicle Example

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.
Stationary Object And Stationary Vehicle Example
PARKSENSE REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Rear Park Assist system provides
visual and audible indications of the distance
between the rear fascia/bumper and a detected
obstacle when backing up (e.g. during a parking
maneuver).
For limitations of this system and
recommendations, see Ú page 107.
ParkSense will retain the last system state
(enabled or disabled) from the previous ignition
cycle when the ignition is changed to the ON/RUN
position.
ParkSense can be active only when the gear
selector is in REVERSE. If ParkSense is enabled at
this gear selector position, the system will remain
active until the vehicle speed is increased to
approximately 7 mph (11 km/h) or above. The
system will become active again if the vehicle
speed is decreased to speeds less than
approximately 6 mph (9 km/h).

104STARTING AND OPERATING
PARKSENSE SENSORS
The four ParkSense sensors, located in the rear
fascia/bumper, monitor the area behind the
vehicle that is within the sensors’ field of view. The
sensors can detect obstacles from approximately
12 inches (30 cm) up to 79 inches (200 cm) from
the rear fascia/bumper in the horizontal direction,
depending on the location, type and orientation of
the obstacle.
PARKSENSE DISPLAY
When the vehicle is in REVERSE, the warning
display will turn on indicating the system status.
The system will indicate a detected obstacle by
showing a single arc in one or more regions based
on the obstacle’s distance and location relative to
the vehicle.
If an obstacle is detected in the center rear region,
the display will show a single solid arc in the center
rear region and will produce a one-half second
tone. As the vehicle moves closer to the obstacle,
the display will show the single arc moving closer to
the vehicle and the sound tone will change from
slow, to fast, to continuous. If an obstacle is detected in the left and/or right
rear region, the display will show a single flashing
arc in the left and/or right rear region and will
produce a fast sound tone. As the vehicle moves
closer to the obstacle, the display will show the
single arc moving closer to the vehicle and the
sound tone will change from fast to continuous.

PARKSENSE WARNING DISPLAY
The ParkSense Warning screen will only be
displayed if Sound and Display is selected from
within the Uconnect system Úpage 120.
The ParkSense Warning screen is located within
the instrument cluster display Ú page 62. It
provides visual warnings to indicate the distance
between the rear fascia/bumper and the detected
obstacle.
ENABLING AND DISABLING PARKSENSE
ParkSense can be enabled and disabled
with the ParkSense switch, located on
the switch panel below the Uconnect
display.
When the ParkSense switch is pushed to disable
the system, the instrument cluster will display the
“ParkSense Off” message for approximately five
seconds. When the gear selector is moved to
REVERSE and the system is disabled, the
instrument cluster display will display the
“ParkSense Off” message for as long as the vehicle
is in REVERSE.

The ParkSense switch LED will be on when
ParkSense is disabled or requires service. The
ParkSense switch LED will be off when the system is
enabled. If the ParkSense switch is pushed, and the
system requires service, the ParkSense switch LED
will blink momentarily, and then the LED will be on.

SERVICE THE PARKSENSE REAR PARK
A
SSIST SYSTEM
During vehicle start up, when the ParkSense Rear
Park Assist System has detected a faulted
condition, the instrument cluster will actuate a
single chime, once per ignition cycle and it will
display the “PARKSENSE UNAVAILABLE WIPE
REAR SENSORS” or “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message for five seconds.
When the gear selector is moved to REVERSE and
the system has detected a faulted condition, the
instrument cluster display will display the
“PARKSENSE UNAVAILABLE WIPE REAR
SENSORS” or “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message for as long as the
vehicle is in REVERSE. Under this condition,
ParkSense will not operate.
If “PARKSENSE UNAVAILABLE WIPE REAR
SENSORS” appears in the instrument cluster
display, make sure the outer surface and the
inside of the rear fascia/bumper is clean and clear
of snow, ice, mud, dirt or other obstruction, and
then cycle the ignition. If the message continues to
appear see an authorized dealer.
If “PARKSENSE UNAVAILABLE SERVICE
REQUIRED” appears in the instrument cluster
display, see an authorized dealer.
CLEANING THE PARKSENSE SYSTEM
Clean the Rear Park Assist sensors with water, car
wash soap and a soft cloth. Do not use rough or
hard cloths. In washing stations, clean sensors
quickly keeping the vapor jet/high pressure
washing nozzles at least 4 inches (10 cm) from the
sensors. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the rear fascia/bumper is free of
snow, ice, mud, dirt and debris to keep the
ParkSense system operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of
ParkSense or render the system temporarily
unavailable.
When you turn ParkSense off in DRIVE, the
instrument cluster will display "PARKSENSE
OFF" for five seconds. Furthermore, once you
turn ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition.
When you move the gear selector to the
REVERSE position and ParkSense is turned off,
the instrument cluster display will show the
“PARKSENSE OFF” message for as long as the
vehicle is in REVERSE.

21_LA_OM_EN_USC_t.book Page 107

108STARTING AND OPERATING
ParkSense will reduce the volume of the radio
when it is sounding an audio tone.
Clean the ParkSense sensors regularly, taking
care not to scratch or damage them. The
sensors must not be covered with ice, snow,
slush, mud, dirt or debris. Failure to do so can
result in the system not working properly. The
ParkSense system might not detect an obstacle
behind the fascia/bumper, or it could provide a
false indication that an obstacle is behind the
fascia/bumper.
Ensure the ParkSense system is off if objects
such as bicycle carriers, trailer hitches, etc., are
placed within 12 inches (30 cm) from the rear
fascia/bumper. Failure to do so can result in the
system misinterpreting a close object as a
sensor problem, causing the “PARKSENSE
UNAVAILABLE SERVICE REQUIRED” message to
be shown in the instrument cluster display.
PARKVIEW REAR BACK UP CAMERA
The ParkView Rear Back Up Camera allows you to
see an on-screen image of the rear surroundings of
your vehicle whenever the gear selector is put into
REVERSE. The ParkView camera is located on the
rear of the vehicle above the rear license plate. The
image will be displayed in the touchscreen display
along with a caution note to “Check Entire
Surroundings” across the top of the screen. After
five seconds, this note will disappear.
NOTE:The ParkView Rear Back Up Camera has program -
mable modes of operation that may be selected
through the Uconnect system Ú page 120.If your vehicle is equipped with the Camera Delay
feature and it is turned on, the rear camera image
will be displayed for up to 10 seconds when the
vehicle is shifted out of REVERSE. However, this
feature is canceled if the forward vehicle speed
exceeds 8 mph (13 km/h), the transmission is
shifted into PARK, the vehicle's ignition is placed in
the OFF position, or by pressing the image defeat X
button.
When the vehicle is shifted out of REVERSE with
Camera Delay turned off, the rear camera mode is
exited and the last touchscreen appears again.
When enabled, active guidelines are overlaid on
the image to illustrate the width of the vehicle and
its projected backup path based on the steering
wheel position. The active guidelines will show
separate zones that will help indicate the distance
to the rear of the vehicle.
If the vehicle speed remains below 8 mph (13 km/
h), the rear view camera image will continue to be
displayed until the transmission is shifted into
PARK, the vehicle’s ignition is placed in the OFF
position, or the image defeat X button is pressed.
Different colored zones indicate the distance to
the rear of the vehicle.
WARNING!
Drivers must be careful when backing up even
when using the Rear Park Assist system. Always
check carefully behind your vehicle, and be sure
to check for pedestrians, animals, other
vehicles, obstructions, or blind spots before
backing up. You are responsible for the safety of
your surroundings and must continue to pay
attention while backing up. Failure to do so can
result in serious injury or death.
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle, including
small obstacles. Parking curbs might be
temporarily detected or not detected at all.
Obstacles located above or below the sensors
will not be detected when they are in close
proximity.
The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time
when an obstacle is detected. It is recom
-
mended that the driver looks over his/her
shoulder when using ParkSense.
