2021 DODGE CHALLENGER warning

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.

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.

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.

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.

WARNING!
Drivers must be careful when backing up even
when using the ParkView Rear Back Up Camera.
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!
To avoid vehicle damage, ParkView should
only be used as a parking aid. The ParkView
camera is unable to view every obstacle or
object in your drive path.
To avoid vehicle damage, the vehicle must be
driven slowly when using ParkView to be able
to stop in time when an obstacle is seen. It is
recommended that the driver look frequently
over his/her shoulder when using ParkView.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.

STARTING AND OPERATING111
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do not
exceed either front or rear GAWR.
OVERLOADING
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide
satisfactory service as long as you do not exceed
the GVWR and the front and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and
ready for operation. Weigh it on a commercial scale
to ensure that it is not over the GVWR.
Figure out the weight on the front and rear of the
vehicle separately. It is important that you
distribute the load evenly over the front and rear
axles. Overloading can cause potential safety hazards
and shorten useful service life. Heavier axles or
suspension components do not necessarily
increase the vehicle's GVWR.
LOADING
To load your vehicle properly, first figure out its
empty weight, axle-by-axle and side-by-side. Store
heavier items down low and be sure you distribute
their weight as evenly as possible. Stow all loose
items securely before driving. If weighing the
loaded vehicle shows that you have exceeded
either GAWR, but the total load is within the
specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse
effect on the way your vehicle steers and handles
and the way the brakes operate.
NOTE:Refer to the Vehicle Certification Label affixed to
the rear of the driver's door for your vehicle's GVWR
and GAWRs Ú
page 110.
TRAILER TOWING
In this section, you will find safety tips and
information on limits to the type of towing you can
reasonably do with your vehicle. Before towing a
trailer, carefully review this information to tow your
load as efficiently and safely as possible. To maintain warranty coverage, follow the
requirements and recommendations in this
manual concerning vehicles used for trailer towing.
Manual Transmission — If Equipped
Trailer towing with this vehicle is not
recommended.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will
assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo
and tongue weight. The total load must be limited
so that you do not exceed the GVWR Ú
page 110.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight
of all cargo, consumables, and equipment
(permanent or temporary) loaded in or on the
trailer in its "loaded and ready for operation"
condition.
The recommended way to measure GTW is to put
your fully loaded trailer on a vehicle scale. The
entire weight of the trailer must be supported by
the scale.
WARNING!
Because the front wheels steer the vehicle, it is
important that you do not exceed the maximum
front or rear GAWR. A dangerous driving
condition can result if either rating is exceeded.
You could lose control of the vehicle and have a
collision.
4

21_LA_OM_EN_USC_t.book Page 111

112STARTING AND OPERATING
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your
vehicle and trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do not
exceed either front or rear GAWR Ú page 110.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch
ball by the trailer. You must consider this as part of
the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied
by the maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that
can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion to
dampen any unwanted trailer swaying motions
while traveling.
If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch
ball or some other connecting point of the vehicle.
These kinds of hitches are commonly used to tow
small and medium sized trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute trailer
tongue weight to the tow vehicle's front axle and
the trailer axle(s). When used in accordance with
the manufacturer's directions, it provides for a
more level ride, offering more consistent steering
and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway control also dampens sway caused by traffic and
crosswinds and contributes positively to tow
vehicle and trailer stability. Trailer sway control and
a weight distributing (load equalizing) hitch are
recommended for heavier Tongue Weights (TW)
and may be required depending on vehicle and
trailer configuration/loading to comply with Gross
Axle Weight Rating (GAWR) requirements.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the vehicle
and have a collision.
WARNING!
An improperly adjusted Weight Distributing
Hitch system may reduce handling, stability,
braking performance, and could result in a
collision.
Weight Distributing Systems may not be
compatible with Surge Brake Couplers.
Consult with your hitch and trailer manufac-
turer or a reputable Recreational Vehicle
dealer for additional information.
