2020 RAM CHASSIS CAB instrument cluster

STARTING AND OPERATING241
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.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean
Front Windshield” warning will display and also
a chime will indicate when conditions tempo -
rarily limit system performance. This most often
occurs at times of poor visibility, such as in
snow or heavy rain and fog. The ACC system
may also become temporarily blinded due to
obstructions, such as mud, dirt, or ice on wind -
shield, driving directly into the sun and fog on
the inside of glass. In these cases, the instru -
ment cluster display will show “ACC/FCW
Limited Functionality Clean Front Windshield”
and the system will have degraded perfor -
mance.
The “ACC/FCW Limited Functionality Clean
Front Windshield” message can sometimes be
displayed while driving in adverse weather
conditions. The ACC/FCW system will recover
after the vehicle has left these areas. Under
rare conditions, when the camera is not
tracking any vehicles or objects in its path this
warning may temporarily occur. If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rear view
mirror. They may require cleaning or removal of
an obstruction.
When the condition that created limited func
-
tionality is no longer present, the system will
return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean
Front Windshield” message occurs frequently
(e.g. more than once on every trip) without any
snow, rain, mud, or other obstruction, have the
windshield and forward facing camera
inspected at your authorized dealer.
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 driv -
able under normal conditions, ACC will be
temporarily unavailable. If this occurs, try acti -
vating ACC again later, following an ignition
cycle. If the problem persists, see your autho -
rized 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.
NOTE:
Aftermarket add-ons such as snow plows, lift
kits, and brush/grille bars can hinder module
performance. Ensure the radar/camera has
no obstructions in the field of view.
Height modifications can limit module perfor -
mance and functionality.
Do not put stickers or easy passes over the
camera/radar field of view.
Any modifications to the vehicle that may
obstruct the field of view of the radar/camera
are not recommended.
Cleaning Instructions
Dust and dirt can accumulate on the cover and
block the camera lens. Clean the camera lens
with a soft microfiber cloth, being careful not to
damage or scratch the module.

PARKSENSE REAR PARK ASSIST — IF
EQUIPPED
The ParkSense Rear Park Assist system
provides visual and audible indications of the
distance between the rear fascia and a
detected obstacle when backing up (e.g. during
a parking maneuver). Refer to “ParkSense
System Usage Precautions” in this section for
limitations of this system and recommenda -
tions.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition cycle
when the ignition is changed to the ON/RUN
position.
ParkSense Rear Park Assist can be active only
when the gear selector is in REVERSE. If Park -
Sense 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. When in REVERSE and
above the system's operating speed, a warning will appear within the instrument cluster display
indicating the vehicle speed is too fast. The
system will become active again if the vehicle
speed is decreased to speeds less than approx
-
imately 6 mph (9 km/h).
ParkSense Sensors
For the 3500, 4500 and 5500 Chassis Cab
vehicles, the rear ParkSense sensors are
shipped loose. Please refer to the Ram Body
Builder’s Guide for more information.
The four ParkSense sensors are to be located in
the rear fascia/bumper, and monitor the area
behind the vehicle that is within the sensors’
field of view.
The sensors can detect obstacles from approxi -
mately 18 inches (45 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.
NOTE:

Service The ParkSense Rear Park Assist
System
During vehicle start up, when the Rear Park -
Sense System has detected a faulted condition,
the instrument cluster display will show the
"Rear ParkSense Unavailable Service Required"
or the "Rear ParkSense Unavailable Wipe
Sensors" message.
When the gear selector is moved into REVERSE,
a vehicle graphic will show in the instrument
cluster display, along with the display overlay
“Rear ParkSense Unavailable Wipe Sensors.” If
the system needs service, the display overlay
will read “Rear ParkSense Unavailable Service
Required” Under this condition, ParkSense will
not operate. If "Rear ParkSense Unavailable Wipe Sensors"
appears in the instrument cluster display make
sure the outer surface and the underside 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 "Rear ParkSense Unavailable Service
Required" appears in the instrument cluster
display, see an authorized dealer.Cleaning The ParkSense System
Clean the ParkSense sensors with water, car
wash soap and a soft cloth. Do not use rough or
hard cloths. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
ParkSense System Usage Precautions
NOTE:
Ensure that the rear bumper is free of snow,
ice, mud, dirt and debris to keep the Park
-
Sense system operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of Park -
Sense.

250STARTING AND OPERATING
When you move the gear selector into
REVERSE with ParkSense turned off, the
instrument cluster display will show "Off" on
the vehicle graphic arcs for as long as the
vehicle is in REVERSE.
ParkSense, when on, will reduce the volume
of the radio when it is sounding a 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 prop -
erly. 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 on the fascia/bumper while
driving the vehicle. Failure to do so can result
in the system misinterpreting a close
obstacle as a sensor problem, causing the
“Wipe Sensors” message or providing false
alerts.
PARKSENSE FRONT AND REAR PARK ASSIST
The ParkSense Front and Rear Park Assist
system provides visual and audible indications
of the distance between the rear, and/or front
fascia/bumper, and a detected obstacle when
backing up or moving forward (e.g. during a
parking maneuver).
Refer to “ParkSense System Usage Precau -
tions” in this section for limitations of this
system and recommendations.
WARNING!
Drivers must be careful when backing up
even when using ParkSense. Always check
carefully behind your vehicle, look behind
you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and
blind spots before backing up. You are
responsible for safety and must continue to
pay attention to your surroundings. Failure
to do so can result in serious injury or
death.
Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly is disconnected from
the vehicle when the vehicle is not used for
towing. Failure to do so can result in injury
or damage to vehicles or obstacles
because the hitch ball will be much closer
to the obstacle than the rear fascia when
the loudspeaker sounds the continuous
tone. Also, the sensors could detect the ball
mount and hitch ball assembly, depending
on its size and shape, giving a false indica -
tion that an obstacle is behind the vehicle.
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
recommended that the driver looks over
his/her shoulder when using ParkSense.
