warning Ram 3500 2019 Owner's Manual

STARTING AND OPERATING 371
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” 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 functionality is no
longer present, the system will return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean Front Wind -
shield” message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other obstruc -
tion, 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 drivable
under normal conditions, ACC will be temporarily unavail
-
able. 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.
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 performance and functionality.

376 STARTING AND OPERATING
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. Speed 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 on and the Normal (Fixed Speed) Cruise Control
off. Pushing of the Normal (Fixed Speed) Cruise Control on/
off button will result in turning on (changing to) the Normal
(Fixed Speed) Cruise Control mode.To Set A Desired Speed
Turn the Normal (Fixed Speed) Cruise Control on.
When the vehicle has reached the desired speed,
push the RES (+) or SET (-) button and release.
Release the accelerator and the vehicle will operate at the
selected speed. Once a speed has been set a message
“CRUISE CONTROL SET TO MPH (km/h)” will appear
indicating what speed was set. This light will turn on when
the system is turned on via the on/off control. It turns green
when the cruise control is set.
To Vary The Speed Setting
To Increase Speed
When the Normal (Fixed Speed) Cruise Control is set, you
can increase speed by pushing the RES (+) button.
The driver's preferred units can be selected through the
instrument panel settings. Refer to ”Instrument Cluster
Display” in “Getting To Know Your Instrument Panel” for
more information. The speed increment shown is dependant
on the speed of U.S. (mph) or Metric (km/h) units:
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 selected.

STARTING AND OPERATING 379
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
recommendations.
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 can be active only when the gear selector is in
REVERSE. If ParkSense is enabled at this gear selector posi-
tion, 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 approximately 6 mph (9 km/h).
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
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:
If equipped as a dually, the ParkSense system has six rear
sensors to assist in detection around the dually flares.

380 STARTING AND OPERATING
ParkSense Warning Display
The ParkSense Warning screen is located within the instru-
ment cluster display. It provides visual warnings to indicate
the distance between the rear fascia/bumper and the
detected obstacle. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further infor-
mation.
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 the left and/or right rear regions based on the
object’s distance and location relative to the vehicle.
If an object is detected in the left and/or right rear region, the
display will show a single solid arc in the left and/or right
rear region and the system will produce a tone. As the
vehicle moves closer to the object, the display will show the
single arc moving closer to the vehicle and the tone will
change from a single 1/2 second tone to slow, to fast, to
continuous.

384 STARTING AND OPERATING
The vehicle is close to the obstacle when the warning display shows one flashing arc and sounds a continuous tone. The
following chart shows the warning alert operation when the system is detecting an obstacle:
NOTE:
ParkSense will reduce the volume of the radio, if on, when
the system is sounding an audio tone.Adjustable Chime Volume Settings
The rear chime volume settings are programmable through
the Uconnect system. Refer to “Uconnect Settings” in “Multi
-
media” for further information.
The chime volume settings include low, medium, and high.
The factory default volume is medium.

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, dirtand debris to keep the ParkSense system operating prop -
erly.
• Jackhammers, large trucks, and other vibrations could affect the performance of ParkSense.
• 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 properly. The Park -Sense 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
18 inches (45 cm) of the rear fascia/bumper while driving
the vehicle. Failure to do so can result in the system misin -
terpreting a close obstacle as a sensor problem, causing the
"Rear ParkSense Unavailable Service Required" message
to appear in the instrument cluster display.
• On vehicles equipped with a tailgate, ParkSense should be disabled when the tailgate is in the lowered or open posi -
tion and the vehicle is in REVERSE. A lowered tailgate
could provide a false indication that an obstacle is behind
the vehicle.
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.

STARTING AND OPERATING 387
PARKSENSE FRONT AND REAR PARK ASSIST
The ParkSense 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 Precautions” in this
section for limitations of this system and recommendations.
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 can be active only when the gear selector is in
REVERSE or DRIVE. If ParkSense is enabled at one of these
gear selector positions, the system will remain active until
the vehicle speed is increased to approximately 7 mph
(11 km/h) or above. A warning will appear in the instrument
cluster display when the vehicle is in REVERSE, indicating
the vehicle is above ParkSense operating speed. The system
will become active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h).
• Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly is discon -
nected 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 indication 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 Park -
Sense 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.
