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 of the rear
regions (left/center/right) based on the object’s
distance and location relative to the vehicle.
If an object is detected in one or more of the
rear regions, the display will show a single solid
arc in these regions 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.

with trailer brakes has been connected to the
Integrated Trailer Brake Module. The instru -
ment cluster display will show an “Off” message
over the arcs if the ParkSense system is off, or
a “Trailer” message if the system is on, for as
long as the vehicle is in REVERSE. The ParkSense switch LED will be on when Park
-
Sense is disabled or defective. The ParkSense
switch LED will be off when the system is
enabled.
If the ParkSense switch is pushed, and the
system is disabled or requires service, the Park -
Sense switch LED will blink momentarily, and
then the LED will be on.
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.

STARTING AND OPERATING251
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 Park -
Sense operating speed. The system will become
active again if the vehicle speed is decreased to
speeds less than approximately 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:
If equipped as a dually, the ParkSense system
has six rear sensors to assist in detection
around the dually flares.
The six ParkSense sensors, located in the front
fascia/bumper, monitor the area in front of the
vehicle that is within the sensors’ field of view.
The sensors can detect obstacles from approxi -
mately 12 inches (30 cm) up to 47 inches
(120 cm) from the front fascia/bumper in the
horizontal direction, depending on the location,
type and orientation of the obstacle.ParkSense Warning Display
The ParkSense Warning screen is located within
the instrument cluster display. It provides visual
warnings to indicate the distance between the
rear fascia/bumper and/or front fascia/bumper
and the detected obstacle. Refer to “Instrument
