REVERSE and the system is disabled, the instrument
cluster display will show the “PARKSENSE OFF” message
for as long as the vehicle is in REVERSE. NOTE:
The ParkSense system will automatically disable
when the system detects that a trailer with trailer brakes
has been connected to the Integrated Trailer Brake Module.
The instrument cluster display will show 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 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 ParkSense 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 ParkSense Rear Park
Assist System has detected a faulted condition, the instru-
ment cluster display will actuate a single chime, once per
ignition cycle, and it will show the PARKSENSE UN-
AVAILABLE WIPE REAR SENSORS or thePARKSENSE
UNAVAILABLE SERVICE REQUIRED message. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information. When the gear
selector is moved to REVERSE and the system has detected
a faulted condition, the instrument cluster display will

show thePARKSENSE UNAVAILABLE WIPE REAR SEN-
SORS or thePARKSENSE UNAVAILABLE SERVICE RE-
QUIRED message for as long as the vehicle is in RE-
VERSE. 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 underside of the rear fascia/bumper
is clean and clear of snow, ice, mud, dirt or other obstruc-
tion, and then cycle the ignition. If the message continues
to appear, see your authorized dealer.
If PARKSENSE UNAVAILABLE SERVICE REQUIRED 
appears in the instrument cluster display, see your autho-
rized 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 ParkSense system operating
properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
• When you turn ParkSense off, the instrument cluster
display will show PARKSENSE OFF. Furthermore,
once you turn ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition key.
• When you move the gear selector to the REVERSE
position and ParkSense is turned off, the instrument
cluster display will show the PARKSENSE OFFmes-
sage 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 ParkSense system might not detect an
278 STARTING AND OPERATING

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) from the rear fascia/bumper while driv-
ing the vehicle. Failure to do so can result in the system
misinterpreting a close obstacle as a sensor problem,
causing the 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
position 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,

WARNING! (Continued)
and blind spots before backing up. You are respon-
sible 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 con-
tinuous 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
(Continued)

CAUTION!(Continued)
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.
PARKSENSE FRONT AND REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear and/or
front fascia 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 instru-
ment cluster display 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).
ParkSense Sensors
For the 3500, 4500 and 5500 Chassis Cab vehicles, the rear
ParkSense sensors are shipped loose. Please refer to the
Ram Body Builders Guide for more information.
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 direc-
tion, depending on the location, type and orientation of the
obstacle.
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 approximately 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.
