(Continued)

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 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.

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

317

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.

WARNING! (Continued)

318 STARTING AND OPERATING

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 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 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.
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.

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/or front

fascia/bumper and the detected obstacle. Refer to “Instru-

ment Cluster Display” in “Getting To Know Your Instru-

ment Panel” for further information.

ParkSense Display

The warning display will turn on indicating the system

status when the vehicle is in REVERSE or when the vehicle is

in DRIVE and an obstacle has been detected.
The system will indicate a detected obstacle by showing a

single arc in the left and/or right rear regions based on the

obstacle’s distance and location relative to the vehicle.

STARTING AND OPERATING

325

(Continued)

• 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 or in

front of the fascia/bumper, or it could provide a false indi-

cation that an obstacle is behind or in front of the fascia/

bumper.

• Use the ParkSense switch to turn the ParkSense system off

if obstacles such as bicycle carriers, trailer hitches, etc. are

placed within 18 inches (45 cm) from the rear fascia/

bumper. Failure to do so can result in the system misinter-

preting a close obstacle as a sensor problem, causing the

“Front/Rear ParkSense Unavailable Service Required”

message to be appear in the instrument cluster display.

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 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
