Ram 1500/2500/3500: ParkSense System Usage Precautions


  • Ensure that the front and rear bumper are 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 Front or Rear ParkSense off, the instrument cluster will display "FRONT PARKSENSE OFF" or "REAR PARKSENSE OFF." Furthermore, once you turn Front or Rear ParkSense off, it remains off until you turn it on again, even if you cycle the ignition key.
  • When you move the shift lever to the REVERSE position and Front or Rear ParkSense is turned off, the instrument cluster will display FRONT PARKSENSE OFF or REAR PARKSENSE OFF message for five seconds, followed by a car graphic with OFF in the corresponding side. This car graphic will be displayed 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 obstacle behind or in front of the fascia/bumper, or it could provide a false indication 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 in (45 cm) from the rear fascia/bumper. 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 be displayed in the instrument cluster.
  • On vehicles equipped with a tailgate, ParkSense should be disabled when the tailgate is in the lowered or open position. A lowered tailgate could provide a false indication that an obstacle is behind the vehicle.


  • 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.


  • 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 indication that an obstacle is behind the vehicle.
