2022 Jeep Grand Cherokee ParkSense Front/Rear Park Assist System User Guide
PARKSENSE FRONT/REAR PARK ASSIST SYSTEM — IF EQUIPPED
The ParkSense Park Assist system provides visual and audible indications of the distance between the rear, and if equipped, the front fascia/bumper and a detected obstacle when backing up or moving forward (e.g. during a parking maneuver). The vehicle brakes may be automatically applied and released when performing a reverse parking maneuver if the system detects a possible collision with an obstacle.
NOTE:
- The driver can disable the automatic braking function by turning ParkSense off via the Park-Sense switch. The driver can also override automatic braking by changing the gear or by pressing the gas pedal over 90% of its capacity during the braking event.
- Automatic brakes are not available if the vehicle is in 4WD Low.
- Automatic brakes will not be available if there is a faulted condition detected with the ParkSense Park Assist system or the Braking System Module.
- The automatic braking function may only be applied if the vehicle deceleration is not enough to avoid colliding with a detected obstacle.
- The automatic braking function may not be applied fast enough for obstacles that move toward the rear of the vehicle from the left and/or right sides.
- The automatic braking function can be enabled/disabled from the Customer Programmable Features section of the Uconnect system.
- ParkSense will retain its last known configuration state for the automatic braking function through ignition cycles.
The automatic braking function is intended to assist the driver in avoiding possible collisions with detected obstacles when backing up in REVERSE gear.
NOTE:
- The system is designed to assist the driver and not to substitute the driver.
- The driver must stay in full control of the vehicle’s acceleration and braking and is responsible for the vehicle’s movements.
For limitations of this system and recommendations, see Ú page 168.
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. The system will become active again if the vehicle speed is decreased to speeds less than approximately 6 mph (9 km/h). A display warning will appear in the instrument cluster display if the vehicle is in REVERSE and the speed exceeds 7 mph (11 km/h).
PARKSENSE SENSORS
The four ParkSense sensors located in the rear fascia/bumper, and the six ParkSense sensors located in the front fascia/bumper, monitor the area in front and behind the vehicle that is within the sensors’ field of view. The front sensors detect obstacles from approximately 12 inches (30 cm) up to 47 inches (120 cm) from the front fascia/bumper. The rear sensors can detect obstacles from approximately 12 inches (30 cm) up to 79 inches (200 cm) from the rear fascia/bumper. These distances depend on the location, type and orientation of the obstacle in the horizontal direction.
NOTE:
If the vehicle is equipped with ParkSense Active Park Assist, there will be six ParkSense sensors located in the rear fascia/bumper.
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 front or 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 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.

Adjustable Chime Volume Settings
Front and rear chime volume settings can be selected from the Uconnect system Ú page 204.
The chime volume settings include low, medium, and high.
ParkSense will retain its last known configuration state through ignition cycles.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen is located within the instrument cluster display Ú page 99. It provides visual warnings to indicate the distance between the rear fascia/bumper and/or front fascia/bumper and the detected obstacle.
ENABLING AND DISABLING PARKSENSE
ParkSense can be enabled and disabled with the ParkSense switch located on the switch back above the Uconnect display.
When the ParkSense switch is pushed to enable the system, the instrument cluster will display the system state.
When the ParkSense switch is pushed to disable the system, the instrument cluster will display the “PARKSENSE OFF” message for approximately two seconds. When the gear selector is moved to REVERSE and the system is disabled, the instrument cluster display will display the “PARKSENSE OFF” message for as long as the vehicle is in REVERSE.
NOTE:
When ParkSense is disabled and the gear selector is moved to the DRIVE position, no warning message will be displayed.
The ParkSense switch LED will be on when ParkSense is disabled or requires service. The ParkSense switch LED will be off when the system is enabled. If the ParkSense switch is pushed, and the system requires service, the ParkSense switch LED will blink momentarily, and then the LED will be on.
SERVICE THE PARKSENSE PARK ASSIST SYSTEM
During vehicle start-up, when the ParkSense System has detected a faulted condition, the instrument cluster will actuate a single chime, once per ignition cycle, and it will display a pop-up. The pop-up will include up to two faults. Possible fault messages are “PARKSENSE UNAVAILABLE WIPE REAR SENSORS”, “PARKSENSE UNAVAILABLE WIPE FRONT SENSORS”, or “PARKSENSE UNAVAILABLE SERVICE REQUIRED.” The pop-up message will display for five seconds.
When the gear selector is moved to REVERSE and the system has detected a faulted condition, the instrument cluster display will display a “PARKSENSE UNAVAILABLE WIPE REAR SENSORS”, “PARKSENSE UNAVAILABLE WIPE FRONT SENSORS” or “PARKSENSE UNAVAILABLE SERVICE REQUIRED” pop-up message for five seconds. After five seconds, a vehicle graphic will be displayed with “UNAVAILABLE” at either the front or rear sensor location depending on where the fault is detected. The system will continue to provide arc alerts for the side that is functioning properly. These arc alerts will interrupt the “PARKSENSE UNAVAILABLE WIPE REAR SENSORS”, “PARKSENSE UNAVAILABLE WIPE FRONT SENSORS”, or “PARKSENSE UNAVAILABLE SERVICE REQUIRED” messages if an object is detected within the five second pop-up duration.
The vehicle graphic will remain displayed for as long as the vehicle is in REVERSE.
If “PARKSENSE UNAVAILABLE WIPE REAR SENSORS” or “PARKSENSE UNAVAILABLE WIPE FRONT SENSORS” appears in the instrument cluster display make sure the outer surface and the underside of the rear fascia/bumper and/or front 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 the “PARKSENSE UNAVAILABLE SERVICE REQUIRED” message 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.
PARKSENSE SYSTEM USAGE PRECAUTIONS
NOTE:
- 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 ParkSense off, the instrument cluster will display “PARKSENSE OFF.” Furthermore, once you turn ParkSense off, it remains off until you turn it on again, even if you cycle the ignition.
- When you move the gear selector to the REVERSE position and ParkSense is turned off, the instrument cluster will display “PARKSENSE OFF” 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 objects such as bicycle carriers, trailer hitches, etc., are placed within 12 inches (30 cm) of the rear fascia/bumper. Failure to do so can result in the system misinterpreting a close object as a sensor problem, causing the “PARKSENSE UNAVAILABLE SERVICE REQUIRED” message to be displayed in the instrument cluster.
- ParkSense should be disabled when the liftgate is in the open position. An opened liftgate 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.
- Before using ParkSense, it is strongly recommended that the ball mount and hitch ball assembly be 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 vehicle 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 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.
SIDE DISTANCE WARNING SYSTEM
The Side Distance Warning system detects the presence of side obstacles near the vehicle using the parking sensors located in the front and rear fascia/bumpers.
Side Distance Warning Display
The Side Distance Warning screen will only be displayed if this feature is enabled within Uconnect Settings page 204.
The system warns the driver with an acoustic signal and, when enabled, with visual indications on the instrument cluster display.
When the vehicle is in DRIVE, the Side Distance Warning volume/chime will match the Front ParkSense volume and chime type.
When the vehicle is in REVERSE, the Side Distance Warning volume/chime will match the Rear ParkSense volume and chime type.

NOTE:
Parksense will reduce the volume of the radio if on when the system is sounding an audible tone. An audible tone will only sound if a collision is possible.
Activation/Deactivation
The system can operate only after driving a short distance and if the vehicle speed is between 0 and 7 mph (0 and 11 km/h). The system can be activated/deactivated via the Settings menu of the Uconnect system. If the ParkSense System is deactivated via the ParkSense hard switch, then the Side Distance Warning system will automatically be deactivated.
Message on the display for Side Distance Warning feature: “Wipe Sensors” — This message is displayed in the case of a failure of the Side Distance Warning system sensors. Free the bumpers of any obstacles, ensure that the front and rear fascia/bumper are free of snow, ice, mud, dirt and debris to keep the ParkSense system operating properly.
“System Not Available” — This message is displayed if the Side Distance Warning system is not available. The failed operation of the system might be due to the insufficient voltage from the battery or other failures on the electrical system. Contact an authorized dealer as soon as possible to have the electrical system checked.
ParkSense Usage Precautions
Some conditions may influence the performance of the Side Distance Warning system:
NOTE:
- Ensure that the front and rear fascia/bumper are free of snow, ice, mud, dirt and debris to keep the ParkSense system operating properly.
- Construction equipment, large trucks, and other vibrations could affect the performance of ParkSense.
- When you turn ParkSense off, the message to appear in the instrument cluster display will read “PARKSENSE OFF.” Furthermore, once you turn ParkSense off, it remains off until you turn it on again, even if you cycle the ignition key.
- 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.
- The presence of a tow hook without a trailer may interfere with the correct operation of the parking sensors. Before using the ParkSense system, it is recommended to remove the removable tow hook ball assembly and any attachments from the vehicle when it is not used for towing operations.
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.
