2019 Jeep Grand Cherokee Owners Manual - PARKSENSE FRONT AND REAR PARK ASSIST — IF EQUIPPED

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. If your vehicle is equipped with an automatic transmission, the vehicle brakes may be automatically applied and released when performing a reverse parking maneuver if the sys- tem detects a possible collision with an obstacle.

NOTE:

The driver can override the automatic braking function by pressing the gas pedal, turning ParkSense off via ParkSense switch, or changing the gear while the auto- matic brakes are being applied.

Automatic brakes are not available if the vehicle is in 4LO.

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 ob- stacles when backing up in REVERSE gear.

NOTE:

The driver is always responsible for controlling the vehicle.

The system is provided to assist the driver and not to substitute the driver.

the vehicle speed is decreased to speeds less than approxi- mately 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).

The four ParkSense sensors (or six, if equipped with Active Park Assist), 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 6

The driver must stay in full control of the vehicle’s acceleration and braking and is responsible for the vehicle’s movements.

Refer to “ParkSense System Usage Precautions” for limita- tions 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. The system will become active again if

12 inches (30 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.

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.

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.

Park Assist Ready

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.

Single 1/2 Second Tone

NOTE: ParkSense will reduce the volume of the radio, if on, when the system is sounding an audio tone.

Front Park Assist Audible Alerts

ParkSense will turn off the Front Park Assist audible alert (chime) after approximately 3 seconds when an obstacle has been detected, the vehicle is stationary, and brake pedal is applied.

Adjustable Chime Volume Settings

Front and Rear chime volume settings can be selected from the Uconnect System. Refer to "Uconnect Settings” in “Multimedia” for further information.

The chime volume settings include low, medium, and high. The factory default volume setting is medium.

ParkSense will retain its last known configuration state through ignition cycles.

The ParkSense Warning screen will only be displayed if Sound and Display is selected from the Customer Pro- grammable Features section of the Uconnect System. Refer to "Uconnect Settings” in “Multimedia” for further infor- mation.

The ParkSense Warning screen is located within the instru- ment cluster display. It provides visual warnings to indi- cate the distance between the rear fascia/bumper and/or front fascia/bumper and the detected obstacle. Refer to “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” for further information.

ParkSense can be enabled and disabled with the ParkSense

When the ParkSense switch is pushed to disable the system, the instrument cluster will display the “PARKSENSE OFF” message for approxi- mately five seconds. When the gear selector is

moved to REVERSE and the system is disabled, the instru- ment cluster display will display the “PARKSENSE OFF” message for as long as the vehicle is in REVERSE.

Refer to “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” for further information.

NOTE: When ParkSense is disabled and the gear selector is moved to the DRIVE position, no warning message will be displayed.

REQUIRED" message 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 SEN- SORS", "PARKSENSE UNAVAILABLE WIPE FRONT SEN- SORS" or "PARKSENSE UNAVAILABLE SERVICE RE-

QUIRED" pop up message for five seconds. After five seconds, a vehicle graphic will be displayed with "UN- AVAILABLE" 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 function- ing 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 dis- played for as long as the vehicle is in REVERSE.

Refer to “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” for further information.

If "PARKSENSE UNAVAILABLE WIPE REAR SENSORS" or "PARKSENSE UNAVAILABLE WIPE FRONT SEN-

SORS" 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 your authorized dealer.

If the "PARKSENSE UNAVAILABLE SERVICE RE-

QUIRED" message appears in the instrument cluster dis- play, see your authorized dealer.

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.

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. 6

are placed within 12 inches (30 cm) from 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.
