Jeep Grand Cherokee (2019 year). Instruction

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.

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.

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.

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 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.

330

STARTING AND OPERATING

• 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) 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.

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 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.

STARTING AND OPERATING

331

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.

PARKSENSE ACTIVE PARK ASSIST SYSTEM — IF
EQUIPPED

The ParkSense Active Park Assist system is intended to
assist the driver during parallel and perpendicular parking
maneuvers by identifying a proper parking space, provid-
ing audible/visual instructions, and controlling the steer-
ing wheel. The ParkSense Active Park Assist system is
defined as “semi-automatic” since the driver maintains

control of the accelerator, gear selector and brakes. De-
pending on the driver’s parking maneuver selection, the
ParkSense Active Park Assist system is capable of maneu-
vering a vehicle into a parallel or a perpendicular parking
space on either side (i.e., driver side or passenger side).

NOTE:
• The driver is always responsible for controlling the

vehicle, responsible for any surrounding objects, and
must intervene as required.

• The system is provided to assist the driver and not to

substitute the driver.

• During a semi-automatic maneuver, if the driver touches

the steering wheel after being instructed to remove their
hands from the steering wheel, the system will cancel,
and the driver will be required to manually complete the
parking maneuver.

• The system may not work in all conditions (e.g. envi-

ronmental conditions such as heavy rain, snow, etc., or if
searching for a parking space that has surfaces that will
absorb the ultrasonic sensor waves).

332

STARTING AND OPERATING

• New vehicles from the dealership must have at least 30

miles (48 km) accumulated before the ParkSense Active
Park Assist system is fully calibrated and performs
accurately. This is due to the system’s dynamic vehicle
calibration to improve the performance of the feature.
The system will also continuously perform the dynamic
vehicle calibration to account for differences such as
over or under inflated tires and new tires.

Enabling And Disabling The ParkSense Active Park
Assist System

The ParkSense Active Park Assist system can be
enabled and disabled with the ParkSense Active
Park Assist switch, located on the switch panel
below the Uconnect display.

To enable the ParkSense Active Park Assist system, push
the ParkSense Active Park Assist switch once (LED turns
on).

To disable the ParkSense Active Park Assist system, push
the ParkSense Active Park Assist switch again (LED turns
off).

The ParkSense Active Park Assist system will turn off
automatically for any of the following conditions:
• The parking maneuver is completed.
• Vehicle speed greater than 18 mph (30 km/h) when

searching for a parking space.

• Vehicle speed greater than 5 mph (7 km/h) during active

steering guidance into the parking space.

• Touching the steering wheel during active steering guid-

ance into the parking space.

• Pushing the ParkSense Front and Rear Park Assist

switch.

• Driver’s door is opened.
• Rear liftgate is opened.
• Electronic Stability Control/Anti-lock Braking System

intervention.

• The ParkSense Active Park Assist system will allow a

maximum of six shifts between DRIVE and REVERSE. If
the maneuver cannot be completed within six shifts, the
system will cancel and the instrument cluster display
will instruct the driver to complete the maneuver manu-
ally.

STARTING AND OPERATING

333

The ParkSense Active Park Assist system will only operate
and search for a parking space when the following condi-
tions are present:
• Gear position is in DRIVE.
• Ignition is in the RUN position.
• ParkSense Active Park Assist switch is activated.
• Driver’s door is closed.
• Rear liftgate is closed.
• Vehicle speed is less than 15 mph (25 km/h).

NOTE:

If the vehicle is driven above approximately

15 mph (25 km/h), the instrument cluster display will
instruct the driver to slow down. If the vehicle is driven
above approximately 18 mph (30 km/h), the system will
cancel. The driver must then reactivate the system by
pushing the ParkSense Active Park Assist switch.
• The outer surface and the underside of the front and rear

fascias/bumpers are clean and clear of snow, ice, mud,
dirt or other obstruction.

When pushed, the LED on the ParkSense Active Park
Assist switch will blink momentarily, and then the LED
will turn off if any of the above conditions are not present.

Parallel Parking Space Assistance Operation/
Display

When the ParkSense Active Park Assist system is enabled
the “Active ParkSense Searching - Press OK to Switch to
Perpendicular” message will appear in the instrument
cluster display. You may switch to perpendicular parking if
you desire. Push the OK button on the left side steering
wheel switch to change your parking space setting.

NOTE:
• When searching for a parking space, use the turn signal

indicator to select which side of the vehicle you want to
perform the parking maneuver. The ParkSense Active
Park Assist system will automatically search for a park-
ing space on the passenger’s side of the vehicle if the
turn signal is not activated.

• The driver needs to make sure that the selected parking

space for the maneuver remains free and clear of any
obstructions (e.g. pedestrians, bicycles, etc.).

• The driver is responsible to ensure that the selected

parking space is suitable for the maneuver and free/
clear of anything that may be overhanging or protruding
into the parking space (e.g., ladders, tailgates, etc. from
surrounding objects/vehicles).

334

STARTING AND OPERATING

• When seeking for a parking space, the driver should

drive as parallel or perpendicular (depending on the
type of maneuver) to other vehicles as possible.

• The feature will only indicate the last detected parking

space (example: if passing multiple available parking
spaces, the system will only indicate the last detected
parking space for the maneuver).

When an available parking space has been found, and the
vehicle is not in position, you will be instructed to move
forward to position the vehicle for a parallel parking
sequence.

STARTING AND OPERATING

335

When the driver places the gear selector into the REVERSE
position, the system may instruct the driver to wait for
steering to complete.

The system will then instruct the driver to check their
surroundings and move backward.

NOTE:
• It is the driver’s responsibility to use the brake and

accelerator during the semi-automatic parking maneu-
ver.

• When the system instructs the driver to remove their

hands from the steering wheel, the driver should check
their surroundings and begin to back up slowly.

• The system will cancel the maneuver if the vehicle speed

exceeds 5 mph (7 km/h) during active steering guidance
into the parking space. The system will provide a
warning to the driver at 3 mph (5 km/h) that tells them
to slow down. The driver is then responsible for com-
pleting the maneuver if the system is canceled.

• If the system is canceled during the maneuver for any

reason, the driver must take control of the vehicle.

When the vehicle has reached the end of its backward
movement, the system will instruct the driver to check
their surroundings and stop the vehicle’s movement.

NOTE:

It is the driver’s responsibility to use the brake and

stop the vehicle. The driver should check their surround-
ings and be prepared to stop the vehicle either when
instructed to, or when driver intervention is required.
