Jeep Grand Cherokee (2019 year). Instruction

Towing A Trailer

Towing a trailer is not advised when using ACC.

Offset Driving

ACC may not detect a vehicle in the same lane that is offset
from your direct line of travel, or a vehicle merging in from
a side lane. There may not be sufficient distance to the
vehicle ahead. The offset vehicle may move in and out of
the line of travel, which can cause your vehicle to brake or
accelerate unexpectedly.

Turns And Bends

When driving on a curve with ACC engaged, the system
may decrease the vehicle speed and acceleration for stabil-
ity reasons, with no target vehicle detected. Once the
vehicle is out of the curve the system will resume your
original set speed. This is a part of normal ACC system
functionality.

NOTE:

On tight turns ACC performance may be limited.

STARTING AND OPERATING

Using ACC On Hills

When driving on hills, ACC may not detect a vehicle in
your lane. Depending on the speed, vehicle load, traffic
conditions, and the steepness of the hills, ACC perfor-
mance may be limited.

Lane Changing

ACC may not detect a vehicle until it is completely in the
lane in which you are traveling. In the illustration shown,
ACC has not yet detected the vehicle changing lanes and it
may not detect the vehicle until it’s too late for the ACC
system to take action. ACC may not detect a vehicle until it
is completely in the lane. There may not be sufficient
distance to the lane-changing vehicle. Always be attentive
and ready to apply the brakes if necessary.

STARTING AND OPERATING

309

Narrow Vehicles

Some narrow vehicles traveling near the outer edges of the
lane or edging into the lane are not detected until they have
moved fully into the lane. There may not be sufficient
distance to the vehicle ahead.

Stationary Objects And Vehicles

ACC does not react to stationary objects and stationary
vehicles. For example, ACC will not react in situations
where the vehicle you are following exits your lane and the
vehicle ahead is stopped in your lane. Always be attentive
and ready to apply the brakes if necessary.

STARTING AND OPERATING

NOTE:

Changes or modifications not expressly approved

by the party responsible for compliance could void the
user’s authority to operate the equipment.

Normal (Fixed Speed) Cruise Control Mode

In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Cruise Control mode is available for cruising
at fixed speeds. The Normal (Fixed Speed) Cruise Control
mode is designed to maintain a set cruising speed without
requiring the driver to operate the accelerator. Cruise
Control can only be operated if the vehicle speed is above
20 mph (32 km/h).

To change between the different control modes, push the
Adaptive Cruise Control (ACC) on/off button which turns
the ACC and the Normal (Fixed Speed) Cruise Control off.
Pushing the Normal (Fixed Speed) Cruise Control on/off
button will result in turning on (changing to) the Normal
(Fixed Speed) Cruise Control mode.

WARNING!

In the Normal (Fixed Speed) Cruise Control mode, the
system will not react to vehicles ahead. In addition, the
proximity warning does not activate and no alarm will
sound even if you are too close to the vehicle ahead
since neither the presence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected. Be sure to main-
tain a safe distance between your vehicle and the
vehicle ahead. Always be aware which mode is se-
lected.

To Set A Desired Speed

Turn the Normal (Fixed Speed) Cruise Control
on. When the vehicle has reached the desired
speed, push the SET (+) or SET (-) button and
release. Release the accelerator and the vehicle

will operate at the selected speed. Once a speed has been
set a message “CRUISE CONTROL SET TO MPH (km/h)”
will appear indicating what speed was set. This light will
turn on when the system is turned on via the on/off
control. It turns green when the cruise control is set.

PARKSENSE REAR PARK ASSIST — IF EQUIPPED

The ParkSense Rear Park Assist system provides visual and
audible indications of the distance between the rear fascia
and a detected obstacle when backing up, e.g. during a
parking maneuver. If your vehicle is equipped with an
automatic transmission, the vehicle brakes may be auto-
matically applied and released when performing a reverse
parking maneuver if the system detects a possible collision
with an obstacle.

STARTING AND OPERATING

313

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 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” in this
section for limitations of this system and recommenda-
tions.

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. If ParkSense is enabled at this gear selector
position, the system will remain active until the vehicle
speed is increased to approximately 7 mph (11 km/h) or

314

STARTING AND OPERATING

above. When in REVERSE and above the system’s operat-
ing speed, a warning will appear within the instrument
cluster display indicating the vehicle speed is too fast. The
system will become active again if the vehicle speed is
decreased to speeds less than approximately 6 mph
(9 km/h).

ParkSense Sensors

The four ParkSense sensors, 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 12 inches (30 cm) up to 79 inches (200
cm) from the rear fascia/bumper in the horizontal direc-
tion, depending on the location, type and orientation of the
obstacle.

ParkSense Display

The ParkSense display is always shown in the instrument
cluster display as long as the vehicle is in REVERSE.

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.

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.

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.

STARTING AND OPERATING

319

Service The ParkSense Rear Park Assist System

During vehicle start up, when the ParkSense Rear Park
Assist System has detected a faulted condition, the instru-
ment cluster will actuate a single chime, once per ignition
cycle, and it will display the “PARKSENSE UNAVAIL-
ABLE WIPE REAR SENSORS” or the “PARKSENSE UN-
AVAILABLE SERVICE REQUIRED” message. Refer to “In-
strument Cluster Display”. When the gear selector is
moved to REVERSE and the system has detected a faulted
condition, the instrument cluster display will display the

⬙PARKSENSE UNAVAILABLE WIPE REAR SENSORS⬙ or

⬙PARKSENSE UNAVAILABLE SERVICE REQUIRED⬙ mes-
sage for as long as the vehicle is in REVERSE. Under this
condition, ParkSense will not operate.

If “PARKSENSE UNAVAILABLE WIPE REAR SENSORS”
appears in the instrument cluster display make sure the
outer surface and the underside of the rear fascia/bumper
is clean and clear of snow, ice, mud, dirt or other obstruc-
tion and then cycle the ignition. If the message continues to
appear, see an authorized dealer.

If “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
appears in the instrument cluster display, see an autho-
rized 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. 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
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 display will display “PARKSENSE OFF” mes-
sage 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.

320

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 the fascia/bumper, or it could provide a
false indication that an obstacle is behind 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 display.

• ParkSense should be disabled when the liftgate is in the

open position and the vehicle is in REVERSE. An open
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

321

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 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.

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 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).

ParkSense Sensors

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
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.
