ESP JEEP GRAND CHEROKEE 2023 Owner's Manual

STARTING AND OPERATING153
The driver can override ADA at any time by
braking, accelerating, or steering the vehicle.
Just like ACC, ADA will maintain a set speed as long
as the set distance between your vehicle and the
vehicle in front is maintained. ADA will also keep
your vehicle centered between the lane lines, and
monitor for other vehicles in adjacent lanes by
utilizing the Blind Spot Monitoring sensors.
Two types of Active Driving Assist systems are
available:
Base ADA system
Hands-Free ADA system
Base Active Driving Assist System — If Equipped
The Base ADA system uses sensors within the
steering wheel to measure driver attentiveness,
and requires that the driver have their hands on
the steering wheel at all times.
The system will generally aim to keep the vehicle
centered in the lane, but when the driver turns the
steering wheel (e.g. to move farther away from a
large vehicle in an adjacent lane) the system will
reduce its control and enter "co-steering" mode.
While in co-steering mode, the system will provide
reduced assistance and allow the driver to control
the path of the vehicle. Once the driver stops
providing input to the steering wheel, the system
will require a few seconds to fully resume lane
centering assistance, especially during curves. Hands-Free Active Driving Assist System —
If Equipped
The Hands-Free ADA system uses sensors within
the steering wheel and a driver monitoring camera
located on top of the steering column to monitor
driver attentiveness. The Hands-Free ADA system
allows the driver to remove their hands from the
steering wheel when engaged, but requires that
the driver continue to pay attention to the road.
The Hands-Free ADA system will also change lanes
when a turn signal is activated if the adjacent lane
in the direction indicated is clear of another
vehicle, and lane markings are detected (noted by
a dashed line in the direction of the available lane
change). The system uses sensors, including Blind
Spot Monitoring (BSM) sensors, to determine if a
lane change is possible. If the assisted lane
change is in progress, a green arrow will appear. If
a lane change is requested but the direction
indicated is not possible, a yellow arrow will
appear. Once conditions are clear, the arrow will
turn green and the assisted lane change will begin.
Additionally, Hands-Free ADA will slow the vehicle
down when approaching and going through sharp
curves.

Assisted Lane Change (Green Left Arrow)

Extended Auto Resume
If equipped with Hands-Free ADA and the system
brings your vehicle to a stop while following the
vehicle ahead, your vehicle will automatically
resume driving without driver input when the path
in front of the vehicle is clear and the driver is
attentive. The path in front of the vehicle is
determined to be clear based on the forward facing
camera, front radars, and front ultrasonic sensors.WARNING!
The driver is always responsible for determining
if a lane change is safe. Failure to follow this
warning can result in a collision and death or
serious personal injury.

154STARTING AND OPERATING
(Continued)
If the vehicle in front does not start moving after
10 minutes, the Electric Park Brake (EPB) will be
applied and the system will cancel.
NOTE:
The Hands-Free Active Driving Assist system is
only available on approved compatible road
-
ways. Please consult the Jeep® website for
further details on compatible roadways.
The Hands-Free Active Driving Assist system
requires an active subscription through the
Jeep® Connect (Uconnect Connected Services)
package. If the ADA on/off button is pushed
without an active subscription, the instrument
cluster display will show the message “Active
Driving Assist Unavailable Update Subscrip -
tion”. Refer to the Uconnect Owner’s Manual
Supplement for further information.
If previously disabled, activating the Hands-Free
Active Driving Assist system will also activate
the Forward Collision Warning and Pedestrian
Emergency Braking systems Ú page 261.
If the vehicle is equipped with the Jeep®
Connect (Uconnect Connected Services)
package, additional data may be collected
through the Jeep® Connect (Uconnect
Connected Services) system. This includes
information about the vehicle’s operation, a
collision involving the vehicle, the use of the
vehicle and its features, and in certain situa -tions, the location and approximate GPS speed
of the vehicle. Refer to the Uconnect Owner’s
Manual Supplement for Terms and Conditions
and Privacy Statements.
The driver monitoring camera may record
images of the driver during certain crash, or
near crash-like situations. To retrieve the
images recorded by the camera, special equip
-
ment is required and access to the vehicle or
the camera is needed.
Vehicle data may be read from the Hands-Free
ADA system with special equipment and access
to the vehicle or the Event Data Recorder (EDR).
WARNING!
The Active Driving Assist (ADA) system is a
convenience system. It is not a substitute for
active driver involvement. It is always the driver’s
responsibility to be attentive of road traffic,
weather conditions, vehicle speed, distance to
the vehicle ahead, position in the lane compared
to other vehicles, and brake operation to ensure
safe operation of the vehicle under all road
conditions. Your complete attention is always
required while driving to maintain safe control of
your vehicle. Failure to follow these warnings can
result in a collision and death or serious
personal injury.
Some states and local laws may require hands
to be kept on the steering wheel at all times. For
vehicles equipped with the Hands-Free ADA
system, ONLY remove your hands from the
steering wheel if the Hands-Free system is
engaged, it is safe to do so, and it is permitted by
state and local laws.
You should turn off the Active Driving Assist
systems:
When driving in complex driving situations
(e.g. urban environments, construction zones,
etc.), adverse weather or low visibility condi -
tions (e.g. rain, snow, fog, sleet, dust), or
adverse road conditions (e.g. heavy traffic,
worn or missing lane markings, etc.).
When entering a highway on-ramp or exiting
an off-ramp.
When driving on roads that are icy, snow
covered, or slippery.
When driving during difficult or uncertain
conditions.

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
ParkSense 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 Program -
mable Features section of the Uconnect system.
ParkSense will retain its last known configura -
tion 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.

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
P
RECAUTIONS
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.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of
ParkSense.
When you turn ParkSense off, the instrument
cluster will display “PARKSENSE OFF.” Further -
more, 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 recom -
mended 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.

23_WL_OM_EN_USC_t.book Page 164

166STARTING AND OPERATING
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.

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, providing audible/visual
instructions, and controlling the steering wheel.
The ParkSense Active Park Assist system is
defined as “semi-automatic” since the driver
maintains control of the accelerator, gear selector
and brakes. Depending on the driver's parking
maneuver selection, the ParkSense Active Park
Assist system is capable of maneuvering a vehicle
into a parallel or a perpendicular parking space on
either side (i.e., driver side or passenger side).
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 recom
-
mended 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 recom -
mended that the driver looks over his/her
shoulder when using ParkSense.

23_WL_OM_EN_USC_t.book Page 166

STARTING AND OPERATING167
NOTE:
The driver is always responsible for controlling
the vehicle, responsible for any surrounding
objects, and must intervene as required.
The system is designed 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.
environmental conditions such as heavy rain,
snow, etc., or if searching for a parking space
that has surfaces that will absorb the ultrasonic
sensor waves).
New vehicles from the dealership must have at
least 30 miles (48 km) accumulated before the
ParkSense Active Park Assist system is fully cali -
brated 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 differ -
ences such as over or under inflated tires and
new tires.
ENABLING AND DISABLING THE
P
ARKSENSE ACTIVE PARK ASSIST

S
PACE ASSISTANCE OPERATION
When the ParkSense Active Park Assist system is
enabled, you can select between Parallel,
Perpendicular, and Parallel Park Exit maneuvers in
the Uconnect system.
Choose Parking Maneuver Below

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 parking
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).
When searching 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 (e.g., if passing multiple available
parking spaces, the system will only indicate the
last detected parking space for the maneuver).
While the vehicle is in DRIVE, there will be a full
screen image in the Uconnect display. If the
driver shifts to REVERSE while searching for a
parking space, a camera image will appear in
the Uconnect display with a “Shift To Drive”
message.
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 perpendicular or parallel parking sequence
(depending on the type of maneuver being
performed).

23_WL_OM_EN_USC_t.book Page 168

STARTING AND OPERATING169
Once active steering begins, a camera image will
display in the Uconnect display with prompts that
will display for the duration of the maneuver.

Parking Space Found — Keep Moving Forward

Once the vehicle is in position, you will be
instructed to stop the vehicle’s movement and
remove your hands from the steering wheel. When
the vehicle comes to a standstill (your hands still
removed from the steering wheel), you will be
instructed to place the gear selector into the
REVERSE position.
Shift To Reverse — Parallel Parking Space
Shift To Reverse — Perpendicular Parking Space
The system may then instruct the driver to wait for
steering to complete before then instructing to
check the vehicle’s surroundings, and move
backward.
Several more gear shifts (DRIVE and REVERSE)
while keeping hands off of the steering wheel will
be instructed to the driver while checking the
vehicle’s surroundings before completing the
parking maneuver.
When the vehicle is in the parking position, the
maneuver is complete and the driver will be
instructed to check the vehicle's parking position,
then shift the vehicle into PARK. The message
“Active ParkSense Complete - Check Parking
Position” will be displayed momentarily.
NOTE:
It is the driver's responsibility to use the brake
and stop the vehicle. The driver should check
their surroundings and be prepared to stop the
vehicle either when instructed to, or when driver
intervention is required.
It is the driver’s responsibility to use the brake
and accelerator during the semi-automatic
parking maneuver.

23_WL_OM_EN_USC_t.book Page 169

170STARTING AND OPERATING
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 ParkSense Active Park Assist system will
allow a maximum of eight shifts between DRIVE
and REVERSE. If the maneuver cannot be
completed within eight shifts, the system will
cancel and the instrument cluster display will
instruct the driver to complete the maneuver
manually.
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 completing 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.EXITING THE PARKING SPACE
NOTE:The function does not work for exiting a perpen -
dicular parking space, but only exiting parallel
parking spaces.
Activation
To activate this function, push the Active
ParkSense switch once. After selection, the system
activates and warns the driver on the instrument
cluster display about the operations that have to
be carried out to perform the maneuver correctly.
WARNING!
Drivers must be careful when performing
parallel or perpendicular parking maneuvers
even when using the ParkSense Active Park
Assist system. Always check carefully behind
and in front of your vehicle, look behind and in
front of you, and be sure to check for pedes -
trians, animals, other vehicles, obstructions,
and blind spots before backing up and moving
forward. 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 the ParkSense Active Park Assist
system, it is strongly recommended that the
ball mount and hitch ball assembly be discon -
nected 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!
The ParkSense Active Park Assist system 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
the ParkSense Active Park Assist system 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 the ParkSense Active Park Assist
system.
