2023 JEEP GRAND CHEROKEE brake

150STARTING AND OPERATING
USING ACC ON HILLS
ACC performance may be limited 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 hill.

ACC Hill Example

LANE CHANGING
ACC may not detect a vehicle until it is completely
in the lane in which you are traveling. In the
following lane changing example, ACC has not yet
detected the vehicle changing lanes and it may not
detect the vehicle until it is 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.
Lane Changing Example

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.

Narrow Vehicle Example

STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects or
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. It will consider this stopped vehicle a
stationary object as it did not previously detect
movement from it. Always be attentive and ready
to apply the brakes if necessary.

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.
WARNING!

23_WL_OM_EN_USC_t.book Page 154

156STARTING AND OPERATING
NOTE:For the system to detect the driver’s hands on the
steering wheel, the wheel must be gripped on the
outside. Gripping the inside areas of the steering
wheel will not satisfy the hands-on condition to
engage the system.

status indicator lights will turn off, Active Lane
Management will return to its previous state,
and ACC will disable or remain engaged pending
system conditions.
Hands-Free System Deactivation (If Equipped)
In addition to the deactivation conditions listed
above, the Hands-Free ADA system will also
deactivate in the following situations:
The system initiates a Stop-In-Lane maneuver to
stop the vehicle due to driver inattentiveness.
The Stop-In-Lane maneuver can be overridden
by placing hands on the steering wheel and
applying the accelerator or brake pedal. Refer to
“Indications On The Display” in the next section
for further information.
The vehicle is not receiving a clear cellular
signal for an extended period of time.

or reduced functionality when one of the following
conditions occur:
The vehicle’s radar sensors and/or forward
facing camera is damaged, covered,
misaligned, or obstructed (e.g. by mud, ice,
snow, etc.)
WARNING!
Active Driving Assist is an SAE Level 2 Driver
Assist feature, requiring driver attention at all
times. To prevent serious injury or death:
Always remember that the Active Driving
Assist system is a convenience system that
cannot accurately detect all situations.
Complete attention is always required while
driving, even when using the Active Driving
Assist system.
Always remain alert and be ready to take
control of the vehicle in the event that the
Active Driving Assist system deactivates, or
otherwise lacks full functionality as described
further before and after this statement.
Always keep your hands on the steering wheel
when the Base Active Driving Assist system is
activated.
Always keep your eyes on the road when the
Hands-Free Active Driving Assist system is

Maintain a safe distance from other vehicles
and pay attention to traffic conditions.
Do not use a hand held device when either
Base, or Hands-Free Active Driving Assist
system is engaged.
Always pay attention to the road when the
Hands-Free Active Driving Assist system is
engaged. The Active Driving Assist system will
not steer to avoid safety hazards, construction
zones, objects, or road impediments. You
need to take control to steer and brake the
vehicle in such situations, and when merging
into traffic, exiting the highway, making a turn
for crossing traffic, or stopping for traffic
control devices.
Do not place any objects on the steering wheel
(e.g. steering wheel covers) which could inter -
fere with the hand detection sensors.
WARNING!

23_WL_OM_EN_USC_t.book Page 158

STARTING AND OPERATING159
If the suspension alignment is not correct, if the
vehicle is modified (e.g. lifting or lowering the
suspension, installing different sized wheels or
tires) or if there has been damage due to road
hazards
Driving near highway toll booths
NOTE:If damage to the windshield occurs, have the wind -
shield replaced by an authorized dealer as soon as
possible.
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.

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 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.
