2021 JEEP GRAND CHEROKEE warning

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, ob-
structions, and blind spots before back-
ing 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
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
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, in-
cluding 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 de-
tected. 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 automatictransmission, the vehicle brakes may be au-
tomatically applied and released when per-
forming a reverse parking maneuver if the
system detects a possible collision with an
obstacle.
Refer to “ParkSense System Usage Precau-
tions” in “Starting And Operating” in your
Owner’s Manual for limitations 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 Sensors
The four ParkSense sensors (or six, if
equipped with Active Park Assist), located in
the rear fascia/bumper, monitor the area be-
hind the vehicle that is within the sensors’
field of view. The sensors can detect ob-
stacles 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.
179

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, depend-
ing on the location, type and orientation of
the obstacle.
When an object is detected within 79 inches
(200 cm) behind the rear bumper while the
vehicle is in REVERSE, a warning will appear
in the instrument cluster display. In addition
a chime will sound (when Sound and Display
is selected from the Customer Programmable
Features section of the Uconnect System
screen). As the vehicle moves closer to the
object, the chime rate will change from single
1/2 second tone (for rear only), to slow (for
rear only), to fast, to continuous.Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with
the ParkSense switch.
When the ParkSense switch is
pushed to disable the system, the
instrument cluster will display the
“PARKSENSE OFF” message for
approximately five seconds. When the gear
selector is moved to REVERSE and the sys-
tem is disabled, the instrument cluster dis-
play 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” in
your Owner’s Manual 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 ParkSenseswitch is pushed, and the system requires
service, the ParkSense switch LED will blink
momentarily, and then the LED will be on.
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 pas-
senger side).
STARTING AND OPERATING
180

When both lane markings are detected and
the driver unintentionally drifts out of the
lane (no turn signal applied), the LaneSense
system provides a haptic warning in the form
of torque applied to the steering wheel to
prompt the driver to remain within the lane
boundaries. If the driver continues to unin-
tentionally drift out of the lane, the Lane-
Sense system provides a visual warning
through the instrument cluster display to
prompt the driver to remain within the lane
boundaries.
The driver may manually override the haptic
warning by applying torque into the steering
wheel at any time.
When only a single lane marking is detected
and the driver unintentionally drifts across
the lane marking (no turn signal applied), the
LaneSense system provides visual warnings
through the instrument cluster display to
prompt the driver to remain within the lane.
When only a single lane marking is detected,
a haptic (torque) warning will not be
provided.NOTE:
When operating conditions have been met,
the LaneSense system will monitor if the
driver’s hands are on the steering wheel and
provides an audible warning to the driver
when the driver’s hands are not detected on
the steering wheel. The system will cancel if
the driver does not return their hands to the
wheel.
Turning LaneSense On Or Off
The default status of LaneSense is off. The
LED in LaneSense button will be illuminated
while the system is deactivated.
The LaneSense button is located
on the switch panel below the
Uconnect display.
To turn the LaneSense system
on, push the LaneSense button (LED turns
off). A “LaneSense On” message is shown in
the instrument cluster display.
To turn the LaneSense system off, push the
LaneSense button once (LED turns on).NOTE:
The LaneSense system will retain the last
system state on or off from the last ignition
cycle when the ignition is changed to the
ON/RUN position.
LaneSense Warning Message
The LaneSense system will indicate the cur-
rent lane drift condition through the instru-
ment cluster display.
Premium Instrument Cluster Display
When the LaneSense system is on; the lane
lines are gray when both of the lane bound-
aries have not been detected and the Lane-
Sense telltale
is solid white.
Left Lane Departure — Only Left Lane Detected
• When the LaneSense system is on, the
LaneSense telltale
is solid white when
only the left lane marking has been de-
tected and the system is ready to provide
visual warnings in the instrument cluster
display if an unintentional lane departure
occurs.
STARTING AND OPERATING
182

• When the LaneSense system senses the
lane has been approached and is in a lane
departure situation, the left thick lane line
flashes yellow (on/off), the left thin line
remains solid yellow and the LaneSense
telltale
changes from solid white to
flashing yellow.
NOTE:
The LaneSense system operates with the
similar behavior for a right lane departure
when only the right lane marking has been
detected.
Left Lane Departure — Both Lanes Detected
• When the LaneSense system is on, the lane
lines turn from gray to white to indicate that
both of the lane markings have been de-
tected. The LaneSense telltale
is solid
green when both lane markings have been
detected and the system is on to provide
visual warnings in the instrument cluster
display and a torque warning in the steering
wheel if an unintentional lane departure
occurs.• When the LaneSense system senses a lane
drift situation, the left thick lane line and
left thin line turn solid yellow. The Lane-
Sense telltale
changes from solid green
to solid yellow. At this time torque is ap-
plied to the steering wheel in the opposite
direction of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.
• When the LaneSense system senses the
lane has been approached and is in a lane
departure situation, the left thick lane line
flashes yellow (on/off) and the left thin line
remains solid yellow. The LaneSense tell-
tale
changes from solid yellow to flash-
ing yellow. At this time torque is applied to
the steering wheel in the opposite direction
of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.
NOTE:
The LaneSense system operates with the
similar behavior for a right lane departure.
Changing LaneSense Status
The LaneSense system has settings to adjust
the intensity of the torque warning and the
warning zone sensitivity (early/late) that you
can configure through the Uconnect system
screen. Refer to “Uconnect Settings” in
“Multimedia” in your Owner’s Manual for
further information.
NOTE:
• When enabled the system operates above
37 mph (60 km/h) and below 112 mph
(180 km/h).
• Use of the turn signal suppresses the warn-
ings.
• The system will not apply torque to the
steering wheel whenever a safety system
engages (anti-lock brakes, traction control
system, electronic stability control, forward
collision warning, etc.).

WARNING!
Drivers must be careful when backing up
even when using the ParkView Rear Back
Up Camera. Always check carefully behind
your vehicle, and be sure to check for
pedestrians, animals, other vehicles, ob-
structions, or blind spots before backing
up. You are responsible for the safety of
your surroundings and must continue to
pay attention while backing up. Failure to
do so can result in serious injury or death.
CAUTION!
• To avoid vehicle damage, ParkView
should only be used as a parking aid.
The ParkView camera is unable to view
every obstacle or object in your drive
path.
• To avoid vehicle damage, the vehicle
must be driven slowly when using
ParkView to be able to stop in time when
an obstacle is seen. It is recommended
that the driver look frequently over his/
her shoulder when using ParkView.NOTE:
If snow, ice, mud, or any foreign substance
builds up on the camera lens, clean the lens,
rinse with water, and dry with a soft cloth. Do
not cover the lens.
Rear Camera — Viewing At Speed
When the vehicle is in park, neutral or drive,
the Rear View Camera can be activated with
the “Rear View Camera” button in the Con-
trols menu. This feature allows the customer
to monitor the area directly behind the ve-
hicle (or trailer, if equipped) for up to ten
seconds while at speed. If the vehicle speed
remains below 8 mph (13 km/h), the Rear
View Camera image will be displayed con-
tinuously until deactivated via the “X” button
on the touchscreen.
