Lanesense - If Equipped; Lanesense Operation - Jeep Grand Cherokee 2020 Owner's Manual

250 STARTING AND OPERATING
WARNING! (Continued)
Before using the ParkSense Active Park

Assist system, 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!
The ParkSense Active Park Assist system is

only a parking aid and it is unable to recog-
nize every obstacle, including small obsta-
cles. 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.
CAUTION! (Continued)
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 recom-
mended that the driver looks over his/her
shoulder when using the ParkSense Active
Park Assist system.
LANESENSE — IF EQUIPPED

LaneSense Operation

The LaneSense system is operational at speeds
above 37 mph (60 km/h) and below 112 mph
(180 km/h). The LaneSense system uses a
forward looking camera to detect lane markings
and measure vehicle position within the lane
boundaries.
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 unintentionally drift out
(Continued)
of the lane, the LaneSense 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 provide 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.
