2020 JEEP GRAND CHEROKEE turn signal

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.).
