2017 JEEP GRAND CHEROKEE wheel torque

WARNING!(Continued)
continue to pay attention to your surroundings. Fail-
ure 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 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, depend-
ing 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.
(Continued)
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
recommended 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 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 a visual
warning 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 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 “Lane Sense On” message is
shown in the instrument cluster display.

been detected and the system is ready to provide visual
warnings in the instrument cluster display if an unin-
tentional lane departure occurs.
• 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 indicator
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 detected. The LaneSense indicator
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.
Lane Approached (Flashing Yellow Thick Line, Solid
Yellow Thin Line/Flashing Yellow Indicator)
Lanes Sensed (White Lines/Green Indicator)
362 STARTING AND OPERATING

The LaneSense indicator changes from solid green to
solid 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.
• 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 indicator changes from solid yellow to flashing 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 “Multime-
dia” 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 warnings.
• The system will not apply torque to the steering wheel
whenever a safety system engages. (anti-lock brakes,
traction control system, electronic stability control, for-
ward collision warning, etc.).
PARKVIEW REAR BACK UP CAMERA — IF
EQUIPPED
Your vehicle may be equipped with the ParkView Rear
Back Up Camera that allows you to see an on-screen image
of the rear surroundings of your vehicle whenever the gear
selector is put into REVERSE. The image will be displayed
on the Navigation/Multimedia radio display screen along
with a caution note to “check entire surroundings” across the top of the screen. After five seconds this note will
disappear. The ParkView camera is located on the rear of
the vehicle above the rear License plate.
When the vehicle is shifted out of REVERSE (with camera
delay turned off), the rear camera mode is exited and the
navigation or audio screen appears again.
When the vehicle is shifted out of REVERSE (with camera
delay turned on), the rear view image with dynamic grid
lines will be displayed for up to 10 seconds after shifting
out of REVERSE unless the forward vehicle speed exceeds
8 mph (13 km/h), the transmission is shifted into PARK or
the ignition is switched to the OFF position.
NOTE:
The ParkView Rear Back Up Camera has program-
mable modes of operation that may be selected through the
Uconnect System. Refer to “Uconnect Settings” in “Multi-
media” for further information.
When enabled, active guide lines are overlaid on the image
to illustrate the width of the vehicle and its projected
backup path based on the steering wheel position. A
dashed center line overlay indicates the center of the
vehicle to assist with parking or aligning to a hitch/
receiver. Different colored zones indicate the distance to the

•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.
