2017 JEEP CHEROKEE wheel torque

Shift Positions
For additional information on the appropriate use of each
4WD system mode position, see the information below:
NEUTRAL
This range disengages the driveline from the powertrain. It
is to be used for flat towing behind another vehicle. Refer
to “Recreational Towing” in “Starting And Operating” for
further information.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the power transfer unit in the
NEUTRAL (N) position without first fully engaging
the parking brake. The NEUTRAL (N) position disen-
gages both the front and rear driveshafts from the
powertrain and will allow the vehicle to roll, even if
the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.
4WD LOW
This range is for low speed four-wheel drive. It provides an
additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose, slip-
pery road surfaces only. Do not exceed 25 mph (40 km/h).
NOTE:Refer to “Selec-Terrain – If Equipped” for further
information on the various positions and their intended
usages.
Shifting Procedures
Shifting Into 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition in the ON mode and the engine running, shift the
transmission into NEUTRAL, and push the “4WD LOW”
button once. The “4WD LOW” indicator light in the
instrument cluster will begin to flash and remain on solid
when the shift is complete.
280 STARTING AND OPERATING

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.

STARTING AND OPERATING 355

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 “armed” 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 the left thin line turn solid
white. 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.
Lanes Sensed (White Lines/Green Indicator)
358 STARTING AND OPERATING

•When the LaneSense system senses the lane has been
approached and is in a lane departure situation, the left
thick lane line flashes from white to gray, the left thin
line remains solid white and 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.

STARTING AND OPERATING 361

•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.).
Lane Approached (Flashing Yellow Thick Line, Solid
Yellow Thin Line/Flashing Yellow Indicator)
362 STARTING AND OPERATING

Traction Downhill
Shift the transmission into a low gear and the 4WD System
to 4WD LOW range or Select Hill Descent Control if
equipped (refer toSafety Featuresin the “Safety” section
for further information). Let the vehicle go slowly down
the hill with all four wheels turning against engine com-
pression drag. This will permit you to control the vehicle
speed and direction.
When descending mountains or hills, repeated braking can
cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmission
whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage.
• Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required. •
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 braking system
may cause excessive wear or unpredictable braking
performance. Full braking power may not be available
to prevent a collision. If you have been operating your
vehicle in dirty conditions, inspect and clean the
braking components as soon as possible.
• Impacted material can cause wheel imbalance. Freeing
the wheels of impacted material will likely rectify im-
balance condition.
388 STARTING AND OPERATING

9. Install the wheel bolts with the threaded end of thewheel bolt toward the wheel. Lightly tighten the wheel
bolts.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.
10. Lower the vehicle to the ground by turning the jack handle counterclockwise.
11. Finish tightening the wheel bolts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the wheel bolts in a star pattern until
each wheel bolt has been tightened twice. Refer to
“Torque Specifications” in “Technical Specifications”
for the proper lug bolt torque. If in doubt about the
correct tightness, have them checked with a torque
wrench by your authorized dealer or at a service
station. 12. Securely stow the jack, tools, chocks and flat tire.
