2015 JEEP CHEROKEE wheel torque

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 “Understanding Your Instrument Panel” 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,
forward collision warning, etc.).
PARKSENSE® REAR PARK ASSIST — IF
EQUIPPED
The ParkSense® Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to ParkSense® System
Usage Precautions 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® can be active only when the shift lever/gear
selector is in REVERSE. If ParkSense® is enabled at this
shift lever/gear selector position, the system will remain
active until the vehicle speed is increased to approxi-
mately 7 mph (11 km/h) or above. When in REVERSE
and above the system’s operating speed, a warning will
appear within the Electronic Vehicle Information Center

the vehicle in a high torque converter slip condition,
such as 4-wheel drive operation (e.g., snow plowing,
off- road operation). If this light comes on, stop the
vehicle and run the engine at idle or faster, with the
transmission in NEUTRAL until the light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illumi-
nated you could cause the fluid to boil over, come in
contact with hot engine or exhaust components and
cause a fire.

and rear wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide in-
creased torque at the wheels.
For further information on four-wheel drive operation
and proper use, refer to “Four-Wheel Drive Operation —
If Equipped” in “Starting And Operating”.
15. SERV 4WD Indicator Light — If Equipped
This light alerts the driver that the 4WD is in need of
service. If this light is illuminated, see your authorized
dealer as soon as possible.
16. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your

12. Amber Reconfigurable Telltale Display
•Transmission Temperature Warning Light
This light indicates that there is excessive
transmission fluid temperature that might
occur with severe usage such as trailer
towing. It may also occur when operating
the vehicle in a high torque converter slip condition,
such as 4-wheel-drive operation (e.g., snow plowing,
off- road operation). If this light comes on, stop the
vehicle and run the engine at idle or faster, with the
transmission in NEUTRAL until the light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illumi-
nated you could cause the fluid to boil over, come in
contact with hot engine or exhaust components and
cause a fire.
•Low Fuel Telltale
When the fuel level reaches approximately 3.0
gal (11.0 L) this light will turn on, and remain
on until fuel is added.
•Rear Axle Lock Indicator — If Equipped
This light indicates when the rear axle lock
has been activated.

•Low Coolant Level Indicator
This telltale will turn on to indicate the
vehicle coolant level is low.
•Windshield Washer Fluid Low Indicator
This telltale will turn on to indicate the
windshield washer fluid is low.
•4WD LOW Indicator Light — If Equipped
This light alerts the driver that the vehicle is in the
four-wheel drive LOW mode. The front and rear
driveshafts are mechanically locked together forcing
the front and rear wheels to rotate at the same speed.
Low range provides a greater gear reduction ratio to
provide increased torque at the wheels.
For further information on four-wheel drive opera-
tion and proper use, refer to “Four-Wheel Drive
Operation — If Equipped” in “Starting And
Operating”.
•SERV 4WD Indicator Light — If Equipped
This light alerts the driver that the 4WD is in need of
service. If this light is illuminated, see your autho-
rized dealer as soon as possible.
•Adaptive Cruise Control (ACC) Malfunction
This light will turn on when a ACC is not
operating and needs service. For further
information, refer to “Adaptive Cruise
Control (ACC)” in “Understanding The
Features Of Your Vehicle”.

Moving the shift lever to the ERS position (beside
DRIVE) will activate ERS mode, display the current gear
in the instrument cluster, and maintain that gear as the
top available gear. Once in ERS mode, moving the shift
lever forward (-) or rearward (+) will change the top
available gear.
To exit ERS mode, simply return the shift lever to the
DRIVE position.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
NOTE:To select the proper gear position for maximum
deceleration (engine braking), move the shift lever into
the ERS position, then simply press and hold it forward
(-). The transmission will shift to the range from which
the vehicle can best be slowed down.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
some accelerations, the clutch automatically disengages.

STARTING AND OPERATING 493

NOTE:The torque converter clutch will not engage until
the transmission fluid is warm (usually after 1 to 3 miles
[2 to 5 km] of driving). Because the engine speed is higher
when the torque converter clutch is not engaged, it may
seem as if the transmission is not shifting properly when
cold, this is normal. The torque converter clutch will
function normally once the transmission is sufficiently
warm.
FOUR-WHEEL DRIVE OPERATION
1-Speed Four-Wheel Drive (4X4) — If Equipped
This feature provides on-demand four-wheel drive (4X4).
The system is automatic with no driver inputs or addi-
tional driving skills required. Under normal driving
conditions, the front wheels provide most of the traction.
If the front wheels begin to lose traction, power is shifted
automatically to the rear wheels. The greater the front
wheel traction loss, the greater the power transfer to the
rear wheels.

Additionally, on dry pavement under heavy throttle
input (where one may have no wheel spin), torque will be
sent to the rear in a pre-emptive effort to improve vehicle
launch and performance characteristics.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the power transfer unit.
