2015 JEEP CHEROKEE transmission fluid

5. LaneSense — If Equipped
The LaneSense system provides the driver with
visual and steering torque warnings when the
vehicle starts to drift out of its lane uninten-
tionally without the use of a turn signal.
•When the LaneSense system is ON and ready the
lane lines and LaneSense indicator are the color gray.
•When the LaneSense system is armed, the lane lines
change to white and the LaneSense indicator
changes to green.
•When the LaneSense system senses a lane cross
situation, the approaching lane line and the La-
neSense indicator change from white to yellow.
For further information, refer to “Lanesense — If
Equipped” in “Understanding The Features Of Your
Vehicle”.
6. Fuel Gauge
Fuel Gauge displays the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
7. 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.
8. Rear Axle Lock Indicator — If Equipped
This light indicates when the rear axle lock has
been activated.
9. Reconfigurable Yellow 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 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.
•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”.

•Service Adaptive Cruise Control Telltale
This light will turn on when a ACC is not
operating and needs service. For further infor-
mation, refer to “Adaptive Cruise Control
(ACC)” in “Understanding The Features Of
Your Vehicle”.
•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.
•Transmission Over Temperature Telltale — If
Equipped
This telltale indicates that the transmission
fluid temperature is running hot. This may
occur with severe usage, such as trailer towing.
If this telltale turns on, safely pull over and
stop the vehicle. Then, shift the transmission into NEU-
TRAL and run the engine at idle or faster until the light
turns off.
•Service 4WD Telltale
If the light stays on or comes on during driv-
ing, it means that the 4WD system is not
functioning properly and that service is re-
quired. We recommend you drive to the near-
est service center and have the vehicle serviced
immediately.
•Diesel Wait To Start Telltale — If Equipped
The “Wait To Start” telltale will illuminate for
approximately two seconds when the ignition is
turned to the RUN position. It’s duration may be longer
based on colder operating conditions. Vehicle will not
initiate start until telltale is out. Refer to “Starting Proce-
dures” in “Starting and Operating” for further
information.

•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 the transmission temperature exceeds normal operat-
ing limits, the transmission controller may modify the
transmission shift schedule, reduce engine torque,
and/or expand the range of torque converter clutch
engagement. This is done to prevent transmission dam-
age due to overheating.
If the transmission becomes extremely hot, the “Trans-
mission Temperature Warning Light” may illuminate and
the transmission may operate differently until the trans-
mission cools down.
During cold temperatures, transmission operation may
be modified depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch, and shifts into 8th or 9th gear, are
inhibited until the transmission fluid is warm (refer to the
“Note” under “Torque Converter Clutch” in this section).
Normal operation will resume once the transmission
temperature has risen to a suitable level.
SPORT — IF EQUIPPED
This mode alters the transmission’s automatic shift
schedule for sportier driving. Upshift speeds are in-
creased to make full use of available engine power.
SPORT mode is activated using the rotary switch on the
center console. Refer to#Selec-Terrain#in this section for
further information.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in fourth gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will continue

STARTING AND OPERATING 491

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.

494 STARTING AND OPERATING

Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Trans-
fer Unit and Rear Drive Module) to assure they have not
been contaminated. Contaminated fluids and lubricants
(milky, foamy in appearance) should be flushed/changed
as soon as possible to prevent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the 4WD system to the appropriate terrain
mode, using 4WD LOW if necessary. Refer to “Four-
Wheel Drive Operation” in “Starting and Operating” for
further information. Do not shift to a lower gear than
necessary to maintain headway. Over-revving the engine
can spin the wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill,shift the transmission to a
lower gear and shift the 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
If you stall or begin to lose headwaywhile climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine and
shift to REVERSE. Back slowly down the hill allowing the
compression braking of the engine to help regulate your
speed. If the brakes are required to control vehicle speed,
apply them lightly and avoid locking or skidding the
tires.
