2015 JEEP WRANGLER transmission fluid

Vehicle Odometer Messages
When the appropriate conditions exist, the following
odometer messages will display:
ECO.....................Fuel Saver Indicator
door.............................Door Ajar
gATE........................Swing Gate Ajar
LoW tirE....................LowTirePressure
HOTOIL...........Transmission Oil Temperature
Above Normal Limits
gASCAP......................Fuel Cap Fault
noFUSE..........................Fuse Fault
CHAngE OIL..............OilChange Required
NOTE:If the vehicle is equipped with the optional
Electronic Vehicle Information Center (EVIC) in the in-
strument cluster, all the messages will only be displayed
in the EVIC display. For additional information, refer to
“Electronic Vehicle Information Center — If Equipped”.
ECO (Fuel Saver Indicator) — If Equipped
The ECO indicator will illuminate when you are driving
in a fuel efficient manner and can be used to modify
driving habits in order to increase fuel economy.
LoW tirE
When the appropriate condition exists, the odometer dis-
play will toggle between LoW and tirE for three cycles.
“HOTOIL” Transmission Temperature Warning Message
The “HOTOIL” cluster message will appear in the odom-
eter accompanied with a chime to indicate that there is
excessive transmission fluid temperature that might oc-
cur 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 “HOT-
OIL” message turns on, stop the vehicle and run the
engine at idle or faster with the transmission in NEU-
TRAL until the message turns off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture “HOTOIL” Warning message illuminated will
eventually cause severe transmission damage or
transmission failure.
WARNING!
If the Transmission Temperature “HOTOIL” Warn-
ing message is illuminated and you continue operat-
ing the vehicle, in some circumstances you could
cause the fluid to boil over, come in contact with hot
engine or exhaust components and cause a fire.
gASCAP
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“gASCAP” message will display in the odometer display
area. Tighten the fuel filler cap properly and press the
TRIP ODOMETER button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.

CAUTION!
Never drive with your foot resting on the clutch
pedal, or attempt to hold the vehicle on a hill with the
clutch pedal partially engaged, as this will cause
abnormal wear on the clutch.
NOTE:During cold weather, you may experience in-
creased effort in shifting until the transmission fluid
warms up. This is normal.
Shifting
Fully press the clutch pedal before shifting gears. As you
release the clutch pedal, lightly press the accelerator
pedal.
You should always use first gear when starting from a
standing position.

Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided, if possible, and only
be attempted when necessary in a safe, responsible
manner. You should only drive through areas which are
designated and approved. You should tread lightly and
avoid damage to the environment. You should know
your vehicle’s abilities and be able to recover it if
something goes wrong. You should never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls, do
not attempt to restart it. Determine if it has ingested
water first. The key to any crossing is low and slow. Shift
into first gear (manual transmission), or DRIVE (auto-
matic transmission), with the transfer case in the 4L
(Low) position and proceed very slowly with a constant
slow speed {3 to 5 mph (5 to 8 km/h) maximum} and
light throttle. Keep the vehicle moving; do not try to
accelerate through the crossing. After crossing any water
higher than the bottom of the axle differentials, you
should inspect all of the vehicle fluids for signs of water
ingestion.
CAUTION!
•Water ingestion into the axles, transmission, trans-
fer case, engine or vehicle interior can occur if you
drive too fast or through too deep of water. Water
can cause permanent damage to engine, driveline
or other vehicle components, and your brakes will
be less effective once wet and/or muddy.
•This vehicle is capable of crossing through water at
a depth of 30 inches (76 cm) at speeds no greater
than 5 mph (8 km/h). Water ingestion can occur
causing damage to your vehicle.
460 STARTING AND OPERATING

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
If using a manual transmission vehicle for trailer towing,
all starts must be in first gear to avoid excessive clutch
slippage.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, you can use the
AutoStick® shift control to manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup. This action will also
provide better engine braking.
If you REGULARLY tow a trailer for more than 45
minutes of continuous operation, then change the trans-
mission fluid and filter as specified for#police, taxi, fleet,
or frequent trailer towing.#Refer to the “Maintenance
Schedule” for the proper maintenance intervals.
NOTE:Check the automatic transmission fluid level
before towing.
AutoStick — If Equipped
•When using the AutoStick shift control, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “4” if
the desired speed can be maintained. Choose “3” or
“2” if needed to maintain the desired speed.
