2013 JEEP WRANGLER UNLIMITED automatic transmission fluid

WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do
not overfill. Use only manufacturer’s recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for further information.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave an
automatic transmission in PARK, or manual transmission
in REVERSE or first gear.The parking brake lever is located in the center console.
To apply the parking brake, pull the lever up as firmly as
possible. To release the parking brake, pull the lever up
slightly, press the center button, then lower the lever
completely.

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. How-
ever, if frequent shifting occurs while in this range, use
the Electronic Range Select (ERS) shift control to select a
lower gear range. NOTE: Using a lower gear range while operating the
vehicle under heavy loading conditions will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup. This action will also
provide better engine braking.
If you REGULARLY tow a trailer for more than 45 min-
utes of continuous operation, then change the transmis-
sion 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.530 STARTING AND OPERATING

Automatic Transmission – If Equipped
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s recommended transmission
fluid. Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further fluid specifica-
tions. It is important to maintain the transmission fluid at
the correct level using the recommended fluid.
NOTE: No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter (Continued) CAUTION! (Continued)shudder. Using a transmission fluid other than the
manufacturer’s recommended fluid will require
more frequent fluid and filter changes. Refer to
“Fluids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information.
Special Additives
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes for diagnosing fluid
leaks. Avoid using transmission sealers as they may
adversely affect seals.

Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and transmission as
needed
• Check function of all interior and exterior lights
Required Maintenance Intervals .
Refer to the maintenance schedules on the following
page for the required maintenance intervals. At Every Oil Change Interval As Indicated By Oil
Change Indicator System:
• Change oil and filter
• Rotate the tires. Rotate at the first sign of irregu-
lar wear, even if it occurs before the oil indicator
system turns on.
• Inspect battery and clean and tighten terminals as
required
• Inspect automatic transmission fluid if equipped
with dipstick
• Inspect brake pads, shoes, rotors, drums, hoses
and park brake
• Inspect engine cooling system protection and
hoses
