2013 JEEP WRANGLER check transmission fluid

Power Steering Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an autho-
rized dealer.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power
steering components. Such damage is not covered by
the New Vehicle Limited Warranty.
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.
456 STARTING AND OPERATING

If you REGULARLY tow a trailer for more than 45
minutes of continuous operation, then change the trans-
mission fluid and filter as specified forpolice, 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.
Electronic Speed Control – If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

STARTING AND OPERATING 539

CAUTION!(Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. The
engine oil level should be checked five minutes after a
warmed up engine has been shut off. Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding 1 U.S. Quart (0.95L) of oil when the
reading is at the bottom of the SAFE zone will result in a
reading at the top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage
your engine.
574 MAINTAINING YOUR VEHICLE

Special Additives
The manufacturer strongly recommends against using
any special additives in the transmission.
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.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check
It is best to check the fluid level when the transmission is
at normal operating temperature (approximately 180° F
(82° C). This occurs after at least 15 miles (25 km) of
driving. At normal operating temperature, the fluid
cannot be held comfortably between the fingertips.
Use the following procedure to check the transmission
fluid level properly:
1. Park the vehicle on level ground.
2. Run the engine at idle speed and normal operatingtemperature.
3. Fully apply the parking brake, and press the brake pedal.

4. Place the shift lever momentarily into each gear posi-tion (allowing time for the transmission to fully en-
gage in each position), ending with the shift lever in
PARK.
5. Remove the dipstick, wipe it clean and reinsert it until seated.
6. Remove the dipstick again and note the fluid level on both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
The fluid level should be between the HOT (upper)
reference holes on the dipstick at normal operating
temperature. If the fluid level is low, add fluid through
the dipstick tube to bring it to the proper level. Do not
overfill. After adding any quantity of oil through the
dipstick tube, wait a minimum of two minutes for the
oil to fully drain into the transmission before recheck-
ing the fluid level. NOTE:
•
The holes in the dipstick will be full of fluid if the
actual level is at or above the hole.
• If it is necessary to check the transmission below the
operating temperature, the fluid level should be be-
tween the two COLD (lower) holes on the dipstick
with the fluid at approximately 80° F (27° C). If the
fluid level is correctly established at 80° F (27° C), it
should be between the HOT (upper) reference holes
when the transmission reaches 180° F (82° C). Remem-
ber it is best to check the level at the normal operating
temperature.
596 MAINTAINING YOUR VEHICLE

CAUTION!
If the fluid temperature is below 50° F (10° C), it may
not register on the dipstick. Do not add fluid until
the temperature is elevated enough to produce an
accurate reading. Run the engine at idle, in PARK, to
warm the fluid.
7. Check for leaks. Release the parking brake.
NOTE: To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
sure that the dipstick cap is properly reseated. It is
normal for the dipstick cap to spring back slightly from
its fully seated position, as long as its seal remains
engaged in the dipstick tube.
Fluid And Filter Changes
Refer to the “Maintenance Schedule” for the proper
maintenance intervals. In addition, change the fluid and filter if the transmission
is disassembled for any reason.
Clutch Hydraulic System (Manual Transmission) –
If Equipped
The clutch hydraulic system is fed by a segregated
volume of fluid within the brake system master cylinder
reservoir. In the event of leakage or wear, use only the
manufacturer’s recommended brake fluid. Refer to “Flu-
ids, Lubricants, and Genuine Parts” in “Maintaining Your
Vehicle” for further information.
Manual Transmission – If Equipped
Selection Of Lubricant
Use only manufacturer’s recommended manual transmis-
sion fluid. Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for further information.

NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
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
• Inspect exhaust system
• Inspect engine air cleaner if using in dusty or
off-road conditions
• Inspect all door latches for presence of grease,
reapply if necessary.
