Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter. Do
not allow petroleum base fluid to contaminate the brake
fluid as seal damage will result.
Automatic Transmission
Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturer’s recommended transmis-
sion fluid, refer to Fluids, Lubricants, and Genuine Parts
for correct fluid type. It is important that the transmission
fluid be maintained at the prescribed level using the
recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturer’s recommended fluid will result in
more frequent fluid and filter changes. Refer to
Fluids, Lubricants, and Genuine Parts for correct
fluid type.
Fluid Level Check — 42RLE (3.7L Engine)
Your vehicle is equipped with a capped dipstick tube, it
is sealed and should not be tampered with. Your autho-
rized dealer has the proper tools to ensure that the fluid
level is set properly.

Fluid Level Check — W5A580 (4.0L Engine)
Your vehicle is equipped with a capped dipstick tube, it
is sealed and should not be tampered with. Your autho-
rized dealer has the proper tools to ensure that the fluid
level is set properly.
Special Additives
The manufacturer strongly recommends against the ad-
dition of any additives to the transmission. The only
exception to this policy is the use of special dyes to aid in
detecting fluid leaks. The use of transmission sealers
should be avoided as they may adversely affect seals.
Hydraulic Clutch Fluid — Manual Transmission
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
manufacturer’s recommended brake fluid, refer to Fluids,
Lubricants, and Genuine Parts for correct fluid type.
Manual Transmission
Selection of Lubricant
Use only manufacturer’s recommended manual trans-
mission fluid, refer to Fluids, Lubricants, and Genuine
Parts for correct fluid type.
Fluid Level Check
Check the fluid level by removing the fill plug. The fluid
level should be between the bottom of the fill hole and a
point not more than 3/16” (4.76 mm) below the bottom of
the hole.
Add fluid, if necessary, to maintain the proper level.

Once a Month
•Check the tire pressure and look for unusual wear or
damage.
•Inspect the battery and clean and tighten the terminals
as required.
•Check the fluid levels of the coolant reservoir, brake
master cylinder, and transmission, and add as needed.
•Check all lights and all other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the exhaust system.
•Inspect brake hoses.
•Inspect the CV joints (If equipped) and front suspen-
sion components.
•Check the coolant level, hoses, and clamps.
•After completion of off-road operation, the underside
of the vehicle should be thoroughly inspected. Exam-
ine threaded fasteners for looseness.
