2006 JEEP WRANGLER maintenance

(cross-hatched area) on the oil level indicator. The fluid
level indicator should be in the COLD region at 70° F (21°
C) fluid temperature.
If the fluid level is low, add sufficient fluid to bring to the
proper level. Refer to Fluids, Lubricants and Genuine
Parts for correct fluid type.
Fluid is added through the dipstick tube.
NOTE: To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
certain that the dipstick cap is properly reseated.
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 a sealed maintenance free
system. In the event of leakage or other malfunction, the
system must be replaced.
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.

Selection of Lubricant
Use only manufacturer’s recommended fluid, refer to
Fluids, Lubricants, and Genuine Parts for correct fluid
type.
Maintenance After Off-Road Driving
After extended operation in mud, sand or water, or
similar dirty conditions, have your brake drums, brake
linings, and axle joints inspected and cleaned as soon as
possible. This will prevent any abrasive material from
causing excessive wear or unpredictable braking action.
Following off-road usage, completely inspect the under-
body of your vehicle. Check tires, body structure, steer-
ing, suspension and exhaust system for damage. Check
threaded fasteners for looseness, particularly on the
chassis, drivetrain components, steering and suspension.
Retighten, if required, to torque values specified in the
Service Manual. Also check for accumulations of vegeta-
tion or brush that could become a fire hazard, or conceal damage to fuel lines, brake hoses, axle pinion seals, and
propeller shafts. Check air conditioning drain tube on the
lower dash wall in the engine compartment for mud or
debris, and clean as required. A plugged tube will
adversely affect air conditioning performance.
CAUTION!
Under frequent heavy-duty driving conditions,
change all lubricants, and lubricate body compo-
nents and steering linkage more often than in nor-
mal service to prevent excessive wear.
Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and those that are sprayed on

trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
road surfaces on which the vehicle is operated, extreme
hot or cold weather and other extreme conditions will
have an adverse effect on paint, metal trim, and under-
body protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
The most common causes are:
•Road salt, dirt and moisture accumulation.
•Stone and gravel impact.
•Insects, tree sap and tar.
•Salt in the air near sea-coast localities.
•Atmospheric fallout/industrial pollutants.
•Bird droppings.
Washing
•
Wash your vehicle regularly. Always wash your ve-
hicle in the shade using Mopar Car Wash or a mild
car wash soap, and rinse the panels completely with
clear water.
•If insects, tar, or other similar deposits have accumu-
lated on your vehicle, use Mopar Super Kleen Bug
and Tar Remover to remove.
•Use Mopar  Cleaner Wax to remove road film, stains,
and to protect your paint finish. Take care never to
scratch the paint.
298 MAINTAINING YOUR VEHICLE

Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
1. Clean with a wet soft rag. A mild soap solution may be
used, but do not use high alcohol content or abrasive
cleaners. If soap is used, wipe clean with a clean damp
rag.
2. Dry with a soft tissue.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage will also weaken the fabric.
If the belts need cleaning, use Mopar Total Clean, a mild
soap solution, or lukewarm water. Do not remove the
belts from the vehicle to wash them. Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
Carpet
Vacuum your carpet regularly to prevent a soil build-up.
Shampoo soiled carpet with a reliable upholstery cleaner,
using a natural sponge or soft bristle brush. After carpet
dries, vacuum it thoroughly.
WARNING!
Only remove the carpet for cleaning purposes. It
provides insulation against high floor pan tempera-
tures. You or your passengers could be burned if the
carpet is not properly in place. Always put the carpet
back into the vehicle before driving.

EMISSION CONTROL SYSTEM MAINTENANCE
The “Scheduled” maintenance services, listed inbold
type must be done at the times or mileages specified to
assure the continued proper functioning of the emission
control system. These, and all other maintenance services
included in this manual, should be done to provide best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions such as dusty areas and very short trip
driving.
Inspection and service also should be done any time a
malfunction is suspected.
NOTE: Maintenance, replacement, or repair of the emis-
sion control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part which has been
certified pursuant to U.S. EPA or, in the State of Califor-
nia, California Air Resources Board regulations.
MAINTENANCE SCHEDULES
There are two maintenance schedules that show the
required service for your vehicle.
First is Schedule B. It is for vehicles that are operated
under the conditions that are listed below and at the
beginning of the schedule.
•Day or night temperatures are below 32°F (0°C)
•Stop and go driving
•Excessive engine idling
•Driving in dusty conditions
•Short trips of less than 10 miles (16.2 km)
•More than 50% of your driving is at sustained high
speeds during hot weather, above 90°F (32°C)
•Trailer towing
•Taxi, police, or delivery service (commercial service)

•Off-road or desert driving
•If equipped for and operated with E-85 (ethanol)
fuel.
NOTE: IfANY of these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow “Schedule B” of the
“Maintenance Schedules” section of this manual.
NOTE: IfANY of these apply to you then flush and
replace your engine coolant/anti-freeze every 102,000
miles (170 000 km) or 60 months, whichever comes first,
and follow “Schedule B” of the “Maintenance Schedules”
section of this manual.
NOTE: Most vehicles are operated under the conditions
listed for Schedule “B.”
Second is Schedule “A”. It is for vehicles that are not
operated under any of the conditions listed under Sched-
ule “B.” Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
•Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
•Check the windshield washer solvent, add as required.
