WARNING! (Continued)
•
Use only brake fluid that has been in a tightly-
closed container to avoid contamination from for-
eign matter or moisture.
CAUTION!
Do not allow a petroleum-base fluid to contaminate
the brake fluid. Seal damage may result.Rear Axle And 4x4 Front Driving Axle Fluid LevelFor normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the axle assembly should be
inspected. If gear oil leakage is suspected inspect the
fluid level. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the correct fluid type.This inspection should be made with the vehicle in a level
position. The fluid level should be even with the bottom
of the fill hole for the manufacturer’s C205F HD front
axles. The fluid level should be 5/8 in (16 mm) below the
fill hole on 9 1/4 in manufacturer’s rear axles.
For all 2500/3500 Model axles, the fluid level should be
1/4” ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole on
the 9.25 in front and 3/4 in ± 1/4 in (19 mm ± 6.4 mm) on
10.5 in rear axles. The 11.5 in rear axle level should be
1/4 in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole.
Drain and RefillRefer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.Lubricant SelectionRefer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.

NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
2500/3500 Model Axles DO NOT REQUIREany limited
slip oil additive (friction modifiers).Transfer Case
Drain And RefillRefer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.Lubricant SelectionRefer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.
Fluid Level CheckThis fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of the
filler plug hole with the vehicle in a level position.Automatic Transmission
Selection Of LubricantIt is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only the manufacturer ’s recommended trans-
mission fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the correct fluid type. It is
important that the transmission fluid be maintained at
the prescribed level using the recommended fluid. No
chemical flushes should be used in any transmission;
only the approved lubricant may be used.

dipstick cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in the
dipstick tube.Automatic Transmission Fluid and Filter ChangeRefer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
NOTE:If the transmission is disassembled for any
reason, the fluid and filter(s) should be changed.
It is important that the proper lubricant is used in the
transmission. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the correct fluid type.Special AdditivesAutomatic 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 to aid in detecting fluid
leaks. In addition, avoid using transmission sealers as
they may adversely affect seals.
Appearance Care and Protection from Corrosion
Protection of Body and Paint from CorrosionVehicle 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 affect 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.

Cleaning Plastic Instrument Cluster LensesThe 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 MaintenanceDo not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage can also weaken the fabric.
If the belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the belts from the car to
wash them.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
Dry with a soft tissue.

EMISSIONS CONTROL SYSTEM MAINTENANCEThe Scheduled Maintenance services listed inbold type
must be done at the times or mileages specified to ensure
the continued proper functioning of the emissions control
system. These and all other maintenance services in-
cluded 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 should also be done anytime a
malfunction is suspected. NOTE:
Maintenance, replacement or repair of the emis-
sions control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part that has been
certified pursuant to U.S. EPA or in the State of Califor-
nia, California Air Resources Board regulations.482 MAINTENANCE SCHEDULES

MAINTENANCE SCHEDULEThe oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
The “Change Oil” message will flash in the instrument
cluster odometer and a single chime will sound, indicat-
ing that an oil change is necessary.
Based on engine operation conditions the oil change
indicator message will illuminate, this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 miles (805 km).
NOTE:•
The oil change indicator message will not monitor the
time since the last oil change. Change your vehicles oil
if it has been six months since your last oil change even
if the oil change indicator message is NOT illumi-
nated.
•
Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
•
Under no circumstances should oil change intervals
exceed 6,000 miles (10 000 km) or six months, which-
ever comes first.
Your dealer will reset the oil change indicator message
after completing the scheduled oil change. If this sched-
uled oil change is performed by someone other than your
dealer the message can be reset by referring to the steps
described under “Odometer/Trip Odometer” under “In-
strument Cluster Description” in Section 4 of this
manual.

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 and add if
required.
Once a Month
•
Check tire pressure and look for unusual wear or
damage.
•
Inspect the battery, clean and tighten the terminals as
required.
•
Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and transmission and
add as needed.
•
Check all lights and other electrical items for correct
operation.
At Each Oil Change
•
Change the engine oil filter.
•
Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.Required Maintenance IntervalsRefer to the Maintenance Schedules on the following
