Fluid and Filter Changes
Refer to the “Maintenance Schedule” in Section 8 of this
manual for the recommended transmission fluid and
filter change intervals.
If the transmission is disassembled for any reason, the
fluid and filter should be changed.
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 to aid in detecting fluid
leaks. In addition, avoid using transmission sealers as
they may adversely affect seals.
All Wheel Drive (AWD) — If Equipped
The all wheel drive system consists of a Transfer Case
and Front Differential. The exterior surface of these
components should be inspected for evidence of fluid
leaks. Confirmed leaks should be repaired as soon as
possible.
The transfer case fluid inspection plug is located in the
middle of the rear housing. To inspect the transfer case
fluid level, remove the inspection plug. The fluid level
should be even with the bottom of the hole. The transfer
case fill plug is located on the rear housing near the
output shaft.
The front differential fill plug is located on the outer
cover near the halfshaft attachment. To inspect the differ-
ential fluid level, remove the fill plug. The fluid level
should be even with or slightly below the bottom of the
hole.

manual for the recommended transfer case fluid change
intervals.
Front and Rear Wheel Bearings
Front and rear wheel bearings are permanently sealed.
No regular maintenance is required for these compo-
nents.
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 chemicals 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 contami-
nants, road surfaces on which the vehicle is operated,extreme hot or cold weather and other extreme condi-
tions will have an adverse effect on paint, metal trim, and
underbody 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 seacoast localities.
•Atmospheric fallout/industrial pollutants.
