SERVICING AND MAINTENANCE
Frequency Of Fluid Change
Under normal operating conditions, the fluid installed at
the factory will give satisfactory lubrication for the life of
the vehicle. If the fluid becomes contaminated with
water, it should be changed immediately. Otherwise,
change the fluid as recommended in the Maintenance
Plan. Refer to the Maintenance Plan for the proper
maintenance intervals
page 295.
Selection Of Lubricant
Use only the manufacturer recommended manual
transmission fluid
page 363.
AUTOMATIC TRANSMISSION —
IF EQUIPPED
Special Additives
It is strongly recommended against using any special
additives in the transmission. Automatic Transmission
Fluid (ATF) is an engineered product and its perfor-
mance may be impaired by supplemental additives.
Therefore, do not add any fluid additives to the trans-
mission. 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
The fluid level is preset at the factory and does not
require adjustment under normal operating conditions.
Routine fluid level checks are not required; therefore
the transmission has no dipstick. An authorized dealer
can check your transmission fluid level using special
service tools. If you notice fluid leakage or transmission
malfunction, visit an authorized dealer immediately to
have the transmission fluid level checked. Operating
the vehicle with an improper fluid level can cause
severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit an authorized
dealer immediately. Severe transmission damage
may occur. An authorized dealer has the proper tools
to adjust the fluid level accurately.
Fluid And Filter Changes
Under normal operating conditions, the fluid installed at
the factory will provide satisfactory lubrication for the
life of the vehicle.
Routine fluid and filter changes are not required. How-
ever, change the fluid and filter if the fluid becomes
contaminated (with water, etc.), or if the transmission is
disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life.
Use only the manufacturer specified transmission fluid
page 363. It is important to maintain the transmis-
sion fluid at the correct level using the recommended
fluid.
NOTE:
No chemical flushes should be used in any transmis-
sion; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufac-
turer recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder
page 363.

FUSES

General Information
WARNING!
When replacing a blown fuse, always use an appro-
priate replacement fuse with the same amp rating
as the original fuse. Never replace a fuse with
another fuse of higher amp rating. The use of a
fuse with a rating other than indicated may result
in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
Never replace a blown fuse with metal wires or any
other material. Failure to use proper fuses may
result in serious personal injury, fire and/or prop-
erty damage.
Before replacing a fuse, make sure that the igni-
tion is off and that all the other services are
switched off and/or disengaged.
