SERVICING AND MAINTENANCE 265
Special Additives
The manufacturer strongly recommends
against using any special additives in the trans-
mission. Automatic Transmission Fluid (ATF) is
an engineered product and its performance
may be impaired by supplemental additives.
Therefore, do not add any fluid additives to the
transmission. Avoid using transmission sealers
as they may adversely affect seals.
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 immedi-
ately to have the transmission fluid level
checked. Operating the vehicle with an
improper fluid level can cause severe transmis-
sion damage.
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. However, change the fluid and filter if
the fluid becomes contaminated (with water,
etc.), or if the transmission is disassembled for
any reason.
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 fill/inspection plug is
located in the middle of the rear housing. To
inspect the transfer case fluid level, remove the
fill/inspection plug. The fluid level should be
even with the bottom of the hole. Use this plug
to add fluid as required.
The front differential fill plug is located on the
outer cover near the halfshaft attachment. To
inspect the differential fluid level, remove the fill
plug. The fluid level should be even with or
slightly below the bottom of the hole.
Fluid Changes
Refer to “Scheduled Servicing” in “Servicing
And Maintenance” for the proper maintenance
intervals.
Rear Axle
Fluid Level Check
Checking the fluid level while the vehicle is on
level ground and has been stationary for
15 minutes will improve the accuracy of the
fluid level reading.
Check the fluid level by removing the fill plug on
the axle. The fluid level should be 1-2.5 mm
below the fill plug. Add fluid, if necessary, to
maintain the proper level. Refer to “Fluids And
Lubricants” in "Servicing And Maintenance” for
further information.
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such damage
is not covered by the New Vehicle Limited
Warranty.
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.
