CLUTCH HYDRAULIC SYSTEM — MANUAL
T
RANSMISSION (IF EQUIPPED)
The clutch hydraulic system is fed by a
segregated volume of fluid within the brake
system master cylinder reservoir. In the event of
leakage or wear, use only the manufacturer's
recommended brake fluid. Refer to “Fluids And
Lubricants” in “Technical Specifications” for
further information.
MANUAL TRANSMISSION — IF EQUIPPED
Fluid Level Check
Check the fluid level by removing the fill plug on
the left side of the transmission. The fluid level
should be 1/4 inch (6.4mm) below the bottom
of the fill hole. Add fluid, if necessary, to
maintain the proper level. Refer to “Fluids And
Lubricants” in “Technical Specifications” for
further information.
Change Transmission Fluid
If contaminated with water, change the fluid
immediately. See an authorized dealer for
service.
Refer to the “Maintenance Plan” in this section
for the proper maintenance intervals.
AUTOMATIC TRANSMISSION — IF
E
QUIPPED
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission
performance and life. Use only the
manufacturer's specified transmission fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications. It is
important to maintain the transmission fluid at
the correct level using the recommended fluid.
NOTE:
No chemical flushes should be used in any
transmission; only the approved lubricant
should be used.
Special Additives
The manufacturer strongly recommends
against using any special additives in the
transmission. 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.
CAUTION!
Using a transmission fluid other than the
manufacturer's recommended fluid may
cause deterioration in transmission shift
quality and/or damage to the transmission.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications.
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may
cause deterioration in transmission shift
quality and/or torque converter shudder.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications.
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.

268SERVICING AND MAINTENANCE
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.
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
E
QUIPPED
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!
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.

Change Axle Fluid
Refer to “Scheduled Servicing” in “Servicing
And Maintenance” for the proper maintenance
intervals.
NOTE:
For race track usage it is recommended that the
axle fluid be changed every 4 hours of on track
time.
RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.
TIRES
TIRE SAFETY INFORMATION
Tire safety information will cover aspects of the
following information: Tire Markings, Tire
Identification Numbers, Tire Terminology and
Definitions, Tire Pressures, and Tire Loading.
Tire Markings

Tire Markings

NOTE:
P (Passenger) — Metric tire sizing is based on
US design standards. P-Metric tires have the
letter “P” molded into the sidewall preceding
the size designation.
Example: P215/65R15 95H.
European — Metric tire sizing is based on
European design standards. Tires designed
to this standard have the tire size molded
into the sidewall beginning with the section
width. The letter "P" is absent from this tire
size designation. Example: 215/65R15 96H.
LT (Light Truck) — Metric tire sizing is based
on US design standards. The size designation
for LT-Metric tires is the same as for P-Metric
tires except for the letters “LT” that are
molded into the sidewall preceding the size
designation. Example: LT235/85R16.
Temporary spare tires are designed for
temporary emergency use only. Temporary
high pressure compact spare tires have the
letter “T” or “S” molded into the sidewall
preceding the size designation.
Example: T145/80D18 103M.
High flotation tire sizing is based on US
design standards and it begins with the tire
diameter molded into the sidewall.
Example: 31x10.5 R15 LT.
