368SERVICING AND MAINTENANCE
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission perfor-
mance and life. Use only the manufacturer’s
specified transmission fluid. Refer to “Fluids
And Lubricants” in “Technical Specifications”. It
is important to maintain the transmission fluid
at the correct level using the recommended
fluid. 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 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. The only exception to this policy is
the use of special dyes for diagnosing fluid
leaks in six-speed transmissions. Avoid using
transmission sealers as they may adversely
affect seals.
Fluid Level Check — Eight-Speed
Transmission
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 Level Check — Six-Speed Transmission
It is best to check the fluid level when the trans -
mission is at normal operating temperature
(158-176°F / 70-80°C). This normally occurs
after at least 15 miles (25 km) of driving. At
normal operating temperature the fluid cannot
be held comfortably between the fingertips. You
can read the transmission sump temperature in
the instrument cluster screen (refer to “Instru -
ment Cluster Display” in “Getting To Know Your
Instrument Panel” for further information).
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may
cause deterioration in transmission shift
quality and/or torque converter shudder, and
(for six-speed transmissions) will require
more frequent fluid and filter changes. 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.
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.

372SERVICING AND MAINTENANCE
Exhaust System
Inspect the entire exhaust system for leaks and
damaged parts. Devices such as hangers,
clamps, and U-bolts should be tight and in good
condition. Damaged components, burned or
blown out mufflers, burned or rusted out
exhaust pipes should be replaced according to
the procedures and specifications outlined in
the appropriate service manual.
Air Cleaner Assembly
Inspect air cleaner housing for proper assembly
and fit. Make certain that the air cleaner is prop -
erly positioned and that the cover is tight. Check
all hoses leading to the air cleaner for tightness.
The air filter element must also be clean and
serviced according to the instructions outlined
in the Scheduled Maintenance section of this
manual.Tampering With Noise Control System
Prohibited
Federal law prohibits the following acts or the
causing thereof: (1) the removal or rendering
inoperative by any person, other than for
purposes of maintenance, repair, or replace -
ment, of any device or element of design incor -
porated into any new vehicle for the purpose of
noise control prior to its sale or delivery to the
ultimate purchaser or while it is in use, or (2) the
use of the vehicle after such device or element
of design has been removed or rendered inop -
erative by any person.
Among those acts presumed to constitute
tampering are the acts listed below.
AIR CLEANER
Removal of the air cleaner.
Removal of the air cleaner filter element from
the air cleaner housing.
Removal of the air ducting.
EXHAUST SYSTEM
Removal or rendering inoperative exhaust
system components including the muffler or
tailpipe. ENGINE COOLING SYSTEM

Removal or rendering inoperative the fan
clutch.
Removal of the fan shroud.
Noise Emission Warranty
The manufacturer warrants that this vehicle as
manufactured by the manufacturer, was
designed, built and equipped to conform at the
time it left the manufacturer's control with all
applicable U.S. EPA Noise Control Regulations.
This warranty covers this vehicle as designed,
built and equipped by the manufacturer, and is
not limited to any particular part, component or
system of the vehicle manufactured by the
manufacturer. Defects in design, assembly or in
any part, component or system of the vehicle as
manufactured by the manufacturer, which, at
the time it left the manufacturer's control,
caused noise emissions to exceed Federal stan -
dards, are covered by this warranty for the life of
the vehicle.
