stop the vehicle and shut off the engine as soon as possible.
Wait for oil temperature to return to normal levels.
— Transmission Temperature Warning Light — If
Equipped
This warning light will illuminate to warn of a high
transmission fluid temperature. This may occur with
strenuous usage such as trailer towing. If this light turns
on, stop the vehicle and run the engine at idle or slightly
faster, with the transmission in PARK or NEUTRAL, until
the light turns off. Once the light turns off, you may
continue to drive normally.
WARNING!
If you continue operating the vehicle when the Trans-
mission Temperature Warning Light is illuminated you
could cause the fluid to boil over, come in contact with
hot engine or exhaust components and cause a fire.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
— Vehicle Security Warning Light — If Equipped
This light will flash at a fast rate for approximately 15
seconds when the vehicle security alarm is arming, and
then will flash slowly until the vehicle is disarmed.
Yellow Warning Lights
— Engine Check/Malfunction Indicator Warning
Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a
part of an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission control sys-
tems. This warning light will illuminate when the ignition
is in the ON/RUN position before engine start. If the bulb
does not come on when turning the ignition switch from
OFF to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap, poor
quality fuel, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through
several typical driving styles. In most situations, the ve-
hicle will drive normally and will not require towing.

Automatic Transmission
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 recom-
mended fluid.
NOTE:No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
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 transmis-
sion 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.
