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, and will require more frequent fluid and
filter changes. Refer to “Fluids, Lubricants, and Genu-
ine Parts” in this section for fluid specifications.
Special Additives
The manufacturer strongly recommends against using
any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an engineered prod-
uct 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. Avoid using trans-
mission 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 transmis-
sion filler tube is capped and no dipstick is provided. Your
authorized dealer can check your transmission fluid level
using a special service dipstick. If you notice fluid leakage or
transmission malfunction, visit your authorized dealer im-
mediately to have the transmission fluid level checked.
Operating the vehicle with an improper fluid level can cause
severe transmission damage.
