WARNING!
closed container. Keep the master cylin-
der reservoir cap secured at all times.
Brake fluid in a open container absorbs
moisture from the air resulting in a lower
boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake fail-
ure. This could result in a collision.
• Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot en-
gine parts, causing the brake fluid to
catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should
be taken to avoid its contact with these
surfaces.
• Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This
could result in a collision.

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 Specifica-
tions" 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.
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 "Tech-
nical Specifications" for fluid specifica-
tions.
Special Additives
The manufacturer strongly
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.
CAUTION!
Do not use chemical flushes in your trans-
mission as the chemicals can damage your
transmission components. 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 trans-
