WARNING! (Continued)
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
• Use only brake fluid that has been in a tightly
closed container (both as to bottles and the master
cylinder remaining covered) to avoid contamina-
tion from foreign matter or moisture. Brake fluid,
unlike many other fluids, actually absorbs mois-
ture from the air. This lowers the boiling point of
the fluid and may cause it to boil during hard
braking and create a soft pedal pressure resistance
as the gas compresses. This condition does not
apply adequate pressure to the brakes to function
properly.

WARNING! (Continued)
• Do not allow petroleum based fluid to contami-
nate the brake fluid, all brake seal components
could be damaged, causing partial or complete
brake failure leading to a crash.
Automatic Transmission — If Equipped
Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturer’s recommended transmis-
sion fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the correct fluid type. It is
important that the transmission fluid be maintained at
the prescribed level using the recommended fluid.
