transaxle Clutch Release System should not require fluid
replacement during the life of the vehicle. If the Brake
Fluid Reservoir is low, and the brake system does not
indicate any leaks or other problems, it may be a result of
a leak in the Hydraulic Clutch Release System. See your
local authorized dealer for service.
Use only manufacturer’s recommended brake fluid. Re-
fer to “Fluids, Lubricants, and Genuine Parts”, found
later in this section, for the correct fluid type.
WARNING!
Use of a brake fluid that has a lower initial boiling
point than the recommended MOPAR
௡ DOT 3 prod-
uct, or a brake fluid that is unidentified as to FMVSS
specification, may result in sudden brake failure
during hard, prolonged braking. You could have an
accident.
CAUTION!
Use of improper brake fluids will affect overall
clutch system performance. Improper brake fluids
may damage the clutch system resulting in loss of
clutch function and the ability to shift the transaxle.
WARNING!
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
