3. Fill:
• Clutch master cylinder reservoir
(with the specified amount of the specified
brake and clutch fluid)
WARNING
EWA17270
• Use only the designated clutch fluid. Other
clutch fluids may cause the rubber seals to
deteriorate, causing leakage and poor
clutch performance.
• Refill with the same type of clutch fluid that
is already in the system. Mixing clutch flu-
ids may result in a harmful chemical reac-
tion, leading to poor clutch performance.
• When refilling, be careful that water does
not enter the clutch master cylinder reser-
voir. Water will significantly lower the boil-
ing point of the clutch fluid and could cause
vapor lock.
