Checking the brake fluid level
Before riding, check that the brake fluid is
above the lower level. Check the brake fluid
level with the top of the reservoir level. Re-
plenish the brake fluid if necessary.
1. Lower level
Specified brake fluid:
DOT 4
EWS00821
WARNING
Improper maintenance can result in loss
of braking ability. Observe these precau-
tions:
 Insufficient brake fluid may allow air to
enter the brake system, reducing brak-
ing performance.
 Clean the filler cap before removing.
Use only DOT 4 brake fluid from a sealed
container.
 Use only the specified brake fluid; other-
wise, the rubber seals may deteriorate,
causing leakage.
 Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion.
