① Observe these precautions:
When checking the brake fluid level, make sure the top
of the brake fluid reservoir is level.
Use only the designated quality brake fluid, otherwise,
the rubber seals may deteriorate,causing leakage and
poor brake performance.
USER'S MANUAL
Recommended brake fluid: DOT 4
Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction and
lead to poor brake performance.
Be careful that water does not enter the brake fluid
reservoir when refilling. Water will significantly
lower the boiling point of the fluid and may result in
vapor lock.
Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid
immediately.
Have a dealer check the cause if the brake fluid level
goes down.
