NOTE:
Fluid level is specified at optimum position (range) for ordinary use. Accordingly, if the vehicle is used often
under hard conditions such as on very rough roads or in mountainous areas, fluid may bleed out from cap
air vent hole. This is not a problem. If a customer complains strongly and is not likely to be satisfied with
the leakage, lower the fluid level to the extent that fluid will not bleed out under the conditions described,
and have the customer check the fluid level and its quality more frequency than usual.
