If
any
coolant gets in your eyes, rinse them with
water and consult a doct or immediately.

thoroughly with plenty of water.
• The effectiveness of coolant decreases with the
accumulation of rust or if there is a change in the
mixing proportion during usage. Therefore, for
best performance, change the coolan t regularly
as specified i n the maintenance schedule.
• Mix only distilled, low mineral water with the
antifreeze.
