• If the coolant level is below level ‘Low’, add
enough specified coolant to provide protection
against freezing and corrosion. Coolant level
should be between the MAX and MIN. But do
not exceed level
‘MAX’.
• If frequent additions are required, contact an
authorized dealer for a cooling system
inspection.
• Use only soft (demineralized) water in the
coolant mixture.
• The engine has aluminum engine parts and
must be protected by an ethylene-glycol-based
coolant to prevent corrosion and freezing.
• DO NOT USE alcohol or methanol coolant or
mix them with the specified coolant.
• DO NOT USE a solution that contains more
than 60% antifreeze or less than 35% antifreeze,
which would reduce the effectiveness of the
solution. For mixture percentages, refer to the
table.
• In order to drain engine coolant, please use a
screwdriver to loosen the drain plug
