CAUTION:

● If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.
●
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the cool-
ing system will not be protected
against frost and corrosion.
●
If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.
