low during operation. If the warninglight comes on during operation, stop
immediately and fill the oil tank with Ya-
malube 2 or equivalent 2-stroke engine
oil of either JASO grade “FC” or ISO
grades “EG-C” or “EG-D”. The warning
light should go off after the 2-stroke en-
gine oil tank has been refilled.
NOTE:If the warning light does not come on
when the key is in the “” position or
does not go off after the 2-stroke en-
gine oil tank has been refilled, have a
Yamaha dealer check the electrical cir-cuit.CAUTION:
ECA10010
Do not operate the vehicle until you
know that the engine oil level is suf-ficient.

Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUM2100
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.NOTE:

The coolant level must be checked
on a cold engine since the level
varies with engine temperature.


Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
2. Check the coolant level through
the check window.
NOTE:The coolant should be between theminimum and maximum level marks.3. If the coolant is at or below the
minimum level mark, remove the
cowling A. (See page 6-5.)
4. Open the reservoir cap, and then
add coolant to the maximum level
mark.
CAUTION:
ECA10470


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 ofthe coolant will be reduced.WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
