If the warning indicator and the warning light
come on, place the snowmobile on a level
surface and allow it to idle for one minute.
If the warning indicator and the warning light
go off, the engine oil level is sufficient, how-
ever it is getting low. Add engine oil as soon
as possible.
If the warning indicator and the warning light
do not go off, check the engine oil level in the
oil tank (see page 50 for engine oil level
checking procedures), and add engine oil if
necessary.
If the warning indicator and the warning light
still remain on, have a Yamaha dealer check
the snowmobile.
Oil pressure warning
The warning indicator comes on and “OP-
LO” (oil pressure low) appears in the odome-
ter display if the engine oil pressure is low
when the engine is started. At the same time,
the engine speed is limited to less than the
clutch engagement speed until the warning
indicator goes off.
If the engine oil pressure remains low for one
minute, the engine stops. If this occurs, have
a Yamaha dealer check the snowmobile.
TIP
If there is no engine oil in the oil passages
when the engine is started, such as after the
engine oil is changed, the warning indicator
may come on and “OP-LO” may appear in
the odometer display for a few seconds until
the oil circulates through the engine. The
snowmobile can be operated normally after
the warning indicator goes off.

immediately and allow the engine to cool
down, and then check the coolant level in the
coolant reservoir. (See page 53 for checking
procedures.)
