If the oil level warning indicator and the warn-
ing light do not go off, check the engine oil
level in the oil tank (see page 70 for engine oil
level checking procedures), and add engine
oil if necessary.
If the oil level warning indicator and the warn-
ing light still remain on, have a Yamaha dealer
check the snowmobile.

Oil level/pressure warning
indicator “ ” (RST1NTF /
RST1NTFY)
The oil level/pressure warning indicator has
two functions. The warning indicator comes
on when the engine oil level is low and when
the engine oil pressure is low. The functions
are explained in the following sections.
Oil level warning
The warning indicator and the warning light
come on when the engine oil level is low.
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 70 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.
