Fuel level warning
indicator “ ”
The fuel level warning indicator and the warn-
ing light come on when the fuel level is low.
(See page 14 for details.)
The fuel level warning indicator, the warning
light, and all segments of the fuel meter start
to flash when a malfunctioning sensor, dis-
connected coupler, broken lead, or short cir-
cuit is detected by the self-diagnosis device of
the snowmobile to warn the rider of any of the
above problems.
If the fuel level warning indicator, the warning
light, and all segments of the fuel meter flash,
have a Yamaha dealer inspect the snowmo-
bile as soon as possible.

Oil level/pressure warning
indicator “ ”
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, howev-
er 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 57 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 odometer
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.
