NOTICE
If the warning light comes on when
the engine is running, stop the en-
gine and check the oil level. If the oil
level is low, add sufficient oil of the
recommended type. If the warning
light remains on after adding oil,
stop the engine and have a Yamaha
dealer check the vehicle.
Coolant temperature warning
light " "
This warning light comes on when the
engine is overheating. If this occurs,
stop the engine immediately and allow
the engine to cool. (See page 6-38.)
For vehicles with a radiator fan, the ra-
diator fan(s) automatically switch on or
off according to the coolant tempera-
ture.

Malfunction indicator light
(MIL) " "
This light comes on or flashes if a prob-
lem is detected in the engine or other
vehicle control system. If this occurs,
have a Yamaha dealer check the on-
EAU11449
board diagnostic system. The electri-
cal circuit of the warning light can be
checked by turning the vehicle power
on. The light should come on for a few
seconds, and then go off. If the light
does not come on initially when the ve-
hicle power is turned on, or if the light
remains on, have a Yamaha dealer
check the vehicle.
NOTICE
If the MIL starts flashing, reduce en-
gine speed to prevent exhaust sys-
tem damage.

or excessive/improper use of the mo-
torcycle. To prevent this, observe
these precautions.
