EAU11030
Turn signal indicator lights“”
and“”
The corresponding indicator light flash-
es when the turn signal switch is
pushed to the left or right.
EAU11060
Neutral indicator light“”
This indicator light comes on when the
transmission is in the neutral position.

on.
EAU11250
Oil level warning light“”
This warning light comes on when the
engine oil level is low.
The electrical circuit of the warning light
can be checked by turning the key to
“ON”.
If the warning light does not come on
for a few seconds, then go off, have a
Yamaha dealer check the electrical cir-
cuit.NOTE:

Even if the oil level is sufficient, the
warning light may flicker when
riding on a slope or during sudden
acceleration or deceleration, but
this is not a malfunction.


This model is also equipped with a
self-diagnosis device for the oil
level detection circuit. If the oil lev-
el detection circuit is defective, the
following cycle will be repeated un-
til the malfunction is corrected: The
oil level warning light will flash ten
times, then go off for 2.5 seconds.
If this occurs, have a Yamahadealer check the vehicle.
EAU11361
Fuel level warning light“”
This warning light comes on when the
fuel level drops below approximately
3.5 L (0.92 US gal) (0.77 Imp.gal).
When this occurs, refuel as soon as
possible.
The electrical circuit of the warning light
can be checked by turning the key to
“ON”.
If the warning light does not come on
for a few seconds, and then go off,
have a Yamaha dealer check the elec-
trical circuit.
