Self-diagnosis deviceThis model is equipped with a self-
diagnosis device for the throttle posi-
tion sensor, oil change indicator light,
speedometer unit circuits. If any of
those circuits are defective, the oil
change indicator light will flash.
If the indicator light flashes or comes
on, have a Yamaha dealer check the
motorcycle as soon as possible.NOTE:
The oil change indicator light may
flash when the engine is revved with
the scooter on the centerstand, but
this does not indicate a malfunction.

Speedometer unit The speedometer unit is equipped
with a speedometer, an odometer
and a tripmeter. The speedometer
shows riding speed. The odometer
shows the total distance traveled.
The tripmeter shows the distance
traveled since it was last set to zero.
Pushing the ÒTRIPÓ button switches
the display between the odometer
mode ÒODOÓ and the tripmeter mode
ÒTRIPÓ. To reset the tripmeter, enter
the ÒTRIPÓ mode, and then hold downthe ÒTRIPÓ button for at least one
second. The tripmeter can be used
together with the fuel gauge to esti-
mate the distance that can be trav-
eled with a full tank of fuel. This infor-
mation will enable you to plan future
fuel stops.INSTRUMENT AND CONTROL FUNCTIONS

Engine oil
Type

classificationAPI Service SE, SF, SG type
or highercCBe sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled ÒEnergy
ConservingÓ) contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting in reduced
component life and poor engine performance.
