Immediately wipe off spilled fuel with
a clean, dry, soft cloth, since fuel may
deteriorate painted surfaces or plas-
tic parts.
CAUTION:
EAU04284
Recommended fuel:
REGULAR UNLEADED
GASOLINE ONLY
Fuel tank capacity:
Total amount:
10.9 L
Reserve amount:
1.9 L
ECA00104
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
Your Yamaha engine has been
designed to use regular unleaded
gasoline with a research octane
number of 91 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand or premium unleaded
fuel. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
CAUTION:
EAU03098
Catalytic converter
This scooter is equipped with a catalytic
converter in the muffler.
EW000128
The exhaust system is hot after
operation. Make sure that the
exhaust system has cooled down
before doing any maintenance work.
EC000114
The following precautions must be
observed to prevent a fire hazard or
other damages.
•Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.
•Never park the scooter near
possible fire hazards such as
grass or other materials that
easily burn.
•Do not allow the engine to idle
too long.
