If knocking or pinging occurs, use a different brand
of gasoline or higher octane grade. _CAUTION:_ 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. _
Recommended fuel:
For Europe: Regular unleaded gasoline
only with a research octane number of 91
or higher
For Australia: Unleaded gasoline only
Fuel tank capacity:
Total: 20 L

WARNING
_
Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine or the sun.
Be careful not to spill fuel, especially on
the engine or exhaust pipe which can
cause a fire and severe injury. Wipe up
any spilled fuel immediately.
Do not refuel right after the engine has
been running and is still very hot.
Be sure the fuel tank cap is closed secure-
ly.
