Activating the ignition curve for low-octane fuel

If you are traveling to a country where fuel having at least 95 octane
(ROZ)(USA=Premium RON91) is not available, you can easily activate the
corresponding ignition curve. A plug and socket connection

1

on a

brown/black cable is located on the right side of the vehicle next to the CDI
box .
If the two connectors are connected to each other, the ignition curve for
fuel having at least 95 octane (ROZ) is activated.
If you disconnect the plug and socket connection, the ignition curve for fuel
having 80 - 94 octane (ROZ) is activated. Although this causes the engine
to lose some of its power output, it prevents poor glow ignitions and engine
damage.
