Code octane number plug (C 14 NZ, X 14 NZ, C 16 NZ, 16 LZ2 and C 18 NZ)  

  Important!   

Fuels whose octane numbers are too low can damage the engine. Fuels with higher octane numbers can always be used.  

  Adjust   

The octane number selected is printed in front of the shackle. If fuel with a different octane number is to be used, drive vehicle until fuel tank is as empty as possible and then fill with different fuel.   Ignition off, remove octane number plug from bracket, open catch, disconnect octane number plug, rotate by 180 ° , plug in and snap in.   The adjusted octane number appears in the window of the catch.
