The front fog light can only be switched on when the fog-light switch on the light switch is in position 1 or position 2 and if the ignition is in position ON (+15 or +54).

The front fog light is suited to individual markets and therefore has three different programming alternatives with different functions. Each alternative also has a corresponding alternative with the headlamps.

The programming alternatives for fog lights (ON/OFF) depend on a number of parameters which give three alternatives. A dash in the table indicates that the lighting logic is independent of the value of the relevant parameter.
