The Four-C switch is beside the other switched on the lower section of the climate control module (CCM).

There are two different driving modes which can be selected:

COMFORT
SPORT.

The "COMFORT" driving mode is active when the switched is not activated. The "SPORT" mode is activated when the switch is pressed. This is confirmed by a green LED in the switch.

In the "COMFORT" driving mode, ride comfort is prioritized. In "SPORT" mode driving pleasure is prioritized.

The switch on the climate control module (CCM) is connected to the central electronic module (CEM). The central electronic module (CEM) is in turn connected to the suspension module (SUM) via the Controller area network (CAN).

There are diagnostics for the climate control module (CCM).
