START/STOP button and fixture for the ID transmitter/remote key

The START/STOP button can be used to switch the terminals (0, R, 15, R, 0) on a rolling basis. The engine can be started by depressing the clutch or the brake (manual gearbox/automatic transmission) and pressing the START/STOP button. Prerequisite: a valid ID transmitter has been detected.

For vehicles without Comfort Access: The remote key must be locked in the fixture to start the engine. For vehicles with Comfort Access: The remote key must be inserted in the fixture if the ID transmitter battery is flat. The engine can then be started up. Inserting the ID transmitter into the fixture deactivates Comfort Access.
