start mode

The start mode describes the mode in which the device should start after the ignition is switched on. In the standard configuration, the device saves the last mode set and restores it when the vehicle is started. If you want a specific mode when starting, regardless of how you parked your vehicle, this can be programmed.

The start mode can be freely programmed as desired

Last state: Press the “Sport Mode” button 5 times within 5 seconds.

Other modes: Press the button for the mode you want to learn as the start mode for about 10 seconds.

The flaps open and close 5 times to confirm successful programming of the start mode.
