The on-board computer is activated as soon as the key is turned to position 1 in the ignition lock. You can use the on-board computer to call up information relating to your vehicle and to make and adjust settings.

You can call up the next service due date, select the display language for the instrument cluster and set other functions.

The on-board computer shows information in the multi-function display.
