Important safety notes
Only use the on-board computer when traffic conditions permit. Operating it diverts your attention from the traffic and may cause an accident.
WARNINGIf the instrument cluster or multifunction display fails, no messages can be shown.
You will then no longer have information on driving conditions (such as speed and outside temperature), and you will no longer be warned by the warning and indicator lamps or by messages about possible faults in certain systems. The vehicle's handling may be impaired. Adjust your driving style and speed accordingly.
Contact a qualified workshop immediately.
WARNINGThe on-board computer only stores and displays messages and warnings relating to certain systems.
Therefore, always make sure the vehicle is in full operating condition. Otherwise, you could cause an accident.
WARNINGIf maintenance work is not carried out correctly, the operating safety of your vehicle may be impaired. You could then lose control of the vehicle and cause an accident. In addition, the safety systems may no longer be able to provide you and other persons with the intended protection.
Always have maintenance work carried out by a qualified workshop.
An illustration of the instrument cluster can be found in the chapter "At a glance".
