If the symbol flashes in the instrument cluster display, there is an alternator fault or a fault in the vehicle's electrical system. In addition, a message will appear. This message will disappear after about 5 seconds, but you can call it up again at any time by pressing the SET button.
You should normally be able to drive to the next available qualified workshop. However, you should avoid using electrical equipment that is not absolutely necessary because this will drain the battery.
If the coolant warning lamp in the instrument display lights up as well as the alternator warning lamp while driving page 32, stop the vehicle immediately and switch off the engine. In this case the coolant pump is no longer being driven, and there is a risk of engine damage.
