Before the trip you should take the time to check all electrical appliances and sockets, the central electronics and the displays for proper functioning. See to the auxiliary batteries too and charge them if required. Start up your refrigerator again shortly before you begin your trip and set the fridge to the desired temperature.

The Viano MARCO POLO gives you a great deal of independence for power supply. If you use an external power source for charging, not only the auxiliary battery is charged, but the vehicle battery too. And don’t forget to take an adapter cable for the electricity connection.
