Vehicles with tire pressure monitoring system

On vehicles with tire pressure monitoring system, the tire pressure must be resaved or adapted after each change from summer to winter tires or vice versa. Refer to Owner's Manual.

Permission stipulations in Germany

Only when using winter tires is it permitted that the highest speed attainable by the vehicle lies above the highest speed of winter tires specified by the speed symbol.

In this case, an information label must be applied with the following content:

Attention, winter tires!
Maximum permissible speed...km/h
