Winter tyres
Winter tyres are designed for driving in road conditions with ice and snow. Your winter tyres' tread depth should be deeper than that of regular tyres.
Using snow chains
Using snow chains can help to improve traction in winter conditions. However, there are some restrictions you have to keep in mind.
Locations of cameras, sensors and radars
Knowing the placement of different components the car uses to map its surroundings helps you keep them free of dirt, obstructions and accidental damage.
