What is covered by the liability reduction?

Limitation of liability protects you in the event of accident damage or theft of the vehicle.

It is included in your rental cost and limits your financial responsibility (also known as "deductible") should something go wrong. This reduces your financial excess depending on the protection you choose, from CHF 0 to CHF 3000 in case of theft and damage to the vehicle, its parts and accessories, provided the vehicle is used in accordance with the terms of the rental contract. 
The liability reduction does not cover negligence, interior damage, damage to the underbody or roof.
