Smart warranty package with used Smart

Hello everyone, I bought on 24.02 a used smart from a dealer who is about 1.5 St from my place of residence. When I signed the contract, I asked if I could go for repairs within the warranty to any branch in my place of residence and he had confirmed that. Now I noticed some lack (the switch for the outer mirror does not work and the switch for the volume when turning up decreases by a few “points” the volume st he said that the guarantee would not cover it and that I should go to it because it could only be made out of culant. Is that right? WTF covers the guarantee? Of course, the link on the official website, if you want to look at the conditions, will take you to a beautiful error 404. Thanks in advance! If you want to get a look at the conditions, you can get a look at them.
