If any electrical device on board is not working, the first thing to check is the integrity of the relevant protective fuse: it must be replaced with one of the same rating and never with a larger one, which could cause irreparable damage to the device itself.

In the case of the Smart Forfour, the fuse box is located inside the cabin, on the driver's side, at the bottom left of the dashboard.

Once you remove the cover, you can also read the legend that associates each relay and fuse, appropriately numbered, with the component it powers and protects.
