1. Open the fuse box. In the Peugeot 206, the fuse box is located on the driver's side of the dashboard, behind a small cover near the steering wheel.
2. Once you've opened the fuse box, you'll see a diagram that shows the location of each fuse. The fuse for the instrument panel lights is usually labeled as "Instrument Panel" or "Dashboard Lights."
3. Check the fuse to see if it's blown. A blown fuse will have a broken filament, which you can easily see by holding the fuse up to a light source.
4. If the fuse is blown, replace it with a new fuse of the same amperage. Be sure to use the correct type of fuse, as using the wrong type of fuse could cause damage to your car's electrical system.
