1. Locate the fuse box. It is located in the engine compartment, on the passenger side near the top of the engine. It has a black cover with the word "Fuses" printed on it.
2. Press the release levers. There are two levers, one on each side of the fuse box cover. Press both of these levers at the same time.
3. Lift the cover. The fuse box cover will lift up and you will be able to access the fuses inside.
Please note that the location and appearance of the fuse box may vary slightly depending on the specific model and year of your Renault Scenic. If you are unable to locate or open the fuse box, it is best to consult your vehicle's owner's manual for specific instructions.
