Learn about Citroën C5 2008-2017 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Citroën C5 (2008-2017) is offered in both sedan and estate (Tourer) body styles, each known for its sleek design and spacious interior. These models emphasize comfort, with Citroën’s signature Hydractive suspension and advanced driving aids. However, the vehicle’s electrical system, including the fuse box and relays, plays a crucial role in maintaining its smooth operation.
The fuse box, typically located under the dashboard and in the engine compartment, houses essential fuses for components such as the headlights, air conditioning, and infotainment system. Relays, essential for switching high-current circuits, are integral to functions like the fuel pump and wipers, making them critical for the C5’s reliability. Proper maintenance and occasional checks on these electrical components are essential for ensuring consistent performance.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
