Location

The engine compartment fuse box is mounted next to the battery on the left side of the engine bay. Unclip the plastic cover to reach the fuses and relays.

High-current maxi fuses protect major systems and should only be replaced with the engine off and the key removed. A blown maxi fuse often points to a wiring or component fault - have it diagnosed before fitting a new one. Fuse assignment varies by equipment level and production year. Always confirm with the label on the fuse box cover or the owner's manual.
