Location

The engine compartment fuse box sits on the left side of the engine bay, next to the 12V auxiliary battery and the hybrid junction block. Unclip the cover latches and lift the lid straight up to reach the fuses and relays.

Several fuses here feed hybrid components (inverter, DC-DC converter, HV battery cooling pump). Disconnect the 12V battery before working near them and never touch the orange high-voltage cables. Fuse assignment varies by equipment level and production year. Always confirm with the label on the fuse box cover or the owner's manual.
