Location

The fuse/relay box is in the engine compartment, next to the battery on the left side. Unclip and lift the plastic cover to access the fuses and relays.

Use a fuse puller when available and always replace with the same amperage. The dashboard holds a separate interior fuse box. Fuse assignment varies by equipment level and production year. Always confirm with the label on the fuse box cover or the owner's manual.
