Fuse box in engine compartment
The engine compartment fuses are located under the engine cover on the driver’s side, between the brake master cylinder and the left front wing.
To remove the cover, squeeze the tabs at the front of the fuse box. Then lift the cover up next to the tabs. The cover will slide off the top of the fuse box. To replace the cover, place the two hinge-shaped tabs on the back of the cover under the tabs on the fuse box. Press the front of the cover down until the front tabs snap into place.

The fuses for the relay control module are located in the control module box next to the battery in the engine compartment.
Passenger compartment fuse box
The access door is located at the end of the instrument panel on the driver’s side, behind the trim panel cover.
Use a flathead screwdriver or coin to open and close this access door.
