  WARNING:  Always disconnect the battery before servicing high current fuses.
  WARNING:  To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.

The power distribution box is in the engine compartment. It has high-current fuses that protect your vehicle's main electrical systems from overloads.
If the battery has been disconnected and reconnected, some features will need to be reset.

Passenger Compartment Fuse Panel


The fuse panel is in the right-hand side of the passenger footwell behind a trim panel. To remove the trim panel, pull it toward you and swing it away from the side. To reinstall it, line up the tabs with the grooves on the panel, and then push it shut.
Note: It may be easier to access the fuse panel if you remove the finish trim piece.
