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.
Replace fuses with the same type and
rating. See Changing a Fuse (page 335). Protected Component
