Passenger Compartment Fuse Box
WARNING: Always disconnect the
battery before servicing high current
fuses.
Note: If your vehicle has dual batteries,
disconnecting the primary under-hood
battery does not remove power from all
circuits. This fuse panel is below and to the
left-hand side of the steering wheel near
the brake pedal. Remove the panel cover
to access the fuses.
To remove a fuse, use the fuse panel
cover's fuse puller tool.
Replace fuses with the same type and
rating. See
