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
Changing a Fuse (page 111). Protected Component

CHANGING A FUSE
Fuses WARNING: Always replace a fuse
with one that has the specified
amperage rating. Using a fuse with a
higher amperage rating can cause severe
wire damage and could start a fire. If electrical components in the vehicle are
not working, a fuse may have blown. Blown
fuses are identified by a broken wire within
the fuse. Check the appropriate fuses
before replacing any electrical
components.
