Main fuse box
The main fuses are designed to melt during an over-
load to prevent damage to the wiring harness and
electrical equipment. Check the main fuses if any
electrical component fails to operate (except the
starter motor) and other fuses are good. A melted
main fuse must be replaced. Use only replacementswith the same specified rating as the melted main
fuse. If a main fuse blows after it is replaced, have
the electrical system checked by your nearest
SUBARU dealer.
