Maintenance and care
■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. (→P. 340)
●If the replaced fuse blows again, have the vehicle inspected by your
SUBARU dealer.
■If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
WARNING
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage, and possibly a fire or injury.
●Never use a fuse of a higher amperage rating than indicated, or use any
other object in place of a fuse.
●Always use a genuine SUBARU fuse or equivalent.
●Do not modify the fuse or the fuse box.
CAUTION
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your
SUBARU dealer.
