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. (oP. 380)
●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.

5-2. Steps to take in an emergency
If the engine will not star t
If the engine will not start even though correct starting procedures
are being followed (oP. 169, 178), consider each of the following
points.
■The engine will not start even when the starter motor oper-
ates normally.
One of the following may be the cause of the problem.
●There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
●The engine may be flooded.
Try to restart the engine once more following correct starting
procedures. (oP. 169, 178)
●There may be a malfunction in the engine immobilizer system.
(oP. 80)
■The starter motor turns over slowly, the interior lights and
headlights are dim, or the horn does not sound or sounds at
a low volume.
One of the following may be the cause of the problem.
●The battery may be discharged. (oP. 453)
●The battery terminal connections may be loose or corroded.
■The starter motor does not turn over. (vehicles with a key-
less access with push button start system)
The engine starting system may be malfunctioning due to an
electrical problem such as an open circuit or a blown fuse. How-
ever, an interim measure is available to start the engine.
