■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. 401)
● 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.

BRZ_U
If the engine will not start
If the engine will not start even though correct starting procedures
are being followed ( →P. 172, 182), 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. ( →P. 172, 182)
● There may be a malfunction in the engine immobilizer system.
(→ P. 82)
■ 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. ( →P. 476)
● 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.
