Fuses
The fuses are housed in three fuse panels:
one behind a hatch on the left-hand end of
the fascia, one in the engine bay (additional
small unit in front of battery) and one on the
left-hand side of the trunk. There is space
for spare fuses in the hatch on the left-hand
end of the fascia.
To check if a fuse has blown, first remove it
from the panel. If the filament is broken, the
fuse has blown.
WARNING
To avoid the risk of short-circuiting and/or
fire breaking out in the electrical system,
the following should be heeded:
 Always consult an Saab dealer before
modifying or adding any electrical
equipment. Failure to do so can result
in the electrical system being
damaged.
 Never replace a fuse with one having
a higher rating than specified (see
page 201). The color of the fuse indi-
cates its amperage.
 If the same fuse blows repeatedly,
have the electrical system checked by
an Saab dealer.
 If a MAXI fuse blows, it means that
there is a major fault in the electrical
system. Have the car checked without
delay by an Saab dealer.
