Drive beltThe alternator is situated on the right-hand
side of the engine. It is driven by a
poly-V-belt from the crankshaft pulley.A slipping or broken poly-V-belt can
result in:
no charge to the battery
no A/C compressor function.
The belt tension is critical and is adjusted
automatically by the belt tensioner.
WARNING
Keep hands and clothing clear of drive
belts when engine is running.
Always stop the engine before
inspecting the drive belt.
The radiator fan is electric and can
start even when the engine is
switched off.NOTESerious damage can be done to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.

Fuses
The fuses are housed in three fuse panels:
one behind a hatch on the left-hand end of
the dash, 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 dash.
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:
We recommend that you always con-
sult an Saab dealer before modifying
or adding any electrical equipment.
Failure to do so can result in the elec-
trical system being damaged.
Never replace a fuse with one having
a higher rating than specified (see
page 239). The color of the fuse indi-
cates its amperage.
If the same fuse blows repeatedly,
have the electrical system checked by
a workshop. We recommend that you
contact a 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. We recommend that you con-
tact a Saab dealer.

257 Car care
Winter tiresWinter (snow) tires are recommended for
winter climates where the majority of your
driving will be done on snow and ice. Winter
tires should be fitted to all four wheels to
maintain a proper balance. Your Saab
dealer can advise you of to the correct size
tire for your car (if different from the original
size) and also supply Saab approved winter
tires pre-mounted on steel or alloy rims.
Winter tires normally use a different speed
rating compared to summer/all season tires.
Make sure not to exceed the stated speed
rating on the tires you use.
Make sure that wheels with sensors for tire
pressure monitoring are fitted during
replacement if the car has automatic tire
pressure monitoring.Tire date codeTires should be regarded as perishable
goods. As the tires age, the rubber becomes
progressively harder, and the roadholding
ability of the tires diminishes. This is partic-
ularly true on winter tires.
Tires have a code that specifies their date of
manufacture. The first two digits denote the
week number and the last two digits the year
followed by a filled triangle.
Automatic tire pressure
monitoring systemThe system consists of a sensor in each
wheel and a receiver. The sensors are
located inside the tire in direct connection
with the air pressure valves.
Make sure that wheels with sensors for tire
pressure monitoring are fitted during
replacement if the car has automatic tire
pressure monitoring.Tire pressure information is transmitted
wirelessly to the receiver.
The system checks the tire pressures when
speed exceeds 19 mph (30 km/h).
The system is self-programming which
means that the wheels can be shifted
around without any need for adjustment.
The spare wheel has no sensor. The system
will trigger a warning/alarm because of that.
The sensor batteries last for 10 years or
around 160 000 km. The battery cannot be
replaced. The whole sensor must be
replaced.
WARNING
The system is an aid to the driver. The
driver always has the responsibility that
the tires have the correct air pressure.
For optimum safety, economy and com-
fort tire pressures should be checked reg-
ularly even if the automatic tire pressure
monitoring has not alarmed.
NOTETire replacement must take place with
great care to avoid damaging the sensors
that are built together with the valves.
Remove the rear side first.
Start to remove the tire opposite the
valve.
During removal the tire machine must
not come closer than ±10° from the
valve.
During fitting, start 20° after the valve
and finish 20° before the valve.
Do not inflate the tire with pressure
higher than 102 psi (700 kPa).

Gasoline with a lower octane rating can be used, although not
lower than AON 87. However, engine performance will fall slightly
and heavy loading and laboring should be avoided. For optimum
