184 Car careBattery disconnect switchA crash could cause a short circuit in the
alternator or starter motor. A disconnect
switch by the battery’s positive terminal cuts
off the battery from the alternator and starter
motor when the airbags and seatbelt pre-
tensioners are detonated.
WARNING
If the battery disconnect switch has
tripped, do not reset it until you have visu-
ally inspected the car’s electrical system.
If there are visible signs of damage, have
the car checked at a Saab dealer before
resetting the disconnect switch.NOTICEExercise special care when removing and
fitting the positive (+) cable so as not to
damage the battery disconnect switch.

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:
 insufficient engine cooling
 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.NOTICESerious damage can be done to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.
