light and alarm:
 Airbag system.
 Low oil pressure in engine.
 Parking brake is on (when car is moving).
 Brake fluid level low.
 Fault detected in ABS system.
 Electronic brake force distribution (distri-
bution of brake pressure between front
and rear wheels).
 Engine overheating.

Engine malfunction
(CHECK ENGINE)
This light indicates a malfunction in the
fuel-injection or ignition system. The car
may still be driven with care and with some-
what diminished performance (see page
149).
Indicator, fuel
This light comes on when there is less than
about 2.5 gallons (10 liters) of fuel left in the

WARNING
An illuminated ”Engine malfunction
(CHECK ENGINE)” indicator light indi-
cates a serious engine-related problem.
While your car may be able to be driven
with the ”Engine malfunction (CHECK
ENGINE)” indicator light illuminated
(Limp-home mode), you are advised to
have your car serviced at an authorized
Saab dealer as soon as possible.
Continued driving without this problem
being corrected might cause serious
further damage to your car and create
unsafe driving conditions. The operator
should be prepared to take action if such
unsafe conditions arise (e.g., apply the
brakes, disengage transmission, turn off
the ignition etc.).
NOTEThe car should be checked immediately
at an authorized Saab dealer to prevent
more serious faults from arising.NOTEIf the car runs out of fuel, air can be drawn
in with the fuel, which, in turn, can cause
the catalytic converter to be damaged by
overheating.

200 Car care and technical informationCharging/replacing the batteryConnect the positive lead to the positive (+)
battery terminal (red), and the negative lead
to a good ground point, e.g. the lifting lug at
the front of the engine.
To remove the battery, always disconnect
the negative (black) lead first and reconnect
it last when fitting the new battery.
The battery size must comply with DIN
53735 MFI 230/2.16.

NOTETo avert the danger of short-circuiting
between the positive (+) terminal on the
battery and the inlet manifold on the
engine, always disconnect the negative
(-) battery lead first and reconnect it last.
NOTE Never reverse the polarity of the bat-
tery by connecting the leads to the
wrong terminals. The red, positive
lead connects to the positive (+) termi-
nal, and the black, negative lead to the
negative (-) terminal.
 Serious damage can be done to the
car’s electrical system if a battery or
alternator lead is disconnected while
the engine is running.
 The nut on the battery clamp should
be tightened to a torque of 10 Nm.

201 Car care and technical information
Drive belts The alternator is situated on the right-hand
side of the engine, adjacent to the bulkhead.
It is driven via a Poly-V-belt from the crank-
shaft pulley.
The Poly-V-belt also drives the water pump,
the A/C compressor and the steering servo
pump.
The belt tension is critical and is adjusted
automatically by the belt tensioner.
See also page 51, ”Warning, charging”.
WARNING
 Keep hands and clothing well clear of
drive belts when engine is running.
 Always stop engine before inspecting
drive belts.
 The fan 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.
