Warning, charging
This light will come on together with if
the battery is discharging. If it comes on
while you are driving, stop the car as soon
as possible and switch off the engine.
Check the alternator drive belt (see page
202). If the belt has broken, the engine may
overheat (cooling system will not function
properly), the battery will not be charged,
the A/C compressor will not run and power
assistance for the steering will be lost.
Brake warning light
This light will come on together with if
there is insufficient brake fluid in the reser-
voir (see pages 198 / 198).
If the ABS warning light is on at the same
time, the ABS system may be inoperative
because of a fault (see ”Anti-lock brake
warning”, page 50).
Parking brake warning
light
This light will show when the parking brake
is on (see page 185).
If the car is driven with the parking brake still
on, will also come on and a chime will
sound.
The parking brake is mechanical and oper-
ates on the rear wheels.
WARNING
Never drive the car when these warning
lights are on. Danger of brake failure!
Have the brake system checked by an
authorized Saab dealer.
WARNING
 Always apply the parking brake when
parking, see page 185.
 Always apply the parking brake before
removing the ignition key.
 Do not apply the parking brake while
the car is moving.

72 Instruments and controls
Temperature control The cabin is divided into two temperature
zones:
 The driver’s zone.
 The passenger zone (front and rear
seats).
The desired temperature can be set
between 58 and 82°F (15 and 27°C). In
addition, there are also HI and LO settings
(see below). The HI and LO settings for the
passenger zone can only be selected if they
are also selected for the driver’s zone.
The displayed temperature is not the abso-
lute temperature but corresponds to the
comfort level normally experienced at that
temperature after allowance has been
made for the air flow, relative humidity, solar
radiation, etc., currently prevailing inside
the car.
 The most usual temperature setting is
64-76°F (18-24°C), depending on per-
sonal preference and what clothing is
worn.
 It is recommended that changes in the
temperature setting be made in steps of
2°F (1°C).
 Once the desired climate has been
achieved, the rear center vents can be
closed to prevent warm air being distrib-
uted at face height.Settings when HI selected:
 Maximum heat.
 Air distribution to windshield and floor.
 Recirculation OFF (even if manually
selected before).
 Fan: high speed.
 Settings shown on ACC display.
Settings when LO selected:
 Maximum cooling (A/C compressor will
run even if ECON manually selected
before).
 Air distribution through panel vents.
 Fan: maximum speed.
 Recirculation ON.
 Settings shown on ACC display.

FunctionsPressing AUTO will cancel all manual settings.
If a manual function is selected it will be locked in but other functions
will be controlled automatically.
The selected temperature is always maintained automatically.
Temperature, air distribution, fan speed and
recirculation will all be controlled automatically.
In falling temperatures the A/C compressor is
switched off at 32°F (0°C).
In rising temperatures the A/C compressor is
switched on at 41°F (+5°C).
If at the start the outside air temperature is 32 - 41°F
(0 – +5°C), the A/C compressor is switched off.
 Pressing AUTO once will cancel all previous
manual selections.
 Pressing AUTO a second time will result in all the
automatically selected settings being displayed. When the engine is started, the A/C system is in
AUTO mode, apart from any currently set program,
see page 76 and 77).

74 Instruments and controls
The rear-window and door-mirror heating is
controlled manually. Switch off the heating as soon as the rear window
is clear, to avoid imposing a heavy load on the bat-
tery longer than necessary. Note, however, that the
heating will go off automatically after 5-10 minutes
(depending on the outdoor temperature) or sooner
if the voltage in the electrical system falls below
10 V
.
The ACC system can be programmed to switch on
the heating automatically when the outdoor temper-
ature is below 41°F (+5°C) and the temperature
inside the car is below 50°F (+10°C) (see ”Program-
ming I and II”, on pages 76 and 77).
Recirculation is selected automatically for effective
cooling, but it can also be switched on/off manually.
Although recirculation does not substantially affect
the air quality, it is useful to prevent unpleasant
smells or fumes being drawn into the car from
outside.
IB373IB374
To increase the fan speed in steps.
If, after being off, the ignition is switched on but the
engine is not started, the fan will run at low speed
until the engine is running.
To decrease the fan speed in steps.
If the fan is set to 0, the A/C compressor will cut out
and ECON will appear on the display.
If, after being off, the ignition is switched on but the
engine is not started, the fan will run at low speed
until the engine is running.

152 Starting and driving
AON 93. One of the advantages of the
system is that it enables the engine to
be run safely on lower-grade fuel,
although not lower than AON 87.
 The maximum boost pressure is
adjusted automatically to the knocking
or pinging tendency of the engine.
Occasional, short-lived knocking when
the engine is under a heavy load is per-
fectly normal; the extent will depend on
the grade of fuel in the tank.
 Isolated instances of knocking are
more likely to occur with low-octane
fuel. This controlled form of knocking,
followed by a reduction in the boost
pressure, is a sign that the wastegate is
functioning and is perfectly safe for the
engine.
Important considerations with cata-
lytic convertersThe catalytic converter is an emission-con-
trol device incorporated in the car’s exhaust
system. It consists of a metal canister with a
honeycomb insert, the cells of which have
walls coated in a catalytic layer (mixture of
precious metals).
To ensure that the catalytic converter con-
tinues to function properly, and also to avoid
damage to the converter and its associated
components, the following points must be
observed:
 Have the car serviced regularly in accor-
dance with the service program. The fuel
and ignition systems are particularly
important in this context.
 Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to an authorized Saab
dealer as soon as possible.
 If the engine fails to start (in very cold
weather or if the battery is flat), the car can
be jump started (manual gearbox only) or
started using jump leads to a donor bat-
NOTEIf constant knocking occurs every time a
load is put on the engine, this indicates a
malfunction in the system.
Have the car checked without delay by an
authorized Saab dealer.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, to ensure
adequate cooling, air must be blown into
the engine compartment and under the
car at a rate equivalent to the ram-air
effect that would be obtained at the corre-
sponding road speed.
NOTEUse only unleaded gasoline. Leaded gas-
oline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

173 Starting and driving
Tire chainsIf you want to fit tire chains (where legally
permitted) they should only be fitted to the
tires recommended under ”Specifications”
(see page 257).
Consult your Saab dealer for details of
approved tire chains.
Driving in hot weather Always check the coolant level before
starting a journey. The level should be just
below the MAX mark.
 At the end of a journey, if the engine has
worked hard, allow it to idle for two or
three minutes before switching it off.
If the needle on the temperature gauge
enters the red zone:
1 Bring the car to a standstill but leave the
engine running. Do not remove the cap
on the expansion tank even if the tank is
empty. If the needle on the temperature
gauge continues to rise while the engine
is idling, switch off the engine. 2 Wait until the needle has dropped back
to indicate normal temperature (roughly
midway, in the white zone) before stop-
ping the engine. If the coolant needs top-
ping up, unscrew the cap on expansion
tank carefully.
Top up, as necessary, ideally with a
50/50 mixture of Saab-approved coolant
and water. If only water is available, use
that, but remember to have the coolant
mixture checked as soon as possible.
3 As soon as possible, have the cooling
system checked by an authorized Saab
dealer.
WARNING
 Do not exceed 30 mph (50 km/h)
when tire chains are fitted.
 Tire chains can reduce the directional
stability of the car.
 Tire chains must not be used on the
rear wheels. NOTE Check the links frequently for wear.
 Check that the chains do not contact
the wheel-arch liner at full lock.
 See section ”Specifications”, page
257, for information on allowable
wheel dimensions for the fitting of tire
chains.
WARNING
Always undo the expansion tank filler cap
carefully, releasing the pressure and any
vapor before removing the cap com-
pletely.
