76 Instruments and controlsThis light shows when the high beam is on
(see page 92).
This light indicates when the front fog lights
are on (see page 93).
The front fog lights are switched off auto-
matically when the engine is switched off.
When the fog lights are next needed, they
will have to be switched on manually.This light should come on briefly when you
turn the ignition key to ON. If it doesn´t come
on, have it fixed so it will be ready to warn
you if there is a problem. This light indicates
when the brake fluid level is too low (see
page 200).
The following message is shown on the
Saab Information Display (SID):For safety reasons, stop the car and check
the level of the brake fluid (see page 200).
If the level is normal, depress the brake
pedal firmly two or three times. Now check
the level again. If the level is still normal, you
may drive the car, with considerable cau-
tion, to the nearest Saab dealer to have the
brake system checked.
The brake system provides Electronic
Brakeforce Distribution (EBD). This distrib-
utes the brake pressure between the front
and rear wheels, in such a way as to achieve
optimum braking performance irrespective
of the car’s load.
If a fault arises in the EBD function, the ,
and lights will come on. Also, the fol-
lowing message will appear on the Saab
Information Display (SID):
If this is the case, drive carefully and contact
a Saab dealer as soon as possible. Refer to

80 Instruments and controlsTemperature gaugeThe temperature gauge shows the temper-
ature of the coolant. The needle should be
in the middle of the scale when the engine
is at normal operating temperature.
If the needle goes into the red zone (which
can occur at high outside air temperatures
or under heavy engine loads), choose the
highest possible gear ratio and the lowest
possible engine speed, and avoid shifting
down.If the needle repeatedly enters the red zone,
stop the car as soon as it is safe to do so and
check the coolant level (see page 199).
Turbo gaugeThe turbo gauge indicates the air volume
used for combustion, which is equivalent to
the engine load.
At low loads and when the engine is used for
braking, the needle will move within the
white zone.
Under certain barometric conditions the
needle may enter the first part of the red
zone without necessarily indicating that a
fault has arisen.
NOTICEIf the needle, despite the above action,
enters the red zone, stop the car in a suit-
able place and allow the engine to idle. If
the needle continues to rise, switch off the
engine.
WARNING
Never open the cap of the expansion tank
completely when the engine is hot, open
with care. The pressure in the cooling-
system can cause hot coolant and steam
to be released. Failure to heed this warn-
ing may result in personal injury.

144 Starting and drivingImportant
considerations for
driving1 Starting and driving
 Do not use full throttle until the engine
is warm, so as to avoid unnecessary
wear. If the needle of the turbo gauge
repeatedly enters the red zone, the
engine may suddenly lose power, due
to the initiation of a monitoring system
that limits the boost pressure. Contact
a Saab dealer as soon as possible.
 Under certain barometric conditions
(high outside temperature and/or high
altitude) the needle may enter the first
part of the red zone without necessarily
indicating that a fault has arisen.
 A protective function (interruption of the
fuel supply) limits the engine speed.2 Stopping the engine
 Do not rev the engine immediately
before switching it off - stop the engine
when it is idling.
3 Regulating the charging pressure
 The system is optimized for AON 90.
One of the advantages of boost pres-
sure regulation is that the engine can
also be run safely on gasoline with a
lower octane rating, although not lower
than AON 87. Severe engine damage
will occur if gasoline lower than 87
octane is used. However, engine
performance will fall slightly and heavy
loading and laboring should be
avoided. For optimum performance,
use the recommended grade of fuel.
 The maximum boost pressure is regu-
lated according to the tendency of the
engine to knock. Short-lived knocking
is perfectly normal. This can occur
when the engine is running at about
3,000 rpm under a heavy load. The
extent of this knocking will depend on
the grade of fuel in the tank.
 Isolated instances of knocking can
occur with low-octane fuel. This
controlled form of knocking, followed
by a reduction in the boost pressure, is
a sign that the control system is work-
ing normally, and is perfectly safe for
the engine.
Limp-homeThe engine management system has a
diagnostic feature that checks a number of
internal functions. If a fault is detected in the
throttle valve, the engine management
system will set the throttle system to the
limp-home mode. This means:
 idling control will be poor (uneven idling
since regulated by ignition and fuel
supply)
 engine performance will be reduced
 the cruise control will not function
 the capacity of the A/C compressor will be
limited.NOTICE If the engine sounds strange there is a
malfunction. Contact a Saab dealer
immediately.
 The use of fuel with too low an octane
rating can cause serious engine
damage.
ProCarManuals.com

145 Starting and driving
If the diagnosis function detects a fault in the
engine management system, the light
"Engine malfunction (CHECK ENGINE)" in
the instrument panel will come on (see page
75). Have the car checked at a Saab dealer
as soon as possible.
The following message is shown on the SID:
Important considerations with
catalytic 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 (precious
metal alloy).
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 accord-
ance with the service program.
 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 a Saab dealer.
 If the engine fails to start (in severe cold
or if the battery is flat), the car can be
bump started (manual transmission only)
or started using jump leads to a donor
battery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
it to idle for up to 5 minutes to give it time
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
switch off the engine to avoid serious
damage to the catalytic converter.
Contact a Saab dealer for advice. Reduced engine power.
Contact Saab dealer.
NOTICEIf "Engine malfunction (CHECK
ENGINE)" warning light starts to flash
(indicating that the engine is misfiring and
the catalytic converter can be damaged),
ease off the accelerator slightly. The light
should go out or start to shine constantly.
If the light continues to flash despite
easing off the accelerator, you may
continue to drive the car but at the mini-
mum throttle permitted by the current traf-
fic situation. Have the car checked as
soon as possible at a Saab dealer.
NOTICEUse only unleaded gasoline. Leaded
gasoline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.
