matic closing does not work or if the battery
has been disconnected. The pinch protec-
tion will not work if the windows are not
calibrated.
Perform calibration as follows:
1 Make sure the soft top is raised.
2 Make sure the doors are closed.
3 Let the engine idle.
4 Press and hold the soft top button up
until a chime sounds.
During calibration, the four windows will
be raised and lowered several times.
If calibration fails twice in a row, have the car
checked and rectified. We recommend that
you contact a Saab dealer.
Interior lightingThe interior lighting consists of a front roof
light, two front reading lights, footwell light-
ing and courtesy lighting in the doors. The
light switches are located in the roof con-
sole.
The cabin lighting comes on:
 When a door is opened and the ignition is
OFF.
 When the remote control is removed from
the ignition switch.
The lighting goes out:
 When the car is locked.
 When the ignition is turned on.
 Approx. 20 s after closing all doors.
The lights are dimmed out gradually.
If a door is left open with the ignition OFF,
the interior lighting goes out automatically
after 5 min so as not to drain the battery.

86 Instruments and controlsThis light shows when the high beam is on
(see page 103).
This light indicates when the front fog lights
are on (see page 104).
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 224).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 224).
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 workshop to have the
brake system checked. We recommend
that you contact a Saab dealer.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
following message will appear on the Saab
Information Display (SID):
If this is the case, drive carefully and contact
a workshop as soon as possible. We recom-
mend that you contact a Saab dealer. Refer

164 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. We
recommend that you 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 boost pressure
 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. However, engine perfor-
mance will fall slightly and heavy load-
ing and laboring should be avoided. For
optimum performance, use the recom-
mended 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 working
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. We recommend that you
contact a Saab dealer immediately.
 The use of fuel with too low an octane
rating can cause serious engine
damage.

165 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 85). Have the car checked at a work-
shop as soon as possible. We recommend
that you contact a Saab dealer.
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 accor-
dance 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 workshop. We
recommend that you contact 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. We
recommend that you contact a Saab
dealer for advice.
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. We recommend that
you contact 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.

194 Starting and drivingengine wear is at its greatest during this
period. Drive off as soon as possible after
starting the engine and avoid high engine
speeds.
 Drive as smoothly and thoughtfully as
possible. Match your driving to the prevail-
ing traffic conditions.
 Driving in a low gear gives rise to higher
fuel consumption than driving in a high
gear because of the higher engine speed
for any given road speed. Always shift up
as soon as traffic conditions allow and
drive in the highest gear as much as
possible.
 Check the tire pressure once a month.
Incorrect tire pressure increases tire
wear. It is preferable for the tire pressure
to be slightly high than too low. Under-
pressure increases fuel consumption. Check the fuel consumption regularly.
Increased fuel consumption can indicate
that something is wrong and that the car
needs to be checked. We recommend
that you contact a Saab dealer.
Practical road tests have demonstrated that
substantial savings in fuel consumption can
be made if the above advice is followed.
Road conditionsWet roads increase fuel consumption, as do
unpaved roads and driving in hilly country
(the amount of fuel saved driving downhill is
less than the additional amount required to
climb the hill).
Engine block heater3The following are just some of the benefits
to the car and the environment of using an
engine block heater:
 Lower fuel consumption.
 Reduced wear on the engine.
 Inside of car warms up faster.
 Exhaust emissions substantially reduced
over short runs.
The engine heater is effective at outside
temperatures up to 60–70°F (+15–+20°C).
The warmer it is outside, the shorter the time
the engine heater needs to be connected.
Longer than 1.5 hours is unnecessary.
If the car is equipped with a removable,
electric cabin heater that is not in use, store
this in the trunk.
WARNING
Never switch off the engine while driving
as the effect of the brakes and power
steering will be greatly reduced.
