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.

168 Starting and drivingRefueling1 Switch off the engine.
2 Open the filler cap, located in the right-
hand rear fender.
3 Insert the fuel pump nozzle beyond the
flange on the filler pipe and let the first
mark (a ring, a pimple or the first spring-
coil) rest on the flange. Do not withdraw
the nozzle while filling is in progress.
4 Cease refueling the first time the pump
stops, and wait a few seconds after
you´ve finished pumping before you
remove the nozzle.Filler cap
To remove the filler cap, turn it slowly to the
left (counterclockwise). The filler cap has a
spring in it; if you let go of the cap too soon,
it will spring back to the right.
When you put the filler cap back on, turn it
to the right (clockwise) until you hear three
clicks. Make sure you fully install the cap.
The most effective way to prevent conden-
sation forming in the tank (and thus avoid
possible running problems) is to keep the
tank full.
Refer to page 195 for information regarding
gasoline anti-freeze.
WARNING
If a fire starts while you are refueling, do
not remove the nozzle. Shut off the flow of
fuel by shutting off the pump or by notify-
ing the station attendant. Leave the area
immediately.
NOTICEDo not overfill. Fuel should not come right
up the filler pipe as expansion room is
needed when the temperature rises.
 Fill to maximum filling capacity.
 Stop filling after the first time that the
nozzle trips to shut off the flow of fuel.
 Filling capacity can differ between
different fuel stations and outside
temperature. Fuel tank volume when
nozzle trips to shut off, may vary by
0.5 gal. (2 liters).
 Do not fill fuel all the way up the filler
pipe. The gasoline must be allowed
room for expansion especially during
hot weather.

299 Technical data
Fuel
When to change engine oil.
Your vehicle has a display (SID) where time for service will be
shown. Based not only on mileage but also on driving condi-
tions the mileage at which a service will be indicated can vary
considerably.
Under normal circumstances the service indication will come on
at or around 15 000 miles or 2 years.
For this service system to work it is of outmost importance that
the right engine oil is used.
When the message for service is displayed you need to have
the required service done as soon as possible.
After the service your service personnel will reset the service in-
dicator. It is important to reset the service indicator in order to
optimize the time to the next service.

Gasoline with a lower octane rating can be used, although not
lower than AON 87. However, engine performance will fall slightly
and heavy loading and laboring should be avoided. For optimum
performance, use the recommended grade of fuel.
