38 SecurityLocking by key (1)
Turn the key clockwise: all doors and trunk
lid locked.
The trunk lid cannot be opened now from
inside using the switch on the driver’s door.
Unlocking by key (2)
Turn the key counterclockwise once: the
driver´s door unlocked.
Turn the key counterclockwise twice: all
doors, but not trunk lid, unlocked.The central locking can also be operated
from inside the car by means of the
switch on the center console (except on
Convertibles).
To lock all doors: press the symbol side of
the switch once.
To unlock the driver´s door: press the
switch once.
To unlock all doors: press the switch
twice.
This switch is inoperative when the car is
locked from the outside.The interior locking buttons on each door
affect only the respective door on sedan.
The driver´s door lock button will
lock/unlock both on the Convertible.
If the car is left with the doors open, the inte-
rior lighting will be switched off automati-
cally after 20 minutes, to prevent a dead
battery.
WARNING
Having the doors locked when you are
driving will reduce the likelihood of:
Children, in particular, opening doors
and falling out of the car.
Intruders entering the car when it is
moving slowly or at a standstill.
Injury resulting from a door bursting
open in the event of a crash.
However, you must also remember that
locked doors can hamper rescuers in the
event of a crash.

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 fuel with an
octane rating of AON 90. For cars with
205 hp engines and the Viggen, the
system is optimized for 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. However, engine perfor-
mance will fall off slightly, and heavy
loading should be avoided. For best
performance you should use the rec-
ommended grade of fuel, AON 90
(205 hp engine and Viggen AON 93).
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.Saab 9-3 Viggen: The Saab 9-3 Viggen has
a high-performance engine which means
that a certain amount of care should be
exercised, in particular when accelerating in
the lower gears. This is especially important
when the road surface is slippery to avoid
the driving wheels from losing their grip.
Limp-homeThe car’s engine management system has
a diagnostics function that, once the engine
has been switched off, checks a number of
internal functions. If a throttle valve fault is
detected, the engine management system
will initiate limp-home mode for the valve.
This means, for example, that idling speed
regulation will be impaired, the cruise con-
trol system will be inoperative, and the
capacity of the A/C compressor will be lim-
ited.
When starting the car in limp-home mode at
temperatures below 32°F (0°C), depress
the accelerator slightly.
If the diagnosis function detects any faults in
the engine management system, the
“Engine malfunction (CHECK ENGINE)
“ indicator in the main instrument panel
will light up (see page 63). The car should
be checked as soon as possible at an
authorized Saab dealer.
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. NOTEIf the engine is being run with the car on a
rolling road or dynamometer, longer than
for a standard state emission inspection,
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 corresponding road speed.
