onds, while the SID checks are being per-
formed.
When a CHECK message is generated
while the car is being driven, a chime will
sound, INFO DISPL will illuminate on the
main instrument panel, and the message
will appear on the SID. The number of mes-
sages that can be displayed by the SID
varies with the specification of the car.
If more than one CHECK message has
been generated, the
+ symbol will appear to
the left of the text on the display. The mes-
sages appear in order of priority.

The following CHECK messages may be
displayed: 1) This message will be displayed approximately
600 miles (1,000 km) before the next sched-
uled service is due, or when 365 days have
elapsed since the last service. The message
should be cleared at the time of that service
(see the Saab Warranties & Service Record
Booklet).
This message can also be deleted by first
briefly pressing the CLR button, then depress-
ing it a second time for at least eight seconds
until "SERVICE" appears on the display and a
chime sounds. The message can only be
deleted when it is shown on the SID.
Night panelTo improve night-driving conditions inside
the car, the Night Panel mode can be
selected. In this mode, the amount of infor-
mation displayed is reduced, and only the
most important instruments and displays
will be illuminated.
When the Night Panel button is pressed,
only the speedometer will be illuminated (up
to the 87-mph or 140-km/h graduation), all
the other instruments illumination will be
extinguished and their needles moved to
zero. Both the SID and the ACC displays will
be extinguished and the backlighting for
switches and other controls will be dimmed.
Note: All indicator and warning lights,
together with the display of CHECK mes-
sages, will operate as normal. The following conditions will wake up the
respective displays in the Night-Panel
mode:
 Setting of the Audio System, SID or ACC
(display comes on for ten seconds).
 CHECK message generated in the SID.
 High engine revs cause the rev counter to
be illuminated until the engine speed has
fallen again.
 If the quantity of fuel remaining falls below
4 gallons (15 liters), the fuel gauge will be
illuminated.
 If the engine temperature rises above nor-
mal, the temperature gauge will be illumi-
nated.
 If the speed of the car exceeds 84 mph
(135 km/h), the entire speedometer will
be illuminated.

Programming II It is also possible to customize the ACC system to adapt to driving
and weather conditions. Programming and cancellation of programming is carried out by
holding the appropriate button down until the corresponding symbol
has flashed 4 times, an audible signal has sounded and the follow-
ing text for the desired function has appeared in the SID.
Make sure the ignition is ON.
Example:
If you want to control the switching on and off of the heating for the
rear window and the door mirrors manually, hold the button
depressed until the symbol has flashed 4 times, an audible signal
has sounded and the following text has appeared in the SID.

SID shows:
ACC: MANUAL
RDEFR CTRL
Once a function has been recorded under ”Programming II”, it will
remain in the system until you cancel the program.
AUTO will still show on the display after a function has been saved
in ”Programming II”.
Additional programming features, see page 245. Function Operation in AUTO mode
after Programming II Standard operation in
AUTO mode
The A/C compressor is not
switched on until the out-
side temperature goes
above +55°F (+13°C).
– This function can be used
to save fuel, since the A/C
compressor will not be in
action for so long a time.
In wet weather, however,
the A/C compressor should
be on at below 57
°F (14°C)
as well, since this reduces
the risk of misting on the
windows.
A/C compressor cuts in
when outside tempera-
ture is above 32°F
(0°C).
Rear-window heating can
only be switched on manu-
ally. The heating will come on
about five seconds after
the engine has started if
the outside temperature
is below +41°F (+5°C).–The activation time
depends on the outside
temperature.

92 Instruments and controlsUseful tips: If the ACC system is not functioning
satisfactorily the following should be tried
before you take the car to an authorized
Saab dealer.
 If the indication AUTO does not light up
after starting (the ignition must have been
switched off for at least 10 minutes): See
“Cancelling program I”, page 90.
 If you think that the ACC system is not
functioning satisfactorily you should:
1 Check that the cigarette lighter plug is in
its socket (since if the socket is empty
heated air can flow out and affect the
cabin sensor).
2 Recalibrate: See the section headed
Calibration, page 90.
 If the battery has been disconnected or
has died, the ACC system should be reca-
librated: See Calibration, pag 90.
Programmed settings are not deleted if the
battery has been disconnected. Extinguishing the lighting in ACC See section Night panel, page 73.
ACC - 9-3 Convertible When the soft top is folded down the ACC
system goes over to manual temperature
setting.
Between HI and LO there are eleven (0-10)
fixed temperature steps.
The system adjusts itself as follows:
 AUTO is turned off.
 Heating, air distribution and fan speed are
not affected.
 Recirculation and electric rear window
are turned off.
 A/C assumes the same setting (ON/OFF)
as it had when the soft top was last folded
down.
All manual selections are possible with the
exception of electric rear window.
Saab recommends leaving the ACC setting
on ECON when the soft top is folded down
to improve fuel economy and unnecessary
running of the A/C compressor.
When the soft top is raised the system
reverts to the AUTO mode and the previous
set temperature.
Fault diagnosis and care of A/C sys-
tem, see page 226.

the central locking system) does not unlock,
proceed as follows.
Check fuse 25. If it is blown or its replace-
ment blows, you can release the lock motor
from the door as follows:
1 Use a sharp knife to release the pre-cut
rectangle on the right in the upholstery in
the trunk so that you can access the two
retaining screws that secure the lock
motor to the fuel filler door.
2 Unscrew the retaining screws some-
what and back them out through the
screw holes, whereupon the lock motor
will be released from the door.
Have an authorized Saab dealer investigate
the problem.

148 Starting and drivingStarting the engine The engine has an automatic choke and
should be started as follows:
Cars with manual gearbox
To start the engine the clutch pedal must
be fully depressed.
1 Depress the clutch pedal but do not
touch the accelerator.
2 Start the engine. Let the ignition key
spring back as soon as the engine has
started and is running smoothly – at very
low temperatures, you may need to run
the starter for up to 50 seconds.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least
2-3 minutes after starting.
Cars with automatic transmission
The selector lever must be in the P or N
position.
1 Keep your foot on the brake pedal.
2 Start the engine. Let the ignition key
spring back as soon as the engine has
started and is running smoothly – at very
low temperatures, you may need to run
the starter for up to 50 seconds.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least
2–3 minutes after starting.
Useful tips on cold climate startingIf the engine has failed to start after several
attempts in very cold weather, press and
hold the accelerator down to the floor and
run the starter for 5–10 seconds. This will
prevent the engine being flooded (exces-
sively rich fuel-air mixture).
Now start the engine in the normal way – do
not touch the accelerator.
If the engine stalls immediately after starting
(e.g. if the clutch was released too quickly),
do not touch the accelerator when restarting
the engine.
Every time the engine is switched off the
spark plugs are automatically cleaned. If
your attempt to start nevertheless fails, let
go of the ignition key and allow it to spring
back. This initiates more vigorous cleaning
of the sparking plugs which goes on for
about 5 seconds. Then start in the ordinary
way. Do not touch the accelerator; if the
accelerator is pressed to the floor the fuel
supply is shut off.
Important
considerations for
drivingThe engine-management system in the
Saab 9-3 is called Saab Trionic T7. The
system manages the ignition, fuel injection
and turbo boost pressure.
The Trionic T7 system developed by Saab
is an intelligent engine-management
system designed to achieve optimum drive-
ability under differing driving conditions.
The system makes adjustments automati-
cally, for instance, if the car is being driven
at altitude (oxygen-deficient air), for differ-
ent grades of fuel (AON 87–93) and for dif-
ferent load conditions.
1 Starting and driving
 Refrain from using full throttle before
the engine has warmed up (before
needle is in the mid-range on tempera-
ture gauge) to avoid unnecessary
wear. If the needle of the pressure
gauge repeatedly enters the red zone
the engine may suddenly lose power,
owing to the intervention of a monitor-
ing system which curtails the charging
pressure. Get in touch with an autho-
rized Saab dealer at once.
 A safety function prevents the engine
from reving faster than 6,200 rpm by
temporarily shutting of the fuel injec-
tors.
ProCarManuals.com

149 Starting and driving
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.
