154 Starting and driving
Starting 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 starting
If 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
driving
The 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 revving faster than 6,200 rpm by
temporarily shutting of the fuel injec-
tors.
