Warning and
indicator lightsA number of warning and indicator lights will
come on when the ignition is switched on
prior to starting (see page 58). Under
normal conditions, these should go out a
few seconds after the engine has started.
Warning, oil pressure (en-
gine oil)
This symbol comes on together with if
the oil pressure in the engine is too low. If
the symbol flashes or comes on while you
are driving, stop as soon as possible and
where it is safe to do so, switch off the
engine and check the engine oil level, see
page 172. NOTEThe car must not be driven under any cir-
cumstances when the warning lamp is on.
Too low oil pressure will damage the
engine.

Central warning light
This light comes on and a chime will sound
if a fault has been detected in any system
that is critical to safety. Any of the following
can activate the central warning light and
alarm:
 Airbag system.
 Low oil pressure in engine.
 Parking brake is on (when car is moving).
 Brake fluid level low.
 Fault detected in ABS system.
 Engine overheating.
 Alternator not charging properly.
The symbol and the chime will also sound if
the ignition key is turned to the ON position
but the engine is not started within 10 sec-
onds.
Cruise Control
indicator light
The symbol is lit when cruise control is
active.
Engine malfunction
(CHECK ENGINE)
This light indicates a malfunction in the
fuel-injection or ignition system. The car
may still be driven with care and with some-
what diminished performance.
SPORT Mode Indicator
On cars with automatic transmission the
indicator light comes on when you press the
SPORT button on the gear-lever knob.
In SPORT mode, the transmission remains
longer in the (D, 3, 2, 1) gears before
upshifting.
Quit Sport mode by again depressing the
SPORT button; see also page 147.
WINTER Mode Indicator
On cars with automatic transmission the
indicator light comes on when, in the D posi-
tion, you press the WINTER button on the
center console next to the gear selector.
When the car is in the Winter mode it starts
in 3rd gear, which gives a better grip in
slippery conditions by reducing the ten-
dency to spin the wheels.
Quit Winter mode by again depressing the
WINTER button; see also page 147.
WARNING
An illuminated CHECK ENGINE indicator
light indicates a serious engine-related
problem. While your car may be able to be
driven with the CHECK ENGINE indicator
light illuminated (limp-home mode), you
are advised to have your car serviced at
an authorized Saab dealer as soon as
possible.
Continued driving without this problem
being corrected might cause serious fur-
ther damage to your car and create
unsafe driving conditions. The operator
should be prepared to take action if such
unsafe conditions arise (e.g., apply the
brakes, disengage transmission, turn off
the ignition etc.).

61 Instruments and controls
Under certain barometric conditions the
needle may enter the first part of the red
zone without necessarily indicating that a
fault has arisen.
If the needle repeatedly enters the red zone
and the engine at the same time loses
power, because the monitoring system is
holding the charging pressure down, you
should contact an authorized Saab dealer.
If the speed exceeds 143 mph (230 km/h),
the increase in speed will be limited by the
lowering of the boost pressure. The pres-
sure gauge then moves towards the middle
of the orange zone, indicating reduced
engine output and thus reduces the speed
of the car as well.
Fuel gaugeThe fuel-tank capacity is 17.0 gal. (64 liters).
The fuel gauge shows the amount of fuel left
in the tank. When this is down to about
2.5 gal. (10 liters), a warning light on the
main instrument panel will come on (see
page 56).
Use the Saab Information display (SID) to
check the approximate distance that can be
travelled on the remaining fuel
(see page 62).
Refueling; see page 138.

136 Starting and drivingUseful 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 revving faster than 6,200 rpm by
temporarily shutting of the fuel injec-
tors.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.

141 Starting and driving
Gear changingManual transmissionTo start the engine the clutch pedal must
be fully depressed.
The gear positions are marked on the gear
lever. Before reverse (R) can be engaged,
you must lift the ring underneath the
gear-lever knob.
To change gear, fully depress the clutch
pedal and then release it smoothly. It is
inadvisable to drive with your hand resting
on the gear lever, as this can increase the
wear on the gearbox.
When shifting down from 5th to 4th gear,
ease the gear lever straight back, without
applying any lateral pressure. This will pre-
vent 2nd gear being engaged by mistake,
which can result in overreving and possible
damage to the engine.
Shift-up indicator for improved fuel
economy
(U.S. models only)Cars equipped with a manual transmission
have a "Shift-up" light on the instrument
panel. The light begins to work after the
vehicle is warmed up and provides you with
a good indication when to shift to a higher
gear.
It is not necessary or recommended to
follow the shift-up recommendations in all
driving conditions, for example, when driv-
ing in heavy urban traffic or steep downhill
grades.
However, shifting with the light should result
in improved fuel economy. Therefore, for
reduced fuel consumption and better
energy conservation, you should make a
habit of shifting before or when the shift-up
light comes on.
Automatic transmission

NOTEWhen the reverse gear is to be engaged
the car must be at a standstill with the
accelerator fully released. Lift the reverse
lock-out collar and push the gear lever
firmly to the right in neutral before easing
it into reverse.
WARNING
 Make it a habit to keep your foot on the
brake when selecting a drive position,
to prevent the car from creeping for-
ward (or backwards if reverse is
selected).
 The car must be at a standstill before
P, R or N is selected. You have to have
your foot on the brake pedal to move
the lever out of park. If the car is still
moving when a drive position is subse-
quently selected, this could cause an
accident or damage the automatic
transmission.
 Never park the car with the selector
lever in a drive position, even if the
parking brake is on.
 If you want to leave the car with the
engine running, move the selector
lever to P or N and apply the parking
brake.

142 Starting and drivingThe electronic control module for the auto-
matic transmission receives information on
engine torque and road speed. It also con-
trols the hydraulic pressure in the transmis-
sion to ensure that gear changing is as
smooth as possible.
The position of the selector lever is shown
by the symbols adjacent to the lever and
also by an indicator on the main instrument
panel.
The ignition key can only be removed when
the selector lever is in the P position.When the car is stationary, the engine must
be idling when the selector lever is moved.
You must have your foot on the brake
pedal to move the lever out of park. If the
accelerator is depressed while the lever is
moved, this will result in abnormal wear in
the transmission. The detent button on the selector lever has
to be pressed before the selector can be
moved between certain positions.
Three modes for the automatic transmis-
sion can be selected: Normal, Sport and
Winter.
The Normal mode, which provides the best
fuel economy, is the default setting when
the engine is started.
Sport mode alters the angle of the throttle
valve for increased power compared to the
same accelerator position in Normal mode.
This means gear changes are made to opti-
mize the car’s performance. The SPORT
indicator light is shown on the main instru-
ment panel; see page 147).
The Winter mode is intended for use when
pulling away and driving on icy roads. In this
mode, the transmission starts in 3rd gear, to
NOTEAfter selecting a drive position, pause
briefly to allow the gear to engage (the car
starts to pull a little) before you acceler-
ate.

154 Starting and driving Driving in a low gear results in higher fuel
consumption than in a high gear because
of the lower engine speed for a given road
speed. Always change up to a higher gear
as soon as traffic conditions allow and use
the highest gear as much as possible.
 Check the air pressure in the tires once a
month. Incorrect pressures increase tire
wear. It is better to have slightly higher
pressure than lower.
 Check fuel consumption regularly.
Increased consumption can indicate that
something is wrong and that the car
needs to be checked by an authorized
Saab dealer.
Practical tests on the roads have demon-
strated that substantial savings in fuel con-
sumption can be made if the above advice
is heeded.Road conditions Wet 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 heater (standard
equipment in Canada, accessory in
U.S.)The 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 block heater is effective with
outside temperatures up to +60 – +70°F
(+15 – +20°C). The warmer it is outside, the
shorter the time the heater need be con-
nected. Longer than 1.5 hours is unneces-
sary.
If the car is equipped with a removable elec-
trical cabin heater that is not in use, this
should be stored in the luggage compart-
ment.
Driving in cold weatherBefore starting a journey in cold weather
you should check the following:
 That the wiper blades have not become
frozen to the windshield/glass.
 Brush any snow away from the air intake
for the heater system (opening between
hood and windshield).
 It may be advisable to lubricate the
door-lock cylinder (use molybdenum
disulphide, MoS
2) to prevent its freezing.
If the lock has frozen, take care not to
break the key (or use the remote control)
– heat it first or spray it with de-icer.
 Periodically during the winter, add gaso-
line anti-freeze to the fuel to dispel any
condensation in the fuel tank which could
freeze and cause problems in the system.
Keep the tank well filled to reduce the risk
of condensation forming.
If the car is parked outside in freezing
weather, fuel additives (gasoline
anti-freeze) will not do any good as it
cannot remove water that has already fro-
zen. Park the car in a warm place so that
any ice that may have built up melts, then
add gasoline anti-freeze when filling up
the tank. Condensation is caused by
changes in the outdoor temperature or by
the car being parked alternately in a
garage and outside.
 It is particularly important when the roads
are slippery that the brakes and tires be in
good condition.
