Recommended fuel:For optimum performance we recommend:
 AON 90 for 2.0 Turbo 185 hp engines.
 AON 93 for 2.0 Turbo 205 hp engines and
2.3 Viggen.
Octane rating is determined according to
the formula:
where MON is the Motor Octane Number,
and RON is the Research Octane Number.
The average of these two values is the
octane rating of the gasoline as it appears
on the pump at a retail gas station. This
value is sometimes referred to as the
"Anti-Knock Index" (AKI) or the "Average
Octane Number" (AON).To avoid deposit formation on the fuel injec-
tors which can cause poor driveability, use
only quality gasolines that contain deter-
gents and corrosion inhibitors. Because
gasolines sold at retail gas stations vary in
their composition and quality, you should
switch to a different brand if you begin expe-
riencing driveability and/or hard starting
problems shortly after refueling your car. In
recent years, a variety of fuel additives and
alcohols or oxygenates have been blended
with gasoline. These types of gasolines may
be found in all parts of the United States and
Canada, but particularly in geographic
areas and cities that have high carbon mon-
oxide levels. Saab approves the use of such
"reformulated" gasolines in its products,
which help in reducing pollution from all
motor vehicles, provided that the following
blending percentages are met by such
fuels:
 Up to 10% ethanol by volume, with corro-
sion inhibitors.
 Up to 15% MTBE by volume (methyl ter-
tiary butyl ether).
 Up to 5% methanol by volume, with an
equal amount of a suitable co-solvent and
added corrosion inhibitors.
NOTE 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.

155 Starting and driving
Engine Break-in PeriodPistons, cylinder bores and bearings need
time to obtain uniform, wear-resistant sur-
faces.
If a new engine is driven too hard, this grad-
ual process of bedding-in will not be possi-
ble and the life of the engine will be short-
ened.
During the first 1,200 miles (2,000 km), do
not exceed 5,000 rpm.
In addition, refrain from driving the car at full
throttle, other than for brief instances,
during the first 1,800 miles (3,000 km).Wearing in new brake padsNew brake pads take time to bed in, about
90 miles (150 km) if the car is driven largely
under stop-and-go conditions or about
300 miles (500 km) of highway driving.
To extend the useful life of the pads, avoid
hard braking as much as possible.
Manual 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 except Viggen)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.
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.

Automatic transmission
fault indicator
If the symbol appears on the main instru-
ment panel, the system has detected a fault
in the automatic transmission or its control
module (see page 64).
This also means that the Limp-home mode
has been selected, to guard against further
damage being done to the transmission. In
this mode, the automatic transmission
starts in 4th gear, and gear changes (if nec-
essary) will have to be made manually.
It is not possible to select the SPORT or
WINTER mode when the Limp-home mode
is active.
You should have the automatic transmis-
sion checked as soon as possible by an
authorized Saab dealer.
The following gears will be engaged in the
respective selector positions when the auto-
matic transmission is in the Limp-home
mode:
Overheated transmission oilIf the transmission oil becomes overheated
while driving, the following message
appears on the SID: TRANSMISSION
OVERHEATING. In this event, stop the car
in a suitable place, switch off the engine,
open the hood and wait until the message
goes out. When driving subsequent to the
transmission oil overheating, select either
3rd gear or Drive, whichever will allow the
engine to run at 3,000 rpm and maintain the
speed of traffic or a safe speed.
The transmission oil can become very hot
when the car is driven with a heavy load; for
example, driving with a trailer on hilly roads
when the wrong gear has been selected,
resulting in many extra gear changes.
Select one of the positions 1, 2 or 3. A high
outside temperature or a defective oil cooler
can also cause the oil temperature to
increase. Contact an authorized Saab
dealer, see also page 173.
Driving in hilly country with a heavy
loadOverheating of the automatic-transmission
fluid can occur when the car is towing a
heavy load, such as a trailer in hilly country,
with the wrong gear selected, resulting in
abnormally frequent gear changing. To
avoid the transmission oil from overheating
always drive in Normal mode, then the
adaptive gear change pattern is active.
High ambient temperatures can also
increase the temperature of the transmis-
sion fluid or the oil cooler may be faulty. As
the transmission fluid temperature
increases, its useful service life is reduced.
Contact an authorized Saab dealer (see
also page 173).TowingTowing a car with automatic transmission,
see page 181. Position R D 3 2 1
Gear Reverse 4th 4th 3rd 3rd
NOTEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 4th
gear when D and 3 are selected, making
it very sluggish. To overcome this, move
the selector lever to position 1. The trans-
mission then starts in 3rd gear. When the
car is moving you can select position D
or 3.
WARNING
Remember to use engine-braking (selec-
tor position 1, 2, or 3) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!

160 Starting and drivingSelector positions
P
To shift out of the P position you must depress
the brake pedal and the ignition must be OFF.
The parking position (P) must only be selected
when the car is at a complete standstill. The selec-
tor lever is locked and the transmission is
mechanically immobilized. Always apply the park-
ing brake after parking the car.
The engine can be started.
R
The reverse (R) position must only be selected
when the car is at a complete standstill. The
detent-release button must be pressed before the
selector lever can be moved to R. Wait until
reverse gear has engaged (car starts to creep)
before touching the accelerator.
N
In the Neutral position (N), the transmission is dis-
engaged from the engine. The engine can be
started, but first ensure that the parking brake is
on, to prevent the car from moving off unexpect-
edly.
To prevent the engine and transmission from
becoming hotter than necessary, select N for
stops other than brief ones, e.g. if stuck in a traffic
jam.
The normal drive position (D) is recommended for
waiting at traffic lights.
D
The Drive position (D) is the position for normal
motoring. Gear changes between 1st and 4th will
take place automatically, the timing of which is
determined by the throttle (accelerator) position
and the speed of the car.
After moving the selector lever to D, pause to give
the gear time to engage (car starts to pull).
3
In position 3, 4th gear is locked out. The car will
start in 1st gear and normal gear changing (up
and down) will take place automatically between
gears 1, 2 and 3.
Moving the selector lever from D to 3 will cause a
downshift to 3rd gear, which will give better
engine-braking.
Do not move the selector to position 3 at speeds
in excess of 90 mph (150 km/h).
2
Position 2 is recommended in hilly country as it
provides effective engine-braking. Normal gear
changing (up and down) between 1st and 2nd
gear will take place automatically. Third and 4th
gears are locked out.
Do not move the selector to position 2 at speeds
in excess of 70 mph (110 km/h).
1
Position 1 should be used when maximum
engine-braking is required on steep downhill
slopes.
Do not move the selector to position 1 at speeds
in excess of 30 mph (50 km/h).

165 Starting and driving
ABS brakes ABS (Antilock Braking System) modulates
the brake pressure to the respective
wheels. Wheel sensors detect if a wheel is
about to lock, and the control module
reduces the pressure to that wheel and then
increases it once more until the tendency is
detected again.
The brake system is equipped with an Elec-
tronic Brake-force Distribution device
(EBD), which distributes the brake pressure
between the front and rear wheels in such a
way as to achieve optimum braking per-
formance irrespective of the car’s speed
and load.
The ABS system has a built-in diagnostic
function which will switch on the ABS warn-
ing light if a fault is detected in the system
(see page 62). The ABS system will not reduce the braking
distance on loose gravel or on snow or ice
but, because the wheels cannot lock up,
some steering control is retained.
When the ABS system is working, i.e. mod-
ulation of the brake pressure is in progress,
the brake pedal will pulsate and a ticking
noise will be heard. All this is perfectly nor-
mal.
Press the pedal down hard (you cannot
press too hard) and steer the car to safety. Do not release the brake pedal before the
car has come to a halt or the danger is
past!
This is critical.
If the road is slippery, the ABS system will
operate even when only light pressure is
applied to the pedal. This means that you
can brake gently to test the condition of the
road and adapt your driving accordingly.
It is well worth practising the use of ABS
brakes on a skid pad or other suitable facil-
ity.
WARNING
 The additional safety afforded by the
ABS system is not designed to allow
drivers to drive faster but to make
normal driving safer.
 To stop as quickly as possible, without
loss of directional stability, whether
the road surface is dry, wet or slippery,
press the brake pedal down hard
without letting up (do not pump the
pedal), declutching simulta-
neously, and steer the car to safety.

Recommendations for driving in
hilly terrainThe following time limits are based on the
capacity of the cooling system in warm
weather, i.e. approximately 86°F (30°C).
The following time limits are based on the
capacity of the cooling system in hot
weather, i.e. approximately 104°F (40°C).It is important to consider the following when
driving a car with automatic transmission up
long inclines.
Use Normal mode when driving with a cara-
van or trailer on hilly roads. The adaptive
gear change pattern function will prevent
the transmission overheating.
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following may also occur:
 A/C compressor is switched off
 Gear change pattern is altered
 The CHECK message TRANSMISSION
OVERHEATING appears on the SID
If TRANSMISSION OVERHEATING
appears on the SID, stop the car as soon as
it is safe to do so and wait until the message
has been extinguished. When driving sub-
sequent to the transmission oil overheating,
select either 3rd gear or Drive, whichever
will allow the engine to run at 3,000 rpm and
maintain the speed of traffic or a safe speed;
see page 159.Do not drive continuously with the WINTER
mode selected in hilly country when you are
towing a trailer, as this will increase fuel con-
sumption and risk overheating the transmis-
sion.
Driving considerationsAlways take extra care when towing a
trailer, as the car’s handling will be different
and its braking effect reduced. The trailer’s
braking system and suspension also have a
considerable effect on these characteris-
tics, see also "Driving with a load" page
178.

197 Car care
Drive beltThe alternator is situated on the right-hand
side of the engine. It is driven via a poly-V
belt from the crankshaft pulley.
The poly-V-belt also drives the water pump,
the A/C compressor and the steering servo
pump.
The belt tension is critical, and is adjusted
by an automatic belt tensioner.
See also page 61, "Warning charging".
WARNING
 Keep hands and clothing clear of drive
belts when engine is running.
 Always stop the engine before
inspecting drive belts.
 The fan can start even when the
engine is switched off.NOTESerious damage can occur to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.
