137 Starting and driving
Engine Break-In PeriodPistons, bores and bearings need time to
obtain uniform, wear-resistant surfaces.
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 during
this period.Brake-pad wear indicatorsThe outer brake pads on the front wheels
have acoustic wear-indicators. When 3 mm
remains on the pad, a scraping or screech-
ing noise is heard during braking. The brake
pads should be changed as soon as possi-
ble.
Brake pads should only be replaced by
an authorized Saab dealer.
Gear changingManual gearboxTo 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 changing 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.
Before engaging reverse, wait till the car is
at a standstill, release the accelerator and
fully depress the clutch. From neutral, press
the gear lever firmly to the right before
easing it back into reverse.
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.Towing Towing of cars with manual gearbox, see
page 158.

139 Starting and driving
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.
When the Sport mode is selected, the
throttle angle is altered to provide more
power at the same throttle setting. The
transmission also changes up later than in
Normal mode to provide higher perfor-
mance. In this mode, the SPORT indicator
will appear on the main instrument panel
(see page 144).
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
provide better grip, and the WINTER indica-
tor appears on the main instrument panel.
When the ignition is turned to OFF, the auto-
matic transmission will automatically revert
to Normal mode (see page 144).
Adaptive gear-change pattern is a trans-
mission function in the Normal and Sport
modes which matches gear changing to
current driving conditions. The transmission
control module senses the load on the
engine and selects one of three available
gear-change patterns, and so avoids
unnecessary changing up or down.
Lock-up function The automatic transmission has a lock-up
function, which renders the torque con-
verter inoperative in 3rd and 4th gears, the
result of which is to reduce the engine speed
and, hence, fuel consumption.
When the lock-up function comes into oper-
ation, it may give the impression of an over-
drive being engaged.Kick-downWhen the accelerator is pressed down hard,
a change-down to the next gear will be
effected to provide maximum acceleration,
e.g. for overtaking.
The change-up to the next gear again will
take place either when the accelerator is
released or when maximum engine speed is
reached.

149 Starting and driving
Economical motoringFactors affecting fuel consumption Fuel consumption is greatly affected by the
general driving conditions, the way in which
the car is driven and at what speeds, the
weather, the state of the road, the condition
of the car, etc. Breaking-in Fuel consumption may be somewhat higher
during the break-in period (the first 3,000–
4,000 miles (5,000–7,000 km) than stated
under ”Technical data”.
Weather conditions Fuel consumption can be as much as 10 %
lower in summer than in winter. The higher
consumption in cold weather is explained by
the longer time it takes for the engine to
reach normal operating temperature, and
for the transmission and wheel bearings to
warm up. Fuel economy is also affected by
the distance driven: short journeys of
3-5 miles (5-8 km) do not give the engine
enough time to reach normal temperature.
Strong winds can also affect fuel consump-
tion.
How to read the graph on the right:
If fuel consumption with the engine at
normal temperature is 28 mpg
(10l/100 km), the actual fuel consumption 3
miles (5 km) after the engine has started
from cold will be:
– 23.5 mpg (12l/100 km) at outside temp.
of 68°F (20°C) (increase of 20%).
– 17.7 mpg (16l/100 km) at outside temp.
of 32°F (0°C) (increase of 60%).
– 14 mpg (20l/100 km)) at outside temp. of
–4°F (–20°C) (increase of 100%).
As can be seen, both the distance travelled
by the car and the outside temperature have
a major impact on fuel consumption after
the engine has started from cold. Thus, if the
car is mainly used for short journeys of
3–5 miles (5–8 km), the fuel consumption
will be 60–80 % higher than normal.
Driving technique To obtain the best running economy, not
only regarding fuel consumption but gen-
eral wear also, regular service is required.
 High speed, unnecessary acceleration,
heavy braking and much low gear work all
gives rise to higher fuel consumption.
 Frequent gear changing in traffic, starting
in cold weather, the use of studded tires
and roof racks, and towing a trailer all
increase fuel consumption.
 Do not run the engine when the car is sta-
tionary.

150 Starting and drivingIf idling, it will take much longer before the
engine becomes hot. Engine wear is
greatest during this warming-up phase.
Therefore drive away as soon as possible
after the engine is started and avoid high
revving.
 Driving in a low gear results in higher fuel
consumption than in a high gear because
of the higher 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 pos-
sible.
 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 trials 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 heater is effective at outside
temperatures up to +15-20°C. The warmer
it is outside, the shorter the time the engine
heater needs to be connected. Longer than
1.5 hours is unnecessary.
If the car is equipped with a removable,
electrical cabin heater that is not in use, this
should be stored in the luggage compart-
ment.
Driving in winterBefore starting a journey in cold weather,
check that the wiper blades have not
become frozen to the glass. Brush any snow
away from the air intake for the heater
system (opening between hood and wind-
shield).
Periodically during the winter, add gasoline
anti-freeze to the fuel to dispel any conden-
sation in the fuel tank which could freeze
and cause problems in the system. Keep
the tank well filled to reduce the risk of con-
densation forming.
If the car is parked outside in freezing
weather, fuel additives (gasoline
anti-freeze) will not do any good as any con-
densation in the fuel tank will freeze. Con-
densation is caused by changes in the out-
door 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.
The car is equipped with tires designed to
provide optimum grip on both wet and dry
roads, although this has been achieved at
the expense of somewhat reduced grip on
snow and ice. For regular driving on snow
and ice, we therefore recommend that
winter (snow) tires be fitted.
Winter (snow) tires, particularly studded
tires (where use is legally permitted), gener-
ally make driving safer on snow and ice.
If winter tires are fitted, the same type must
be fitted on all wheels. Your Saab dealer will

155 Starting and driving
Driving with a roof rack
loadThe maximum permissible roof load is
220 lbs. (100 kg).
Note that the roof load is included in the
car’s maximum permissible load (see page
226).
Strong, sturdy roof carriers designed spe-
cially for the car are available from your
Saab dealer. Always secure the roof load
safely. Fitting the roof carriers (accessory)
9-5 SedanThe carrier feet are marked with a top view
of the car and arrow indicating their posi-
tions.
1 Slip the plastic cover onto the adjustable
foot of the carrier (foot with knob for
tightening) to protect the paintwork
during assembly.
2 Open all the doors.
Fold back the rubber strip and find the
fixing holes. 3 Start on the left-hand side of the car.
Rest the carrier carefully across the roof,
with the rigid foot towards you. Hold the
foot clear of the roof to avoid damaging
the paintwork.
Fold back the rubber strip and insert the
pins on the foot into the fixing holes.
Make sure that the rubber strip comes
inside the plastic cover on the carrier.
Repeat the procedure with the other car-
rier.
4 Close the doors on the left-hand side of
the car gently, to hold the carrier feet in
place.
5 Now go around to the other side of the
car and remove the plastic cover from
the carrier’s adjustable foot. Fold back
the rubber strip and insert the pins on
the foot into the fixing holes. Do the
same with the other carrier and close the
doors gently. 6 Tighten each carrier by turning the knob
clockwise (by hand). Tighten just
enough to bring the foot up against the
edges of the fixing holes.
Remove the carriers when not in use, as
they increase fuel consumption.
The instructions that accompany the carri-
ers also include advice on driving with a roof
load - we strongly recommend that you read
them carefully.
WARNING
 A roof load will affect the car’s center
of gravity and aerodynamics. Be
aware of this when cornering and driv-
ing in crosswinds.
 Suit your speed to the prevailing con-
ditions.

169 Car care and technical information
Engine familiesSaab cars imported into the United States
and Canada meet all applicable emission
control standards. The engine family and
appropriate tune-up specifications are iden-
tified on a label affixed to the left front inner
fender.
These engine families meet applicable EPA
Federal Standards, California State Stan-
dards and Canadian Federal Standards and
are equipped with the following systems:
• Sequential multiport fuel injection system.
 Three way catalytic converter.
 Crankcase emissions control system.
 Evaporative emission control system.
 On-Board diagnostic (OBD II) system.
Emission control
systemsThe systems for controlling emissions to the
atmosphere require regular checking and
adjustment at the intervals specified in the
service program.
In addition to meeting the exhaust emission
regulations and thereby helping to keep the
environment clean, a correctly tuned engine
will also give maximum fuel economy.Saab Trionic engine management
systemThe Saab Trionic engine management
system is a unique Saab development that
combines sequential multiport fuel injection,
electronic distributorless ignition and turbo-
charger boost pressure control into one sys-
tem.
The Trionic engine control module (ECM)
monitors many different engine parameters
such as:
 Intake manifold pressure.
 Intake air temperature.
 Crankshaft position.
 Engine coolant temperature.
 Throttle position and
 The oxygen content of the exhaust gases.
The ECM receives information regarding
engine knocking from a sophisticated feed-
back function in the ignition discharge unit.
By processing all of this information, the Tri-
onic system can control fuel injector open-ing duration, ignition timing and turbo-
charger boost pressure to provide excellent
engine performance while maintaining low
emissions and fuel consumption.
NOTEThe Trionic engine management systems
continuously monitors the operation of
these systems and have on-board diag-
nostic capabilities (OBD II).
If the “Engine malfunction” lamp in
the main instrument illuminates, this indi-
cates that the Trionic ECM has detected
a problem. The car will continue to oper-
ate, but performance may be diminished.
You should have your car checked by a
Saab dealer as soon as possible.

198 Car care and technical informationWheels Alternative wheels and tiresIf you wish to fit other tires or wheels than
those supplied with the car, consult your
Saab dealer first as to the possibilities avail-
able.
Wheels/tires combinations that are not
approved by Saab can negatively affect the
car´s directional stability, steering and brak-
ing in both wet and dry conditions.
Do not assume that a wheel/tire combina-
tion will function properly just because it will
bolt on.The wheels and tires have been carefully
matched to the characteristics of the car and
play a key role in its outstanding roadhold-
ing and handling.
Tire pressureTires need to be inflated to suit the load car-
ried and the maximum speed the car will be
driven (see the recommended tire pres-
sures on the back cover). Note that all
values apply to cold tires. For tires with an
aspect ratio less than /60, increase the tire
pressure by 3 psi (20 kPa) for rough roads
with potholes to minimize the risk of rim
damage.Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Soft tires will cause faster wear than
over-pressurized tires. They also increase
fuel consumption.
If a valve is leaking, simply unscrew it and fit
a new one.
Important! Remember to adjust the tire
pressures if you change the load in the car
or intend to cruise at a substantially higher
or lower speed than normal.
NOTEFor wide wheels and/or low-profile tires,
bear in mind the following:
 Tires and wheels can be damaged in
potholes etc.
 Springs and dampers can be over-
loaded.
 The wheels can come into contact with
chassis and body components.
 The speed and load limits for the tires
must not be exceeded; see page 199.
 Wheels larger than 17” must not be fit-
ted. The maximum permissible offset
is 49 mm.
NOTECheck the tire pressures at least once
per month.
Underinflation is the main cause of:
 Tires wearing out prematurely.
 Damage to the sidewalls.
 Damage to the wheels.
