160 Starting and drivingThe detent button on the selector lever has
to be pressed before the selector can be
moved between certain positions. Four modes for the automatic transmission
can be selected: Normal, Manual, Sport and
Winter.
The Normal mode, which provides the best
fuel economy, is the default setting when
the engine is started.
Manual mode (Sentronic): see page 163.
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 166).
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 166).
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 temperature of the transmis-
sion. A suitable gear change pattern is then
selected automatically to avoid unneces-
sary gear changes and undesired tempera-
ture increases in the transmission.
Lock-up function The automatic transmission has a lock-up
function, which can render the torque con-
verter inoperative in 3rd, 4th and 5th gears,
thus reducing the engine speed and 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.
Following this, the next higher gear will be
selected at the optimum engine speed for
acceleration or, if you ease off the acceler-
ator, before reaching this.

174 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.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 above:
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
NOTICESuspension modifications, such as
changing the type of wheels, dampers or
springs, can affect the function of the ESP
system.
Always consult a Saab dealer before
changing any suspension components.

175 Starting and driving
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.
If 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).
WARNING
Never switch the engine off while driving
as the effect of the brakes and power
steering will be greatly reduced.

176 Starting and drivingEngine 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.
Exhaust emissions substantially reduced
over short runs.
Reduced wear on the engine.
Inside of car warms up faster.
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 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. Check the anti-freeze in the engine cool-
ant, see page 207.
The car´s trip computer will warn you when
there is a risk of slippery conditions. For fur-
ther information on this function, see page
64.
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.
Acquaint yourself with the legal provi-
sions governing the use of different
types of winter tires and snow chains.
Studded tires are not allowed in some
countries.

180 Starting and drivingWhen negotiating long hills, bear the follow-
ing important considerations in mind:
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.Recommendations for cars with
automatic transmission
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following steps are taken in order as the
temperature of the engine increases:
Gear change pattern is altered.
A/C compressor is switched off.
Engine torque is reduced.
The following message will be displayed on
the SID if the transmission fluid becomes
too hot: “Gearbox too hot. Make a safe stop.
If this message appears, stop the car as
soon as it is safe to do so and allow the
engine to idle until the message has gone
out. The selector lever should be in
position P.When continuing your journey, select
manual mode and a gear in which the
engine speed is about 3,000 rpm until the
incline eases (see page 164).
Do not drive continuously with the WINTER
mode selected in hilly country when you are
towing a caravan, as this will increase fuel
consumption and risk overheating the trans-
mission.
VARNING
Remember to use the braking effect of the
engine (position D or L) when you are
descending long or steep hills to spare
the brakes.
Brake failure can result from overheated
brakes!

184 Starting and driving4 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.
Fitting the roof carriers (accessory)
9-5 Wagon1 Clean the car’s roof rails.
2 Check the markings on the cross mem-
bers to see which is the front and which
is the rear roof carrier.
3 Place the cross members on the roof
rails, on their respective sides of the
center supports. The cross members
must not be placed beyond the front or
rear joint on the rail. Ensure that the dis-
tance between the cross members is at
least 28 inches (700 mm).
If a roof box is to be fitted, the cross
members must be positioned so that the
tailgate can be opened fully without hit-
ting the roof box.
4 Using your thumb, press the bracket so
that it lies snugly against the outside of
the roof rail. Make sure that the roof car-
riers are seated centrally on the rubber
spacers and that these sit correctly on
the roof rail. Pull the spacers down
slightly on the inside of the roof rail.
5 Center the roof carriers so that they pro-
trude equally on both sides.
6 Tighten the roof carriers by hand.
Ensure that the tightening knobs are
upright once the roof carriers have been
tightened.
7 Make sure the roof carriers are securely
in place.

186 Starting and drivingTires
The tire pressure should match the current
load and speed of the car; see page 279 or
the tire pressure label on page 280.
The tire pressures given apply to cold tires,
that is tires that are the same temperature
as the outside air temperature.
The tire pressure increases as the tires
become warm (e.g. during highway driving)
with approximately 0.3 bar (4 psi). When
the temperature of the tires changes by 50°
(10°C), the tire pressure will change 0.1 bar
(2 psi).Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Underinflated tires wear more quickly than
slightly overinflated tires.
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 drive at substantially lower or
higher speeds than normal.
WARNING
Check the tire pressure at least once a
month and before long journeys. Under-
inflation can result in:
Punctures
Separation of the tire and tread
Damage to the sidewalls
Damage to the rims on poor roads
Poor handling characteristics
Premature tire wear
Increased fuel consumption.
