158 Starting and drivingGear 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 transmission.
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 transmission,

160 Starting and drivingThe 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 165).
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 165).
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.

170 Starting and drivingTurning the TCS off The TCS is switched on automatically when
the engine is started.
The system can be switched off manually by
the TCS button, whereupon TCS OFF on
the main instrument panel will come on. The
TCS system cannot be switched off if the car
is travelling faster than 35 mph (60 km/h).
It may be necessary to switch off the system
if the car has become bogged down, for
instance. Press TCS to switch it on again.
If a fault is detected in the ABS system, the
TCS will be switched off automatically.
The cruise-control system will automatically
be disengaged after one second if it is active
when the TCS starts to operate.
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

171 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).
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.

172 Starting and drivingDriving 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 196.
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
58.
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.If winter tires are fitted, the same type must
be fitted on all wheels. Your Saab dealer will
be pleased to advise you on the best tires for
your car.
Remember that tires age. It may therefore
be necessary to change them before they
reach the legal wear limit, as they gradually
lose their friction properties.
The best response if the car gets into a
front-wheel skid is to freewheel (manual
gearbox only), i.e. disengage the clutch (so
that the wheels are neither driven or
retarded by the engine.
If the car has automatic transmission, ease
up on the accelerator and steer carefully in
the desired direction.
In a rear-wheel skid, steer in the same direc-
tion that the rear of the car is moving.

175 Starting and driving
Recommendations for cars with auto-
matic transmission.
The 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).
Use Normal mode when driving with a trailer
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 can also occur:
 the A/C-compressor can be shut off
 the gear-change pattern is changed
 the CHECK message TRANSMISSION
OVERHEATING can appear 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 warning
has been extinguished. When continuing
your journey, select a locked gear (1, 2 or 3)
that will allow you to drive at an engine
speed of about 3,000 rpm (see page 163). 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 considerations Always 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 179.
If the car is equipped with automatic trans-
mission, select position 1 when ascending
or descending steep hills. Gradient

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!
NOTEIf the ”Automatic transmission, fault indi-
cator” indicator comes on, cease
towing until the problem has been recti-
fied.

176 Starting and drivingTrailer hitch loadThe weight distribution on the trailer makes
a lot of difference to the handling properties
of the car and trailer combination. As
regards single-axle trailers, whenever pos-
sible, concentrate the load over the wheels
and keep it as low as possible.
The trailer should be loaded so that the
maximum load on the towbar ball is 5% to
7% of the trailer weight with a maximum per-
missible tongue weight of 165 lbs. (75 kg).
Note that this load must be added to the total
load for the car. If this now exceeds the
specified load capacity, the load in the lug-
gage compartment will have to be reduced
by a corresponding amount.
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
250).
Strong, sturdy roof carriers designed spe-
cially for the car are available from your
Saab dealer. Always secure the roof load
safely.
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.
 Due to higher aerodynamic drag, fuel
economy may suffer when driving with
a roof rack.

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.
