163 Starting and driving
Descending hillsIf the speed of the car increases while
descending a steep hill, despite the acceler-
ator being released, the control module will
change down a gear when you brake. If you
desire more powerful engine braking, man-
ually select a lower gear.
Sentronic, manual modeMove the selector lever to the M position.
Select a higher gear by flicking the
right-hand paddle towards you. Select
a lower gear by flicking the left-hand paddle
towards you.
An example of when you may wish to make
manual gear changes is when overtaking, to
enable you to remain in a low gear for an
extended period of time.
Changes from 3rd to 4th and from 4th to 5th
can be made when the engine speed is
above roughly 2,000 rpm.
If you select a gear that is judged too high by
the system, the selected gear position will
be shown briefly on the main instrument
panel and then the gear that is actually
engaged.
If the road surface is slippery, you may wish
to pull off in 2nd or 3rd to reduce the risk of
wheel spin.
When descending hills you should select a
low gear to increase the braking effect of the
engine and thus spare the brakes.
Manual gear selections are shown on the
main instrument panel. The selector posi-
tion and the current gear are displayed.When the selector lever is in the M position,
as opposed to the D position, gas engines
are much more responsive to changes in
accelerator position. The accelerator has a
different feel.
When in manual mode, kick-down operates
for 4th and 5th gears (below 2,000 rpm).
Kick-down cannot be activated in 1st, 2nd or
3rd gears.
For optimum performance, gear changes
should be made before reaching 6,000 rpm.
To avoid damaging the engine and trans-
mission, the transmission will shift up a gear
if the engine is in danger of overrevving. You
may feel a slight jolt before this gear change
is effected.

170 Starting and drivingThe ABS system has a built-in diagnostic
function which will switch on the Anti-lock
brake warning light if a fault is detected in
the system (see page 56).
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!
That 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 practicing the use of ABS
brakes on a skid pad or other suitable facil-
ity.

172 Starting and drivingTCS OFF The indicator on the main instrument
panel will come on:
 If a fault has been detected and the
system has therefore been switched off.
 If there is a fault in the ABS system.
 If the system has been switched off man-
ually.
The indicator light will also come on for
4 seconds when the ignition key is turned to
ON, while an internal system check is per-
formed.
Turning 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 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.
Electronic Stability
Program (ESP)The Electronic Stability Program employs
both the antilock braking system (ABS) and
the traction control system (TCS). It is a
safety system that helps the driver to stabi-
lize the car in unusual circumstances that
can otherwise be difficult to handle.How the ESP system worksThe Electronic Stability Program can help to
prevent the car from skidding by braking
one or several wheels independently of the
driver. The engine output is then also
reduced to prevent the driving wheels from
spinning. The car has sensors that measure
wheel speed, yaw acceleration, lateral
acceleration, steering wheel position and
braking pressure. The values provided by
these sensors are used to calculate the
actual direction of the car. If this direction
does not agree with that intended by the
driver, calculated from the steering wheel
position, the ESP is engaged.

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.

185 Starting and driving
Driving at nightBear in mind the following points when
driving at night:
 Nighttime driving requires your full con-
centration.
 Do not rush. Count on your journey taking
slightly longer.
 The number of drivers under the influence
of drugs is likely to be greater at night than
during the day.
 Do not stare at the headlights of oncom-
ing vehicles.
 Avoid driving at night if you have poor eye-
sight. Night vision deteriorates with age.
 Keep your car's headlights, windows and
mirrors clean. Also, if you wear glasses,
make sure they are clean.
 Make sure you are well rested before
starting a long journey. Take a break every
other hour.
 Only eat light meals. Heavy meals have a
tendency to induce tiredness.
Driving with a loadThe driving characteristics of the car are
affected by the way it is loaded.
 Place heavy loads as far forward and as
low as possible in the trunk.
 Secure the load to the tie downs, see
page 137.
 The load should be such that the car´s
total weight or axle weight are not
exceeded, see page 270.
 Heavy loads mean that the car’s center of
gravity is further back. As a result, the car
will sway more during evasive steering.
 Never exceed the permissible load in the
roof box, even if there is room for more.
 Ensure that the tire pressure is correct –
slight overinflation is preferable to under-
inflation.
 The braking distance of a loaded car is
always greater. Keep your distance from
the vehicle in front.
 Roof loads can negatively affect tele-
communication.
Tire pressure, see page 280 and back
cover.

188 Starting and drivingDriving with the trunk
lid/tailgate openAvoid driving with the trunk lid/tailgate partly
or fully open, since exhaust fumes can be
drawn into the cabin.
If you must drive with the trunk lid/tailgate
open, all windows and the sunroof (if fitted)
must be closed and the cabin fan on at its
highest speed setting.
Driving in deep water Towing the carNOTICEDo not drive in water deeper than
12 inches (30 cm) and do not drive faster
than 3–4 mph. Water can otherwise be
sucked into the engine. The engine will be
seriously damaged if water enters the
intake system.
WARNING
 Remember that the brake servo does
not operate when the engine is off.
Much greater pressure than normal
will therefore be required to operate
the brake pedal.
 Nor does the steering servo operate
when the engine is off. The steering
will therefore be much heavier than
usual.
 The towing vehicle should always be
heavier than the vehicle on tow.
 Never allow passengers to ride in the
car being towed.
 Always seek professional help if the
car needs to be towed.
