Electronic Stability
Program (ESP
®)
The system employs both the antilock brak-
ing system (ABS) and the traction control
system (TCS). It is a system that helps the
driver to stabilize the car in unusual circum-
stances that would otherwise be more diffi-
cult to handle.
How the ESP
® system works
The system 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.
The ESP
® system improves the driver’s
chances of retaining control over the car in
critical situations.
To ensure that the system works as
designed, the dimensions of all four tires
must be the same.
WARNING
When driving normally, the ESP
® system
will help to improve the stability of the car.
This does not mean that car can be driven
faster. The same care and prudence as
normally applied should be displayed on
cornering and when driving on slippery
roads.

The system applies the brakes to the
wheels as shown in order to reduce the
likelihood of the car skidding

169 Starting and driving
When an object is approximately 3 feet
(90 cm) from the car, the sound pulses
change character markedly. A distance of
about 3 feet (90 cm) is suitable if you wish
to load or unload the luggage compartment.
If the distance between an object and the
corner sensors does not change for three
seconds, e.g. if you are reversing alongside
a wall, the system will switch to monitoring
straight back. The system indicates if the
distance to the wall decreases again.
The system can be disengaged for when
driving with a trailer. Press and hold the CLR
button on the steering wheel when the dis-
play shows "PARK ASSIST", until the dis-
play shows "PARK ASSIST OFF". The
system is re-engaged in the same way. The
system is also always activated when the
ignition key is turned to ON. Pressing a steering wheel button briefly will
not disengage the system, the display will
simply show the previously selected func-
tion.
Ice, snow and dirt can affect the sensitivity
of the sensors. In such cases a continuous
tone will sound warning the driver that the
system cannot measure the distance to an
object. You can turn the system off by press-
ing and holding the CLR button for
1.5 seconds.
If the text "PARK ASSIST FAILURE" is dis-
played on the SID, have the system
checked by a workshop. We recommend
that you contact an authorized Saab dealer.NOTEReverse slowly so that you have time to
stop the car when the continuous tone is
heard at approx. 12 in. (30 cm).
NOTETo function well, the sensors must be kept
clean. Ice snow and dirt can affect their
sensitivity.
Do not spray the sensors or closer than
8 in. (20 cm) to the sensors with a pres-
sure washer, as this could damage them.

171 Starting and driving
Driving techniqueTo obtain the best running economy, not
only regarding fuel consumption but
general 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
stationary.
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
possible.
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 a workshop. We
recommend that you contact an autho-
rized 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 conditionsWet 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.

181 Starting and driving
Driving at nightBear in mind the following points when
driving at night:
Nighttime driving requires your full
concentration.
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
eyesight. 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 131.
The load should be such that the car´s
total weight or axle weight are not
exceeded, see page 260.
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 box3, 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 269.
Additional information on tires, see page
222.

183 Starting and driving
Driving with a spare
wheel fittedSee page 238.Driving 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 moonroof3 must
be closed and the cabin fan on at its highest
speed setting.
Driving in deep water Towing the carNOTEDo 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.

198 Car care and technical informationPower steering fluidCheck the level of the power steering fluid in
the reservoir regularly, in accordance with
the service program.
The wheels should point forward during the
check.
Clean around the cap before it is
unscrewed. Clean the dipstick. Screw in the
cap completely again before checking the
level.
The oil should lie between the MAX and MIN
marks when the oil temperature is about
70°F (+20°C). If the oil is colder the level can
be lower, and in higher temperatures the
level can be higher, both of which are
acceptable.
Top up with ”Power Steering Fluid CHF 11S
or CHF 202”.
Air filter
WARNING
Do not fill the power steering fluid to
above the MAX mark. Too much fluid
can result in leakage.
Power steering fluid on hot engine
components constitutes a fire risk.
WARNING
For Service and Repair, parts equiva-
lent to those used by Saab should be
used.
Be aware that some non standard
replacement parts may put you in an
unsafe condition, even if they might fit.
