63 Instruments and controls
Central warning light
This light comes on and a chime will sound
if a fault has been detected in any system
that is critical to safety. Any of the following
can activate the central warning light and
alarm:
 Airbag system.
 Low oil pressure in engine.
 Parking brake is on (when car is moving).
 Brake fluid level low.
 Fault detected in ABS system.
 Electronic brake force distribution (distri-
bution of brake pressure between front
and rear wheels).
 Engine overheating.
 Alternator not charging properly.
Cruise Control
indicator light
The symbol is lit when cruise control is
active.
Engine malfunction
(CHECK ENGINE)
This light indicates a malfunction in the
fuel-injection or ignition system. The car
may still be driven with care and with some-
what diminished performance.
SPORT Mode Indicator
(automatic transmission)
On cars with automatic transmission the
indicator light comes on when you press the
SPORT button on the gear-lever knob.
In SPORT mode, the transmission remains
longer in the (D, 3, 2, 1) gears before
upshifting.
Cancel Sport mode by again depressing the
SPORT button; see also page 162.
WARNING
An illuminated CHECK ENGINE indicator
light indicates a serious engine-related
problem. While your car may be able to be
driven with the CHECK ENGINE indicator
light illuminated (limp-home mode), you
are advised to have your car serviced at
an authorized Saab dealer as soon as
possible.
Continued driving without this problem
being corrected might cause serious fur-
ther damage to your car and create
unsafe driving conditions. The operator
should be prepared to take action if such
unsafe conditions arise (e.g., apply the
brakes, disengage transmission, turn off
the ignition etc.).
NOTEThe car should be checked immediately
at an authorized Saab dealer to prevent
more serious faults from arising.

65 Instruments and controls
Traction Control System
indicator (option)
The lamp in the tachometer lights up
when the TCS system is activated, i.e. when
the friction between the tires and road
surface is insufficient for the car to acceler-
ate as desired. You may also experience
that the engine does not respond as normal
when the accelerator is depressed.
Operation of the TCS indicates reduced
cohesion between the tires and the road,
and that extra care should be taken by the
driver.
During normal driving, the TCS will help to
improve both ride comfort and safety, but
must not be regarded as a system to enable
the driver to maintain a higher speed. The
same precautions for safe cornering and
driving on slippery roads must still be
adopted (see page 166.
Traction Control System
OFF indicator (option)
This light comes on when the traction
control system (TCS) is switched off with the
TCS button.
IMPORTANT! The traction control system is
switched on automatically each time the car
is started (see page 166).
This indicator light also comes on if a fault
has been detected in the TCS, in which case
the lamp will not be extinguished when the
TCS is switched off by means of the TCS
button. If a fault is indicated, have the
system checked at an authorized Saab
workshop.
See also the section Traction Control Sys-
tem, on page 166.
Autochecking of lights,
main instrument panel The above warning and indicator lights
should come on when the ignition is
switched on. They go out after about 3 sec-
onds.
The following lamps light up until the engine
starts, as long as no faults exist:
Central warning light .
Oil pressure warning light .
Charge warning light .

179 Starting and driving
Driving with the trunk lid
openAvoid driving with the trunk lid partly or fully
open, since exhaust fumes can be drawn
into the cabin.
If you must drive with the trunk lid open, all
windows and the sunroof (if fitted) must be
closed and the cabin fan on at its highest
speed setting.Driving in deep waterTowing the car
The car is fitted with towing eyes at both
front and rear. For access to the front towing
eye, located on the right-hand side of the
car, compress the grille (see illustration)
and pull it straight out.
If the car is equipped with a trailer hitch, this
can be used to tow another car.
Transporting the car NOTE
Do not drive in water deeper than 11”
(30 cm) and do not drive faster than at
idling speed. Water can otherwise be
sucked into the engine. The engine will be
damaged if water enters the intake sys-
tem. The car´s electrical systems may
also be affected.
WARNING
 The towing vehicle should always be
heavier than the vehicle being towed.
 Never allow passengers to ride in the
car being towed.
 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 pump operate
when the engine is off. The steering
will therefore be much heavier than
usual.
 Always seek professional help if the
car needs to be towed. NOTEDo not confuse the front towing eye with
the oil pipe for the power steering.
NOTEIf a car with sports (lowered) chassis is
transported, for example on a flat bed
truck, take extra care not to damage the
spoiler and/or underbody.

184 Starting and drivingDriving considerations
with compact spare
wheel/tire fitted The following should be observed when the
compact spare wheel (T115/70 R16) is
installed:
The compact spare is light and easy to
handle when changing the wheel. Do not
drive farther than necessary with the com-
pact spare fitted – the maximum life of the
wheel is only just over 2000 miles
(3,500 km). Have the standard wheel
repaired and reinstalled as soon as possi-
ble.Points to bear in mind when driving with a
compact spare wheel:
 The car’s ground clearance is reduced
with the compact spare fitted.
 Only one compact spare wheel may be
used at any time.
 Take care not to hit the curb.
 Do not fit snow chains.
 Leave the wheel cover off, so that the
warning text is readily visible.
For long tripsBefore starting off on a long journey, it is
advisable to have your car inspected by
your Saab dealer.
Obtain a few important items to take along
on your journey such as spare bulbs, wiper
blades, fuses, a Poly-V belt and the like.
You can check some points yourself before-
hand:
 Make sure that the engine is in good con-
dition.
 Check that no oil or fuel leaks out of the
engine or gearbox/transmission.
 Check the coolant and power steering
fluid levels. Check also for leaks.
 Inspect the Poly-V belt and replace it if it
shows any signs of wear.
 Check the battery charge.
 Check the tires for tread pattern and air
pressure, including the compact spare
wheel.
 Take an extra car key/remote control and
keep it separate, see also page 36.
 Check the brakes.
 Check all bulbs.
 Check for the presence of the tool kit and
the jack in the car.
WARNING
Do not exceed 50 mph (80 km/h) as the
tire can overheat and adversely affect the
handling of the car.
The tire should be inflated to 60 psi
(420 kPa).
NOTETo avoid damaging a punctured alloy
wheel this can be placed outside up in the
spare-wheel well but only while driving to
the closest dealer.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 142.

238 Technical dataOil specification
Oil for gasoline engines is classified by the API (American Pe-
troleum Institute) and ACEA (European Automobile Manufac-
turers Associations) standards.
API classifies engine oil into grade classes SH (since 1993) and
SJ (since 1996). The SJ class fulfils more stringent require-
ments and has lower phosphorous level. A new grade API SL,
introduced 2001, fulfils even higher requirements.
These grade classes are most often combined with correspond-
ing classes for diesel engines. The class designations for diesel
engines begins with the letter "C" (Commercial). For example a
grade combination suitable for both types of engine could be
API SH/CD, SJ/CF or SL/CF.
Under the ACEA nomenclature, oils are divided into Class A for
gasoline engines and Class B for diesel engine passenger cars.
There is a further class for heavy diesel engines. Each class is
divided into grades: 1,2 and 3 where grades 2 and 3 normally
encompass semi- and fully synthetic oils. The diesel class also
has a fourth grade, B4, which encompasses tests and regula-
tions aimed at improving the performance of direct injection
diesel engines.
In the same way as in the API system, gasoline and diesel
engine specifications are combined for products that can be
used in both types of engine. For example, a grade designation
could be ACEA A2/B2 or ACEA A3/B3, B4.
Viscosity: The viscosity of oil is classified according to the SAE standard.
Nowadays, multigrade oils are always used in cars. The proper-
ties of these oils facilitate starting the car in cold weather but
mean that the oil is also viscous enough to coat all moving parts
under high pressures and with high outside air temperatures.
Multigrade oils are graded with two viscosity’s, e.g. 5W-30,
where 5W meets certain viscosity requirements at -4°F (-20°C),
while 30 fulfils requirements at 212°F (100°C).
