152 Starting and driving
AON 93. One of the advantages of the
system is that it enables the engine to
be run safely on lower-grade fuel,
although not lower than AON 87.
The maximum boost pressure is
adjusted automatically to the knocking
or pinging tendency of the engine.
Occasional, short-lived knocking when
the engine is under a heavy load is per-
fectly normal; the extent will depend on
the grade of fuel in the tank.
Isolated instances of knocking are
more likely to occur with low-octane
fuel. This controlled form of knocking,
followed by a reduction in the boost
pressure, is a sign that the wastegate is
functioning and is perfectly safe for the
engine.
Important considerations with cata-
lytic convertersThe catalytic converter is an emission-con-
trol device incorporated in the car’s exhaust
system. It consists of a metal canister with a
honeycomb insert, the cells of which have
walls coated in a catalytic layer (mixture of
precious metals).
To ensure that the catalytic converter con-
tinues to function properly, and also to avoid
damage to the converter and its associated
components, the following points must be
observed:
Have the car serviced regularly in accor-
dance with the service program. The fuel
and ignition systems are particularly
important in this context.
Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to an authorized Saab
dealer as soon as possible.
If the engine fails to start (in very cold
weather or if the battery is flat), the car can
be jump started (manual gearbox only) or
started using jump leads to a donor bat-
NOTEIf constant knocking occurs every time a
load is put on the engine, this indicates a
malfunction in the system.
Have the car checked without delay by an
authorized Saab dealer.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, to ensure
adequate cooling, air must be blown into
the engine compartment and under the
car at a rate equivalent to the ram-air
effect that would be obtained at the corre-
sponding road speed.
NOTEUse only unleaded gasoline. Leaded gas-
oline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

162 Starting and driving
Overheated transmission fluid If the automatic-transmission fluid should
overheat, the following message will appear
on the SID:
”TRANSMISSION OVERHEATING”. If this
happens, stop the car and wait for the mes-
sage to be extinguished. Continue driving in
a locked gear that produces an engine
speed of about 3,000 rpm.
Overheating of the automatic-transmission
fluid can occur when the car is towing a
heavy load, such as a camping trailer in hilly
country, with the wrong gear selected,
resulting in abnormally frequent gear
changing. Try selecting position 1, 2 or 3.
High ambient temperatures can also
increase the temperature of the transmis-
sion fluid or the oil cooler may be faulty.
Contact an authorized Saab dealer (see
also page 174).
Driving on hilly roads with a heavy
loadThe transmission fluid can overheat when
the gearbox is strained, for example, when
driving with a trailer on hilly roads with the
wrong gear is selected, resulting in many
extra gear changes. To avoid the transmis-
sion fluid overheating, always drive in
Normal mode. The adaptive gear change
patterns are then active.
High air temperatures or a faulty oil cooler
can also cause the transmission fluid to
overheat. Overheating reduces the service
life of the fluid. Contact an authorized Saab
dealer (see also page 174. Towing Towing of cars with automatic transmission,
see page 181.
NOTEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 4th
gear when D is selected, making it very
sluggish. To overcome this, move the
selector lever to position 2.
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!

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.

182 Starting and drivingRear towing eyeThe car has a permanently mounted towing
eye at the back. If the car is equipped with a
trailer hitch, this can be used instead of the
towing eye. Considerations when towing the car
with manual transmission Gear lever in neutral and parking lights on.
Drive carefully and do not exceed the
speed limit for vehicles being towed.
Always try to keep the towrope taut by
gently applying the brake, as necessary.
This will avoid the towrope being jerked
violently.
Considerations when towing the car
with automatic transmission Selector lever at N (neutral) and parking
lights on.
Drive carefully and do not exceed the
speed limit for vehicles being towed.
Always try to keep the towrope taut by
gently applying the brake, as necessary.
This will avoid the towrope being jerked
violently. 1 Selector lever in position N.
2 Raise the oil level in the gearbox above
normal by 2 extra quarts. Use oil of type
Texaco Texamatic Dexron III.
3 The local regulations on towing speeds
must be followed.
The highest permissible towing speed is
30 mph (50 km/h), unless the legal limit
is lower. The longest permissible towing
distance is 25-30 miles (40-50 km). If the
car has to be transported farther than
that, summon a tow truck. A flat bed tow
truck is the preferred method to tow.
4 When the car is being returned to ser-
vice, check the gearbox oil, and reduce
it to the prescribed amount if necessary.
Failure to follow these guidelines can result
in damage.
Cars with automatic transmission cannot be
bump started. In an emergency, it is possi-
ble to start the engine using jump leads (see
the section, ”Jump starting” on page 183). NOTE The car must be towed front first.
If the car is to be towed with the front
wheels off the ground, make sure the
parking brake is off, as this acts on the
rear wheels.

236 Car care and technical information4Inspect the undercoating and touch
up if necessary. Pay particular atten-
tion to the fenders and wheel housings,
which are exposed to abrasion by flying
gravel, etc. If the composition has worn
or flaked off, the steel must be thor-
oughly cleaned and dried before a fresh
coat is applied. The cleaning is best
done with a scraper and a steel wire
brush, followed by washing with solvent.
Apply the new coating thinly, as other-
wise it may run off or fall off when dry.
For long tripsBefore setting off on a long journey, it is
advisable to have your car checked over 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 gasoline 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 hard wear.
Check the battery charge.
Check the tires for tread pattern and air
pressure, including the compact spare
wheel.
Check the brakes.
Check all bulbs.
Check for the presence of the tool kit and
the jack in the car.
Recovery and/or
recycling of automotive
materialsA typical car consists of metals (65–75%),
plastics (10–14%), rubber (5%) and small
quantities of glass, wood, paper and tex-
tiles.
Some of these materials can be recycled,
while others can be recovered in chemical
processes for reuse in new products or as a
source of energy.
While the Saab 9-5 was still at the draw-
ing-board stage, Saab engineers were
giving serious consideration to how the
maximum quantity of materials could be
reclaimed from the car on its eventual
scrapping. To facilitate sorting, plastic parts,
for instance, have been marked to identify
the precise nature of the plastic.
Approximately 90% of the materials in the
car can be recycled or recovered, where
facilities exist.
Before the car is scrapped, all the oils and
other fluids that could pollute the environ-
ment should be recovered from the car. It
may be of interest in this context to learn that
the refrigerant used in the Saab 9-5’s ACC
systems (R134a) contains neither CFCs nor
any other chlorine compounds.
