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.
