2004 SAAB 9-3 heater

105 Instruments and controls
The system uses four sensors:
 Outside air temperature sensor
 Cabin air temperature sensor
 Sun sensor
 Blended air temperature sensors (located
in the heater unit and the outer panel vent
duct).
The sun sensor is located centrally on the
top of the fascia.
Note:
If the sun sensor is covered, the ACC
system will not be able to regulate the cabin
climate as intended, especially in strong
sunshine.Condensation waterWhen the A/C compressor is on, the incom-
ing air is dehumidified. The resulting con-
densation water is drained away through an
outlet under the car.
It is therefore perfectly normal for water to
be seen dripping from this outlet when the
car is parked. The warmer the ambient air
and the higher the humidity, the more con-
densation will form.

174 Starting and drivingengine wear is at its greatest during this
period. Drive off as soon as possible after
starting the engine and avoid high engine
speeds.
 Drive as smoothly and thoughtfully as
possible. Match your driving to the
prevailing traffic conditions.
 Driving in a low gear gives rise to higher
fuel consumption than driving in a high
gear because of the higher engine speed
for any given road speed. Always shift up
as soon as traffic conditions allow and
drive in the highest gear as much as
possible.
 Check the tire pressure once a month.
Incorrect tire pressure increases tire
wear. It is preferable for the tire pressure
to be slightly high than too low. Under-
pressure increases fuel consumption. Check the fuel consumption regularly.
Increased fuel consumption can indicate
that something is wrong and that the car
needs to be checked at a Saab dealer.
Practical road tests have demonstrated that
substantial savings in fuel consumption can
be made if the above advice is followed.
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).
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 60–70°F (+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,
electric cabin heater that is not in use, store
this in the trunk.
WARNING
Never switch off the engine while driving
as the effect of the brakes and power
steering will be greatly reduced.
