2003 SAAB 9-3 air conditioning

79 Instruments and controls
Manual climate-control
systemFresh air for the cabin is drawn in through an
inlet grille at the bottom edge of the wind-
shield. It passes through a filter before
reaching the climate control system and
delivery into the cabin. The air is evacuated
via openings in the parcel shelf. It is then led
through outlets on either side of the car
behind the rear bumper.
The incoming air is treated in three stages:
first it passes through a filter; it is then dehu-
midified and cooled; and finally, if required,
it is heated.
To optimize the performance of the A/C sys-
tem, all windows and the sunroof should be
shut.
To reduce potential misting on the insides of
the windows, the glass should be cleaned
with a quality glass cleaner. How often this
will need to be done depends on how clean
the air is - if there are smokers in the car, the
windows will need to be cleaned more fre-
quently.
The output of air is controlled by the fan
speed.
Temperature controlThe temperature of the incoming air can
be infinitely varied using the temperature
control.

82 Instruments and controlsAir ventsThe air vents swivel universally, so that air
can be directed as desired. In winter, for
instance, the outer vents can be directed
onto the door windows for enhanced
demisting.
The amount of air can be individually con-
trolled by the regulator on each vent. If you
wish to reduce the airflow, start by half-
shutting the vent in question.The air conditioning is combined with the
conventional climate control system and
is switched on by pressing the but-
ton, provided that the fan control is in
position 1-5.
The incoming air is treated in three stages:
first it passes through a filter; it is then dehu-
midified and cooled; and finally, if required,
it is heated.
The air conditioning can be used at outdoor
temperatures down to 32°F (0°C). It is not
necessary to disengage the air conditioning
manually as this is done automatically.
If the engine coolant gets too hot, the A/C
compressor will be turned off and the follow-
ing message will be shown on the Saab
Information Display (SID):
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.
When the button is pressed, the reg-
ular air intake will be closed. In this mode,
the air inside the cabin is recirculated.
Use recirculation when you wish for rapid
cooling at very high outside temperatures.
Switch the air conditioning (A/C) on first.
If necessary, recirculation can be switched
on manually to avoid unpleasant air from
entering the car.
Only use recirculation for a short period
of time at temperatures lower than 50°F
(+10°C), such as to avoid unpleasant air.
Mist or ice may otherwise form on the
windows.
Air conditioning (A/C)A/C off due to high engine
temperature.

218 Car careCleaning and caring for leather
upholsteryThe principal reason for treating leather
upholstery is to maintain its elegant appear-
ance and to provide it with a protective film.
Discolouration caused by dust and wear
mainly affects the lighter shades, although
this is not detrimental to the leather, indeed,
the patina resulting from use is often consid-
ered desirable in leather. But if the leather is
allowed to become too grubby, it can start to
look shabby.
The leather upholstery should be cleaned
and reconditioned twice a year in conjunc-
tion with spring and autumn inspections. In
very warm, dry climates the leather may
need more regular reconditioning. Recom-
mended conditioner – Saab Leather Care
Lotion.
Do not use unknown harsh polishing
agents, cleaning agents, sprays, coarse
soap or hot water.
Textile carpetingTextile carpeting should be vacuum
cleaned regularly. Carpeting can also be
cleaned using a brush or sponge and carpet
shampoo.
For safety reasons, vacuum cleaners that
are not earthed (grounded) must not be
used out of doors.Engine bayThe engine bay should be cleaned with an
engine degreasant and rinsed with hot
water. The headlights must be covered
over. Do not use a pressure washer.
Do not use petrol as a cleaning agent or sol-
vent when carrying out repairs or mainte-
nance. Saab recommends the use of envi-
ronmentally-friendly degreasants.
WashingThe bodywork must be washed frequently.
When the car is new, the body should be
washed by hand using plain cold water and
a clean, soft brush through which the water
flows. Automatic carwashes should be
avoided when the car is new.
After 5–6 months the paintwork will have
hardened. To facilitate cleaning, a suitable
detergent can be added to the water, which
should be lukewarm.
Remove any bird droppings without delay,
as these can discolour the paintwork and
prove difficult to polish out. Lay a wad of wet
paper on the patch of dirt and leave it for a
minute or so. It will then be easy to wash off
the dirt.
Use a soft cloth moistened with white spirit
to remove splashes of tar or asphalt. Do not
use strong cleaners, as these can dry out
the paintwork.
The underside of the car also needs wash-
ing regularly, and this should be done extra NOTICEDo not use alcohol-based cleaners on the
plastic lenses of the front or rear lights, as
these can cause a crackling effect on the
lenses.
The door mirrors should be folded in
before the car enters an automatic car
wash.

224 Car careAir conditioning (A/C)
TroubleshootingIf a fault occurs in the A/C system, there are
a number of checks you can perform your-
self. If the fault persists, however, have the
system checked at a Saab dealer.
Note:
When the A/C system is running, the intake
air is dehumidified. The resultant condensa-
tion that forms on the evaporator is drained
off under the car. When the car is parked,
this may result in a small puddle forming on
the ground. The warmer the air and the
higher the relative humidity, the more con-
densation will be produced.
Inadequate coolinga Check that the controls for temperature
and air distribution are correctly set; see
"Manual climate-control system" on
page 79.
b Check that the condenser (in front of the
radiator) has not become clogged with
dirt and insects.
c Make sure that the compressor drive
belt does not slip (see page 185).
d Check the fuses for the ventilation fans
and compressor (see page 201).
WARNING
 All repairs and adjustments to the A/C
system must be carried out at a Saab
dealer authorized for this kind of work.
 The A/C system is pressurized. Do not
break any connections or undo A/C
system components.
 Escaping gas can cause eye injury or
other personal injury.NOTICE The A/C system is designed for use
with R134a refrigerant.
 Refrigerant handling requires special
equipment and special procedures for
charging and draining the system.
 Never mix R 134a with other refriger-
ants.
