2000 SAAB 9-3 radio antenna

107 Saab 9-3 Audio System
Multipath interference When the radio waves from an FM transmit-
ter collide with a large building, for example,
they will be reflected so that they reach the
car antenna slightly later than the direct
waves. This is referred to as multipath dis-
tortion. The effect is liable to be blamed
upon malfunctions in the radio. Antenna The antenna of the Audio System is motor-
ized.
Saab 9-3 Viggen Coupé and 5-door: The
antenna is located on the roof.
For the cleaning of the motorized antenna,
see the section headed "Washing", page
201.
Shadow effect Because FM radio waves travel in straight
lines from the transmitter, a shadow effect
can occur when tall buildings or hills
obstruct the interference path from the
transmitter to the car.
Sources of FM interference Interference to FM reception can be caused
by the electrical systems in other vehicles,
particularly if the signal from the transmitter
is weak.
To maintain good radio reception do not tint
the rear windshield, particularly with film
containing small metal flakes.
NOTERemove the antenna if you wash the car
in a car wash, to avoid it being damaged.

108 Saab 9-3 Audio SystemCross-modulation When the radio is tuned to a weak transmit-
ter in the vicinity of a stronger one, the car’s
antennas will receive signals from both.
Such interference is apparent when the
unwanted broadcast can be heard faintly in
the background.
Radio waves, FM/AM FM radio waves radiate in straight lines from
the transmitter. Because such waves do not
follow the curvature of the Earth, their
strength becomes weaker the further they
travel. That is why a large number of trans-
mitters are needed to provide good recep-
tion.
AM waves, on the other hand, are reflected
off the ionosphere, thus greatly extending
their range.
Sources of AM interference AM reception is prone to interference, e.g.
from electrical systems on other vehicles,
high-tension power lines and lightning.

110 Saab 9-3 Audio SystemMobile phones and
communications radios Mobile phones and communications radios
that do not have a separate external
antenna radiate an electromagnetic field
inside the car.
Saab therefore recommends that a car
phone/radio transmitter should always be
connected to an external antenna.
An external antenna also provides
improved transmission/reception and a
greater range.
Mobile phones and communications radios
that are not supplied as standard equipment
by Saab can interfere with the car’s electri-
cal system and cause misleading fault
codes to be generated.
Fault codesThe Audio System has a built-in diagnostics
function. If a fault is detected, a fault code is
generated to help dealer technicians to
diagnose the fault. Below is an example of
a fault code that you might be able to rectify
yourself.
Adjusting the frequency steps
North America/Europe If the car is taken from Europe to North
America, the radio’s frequency steps will
need to be adjusted.
 With the radio off, press and hold SEEK
(mid-segment) and switch the radio on at
the same time.
The station presets will be cancelled and
replaced by preset frequencies.
WARNING
The electromagnetic field inside the car
can be detrimental to your health. NOTEThe electromagnetic field can cause
interference with other electrical systems
in the car, such as the Audio System.
WARNING
Always consult an authorized Saab
dealer for installation guidance.
If you feel that any of the warnings or fault
indications are unclear, have the equip-
ment checked by an authorized Saab
dealer. NOTEGreat care should be exercised in trying
to rectify a fault. If you are at all unsure,
contact an authorized Saab dealer.

202 Car care
Waxing and polishingDo not wax a new car during the first three
or four months. In fact, there is no need to
polish the car before the paintwork has
started to go dull through oxidation. Other
than in exceptional cases, do not use abra-
sive polishes containing a cutting agent on
a new car. Always wash the car thoroughly
before waxing or polishing.
Touching up the paintDamaged paintwork should be treated as
soon as it is discovered: the longer it is left,
the greater the risk of corrosion. The
anti-perforation warranty does not cover
corrosion resulting from untreated defects.
Paintwork damage sustained in a collision is
usually extensive and can only be properly
restored by professionals.
However, you can repair small scratches
and stone-chip damage yourself. The nec-
essary tools and materials, such as primer,
touch-up paint and brushes, are available
from your Saab dealer.
In the case of minor flaws in the paintwork,
where the metal has not been exposed and
an undamaged layer of paint remains,
touch-up paint can usually be applied
directly, after any dirt has been scraped
away using a pointed knife.
If corrosion has already set in, e.g. as a
result of stone-chip damage, use a pointed
knife to scrape off all surface rust. If possi-
ble, the damaged area should be taken
back to the bare metal. The metal should
then be primed with two thin coats of primer
applied by brush.
After the primer has dried, apply several thin
layers of topcoat enamel until the surface of
the repaired area is flush with the surround-
ing paintwork.
Stir both primer and touch-up enamel thor-
oughly before use and allow each coat to
dry before applying the next.
NOTE Try your brakes on leaving a car wash.
Wet brake discs reduce the braking
effect.
 Turn off the radio before entering an
automatic car wash so the power
antenna mast does not get damaged.
 Clean the rod of the electrically pow-
ered antenna about once a month with
a clean, dry rag.
IMPORTANT! Use no oil, nor any sili-
cone-based cleaning product.
 Fixed antennas must be removed
when going through an automatic car
wash.
Saab 9-3 Viggen, Coupé and
5-door: If you wash the car in an auto-
matic car wash, you must first remove
the roof-mounted antenna, otherwise
it will be damaged.
 On Covertible models with OnStar,
fold down the cellular antenna
mounted on the windshield before
entering a car wash to avoid damage
to the antenna or convertible top.
