B740D02Y-AATOperation Tipso If the interior of the car is hot when you first
get in, open the windows for a few minutes
to expel the hot air.
o When you are using the air conditioning
system, keep all windows closed to keep hot
air out.
o When moving slowly, as in heavy traffic, shift
to a lower gear. This increases engine speed,
which in turn increases the speed of the air
conditioning compressor.
o On steep grades, turn the air conditioning off
to avoid the possibility of the engine over-
heating.
o During winter months or in periods when the
air conditioning is not used regularly, run the
air conditioning once every month for a few
minutes. This will help circulate the lubri-
cants and keep your system in peak oper-
ating condition.

STEREO SOUND SYSTEMB750A02A-AATHow Car Audio Works
AM broadcasts can be received at greater
distances than FM broadcasts. This is because
AM radio waves are transmitted at low frequen-
cies. These long, low frequency radio waves
can follow the curvature of the earth rather than
travelling straight out into the atmosphere. In
addition, they curve around obstructions so that
they can provide better signal coverage. AM and FM radio signals are broadcast from
transmitter towers located around your city.
They are intercepted by the radio antenna on
your car. This signal is then received by the
radio and sent to your car speakers.
When a strong radio signal has reached your
vehicle, the precise engineering of your audio
system ensures the best possible quality repro-
duction. However, in some cases the signal
coming to your vehicle may not be strong and
clear. This can be due to factors such as the
distance from the radio station, closeness of
other strong radio stations or the presence of
buildings, bridges or other large obstructions in
the area.FM broadcasts are transmitted at high frequen-
cies and do not bend to follow the earth's
surface. Because of this, FM broadcasts gen-
erally begin to fade at short distances from the
station. Also, FM signals are easily affected by
buildings, mountains, or other obstructions.
These can result in certain listening conditions
which might lead you to believe a problem exists
with your radio. The following conditions are
normal and do not indicate radio trouble: Ionosphere
