For dehumidified heating:
o Turn on the fan control switch.
o Turn on the air conditioning switch. The air
conditioning indicator light should come on
at the same time.
o Set the air intake control to "Fresh" mode
( ).
o Set the air flow control to "Face".
o Adjust the fan control to the desired speed.
o For more rapid action, set the fan at one of
the higher speeds.
o Adjust the temperature control to provide
the desired amount of warmth.
B740D01A-AATOperation Tips
o 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 operat-
ing condition.
o Adjust the fan control to the desired speed.
For greater cooling, turn the fan control to
one of the higher speeds or temporarily
select the "Recirculation" position on the air
intake control.B740B01S-AAT

(20,000 km) or once a year. If the car is
being driven in severe conditions such
as dusty, rough roads, more frequent
air filter inspections and changes are
required.
o When the air flow rate is suddenly de-
creased, it must be checked at an autho-
rized dealer.
o If your vehicle is not equipped with this

AM reception
AM broadcasts can be received at greater
distances than FM broadcasts. This is be-
cause AM radio waves are transmitted at low
frequencies. These long, low frequency radio
waves can follow the curvature of the earth
rather than travelling straight out into the atmo-
sphere. In addition, they curve around obstruc-
tions so that they can provide better signal
coverage.FM broadcasts are transmitted at high fre-
quencies 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:

FM reception
SSAR010A
AM and FM radio signals are broadcasted 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 high quality reproduction. How-
ever, 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.
