B730A01FC-EAT Operation Tips
o To keep dust or unpleasant fumes from enter-
ing the car through the ventilation system, temporarily set the air intake control at "Recir- culation". Be sure to return the control to "Fresh" when the irritation has passed to keep fresh air in the vehicle. This will helpkeep the driver alert and comfortable.
o Air for the heating/cooling system is drawn in through the grilles just ahead of the wind- screen. Care should be taken that these are not blocked by leaves, snow, ice or other obstructions.
o To prevent interior fog on the windscreen, set
the air intake control to the fresh air ( ) position and fan speed to the desi-red posi- tion.
NOTE:When the A/C is operated continuously on the floor-defrost level (
) or defrost level
(), it may cause fog to form on the exterior
windscreen by the temperature differential. At this time set the air flow control to the face level position (
)and fan speed control to the
low position.
Use the heating/ventilation system to defrost or defog the windscreen: To remove the interior fog on the windscreen;
o Set the air flow control to the defrost (
)
position. (The A/C will be on automatically and it will be changed to "Fresh" mode.)
o Set the temperature control at the desired position.

FM reception
SSAR010A
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 high quality reproduction. How- ever, in some cases the signal coming to your vehicle is not 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. AM broadcasts can be received at greater dis- tances than FM broadcasts. This is because AM radio waves are transmitted at low frequency. 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.
FM broadcasts are transmitted at high frequency and do not bend to follow the earth's surface. Because of this, FM broadcasts generally begin to fade at short distances from the station. Also, FM signals are easily affected by buildings, moun- tains, 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 indi- cate radio trouble:
