B670C02FC-GAT Air Intake Control With the "Fresh" mode selected, air enters the vehicle from the outside andis heated or cooled according to the function selected. With the "Recirculation" mode selected, air from within the passenger compart- ment will be drawn through the heatingsystem and heated or cooled according to the function selected. NOTE:
o It should be noted that prolonged
operation of the heating in "Recir- culation" mode will increase to fogging of the windshield and sidewindows and the air within the passenger compartment will be- come stale. In addition, prolongeduse of the air conditioning with the "Recirculation" mode selected may result in the air within thepassenger compartment becom- ing excessively dry.
o When the ignition switch is turned "ON" the air intake control willchange to ( ) mode (regardless of switch position). This is normaloperation.
This is used to select fresh outside airor recirculating inside air. To change the air intake control mode, (Fresh mode, Recirculation mode) pushthe control button. FRESH MODE
( ) :
The indicator light on the button goes off when the air intake control is in fresh mode. RECIRCULATION MODE ( ):
The indicator light on the button is illuminated when the air intake control is in recirculation mode. HFC2067
For normal heating operation, set the air intake control to the "Fresh" position and the air flow control to "Floor". For faster heating, the air intake control should be in the "Recirculation" posi-tion. If the windows fog up, move the air flow control to the "Def" (defroster) position. (The A/C will turn on automatically and "Fresh" mode will be activated.) For maximum heat, move the tempera- ture control to "Warm".

o To keep dust or unpleasant fumes
from entering the car through the ventilation sys-tem, temporarily set the air intake control at "Recircula-tion". Be sure to return the control to "Fresh" when the irritation has passed to keep fresh air in the ve-hicle. This will help keep the driver alert and comfortable.
o Air for the heating/cooling system is
drawn in through the grilles just aheadof the wind-shield. Care should be taken that these are not blocked byleaves, snow, ice or other obstruc- tions.
o To prevent interior fog on the wind-
shield, set the air intake control tothe fresh air ( ) position, fan speed to the desired position, turn on the airconditioning system, and adjust tem- perature control to desired tempera- ture.

90AIR CONDITIONER FILTER (IN FRONT OF BLOWER UNIT)
B740D01A-AAT Operation 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 condition-
ing system, keep all windows closedto keep hot air out.
o When moving slowly, as in heavy
traffic, shift to a lower gear. Thisincreases engine speed, which in turn increases the speed of the air conditioning compressor.
o On steep grades, turn the air condi- tioning off to avoid the possibility ofthe engine over-heating.
o During winter months or in periods when the air conditioning is not usedregularly, run the air conditioning onceevery month for a few minutes. This will help circulate the lubricants and keep your system in peak operatingcondition. B760A03FC-GAT (If Installed) The air conditioner filter is located in front of the blower unit behind the glove box. It operates to decrease pollutants from entering the car.To replace the air conditioner filter, refer to the page 6-26.
CAUTION:
o Replace the filter every 20,000 km (12,000 miles) or once a year. If the car is being driven in severe con-ditions such as dusty, rough roads, more frequent air condi- tioner filter inspections andchanges are required.
o When the air flow rate is decreased,
it must be checked at an autho-rized dealer.

B750A03L
Obstructed area
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 isthen received by the radio and sent to your car speakers. When a strong radio signal has reachedyour vehicle, the precise engineering of your audio system ensures high quality reproduction. However, in some casesthe signal coming to your vehicle may not be strong and clear. This can be due to factors such as the distance from theradio station, closeness of other strong radio stations or the presence of build- ings, bridges and other large obstruc-tions in the area. Iron bridges
AM broadcasts can be received atgreater distances than FM broadcasts. This is because AM radio waves are transmitted at low frequencies. These long, low frequency radio waves can follow the curvature of the earth ratherthan travelling straight out into the at- mosphere. In addition, they curve around obstructions so that they canprovide better signal coverage. FM broadcasts are transmitted at highfrequencies 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 bybuildings, mountains, or other obstruc- tions. These can result in certain listen- ing conditions which might lead you tobelieve a problem exists with your ra- dio. The following conditions are normal and do not indicate radio trouble:

B750A05LB750B02Y-AAT Using a cellular phone or a two- way radio When a cellular phone is used inside the vehicle, noise may be producedfrom the audio equipment. This does not mean that something is wrong with the audio equipment. In such a case,use the cellular phone at a place as far as possible from the audio equipment.
!
CAUTION:
When using a communication sys- tem such as a cellular phone or a radio inside the vehicle, a separateexternal antenna must be fitted. When a cellular phone or a radio set is used with an internal antenna alone, itmay interfere with the vehicle's elec- trical system and adversely affect safe operation of the vehicle.
WARNING:
Don't use a cellular phone when youare driving, you must stop at a safeplace to use a cellular phone.
o Fading - As your car moves away
from the radio station, the signal will weaken and sound will begin to fade. When this occurs, we suggest that you select another stronger station.
o Flutter/Static - Weak FM signals or large obstructions between the trans-mitter and your radio can disturb the signal causing static or flutteringnoises to occur. Reducing the treble level may lessen this effect until the disturbance clears. o Station Swapping - As an FM signal
weakens, another more powerful sig- nal near the same frequency may begin to play. This is because your radio is designed to lock onto the clearest signal. If this occurs, selectanother station with a stronger sig- nal.
o Multi-Path Cancellation - Radio sig- nals being received from several di-rections can cause distortion or flut- tering. This can be caused by adirect and a reflected signal from the same station, or by signals from two stations with close frequencies. Ifthis occurs, select another station until the condition has passed.
