& Cleaning Ventilator Grille s04ad01
1 Front ventilator inlet grille 2 Condenser
Always keep the front ventilator inlet grille free of snow , leaves , or other obstructions to ensure efficient heating and defrosting . Since the condenser is located in front of the radiator , this area should be kept clean because cooling performance is impaired by any accumulation of insects and leaves on the condenser .
& Efficient Cooling after Parking in Direct Sunlight s04ad02
After parking in direct sunlight , drive with the windows open for a few minutes to allow outside air to circulate into the heated interior . This results in quicker cooling by the air conditioner . Keep the windows closed during the operation of the air conditioner for maximum cooling efficiency .
& Lubrication Oil Circulation in the Refrigerant Circuit s04ad03
Operate the air conditioner compressor at a low engine speed ( at idle or low driving speeds ) a few minutes each month during the off-season to circulate its oil .
& Checking Air Conditioning System before Summer Season s04ad04
Check the air conditioner unit for refrigerant leaks , hose conditions , and proper operation each spring . Have the air conditioning system checked by your SUBARU dealer .
& Cooling and Dehumidifying in High Humidity and Low Temperature Weather Condition
