Climate control Operating tips for heater and air conditioner J Cleaning ventilator grille Ventilator inlet grille Right hand drive vehicle Ventilator inlet grille HB0260 HB0261 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. J Efficient cooling after parking in direct sunlight 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. J Lubrication oil circulation in the refrigerant circuit 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. J Checking air conditioning system before summer season Check the air conditioner unit for refrigerant leaks, hose conditions, and proper operation each spring. This check is best performed by your SUBARU dealer. - CONTINUED - 4-23
