Subaru Outback (BR): Cleaning ventilator grille

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.

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.
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.
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.
