Operating tips for heater and air conditioner
Cleaning ventilator grille
HB5019BC
Always keep the front ventilator inlet grille free of snow, leaves, or oth-
er 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
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
