Front ventilator inlet grille Condenser
S _ 403896-W
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 SUN- LIGHT 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.
COOLING AND DEHUMIDIFY- ING IN HIGH HUMIDITY AND LOW TEMPERATURE WEATH- ER CONDITION s04ad05
Under certain weather conditions( high relative humidity, low temperatures, etc.) a small amount of water vapor emission from the air outlets may be noticed. This condition is normal and does not indicate any problem with the air conditioning system.
AIR CONDITIONER COMPRES- SOR SHUT-OFF WHEN ENGINE IS HEAVILY LOADED s04ad06
To improve acceleration and gas mileage, the air conditioner compressor is designed to temporarily shut off during air conditioner operation whenever the accelerator is fully depressed such as during rapid acceleration or when driving on a steep upgrade.
