(1) Park the vehicle in the shade. Parking in the hot sun will make the vehicle interior extremely hot, and it will require more to cool the interior.
If it is necessary to park in the sun, open the windows for the first few minutes of air conditioning operation to expel the hot air.
(2) Close the windows when the air conditioning is in use. The entry of outside air through open windows will reduce the cooling efficiency.
(3) Too much cooling is not good for the health. The inside air temperature should only be 5 to 6 C below the outside air temperature.
(4) When operating the system, make sure the air intake, which is located in front of the windscreen, is free of obstructions such as leaves. Leaves collected in the air-intake plenum may reduce air flow and plug the plenum water drains.
