In summer time your cars air conditioner is always on while you are driving. Here are some tips on how you canmake the most effecient use of it:- 1. For faster cooling on a hot day, travel with the windows open and the AC (fan set high) for a few minutes. This will drive out the hot air. Then shut the window and travel for a few minutes at the re-circulate position. then put the air supply in the normal (vent closed) position. Set fan slower too. 2. The higher the difference between internal and external temperature, the higher the fuel consumption. 3. Using the AC consumes just as much fuel as if you were travelling with open windows up to 10% more than with the windows closed and the AC turned off. 3. When not in use. turn on the AC at least once a week to prevent its refrigerant gas from leaking. 4. Prevent stale air caused by bacteria in the evaporator by switching off the AC 5 to 10 minutes before you leave the car. 5. And, last but not the least as far as possible park in the shade.
