<bot>: The best way to keep a car cool in hot weather is to open up all of the windows and turn on the air conditioning. You can also roll down your windows slightly if you are parked in a shaded area, or use an electric fan if available. Additionally, make sure that the tires are properly inflated and that there is plenty of ventilation for the engine.
