To Cool with A/C (optional on DX) To cool the car down quickly, start the engine, turn the fan to high, push the A/C button and open the windows briefly. Then close the windows, slide the temperature lever all the way to the left or turn the temperature control dial counterclockwise all the way, select the position and push the button on, so inside air will recirculate to the air conditioner for maximum cooling. When the interior has cooled sufficiently, switch the fan to the desired speed, then change to the setting to direct fresh (outside) air to the air conditioner. [DX] [LX/EX] When using the air conditioner in heavy traffic, or while driving up long hills, watch the coolant temperature gauge: if the needle moves near the " H " end of the scale, turn the air conditioner off by pushing the A/C button; leave it off until the needle goes back into the middle of the scale.
