Defogging Windows To defog the windshield, turn all three control knobs to the far right. rn Air Conditioning System (OPTION) Air Conditioning Your system has three air conditioner settings. Before using your air conditioner on very hot days, open the windows long enough to let hot inside air escape.

This setting recirculates much of the air inside your vehicle so it maximizes your air conditioner's performance and your vehicle's fuel economy.

Your vehicle also has the flow-through ventilation system described later in this section. : The left knob sets the fan speed. To select the force of air you want, turn the knob.
