Kia K900: Auto Defogging System
Auto Defogging reduces the probability of fogging up the inside of the windshield by automatically sensing the moisture of inside the windshield.
The Auto Defogging System operates when the heater or air conditioning is on.

This indicator illuminates when the Auto Defogging System senses moisture inside the windshield and the Auto Defogging System starts to operate.
If more moisture is in the vehicle, the higher steps operate as follow. For example if auto defogging does not defog inside the windshield at step 1 Outside air position, it tries to defog again at step 2 Blowing air toward the windshield.
Step 1 :Outside air position
Step 2 :Operating the air conditioning
Step 3 :Blowing air toward the windshield
Step 4 :Increasing air flow toward the windshield
If your vehicle is equipped with the auto defogging system, it is automatically activated when the conditions are met. However, if you would like to cancel the auto defogging system, press the front defroster button 4 times within 2 seconds while pressing the AUTO button.
The indicator will blink 3 times to notify you that the system is cancelled. To use the auto defogging system again, follow the procedures mentioned above.
If the battery has been disconnected or discharged, it resets to the auto defogging status.
