I have an American 4.6 and I have no idea what they are talking about. lol I must be missing something.
Hmm, found this in the manual...
Auto defogging system (if equipped) Auto defogging reduces the probability of fogging up the inside of the windshield by automatically sensing the moisture of inside the windshield.
This indicator illuminates when the auto defogging system senses the moisture of inside the windshield and operates.
If more moisture is in the vehicle, the higher steps operate as follows. 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 : Blowing air toward the windshield
Step 3 : Increasing air flow toward the windshield
Step 4 : Operating the air conditioning
Step 5 : Maximizing the air conditioning
Defogging logic
To reduce the probability of fogging up the inside of the windshield, the air intake is controlled automatically according to certain conditions such as [pic] or [pic] position. To cancel or return the defogging logic, do the following.
1. Turn the ignition switch to the ON position.
2. Select the defrost position pressing defrost button ( ).
3. While holding the air conditioning button (A/C) pressed, press the air intake
control button at least 5 times within 3 seconds. The A/C display blinks 3 times with 0.5 second of interval. It indicates that the defogging logic is canceled or returned to the programmed status. If the battery has been discharged or disconnected, it resets to the defog logic status.
