Hyundai Tucson: Climate Control Additional Features / Auto Defogging System on Models with Automatic Temperature Control

Auto defogging reduces the likelihood of fogging up the inside of the windshield by sensing moisture on the inside of the windshield.

The auto defogging system operates when the heater or air conditioning is on.

Information

The Auto Defogging system may not operate normally, when the outside temperature is below 14 °F (-10 °C).

When the Auto Defogging System operates, the indicator illuminates.

If high amount of humidity is detected in the vehicle, the Auto Defogging system is enabled.

The following steps are performed automatically:

Step 1) Air conditioning turns on and Fresh mode is selected.
Step 2) Defrost-level is selected.
Step 3) Fan speed is set to MAX.
