Hyundai Santa Fe: Climate control additional features / Auto defogging system

Hyundai Santa Fe (TM) 2019-2024 Owner's Manual / Convenience features / Climate control additional features / Auto defogging system

Auto defogging helps reduce the possibility of fogging up the inside of the windshield by automatically sensing the moisture on inside 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 will illuminate.

If a high amount of humidity is detected in the vehicle, the Auto Defogging System will be enabled. The following steps will be performed automatically:

Step 1) Air conditioning will turn ON.
Step 2) Air intake control will change to Fresh mode.
Step 3) Mode will change to defrost to direct airflow to the windshield.
Step 4) Fan speed will be set to MAX.

If the air conditioning is off or recirculation mode is manually selected while Auto Defogging System is ON, the Auto Defogging System indicator will blink 3 times to signal that the manual operation has been canceled.
