Automatic Defogging System

~1min read

The automatic defogging system reduces the possibility of fogging on the inside of the windshield by automatically detecting moisture inside the windshield.

The automatic defogging system operates when the heater or air conditioner is on.

The automatic anti-fog system is activated when you select "Settings → Vehicle → Climate → Defog/Defrost Option → Automatic Anti-Fog System" from the settings menu on the infotainment system screen.

This indicator illuminates when the auto defog system detects humidity inside the windshield and is operating.

The automatic anti-fog system removes excess moisture inside the windshield in stages. For example, if the automatic defogging does not clear fogging inside the windshield in Step 1 (outside air position), it attempts to prevent fogging again in Step 2 (air conditioner operation).

Step 1: Outside air position
Step 2: Air conditioner operation
Step 3: Direct airflow toward the windshield
Step 4: Increase airflow toward the windshield

To cancel or reset the automatic defogging system

To cancel or set the automatic defogging system, press the front windshield defrost button for 3 seconds while the Engine Start/Stop button is ON.

The windshield defrost button indicator or the "ADS OFF" message will flash or display 3 times at 0.5-second intervals, and the system will be canceled or set.

CAUTION

Do not remove the sensor cover located on the upper end of the windshield on the passenger side. Damage to system parts may occur, which may or may not be covered by your vehicle warranty.
