Kia Rio: Defogging Logic / Auto defogging system

Auto defogging reduces the possibility of fogging up the inside of the windshield by automatically sensing the moisture inside the windshield and air flow toward the windshield can increase.

The auto defogging system operates when the AUTO mode is on.

This indicator illuminates when the auto defogging system senses moisture on the inside of the windshield and is activated.

If more moisture is in the vehicle, the auto defogging system addresses excess moisture on the inside of the windshield in stages as follows:

Step 1 : Operating the air conditioning
Step 2 : Outside air position
Step 3 : Blowing air flow 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 deactivate the auto defogging system, keep the front defroster button pressed longer than 3 seconds.

The “ADS OFF” symbol will be shown in the climate display to inform you that the system is deactivated.

To re-activate the auto defogging system again, follow the procedure mentioned above and the “ADS OFF” symbol will disappear.

If the battery has been disconnected or discharged, it resets to the auto defogging status.

✽ NOTICE
