Auto Defogging System

Driving in the rain or in winter is always challenging. Bad weather impairs a driver’s vision – but that’s not all. Like the saying, “When it rains, it pours,” drivers have to contend with a slew of other factors in addition to the weather.

Foggy windows are annoying and potentially dangerous. Moisture inside a car is caused by the differences in temperature and humidity between the inside and outside of a car. Haze or fog can occasionally obstruct the driver’s visibility. However, it’s not a problem for drivers of Cadenza!

Kia Motors successfully developed an Auto Defogging System and installed the system in the Cadenza. The system removes moisture from the windows and controls humidity levels inside the cabin for maximum comfort.

On auto setting, wind is blown onto the windshield at the right temperature to remove moisture. A convenient feature is that the breeze can also be used to control the cabin temperature. A humidity sensor attached to the windshield and its control logic detect moisture on the window and automatically activate the A/C system to defog the windows without the driver having to press a button.

The auto defogging system found in competitor vehicles do not have the cabin temperature control function, which means the cabin can suddenly get hot when the system is turned on. The Cadenza though, ensures pleasant driving conditions as it removes the fog and controls the indoor temperature.
