Hyundai Equus: Windshield defrosting and defogging

WARNING - Windshield heating

Do not use the or
position during cooling operation
in extremely humid weather. The difference between the temperature of the outside air and that of the windshield could cause the outer surface of the windshield to fog up, causing loss of visibility could cause an accident resulting in serious injury or death. In this case, set the mode selection knob or button to the position and fan speed control knob
or button to a lower speed.

• For maximum defrosting, set the temperature control to the extreme right/hot position and the fan speed control to the highest speed.

• Before driving, clear all snow and ice from the windshield, rear window, outside rear view mirrors, and all side windows.
