Hyundai Elantra HD: Windshield defrosting and defogging
CAUTION - 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. In this case, set the mode selection knob or button
to the 
position and fan speed control
knob or button to the lower speed.
- For maximum defrosting, set the temperature control to the extreme right/hot position and the fan speed control to the highest speed.
- If warm air to the floor is desired while defrosting or defogging, set the mode to the floor-defrost position.
- Before driving, clear all snow and ice from the windshield, rear window, outside rear view mirrors, and all side windows.
- Clear all snow and ice from the hood and air inlet in the cowl grill to improve heater and defroster efficiency and to reduce the probability of fogging up inside of the windshield.
