Hyundai Sonata: Convenient features of your vehicle / 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.
- 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, side 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 the inside of the windshield.
NOTICE
If the engine temperature is still cold after starting, then a brief engine warm up period may be required for the vented air flow to become warm or hot.
