Windscreen defrosting and defogging
Windscreen 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 windscreen could cause the outer surface of the windscreen 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 whilst defrosting or defogging, set the mode to the floor-defrost position.
-
Before driving, clear all snow and ice from the windscreen, rear window, outside rear view mirrors, and all side windows.
-
Clear all snow and ice from the bonnet 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 windscreen.
