Keep the hood and front air inlet free of ice, snow or
any other
obstruction
(such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.
When
you
enter a vehicle in cold weather, turn the
fan control knob to the highest position for
a
few
moments before driving off. This helps clear the

chance of fogging the inside of your windows.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your
vehicle.
