Ventilation Tips
D Keep the hood and front air inlet free of ice, snow or
any other obstruction such as leaves. The heater and
defroster will work better, reducing the chance of
fogging your windows.
D In cool damp weather, minimize your use of
recirculation to reduce the chance of fogging
your windows.
D When you enter a vehicle with the standard system
in cold weather, select floor mode to supply air
through the floor outlets. Then turn the fan on high
for a few moments before driving away. This will
blow moist air from the intake outlets toward the
floor, not the windshield. It reduces the chance of
fogging your windows. If you have the electronic
system, the AUTO setting will do this for you.
Manual operation of the electronic system in the
floor mode will also supply air through the
floor outlets.
D Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
