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 far better, reducing the
chance of fogging the inside of your windows.
D
When you enter a vehicle in cold weather, turn
the fan to HI for a few moments before driving.
This helps clear the intake ducts of snow and
moisture, and reduces the chance of fogging the
inside of your windows.
D
Keep the air path under the front seats clear of objects.
This helps air to circulate throughout your vehicle.
D
The use of hood air deflectors may adversely affect the
performance of the heating and air conditioning system.
