Ventilation System - Buick 2001 Century Owner's Manual

Ventilation System

-
Your vehicle's flow through ventilation system
supplies outside air into the vehicle when it is moving.
Outside air will also enter the vehicle when the air
conditioning fan is running.
If the airflow seems very low when the fan is adjusted
to the highest setting regardless of the mode setting,
your passenger compartment air filter may need to be
replaced. See "Maintenance Schedule" or "Passenger
Compartment Air Filter" in the Index.
Adjust the direction
of airflow by moving
the vents.
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, adjust the
mode knob or button to FLOOR and the fan to the
highest speed for a few seconds before driving off.
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
For mild outside temperatures, when little heating
or cooling is needed, use VENT to direct outside air
through your vehicle.
