Ventilation System - Pontiac 2000 Grand Prix Owner's Manual

Do not attach anything like a temporary vehicle license
or decal across the defogger grid.
NOTICE:
Don't use a razor blade or anything else sharp on
the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.

Ventilation System

Adjust the direction of airflow by moving the
louvered vents.
-
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.
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 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.
