Rear Window Defogger; Ventilation System - Chevrolet 2000 Lumina Owner's Manual

Rear Window Defogger

The rear window defogger will turn itself off after about
10 minutes. If you turn it on again, the defogger will
only run for about five minutes before turning off. You
can also turn it off by turning off the ignition or pressing
the button again.
Do not attach anything like a temporary vehicle license
or decal across the defogger grid.
The rear window defogger
uses a warming grid to
remove fog from the rear
window. Press the area
labeled PUSH to turn the
defogger on.
NOTICE:
Don't use a razor blade or something 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 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.
