Outlet Adjustment; Operation Tips; Rear Window Defogger - Pontiac GRANDAM 2004 Owner's Manual

1
FRONT (Defrost): This mode directs most of the
air to the windshield, with some air directed to the floor
outlets. In this mode, the system will automatically turn
off recirculation and run the air-conditioning compressor,
unless the outside temperature is at or below freezing.
Recirculation cannot be selected while in the defrost
mode. Do not drive the vehicle until all the windows
are clear.

Rear Window Defogger

The rear window defogger uses a warming grid to
remove fog of frost from the rear window.
<
REAR: Press this button to turn the rear window
defogger on or off. An indicator light above the
button will come on to let you know that the rear window
defogger is activated. Be sure to clear as much snow
from the rear window as possible.
The rear window defogger will turn off approximately
10 minutes after the button is pressed. If turned on again,
the defogger will only run for approximately five minutes
before turning off. The defogger can also be turned off by
pressing the button again or by turning off the engine.
Notice: Don't use anything 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. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.

Outlet Adjustment

Use the louvers on the air outlets to change the
direction of the airflow.

Operation Tips

•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
•
Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
•
When an objectionable odor outside the vehicle is
encountered, use the MAX mode, with the
temperature knob at a comfortable setting to
prevent the odor from entering the vehicle through
the ventilation system. This can be helpful when
driving through a long tunnel with poor ventilation.
However, extended usage of this mode in cold
or cool weather can cause window fogging.
