Defogging And Defrosting; Rear Window Defogger - Chevrolet 2006 HHR Owner's Manual

Defogging and Defrosting

Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is used
properly. There are two modes to clear fog or frost from
your windshield and side windows. Use the defog mode
to clear the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog or frost
from the windshield more quickly. For best results, clear
all snow and ice from the windshield before defrosting.
Turn the right knob to select the defog or defrost mode.
-
(Defog): This mode directs approximately half of
the air to the windshield and the side window outlets and
half to the floor outlets. When you select this mode
the system runs the air conditioning compressor.
To defog the windows faster, turn the temperature
control knob clockwise to the warmest setting.
Recirculation mode is not available in defog mode.
0
(Defrost): This mode directs most of the air to the
windshield, with some air directed to the side window
outlets and the floor outlets. When you select this mode
the system runs the air conditioning compressor.
To defrost the windows faster, turn the temperature
control knob clockwise to the warmest setting.
Recirculation mode is not available in defog mode.

Rear Window Defogger

The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger will only work when the
ignition is in RUN.
<
(Rear): Press the button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible. An indicator light below
the symbol will come on to let you know that the
rear window defogger is activated.
The rear window defogger will turn off approximately
15 minutes after the button is pressed. If turned on
again, the defogger will only run for approximately
seven minutes before turning off. If turned on again, the
defogger will only run for approximately seven minutes
before turning off. If vehicle speed is greater than 50 mph
(80 km/h) and the rear defogger is active, it will remain on
as long as the speed is greater than 50 mph (80 km/h).
The defogger can also be turned off by pressing the
button again or by turning off the engine.
Notice: Do not use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs would not be
covered by your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything similar to
the defogger grid.
