Passenger Temperature Control - Buick 2005 Park Avenue Owner's Manual

At speeds above 30 mph (48 km/h), the defogger will
operate continuously until you press the REAR
button again. After 10 minutes of driving below 30 mph
(48 km/h), the defogger will turn off automatically. If
you need additional warming time, push the button
again. The system will then operate for five minutes
before going off by itself.
If your vehicle has heated outside rearview mirrors, the
mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defogger
button is pressed.
Notice: Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.

Passenger Temperature Control

If your vehicle has the passenger temperature control,
then the driver and the right front passenger can
select separate temperature settings. This feature
allows the front passenger to select a temperature that
is 5° F (3° C) warmer or cooler than the driver's
selected temperature.
The lever for this feature is located on the right side of
the instrument panel.
Slide the lever toward WARM for warmer air or toward
COOL for cooler air. Press OFF on the main climate
control system once to turn off the passenger's
temperature control.
When this lever is moved, the current inside temperature
will appear on the display for a few seconds, then the
outside temperature will appear.
