Dual Automatic Climate Control System - Buick 2006 LaCrosse Owner's Manual

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<
(Rear): Press the button to turn the rear window
defogger on or off. An indicator light below the button will
come on to let you know that the rear window defogger
is activated.
The rear window defogger will only work when the
ignition is in run. The rear window defogger will stay
on for approximately 20 minutes after the button
is pressed, unless the ignition is turned to ACCESSORY
or RUN. If turned on again, the defogger will only run
for approximately 20 minutes before turning off.
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.
