Dual Automatic Climate Control System - Buick 2005 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 15 minutes after the button is
pressed, unless the ignition is turned to ACC or LOCK.
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: 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.
