Dual Automatic Climate Control System - Buick Lucerne 2007 Owner's Manual

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 is on. See Outside
Automatic Dimming Heated Mirror on page 136
for more information.
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.
Dual Automatic Climate Control
System
With this system you can control the heating,
cooling, and ventilation for your vehicle.
If your vehicle has the remote start feature and it
is activated, the climate control system will
heat and cool the inside of the vehicle, using the
previous system settings before the vehicle
was turned off. The rear window defogger will be
turned on by the climate control system when
it is cold outside. If the vehicle has heated seats,
they will also turn on. Cooled seats are not
activated during a remote start. Normal operation
of the system will return after the key is turned
to the RUN position. See Remote Keyless
Entry (RKE) System Operation on page 96 for
more information.
Automatic Operation
