Operation Tips - Chevrolet Impala Limited 2014 Owner's Manual

8-4 Climate Controls
This mode helps to quickly heat or
cool the air inside the vehicle once
the temperature inside the vehicle is
equal to or better than the outside
temperature. It can be used to
prevent outside air and odors from
entering the vehicle. The
recirculation mode is not available in
outside air, floor, defog, or defrost
modes. If the button is selected
while in these modes, the indicator
flashes three times.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
1
(Rear Window Defogger): The
rear window defogger turns off
automatically after it has been
activated for 10 minutes. It can be
turned off manually, by pressing the
button again or by turning the
ignition to the LOCK/OFF position.
The rear window defogger can be
turned on again for additional
window clearing. The length of
defogger operation will increase if
the vehicle is being driven.
If equipped with heated outside
rearview mirrors, the mirrors heat to
help clear fog or frost from the
surface of the mirror when the rear
window defog button is pressed.
See Power Mirrors on page 2-14.
Do not drive the vehicle until all the
windows are clear.
Caution
Using a razor blade or sharp
object on the inside rear window
can damage the antenna or
defogger. Repairs would not be
covered by the vehicle warranty.
Do not stick anything to the rear
window.
Air Vents
Use the thumbwheel located below
or to the side of the outlet, to
change the direction of the air flow.

Operation Tips

Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
may block the flow of air into the
vehicle.
Use of non-GM approved hood
deflectors may adversely affect
the performance of the system.
Keep the path under the front
seats clear of objects to help
circulate the air inside the
vehicle more effectively.
