CADILLAC DEVILLE 2005 8.G Owners Manual

Manual Operation
yMODEz:Pressing the MODE switch and changing
the mode cancels automatic operation and places the
system in manual mode. Press AUTO to return to
automatic operation.
To change the current mode, select one of the following:
F(Vent):This mode directs air to the instrument
panel outlets.
*(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets.
Some air may be directed toward the windshield.
In automatic operation, cooler air is directed to the upper
outlets and warmer air to the oor outlets.
7(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets, for the side windows, and a little air directed to
the windshield.
The MODE switch can also be used to select the
oor/defog mode. Information on defogging and
defrosting can be found later in this section.
y9z(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and places the system in manual
mode. Press AUTO to return to automatic operation.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment air lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-36
andScheduled Maintenance on page 6-4.
?(Recirculation):This mode keeps outside air
from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or
to help heat or cool the air inside your vehicle more
quickly. Press this button to turn the recirculation mode
on or off. When the button is pressed, an indicator
light will come on. The air-conditioning compressor also
comes on.
Driver’s Temperature Knob:Press this knob to turn
the entire climate control system on or off. Turn this
knob clockwise or counterclockwise to manually
increase or decrease the temperature inside your
vehicle.
3-31

yPASS TEMPz(Passenger’s Temperature):
Press this switch to turn the passengers’ climate control
systems on. Press this switch to manually increase
or decrease the temperature for the front passenger.
PASS OFF (Passenger’s Climate Control):Press this
button to turn all passenger climate control systems off.
If the passenger’s temperature switch is turned off, the
driver’s temperature knob will control the temperature for
the entire vehicle.
A/C (Air Conditioning):Press this button to override
the automatic system and turn the air-conditioning
system on or off. When in AUTO the air-conditioning
compressor will come on automatically, as necessary.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.For quick cool down on hot days:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select A/C.
4. Select the coolest temperature.
5. Select the highest fan speed.
6. Open all outlets.
Using these settings together for long periods of time
may cause the air inside your vehicle to become too dry.
To prevent this from happening, after the air in your
vehicle has cooled, turn the recirculation mode off.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
If your vehicle has the memory option, it can be used to
recall your climate control settings. For more information,
seeClimate Controls Personalization on page 3-39.
3-32

Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside your vehicle, then uses the
information to maintain the selected temperature by
initiating needed adjustments to the temperature, the fan
speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
middle of the instrument panel, near the windshield,
or the system will not work properly.There is also a sensor located behind the front grill.
This sensor reads the outside air temperature and helps
to maintain the temperature inside the vehicle.
Any cover on the front of the vehicle could cause a
false reading in the temperature.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear fog
from your windshield. Use the oor/defog mode to
clear the windows of fog or moisture and warm
the passengers. Use the defrost mode (FRONT) to
remove fog or frost from the windshield more quickly.
yMODEz:Press this button until the oor/defog
symbol appears on the display.
.(Floor/Defog):This mode directs the air equally
between the windshield and the oor outlets. When you
select this mode, the system turns off recirculation
and runs the air-conditioning compressor unless
the outside temperature is at or below freezing.
The recirculation mode cannot be selected while in
the oor/defog mode.
3-33

1FRONT (Defrost):Pressing FRONT directs most of
the air to the windshield and the side window outlets, with
some air directed to the oor outlets. In this mode, the
system will automatically turn off recirculation and run
the air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode. Do not drive the
vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in ON.
=REAR:Press this button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible.
The rear window defogger will turn off approximately
10 minutes after the button is pressed. If turned on
again, the defogger will only run for approximately
ve minutes before turning off. The defogger can also
be turned off by pressing the button again or by turning
off the engine.The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when the
REAR 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.
Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airow. Use the thumbwheel
located next to the outlets to turn them on and off.
Operation Tips

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

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they are working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Follow this manual’s
advice. Waiting to do repairs can be costly – and even
dangerous. So please get to know your warning
lights and gages. They are a big help.
Your vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-57for
more information.
