air conditioning CADILLAC XLR V 2006 1.G Owners Manual

Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode,
the air-conditioning compressor and the fan speed.
AUTO will appear on the display.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70°F (21°C) and 80°F (27°C). An initial
setting of 73°F (23°C) is suggested.
Choosing the warmest or coldest temperature
setting will not cause the system to heat or cool
any faster. If you set the system at the warmest
or coldest temperature setting, the system will
remain in manual mode at that temperature and
it will not go into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will start
out blowing air at the oor but may change modes
automatically as the vehicle warms up to maintain
the chosen temperature setting. The length of time
needed for warm up will depend on the outside
temperature and the length of time that has elapsed
since your vehicle was last driven.3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature,
if necessary.
You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Controls
and Displays on page 3-64for more information.
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.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.
Manual Operation
wPWRx(Power/Temperature):Press the PWR
button on the left side of the climate control panel to turn
the entire climate control system on or off. Press the
up or down arrow on the switch to manually increase or
decrease the temperature inside the vehicle.
3-42

Press the PWR button on the right side of the climate
control panel to turn the passenger’s climate control
system on or off. Press the up or down arrow on
the switch to manually increase or decrease the
temperature for the passenger.
If the passenger’s PWR button is off, the driver’s
temperature switch controls the temperature for the
entire vehicle.
«9ª(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 3-47
andScheduled Maintenance on page 7-4.
ªN«(Mode):Pressing the switch and changing
the mode cancels automatic operation and places the
system in manual mode. Press the AUTO button to
return to automatic operation.To change the current mode, select one of the following:
H(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.
In automatic operation, cooler air is directed to the
upper outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed to the side window
outlets, and a little air directed to the windshield.
The mode switch can also be used to select the defog
mode. Information on defogging and defrosting can
be found later in this section.
A/C OFF (Air Conditioning):Press this button to turn
off the air conditioning compressor. Press AUTO to
return to automatic operation. The compressor cannot
be turned off in either the defrost or oor/defog mode.
3-43

((Heated/Cooled Seat):Press this button to turn the
feature on. The button on the left controls the driver’s
seat and the button on the right controls the passenger’s
seat. Each press of the button will take you to a
different setting. The settings available in order are
HI HEAT, LO HEAT, OFF, HI COOL, LO COOL
and OFF. You will be able to feel the temperature
change in a few minutes.
The feature will automatically turn off when the vehicle
is turned off.
?(Recirculation):Press this button to turn the
recirculation mode on or off. The air-conditioning
compressor also comes on. 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 cool the air inside your vehicle more quickly.
Recirculation is not available in defrost or oor/defog
modes.
Using recirculation 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.
Sensors
There are sensors to measure the temperature and
sun’s effect on passenger comfort.
The solar sensor on your vehicle monitors the solar
radiation then uses the information to maintain the
selected temperature when operating in AUTO mode 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 on
the top of the instrument panel near the windshield
or the system will not work properly.
There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps maintain the temperature inside the vehicle.
The outside temperature will be displayed in the
navigation system only when the engine is running.
Any cover on the front of the vehicle could give a false
reading of the temperature.
3-44

If the outside temperature goes up, the display
temperature will not change until:
The vehicle’s speed is above 10 mph (16 km/h)
for ve minutes.
The vehicle’s speed is above 32 mph (51 km/h)
for two and one-half minutes.
These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
There is also an inside temperature sensor located to
the left of the ignition button. The automatic climate
control system uses this sensor to receive information,
so if you block or cover it, the system will not function
properly.
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 or frost
from your windshield. Use the oor/defog mode to
clear the windows of fog or moisture and warm
the passengers. Use defrost to remove fog or frost from
the windshield more quickly.
-(Floor/Defog):Press the mode button until the
defog mode appears on the display. This mode directs
the air between the windshield, oor outlets and
side windows. When you select this mode, the system
turns off recirculation and runs the air-conditioning
compressor unless the outside temperature is near or
below freezing. The recirculation mode cannot be
selected while in the oor/defog mode.
1(Defrost):Press this button to direct most of the
air to the windshield, with some air directed to the side
windows. In this mode, the system will automatically
turn off the recirculation and run the air-conditioning
compressor, unless the outside temperature is near or
below freezing. Recirculation cannot be selected while in
the defrost mode. Do not drive the vehicle until all the
windows are clear.
3-45

HOT ENGINE–A/C OFF:This message displays when
the engine coolant becomes hotter than the normal
operating temperature. To avoid added strain on a hot
engine, the air conditioning compressor is automatically
turned off. When the coolant temperature returns to
normal, the A/C operation will automatically resume.
You can continue to drive your vehicle. If this message
continues to appear, have the system repaired by
your GM dealer as soon as possible to avoid
compressor damage.
ICE POSSIBLE:This message appears when the
outside air temperature is cold enough to create icy
road conditions.
LEFT DOOR AJAR:This message will display anytime
the vehicle engine is running, the transmission is not
in PARK (P) and the driver’s door is open or ajar.
A chime will sound when the vehicle’s speed is greater
than 3 mph (4.8 km/h).
LOW BRAKE FLUID:This message will display if the
vehicle is running to inform the driver that the brake
uid level is low. Have the brake system serviced
by your GM dealer as soon as possible. See “Brake
Fluid” underBrakes on page 6-35.LOW COOLANT:This message will appear when there
is a low level of engine coolant. Have the cooling
system serviced by your GM dealer as soon as possible.
SeeEngine Coolant on page 6-22.
LOW FUEL:This message will appear when the fuel
supply is less than 5 gallons (18.9 L) and the display is
turned off. A single chime will also sound when this
message is displayed.
LOW OIL LEVEL:For correct operation of the low oil
sensing system, your vehicle should be on a level
surface. A false LOW OIL LEVEL message may appear
if the vehicle is parked on a grade. The oil level
sensing system does not check for actual oil level if
the engine has been off for a short period of time,
and the oil level is never checked while the engine is
running. If the LOW OIL LEVEL message appears,
and your vehicle has been parked on level ground
with the engine off for at least 30 minutes, the oil level
should be checked by observing the oil dipstick. Prior
to checking the oil level, be sure the engine has been
off for a few minutes and your vehicle is on a level
surface. Then check the dipstick and add oil if
necessary. SeeEngine Oil on page 6-15.
3-70

NO FOB, OFF OR RUN?:When this message displays,
it means that the keyless access transmitter is not
detected inside the vehicle while you are trying to turn
the ignition off. Your vehicle may be near a strong
radio antenna signal causing the keyless access system
to be jammed. The vehicle will remain in ACC until off
or START has been pressed or ve minutes has
expired. If you turn the ignition off and you cannot nd
the keyless access transmitter, you will not be able
to restart the vehicle. The keyless access transmitter
needs to be inside of the vehicle in order for the vehicle
to start. SeeStarting the Engine on page 2-22for
more information.

be applied to start the vehicle. Make sure you are
pressing the brake pedal all the way down.
REDUCED ENGINE POWER:This message informs
you that the vehicle is reducing engine power because
the transmission is being placed in gear under conditions
that may cause damage to the vehicle’s engine,
transmission, or ability to accelerate. Reduced engine
power can affect the vehicle’s ability to accelerate. If this
message is on, but there is no reduction in performance,
proceed to your destination.The performance may be reduced the next time the
vehicle is driven. The vehicle may be driven at a reduced
speed while this message is on, but acceleration and
speed may be reduced. Anytime this message stays on,
the vehicle should be taken to your GM dealer for service
as soon as possible.
RIGHT DOOR AJAR:The passenger’s door is open or
ajar when this message appears. The vehicle must
be running and the transmission not in PARK (P) for this
message to display. A chime will sound if the vehicle’s
speed is greater than 3 mph (5 km/h).
