2007 CADILLAC XLR air conditioning

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 asthe 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). See
DIC Controls and Displays on page 204for
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.

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.
((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.
181

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.
If the outside temperature goes up, the display
temperature will not change until:
The vehicle’s speed is above 15 mph
(24 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.
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. Do not
drive the vehicle until all the windows are clear.

SERVICE A/C
This message displays when the electronic
sensors that control the air conditioning and
heating systems are no longer working. Have the
climate control system serviced by your dealer
if you notice a drop in heating and air conditioning
efficiency.
SERVICE ABS (Anti-lock Brake System)
If this message displays when you are driving,
stop as soon as possible and turn the ignition off.
Then start the engine again to reset the system.
If the message stays on, or comes back on again
while you are driving, your vehicle is in need of
service. See your dealer.
If the SERVICE ABS message is being displayed,
the Traction Control System (TCS) and
StabiliTrak
®System will also be disabled. The
Driver Information Center will scroll three
messages: SERVICE ABS, SERVICE TRACTION
SYS, and SERVICE STABILITRAK, and the
anti-lock brake system and traction control warning
lights on the instrument panel cluster will beilluminated. SeeAnti-Lock Brake System Warning
Light on page 193andTraction Control System
(TCS) Warning Light on page 194. The driver can
acknowledge these messages by pressing the
RESET button three times. When the service
message is displayed, the computer controlled
systems will not assist the driver and you should
have the system repaired by your dealer as
soon as possible. Adjust your driving accordingly.
SERVICE AFS (Adaptive Forward
Lighting System) LAMPS
This message displays when the Adaptive
Forward Lighting System (AFS) is disabled and
needs service. See your dealer. SeeAdaptive
Forward Lighting System on page 167for more
information.
SERVICE ELECT (Electrical) SYSTEM
This message displays if an electrical problem has
occurred within the Powertrain Control Module
(PCM). Have your vehicle serviced by your dealer.

(F) Service Description:These characters
represent the load range and speed rating of the
tire. The load index represents the load carry
capacity a tire is certied to carry. The load index
can range from 1 to 279. The speed rating is
the maximum speed a tire is certied to carry a
load. Speed ratings range from A to Z.
Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the
tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic
transmission/transaxle, power steering, power
brakes, power windows, power seats, and

to its width.
Belt:A rubber coated layer of cords that is located
between the plies and the tread. Cords may be
made from steel or other reinforcing materials.
Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.
Cold Tire Pressure:The amount of air pressure
in a tire, measured in pounds per square inch
(psi) or kilopascals (kPa) before a tire has built up
heat from driving. SeeInation - Tire Pressure
