2005 CADILLAC CTS air condition

The passenger sensing system will turn off the right
front passenger’s frontal airbag under certain conditions.
The driver’s airbag and the side airbags are not part
of the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat. The
sensors are designed to detect the presence of a
properly-seated occupant and determine if the
passenger’s frontal airbag should be enabled
(may inate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun visor
says, “Never put a rear-facing child seat in the
front.” This is because the risk to the rear-facing child is
so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal
airbag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one can
guarantee that an airbag will not deploy under
some unusual circumstance, even though it is
turned off. General Motors recommends that
rear-facing child restraints be secured in the
rear seat, even if the airbag is off.
The passenger sensing system is designed to turn off
the right front passenger’s frontal airbag if:
the right front passenger seat is unoccupied
the system determines that an infant is present in a
rear-facing infant seat
the system determines that a small child is present
in a forward-facing child restraint

Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
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).Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the warmest
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). If you have the Base
audio system, seeDIC Main Menu on page 3-62.Ifyou
have the Navigation system, see “Setup Menu” in the
Index of the CTS Navigation System Owner Manual.
3-27

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
yNz(Mode):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.
The outboard air outlets will always receive
airow regardless of the mode selected. SeeOutlet
Adjustment on page 3-31to change this airow from the
outboard outlets.
To change the current mode, select one of the following:
Y(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.
[(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 defog
mode. Information on defogging and defrosting can
be found later in this section.
yAz(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 3-32
andScheduled Maintenance on page 6-4.
h(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.
The air-conditioning compressor also comes on.
Recirculation is not available in the defrost mode and will
automatically turn off after 10 minutes when defog is
selected.
3-28

Using recirculation for long periods of time may cause the
air inside your vehicle to become too dry or stuffy. To
prevent this from happening, after the air in your vehicle
has cooled, turn the recirculation mode off.
QPWRR(Power/Driver’s Temperature):Press the
PWR button located on the driver’s 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 increase or decrease the temperature
inside your vehicle.
QPWRR(Power/Passenger’s Temperature):Press
the PWR button located on the passenger’s side of
the climate control panel to allow the passenger’s
climate control setting to be different than the driver’s.
Press the up or down arrow on the switch to increase or
decrease the temperature for the front passenger.
A/C OFF (Air Conditioning):Press this button to
manually turn off the air conditioning compressor. Press
AUTO to return to automatic operation or press the
A/C OFF button again.
Sensors
There is a solar sensor located on the instrument panel,
near the windshield.
3-29

There is also an interior
temperature sensor
located to the right of the
steering wheel on the
instrument panel.
These sensors monitor the solar radiation and the air
inside your vehicle, then use 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 sensors or the automatic climate
control system will not work 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 from
your windshield. Use the defog mode to clear the
windows of fog or moisture and warm the passengers.
Use the defrost mode to remove fog or frost from
the windshield more quickly.
yNz(Mode):Press this button until defog appears
on the display.
-(Defog):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 at or below freezing. The
recirculation mode is cancelled when you enter defog
mode. If you select recirculation while in defog mode, it
will be cancelled after 10 minutes.
If you have fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. SeeOutlet Adjustment on page 3-31
for more information.
3-30

0(Defrost):Pressing defrost direts most of the
air to the windshield, with some air directed to the side
windows. 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.
This mode may also cause the fan speed and air
temperature to increase.
If you have fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. SeeOutlet Adjustment on page 3-31
for more information. 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 Window Defogger):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 about 10 minutes
after the button is pressed. Or, if the vehicle’s speed
is above 30 mph (48 km/h), the rear defogger will stay
on continuously. If turned on again, the defogger
will only run for about 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 window defogger button is on.
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 knobs located in the center of each outlet to
change the direction of the airow. Use the thumbwheels
to open or close the outlets.
j(Side Window Defog):Turn the thumbwheel to this
symbol to use the side window defog setting. The air
coming through the outlets will be directed toward
the side windows to clear fog.

This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible
If the light stops ashing and remains on steady, see “If
the Light Is On Steady” following.If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart
the engine. If the light remains on steady, see “If
the Light Is On Steady” following. If the light is still
ashing, follow the previous steps, and see your dealer
for service as soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. SeeFilling the Tank on page 5-8. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
