2006 CADILLAC DTS PROFESSIONAL climate control

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately six seconds.
When the ignition is turned to OFF, the wiper-activated
headlamps will immediately turn off. The wiper-activated
headlamps will also turn off if the windshield wipers
are turned off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles rst sold
in Canada.
The DRL system will make the turn signal lamps come
on when the following conditions are met:
It is still daylight and the ignition is on.
The exterior lamp control is in the off position.
The transaxle is not in PARK (P) (United
States only).
The light sensor is covered or not detecting light.
See “Sensors” underDual Climate Control System
on page 3-44.
When DRL are on, no other exterior lamps such as the
parking lamps, taillamps, etc. will be on when the
DRL are being used. Your instrument panel will not be
lit up either.
When automatic lighting is on and it is dark enough
outside, the turn signal lamps will turn off and normal
low-beam headlamp operation will occur.
When automatic lighting is on and it is bright enough
outside, the regular lamps will go off, and the DRL
will take over. If you start your vehicle in a dark
garage, the automatic headlamp system will come on
immediately. Once you leave the garage, it will take
approximately one minute for the automatic headlamp
system to change to DRL if there is light outside. During
that delay, your instrument panel cluster may not be
as bright as usual. Make sure your instrument
panel brightness knob is in the full bright position.
SeeInstrument Panel Brightness on page 3-36.
Turning on automatic lighting or the headlamps will
deactivate the DRL. If the parking lamps or the
fog lamps were turned on instead, the DRL will still
deactivate.

Reading Lamps
The reading lamps are located on the overhead console
on the headliner and in the rear door opening. These
lamps come on automatically when any door is opened
and it is dark outside.
For manual operation, press the button to turn them on.
Press it again to turn them off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle
at a higher revolutions per minute (rpm) setting
than normal to make sure the battery charges. High
electrical loads may occur when several of the following
are on: headlamps, high beams, fog lamps, rear
window defogger, the climate control fan at high speeds,
heated seats and engine cooling fans.If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass, the heated seats may not get as warm
as they usually do and the climate control fan may cut
back to a lower speed. For more battery saving
information, see “Battery Saver Active Message” under
DIC Warnings and Messages on page 3-76.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, or the garage door opener. When the
ignition is turned off, the power to these features will
automatically turn off after 10 minutes (three minutes if
a new car has 15 miles (24 km) or less). Power will
be restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy lamp switch
is turned on.

Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle. To avoid window fogging
on rainy and humid days at temperatures above
freezing, run the air conditioning compressor. Also, it is
best to avoid the use of recirculation mode except
when maximum air-conditioning performance is needed
for a short amount of time to avoid exterior odors
and fogging.

Automatic Operation
AUTO9(Automatic Fan):When this position is
selected on the fan control, the system will adjust the fan
speed. If the OnStar
®system is activated when this
position is selected, the climate control fan speed
will lower.
AUTO (Automatic Mode):
1. Turn the fan control to the AUTO position.
2. Turn the mode control to the AUTO position.
3. Adjust the temperature to a comfortable setting
between 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. 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 to warm
the interior will depend on the outside temperature
and temperature of the vehicle.
4. Wait 20 to 30 minutes for the system to stabilize in
order for the system to regulate automatically. Then
adjust the temperature as necessary to nd your
comfort setting.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.
After your vehicle is started, the display will show the
interior temperature settings and the outside
temperature.
If the AUTO position is selected on the fan or mode
control, the system will automatically control the
air conditioning compressor. The A/C compressor will
run automatically even at cool outside temperatures
in order to dehumidify the air. The A/C indicator light
will be lit when the system is operating automatically,
even at near freezing outside temperatures. Press
the A/C button on the fan control to turn off the A/C.
For improved window clearing performance in defog
or defrost modes, the A/C compressor will run
automatically in damp cool conditions.
3-45

h(AUTO RECIRCULATION):If the AUTO position
is selected on either the fan or mode control, the
system will automatically control the air inlet to supply
fresh outside air or recirculate the interior air to cool
the car faster. The indicator light on the recirculation
button will light whenever the system switches to
recirculation. You may force outside air by pressing the
button when the light is lit. The next time AUTO fan
or mode is selected, the air inlet will reset back to
AUTO operation.
Manual Operation
9(Fan):Turn the left knob either to the left or right to
adjust the fan speed. Turning this control completely
counterclockwise will turn on the automatic fan
operation. Turning this control to the “O” position will
turn the climate control system off. If the airow seems
low when the fan speed is at the highest setting, the
passenger compartment air lter may need to be
replaced. SeePassenger Compartment Air Filter on
page 3-53.
9(Off):Turn the left control to this position to turn
the entire climate control system off.
To change the current mode, select one of the following
positions using the right control:
AUTO:Turn the control to this position to turn on the
automatic delivery mode operation.
F(Vent):Turn the control to this mode to direct air to
the instrument panel outlets.
*(Bi-Level):Turn the control to this mode to direct
approximately half of the air to the instrument panel
outlets and 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.
7(Floor):Turn the control to this mode to direct most
of the air to the oor outlets with some air directed to
the side window outlets and the windshield.
The mode control can also be used to select the
oor/defog mode. Information on defogging and
defrosting can be found later in this section.
3-46

?(Recirculation):Press this button to keep 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.
Press this button to turn the recirculation mode on or off.
When the button is pressed, an indicator light will
come on.
«ª(Driver’s Temperature Controls):Press these
buttons next to the fan control to manually increase
or decrease the temperature inside your vehicle.
«ª(Passenger’s Temperature Controls):Press
these buttons next to the mode control to manually
increase or decrease the temperature for the front
passenger. If the passenger’s climate control system
is off, pressing one of these buttons will turn it on.
PASS (Passenger’s Climate Control):Press
this button to turn the passenger’s climate control
systems on or off. The temperature selected by the
front passenger will also control the rear system
air temperature unless the rear seat passengers select
their own comfort setting.If the PASS button is pressed to turn the Passenger
temperature setting off, the driver’s temperature
knob will control the temperature for the entire vehicle.
AUX:Press this button to turn the rear climate
control fan on for automatic operation. After the AUX
button is pressed, the indicator light will come on.
Press the button again to turn the auxiliary fan off.
#(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.
The air-conditioning system removes moisture from
the air, so you may notice a small amount of water
dripping underneath your vehicle while idling or after
turning off the engine. This is normal.
3-47

In order to prevent false temperature readings at
startup, the displayed temperature will not change until
the following occurs:
Vehicle speed is above 10 mph (16 kmh) for
5 minutes.
Vehicle speed is above 32 mph (51 kmh) for
2 and a half minutes.
The climate control system uses the information from
these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the air
delivery mode. The system may also supply cooler
air to the side of the vehicle facing the sun. The
recirculation mode will also be used as needed to
maintain cool outlet temperatures.
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 to remove fog or
frost from the windshield more quickly.
W(Floor/Defog):Turning the control to this mode
directs approximately half of the air to the oor outlets
and the remaining air is directed to the side window
outlets and to the windshield. 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.
0(Defrost):Turning the control to this mode directs
most of the air to the windshield and the side window
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.
For professional vehicles, air will be allowed to ow
through the rear outlets. For quicker defrost, press the
AUX button on the front climate control system so
that the light is not lit.
