2006 CADILLAC DTS PROFESSIONAL sensor

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.

Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel lights.
The button for this control is located below the exterior
lamps control.
Push the button in and release to extend the button.
Turn the button clockwise for brightness of the
instrument panel lights and counter clockwise to turn
the brightness down.
Courtesy Lamps
The courtesy lamps are located on the headliner above
the rear seat. These lamps come on by turning the
instrument panel brightness knob fully clockwise or when
any door is opened and it is dark outside. Puddle
lamps are located on the bottom of the front and rear
door trim.
Professional vehicles have an additional dome lamp and
also opera lamps.
Entry Lighting
This feature turns on the courtesy lamps and the
backlighting to the door switches and to the exterior
lamp control when a door is opened or if you press the
remote keyless entry transmitter unlock button. If
activated due to the transmitter, the lighting will remain
active for about 40 seconds. Since the entry lighting
system uses the light sensor, it must be dark outside in
order for the courtesy lamps to turn on. The courtesy
lamps turn off approximately 25 seconds after the
last door is closed. They will dim to off if the ignition key
is turned to RUN, or immediately deactivate if the
power locks are activated.
Parade Dimming
This feature prohibits dimming of the digital displays and
backlighting during daylight hours when the key is in
the ignition and the headlamps are on. This feature is
fully automatic. When the light sensor reads darkness
outside and the parking lamps are active, the digital
displays can be adjusted by turning the instrument panel
brightness knob counterclockwise to dim and clockwise
to brighten lighting.

Ultrasonic Front and Rear Parking
Assist (UFRPA)
If your vehicle is equipped, the Ultrasonic Front and
Rear Parking Assist (UFRPA) system is designed
to help you park. It operates only at speeds less than
5 mph (8km/h). UFRPA helps make parking easier and
helps you avoid colliding with objects such as parked
vehicles. The UFRPA system detects objects that
are close to the vehicle which are at least 10 inches
(25.4 cm) off the ground and below hood or trunk level.
The system detects objects up to 4 feet (1.2 m) in
front of the vehicle and up to 8 feet (2.5 m) behind your
vehicle. UFRPA determines how close these objects
are from your bumpers within this area. Four ultrasonic
sensors on the front and rear bumpers are used to
detect the distance to the object.
{CAUTION:
Even with the Ultrasonic Front and Rear Park
Assist system, the driver must check carefully
before backing up or moving forward while
parking. The system does not operate above
speeds of 5 mph (8 km/h). The system does
not detect objects that are more than 4 feet
(1.2 meters) in front of the vehicle and more
than 8 feet (2.5 meters) behind the vehicle.
This detection distance limit may be reduced
during warm weather or high humidity. Also,
the system does not detect objects that are
below your bumper, underneath your vehicle,
or some objects very close to the vehicle.
The system is not designed to detect children,
pedestrians, bicyclists, or pets.
So, unless you check carefully behind and in
front of your vehicle while you are parking
they could be injured or killed.
Whether or not you are using front and rear
park assist, always check carefully in front and
behind your vehicle before moving forward or
backing up and then watch closely as you do.
3-38

When you are backing the vehicle and objects are
detected at the same time near both the front and rear
bumpers, both color-coded light displays will notify
you of objects close to each bumper. If there are objects
detected near both bumpers, the beeps will only be
sounded to notify that objects are close to the rear
bumper. However, if while you are backing and an object
comes within 1 ft (0.3 m) of the front bumper, and at
the same time there is another object further than
1 ft (0.3 m) from the rear bumper, then the beeps will
only be sounded to notify you of the closer object that is
near the front bumper.
When the System Does Not Seem to
Work Properly
If the UFRPA system will not activate due to a temporary
condition, the message PARKING ASSIST OFF will
be displayed on the DIC and a red light will be shown on
the rear UFRPA display when the shift lever is moved
into REVERSE (R). This occurs under the following
conditions:
The driver disables the system. SeeDIC Controls
and Displays on page 3-72.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your trunk during
your last drive when you turned off the vehicle. If the
attached objects are removed from your vehicle
before the start of your next drive, the system will
return to normal operation unless an object is
detected when the vehicle is shifted out of park.
If this occurs, you will have to wait until the vehicle
is driven forward above 15 mph (25 km/h) before
UFRPA will return to normal operation.
A bicycle or an object is attached to the front
bumper during your last drive when you turned off
the vehicle. If the attached objects are removed
from your vehicle before the start of your next drive,
the system will return to normal unless an object
is detected when the vehicle is shifted out of park.
If this occurs, UFRPA will return to normal
operation when the vehicle is driven forward
above 15 mph (25 km/h).
The ultrasonic sensors are not kept clean.
So be sure to keep your vehicle’s front and rear
bumpers free of mud, dirt, snow, ice and slush.
For cleaning instructions, seeWashing Your Vehicle
on page 5-86. If after cleaning the front and rear
bumpers and driving forward at a speed of
at least 15 mph (25 km/h), the DIC displays the
PARKING ASSIST OFF message, see your dealer.

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.

Sensors
The solar sensor, located in the defrost grille, middle of
the instrument panel, monitors the solar radiation.
Do not cover the solar sensor or the system will not
work properly.There is also an interior temperature sensor located
next to the steering wheel that measures the
temperature of the air inside your vehicle.
There is also an exterior temperature sensor located
behind the front grille. This sensor reads the outside air
temperature and helps maintain the temperature inside
the vehicle. Any cover on the front of the vehicle could
cause a false reading in the displayed temperature.
3-48

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.

Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to RUN or
START, a chime will sound for several seconds to
remind the front passenger to buckle their safety belt.
This would only occur if the passenger airbag is enabled.
SeePassenger Sensing System on page 1-65for more
information. The passenger safety belt light will also
come on and stay on for several seconds, then it will ash
for several more.
This chime and light will be
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither the
chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the airbag sensors, the
airbag modules, the wiring and the diagnostic module.
For more information on the airbag system, see
Airbag System on page 1-54.
This light will come on
when you start your
vehicle, and it will ash for
a few seconds. Then the
light should go out. This
means the system is ready.
If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your airbag
system may not work properly. Have your vehicle
serviced right away.
