2006 CADILLAC DTS PROFESSIONAL lights

If this symbol does not appear, or disappears briey,
Adaptive Cruise Control will not respond to vehicles you
may see ahead.
{CAUTION:
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not detect
a vehicle ahead. Adaptive Cruise Control may
not have time to slow your vehicle enough to
avoid a collision. Do not use Adaptive Cruise
Control when the radar is blocked by snow,
ice, or dirt. Keep your radar clean. See
“Cleaning the System” later in this section.
Adaptive Cruise Control will automatically slow your
vehicle down when approaching a slower moving
vehicle. It will then adjust your speed to follow the
vehicle in front at the selected follow distance. Your
speed will increase or decrease to follow the vehicle
in front of you but will not exceed the set speed. It may
apply limited braking, if necessary. When braking is
active, your brake lights will come on. Braking may
feel or sound different than if you were applying
the brakes yourself. This is normal.
Stationary or Very Slow-Moving Objects
{CAUTION:
Adaptive Cruise Control may not detect and
react to stationary or slow-moving vehicles or
other objects ahead of you. You could crash
into an object ahead of you. Do not use
Adaptive Cruise Control when approaching
stationary or slow-moving vehicles or other
objects.
{CAUTION:
Adaptive Cruise Control may not detect and
react to stationary or slow-moving vehicles or
other objects ahead of you. Your vehicle may
accelerate toward objects, such as a stopped
vehicle that suddenly appears after the lead
vehicle changes lanes. Your complete attention
is always required while driving and you should
be ready to take action and apply the brakes.

IntelliBeam™ Intelligent High-Beam
Headlamp Control System
If your vehicle has this feature, be sure to read this
entire section before using it.
IntelliBeam™ is an enhancement to your vehicle’s
headlamp system. Using a digital light sensor on your
rearview mirror, this system will turn the vehicle’s
high-beam headlamps on and off according to
surrounding traffic conditions.
The IntelliBeam™ system will turn your high-beam
headlamps on when it is dark enough, there is no other
traffic present, and the IntelliBeam system is enabled.
Turning On and Enabling IntelliBeam™
Press and release the IntelliBeam™ button on the inside
rear view mirror. The IntelliBeam™ indicator on the
mirror will turn on to let you know the system has
been turned on. Once the system has been turned
on, it will remain on each time the vehicle is started.
Additionally, the IntelliBeam system must be enabled.
To enable the IntelliBeam™ system, turn the exterior
lamp control to AUTO, with the turn signal/multifunction
lever in its neutral position. The High-Beam On Light
will appear on the instrument panel cluster when
the high-beams are on. SeeHighbeam On Light on
page 3-70.

To idle your vehicle with the DRL off at night, turn off
automatic lighting and shift the transaxle into PARK (P).
Placing your vehicle in PARK (P) disables the DRL.
The DRL will stay off until you shift out of PARK (P).
To drive your vehicle with the DRL off, turn off automatic
lighting and manually turn on the parking lamps or fog
lamps (if equipped).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps
Use the fog lamps for better vision in foggy or misty
conditions.
-(Fog Lamps):Your vehicle is equipped with fog
lamps. It is located on the exterior lamps control.
The exterior lamps control is located on the instrument
panel to the left of the steering column.
When you press the exterior lamps control, the fog lamp
lights on the instrument panel cluster will come on to
indicate that the front and rear fog lamps and the parking
lamps are on.
Press the button again to turn them off.
If you turn on the high-beam headlamps, the fog lamps
will turn off. They will turn back on again when you
switch to low-beam headlamps.When automatic lighting is on and the fog lamps are
turned on, the fog lamps, headlamps and parking lamps
will remain on.
The ignition must be on for the fog lamps to operate.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Cornering Lamps
The cornering lamps come on when the headlamps or
parking lamps are on and you signal a turn with the
multifunction lever. They provide more light for
cornering.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off approximately
10 minutes after the ignition is turned to OFF. This
protects against draining the battery in case you have
accidentally left the headlamps or parking lamps on.
The battery saver does not work if the headlamps are
turned on after the ignition switch is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn the
lamps back on.

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.

The front display is located on top of the instrument
panel to the right of the driver. The rear display is
located near the rear window and can be seen by
looking over your right shoulder. The rear display has
three color-coded lights. The front display will have
either three or six lights depending on whether
your vehicle is equipped with Adaptive Cruise Control
(ACC). If your vehicle has ACC, it will have three lights
along with the ACC lights. If your vehicle does not
have ACC, it will have six UFRPA lights.The UFRPA lights are used to provide distance and
system information, along with beeps played out either
the front or rear speakers. For objects detected near
the front bumper, high-toned beeps will be played
out the front speakers. For objects detected near the
rear bumper, low-toned beeps will be played out the
rear speakers.
How the System Works
When the vehicle is started, the front display will
briey illuminate to let you know the display is
operating correctly. When the shift lever is moved into
REVERSE (R), the rear display will briey illuminate
to let you know the display is operating correctly.
UFRPA comes on automatically when the shift lever is
moved out of PARK (P). The system does not work
at a forward speed greater than 5 mph (8 km/h), so
the front display indicators are turned off. The system
also does not work at a reverse speed greater than
5 mph (8 km/h). To remind you of this, the red light on
the rear display will ash.
The system can be disabled using the Driver Information
Center (DIC). SeeDIC Controls and Displays on
page 3-72. Front Parking Assist

How the System Works when
Moving Forward
When moving forward, the system detects objects only
near the front bumper.
If an object is detected at a forward speed of less
than 5 mph (8 km/h), or if you are already within a
4 ft (1.2 m) distance to a detected object when
UFRPA rst comes on, the following describes what
will occur according to your distance from an object
located in front of the vehicle:
At distances between 40 inches (1 m) and
4 ft (1.2 m), two amber lights will be lit. If you
have Adaptive Cruise Control, a single amber
light will be lit.
At distances between 23 inches (0.6 m) and
40 inches (1 m), four amber lights will be lit.
If you have Adaptive Cruise Control, two amber
lights will be lit.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all six lights (four amber lights/
two red lights) will be lit. If you have Adaptive Cruise
Control, all three lights (amber/amber/red) will be lit.
At distances less than 12 inches (0.3 m), a chime will
sound for a short time and all six lights (four amber
lights/two red lights) will be lit and ashing. If you
have Adaptive Cruise Control, a chime will sound for
a short time and all three lights (two amber lights/
one red light) will be lit and ashing.
How the System Works when Backing
When backing, UFRPA detects objects close to the
front and rear bumpers. The rst time an object
is detected a single chime will sound. If an object is
detected at a REVERSE (R) speed of less than 5 mph
(8 km/h), or if you are already within an 8 ft (2.5 m)
distance to a detected object when the system
rst comes on, the following describes what will occur
according to your distance from an object located behind
the vehicle:
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will be lit.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be lit.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/amber/red)
will be lit.
At distances less than 12 inches (0.3 m), a chime
will sound for a short time and all three lights
(amber/amber/red) will be lit and ashing.

Warning Lights, Gages,
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention
to your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they are working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Follow this manual’s
advice. Waiting to do repairs can be costly and even
dangerous. So please get to know your warning
lights and gages. They are a big help.
Your vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-71for
more information.
