IntelliBeam®Intelligent High-Beam
Headlamp Control System
For vehicles with this feature, be sure to read this entire
section before using it.
IntelliBeam is an enhancement to the vehicle's
headlamp system. Using a digital light sensor on the
rearview mirror, this system turns the vehicle's
high-beam headlamps on and off according to
surrounding traffic conditions.
The IntelliBeam system turns the 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
turns on to indicate the system is on. Once the system
has been turned on, it remains on each time the vehicle
is started, but 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 appears
on the instrument panel cluster when the high-beams
are on. See Highbeam On Light on page 4‑58.
Driving with IntelliBeam
IntelliBeam only activates the high-beams when driving
over 20 mph (32 km/h).
The high-beam headlamps remain on, under the
automatic control of IntelliBeam, until any of the
following situations occur:
.The system detects an approaching vehicle's
headlamps.
.The system detects a preceding vehicle's
taillamps.
.The outside light is bright enough that high-beam
headlamps are not required.
.The vehicle's speed drops below 15 mph
(24 km/h).
.The headlamp stalk is moved forward to the
high-beam position or the flash-to-pass feature is
used. SeeHeadlamp High/Low-Beam Changer
on
page 4‑6and Flash-to-Passon page 4‑10.
When either of these conditions occur, the
IntelliBeam feature is disabled and the IntelliBeam
light in the mirror turns off until the high-beam stalk
is returned to the neutral position.
.If IntelliBeam was using low-beams prior to this
action, the IntelliBeam feature is temporarily
disabled until the stalk is returned to the neutral
position.

.The exterior lamp control is turned to any setting
except AUTO.
When this occurs, IntelliBeam is disabled until the
control is turned back to the AUTO position.
.The IntelliBeam system is turned off at the inside
rearview mirror.
IntelliBeam might not turn off the high-beams if the
system cannot detect other vehicle's lamps because of
any of the following:
.The other vehicle's lamp(s) are missing, damaged,
obstructed from view, or otherwise undetected.
.The other vehicle's lamp(s) are covered with dirt,
snow, and/or road spray.
.The other vehicle's lamp(s) cannot be detected
due to dense exhaust, smoke, fog, snow, road
spray, mist, or other airborne obstructions.
.Your vehicle's windshield is dirty, cracked,
or obstructed by something that blocks the view of
the IntelliBeam light sensor.
.Your vehicle's windshield is covered with ice, dirt,
haze, or other obstructions.
.Your vehicle is loaded such that the front end of
the vehicle points upward, causing the IntelliBeam
sensor to aim high and not detect headlamps and
taillamps.
.You are driving on winding or hilly roads. You might need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.
Disabling and Resetting IntelliBeam at the
Rearview Mirror
IntelliBeam can be disabled by using the controls on the
inside rearview mirror.
AUTO
3(On/Off):
Press this button on the inside
rearview mirror to disable the system. The IntelliBeam
indicator turns off and does not come back on until the
IntelliBeam button is pressed again.
When IntelliBeam has turned on the high-beams, pull or
push the high-beam stalk. This will disable IntelliBeam.
The IntelliBeam indicator on the mirror turns off. To turn
IntelliBeam back on, press the IntelliBeam button on the
mirror.
A different sensitivity setting is available for dealer
diagnostics. This is done by pushing and holding this
button for 20 seconds until the IntelliBeam indicator light
flashes three times. If you accidentally activate this, the
vehicle' s setting automatically is reset when the ignition
is turned off and then on again.

Cleaning the IntelliBeam Light Sensor
The light sensor is located
on the inside of the
vehicle in front of the
inside rearview mirror.
Clean the light sensor window, periodically, using glass
cleaner on a soft cloth. Gently wipe the sensor window.
Do not spray glass cleaner directly on the surface of the
sensor window.
Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers are turned on and have
completed eight wipe cycles within four minutes.
When the ignition is turned to LOCK/OFF, the
wiper-activated headlamps immediately turn off. The
wiper-activated headlamps 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.
Fully functional daytime running lamps are required on
all vehicles first sold in Canada.
The DRL system makes 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 transmission is not in P (Park) (United
States only).
.The light sensor is covered or not detecting light.
See “Sensors” underDual Climate Control System
on page 4‑34.
When DRL are on, no other exterior lamps such as the
parking lamps, taillamps, etc. will be on when the DRL
are being used. The instrument panel will not be lit up
either.
When automatic lighting is on and it is dark enough
outside, the turn signal lamps turn off and normal
low-beam headlamp operation occurs.

Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off about 10 minutes after the ignition is
turned to LOCK/OFF and a door has been opened. This
protects against draining the battery if the headlamps or
parking lamps are accidentally left on. If the lamps need
to be left on for more than 10 minutes, use the exterior
lamp control to turn the lamps back on after the ignition
is turned to LOCK/OFF and any door is opened.
Instrument Panel Brightness
D(Instrument Panel Brightness): This feature
controls the brightness of the instrument panel and
footwell lights, if equipped.
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 or counterclockwise to
brighten or dim the lights.
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 for the door switches and the exterior lamp
control when a door is opened or if the remote keyless
entry transmitter unlock button is pressed. If activated
due to the transmitter, the lighting remains 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 ON/
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.
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.
Footwell Lamps
For vehicles with footwell lamps, they are located under
the instrument panel and at the rear of the front seats.
These lamps provide soft light to the front and rear floor
areas. They dim with the instrument panel cluster lights.Footwell lighting brightness can be adjusted with the
instrument panel brightness control located below the
exterior lamps control. See
Instrument Panel Brightness
on page 4‑30. The footwell lights will turn off before the
instrument panel lights are at their lowest level of
brightness.
Battery Load Management
This feature monitors the vehicle's electrical load and
determines 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 4‑65.

Automatic Operation
AUTO9(Automatic Fan): When this position is
selected on the fan control, the system adjusts the fan
speed. To use automatic operation:
1. Turn the fan control to the AUTO position.
2. Turn the air delivery mode to the AUTO position.
3. Adjust the temperature to a comfortable setting between 21°C (68°F) and 26°C (78°F).
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 the vehicle until warmer air is available. The
system starts out blowing air at the floor 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 depends
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 find
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 the vehicle is started, the display shows the
interior temperature settings and the outside
temperature.

Black plate (39,1)Cadillac DTS Owner Manual - 2011
The heated outside rearview mirrors will turn on to help
clear fog or frost from the surface of the mirror when the
rear window defogger is on.
Notice:Do not use a razor blade or sharp object
to clear the inside rear window. Do not adhere
anything to the defogger grid lines in the rear glass.
These actions may damage the rear defogger.
Repairs would not be covered by your warranty.
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 the
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.
4-39

Black plate (40,1)Cadillac DTS Owner Manual - 2011
In order to prevent false temperature readings at
startup, the displayed temperature will not change until
the following occurs:
.Vehicle speed is above 16 km/h (10 mph) for
5 minutes.
.Vehicle speed is above 51 km/h (32 mph) 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.
Outlet Adjustment
For the front outlets, use the thumbwheel located below
each outlet to change the direction of the airflow. Use
the thumbwheel located next to the outlets to shut the
airflow or to open the outlets and re-direct the air.
For the rear outlets, slide the lever left or right and up or
down to change the direction of the airflow.
Operation Tips
.Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may block
the flow of air into your vehicle.
.Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
.Keep the path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.
Rear Climate Control System
For vehicles with a rear climate control system, the rear
seat passengers can adjust the direction of the airflow,
fan speed and temperature for the rear seating area.
This system also works with the main climate control
system in the vehicle.
