2006 CADILLAC DTS headlamp

Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor is
mounted on the interior side of the windshield behind the
rearview mirror. It is used to automatically operate the
wipers by monitoring the amount of moisture build-up
on the windshield. Wipes occur as needed to clear
the windshield depending on driving conditions and the
sensitivity setting. In light rain or snow, fewer wipes
will occur. In heavy rain or snow, wipes will occur more
frequently. The Rainsense™ II wipers operate in a
delay mode as well as a continuous low or high speed
as needed. If the system is left on for long periods
of time, occasional wipes may occur without any
moisture on the windshield. This is normal and indicates
that the Rainsense™ II system is activated.
The Rainsense™ II system can be activated by turning
the wiper band to one of the ve sensitivity levels
indicated on the wiper stalk. The position closest to off is
the lowest sensitivity setting, level one. This allows more
rain or snow to collect on the windshield between wipes.Turning the wiper band away from you to higher
sensitivity levels increases the sensitivity of the system
and frequency of wipes. The highest sensitivity setting,
level ve is closest to low. A single wipe will occur each
time you turn the wiper stalk to a higher sensitivity level
to indicate that the sensitivity level has been increased.
Notice:Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.
The mist and wash cycles operate as normal and
are not affected by the Rainsense™ II function. The
Rainsense™ II system can be overridden at any time by
manually turning the wiper band to low or high speed.
When Rainsense™ II is active, the headlamps will
turn on automatically. The headlamps will turn off
again once the wipers turn off if it is light enough
outside. If it is dark, they will remain on. SeeWiper
Activated Headlamps on page 3-34for more information.
Notice:Do not place stickers or other items
on the exterior glass surface directly in front of
the moisture sensor. Doing this could cause
the moisture sensor to malfunction.

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.
3-31

Driving with IntelliBeam™
IntelliBeam™ will only activate your high-beams when
driving over 20 mph (32 km/h).
The high-beam headlamps will 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 ash-to-pass feature is
used. SeeHeadlamp High/Low-Beam Changer
on page 3-9andFlash-to-Pass on page 3-13.
When either of these conditions occur, the
IntelliBeam™ feature will be disabled and the
IntelliBeam™ light in the mirror will turn 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 will be 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™ will be disabled
until the control is turned back to the AUTO position.
The IntelliBeam™ system is turned off at the inside
rearview mirror.
IntelliBeam™ may not turn off the high-beams if the
system cannot detect other vehicle’s lamps because of
any of the following:
The others 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.
3-32

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 may 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):To disable the system, press this
button on the inside rearview mirror. The IntelliBeam™
indicator will turn off and the will not come back on until
the IntelliBeam™ button is pressed again.
(Stalk Disable):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 will turn off. To re-enable IntelliBeam™,
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 ashes three times. If you accidentally activate this,
the vehicle’s setting will automatically be reset each
time the ignition is turned off and then on again.

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.
3-34

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.
