headlamp CADILLAC DTS 2008 1.G User Guide

9(Off):To stop the wipers, move the band to off.
Clear ice and snow from the wiper blades before using
them. If they are frozen to the windshield, carefully
loosen or thaw them. If the blades become worn
or damaged, replace with new blades or blade inserts.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools.
Clear away snow or ice to prevent an overload.
Your vehicle has wiper-activated headlamps. After the
windshield wipers have completed eight wipe cycles
within four minutes, the headlamps automatically
turn on. SeeWiper Activated Headlamps on page 3-35
for more information.
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 3-35for 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
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. SeeHighbeam On Light on
page 3-69.
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 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 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.
3-33

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/
retailer 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 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. 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 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 PARK (P)
(United States only).
The light sensor is covered or not detecting light.
See “Sensors” underDual Climate Control System
on page 3-42.
3-35

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.
When automatic lighting is on and it is bright enough
outside, the regular lamps go off, and the DRL takes over.
If the vehicle is started in a dark garage, the automatic
headlamp system comes 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, the instrument panel
cluster may not be as bright as usual. Make sure the
instrument panel brightness knob is in the full bright
position. SeeInstrument Panel Brightness on page 3-37.
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.
To idle the vehicle with the DRL off at night, turn off
automatic lighting and shift the transmission into
PARK (P). Placing the vehicle in PARK (P) disables the
DRL. The DRL will stay off until the vehicle is shifted
out of PARK (P).To drive the vehicle with the DRL off, turn off automatic
lighting and manually turn on the parking lamps or
fog lamps, if the vehicle has them.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Fog Lamps
Use the fog lamps for better vision in foggy or misty
conditions.
-(Fog Lamps):The fog lamps button is located on
the exterior lamps control. The exterior lamps control
is located on the instrument panel to the left of the
steering column.
The ignition must be on for the fog lamps to work.
Press the exterior lamps button to turn the fog lamps
on or off. A light will come on in the instrument
panel cluster when the fog lamps are in use.
When the headlamps are changed to high-beam,
the fog lamps will turn off. The fog lamps come back
on again when the high-beam headlamps are turned off.
Some localities have laws that require the headlamps
to be on along with the fog lamps.
3-36

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 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 you need to
leave the lamps 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.
3-37

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
If your vehicle has 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 oor areas. They dim with the instrument panel
cluster lights, before going out completely.
Footwell lighting brightness can be adjusted with the
instrument panel brightness control located below
the exterior lamps control. SeeInstrument Panel
Brightness on page 3-37. The footwell lights will turn off
before the instrument panel lights are at their lowest
level of brightness.
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.
3-38

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 3-75.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a voltage display on the Driver Information
Center (DIC), you may see the voltage move up
or down. This is normal. If there is a problem, an
alert will be displayed.The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not be
spinning fast enough at idle to produce all the power
that is needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable
to the driver. If so, a Driver Information Center (DIC)
message might be displayed, such as Battery Saver
Active or Service Battery Charging System. If this
message is displayed, it is recommended that the
driver reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 3-75.

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. Power will
be restored for an additional 10 minutes if any door or
trunk is opened, or the courtesy lamp switch is
turned on.
Battery Run-Down Protection
This vehicle has a feature to help prevent the battery
from being drained, if the interior courtesy lamps,
reading/map lamps, visor vanity lamps or trunk lamp are
accidentally left on. If any of these lamps are left on,
they will automatically turn off after 10 minutes, if
the ignition is off. The lamps will not come back on
again until one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then
on again.
The headlamps will timeout after 10 minutes, if they are
manually turned on before the ignition is off.
Accessory Power Outlet(s)
The accessory power outlets can be used to plug in
electrical equipment such as a cellular telephone,
CB radio, etc.
If your vehicle has a center console, the power outlet is
located inside the lower storage area. There are
outlets also on the right front lower part of the driver’s
seat and under the climate control system next to
the ashtray. SeeCenter Console Storage on page 2-59.
There are two accessory power outlets in the rear
seat area located on the door armrests next to the
ashtrays.
There may be a small cap that must be removed to
access the accessory power outlet. When not using the
outlet be sure to cover it with the protective cap.
The accessory power outlet can be used at any time.
Notice:Leaving electrical equipment plugged in for
an extended period of time while the vehicle is off
will drain the battery. Power is always supplied
to the outlets. Always unplug electrical equipment
when not in use and do not plug in equipment
that exceeds the maximum 20 ampere rating.
