2007 CADILLAC STS headlamp

The high-beam headlamps are manually
turned on or you use the ash-to-pass feature.
SeeHeadlamp High/Low-Beam Changer on
page 183andFlash-to-Pass on page 188.
When either of these conditions occur,
the IntelliBeam™ feature is temporarily
disabled until the high-beam stalk is returned
to the neutral position. If either of these
conditions occur and IntelliBeam™ already
has the high-beam headlamps on, the
IntelliBeam™ feature is disabled and the
IntelliBeam™ light in the mirror turns off.
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 and the AUTOMATIC LIGHTS
ON message displays on the DIC.
The IntelliBeam™ system is turned off at the
inside rearview mirror.
The vehicle’s speed drops below
15 mph (24 km/h).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.
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 and reset to the
original factory setting by using the controls on the
inside rearview mirror.
AUTO
3(IntelliBeam™ On/Off):To disable the
system, press this button on the inside rearview
mirror. 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 disables
IntelliBeam™ and the IntelliBeam™ indicator
on the rearview mirror turns 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 light ashes
three times. If you accidentally activate this, the
vehicle’s setting automatically resets each time the
ignition is turned off and then on again; otherwise,
refer to the text above for resetting the system.
Cleaning the IntelliBeam™ Light Sensor
The light sensor is
located on the inside of
the vehicle at the back of
the 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 have been in
use for about six seconds. For this feature to work,
automatic lighting must be enabled. See
Headlamps on page 211for additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also
turn off if the windshield wiper control is turned off.
215

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. SeeLights On Reminder on
page 256for additional information.
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 automatic lights are enabled, and
the transmission is not in PARK (P).
When DRL are on, only your front turn signal
lamps will be on. No other exterior lamps will be
on when the DRL are being used. Your instrument
panel will not be lit.When the automatic lights are enabled and it is dark
enough outside, the DRL will turn off and the
low-beam headlamps will turn on. When it is bright
enough outside, the low-beam headlamps will go
off, and the DRL will turn back on. 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 about one minute for the
automatic headlamp system to change to DRL if it
is light outside. During that delay, your instrument
panel cluster may not be as bright as usual. Make
sure your instrument panel brightness lever is in the
full bright position. SeeInstrument Panel Brightness
on page 220.
To operate your vehicle with the DRL off, turn the
exterior lamp control off and then do one of the
following:
Turn the exterior lamp control to the parking
lamp position.
Turn the exterior lamp control to the headlamp
position.
Turn the exterior lamp control from AUTO to
off and back to AUTO.
216

An AUTOMATIC LIGHTS OFF message will
appear on the DIC, showing that automatic lighting
has been disabled.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
Light Sensor
The light sensor for the DRL is located on top of
the instrument panel. If you cover the sensor, it will
read dark, and the exterior lamps may come on
when you do not need them.
Fog Lamps
Use the fog lamps for better vision in foggy or
misty conditions.
The fog lamp controls are located on the turn
signal/multifunction lever.
-(Fog Lamps):The band with this symbol is
used to turn the fog lamps on and off.
The parking lamps must be on for the fog lamps
to work.
To turn the fog lamps on, turn the fog lamp band
on the lever up to the dot and release it. The
band will return to its original position.
To turn the fog lamps off, turn the fog lamp band
up to the dot and release it. The band will
return to its original position, and the fog lamps
will turn off. If the high-beam headlamps are turned
on, the fog lamps will also turn off. They will turn
back on again when you switch back to low-beam
headlamps.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
217

Twilight Sentinel®
Twilight Sentinel®can turn your lamps on and off
for you.
A light sensor on top of the instrument panel
makes the Twilight Sentinel
®work, so be sure it is
not covered.With Twilight Sentinel
®the following will happen:
When it is dark enough outside, the front
turn signal lamps (DRL) will go off, and
the headlamps and parking lamps will come
on. The other lamps that come on with
headlamps will also come on.
When it is bright enough outside, the
headlamps will go off, and the front turn signal
lamps (DRL) will come on, as long as the
exterior lamp switch is in the off position.
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 about one minute for the automatic headlamp
system to change to DRL if it is light outside.
During that delay, the instrument panel cluster
might not be as bright as usual. Make sure
the instrument panel brightness control is in full
bright position. SeeInstrument Panel Brightness
on page 220for more information.
You can idle the vehicle with the lamps off, even
when it is dark outside. First set the parking
brake while the ignition is in OFF/ACCESSORY.
Then start the vehicle. The lamps will stay off until
the parking brake is released.
218

Twilight Sentinel®also provides exterior
illumination as you leave the vehicle. If Twilight
Sentinel
®has turned on the lamps when you turn
off the ignition, the lamps will remain on until:
The exterior lamp switch is moved from off to
the parking lamp position.
A delay time that you select has elapsed.
SeeVehicle Personalization on page 148to select
the delay time that you want. You can also
select no delay time.
If the ignition is turned off with the exterior lamp
switch in the parking lamp or headlamp position,
the Twilight Sentinel
®delay will not occur.
The lamps will turn off as soon as the switch is
turned off.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been
left on, the exterior lamps will turn off about
10 minutes after the ignition is turned 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 is
turned 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.
219

Instrument Panel Brightness
This feature controls the
brightness of the
instrument panel lights.
Press in the center knob on the DIC control panel
until the knob pops out. Then turn the knob
clockwise to brighten the lights or counterclockwise
to dim them. If you turn the knob completely
clockwise, the interior lamps will turn on.
Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior
lamp control when a door is opened or if you
press the remote keyless entry transmitter
unlock button. If activated by the transmitter, the
lighting will remain active for about 25 seconds.
The entry lighting system uses the light sensor; it
must be dark outside in order for the lamps to
turn on. The lamps turn off about 25 seconds after
the last door is closed. They will dim to off if the
ignition is on, or immediately deactivate if the
power locks are activated.
Parade Dimming
This feature prohibits dimming of the instrument
panel displays and backlighting during daylight
hours when the key is in the ignition and the
headlamps are on. This feature operates with the
light sensor and is fully automatic. When the
light sensor reads darkness outside and the
parking lamps are active, the instrument panel
displays can be adjusted by turning the instrument
panel brightness knob. SeeInstrument Panel
Brightness on page 220for additional information.

Reading Lamps
The reading lamps are located on the overhead
console. These lamps come on automatically when
any door is opened.
For manual operation, press the button next to
each lamp to turn it on or off.
If the reading lamps are left on, they automatically
shut off 10 minutes after the ignition has been
turned off.
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.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 and the
fan may cut back to a lower speed. For more
battery saving information, see “Battery Saver
Active Message” underDIC Warnings and
Messages on page 264.
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 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.
