2006 CADILLAC STS headlamp

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. SeeHeadlamps on page 3-31
for 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.
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 3-71for 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.
3-35

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 3-39.
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.
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.
3-36

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 front 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 you turn on the
high-beam headlamps, the fog lamps will also turn off.
They’ll 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.
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.
3-37

With Twilight Sentinel®you will see the following
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 approximately 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 control is in full bright
position. SeeInstrument Panel Brightness on page 3-39
for 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/ACC. Then start the vehicle. The lamps
will stay off until you release the parking brake.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, your lamps
will remain on until:
The exterior lamp switch is moved from off to the
parking lamp position, or
a delay time that you select has elapsed.
SeeVehicle Personalization on page 2-53to select the
delay time that you want. You can also select no
delay time.
If you turn off the ignition 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, you should turn on the regular
headlamp system when you need it.
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.

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 3-39for additional information. Base Level Shown,

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. Press it again to turn the lamp 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 3-79.
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 (three minutes if
a new car has 15 miles (24 km) or less). Power will
be restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy lamp switch
is turned on.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
If equipped, the Head-Up Display (HUD) allows you to
see some of the driver information that appears on your
instrument panel cluster on the windshield.
3-40

If equipped, this light tells
you if there could be a
problem with your engine
oil pressure.
This light will come on briey when you start your
engine. That is a check to be sure the light works. If it
does not come on, be sure to have it xed so it will
be there to warn you if something goes wrong.
When the light comes on and stays on, it means that oil
is not owing through your engine properly. You
could be low on oil and you might have some other
system problem.

Fuel Gage
The fuel gage shows
approximately how much
fuel is in the tank. It
works only when the
engine is on.
If the fuel supply gets low, the Fuel Level Low message
will appear on the DIC and a single chime will sound. See
DIC Warnings and Messages on page 3-79for more
information.
Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and
do not indicate that anything is wrong with the fuel gage:
At the gas station the gas pump shuts off before
the gage reads full.
The gage may change when you turn, stop quickly
or accelerate quickly.
It takes a little more or less fuel to ll the tank than
the gage indicated. For example, the gage may have
indicated that the tank was half full, but it actually
took a little more or less than half the tank’s capacity
to ll the tank.
