2006 CADILLAC XLR V headlamp

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 front 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 and
the transmission is not in PARK (P).
When DRL are on, only the front turn signal lamps will
be 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 it is dark enough outside, the front turn signal
lamps will turn off and normal low-beam headlamps
will turn on.When it is bright enough outside, the regular lamps will
go off, and the front turn signal lamps 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 it 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 3-33
for more information.
If it is dark enough outside and the exterior lamp control
is off, a HEADLAMPS SUGGESTED message will
display on the Driver’s Information Center (DIC).
This message informs the driver that turning on the
exterior lamps is recommended. SeeDIC Warnings
and Messages on page 3-67.
Turning the exterior lamp control to off a second
time, or turning on the headlamps will remove the
HEADLAMPS SUGGESTED message in the DIC.
If the parking lamps or the fog lamps were turned on
instead, the HEADLAMPS SUGGESTED message
will continue to be displayed.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Adaptive Forward Lighting System
The Adaptive Forward Lighting System (AFS)
swivels the headlamps horizontally to provide greater
road illumination while turning. AFS will operate
when the vehicle speed is greater than 2 mph (3 km/h).
AFS will not operate when the transmission is in
REVERSE (R). AFS is not immediately operable
after starting the vehicle; driving a short distance is
required to calibrate the AFS. To enable AFS, set the
exterior lamp switch on the multifunction lever to
the AUTO position. Moving the switch out of the
AUTO position will deactivate the system. See
Exterior Lamps on page 3-28.
Fog Lamps
Use fog lamps for better vision in foggy or misty
conditions.
The fog lamps control is located on the multifunction
lever next to the exterior lamp control.
-(Fog Lamps):Turning the band to this position will
turn the fog lamps on.
When you turn the fog lamps on, the fog lamp light will
appear on the instrument panel cluster to indicate
that the fog lamps and the parking lamps are on.
If you turn the high-beam headlamps on, the fog lamps
will turn off. They will turn on again when you switch
to low-beam headlamps.
The ignition must be on for the fog lamps to operate.
The fog lamps will turn off when the ignition is turned off.
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.
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
AUTO 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 3-33
for more information.You can idle the vehicle with the lamps off, even when
it is dark outside. After starting the vehicle, turn the
exterior lamp control band to off, then release it.
The lamps will remain off until you turn the control band
to off again.
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.
SeeDriver Information Center (DIC) on page 3-64to
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 manual parking lamps or headlamps have been
left on, the exterior lamps will turn off as soon as
the ignition is turned off or RAP is active. 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, use the exterior lamp
control to turn the lamps back on.

Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired — by alcohol or drugs, with night vision
problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
Since you cannot see as well, you may need to
slow down and keep more space between you
and other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe place
and rest.
No one can see as well at night as in the daytime.
But as we get older these differences increase.
A 50-year-old driver may require at least twice as much
light to see the same thing at night as a 20-year-old.What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes
will have less trouble adjusting to night. But if you
are driving, do not wear sunglasses at night. They may
cut down on glare from headlamps, but they also
make a lot of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to re-adjust to the dark. When
you are faced with severe glare, as from a driver
who does not lower the high beams, or a vehicle with
misaimed headlamps, slow down a little. Avoid
staring directly into the approaching headlamps.
Keep the windshield and all the glass on your vehicle
clean — inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a lm caused by dust. Dirty glass makes
lights dazzle and ash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that the headlamps light up far less of a
roadway when you are in a turn or curve. Keep your eyes
moving; that way, it is easier to pick out dimly lighted
objects. Just as the headlamps should be checked
regularly for proper aim, so should your eyes be
examined regularly. Some drivers suffer from night
blindness — the inability to see in dim light — and are
not even aware of it.
