Cadillac 2007 XLR - Manual (Page 168)

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 about one minute for the automatic headlamp
system to change to DRL if it is light outside.
