Cadillac 2004 XLR - Manual (Page 136)

Fog Lamps
If your vehicle has fog lamps, use them 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 on the fog lamps.
When you turn on the fog lamps, the fog lamp light on
the instrument panel cluster will come on to indicate that
the fog lamps and the parking lamps are on.
If you turn on the high-beam headlamps, the fog lamps
will turn off. They’ll turn back on again when you
switch to low-beam headlamps.
The ignition must be on for the fog lamps to operate.
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 isn’t covered.
With Twilight Sentinel ® you will see the following
happen:
• When it’s 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’s 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. See “Instrument
Panel Brightness Control” under
Interior Lamps on
page 3-27.
You can idle the vehicle with the lamps off, even when
it’s dark outside. First set the parking brake while
the ignition is in OFF. Then start the vehicle. The lamps
will stay off until you release the parking brake.
