Fog Lamps - GMC 2006 Yukon XL Owner's Manual

Fog Lamps

If your vehicle has fog lamps, use them for better vision
in foggy or misty conditions.
Your parking lamps and/or low-beam headlamps must
be on for your fog lamps to work.
3-18
The fog lamp button is
located on the left side of
the instrument panel.
Press the button to turn the fog lamps on. Press the
button again to turn them off. An indicator light will glow
in the button when the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps
in the dark without turning on your headlamps.
The fog lamps will go off whenever your high-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.
The fog lamps will be cancelled after the ignition is
turned off. If you still want to use the fog lamps after
you restart the vehicle, you will need to press the
fog lamp button again.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
