Puddle Lamps; Fog Lamps - GMC Yukon Denali 2006 Manual

You may be able to turn off your Automatic Headlamp
System. See Daytime Running Lamps (DRL) on
page 3-15 for more information.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the Driver
Information Center (DIC). See DIC Vehicle
Customization on page 3-59.
As with any vehicle, you should turn on the regular
headlamp system when you need them.

Puddle Lamps

Your vehicle may be equipped with puddle lamps to
help you see the area near the base of the front doors
when it is dark out. The puddle lamps will illuminate
when a door is opened, or when you press the unlock
button on the keyless entry transmitter. The lamps
will time out or turn off once the engine is started.

Fog Lamps

Use the fog lamps 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.
Press the button to turn the fog lamps on while the
headlamps or parking lamps are on. Press the button
again to turn them off. An indicator light will glow
near 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 the 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.
The fog lamp button is
located on the left side of
your instrument panel.
