Puddle Lamps; Fog Lamps - GMC 2007 Sierra Owner's Manual

To idle your vehicle with the automatic headlamp
system off, turn the control to the off position.
You may be able to turn off your Automatic
Headlamp System. See Daytime Running Lamps
(DRL) on page 222 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 (With DIC Buttons) on page 289.
As with any vehicle, you should turn on the regular
headlamp system when needed.

Puddle Lamps

Your vehicle may have puddle lamps, that come
on when it is dark outside to help you see the area
near the base of the front doors. The puddle
lamps will come on when a door is opened, or
when you press the unlock button on the Remote
Keyless Entry Transmitter. The lamps will time
out or turn off once the engine is started.

Fog Lamps

(Fog Lamps): If your vehicle has fog lamps,
-
the button is located on the instrument panel
to the left of the steering column and below the
dome lamp override button.
The ignition must be in RUN and the parking
lamps must be on for the fog lamps to work.
To turn the fog lamps on, press the fog lamps
button. A light comes on in the instrument
panel cluster to let you know that the fog lamps
are on. Press the button again to turn the fog
lamps off.
When the fog lamps are turned on, the low-beam
headlamps automatically turn on.
The fog lamps turn off while you change to
high-beam headlamps. When the high-beam
headlamps go off, the fog lamps will come
on again.
Fog lamps should only be used in foggy conditions
since they could be distracting to oncoming
drivers in clear weather conditions.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
