Hummer 2007 H3 - Manual (Page 167)

Fog Lamps
Your vehicle has fog lamps. You can 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.
The fog lamp button
is located in the
exterior lamps control.
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 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 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.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Instrument Panel Brightness
D (Instrument Panel Brightness): This feature
controls the brightness of the instrument panel
lights.
The thumbwheel for this feature is located next to
the exterior lamp control.
Turn the thumbwheel up or down to brighten or
dim the instrument panel lights and the radio
display. The instrument panel lights, cluster, and
radio display do not dim to complete darkness.
Turn the thumbwheel all the way up to turn
the dome lamps on.
Dome Lamp
The dome and footwell lamps will come on when
you open a door. The dome lamps are located
in the cargo and front area of the vehicle.
You can also turn the dome and footwell lamps
on by turning the thumbwheel, located next to
the exterior lamps control, all the way up. In this
position, the lamps will remain on whether a
door is opened or closed.
