Buick 2009 Lucerne - Manual (Page 157)

Fog Lamps
For vehicles with fog lamps, the button is located on the
exterior lamps control. The exterior lamps control is
located on the instrument panel to the left of the steering
column.
#
(Fog Lamps): Press the exterior lamps button to
turn the fog lamps on or off. A light comes on in
the instrument panel cluster to show that the fog lamps
are on. See Instrument Panel Cluster on page 3-35.
The ignition must be in the ON/RUN position and
the parking lamps must be on for the fog lamps to
illuminate.
The fog lamps will go off while you change to high-beam
headlamps.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Cornering Lamps
For vehicles with this feature, the cornering lamps come
on when: the headlamps or parking lamps are on, the
vehicle is not in P (Park), and you signal a turn with the
turn signal/multifunction lever. They provide more light
for cornering.
Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off about 10 minutes after the ignition
is turned to LOCK/OFF and a door has been opened.
This protects against draining the battery if the
headlamps or parking lamps are accidentally left on.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn the
lamps back on after the ignition is turned to LOCK/OFF
and any door is opened.
Instrument Panel Brightness
D
(Instrument Panel Brightness): This feature
controls the brightness of the instrument panel lights.
The knob for this control is located next to the exterior
lamps control.
Push the knob in and release when it pops out.
Turn the knob clockwise to increase the brightness of
the instrument panel lights and counter clockwise to
decrease the brightness. Turning the knob completely
clockwise to the detent will turn on the courtesy lamps.
