GM Owner Manuals - Buick

When the DRL are on, only the low-beam headlamps
will be on. The parking lamps, taillamps, sidemarker and
other lamps will not be on.
When it is dark enough outside, the low-beam
headlamps will come on. The other lamps that turn on
with the headlamps will also turn on. When it is
bright enough outside, the regular lamps will go off, and
the low-beam headlamps change to the reduced
brightness of DRL.
To turn off all exterior lighting at night when the vehicle
is parked, turn the exterior lamp control to the off
position. The exterior lamps will turn back on
automatically when the transmission is moved out of
P (Park). See Exterior Lamps on page 4-11 for
more information.
The regular headlamp system should be turned on
when needed.
Fog Lamps
The fog lamps button is on the exterior lamps control 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 when the fog lamps are in
use. See Instrument Panel Cluster on page 4-31.
The ignition must be in the ON/RUN position for the fog
lamps to work.
The fog lamps will go off when the headlamps are
changed to high-beam.
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.
