Headlamps On Reminder; Daytime Running Lamps (Drl) - Buick 2008 Lucerne Owner's Manual

Headlamps on Reminder

If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver's door, you will hear a continuous
warning chime. The chime will turn off when the
lamps are turned off.

Daytime Running Lamps (DRL)

Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
first sold in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL, so
be sure it is not covered.
3-16
The DRL system makes the low-beam headlamps turn
on at reduced brightness in daylight when the
following conditions are met:
•
The ignition is on.
•
The exterior lamp button for the headlamps is off.
•
The automatic transmission is not in PARK (P).
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
PARK (P). See Exterior Lamps on page 3-14 for
more information.
As with any vehicle, the regular headlamp system
should be turned on when needed.
