Daytime Running Lamps; Cornering Lamps - Buick 2004 LeSabre Owner's Manual

Daytime Running Lamps

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 and
®
Twilight Sentinel , so be sure it is not covered.
The DRL system will make your high-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 transaxle is not in PARK (P).
When the DRL are on, only your high-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps will not be on.
When it is dark enough outside, your low-beam
headlamps will come on. The other lamps that turn on
with your headlamps will also turn on. When it is
bright enough outside, the regular lamps will go off, and
your high-beam headlamps change to the reduced
brightness of DRL.
To turn off all exterior lighting at night when you are
parked, turn off the headlamps and move the Twilight
®
Sentinel lever all the way toward OFF. The exterior
lamps will turn back on automatically when you move
the transaxle out of PARK (P).
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Cornering Lamps

If your vehicle has this feature, the cornering lamps
come on when the headlamps or parking lamps are on
and you signal a turn with the multifunction lever.
They provide more light for cornering.
