Pontiac Sunfire 2003 Owner's Manual page 117

A flashing DRL telltale indicates a possible burned out
headlamp, or that the vehicle may need service to repair
a stuck DRL relay.
When the DRL are on, your low-beam headlamps will
be on at a reduced brightness. The taillamps,
sidemarker and other lamps won't be on. Your
instrument panel won't be lit up either.
When you turn the exterior lamp band to the headlamp
position, your low-beam headlamps will come on.
The other lamps that come on with your headlamps will
also come on.
When you turn off the headlamps, the regular lamps will
go off, and your low-beam headlamps will come on to
the reduced brightness.
To idle your vehicle with the DRL off, set the parking
brake. The DRL will stay off until you release the parking
brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
This indicator light on your
instrument panel cluster
will come on when the DRL
are on.
Fog Lamps
If your vehicle has this feature, use your fog lamps for
better visibility in foggy or misty conditions.
Push the top of the button to turn the fog lamps on. Push
the top of the button again to turn the fog lamps off.
When using fog lamps, the parking lamps or low-beam
headlamps must be on.
A light on the button will come on when the fog lamps
are actually on. Fog lamps will go off whenever the
high-beam headlamps come on. When the high-beam
headlamps go off, the fog lamps will come on again.
Continuous use of the fog lamps will shorten bulb
life. Limit use as necessary.
The button for your fog
lamps is located next to
the instrument panel
brightness control.
