Daytime Running Lamps - GMC C series 2002 Owner's Manual

Headlamps On Reminder (If Equipped)
If you have this system, a tone alarm will sound when
your headlamps and/or parking lamps are turned on and
your ignition is in LOCK or ACC.

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.

The low beam headlamps will come on at
reduced brightness in daylight when the following
conditions are met:
D
The ignition is on,
D
the headlamp switch is off, and
D
the parking brake is released.
When the DRL are on, only your low
will be on. The exterior lamps won't be on. Your
instrument panel won't be lit up either.
When it begins to get dark, your DRL indicator light is
a reminder to turn your headlamp switch on. The other
lamps that come on with your headlamps will also
come on.
When you turn the exterior lamp switch off, the regular
lamps will go off, and your low
change to the reduced brightness of DRL.
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.
