Courtesy Lamps; Interior Lamps; Instrument Panel Brightness Control - Chevrolet 1999 Lumina Owner's Manual

When the DRL are on, only your reduced intensity
-
high beam headlamps will be on. The taillamps,
sidemarker and other lamps won't be on. Your
instrument panel won't be lit up either.
When it's dark enough outside, your DRL will turn off
-
and your low beam headlamps will illuminate. The
other lamps that come on with your headlamps will also
come on.
When it's bright enough outside, the low
headlamps will go out, and DRL illuminates your
-
high beam headlamps at reduced intensity.
To idle your vehicle with the DRL off, set the parking
brake while the ignition is in OFF or LOCK. Then start
your vehicle. 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.

Instrument Panel Brightness Control

You can brighten or dim the instrument panel lamps by
moving the dial (A), located next to the exterior lamps
controls. If you turn the dial all the way up, your
courtesy or interior lamps will come on.

Courtesy Lamps

When any door is opened, several lamps will come on.
These lamps are courtesy lamps. They make it easy for
you to enter and leave your vehicle. You can also turn
these lamps on by moving the dial near the headlamp
knob all the way up.
Some of the lamps have switches so you can turn them
on even when the doors are closed. These lamps are
-
beam
reading lamps. To avoid draining your battery, be sure to
turn off all the reading lamps when leaving your vehicle.
