Lamps On Reminder; Interior Lamps - Chevrolet TRACKER 2000 Manual

Automatic Light Control (ALC)
Your vehicle is equipped with an automatic light
sensor on top of the instrument panel, so be sure it
is not covered. If it is, the nighttime lights will remain
on continuously.
When it is dark enough outside, your ALC will turn on
-
your low beam headlamps at the normal brightness
along with other lamps such as the taillamps,
sidemarker, park lamps and instrument panel lights.
There is a short delay in the transition between daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the ALC systems. If the light sensor senses
a reduction in lighting that lasts longer than 5 seconds,
it will activate the nighttime lamps. If you are driving
through a parking garage, heavy overcast weather or a
tunnel, the ALC will turn on your low
at a normal brightness along with the taillamps,
sidemarker, park lamps and the instrument panel lights.
The radio lights will be dimmer.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
