Daytime Running Lamps; Lamps On Reminder - Pontiac 2003 Vibe Owner's Manual

Automatic Light Control (ALC)
Your vehicle is equipped with an automatic light sensor
on the top left corner of the instrument panel, so be
sure it is not covered or the headlamps will be 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, parking lamps and instrument panel lights.
The parking brake must be released for ALC to work.
This is indicated by the headlamp symbol on your
instrument panel cluster.
If you are driving through a parking garage, overcast
weather, or a tunnel, the ALC may turn on your
-
low beam headlamps at a normal brightness along with
the taillamps, sidemarker, parking lamps and the
instrument panel lights. The radio lights will be dimmer,
and the instrument panel cluster lights may dim. There
will be a 10 to 15 second delay before the lights will
turn on when starting the car at night.

Lamps On Reminder

If you turn the ignition to LOCK or ACC and leave
the lamps on, you'll hear a tone when you open the
driver's door.

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 DRL system will make your headlamps come
on at a reduced brightness when the following
conditions are met:
D
The ignition is on with the engine running,
D
the exterior lamps switch is off and
D
the parking brake is released.
When the DRL are on, only your 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 switch to the headlamp
position, your DRL will go off and your headlamps will
come on. The other lamps that come on with your
headlamps will also come on.
