Automatic Light Control/
Daytime Running Lamps (DRL)
Your Alero is equipped with Automatic
Light Control (ALC) for night driving and
Daytime Running Lamps (DRL) for day-
time driving. The ALC activates full exte-
rior lighting — including headlamps and
instrument panel lighting — the same as
activating the headlamp switch located
on the left stalk of the steering column.
The DRL system activates your head-
lamps at reduced intensity when the
ignition is ON, the headlamps switch is
OFF, the shifter is not in Park and the
park brake is released. When it's dark
enough outside, the DRL will turn off
and the vehicle's full intensity head-
lamps and parking lamps will activate.
When it's bright enough outside, the full
intensity headlamps and parking lamps
will go off and the reduced intensity
headlamps (DRL) will come on.
Note: The Automatic Light Control
system may temporarily switch your
vehicle's headlamps and interior lights
— including the radio display — to the
nighttime mode when you pass through
a darker ambient condition, such as
under a bridge or through a tunnel. This
should last no longer than 45 seconds.
Delayed Headlamps Off
Your vehicle's Delayed Headlamp Off
feature provides illumination when exit-
ing your Alero. When you turn the igni-
tion to OFF (while in the Automatic Light
Control mode), the headlamps will
remain on as courtesy lighting for 20
seconds. The headlamps will turn off
automatically after 20 seconds with no
further action on your part.
Overriding the Systems
If you prefer not to use Automatic Light
Control, the DRL or Delayed Headlamps
Off feature, you can temporarily over-
ride the systems by following these
procedures:
• Automatic Light Control (ALC):
Under nighttime lighting conditions,
activate the parking brake by pulling
the hand lever before turning the igni-
tion ON. Notice that activating the
parking brake while in ALC will not
override this feature.
• Daytime Running Lamps (DRL):
Under daytime lighting conditions,
place the shifter in Park or activate
the park brake as described above.
Note that the DRL will activate
with the park brake applied and the
vehicle speed above 3 mph.
• Delayed Headlamps Off: With the
headlamps ON after the ignition is
OFF, rotate the headlamp stalk switch
from OFF to PARKLAMPS to OFF to
immediately turn off the headlamps.
