Daytime Running Lamps (Drl); Automatic Headlamp System - Pontiac 2006 GTO Owner's Manual

Daytime Running Lamps (DRL)

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.
The DRL system will make your low-beam headlamps
come on at a reduced brightness when the following
conditions are met:
•
The ignition is on.
•
The exterior lamp control is turned to AUTO and
the light sensor detects daytime light.
•
The exterior lamp control is turned to the off position.
•
The parking brake is released.
•
For vehicles with automatic transmissions, the shift
lever is not in PARK (P).
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps, and instrument panel lights will not
be illuminated unless you have turned the exterior lamps
control to the parking lamp or headlamp position.
The DRL system will remain off any time your vehicle is
in PARK (P) or the parking brake is engaged the first
time the ignition is turned on.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Automatic Headlamp System

When it is dark enough outside, your Automatic
Headlamp System will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps, and the
instrument panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor on the
top of the instrument panel under the defroster
grill. Make sure it is not covered, which will cause the
system to be on whenever the ignition is on.
The system may also be on when driving through a
parking garage, heavy overcast weather, or a tunnel.
This is normal.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately.
As with any vehicle, you should turn on the regular
headlamps when you need them.
The headlamps can be set to come on at different
levels. The sensitivity can be adjusted to Early, Normal,
or Late. See Vehicle Personalization on page 2-31 .
Leaving the headlamps and parking lamps on when the
engine is not running will eventually drain the battery.
To prevent the battery from draining, the headlamp and
parking lamps will turn off when the ignition has been
turned off and the driver's door is opened, because the
vehicle senses that the driver has forgotten to turn
off the lights.
