Automatic Headlamp System - Pontiac G6 2009 Owner's Manual

The DRL system makes the low-beam headlamps come
on at a reduced brightness when the following conditions
are met:
•
The ignition is on.
•
The exterior lamps control is in AUTO.
•
The exterior lamps control is in the parking lamps
only position (This applies only to vehicles that are
first sold in Canada).
•
The light sensor detects daytime light.
•
The parking brake is released or the vehicle is not in
P (Park).
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps, and instrument panel lights are
not on unless you turn the exterior lamps control to the
parking lamp position.
The regular headlamp system should be turned on
when they are needed.

Automatic Headlamp System

When it is dark enough outside, the automatic headlamp
system turns on the 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.
The vehicle has a light sensor on top of the instrument
panel that controls the automatic headlamp system.
Do not cover the sensor or the automatic headlamp
system will turn on when it is not needed.
There is a delay in the transition between the daytime
and nighttime operation of the DRL and the automatic
headlamp systems so that driving under bridges or
bright overhead street lights does not affect the system.
The DRL and automatic headlamp systems will only
be affected when the light sensor sees a change
in lighting lasting longer than this delay.
If vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it takes about one minute
for the automatic headlamp system to change to DRL
if it is light outside. During that delay, the instrument
panel cluster may not be as bright as usual. Make sure
the instrument panel brightness control is in the full bright
position. See Instrument Panel Brightness on page 3-16.
