Pontiac 2005 Grand Prix - Manual (Page 122)

When the exterior lamp control is in AUTO and it is dark
enough outside, the DRL will turn off and the low-beam
headlamps at full brightness will turn on. When it is
bright enough outside, the front turn signal lamps will
go off, and the DRL will turn back on. If the vehicle
is started in a dark garage, the automatic headlamp
system will come on immediately. Once the vehicle
leaves the garage, it will take approximately 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
at the highest setting. See Instrument Panel Brightness
on page 3-17.
Vehicle’s sold in the U.S. can turn the DRL off.
To do this, turn the band on the exterior lamp control
to off. Turn the band to this position again to turn the
DRL on.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Light Sensor
The light sensor for the
DRL and AUTO
headlamps feature is
located on top of
the instrument panel.
If the sensor is covered, it will register that it is dark
outside and the headlamps will turn on to full brightness.
Fog Lamps
Fog lamps provide brighter roadway lighting for better
vision in foggy or misty conditions.
- (Fog Lamps): Turn the second band on the
exterior lamps control lever to this position to turn the
fog lamps on. The band will return to its original position.
