Delayed Headlamps - Chevrolet 2004 Classic Owner's Manual

There is a delay in the transition between the daytime
and nighttime operation of the DRL and the Automatic
Headlamp System so that driving under bridges or bright
overhead street lights does not affect the system. The
DRL and Automatic Headlamp System will only be
affected when the light sensor sees a change in lighting
lasting longer than this delay.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave 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,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. See "Instrument
Panel Brightness Control" under Interior Lamps
on page 3-15.
To idle your vehicle with the system off, set the park
brake while the ignition is off. Then start the vehicle. The
system will stay off until you release the park brake.
As with any vehicle, you should turn on the regular
headlamps when you need them.

Headlamps Off in Park (P)
This feature works when the ignition is on and it is dark
outside. To turn the headlamps off when it is dark outside,
turn the exterior lamp control to the parking lamp position.
In this position, the parking lamps, sidemarker lamps,
taillamps, license plate lamps and instrument panel lights
will be on, but the headlamps will be off.
To turn on the headlamps along with the other lamps
when it is dark outside, turn the exterior lamp control to
the AUTO or headlamp position.

Delayed Headlamps

The delayed headlamps feature will continue to
illuminate the headlamps for 20 seconds after the key is
turned to OFF at night. Then the headlamps will
automatically turn off.
To override the 20 second delayed headlamp feature
while it is active turn the switch at the end of the
turn signal/multifunction lever up one position and then
back to AUTO.
