Delayed Headlamps - Buick 2004 Century Owner's Manual

Delayed Headlamps

Delayed headlamp illumination provides a period of
exterior lighting as you leave the vehicle's area.
The feature is activated when the vehicle's ignition is
turned off and the headlamps are on due to the
automatic headlamp control feature described previously
in this section. The headlamps will remain on until the
exterior lamps control is moved from OFF to the parking
lamp position or until a 90 second lighting period has
ended.
If the ignition is turned off while the exterior lamps
control is in the parking lamp or headlamp position, the
delayed headlamp illumination cycle will not occur.
This feature can be turned on or off by doing the
following:
1. Turn the ignition key to RUN.
2. Close all the doors.
3. Press and hold the LOCK position on the power
door lock switch. While holding the LOCK position
on the door lock switch, cycle the exterior lamps
control on and off two times.
3-14
4. Release the power door LOCK switch. These steps
must be carried out in a time period of less than
10 seconds, followed by a delay period of no more
than 10 seconds.
5. Then, press and hold the unlock position on the
power door switch. While holding the unlock
position, turn the exterior lamps control on and off
two times. Release the unlock position on the power
door switch. These operations must be carried
out in a time period of less than 10 seconds.
After releasing the unlock position on the power door
switch, a single chime will be heard if the delayed
headlamp illumination function has been turned off.
Two chimes will be heard if the feature has been turned
on. Disconnecting the vehicle's battery for up to a
year will not change the programmed operation for this
feature.
