Cadillac 2004 Seville - Manual (Page 133)

Light Sensor
The light sensor for the Daytime Running Lamps (DRL)
and the Twilight Sentinel
® is located on the driver’s
side of the front defogger grille.
If you cover the sensor, it will read “dark” and the
exterior lamps or the HEADLAMPS SUGGESTED
message will be on whenever the ignition is on.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off approximately ten
minutes after the ignition is turned to OFF. This
protects against draining the battery in case you have
accidentally left the headlamps or parking lamps on. The
battery saver does not work if the headlamps are
turned on after the ignition switch is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn the
lamps back on. To delay the lamps from turning off, see
Twilight Sentinel
® listed previously in this section.
