Light Sensor
The light sensor for the DRL and AUTO headlamp
feature is located on top of the instrument panel. If you
cover the sensor, it will read dark, and the exterior lamps
or the Headlamps Suggested message will appear on the
DIC whenever the ignition is on.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on, the
exterior lamps will turn off approximately 10 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 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.
