from what i remember reading the auto lights should have the functions
- auto on when unlocking in low light
- follow you home when locking the car in low light
- auto on for a period of time spend over 90mph but will switch off when
you stay under 10mph (not sure but i think its 10mph) for 5 minutes
- auto on in dazzle conditions, ie bright sunlight
- auto on in low light
this is with the switch into the auto postition btw
they should also auto level from ignition with a minimum of 2 movements
edit: is your windshield clean? the sensor lives on the reverse of your rear view mirror facing out behind the glass, as you look into your car from the front its the dark square patch in the middle at the top
