funny little knob

[pauldriver152]

hey there. is it possible someone out there could help me. i have a 2009 corsa active 1.2 and there is a little domed knob above the readout for the time/temp/radio station bit. it sits in a sort of grill that looks like a black speaker grill but i dont think it is a speaker. it is on top of the dash in the middle of the car and is just in front of the heater grill for the widscreen. i cannot find anything in the manual so i am begging any of you clever buggers to come to my rescue

thank you loads in advance

hi

I think this is a sensor for your automatic headlights. If you have Auto Hedlights then when it gets dark this tells the Auto lights to turn on.
