I've had my car for a few days now and i cant figure out the auto headlamp/fog lamp situation. when i have the headlights on AUTO and the fog lamps on auto both headlamp and fog lamp turn on even during the day. if i have the fog lamp off and headlamp on auto the fog would only come on when i turn it on. i've looked through the manual which doesn't really give me much info. am i stupid? or is it not possible to have the headlamp/fog lamp both on AUTO mode?
