Good day car 2005 model 307cc 2 days ago I parked the car at 12 o'clock at night, after 48 hours, I saw the headlight light in the car park tonight, when I went to the car, I looked at our vehicle. When unlocked and entered, the headlight arm was open. I closed the ignition, I opened the ignition, I saw the text "economy mode ..." I don't understand, can parks last 48 hours? How did the battery not run out? And it is impossible not to notice the warning signal when getting out of the car at night.
