I recently moved the front passenger seat forward and back to show a friend how much room was in the back of my iQ. Now the seatbelt warning light and passenger air bag 'on' display lights remain on even though there is nothing/no one in the seat. I have to hook up the seatbelt on an empty seat to stop all the annoying warnings. Is this due to loose wiring or some faulty switch? Can anyone share a solution? THANKS!
