Hello, I own a 2005 Volvo S60 2.5T. I have had several concerns with the safety restraint system. Number one I have always noticed that the seat belt remind never comes on. You can forget to wear your seat-belt and it never tells you. Second, the passenger air bag off light never comes on. I am concerned about this because I am scared the air bag is always on and if I was in a collision and the passenger air bag deployed with nobody in the seat it would most likely ruin the entire dash and bust the windshield for no reason. Third, the door locks never automatically lock at any speed. I am not sure if this is at all related. Also, my turn signals used to flash quickly when I locked the doors now the car does nothing when I lock the doors. Any advice is welcome!

 

Have you check the owners manual to see what it says about your issues/concerns?
