I need to know how is the oil light reset procedure and if it is necessary turn the air bag suspension off when lifting the vehicle and how to do it.
Thank u very much 4 your help

I was told that my 2007 R500 needed a new transmission. the car has 60,000 miles on it. Is this normal and how much does this cost?
