I just bought a used Volvo and do not know what "W" and "S" on the middle console are used for. Also, the radio does not work. Is there a way I can pull radio out to check for problem?

Hi. I own a 99 Volvo S70 and on the shift console, there's a button with a "W" on it which is used for winter driving. It basically tells the transmission to be soft and not as responsive as it should be which helps you keep more traction in winter driving. If you're used to driving in winter conditions like me, I don't use mine much.

The "S" is a shift overlock button which prevents the transmission from going into overdrive. Often times, when people pull a trailer or have heavy loads, it prevents the transmission from overheating resulting in premature wear.

I hope this helps.
