Volvo 480 Club Europe

I've replaced my dead 480 Turbo with a GT and on the heated seats button plate, there is an extra button. It looks like a spotlight button. http://www.webvalley.co.uk/button.png
What does it do. I can't see anything obvious?

thanks
Jim

Put the headlights up
Select high beam (indicator stalk)
Operate the switch you found. It controls whether or not your long-range driving lamps (next to Day running lights) come on with the high-beams or not.

I can't see why it would ever need to be in the off position.

Every 480 has this switch, but I can see why you would have missed it as it just needs left in the on position and that's it!

thanks for that. My turbo had a neat little home made switch there when I got it, which bypassed the standard horn to a very loud two tone horn (illegal me thinks). I removed that and stuck to the standard horn. All makes sense now.
thanks again

You're welcome.
