Guys, I'm not sure if this question has been asked before. Just too many posts to read thru Anyway, just wondering if you guys know what does the left most button does on dashboard [ Next to hazard light switch ]. My uncle owns a Saga [ 2 yrs old ] and the switch started to blink few days back. He doesnt know what does it mean since according to him, the switch doesnt have a label. Any idea?
