I have this light on in my Honda fit but I do not know what to do. Need your help please.
Yep, that means the gearbox oil is due for replacement. It comes on after the appropriate distance interval since the last change has been covered, if I recall correctly the number indicates how far over the interval you've driven. If I'm right on that I think you need to get the fluid changed ASAP, 4600km over is really far!
