Congratulations on your purchase! What model? 
Firstly, around 2 weeks back this "-------" has now changed to 11. Don't know what it was, but it changed.
Secondly, I myself don't fill exactly 3 litre. Keep it a bit on the lower side like around 2.5-2.8. Don't fill over the MAX mark.
Thirdly, Since there are no ABS brakes, I don't think the light will come on with all the others. Mine also don't come on.
Regards.
