You'll have to forgive me as I'm going from memory here
On my Lag when the ignition is turned I get the following lights;
and probably some more.
I would envisage that you should have at least those above come on when you turn the ignition. It may well be that some bulbs have gone on the dash.
If this is the case I would be seriously concerned that there could be something wrong that needs immediate attention hence why the STOP light is illuminating (obviously this is what you want to know but without the other tell tale light it's impossible to tell).
I assume you have checked all you're levels - Brake Fluid, Coolant etc.....
