Hi Jvdeuce .The blue light is the temperature light to say the engine is running cold .When the engine heats up the light goes out.They don't have a temperature gauge as most cars do .
For the green "Key" light I would download the owners & repair manual for the 2009 model cube that is available in english & have a read
Have a good day
