Try doing a search on how to put the car into service mode. It is also explained in the owner manual which, if you don't have one, can be freely downloaded from Rennlist and other sources. There is also a good DIY with pictures at Pedro's Garage.

I notice that most of your questions so far have been answered repeatedly in the forum already, and that you could have easily found the answer yourself using the forum search function . You will find people here much more willing to help you if you at least make some effort to find information yourself first before posting a question, especially one as basic as this one.
