Ok... after a pretty long moment of "WTF" I came to the conclusion that "Se tyres tempratur?" means "See tyre temperature?". Yes it is possible, just press F9 while in the car. Also the LFS Wiki may be a good source for answers to your questions. It also explains what isplay#Tyre_temperature" target="_blank">how the F9 menu works.
Hehe yea, sorry, my english is not the best, but its godd you understanded it =) And thanks for the tip and the link.
