command master lighting returns to continuous light. The function is disabled.
If the control lever is shifted from "Forwards" to "Reverse" or vice versa during the
"Warming Up" function, the "Warming Up" function stops automatically when position
"À neutral" is reached. When position "Á gearbox forwards / reverse" is reached
