Hi, I've bought second hand Rx400h european model. The thing that I notcied is that after I tunr the car to Ready mode, the gas engine always switch on after some couple of seconds. Isthere anything wrong with my hybrid system? After have driveing the car for a while and if I start the car again then the gas engine won't turn on before many minutes, why is it like that? Do I have to change the aux battery? Apreciate for all replies.
