My Range Extender Menu has been enabled . But greyed out and unavailable when the state of charge is above 75%
However, when the charge falls bellow 75% , and the Range Extender becomes available, it is checked
to activate Hold State of Charge
BUT the Range Extender Does not Fire up. WHY ??? I really need to be able toggle between REX and EV any time below 75%
Other times such as periodic maintenance, the REX automatically operates for some 15mins ,
(And when REX is manually activated using the Brake & Power pedal sequences, the engine fires up as intended)
So .. why does the REX not operate when the Hold State of Charge is enabled ?? which is it meant to do?
can anyone help??
