EV Mode Input Switch (PHEV Only)

Electric Vehicle (EV) Mode is driver-selectable switched input that determines the driver's request for one of the three EV driving modes: Auto  - this is normal PHEV operation (charge depleting) which attempts to minimize use of internal combustion engine operation until PHEV battery is mostly depleted then reverts to conventional hybrid (charge sustaining) operation, EV Now  - this mode forces the internal combustion engine off under all non-faulted driving conditions, and EV Later  - this mode forces the vehicle into conventional hybrid (charge sustaining) to allow a reserve of battery energy to be used later once driver selects Auto mode again.
