Extended Range Mode
When the vehicle reaches the end of its electric range, it switches to extended range mode. In this mode, electricity is produced by the motor generator which is driven by the internal combustion engine (ICE). This secondary source of electric power extends the vehicle range. Operation will continue in extended range mode until the vehicle can be plugged in to recharge the high voltage battery and restore electric mode.
The high voltage battery will continue to provide some power and work together with the ICE to provide peak performance when it is required, such as driving up a steep incline or during high acceleration. The high voltage battery will not be recharged while in extended range mode.
