"Hold" and "Charge" function

Battery level sustained for later use.

The function maintains the charge in the hybrid battery for electric operation saves available electrical energy for later use, e.g. for driving in an urban environment or through a residential area. Hold is available regardless of the hybrid battery's state of charge.

The car works as for normal hybrid operation with discharged battery where, in addition to re-using brake-generated energy, for example, the car starts the internal combustion engine more often in order to maintain the charge in the battery.

Engine charges hybrid battery.

The function charges the hybrid battery with support from the internal combustion engine for using increased electric operation at a later time. The function is not available when the hybrid battery already has a high charge level.
