Functions of the operating modes
The operating mode determines the drive type of the plug-in hybrid vehicle.
The following operating modes are available: HYBRID | For economical driving with availability of all hybrid functions Default setting when starting the vehicle. All drive types (combustion engine, electric drive, boost and recuperation) are available. The hybrid system selects the most suitable drive type according to the driving situation and road conditions.
|
E-MODE | Driving by electric propulsion only Driving by electric propulsion is possible up to the pressure point of the haptic accelerator pedal. Beyond the pressure point of the haptic accelerator pedal, the combustion engine is activated. Use: in inner city/low emission zone or when the charge level of the battery permits use of the electric drive.
|
E-SAVE | The charge level of the battery is maintained Use of the electric drive and boost is restricted. The charge level of the high-voltage battery is maintained, e.g. for subsequent use in the inner city/low emission zone.
|
CHARGE | The battery is charged by the combustion engine while driving |
In drive program and all operating modes are available.
The HYBRID operating mode is active during manual gearshifting.
In the automatic drive programs and the HYBRID operating mode is active.
System limitations
An operating mode may not be available under the following circumstances:
The high-voltage battery's charge level is too high or too low.
The combustion engine is not yet at operating temperature.
The outside temperature is too high or too low.
The self-diagnosis functions are active.
