The boost function is activated when the accelerator pedal is pressed a long way down (kick-down). For full acceleration, the vehicle is simultaneously driven by both the combustion engine and the electric motor. The boost function is only available for a short time as it uses a lot of energy. Its availability is dependent on the charge level of the high-voltage battery.

The combustion engine is switched off and disengaged when the selector lever is in position D, the accelerator pedal is not being pressed and the vehicle s speed is up to approx. 180 km/h. This makes it possible to reduce fuel consumption by thinking ahead.

When the vehicle brakes, electrical energy is produced by the electric motor (which is in this case working as a generator) and used to charge the high-voltage battery. This also happens if the vehicle is going downhill or is coasting in gear (overrun).

If you brake early and smoothly, the vehicle is braked by the electric motor -2- Fig. ►. This means that a large amount of the kinetic energy can be recovered and used as electrical energy to charge the high-voltage battery. Under heavy braking, the normal brakes are also activated.

The degree of recuperation can vary depending on whether:

The amount of energy recovered is shown on the instrument cluster/infotainment display in the energy flow display link►.
