Depending on the selected recuperation le vel,the
electric mo tor is operated as an alternator when
in ove rrun mode and during braking in order to
ch arge the high-voltage battery while driving. As
soon as youre lease the accelerator pedal when
th eve hicle is in motion, recuperation in overrun
mode is initiated.
The higher there cuperation, the more sharply the
ve hicle is braked when coasting and the more
electrical energy is fed into the high-voltage bat-
te ry.
The rege nerative brake system has thefo llowing
ch aracteristics:
R supports braking with elect ronically cont rolled
brake forc e boosting
R con verts th e kinetic energy of theve hicle into
elect ric energy %
Ifyo u brake hard, the mechanical brake is
also used. This means that the maximum
re cuperative energy cannot be reco vered. The
more you drive and brake in an anticipatory
manner, the more e1cient lyenergy can be
re cuperated.

The braking e.ect of the electric mo tor during
re cuperation in overrun mode may be reduced or
