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 youta ke your foot o. the accelerator
pedal when theve hicle is in motion and in trans-
mission position h,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 deceleration in overrun mode may not be suf-
fi cient depending on the driving conditions.
Decelerating toa standstill is not possible. Also
brake with the service brake if necessar y.Alw ays
adapt your speed tothe driving conditions and
ke ep a su1cient distance.
The recuperative 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 cann otbe reco vered. The
more you drive and brake in an anticipatory
manner, the more e1cient lyenergy can be
re cuperated.

mal operating temp erature
In these cases, the desired deceleration is set by
