If yo u lea veyour foot on the brake pedal when
driving, the brake system may overheat.

Depending on the selected recuperation le vel,the
electric mo tors are operated as an alternator when in
overrun mode and during braking in order
to charge the high-voltage battery while driving.
As soon as youre lease the accelerator pedal
when theve hicle is in motion, recuperation in
ove rrun 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 force 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. Driving and parking
