Depending on the selected recuperation le vel,
th e electric mo tor is operated as an alternator
when in overru n mode and du ring braking in
order tocharge the high-voltage battery while
driving. As soon as youre lease the accelera tor
pedal when theve hicle is in motion, recupera‐
tion in overru n mode is initia ted.

trolled brake forc e boosting
R con verts th e kinetic energy of theve hicle

In the drive program, you can use thesteering

Sy stem limits
The braking ef fect of the electric mo tor during
re cuperation in overru n mode may be reduced or
may not be available at all in thefo llowing situa‐

inc reases
R ifth e high-voltage battery is not yet at a nor‐
mal operating temp erature
R when driving at speeds close tozero
R in transmission position i

In these cases, the desired deceleration is set by
th e brake control sy stem. Also brake with the
service brake if necessar y.
Manually setting recuperative deceleration
Yo u can use thesteering wheel gearshift paddles
to manually adju stthe intensity of recuperation
in ove rrun mode. The higher

th eve hicle is braked when coasting and the
more electrical energy is fed into the high-volt‐

conside rably or result in braking only on one
side
R maintain a much greater safe dis tance tothe
