Depending on the selected recuperation le vel,
th e electric mo tor is operated as an alternator

order tocharge the high-voltage battery while
driving. As soon as youre lease the accelera tor

The braking ef fect of the electric mo tor during
re cuperation in overru n mode may be reduced or

In these cases, the desired deceleration is set by

Manually setting recuperative deceleration
Yo u can use thesteering wheel gearshift paddles
to manually adju stthe intensity of recuperation

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