Operation Manual

Observe the "Important safety notes" section
for driving safety systems (Y page 62).
The Recuperative Brake System converts the
kinetic energy when braking into electrical
energy. The electric motor is used as an alter-
nator during braking. This electrical energy is
then stored in the high-voltage battery.
You can find information about manually
adjustable recuperation under "Steering
wheel paddle shifters" (Y page 138).
If the warning light in the instrument cluster is
lit up, there is a motor malfunction or a brake
malfunction.
Observe information regarding indicator and
warning lamps (Y page 229) as well as dis-
play messages (Y page 201).
