R
Converts the kinetic energy of the vehicle
into electric energy
In the
Î
drive program you can use the steer‐
ing wheel paddle shifters to manually adjust the
intensity of recuperation in overrun mode
(

page 29).
System limits
The braking effect of the electric motor during
recuperation in overrun mode may be reduced or
may not be available at all in the following situa‐
tions:
R
When the high-voltage battery charge level
increases
R
If the high-voltage battery is not yet at a nor‐
mal operating temperature
R
When driving at speeds close to zero
R
In transmission position
i
R
During and after ESP
®
intervenes
In these cases, the desired deceleration is set by
the brake control system. Also brake with the
service brake if necessary.
Manually setting recuperative deceleration
In the
Î
drive program can use the steering
wheel gearshift paddles to manually adjust the
intensity of recuperation in overrun mode.
The higher the recuperation, the more sharply
the vehicle is braked when coasting and the
more electrical energy is fed into the high-volt‐
age battery.

cally set after a restart of the engine or after
