The lettering in the segment will be grey, the outer
edge will be dark and the segment will empty
when the following driving style is adopted:
1 Fluctuations in speed

2
Heavy braking
R
3 Sporty acceleration

The ECO display will show you when you have
driven economically:
The three segments will fill up completely at

the same time
The edges around all three segments will light

up
The additional range achieved as a result of your
driving style in comparison with a driver with a
very sporty driving style will be shown in the
centre of display 4. The range displayed does
not indicate a fixed reduction in consumption.
Recuperative brake system
▌Function of the recuperative brake system
Depending on the selected recuperation level, the
electric motors 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 you take your foot off the accelerator
pedal when the vehicle is in motion and in trans-
mission position h, recuperation in overrun
mode is initiated.
The higher the recuperation, the more sharply the
vehicle is braked when coasting and the more
electrical energy is fed into the high-voltage bat-
tery.
The deceleration in overrun mode may not be suf-
ficient depending on the driving conditions. Decel-
erating to a standstill is not possible. Also brake
with the service brake if necessary. Always adapt
your speed to the driving conditions and keep a
sufficient distance.
The recuperative brake system has the following
characteristics:
supports braking with electronically controlled
R
brake force boosting
converts the kinetic energy of the vehicle into
R
electric energy
% If you brake hard, the mechanical brake is
also used. This means that the maximum
recuperative energy cannot be recovered. The
more you drive and brake in an anticipatory
manner, the more efficiently energy can be
recuperated.
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:
when the high-voltage battery charge level
R
increases
if the high-voltage battery is not yet at a nor-
R
mal operating temperature
In these cases, the desired deceleration is set by
the brake control system.
