The lettering in the segment will light up brightly,
the outer edge will light up and the segment will
ll up when the following driving style is adopted:
1 Steady speed
R
2 Gentle deceleration and rolling
R
3 Moderate acceleration

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
R
2 Heavy braking
R
3 Sporty acceleration

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

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 xed reduction in consumption.

Depending on the selected recuperation level, the
electric motor is 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 release the accelerator pedal when
the vehicle is in motion, 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 regenerative 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
ybrid) id)
manner, the more e ciently energy can be
recuperated.

The braking e ect 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

if the high-voltage battery is not yet at a nor-

In these cases, the desired deceleration is set by
the brake control system. Also brake with the
service brake if necessary.
