On the selector lever: connect the

On the instrument panel display: indi-

ation levels. The brake energy recuperation can generate
a br
aking eff
ect. This braking effect depends
on the selected driving programme and the
level of charge of the high-voltage battery. When braking the vehicle and when the vehi-
cle mo
ves by inertia or travels downhill in the
deceleration phase, electric power is gener-
ated by the electric engine and stored in the
high-voltage battery. The electric engine
then operates as an alternator and produces
a engine brake effect. This process is called
brake energy recuperation.
The status of the recuperation is indicated in
the power display of the instrument panel
››› page 61. When recuperation is active, the
needle goes to the green area of the display.
The current recuperation level is displayed on
the instrument panel display ››› Fig. 136.
Given the case, in the application installed on
the smartphone you can view a statistic of
the energy recuperated over the last 30 mi-
nutes. Check the electronic instruction man-
ual of the application for this.
The effect of the engine brake is more or less
intense depending on the level of recupera-
tion. If the recuperation is very intense, the
brake light of the vehicle may also be switch-
ed on. As the charge level of the high-voltage
battery increases, the recuperation reduces
and, thus, the effect of the engine brake.
When the high-voltage battery is fully charg-
ed, no energy recuperation takes place and
the effect of the engine brake is not available.
When the vehicle detects that road condi-
tions do not allow safe contact between the
wheels and the road, the energy recupera- tion is automatically reduced and, therefore,
the effect of the engine br

There are a total of 4 brake energy recupera-
tion levels. You can switch between recupera-
tion levels 1 to 3 by pressing the selector lever
