Brake energy recuperation (charging)
When braking the vehicle, electric power is
generated through the electric engine and
stored in the high-voltage battery
››› page 139. This also occurs to a lesser ex-
tent when the vehicle moves by inertia or
drives downhill in the deceleration phase.
As the charge level of the high-voltage bat-
tery increases, the recuperation reduces and,
thus, the effect of the engine brake. When the
high-voltage battery is fully charged, no en-
ergy recuperation takes place and the effect
of the engine brake is not available ››› .
The ener gy r

ecuperation can be displayed
on the instrument panel display or in the ap-
plication installed on the smartphone. Slow travel function
The slo

w travel function consists of driving
slowly, at about 5 km/h (3 mph), forward or
reverse without pressing the accelerator ped-
al.
The slow travel function is activated automat-
ically:

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
ake ››› .

ecuperation level
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

Note
If the selector lever is left for a long time in
a position other than P with the ignition off ,
the 12-v

Driving down slopes
The st
eeper the sl

ope, the higher the selected
brake energy recuperation level will have to
be. A high recuperation level increases the
braking effect of the electric engine. Never let
the vehicle roll downhill with the selector lev-
er in the neutral position N.

Braking and parking
If the electromechanical brake servo is not
w orking, the br
ake pedal must be pressed
harder, as the braking distance increases due
to the lack of assistance from the servo brake.
Brake blending
The brake energy recuperation can generate
a braking effect ››› page 139. This braking ef-
fect depends on the selected driving pro-
gramme and the level of charge of the high-
voltage battery. If the braking effect caused
by the recuperation is very intense, the vehi-
cle’s brake lights with turn on. The electric en-
gine, when operating as an alternator, can
generate braking torque on the front wheels
based on the RPM and the temperature and
charge level of the high-voltage battery.
These variable parameters cause fluctuating
electric decelerations which are hydraulical-
ly compensated according to the driver’s de-
sires. This function is called “brake blending”
and it combines mechanical braking with the
engine brake effect. WARNING
Driving at high speed on icy, slippery wet
gr ound can r

esult in loss of vehicle control
and serious injury to the driver and passen-
gers.

Charge options

High-voltage battery
Batteries age based on their use and their
oper ating time
. It is advisable that you know
certain details regarding the correct handling
and care of the high-voltage battery so this
remains in good condition for longer and can
be used in a reliable manner. Carefully read
the following information and take into ac-
count the indications when using the vehicle. WARNING
If the battery is charged in an inappropriate
manner , if no consider

ation is given to the
general safety measures, power sockets
and charging cables in poor condition are
used or the high-voltage battery is used in
an inadequate manner, this could lead to
short circuits, electrical shocks, explosions,
fires, burns and serious injuries, even death.

Practical tips
CAUTION
Leaving the vehicle parked for a long peri-
od of time with the high-v olt
age battery
discharged may cause irreversible damage
to the battery. · Always charge the high-
voltage battery immediately. Note
