on for further two seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.

Regenerative braking
Warning
In the case of extreme temperatures or
if the high voltage battery is almost fully
charged, the brake force of the engine
braking may be temporarily reduced. If
the braking force is not sufficient, the
driver has to be prepared to use the
brake pedal.
Warning
Depending on the engine braking force
the brake lights are illuminated.
BEV: Regenerative braking generates
electric energy resulting from engine
braking to charge the high voltage
battery.

Charging
GENERAL INFORMATION
Warning
Persons with a pacemaker should
consult a doctor for possible
precautions.
Charging the vehicle's high voltage
battery depends upon several factors:
● high voltage battery of the vehicle
●
internal onboard charger (OBC)
●
charging cable
●
external charging device
The charging cable connects the
vehicle with an external charging device
providing electric power. This may be
a domestic electrical outlet, a Green'Up
socket, a wall box or a public charging
station.
The high voltage battery is charged
with direct current (DC) only. When
charging the vehicle with alternating
current (AC), AC has to be converted
into DC. This is done by the vehicle's
onboard charger. The onboard charger is
available with 7.4kW (single-phase) and
11kW (3-phase).
If the vehicle is charged at a public DC
charging station, no DC conversion is
required. The high voltage battery can be
directly charged with DC provided by the
DC charging station.
The speed of charging the vehicle's
high voltage battery depends upon
the weakest element of the charging
chain. To achieve the maximum charging
speed, charging cable and charging
device have to be attuned to each other.
Note
Make sure that the charging cable used
fits to the vehicle's onboard charger.
