ment cluster.
The current condition of charge of the high-
voltage battery is shown as a percentage in
condition of charge display A. 100% corre-
sponds to the highest possible condition of
charge of the high-voltage battery. There are two further areas located to the left
and right of condition of charge display A:

Driving with the electric motor: when the
display reaches upper limit :, the com-
bustion engine is switched on. If the display is approaching upper limit :and you
remove your foot from the accelerator
pedal, the display empties again. The com- bustion engine is not switched on. At low
speeds, you can thereby control the elec-
tric operation usage so that you only drive
in electric mode.

If you rapidly depress the accelerator, the
electric motor supports the internal combus-
tion engine by providing additional torque.
The arrows for the energy flow are shown in
red.
Driving using the engine plus energy
recovery The engine powers the vehicle. The electric
motor is operating as a generator, e.g. in
overrun mode and when braking
(Y page 289). The kinetic energy of the vehi-
cle is converted into electrical energy. The
high-voltage battery is being charged.
The arrows for the energy flow are shown in
green.
Driving using the internal combustion
engine and charging the high-voltage bat-
tery The engine powers the vehicle. The engine
also powers the electric motor. The electric
motor operates as a generator. The high-volt-
age battery is being charged. The arrows for the energy flow are shown in
white.
Driving using the internal combustion
engine and discharging the high-voltage
battery The engine powers the vehicle. If the vehicle
is approaching a downhill gradient with a high
potential for energy recuperation, the condi-
tion of charge of the high-voltage battery is
intentionally kept low or intentionally
reduced.
The arrows for the energy flow are shown in
white.

The vehicle starts in electric mode without the
internal combustion engine (noiseless start).
The internal combustion engine starts only
after the power demanded by the driver
exceeds the available power that the electric motor can currently provide.
Noiseless start operation is dependent on the
outside temperature and the operating tem-
perature of the internal combustion engine. If
not all conditions for noiseless start operation are fulfilled, the vehicle starts with the inter-
nal combustion engine. X

X Depress the brake pedal.
X Observe the notes on starting the engine
(Y page 191).
X Start the vehicle (Y page 192).
