Characteristics when releasing the accelerator
pedal during the journey:
The electric motor is operated as a alternator
R
when in overrun mode and during braking.
The high-voltage battery is charging.

Notes on electric mode:
Vehicles with hybrid systems generate signi -
R
cantly less noise when stationary and when
being driven than vehicles with combustion
engines.
When driving in electric mode, the vehicle may
R
not be heard by other road users due to the
signi cantly reduced noise generated.
It is for this reason that the vehicle is equip-
ped with a sound generator, which serves as
an acoustic vehicle warning system (AVAS).
If not all of the vehicle conditions for electric
R
mode are met, then the combustion engine is
switched on.
%
V V ehicles wit ehicles with diesel par h diesel particulat ticulate e lt lter ers: s: During
the regeneration of the diesel particulate l-
ter, the drive programmes are not available or
are restricted and the battery charge level
may change.
Notes on the acoustic vehicle warning system:
The sound generator generates speed-depend-
R
ent vehicle noise emissions when driving
forward or backing up at a speed of up to
around 30 km/h.
This helps other road users, particularly
R
pedestrians and cyclists, to hear your vehicle
better.
When driving at speeds above 20 km/h The
R
vehicle acoustic warning system gradually
switches o .
The sound generator is o when the vehicle is
R
stationary.

ANGER GER Risk of death and re due to
modi ed and/or damaged components of
the high-voltage on-board electrical sys-
tem
The vehicle's high-voltage on-board electrical
system is under high voltage. If you modify
component parts in the vehicle's high-voltage
on-board electrical system or touch damaged
component parts, you may be electrocuted. In
addition, modi ed and/or damaged compo-
nents may cause a re.
In the event of an accident or impact to the
vehicle underbody, components of the high-
voltage electrical system may be damaged
although the damage is not visible.
Never make any modi cations to the
#
high-voltage on-board electrical system.
Do not switch on or use the vehicle if its
#
high-voltage on-board electrical system
components have been modi ed or dam-
aged.
