Characteristics with high power output requests:
The electric motors support the combustion

engine (boost e ect), e.g. when pulling away
or accelerating.
The high-voltage battery is discharging.

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

In drive program Î, the vehicle drives
purely electrically, in drive programs C,
and B the combustion engine is always on
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 when
driving and when at a standstill.
It is for this reason that the vehicle is equip-
ped with a sound generator, which serves as
an acoustic vehicle alerting system (AVAS).
If not all of the vehicle conditions for electric
R
mode are met, then the combustion engine is
switched on.
Notes on the acoustic vehicle alerting system:
The sound generator generates a stationary
R
noise and, up to a speed of about 60 km/h,
speed-dependent vehicle noise emissions.
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
acoustic vehicle alerting system gradually
switches the vehicle noise emissions o .

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.
