Mercedes-Benz E-Class Estate 2021, Owner'S Manual

Page: 167 / 533

Characteristics with high power output requests:
R
The electric motors support the combustion
engine (boost e ect), e.g. when pulling away
or accelerating.
R
The high-voltage battery is discharging.
Characteristics when releasing the accelerator
pedal during the journey:
R
The electric motor on the rear axle is operated
as a alternator when in overrun mode and dur-
ing braking.
R
The high-voltage battery is charging.

Notes on electric mode:
R
Vehicles with hybrid systems in electric mode
generate signi cantly less noise when station-
ary and when being driven than vehicles with
combustion engines.
R
When driving in electric mode the vehicle may
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).
R
If not all of the vehicle conditions for electric
mode are met, then the combustion engine is
switched on.
Notes on the acoustic vehicle alerting system:
R
The sound generator generates a stationary
noise and, up to a speed of about 30 km/h.
R
This helps other road users, particularly
pedestrians and cyclists, to hear your vehicle
better.
R
When driving at speeds above 20 km/h the
acoustic vehicle alerting system gradually
switches the vehicle noise emissions o .

DDAN 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.
