Characteristics with high power output requests:
The external noise of the sound generator is
perceptible in the vehicle interior at low
speeds and does not represent a malfunction.
If not all the vehicle conditions for electric
mode are met, the combustion engine will be
switched on.
Performance restrictions in electric mode are
possible as a result of the operating tempera-
ture of the high-voltage battery and drive sys-
tem, the ambient temperature and ageing of
the high-voltage battery.
In electric mode, the maximum power will not
be permanently available and may drop to
continuous output.
when the vehicle is driving both forwards and
in reverse.
This will help other road users, particularly
pedestrians and cyclists, to hear your vehicle
better.
When you drive at speeds above 20 km/h, the
acoustic vehicle alerting system will gradually
switch off.

The high-voltage battery is discharging.
Characteristics when the accelerator pedal is
released during the journey:
R
The electric motor is operated as an alternator
when in overrun mode and during braking.
R
The sound generator will be off when the vehi-
cle is stationary.
R
The high-voltage battery is charging.

Mercedes-AMG vehicles: the sound generator
of the acoustic vehicle alerting system also
generates stationary noise.

Notes on electric mode:
R
Vehicles with hybrid systems generate signifi-
cantly less noise when stationary and when
being driven than vehicles with combustion
engines.

Vehicles with diesel particulate filters: during
the regeneration of the diesel particulate fil-
ter, the drive programs will be unavailable or
restricted and the state of charge of the high-
voltage battery may change.

vehicle may not be heard by other road users
due to the significantly lower noise generated.
Notes on the acoustic vehicle alerting system:
For this reason, the vehicle is equipped with a
sound generator, which serves as an acoustic
vehicle alerting system (AVAS). This safety
device is prescribed by law.
