Notes on electric mode
&WARNING Risk of chemical burns and poi-
soning from damaged high-voltage battery
If the housing of the high-voltage battery has been damaged, electrolyte and gases mayleak out.
Avoid contact with the skin, eyes or
clothing.Immediately rinse electrolyte splashes
oM with water and seek medical atten-
tion straight away.&DANGER Risk of Nre and explosion from
excessive internal pressure of the high-
voltage battery
In the event of a vehicle Nre, Oammable gas
can escape and ignite.
If there is an unusual smell, smoke or
burn marks, stop the charging process
immediately.Leave the danger zone immediately.
Secure the danger area at a suPcient
distance.Call the Nre service.Observe the following notes on vehicle noise
emissions and the acoustic vehicle alerting sys-tem:
= The vehicle is equipped with an all-electric
drive system and produces considerably lower
stationary and vehicle noise emissions than a vehicle with a combustion engine.
For this reason the vehicle is equipped with a sound generator, which serves as an acousticvehicle alerting system (AVAS). This safety
device is prescribed by law.
The external noise of the sound generator is
perceptible in the vehicle interior when the
vehicle is stationary and at low speeds and
does not represent a malfunction.
= The sound generator generates stationary
noise and speed-dependent vehicle noise
emissions up to a speed of around 25 mph
(30 km/h).
This helps other road users, particularly
pedestrians and cyclists, to hear your vehicle
better.186Driving and parking

=When you drive at speeds above 20 mph
(20 km/h) the acoustic vehicle alerting sys-
tem will gradually switch oM.
= Despite the sound generator, the vehicle still
may not be heard by other road users. Adapt your driving style accordingly.
