Notes on plug-in hybrids
▌Notes on plug-in hybrid operation
& 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 may
leak out.
Avoid contact with the skin, eyes or
#
clothing.
Immediately rinse electrolyte splashes
#
off with water and seek medical atten-
tion straight away.
& DANGER Risk of fire and explosion from
excessive internal pressure of the high-
voltage battery
In the event of a vehicle fire, flammable gas
can escape and ignite.
Stop the charging process immediately
#
in case of unusual odours, smoke or
burn marks.
Leave the danger zone immediately.
#
Secure the danger zone at a sufficient
distance.
Call the fire service.

The hybrid system combines a combustion engine
with an electric motor.
Characteristics when the vehicle is at a standstill:
The combustion engine is generally switched
R
off.
Idle speed occurs only in certain instances.
R
Characteristics when the vehicle is started:
If the high-voltage battery is sufficiently
R
charged, the vehicle can be started with the
electric drive system without the combustion
engine (noiseless start).
If the high-voltage battery for the electric drive
R
system is not sufficiently charged or the vehi-
cle conditions for a silent start are not met,

the vehicle will start with the combustion
engine.
% Depending on the system, it may be the case
that even though the high-voltage battery is
charged, electric mode has restricted or no
availability. Once the combustion engine has
been operated for long enough and ambient
conditions permit, electric mode will be avail-
able again without restriction.
Characteristics with moderate power output
requests:
The combustion engine is switched off as
R
often as possible during the journey.
The vehicle can, depending on the drive pro-
R
gram selected and the state of charge of the
high-voltage battery, be accelerated electri-
cally up to a speed of approximately
140 km/h.
Characteristics with high power output requests:
The electric motor supports the combustion
R
engine (boost effect), e.g. when you pull away
or accelerate.
The high-voltage battery is discharging.
