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 electric motors. In drive program A, the
hybrid system selects the most suitable drive type
according to the driving conditions and the dis-
tance.
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 happen 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 is again
available 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, be
accelerated electrically up to speeds of
approximately 130 km/h. After that, the com-
bustion engine is switched on.
