WARNING Risk of c
hemical burns and poi-
soning from damaged high-voltage battery
If the housing of the high-voltage battery has
been damag
ed, electrolyte and gases may
leak out.
#
Avoid contact with the skin, eyes or
clo
thing.
#
Immediately rinse electrolyte splashes
o wit
h water and seek medical atten-
tion straight away.
&
DANGER Risk of r
e and explosion from
excessive internal pressure of the high-
voltage battery
In the event of a vehicle re, ammable gas
can escape and ignite.
#
Stop the charging process immediately
in case of unusual odour
s, smoke or
burn marks.
#
Leave the danger zone immediately.
Secur
e the danger zone at a sucient
distance.
#
Call the r
e service.
The hybrid system combines a combustion engine
wit
h an electric motor.
Characteristics when the vehicle is at a standstill:
R
The combustion engine is generally switched
o.
R
Idle speed occurs only in certain instances.
Characteristics when the vehicle is started:
R
If the high-voltage battery is suciently
charged, the vehicle can be started with the
electric drive system without the combustion
engine (noiseless start).
R
If the high-voltage battery for the electric drive
system is not suciently 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 that even
t
hough the high-voltage battery is charged,
electric mode has restricted or no availability.
Once the combustion engine has been oper-
ated for long enough, electric mode will be
again available without restriction.
Characteristics with moderate power output
r
equests:
R
The combustion engine is switched o as
oen as possible during the journey.
R
The vehicle can, depending on the drive pro-
gram selected and the state of charge of the
high-voltage battery, be accelerated electri-
cally up to speeds of approximately
140 km/h.
Characteristics with high power output requests:
R
The electric motor supports the combustion
engine (boost eect), e.g. when you pull away
or accelerate.
R
The high-voltage battery is discharging.
