ARNING 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
#
o with water and seek medical atten-
tion straight away.
& D D AN
ANGER GER Risk of explosion from excessive
internal pressure of the high-voltage bat-
tery
Flammable gas may escape and ignite in the
event of a vehicle re.
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 su cient
distance.
Call the re brigade.

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
o .
Idle speed only occurs in certain instances.
R
Characteristics when starting the vehicle:
If the high-voltage battery is su ciently
R
charged, the vehicle can be started with the
electric drive without the combustion engine
(noiseless start).
If the high-voltage battery for the electrical
R
drive is not su ciently charged or the operat-
ing temperature of the combustion engine has
not been reached, the vehicle can 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, electric mode
is again available without restriction.
%
To start the combustion engine, the high-volt-
age battery can be used as a starter battery.
Characteristics with moderate power output
requests:
The combustion engine is switched o as
R
o en as possible during the journey.
The vehicle can, depending on the drive pro-
R
gram selected and the battery charge level, be
accelerated electrically up to speeds of about
140 km/h.
Characteristics with high power output requests:
The electric motor supports the combustion
R
engine (boost e ect), e.g. when pulling away
or accelerating.
The high-voltage battery is discharging.
