WARNING Risk of f
atal injury due to expo-
sure to extreme heat or cold in the vehicle
If persons, particularly children, are subjected
t
o prolonged exposure to intense heat or cold,
there is a risk of severe injury or even death. 
Never leave persons, particularly chil-
dr
en, unattended in the vehicle. &
WARNING Risk of bur
ns due to repeatedly
switching on the seat heating
Repeatedly switching on the seat heating can
cause t
he seat cushion and seat backrest pad-
ding to become very hot.
In particular, the health of persons with limited
temperature sensitivity or a limited ability to react to high temperatures may be
aMect
ed or
they may even suMer burn-like injuries. 
Do not repeatedly switch on the seat
heating. To protect against overheating, the seat heating
ma

y be temporarily deactivated aser it has been
switched on repeatedly.
% This function is available only for plug-in
h

ybrids or vehicles with a 48-V on-board elec-
trical system.
The air inside the vehicle can be heated, ventila-
t
ed or cooled to the set temperature when the
vehicle is parked.
When the vehicle is connected to power supply
equipment, priority will be given to charging the
48 V battery or the high-voltage battery to a
speciNed minimum charge.
The running time of pre-entry climate control may
be reduced in the following circumstances (vehi-
cles with a 48 V on-board electrical system):

The running time of pre-entry climate control may
be reduced in the following circumstances (plug-in

= The vehicle is not connected to power supply
equipment.
= The high-voltage battery is not fully charged.
With active pre-entry climate control, the charge
level of the 48 V battery or the high-voltage bat-
tery may be reduced, even if the charging cable
connector is connected.
If present, seat ventilation will be activated in
cooling and ventilation modes.
Depending on the vehicle's equipment, the follow-
ing functions will be activated in heating mode, if
available:
= Seat heating

DANGER Risk of f
atal injury due to poison-
ous exhaust gases
If the tailpipe is blocked or suPcient v
entila-
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter the vehi-
cle. This is the case in enclosed spaces or if
the vehicle gets stuck in snow, for example. 
Always switch the stationary heater oM in
enclosed spaces wit
hout an air extrac-
tion system, e.g. in garages. 
Keep the tailpipe and the area around
t

he vehicle free from snow when the
vehicle or the auxiliary heating is run-
ning. 
Open a door or a roof hatch on the wind-
w

ard side of the vehicle to ensure an
adequate supply of fresh air. &
WARNING Risk of Nr
e due to hot station-
ary heater components and exhaust gases
Flammable materials such as leaves, grass or
twigs ma
y ignite. 
When the stationary heater is switched
on, mak

e sure that:
= hot vehicle parts do not come into
contact with Oammable materials.
= the exhaust gas can Oow out of the
stationary heater exhaust pipe unhin-
dered.
= the exhaust gas does not come into

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
oM wit

h water and seek medical atten-
tion straight away. &
DANGER Risk of Nr
e and explosion from
excessive internal pressure of the high-
voltage battery
In the event of a vehicle Nr
e, Oammable 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 suPcient
distance. 
Call the Nr
e service. The hybrid system combines a combustion engine
wit
h an electric motor.
Characteristics when the vehicle is at a standstill: = The combustion engine is generally switched
oM.
= Idle speed occurs only in certain instances.
Characteristics when the vehicle is started: = If the high-voltage battery is suPciently
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
system is not suPciently 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:
= The combustion engine is switched oM as
osen as possible during the journey.
= 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:
= The electric motor supports the combustion
engine (boost eMect), e.g. when you pull away
or accelerate.
= The high-voltage battery is discharging. Driving and parking
