WARNING
ARNING Risk of burns due torepeatedly
switching on the seat heating
Re peatedly switching on the seat heating can
cause the seat cushion and seat backrest pad-
ding tobecome very hot.
In particular, the health of persons with limited
te mp erature sensitivity or a limited ability to
re act tohigh temp eratures may be a.ected or
th ey may even su.er burn-like injuries. #
Do not repeatedly switch on the seat
heating. To
protect against overheating, the seat heating
may be temp orarily deactivated aTer it has been
switched on repeatedl y.
% This function is only available for plug-in
hy brids or vehicles with a 48-V on-board elec-
trical system.
The air inside theve hicle can be heated, ventila-
te d or cooled tothe set temp erature when the
ve hicle is par ked.
When theve hicle is connected topowe r supply
equipment, priority is given tocharging the 48 V
battery or the high-voltage battery toa speci/ed
minimum charge.
The running time of pre-entry climate control may
be reduced under thefo llowing conditions (vehi-
cles with a 48 V on-board electrical system):
R The vehicle is not connected topowe r supply
equipment.
R The 48 V battery is not fully charge d. The
running time of pre-entry climate control may
be reduced under thefo llowing conditions (plug-in
hy brid):
R The vehicle is not connected topowe r supply
equipment.
R The high-voltage battery is not fully charge d.
Wi th active pre-ent ryclimate cont rol,th ech arge
le ve l of the 48 V battery or the high-voltage bat-
te ry may be reduced, even if thech arging cable
connector is connected.
If present, seat ventilation is activated in cooling
and ventilation mode.
Depending on theve hicle's equipment, thefo llo w-

WARNING
ARNING Risk ofchemical burns and poi-
soning from damaged high-voltage battery
If th e housing of the high-voltage battery has
been damaged, electrolyte and gases may
leak out. #
Avoid contact with the skin, eyes or
clo thing. #
Immediate lyrinse electrolyte splashes

tion straight away. &

GER Risk of explosion from excessive
internal pressure of the high-voltage bat-
te ry
Flammable gas may escape and ignite in the
eve nt of a vehicle /re. #
Stop thech arging process immediately
in case of unusual odours, smoke or
burn mar ks. #
Leavethe danger zone immediatel y.
Secure the danger zone at a su1cient
distance. #
Call the /re brigade. The
hybrid system combines a combustion engine
with electric mo tors. In drive prog ram A, the
hy brid system selects the most suitable drive type
according tothe driving conditions and the dis-
ta nce.
Cha racteristics when theve hicle is at a standstill:
R The combustion engine is generally switched
o..
R Idle speed only occurs in cer tain instances.
Characteristics when starting theve hicle:
R Ifth e high-voltage battery is su1ciently
ch arge d, theve hicle can be star ted with the
electric drive without the combustion engine
(noiseless start). R
Ifth e high-voltage battery forth e electrical
drive is not su1ciently charge d or the operat-
ing temp erature of the combustion engine has
not been reached, theve hicle can start with
th e combustion engine.
% Depending on the system, it may happen that
ev en though the high-voltage battery is
ch arge d, electric mode has restric ted or no
av ailabilit y.Once the combustion engine has
been operated for long enough and ambient
conditions permit, electric mode is again
av ailable without restriction.
Charac teristics wi thmoderate po wer output
re qu ests:
R The combustion engine is switched o. as
oTen as possible during the journe y.
R The vehicle can, depending on the drive pro-
gr am selected and the state of charge , be
accelerated elect rically up tospeeds of
appr oximately 140 km/h. ATer that, the com-
bustion engine is switched on. 208 208
