ARNI NGDanger tolife due toexposure
to extreme heat or cold in theve hicle
If people, particular lych ildren, are exposed to
ex treme temp eratures over an extended
period of time, there is a risk of serious injury
or danger tolife. #
Never lea vepersons, children in particu-
lar, unattended in theve hicle. &

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-
