Electrolyte may escape if the glass in an auto-
matic anti-dazzle mir ror breaks.
The electrolyte is hazardous tohealth and cau-
ses ir rita tion. It must not come into contact
with your skin, eyes, respiratory or gans or
clo thing or be swallo wed. #
Ifyo u come into contact with electrolyte,
obser vethefo llowing:
R Immediate lyrinse the electrolyte
from your skin with water and seek
medical attention.
R If electrolyte comes into contact with
your eyes, immediately rinse them
th oroughly with clean water and seek
medical attention.
R Ifth e electrolyte is swallo wed, imme-
diately rinse your mouth out thor-
oughl y.Do not induce vomiting. Seek
medical attention immediatel y. R
Immediately change out of clo thing
which has been contaminated with
electrolyte.
R If an allergic reaction occurs, seek
medical attention immediatel y. The inside
rear-view mir ror and the outside mir ror
on the driver's side will automatically go into anti-
dazzle mode if light from a headlamp hits the sen-

to extreme heat or cold in theve hicle
If people, particular lych ildren, are exposed to

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
