Neverto uch damaged components of
th e high-voltage on-board electrical sys-
te m. #
ATer an accident, do not touch any com-
ponents of the high-voltage on-board
electrical system. #
ATer an accident, ha vetheve hicle trans-
por tedawa y. #
Have the components of the high-voltage
on-board electrical system checked at a
qu ali/ed specialist workshop and
re placed if necessar y. The components of
the high-voltage on-board
electrical system are mar ked with yellow warning
stic kers. The cables of the high-voltage on-board
electrical system are orange.
Ve hicles with hybrid systems generate signi/-
cant lyless noise when stationary and when being
driven than vehicles with combustion engines.
When driving in elect ric mode, theve hicle may
not be heard by otherroad users due tothe signif-
icantly reduced noise generated. It is
forth is reason that theve hicle is equipped
with a sound generator, which ser ves as an acous-
tic vehicle alerting system (A VAS). Declar

to say it has no pr otection against harmful inter-
fe re nce, not even from the same type of stations,
and must not cause inter fere nce with systems

This product is permitted in accordance with the
procedure de/ned in Directive 242/2000 bythe
Brazilian telecommunications agency ANATEL and
meets the applicable tech nical requ irements.

WARNING
ARNING Risk of accident due toobjects
in the driver's foot we ll
Objects in the driver's foot we ll may impede
pedal tr avel or block a depressed pedal.
This jeopardises the operating and road saf ety
of theve hicle. #
Stow all objects in theve hicle securely
so that they cannot getinto the driver's
fo ot we ll. #
Always /t the 0oor mats securely and as
prescribed in order toensure that there
is alw ays su1cient room forth e pedals. #
Do not use loose 0oor mats and do not
place 0oor mats on top of one ano ther. 136 136

Forch arging stations without a preinstal-
led charging cable:
R For saf etyre asons, only use charging
cables that ha vebeen tested and
appro vedby the manufacturer for
ch arging the high-voltage battery in
an electric vehicle.
R Never use damaged charging cables.
R Do not extend thech arging cable.
R Do not use adap ters. #
Make sure toobser vethe saf ety in form a-
tion on thech arging station. Most
charging stations must be activated before
th ech arging process, e.g. using an RFID card.
Obser vethe on-site operator's inst ructions forthe
ch arging station.
The amount of ene rgy dispensed forth ech arging
process, shown bythech arging station, may be
higher than the amount of energy actually absor-
bed bythe high-voltage batter y.This is there sult
of di.erent le vels of charging losses and is descri-
bed as rech arge e1ciency. Charging losses occur,
fo rex ample, due toheat that builds up when ch
arging or from auxiliary consumers that are
switched on. Further information on rech arge e1-
ciency can be obtained at a quali/ed specialist
wo rkshop. N
