The charging process uses high voltage.
If th ech arging cable, theve hicle soc ket or

re cei vean electric shoc k. #
Only use an undamaged charging cable. #
Avoid mechanical damage such as
crushing, abrading or driving over the

TEProtecting theve hicle from voltage
sur ges in the mains supply The
vehicle is equipped with an electrical
fuse forvo ltage sur ges in the mains suppl y.
This electrical fuse may be blown during
se vere thunder storms, forex ample, and may
cause the building's circuit breaker totrip
and thech arging process tobe inter rupted.
These functions help toprotect theve hicle.
Af terth e building pr otection sy stem has
been switched on again, thech arging proc‐
ess resumes automatically.
Fo llowing an inter ruption in the po wer supp ly
in which the building's circuit breaker is not
