WARNING
If the charge current draw via a mains socket
is too high during the charging process, the
external mains supply may overheat. There is
a risk of fire.
Before charging, check the maximum permis-
sible charge current available at the location.
If necessary, contact a qualified specialist
company for assistance.
Adjust your vehicle's settings, if necessary.
