Depending on the temperature, the fan and bat-
tery cooling system may audibly switch on dur-
ing the charging process.
As soon as the charging process begins, you can
display the charging prediction on the
Settings
on-board computer menu. The charging predic-
tion is either the anticipated condition of charge
at the programed departure time or the time
when the high-voltage battery will be fully
charged (
Y
page 44).
The charging speed or charge time depends on
the power supply.
For short charge times, charge the vehicle:
R
at a wallbox (
Y
page 36)
R
at a charging station (
Y
page 36)
Always observe the local information.
Certified electric energy consumption levels can
only be reached by charging at a charging sta-
tion.
It may take longer to charge the high-voltage
battery in the following conditions:
R
at low outside temperatures
R
if the vehicle has been idle for an extended
period without charging the high-voltage bat-
tery
The high-voltage battery is fully charged when:
R
the condition of charge indicator in the energy
flow display of the on-board computer has
reached 100 % (

Overvoltage protection
!
Voltage surges in the mains supply can dam-
age the vehicle. The vehicle is therefore
equipped with a device which protects it from
voltage surges in the mains supply. This
device may be triggered during severe thun-
derstorms, for example, and may lead to the
building's fuse being tripped and an interrup-
tion in the power supply. These functions pro-
tect the vehicle. After the building fuse is
switched on again, the charging process
resumes automatically. Following an interrup-
tion in the power supply without the building's
fuse being tripped, it may take up to
10 minutes for charging to resume automat-
ically.
Switch on the building protection system again
after it has been triggered. Otherwise, the
charging process cannot be continued.

Pay attention to the important safety notes
(

page 29).
The vehicle socket is located in the rear bumper
on the right below the tail lamp.
The charge socket flap and the vehicle are cen-
trally locked or unlocked simultaneously.
