Do not disconnect the 12 V battery even if the
R
vehicle is left idle for a lengthy period. Other-
wise, the condition of the vehicle's high-volt-
age battery cannot be monitored.
You can contribute to reducing the vehicle's
energy consumption in the following ways:
An anticipatory driving style (

When using a CCS (Combined Charging Sys-
tem) charging cable to charge with direct cur-
rent, both areas of the vehicle socket are cov-
ered by the charging cable connector.
Charging options for the high-voltage battery
(mode 2, 3 or 4):
Charging through recuperation while the vehi-
R
cle is in motion
Charging with alternating current when sta-

tionary:
at a mains socket (mode 2)

Depending on the country-specific vehicle equip-
ment and your vehicle's charging cable, single
phase AC charging is also possible.
Observe the different grid requirements of your
current location when charging. Use only charging
cables that conform to the grid requirements.
Consult a qualified electrician or your local grid
operator if you have any questions.
It is recommended that you charge the high-volt-
age battery at a wallbox or charging station due to
the improved charging performance and better
charging efficiency offered.
