Re
commendations when handling the high-voltage
batter y:
R If leaving theve hicle idle for lengt hyperiods,
park up theve hicle with a high- voltage battery
ch arge leve l between 25% and 30%. Do not
ke ep the high-voltage battery continuously
connected topowe r supply equipment.
R If leaving theve hicle idle for lengt hyperiods of
time avoid, if possible, high ambient temp era-
tures.
R Check the high-voltage battery's charge level
ev ery six weeks (/ page 201).
R Char gethe high-voltage battery if thech arge
le ve l is below 15%.
R Ifth e high-voltage battery is only used with at
low charge leve ls, fully charge the high-voltage
battery every six months.
R Do not disconnect the 12 V battery even if the
ve hicle is leT idle for a lengt hyperiod. Other-
wise, the condition of theve hicle's high- volt-
age battery cannot be monitored. Char

The high-voltage battery will be charge dby recu-
peration while you are driving. The electric mo tor
ser ves as an alternator when in overrun mode and
during braking.
Yo u ha vethefo llowing options tocharge while
stationar y:
R Ata mains soc ket (mode 2)

Obser vethe di.erent grid requ irements of your
cur rent location when charging. Only use charging
cables which conform tothegr id requiremen ts.
Consult a quali/ed elect rician or your local grid
operator if you ha veany questions.
It is recommended that youch arge the high-volt-
age battery at a wallbox or charging station due to
