WARNING
The electrolyte of the high-voltage battery is
poisonous and corrosive. Avoid contact with
the skin, eyes or clothing, e.g. in the even tof
an accident.
Immediately rinse electrolyte splashes off
thoroughly with plenty of clean water. Consult
a docto rimmediately.
! Exhaustive discharge caused by the
vehicle standing idle for lengthy periods
can damage the high-voltage battery.
If the vehicle is idle for lengthy periods, run
it for a few minutes once every six weeks
to charge up the high-voltage battery.
During the charging process, switch off all
electrical consumers, e.g. the automatic
climate control or the seat heating.
Yourv ehicle is equipped with two 12V
batteries and one high-voltage battery. The
high-voltage battery stores the energy for the
electric motor. The engine can be started
using the electric motor.
Have any work on the batteries carried out at
a qualified specialist workshop.
i Observe the safety information
(Y page 14) and information about the 12V battery (see the vehicle Operator's

X Bring the vehicle to a stop with the engine
running.
The engine powers the electric motor. The
electric motor operates as a generator. The
high-voltage battery is being charged.
i In the "Charging when stationary"
operating mode, the high-voltage battery
can be charged to a maximum of 70%. You
can monitor the condition of charge of the
high-voltage battery in the COMAND
display and in the multifunction display
(Y page 29). Charging the 12 V battery
i Observe the safety information and
