Charging the high-voltage battery
when stationary (hybrid vehicles)
Only PLUG-IN HYBRID vehicles are equipped
with a high-voltage battery. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
! Only charge the high-voltage battery in the
"Charging when stationary" mode. Do not
connect a battery charger to the high-voltage battery. Otherwise, the vehicle's high-voltage
electrical system could be damaged.
X Stop the vehicle if the internal combustion
engine is running.
The internal combustion engine drives the
electric motor. The electric motor is operating
as an alternator. The high-voltage battery is
charging.
If the high-voltage battery is too heavily dis-
charged, recharge the high-voltage battery to at least 60% of its capacity. In the "Charging when
stationary" operating mode, you can observe
the charge status of the high-voltage battery up to a maximum of 70% in the COMAND display
and in the multifunction display (Y page 264).396
