result, the maximum electrical range that can
be achieved by the vehicle is reduced and its
maximum electrical output can be impaired.
The following factors could accelerate the age-
ing of the high-voltage battery:
frequently fully charging (charge level
R
100%) the high-voltage battery, especially
when this process is not directly followed
by a journey
frequent rapid charging with direct current
R
(mode 4)
leaving the vehicle idle for lengthy periods
R
at high ambient temperatures
To avoid accelerated ageing, please
#
observe the following recommendations
when handling the high-voltage battery.
Recommendations when handling the high-voltage
battery:
Every six months, when the outside tempera-
R
ture is above 10°C, park the vehicle overnight
with a charge level below 20%.
Only charge the high-voltage battery with
R
direct current (mode 4) if necessary.
Charge the high-voltage battery on average to
R
a charge level of 80%. Beyond a charge level of
80%, the charging time is considerably pro-
longed.
If leaving the vehicle idle for lengthy periods,
R
park up the vehicle with a high-voltage battery
charge level between 30% and 50%. Do not
keep the high-voltage battery continuously
connected to power supply equipment.
If leaving the vehicle idle for lengthy periods of
R
time avoid, if possible, high ambient tempera-
tures.
Check the high-voltage battery's charge level
R
every six weeks ( page 303).
/
Charge the high-voltage battery if the charge
R
level is below 20%.
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.

cle sockets.
You can charge the high-voltage battery with
both alternating current (mode 2/3) and
direct current (mode 4).
