Pro. Otherwise risks may not be detec-
ted.
* NOTE High-voltage battery damage due to
leaving the vehicle idle for lengthy periods
of time
Lithium-ion batteries experience a natural self-
discharge.
Exhaustive discharging can therefore occur if
the vehicle is idle for several months. This can
damage the high-voltage battery.
To avoid damage, please observe the fol-
#
lowing recommendations when handling
the high-voltage battery.
* NOTE Accelerated ageing of the high-volt-
age battery due to not observing the fol-
lowing recommendations
As a result of its basic characteristics, the
storage capacity of, and the amount of energy
available from, the high-voltage battery
decreases over the course of its life. As a
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.
F243 0059 02
Driving and parking 245
* NOTE Damage to the drive system when
charging the high-voltage battery at
extreme altitudes
The drive system may be damaged if the high-
voltage battery is charged at elevations
greater than 4,000 m above sea level.
It may then no longer be possible to continue
the journey.
Avoid charging processes at extreme
#
altitudes.
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 %.
Rapid-charge the high-voltage battery with
R
direct current (Mode 4) only when required.
Charge the high-voltage battery on average up
R
to a charge status of 80 %. From a charge sta-
tus of 80 % the charge time increases signifi-
cantly.
