ses over the course of its life. Due to this, both
the maximum electrical range that can be ach-
ieved by the vehicle and its maximum electri-
cal output can be impaired.
The following factors could accelerate the age-
ing of the high-voltage battery:
a high level of charge, especially if the
R
vehicle is idle for a lengthy period of time
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:
Only charge the high-voltage battery with
R
direct current (mode 4) if necessary.
If leaving the vehicle idle for lengthy periods,
R
park up the vehicle with a high-voltage battery
charge level between 25% and 30%. 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 231).
/
Charge the high-voltage battery if the charge
R
level is below 15%.
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.
