th
e maximum electrical range that can be ach-
ie ve dby theve hicle and its maximum elect ri-
cal output can be impaired.
The following factors could accelerate the age-
ing of the high-voltage batter y:
R a high le vel of charge , especially if the
ve hicle is idle for a lengt hyperiod of time
R leaving theve hicle idle for lengt hyperiods
at high ambient temp eratures #
Toavo id accelerated ageing, please
obser vethefo llowing recommendations
when handling the high-voltage batter y.Re
commendations when handling the high-voltage
batter y:
R If leaving theve hicle idle for lengt hyperiods,
park up theve hicle with a high- voltage battery
ch arge leve l between 30% and 50%. Do not
ke ep the high-voltage battery continuously
connected topowe r supply equipment.
R If leaving theve hicle idle for lengt hyperiods of
time avoid, if possible, high ambient temp era-
tures. R
Check the high-voltage battery's charge level
ev ery six weeks (/ page 326).
R Char gethe high-voltage battery if thech arge
le ve l is below 20%.
R Do not disconnect the 12 V battery even if the
ve hicle is leT idle for a lengt hyperiod. Other-
wise, the condition of theve hicle's high- volt-
age battery cannot be monitored.
Yo u can contribute toreducing theve hicle's
ene rgy consum ption in thefo llowing ways:
R An anticipatory driving style (/ page 176)
R Reduced use of electrical consumers
