In￿the￿diagram￿the￿relative￿and￿the￿absolute￿state￿of￿charge￿values￿(SOC￿values)￿of￿the￿high-voltage
battery￿are￿shown.￿The￿absolute￿values￿correspond￿to￿the￿actual￿state￿of￿charge￿of￿the￿high-voltage
battery.￿The￿relative￿SOC￿values￿are￿the￿values￿which￿are￿displayed￿to￿the￿driver￿in￿the￿instrument
cluster￿or￿in￿the￿central￿information￿display.￿In￿range￿"A"￿driving￿without￿power￿restriction￿and￿full
functionality￿of￿the￿convenience￿functions￿are￿available.￿If￿the￿SOC￿value￿of￿the￿high-voltage￿battery
approaches￿about￿5%,￿the￿Check￿Control￿messages￿for￿ranges￿between￿20 km￿and￿10 km￿are￿issued.
In￿range￿"B"￿the￿performance￿of￿the￿drive￿train￿is￿reduced￿due￿to￿the￿low￿state￿of￿charge￿of￿the￿high-
voltage￿battery.￿The￿heating￿and￿air-conditioning￿system￿is￿switched￿off￿here.
If￿the￿absolute￿SOC￿value￿falls￿below￿10%,￿driving￿the￿vehicle￿is￿no￿longer￿possible.￿The￿reserve￿of
10%￿is￿required￿to￿give￿the￿customer￿adequate￿time￿to￿charge￿the￿high-voltage￿battery￿and￿prevent
deep￿discharge.
The￿driver￿has￿the￿option￿to￿extend￿the￿range￿by￿activating￿ECO￿PRO￿or￿ECO￿PRO￿+￿mode.￿Here￿the
power￿of￿some￿electrical￿consumers￿is￿reduced￿or￿the￿consumers￿are￿switched￿off￿completely.￿In￿ECO
PRO￿mode￿the￿maximum￿speed￿is￿130 km/h￿(can￿be￿adjusted￿in￿ECO￿PRO￿menu￿from￿80 km/h￿to
130 km/h).￿In￿ECO￿PRO￿+￿mode￿the￿maximum￿driving￿speed￿is￿restricted￿to￿90 km/h.
