Index Explanation
A Range�in�which�driving�without�restrictions�is�possible
B Range�in�which�driving�with�restricted�drive�power�takes�place
C Range�in�which�driving�is�not�possible
1 Calculated�state�of�charge�of�the�high-voltage�battery�(State�of�Charge�=�SOC)
2 Warning�for�range�of�20 km
3 Warning�for�range�of�10 km
4 Warning�for�range�of�less�than�1 km
5 Axis�for�relative�SOC�values
6 Axis�for�absolute�SOC�values
7 SOC�of�the�high-voltage�battery�0%�absolute
8 SOC�of�the�high-voltage�battery�10%�absolute,�or�0%�relative
9 SOC�of�the�high-voltage�battery�14.2%�absolute,�or�4.9%�relative
10 SOC�of�the�high-voltage�battery�100%�relative
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.
