Master display
NOTE: When this warning is active, the MIL appears, the engine power is
derated and eventually the vehicle speed is limited. After refilling the AdBlue
tank, this warning, the MIL, engine derate and speed limit are switched off.
A small quantity of AdBlue remains in the AdBlue tank even if the AdBlue
tank empty warning symbol is active.
NOTE: Next to the power derate and with a speed limit at the next warning,
driving without AdBlue irreparably damages the AdBlue doser.
This warning symbol is related to the EAS system and can give the
following text descriptions:
1. Speed limit at next standstill.
The speed limit is activated the next time the vehicle stops.
2. Speed limit 20 km/h (or 12 mph).
The vehicle speed is limited to 20 km/h or 12 mph.

This warning symbol is visible when the temperature of the coolant
exceeds the maximum permissible value. Check the following points:

Alternator warning
When the icon is red, the alternator charge voltage is incorrect.
If the charging voltage of the alternator rises above 31 V, this warning
symbol is shown. The battery voltage is then too high and the battery

possible.
If the symbol is still not extinguished, do not continue to drive
under any circumstances!
When the icon is yellow, there is a alternator failure.
