The system warns of low AdBlue levels
in four steps with post-warning
indications as shown.
The texts and system reactions are as
follows:
1. 'AdBlue level low'.
To avoid further warnings, refill the AdBlue tank.
2. 'AdBlue level very low'.
The warning indicator at the AdBlue gauge changes colour to yellow.
To avoid further warnings, refill the AdBlue tank.
3. 'AdBlue level too low'.
The 'General' warning indicator comes on, and the engine power is reduced after a
vehicle standstill.
NOTE: Next to the power derate and with a speed limit at the next
warning, driving without AdBlue irreparably damages the AdBlue doser.
To avoid further warnings and reset the engine power derate, refill the AdBlue tank.
4. 'AdBlue tank empty'.
In addition to the 'General' warning indicator, the 'MIL' warning indicator comes on,
and, at the next key cycle, the vehicle speed limit is applied.
If there is no key cycle for a period of eight hours, a warning is displayed. This
warning informs the driver that the vehicle speed is limited starting at the next
vehicle standstill.
To avoid further warnings and reset the vehicle speed limit, refill the AdBlue tank.
The system also issues a post-warning indication for:
