AdBlue® service indicator
For BlueTEC vehicles only.
The BlueTEC exhaust gas aftertreatment must be operated with the reducing agent AdBlue®
in order for it to function correctly. AdBlue® is topped up as part of the service.
Under normal operating conditions, a full tank of AdBlue® should last until the next
service due date.
Depending on how and where the vehicle is used, there may be an increase in the AdBlue®consumption,
resulting in the next service due date being brought forward.
Certain display messages show that AdBlue® must be topped up, e.g.
Refill AdBlue at workshop See Owner’s Manual
Refill AdBlue at workshop No start in .. km
A warning signal also sounds.
