The DEFreducing agent is required for reduc-
tion of engine emissions.
The operating permit is invalidated if you con-
tinue to use the vehicle without DEF. The legal
consequence of this is that the vehicle may no
longer be operated on public roads.
In the RangeRange menu window of the ß trip data
menu, you can display your vehicle's range
together with the currentfuel tank content
(Y page 75).
If the DEFlevel has dropped to approximately
10% of the tank capacity, acorresponding
event window appears in the on-board com-
puter. Refill the DEFtank in good time
(Y page 152).
If the yellow event window is ignored and the
DEFlevel drops further to approximately 2.5%,
engine power output may be reduced.
When the DEFtank has run dry, the event is
stored and is signaled by the ; indicator
lamp when starting the engine as an emission-
relevant fault (Y page 70). Additionally,
speed may be limited to approximately
12 mph (20 km/h).
