Immedia tely rinse su rfaces that come in

If DEF has already cr ystallized, clean using a
spon geand cold water. If
yo u open the DEF tank, small amounts of
ammonia vapor may be released. Do not inhale
any ammonia vapor that may be released. Fill the
DEF tank only in well-ventilated areas.
DEF consum ption and filling capacity
DEF consum ption
Like fuel consum ption, DEF consum ption is highly
dependent upon driving style and operating con‐
ditions. DEF consum ption is usually within a
ra nge of 0 and 10% of the fuel consum ption. If
necessar y,DEF mu stbe refilled in acco rdance
with the instructions when there fill message is
displa yed in the instrument clus ter.This may also
be necessary between the scheduled mainte‐
nance.

stgas af tertre atment
The vehicle must be operated with DEF if the
ex haust gas af tertre atment sy stem is tofunction
cor rectl y.
If yo u operate theve hicle without DEF or with
emissions-rele vant malfunctions, the legal MOT
appr oval is in validated. The vehicle could be pro‐
hibited from public road use byan of ficial ordi‐
nance.
It may be improper or punishable in some coun‐
tries tooperate a vehicle that uses no DEF or one
th at does not comply with the specifications of
th ese operating instructions.
Engine management monitors theex haust gas
af te rtre atment components for compliance with
emissions la wsand regulations. If you attem ptto
operate theve hicle without DEF, with diluted DEF
or with a dif fere nt reducing agent, this will be
de tected bythe engine management sy stem.
Other emissions- releva nt malfunctions, e.g.
me tering malfunctions or sensor er rors, are also
de tected and log ged. The engine management sy
stem subsequently
pr eve nts the engine being restar ted af ter issuing
a wa rning message.
