Selective catalytic reduction*
(AdBlue)
Intr
oduction
In vehicles with “Selective Catalytic Reduc-
tion”, a speci
al urea solution (AdBlue) is in-
jected into the exhaust gas system in front of
the catalytic converter to reduce nitrogen ox-
ide emissions.
The consumption of AdBlue depends on indi-
vidual driving style, the temperature at which
the system operates and the outside temper-
ature where the vehicle is driven.
AdBlue is kept in an independent tank in the
vehicle and should be refilled at an official
supplier. The AdBlue tank holds about 17 li-
tres.
The AdBlue fill level must be checked when
the vehicle is being serviced.
WARNING
If the AdBlue fill level is too low, the vehicle
may
not restart after switching the ignition
off. The emergency start or jump start will not
be possible either!
●
Top up with AdBlue at the latest 1,000 km
or 600 miles before it runs out.
●
Do not allow the AdBlue to run too low.
WARNING
AdBlue is an irritant, corrosive liquid that can
cause injurie
s if it touches the skin, eyes or
respiratory organs.
●
If AdBlue get in contact with eyes and skin,
rinse for at least 15 minutes with plenty of
water and seek medical help.
●
If the AdBlue is swallowed, wash your
mouth with plenty of water for at least 15 mi-
nutes. Do not try to provoke vomiting unless
recommended by a Doctor. Seek medical ad-
vice immediately.
CAUTION
AdBlue damages surfaces such as painted ve-
hicle p
arts, plastic, items of clothing and car-
pets. Spilt AdBlue should be removed as
quickly as possible using a damp cloth and
plenty of cold water.
●
If the AdBlue has crystallised, remove with
warm water and a sponge.
