Selective Catalytic Reduction* (Adblue) - Seat Alhambra Owner's Manual

Selective catalytic reduc-
tion* (AdBlue)
Introduction
In vehicles with "Selective Catalytic Reduc-
tion", a special urea solution (AdBlue) is injec-
ted into the exhaust gas system in front of the
catalytic converter to reduce nitrogen oxide
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 approximate-
ly 17 litres.
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.
●
Checking and refilling levels
WARNING
AdBlue is an irritant, corrosive liquid that
can cause injuries 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 plen-
ty of water and seek medical help.
If the AdBlue is swallowed, wash your
●
mouth with plenty of water for at least 15
minutes. Do not try to provoke vomiting un-
less recommended by a Doctor. Seek med-
ical advice immediately.
CAUTION
AdBlue damages surfaces such as painted
vehicle parts, plastic, items of clothing and
carpets. 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.
