Selective Catalytic Reduction (SCR) exhaust treatment - Overview

Diesel Exhaust Fluid (DEF)/AdBlue® instrumentation warning
ATTENTION: The fuel system, exhaust after-treatment system, and engine on your machine are designed and built
to government emissions standards. Tampering by dealers, customers, operators, and users is strictly prohibited by
law. Failure to comply could result in government fines, rework charges, invalid warranty, legal action, and possible
confiscation of the machine until rework to original condition is completed. Engine service and/or repairs must be
done by a certified technician only!
Your NEW HOLLAND CONSTRUCTION machine is equipped with a warning system to inform the operator of the
DEF/AdBlue® level, system malfunctions, and engine power loss that may result from the SCR system for reducing
exhaust emissions.

Stop engine light
During normal operation of your NEW HOLLAND CON-
STRUCTION machine, the instrument cluster displays the
DEF/AdBlue® fluid level (1) at all times.
Warning lights and indicators will be illuminated with a
warning on the visual display. The display changes au-
tomatically to allow the operator to view the warning indi-
cator and display message.
NOTICE: Avoid key-cycles when an active Selective Cat-
alytic Reduction (SCR) exhaust treatment error occurs.
Key cycles with active errors, will quickly increase the
de-rate severity. Once the maximum de-rate level has
been reached, the unit will be forced to low idle only. Best
practice is to move the machine to an area that is easily
accessible for service or for loading onto a transport vehi-
cle.
