certified) in the Selective Catalytic Reduction (SCR) system.
The engine is not in compliance with emission regulations.
Do not mix the Diesel Exhaust Fluid (DEF) with other materials, this can cause damage to
the Selective Catalytic Reduction (SCR) system.
CAUTION: Decreased engine power because of a fault in the Selective Catalytic Reduction
(SCR) system.
When the Diesel Exhaust Fluid (DEF) quality sensor identifies a problem with the Diesel
Exhaust Fluid (DEF) quality, it send a CAN signal to the ECU. The ECU decreases the
engine power output.
Make sure that Diesel Exhaust Fluid (DEF) (DIN 70070 or ISO 22241 certified) is used in the
