Selective Catalytic Reduction System -> Selective Catalytic Reduction System Requirements for Your Ford Focus 4 Door 2023

Selective Catalytic Reduction System  
WHAT IS THE SELECTIVE  
WARNING: The AdBlue® must be  
refilled when low or replaced when  
contaminated or your vehicle speed  
becomes limited to 80 km/h (50 mph).  
In these conditions, drive with caution  
and immediately refill the AdBlue® tank.  
If the AdBlue® tank becomes empty or  
the fluid contaminated and it is not  
replaced, your vehicle becomes limited  
to engine idle only once stopped. In these  
conditions, be cautious where you stop  
your vehicle because you may not be  
able to drive long distances or maintain  
highway speeds until you refill or replace  
the fluid.  
CATALYTIC REDUCTION  
SYSTEM  
Selective catalytic reduction is an engine  
emission control system that reduces  
exhaust emission levels by injecting  
AdBlue® into the exhaust system.

immediately clean with soap and water.  
If you swallow any AdBlue®, drink plenty  
of water and immediately seek medical

any other liquid.  
Do not put AdBlue® in the vehicle fuel
