Jeep Wrangler: VEHICLE MAINTENANCE / Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) sometimes known
simply by the name of its active component,
UREA—is a key component of Selective Catalytic
Reduction (SCR) systems, which help diesel
vehicles meet stringent emission regulations.
DEF is a liquid reducing agent that reacts with
engine exhaust in the presence of a catalyst to
convert smog-forming nitrogen oxides (NOx)
into harmless nitrogen and water vapor.
This engine meets all required diesel engine
emissions standards. To achieve these
emissions standards, your vehicle is equipped
with a state-of-the-art engine and exhaust
system...
WARNING!
Do not attempt to inspect an accessory
drive belt with vehicle running.
When working near the radiator cooling fan,
disconnect the fan motor lead...
