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...
Other information:
The transmission must be in PARK or
NEUTRAL.
Press and hold the brake pedal while
pushing the ENGINE START/STOP button
once.
The system takes over and attempts to start
the vehicle. If the vehicle fails to start, the
starter will disengage automatically after
10 seconds...
Vehicle body care requirements vary according
to geographic locations and usage. Chemicals
that make roads passable in snow and ice and
those that are sprayed on trees and road
surfaces during other seasons are highly
corrosive to the metal in your vehicle...
