Jeep Wrangler: Yellow Warning Lights / AdBlue® (UREA) Injection System Failure Warning Light — If Equipped
This warning light will
illuminate along
with a dedicated message on the
display (if equipped) if an unknown
fluid not conforming with acceptable characteristics is inserted, or if an
average
consumption of AdBlue® (UREA) over 50% is
detected. Contact an authorized dealer as soon
as possible.
If the problem is not solved, a specific message
will appear on the Instrument Cluster Display
whenever a certain threshold is reached until it
will no longer be possible to start the engine.
When about 125 miles (200 km) are remaining
before the AdBlue® (UREA) tank is empty, a
continuous dedicated message will appear on
the instrument panel, accompanied by a chime.

transmission control systems. This
warning light will illuminate when the ignition is
in the ON/RUN position before engine start...
This
warning light will illuminate to
