Jeep Wrangler: Yellow Warning Lights / Service 4WD Warning Light — If Equipped
This
warning light will illuminate to
signal a fault with the 4WD system. If
the light stays on or comes on during
driving, it means that the 4WD system
is not functioning properly and that service is
required. We recommend you drive to the
nearest service center and have the vehicle
serviced immediately.
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...
Other information:
WARNING!
Do not open the high pressure fuel system
with the engine running. Engine operation
causes high fuel pressure. High pressure fuel
spray can cause serious injury or death.
Add a substantial amount of fuel to the
tank, approximately 2 to 5 gal (8L to 19L)...
NOTE:
Using a fuel filter that does not meet the manufacturer’s
filtration and water separating
requirements can severely impact fuel system
life and reliability. We recommend you use
Mopar® Fuel Filter. Must meet 3 micron rating.
CAUTION!
Diesel fuel will damage blacktop paving
surfaces...
