Jeep Wrangler: Yellow Warning Lights / Service 4WD Warning Light — If Equipped

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

average
consumption of AdBlue® (UREA) over 50% is
detected...
