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:
The fluid level is preset at the factory and does
not require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service tools...
Connect the positive (+) end of the jumper
cable to the remote positive (+) post of the
discharged vehicle.
Connect the opposite end of the positive (+)
jumper cable to the positive (+) post of the
booster battery.
Connect the negative end (-) of the jumper
cable to the negative (-) post of the booster
battery...
