Jeep Wrangler: Yellow Warning Lights / Electronic Stability Control (ESC) Active Warning Light — If Equipped
This warning light will indicate
when
the Electronic Stability Control system
is Active. The ESC Indicator Light in
the instrument cluster will come on
when the ignition is placed in the ON/RUN or

system. If this warning light remains on after
several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds
greater than 30 mph (48 km/h), see an
authorized dealer as soon as possible to have
the problem diagnosed and corrected.
