Jeep Grand Cherokee 2012, Owner'S Manual, Page: 292 / 688

WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.
4. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If Equipped
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the
ON/RUN position. It should go out with the
engine running. If the “ESC Activation/Malfunction In-
dicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC
system. If this 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
your authorized dealer as soon as possible to have the
problem diagnosed and corrected.
NOTE:
•
The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on mo-
mentarily each time the ignition switch is turned to
ON/RUN.
•
Each time the ignition is turned to ON/RUN, the ESC
system will be ON, even if it was turned off previously.
•
The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
