The ESC OFF Indicator Light and the ESC Indi-
cator Light come on momentarily each time the
ignition is placed in the ON/RUN or ACC/ON/
RUN position.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive.
This light will come on when the vehicle is in an
ESC event.

Engine Check/Malfunction Indicator
Warning Light (MIL)
The MIL is a part of an Onboard
Diagnostic system called OBD II that
monitors engine and automatic
transmission control systems. This
warning light will illuminate when the ignition is in
the ON/RUN position before engine start. If the
bulb does not come on when turning the ignition
switch from OFF to ON/RUN, have the condition
checked promptly.
Certain conditions, such as a loose or missing gas
cap, poor quality fuel, etc., may illuminate the light
after engine start. The vehicle should be serviced if
the light stays on through several typical driving
styles. In most situations, the vehicle will drive
normally and will not require towing.
When the engine is running, the MIL may flash to
alert serious conditions that could lead to
immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced
by an authorized dealer as soon as possible if this
occurs.
AdBlue® (UREA) Injection System Failure
Warning Light — If Equipped
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. Contact an authorized dealer as soon as
possible.
WARNING!
A malfunctioning catalytic converter, as refer-
enced above, can reach higher temperatures
than in normal operating conditions. This can
cause a fire if you drive slowly or park over flam-
mable substances such as dry plants, wood,
cardboard, etc. This could result in death or seri-
ous injury to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the vehicle
control system. It also could affect fuel economy
and driveability. If the MIL is flashing, severe cata-
lytic converter damage and power loss will soon
occur. Immediate service is required.
