— Malfunction Indicator Light (MIL)

The Malfunction Indicator Light (MIL) is part of an onboard diagnostic system called OBD
II that monitors engine and automatic transmission control systems. The light will
illuminate when the key is in the ON/RUN position before engine start. If the bulb does not
come on when turning the key from OFF to ON/RUN, have the condition checked
promptly.
Certain conditions, poor fuel quality, etc., may illuminate the light after engine start. The
vehicle should be serviced if the light stays on through several of your typical driving
cycles. In most situations, the vehicle will drive normally and will not require towing.
A malfunctioning catalytic converter, as referenced above, can reach higher tempera-
tures 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.
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 catalytic converter damage and power loss will soon occur.
Immediate service is required.
— Electronic Stability Control (ESC) Activation/Malfunction Indicator Light
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 Indicator Light" comes on continu-
ously 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 momentarily 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.
WARNING!
CAUTION!
