Yellow Telltale Light What It Means
Engine Check/Malfunction Indicator Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic System called OBD II that monitors
engine and automatic transmission control systems. The light will illuminate when the ignition is in the ON/RUN position be-
fore 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, 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 se-
vere catalytic converter damage. The vehicle should be serviced as soon as possible if this occurs.
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
flammable substances such as dry plants,
wood, cardboard, etc. This could result in
death or serious injury to the driver, occu-
pants or others.
CAUTION!
Prolonged driving with the Malfunction Indi-
cator Light (MIL) on could cause damage to
the engine 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.
