Yellow TelltaleLight What It Means
Engine Check/Malfunction Indicator Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic Sys-
tem called OBD II that monitors engine and automatic transmission control systems. The light
will illuminate when the ignition is in the ON 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, 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
as soon as possible if this occurs.
