Malfunction Indicator Light
WARNING: This page is about a different car, the 2003 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
As a bulb and system check, the Malfunction Indicator Light (MIL) will illuminate when ignition switch is turned to RUN position and engine is not running. When engine is started, MIL should go out. If MIL does not go out, a malfunction has been detected in the computerized engine control system or MIL circuit is faulty. To access codes, see SELF-DIAGNOSTICS - 1.8L VIBE article.
