    Lightening bolt is the malfunction light

    X is the shut down light.  Shutdown light comes on for something that can damage the engine.  Coolant temp, coolant level, oil pressure, things like this.  


    Check your coolant level.

    On most all Macks (except the 2010+) when both lights are on it's low coolant (or bad low coolant sensor)
