    • AUTO STOP position indicates that the vehicle is still able to move and the engine could restart, by an Auto Start, at any time.
    • OFF position indicates that either the vehicle was turned off or the engine has stalled.

When the engine is on, the tachometer indicates the engine's revolutions per minute.
