Your Mercury MerCruiser power package may be equipped with an Audio Warning System.
The audio warning system alarm will sound if one of the following occur:
1
Engine Oil Pressure Too Low
2
Engine Temperature Too Hot
3
Drive Oil Level Too Low
4
Engine Guardian Activated (Refer to Engine Guardian.)
NOTE: To test the system: Turn the ignition switch to the ON position without cranking the engine. The alarm
will sound if the system is working correctly.
Avoid engine damage. Do not operate engine once the alarm has sounded EXCEPT TO AVOID A

When the alarm sounds with the engine running, stop engine immediately. Investigate cause and correct it, if
possible. If cause cannot be determined, consult your Authorized Mercury MerCruiser Dealer.
