It may indicate that the poly-V-belt has broken. Should 
this condition occur, the poly-V-belt must be replaced 
before continuing to operate the vehicle. Otherwise, the 
engine will overheat due to an inoperative water pump 
which may result in damage to the engine.
Do not continue to drive the vehicle with this message 
displayed.
Doing so could result in serious engine damage that is 
not covered by the Mercedes-Benz Limited Warranty.
