The poly-V-belt could be broken.
Possible solution
Stop the vehicle in a safe location and im-
mediately turn off the engine.
Check the poly-V-belt.
If it is broken:
Do not continue to drive. Otherwise the en-
gine will overheat due to an inoperative wa-
ter pump which may result in damage to the
engine. Notify an authorized Mercedes-Benz
Center.

Do not continue to drive the vehicle with
this message displayed. Doing so could re-
sult in serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Observe the coolant temperature indicator
in the instrument cluster ( page 27).
Drive immediately to the nearest authorized
Mercedes-Benz Center.
