Possible cause/consequence
The poly-V-belt could be broken.
The cooling fan for the coolant is
malfunctioning.
Possible solution
Stop the vehicle in a safe location as soon as it is
safe to do so and immediately turn off the engine.
Check the poly-V-belt.
If it is broken:
Do not continue to drive. Otherwise the engine
will overheat due to an inoperative water pump
which may result in damage to the engine. Notify
an authorized Mercedes-Benz Center.
If it is intact:
Do not continue to drive the vehicle with this mes-
sage displayed. Doing so could result in serious
engine damage that is not covered by the
Mercedes-Benz Warranty.
Drive immediately to the nearest authorized Mer-
cedes-Benz Center.
Observe the coolant temperature display.
Have the fan replaced as soon as possible.
