Possible cause
The poly-V-belt could be broken.
Possible solution
Stop the vehicle 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:
Restart the engine only after the message
disappears from the multifunction dis-
play. Doing so could result in serious en-
gine damage that is not covered by the
Mercedes-Benz Limited Warranty.
Observe the coolant temperature gauge
in the instrument cluster ( page 24).
Drive immediately to the nearest autho-
rized Mercedes-Benz Center. Adjust driv-
ing to be consistent with reduced braking
responsiveness.
