Possible cause
The poly-V-belt could be broken.
The cooling fan for the coolant is
malfunctioning.
Suggested solution
Stop immediately and 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 message displayed. Doing so
could result in serious engine damage
that is not covered by the
Mercedes-Benz Limited Warranty.
Observe the coolant temperature
display.
Have the fan replaced as soon as
possible.
