1 This 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.

temperature gauge. See page 123

°

temperature above 120
°

engine damage which is not covered by the 
Mercedes-Benz Limited Warranty.

Warning!
Driving when your engine is badly overheated can 
cause some fluids which may have leaked into the 
engine compartment to catch fire. You could be 
seriously burned.
Steam from an overheated engine can cause serious 
burns and can occur just by opening the engine 
hood. Stay away from the engine if you see or hear 
steam coming from it.
Turn off the engine, get out of the vehicle and do 
not stand near the vehicle until it cools down.
