the engine has reached its overrevving 
range. Shift up to the next gear before 
the engine has reached its overrevving 
range. Make absolutely certain that the 
engine speed does not reach the red 
marking on the tachometer 
(page 24). Otherwise the engine 
could be damaged which is not covered 
by the Mercedes-Benz Limited
