Certain systems of the engine serve to keep the toxic
components of the exhaust gases within permissible
limits required by law.
These systems, of course, will function properly only
when maintained strictly according to factory
specifications. Any adjustments on the engine should,
therefore, be carried out only by qualified Mercedes-
B e n z a ut ho r i z e d c e n te r te chn i c i a n s . E n g i n e a d j u st m e n t s
should not be altered in any way. Moreover, the
specified service jobs must be carried out regularly
according to Mercedes-Benz servicing requirements.
For details refer to the Service Booklet.
Wa r n i n g !
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon monoxide,
and inhaling it can cause unconsciousness and
lead to death.Do not run the engine in confined areas (such as a
garage) which are not properly ventilated. If you
think that exhaust gas fumes are entering the
vehicle while driving, have the cause determined
and corrected immediately. If you must drive under
these conditions, drive only with at least one
window fully open.
