Maintenance

Emission control
Certain systems of the engine serve to keep
the toxic components of the exhaust gases
within permissible limits required by law.
These systems 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-Benz Center author-
ized technicians.
Engine adjustments should not be altered in
any way. Moreover, the specified service pro-
cedures must be carried out regularly accord-
ing to Mercedes-Benz servicing require-
ments. For details refer to the Maintenance
Booklet.
G
Warning!
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains car-
bon monoxide (CO), and inhaling it can
cause unconsciousness and possible
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 driv-
ing, have the cause determined and cor-
rected immediately. If you must drive under
these conditions, drive only with at least
one window fully open at all times.
Maintenance
Notes
The Maintenance System in your vehicle
tracks distance driven and the time elapsed
since the last maintenance service, calcu-
lates other maintenance service work
required, and calls for the next maintenance
service accordingly.
We strongly recommend that you have your
vehicle serviced at an authorized Mercedes-
Benz Center, in accordance with the Mainte-
nance Booklet at the times called for by the
maintenance service indicator.
i
Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times/mileage (kilometers) will
result in vehicle damage not covered by the
Mercedes-Benz Limited Warranty.
