Mercedes Benz 2004 c 320 Manual De Usuario

Your Mercedes-Benz is equipped with 
monolithic-type catalytic converters, an 
important element in conjunction with the 
oxygen sensors to achieve substantial 
control of the pollutants in the exhaust 
emissions. Keep your vehicle in proper 
operating condition by following our 
recommended maintenance instructions 
as outlined in your Service Booklet.

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-Benz Center authorized techni-
cians. Engine adjustments 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.

!

To prevent damage to the catalytic 
converters, only use premium unleaded 
gasoline in this vehicle.

Any noticeable irregularities in engine 
operation should be repaired promptly. 
Otherwise, excessive unburned fuel 
may reach the catalytic converter, 
causing it to overheat and start a fire.

G

As with any vehicle, do not idle, park or 
operate this vehicle in areas where combus-
tible materials such as grass, hay or leaves 
can come into contact with the hot exhaust 
system, as these materials could be ignited 
and cause a vehicle fire.
