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.
Caution!
To prevent damage to the catalytic converters, use only 
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, which could start a fire.
Wa r n i n g !
As with any vehicle, do not idle, park or operate 
this vehicle in areas where combustible 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.
