Catalytic Converter Cautions
Your MERCEDES-BENZ is equipped
with monolithic catalytic converters, an
important element in conjunction with
the 0 2-sensor to achieve substantial
control of the pollutants in the exhaust
emissions. Keep your vehicle in proper
operating condition by following our
recommended maintenance instruc­
tions as outlined in your maintenance
booklet.
Should any noticeable irregularities in
the engine operation occur, such as
misfiring of one or more cylinders, indi­
cated by audible signs (e. g. rough id­
ling engine), excessive unburned fuel
may reach the converter causing it to
overheat. Continued operation of your
vehicle can result in damage to the
converter.
For the same reason we caution
against:
• Misuse or abuse of your vehicle
engine
• Refueling with leaded gasoline
• Excessive idling with cold engine
• Push or tow starting your vehicle
with hot engine.
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 in contact
with a hot exhaust system, as these
materials could be ignited.
We urge your cooperation by follow ­
ing the above instructions to achieve
cleaner air.
