Catalytic Converter
Your MERCEDES-BENZ is equipped
with monolithic type catalytic
converters, an important element in
conjunction with the O
2
sensor to
achieve substantial control of the
pollutants in the exhaust emissions.
Keep your vehicle in proper operating
condition by following our re-
commended maintenance instructions
as outlined in your Maintenance
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.
Warning!
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.
