The catalytic converter provides exhaust gas after-treatment to help reduce pollutants in the exhaust
gas. To help ensure long service life of the exhaust system and gasoline engine catalytic converter:
x Only use unleaded fuel.
x Never completely empty the fuel tank.
x Do not exceed the correct oil level, Engine oil.
x Do not tow the vehicle to start it, but use a jump-start instead, Jump-starting.
If you experience misfires, loss of power or the engine is not running smoothly while driving, reduce
speed immediately and have the vehicle checked by an authorized Volkswagen dealer or authorized
Volkswagen Service Facility. Otherwise, gasoline could reach the exhaust system and get into the
atmosphere. The catalytic converter could also be damaged by overheating!
Under certain engine conditions, you may smell a sulfur odor. This is not an indication of a
malfunctioning emission control system. This depends upon the sulfur content of the diesel fuel.
Diesel particulate filter
¤Please first read and note the introductory information and heed the WARNINGS
The diesel particulate filter helps take soot particles out of the exhaust. The soot particles are collected
and periodically burned in the filter at high temperatures (regeneration). The resulting heat can cause
the temperature inside the engine compartment to increase.
Regeneration can create noises, slight smells, and, regardless of the outside temperature, cause the
radiator fan to start – even after the engine has been turned off.
Volkswagen recommends frequently driving longer distances to help clean the filter. On vehicles with
automatic transmissions, the engine speed may also increase slightly. The indicator light
÷
will not
come on.
To lengthen the life of the exhaust system and the diesel particulate filter:
x Use only Ultra Low Sulfur Diesel (ULSD) fuel No. 2, Fuel.
x Never refuel with gasoline or fuel oil or biodiesel that does not comply with the special
requirements for diesel fuel, Diesel fuel.
x Never drive until the fuel tank is completely empty.
x Do not exceed the correct oil level, Engine oil.
x Do not tow the vehicle to start, but use a jump-start instead, Jump-starting.
On vehicles with automatic transmissions, increase the engine speed slightly while driving to
automatically start cleaning the diesel particulate filter. This helps to minimize clogging of the filter. The
indicator light
÷
will not come on.
WARNING
Obey all applicable legal requirements when cleaning the diesel particulate filter.
x Clean the diesel particulate filter as recommended only when visibility, weather, road, and
traffic conditions permit.
x Do not put others at risk.
Under certain engine conditions, you may smell a sulfur odor. This is not an indication of a
