Catalytic Converter - Chevrolet Tavera Owner's Manual

Catalytic Converter

The catalytic converter reduces the amount of harmful substances in the exhaust
gas.
The catalytic converter requires the use of ultra low sulfur diesel only. Usage of
high sulfur diesel will damage the converter. Under Normal operating conditions,
the converter will not require maintenance. However, it is important to keep the
engine properly tuned to ensure proper operation and prevent possible converter
damage.
In the event of misfiring, uneven engine running, a reduction in engine
performance or other unusual problem, have the cause of the fault rectified by a
CHEVROLET retailer as soon as possible. In an emergency, driving can be
continued for a short period, keeping vehicle speed and engine speed low.
CAUTION
Damage to the converter can result if your vehicle is not kept in proper operating
condition. In the event of engine malfunction, particularly involving engine misfire
or loss of performance, have your vehicle serviced promptly. Continued operation
of your vehicle with a severe malfunction could cause the converter to overheat,
resulting in possible damage to the converter and vehicle.
Unburnt fuel will overheat and damage the catalytic converter. Therefore avoid
excessive use of starter, running the fuel tank dry and starting the engine by
pushing or towing.
