Suzuki Grand Vitara: Catalytic Converter
Catalytic Converter
The purpose of the catalytic converter is to minimize the amount of harmful pollutants in your vehicle’s exhaust. Use of leaded fuel in vehicles equipped with catalytic converters is prohibited by federal law, because lead deactivates the pollutantreducing components of the catalyst system. The converter is designed to last the life of the vehicle under normal usage and when unleaded fuel is used. No special maintenance is required on the converter. However, it is very important to keep the engine properly tuned. Engine misfiring, which can result from an improperly tuned engine, may cause overheating of the catalyst. This may result in permanent heat damage to the catalyst and other vehicle components.
CAUTION: To minimize the possibility of catalyst or other vehicle damage:
• Maintain the engine in the proper operating condition.
• In the event of an engine malfunction, particularly one involving engine misfire
or other apparent loss of performance, have the vehicle serviced promptly.
• Do not shut off the engine or interrupt the ignition when the transmission is
in gear and the vehicle is in motion.
• Do not try to start the engine by pushing or towing the vehicle or coasting down
a hill.
• Do not idle the engine with any spark plug wires disconnected or removed, such
as during diagnostic testing.
• Do not idle the vehicle for prolonged periods if idling seems rough or there are
other malfunctions.
• Do not allow the fuel tank to get near the empty level.
WARNING: Be careful where you
park and drive; the catalytic converter and other exhaust components can get very
hot. As with any vehicle, do not park or operate this vehicle in areas where combustible
materials such as dry grass or leaves can come in contact with a hot exhaust system.
