Under normal operating conditions, the catalytic con-

verter will not require maintenance. However, it is im-

portant to keep the engine properly tuned to assure

proper catalyst operation and prevent possible catalyst

damage.
NOTE:

Intentional tampering with emissions control

systems can result in civil penalties being assessed

against you.
In unusual situations involving grossly malfunctioning

engine operation, a scorching odor may suggest severe

and abnormal catalyst overheating. If this occurs, stop

the vehicle, turn off the engine and allow it to cool.

Service, including a tune-up to manufacturer’s specifica-

tions, should be obtained immediately.

To minimize the possibility of catalytic converter dam-

age:
• 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.

• Do not idle the engine with any spark plug wires

disconnected or removed, such as when diagnostic

testing, or for prolonged periods during very rough

idle or malfunctioning operating conditions.
