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.
