Exhaust System

The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the under-
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete ex-
haust system and adjacent body areas for
broken, damaged, deteriorated, or misposi-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect

the exhaust system each time the vehicle is
raised for lubrication or oil change. Replace as
required.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will de-
stroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause seri-
ous damage to the engine.
Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to assure proper catalyst opera-
tion and prevent possible catalyst damage.
CAUTION!
Damage to the catalytic converter can result if
your vehicle is not kept in proper operating
condition. In the event of engine malfunction,
particularly involving engine misfire or other
apparent loss of performance, have your ve-
hicle serviced promptly. Continued operation
of your vehicle with a severe malfunction
could cause the converter to overheat, result-
ing in possible damage to the converter and
vehicle.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such ma-
terials might be grass or leaves coming into
contact with your exhaust system. Do not park
or operate your vehicle in areas where your
exhaust system can contact anything that can
burn.
In unusual situations involving grossly malfunc-
tioning engine operation, a scorching odor may
suggest severe and abnormal catalyst over-
