for lubrication or oil change. Replace as re-
quired.
WARNING!
•
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you. To avoid breathing CO, refer to
“Safety Tips/Exhaust Gas” in “Things To
Know Before Starting Your Vehicle” for
further information.
•
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials 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.
CAUTION!
•
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as
an emissions control device and may seri-
ously reduce engine performance and
cause serious damage to the engine.
(Continued)
CAUTION! (Continued)
•
Damage to the catalytic converter can re-
sult 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 perfor-
mance,
have your vehicle serviced
promptly. Continued operation of your ve-
hicle with a severe malfunction could
cause the converter to overheat, resulting
in possible damage to the converter and
vehicle.
Under normal operating conditions, the catalytic
converter will not require maintenance. How-
ever, it is important 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 malfunc-
tioning engine operation, a scorching odor may
suggest severe and abnormal catalyst overheat-
ing. If this occurs, stop the vehicle, turn off the
engine and allow it to cool. Service, including a
tune-up to manufacturer’s specifications, should
be obtained immediately.
To minimize the possibility of catalytic converter
damage:
•
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 malfunction-
ing operating conditions.
Cooling System
WARNING!
•
When working near the radiator cooling
fan, disconnect the fan motor lead or cycle
the ignition switch to the LOCK position.
The fan is temperature controlled and can
start at any time the ignition switch is in the
ON position.
•
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator is hot.
