SERVICING AND MAINTENANCE 457
(Continued)
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to ensure proper catalyst
operation and prevent possible catalyst damage.
NOTE:
Intentional tampering with emissions control systems can
r
esu
lt in civil penalties being assessed against you.
In unusual situations involving grossly malfunctioning
engin
e 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 specifications, should
be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not interrupt the ignition when the transmission is in
gear
and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the
veh
icle.
• Do not idle the engine with any ignition components
dis
connected or removed, such as when diagnostic testing,
or for prolonged periods during very rough idle or
malfunctioning operating conditions.
Cooling System
• 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 vehicle serviced promptly. Continued opera
-
tion of your vehicle with a severe malfunction could
caus
e the converter to overheat, resulting in possible
damage to the converter and vehicle.
CAUTION! (Continued)
WARNING!
• You or others can be badly burned by hot engine
coola
nt (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 open a cooling system pressure cap when the
radiator or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry away from the
rad
iator cooling fan when the hood is raised. The fan
starts automatically and may start at any time, whether
the engine is running or not.
