Catalytic converter
The catalytic converter reduces harmful
exhaust emissions.
It is designed for use with unleaded fuel
only.
Even minute quantities of lead would be
enough to permanently damage both
the catalytic converter and the system's
oxygen sensor.
To ensure efficient, trouble-free engine
operation and avoid potential damage:
>
Be sure to comply with the scheduled
maintenance requirements.
>
Fill the fuel tank well before it is
empty.
>
If the engine runs roughly, shut it off
as soon as possible.
>
Tow-start the vehicle only when the
engine is cold. Tow-starting when the
engine is warm could cause unburned
fuel to ignite in the catalytic converter,
resulting in significant damage. It is
better to start the vehicle with an out-
side starting aid.
>
Avoid any other situations in which
the fuel would not be (completely)
burned, for instance:
Frequent or consecutive extended
starting attempts or repeated starting
attempts when the engine fails to
start. (Shutting down and restarting
an engine which is running properly
does not present a problem.)
Never let the engine run with any of
the spark plug cables disconnected. Be sure to comply with the in-
structions above to prevent un-
burned fuel from reaching the catalytic
converter. This could cause overheat-
ing, leading to serious damage of the
catalytic converter.
Extreme temperatures occur at the cat-
alytic converter on this and every cata-
lyst-equipped vehicle. Heat shields are
installed adjacent to some sections of
the exhaust system. Never remove
these shields; do not apply undercoat-
ing to their surfaces.
When driving, standing while the engine
is idling, or when parking, be careful to
avoid contact between the hot exhaust
system and easily-flammable materials
(hay, dry grass, leaves, etc.). Such con-
tact could cause a fire, resulting in per-
sonal injuries and property damage.
