Catalytic converter
The catalytic converter reduces harmful
exhaust emissions, and 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
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.
> Do not attempt to start the engine by
tow-starting. If you do so, unburned
gasoline in the catalytic converter
could ignite and cause severe dam-
age. If you have starting problems,
start the engine with an outside start-
ing aid only. Refer to page 158.
> Avoid other situations in which the
fuel is not burned or burns incom-
pletely such as frequent or extended
starter engagement or repeated start
attempts in which the engine does
not start. Stopping and restarting an
engine which is running properly
does not present a problem. Never
allow the engine to 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. Otherwise, the catalytic con-
verter could respond by overheating,
leading to serious damage.
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 at idle or when parking, take
precautions to avoid contact between
the hot exhaust system and easily flam-
mable materials (grass, hay or leaves,
for example). Such contact could lead
to a fire, resulting in serious personal in-
jury and property damage.<
