converter could respond by over-
heating, leading to serious damage.
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Heat shields
are installed adjacent to some sections
of the exhaust system. Never remove
these shields; do not apply under-
coating 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
injury and property damage.<
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
damage. If you have starting prob-
lems, start the engine with an outside
starting aid only. Refer to page 171.
