The catalytic converter is an effic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the polluta nts in the exhaust gas be­
fore they are released into the atmosphe re. The exclusive
use of unleaded f uel is critica lly
important for the life of the catalytic convert­
er and proper funct ion ing of the eng ine .

areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fuel spill or other material wh ich can
