Catalytic converter
It is very important that your emission con­
trol system (catalytic conv ert er) is function ­
ing properly to ensure that your vehicle is run­
ning in on env ironm entally sound manner.
,,. Always use lead-free gaso line Q page 201,
Fuel supply .
,,. Never run the tank down a ll th e way to emp ­
ty.
,,. Never put too much moto r oil in your engine
Q page 211 , ~ Adding engine oil .
,,. Never try to push -or tow -start your ve hicle .
T he cata lytic converter is an eff ic ient "clean­
up" device built in to 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 exclus
ive use of unleaded f uel is critica lly
important for the life of the catalytic conv ert­
er and p roper funct ion ing of the eng ine .
A WARNING
=
-The temperature of the exhaust system
is high, both when driving and after stop­
p ing the eng ine .
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle i n
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ver ter or he at s hields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
