Emissions control
systems
Catalytic converter
Applies to vehicles a with gasoli ne engine : the
vehicle may only be driven with unleaded gaso­ li ne, otherwise the cata lytic converter will be de­
stroyed .
Never dr ive until the tank is complete ly empty.
The irregu lar supply of fuel that resu lts from that
can cause eng ine misfires. Uncombusted fue l will
enter the exhaust system, which can cause over­
hea ting and damage to the cata lytic converter .
Diesel particulate filter
Applies to vehicle s with a diesel engine : the die­
sel part icu late filter filters nearly all of the soot
particles out of the exhaust. The f ilter cleans it­
self automatically under normal dr iv ing cond i­
t ions .
If the filter cannot clean itself (fo r exam­
ple, bec ause you are only d rivi ng short distan­
c es), the filte r becomes clogged wi th soo t and

pa rtic ulate filter) could start a fire.
