Catalytic converter (gasoline engine)

Your vehicle is equipped with monolith-
G
ic-type catalytic converters, an important
element in conjunction with the oxygen
sensors to achieve substantial control of
the pollutants in the exhaust emissions.
Keep your vehicle in proper operating con-
dition by following our recommended
maintenance instructions as outlined in
your Maintenance Booklet.
!
To prevent damage to the catalytic convert-
ers, use only premium unleaded gasoline in this
vehicle.
Any noticeable irregularities in engine operation
should be repaired promptly. Otherwise, exces-
sive unburned fuel may reach the catalytic con-
verter, causing it to overheat and potentially
start a fire.
