Your vehicle is equipped with monolithic-
type catalytic converters, an important el-
ement in conjunction with the oxygen sen-
sors to achieve substantial control of the
pollutants in the exhaust emissions. Keep
your vehicle in proper operating condition
by following our recommended mainte-
nance instructions as outlined in your Ser-
vice Booklet.Your vehicle is equipped with an oxidation

CAUTION
To prevent damage to the catalytic con-
verters, only use premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise, excessive unburned fuel
may reach the catalytic converter,
causing it to overheat and potentially
start a fire.

outward on each square inch of the tire.
Air pressure is expressed in pounds per
square inch (psi), or kilopascal (kPa) or
bars.
Aspect ratio
Dimensional relationship between the tire
section height and the section width ex-
pressed in percentage.Bar
Another metric unit for air pressure. There
are 14.5038 pounds per square inch (psi)
to 1 bar; there are 100 kilopascals (kPa)
to 1 bar.
