WARNING!
A malfunctioning catalytic converter, as

temperatures than in normal operating
conditions. This can cause a fire if you
drive slowly or park over flammable
substances such as dry plants, wood,
cardboard, etc. This could result in death
or serious injury to the driver, occupants or
others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause
damage to the vehicle control system. It
also could affect fuel economy and
driveability. If the MIL is flashing, severe
catalytic converter damage and power loss
will soon occur. Immediate service is
required.

running, severe catalytic converter
damage and power loss will soon occur.
Immediate service is required.
