these or any other temporary
malfunctions present, the check
engine light should turn off. (A

engine startup followed by mixed
city/highway driving.)

required.If the “check engine”
light remains on, have your vehicle
serviced at the first available
opportunity.

could damage your catalytic
converter. You should drive in a
moderate fashion (avoid heavy
acceleration and deceleration) and
have your vehicle serviced at the
first available opportunity.
Under engine misfire
conditions, excessive
exhaust temperatures could
damage the catalytic converter,
the fuel system, interior floor
coverings or other vehicle com-
ponents, possibly causing a fire.
