during ordinary driving, the PCSV
opens to introduce evaporated fuel
to the engine.

Engine exhaust gas precautions

Carbon monoxide can be present
with other exhaust fumes. There-
fore, if you smell exhaust fumes
of any kind inside your vehicle,
have it inspected and repaired
immediately. If you ever suspect
exhaust fumes are coming into
your vehicle, drive it only with all
the windows fully open. Have your
vehicle checked and repaired
immediately.
