1. Crankcase emission control
system
The  positive  crankcase  ventilation  sys-
tem is  employed to  prevent air  pollution
caused by  blow-by gases  being emitted
from the crankcase.This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh  air  mixes with  blow-by gases,
which then  pass through the  PCV valve
into the induction system.
In order  to assure the  proper function of
the emission control systems, it is recom-
mended   that   you  have   your   vehicle
inspected and  maintained by  an author-
ized HYUNDAI dealer in accordance with
the maintenance schedule in this manual.
