EMISSION CONTROL SYSTEM

The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty in-
formation contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
emission regulations.
There are three emission control sys-
tems which are as follows.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys-
tem
(3) Exhaust emission control system
In order to ensure the proper function
of the emission control systems, it is
recommended that you have your car
inspected and maintained by an au-
thorized HYUNDAI dealer in accor-
dance with the maintenance sched-
ule in this manual.

1. Crankcase emission control
system
The positive crankcase ventilation
system 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 in-
take hose. Inside the crankcase, the
fresh air mixes with blow-by gases,
which then pass through the PCV
valve into the induction system.
2. Evaporative emission con-
trol system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmo-
sphere.
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
