System
Your Hyundai is equipped with an emis-
sion control system to meet all require-
ments of the U.S. Environmental Protec-
tion Agency or California Air Resources
Board.
There are three emission control systems
which are as follows.
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 induction sys-
tem through the purge control solenoid
valve.
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
filtered fresh air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
then passes through the PCV valve into
the induction system.

PurgeControlSolenoidValve(PCSV)
The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant tem-
perature is low during idling, the PCSV
closes so that evaporated fuel is not taken
into the engine. After the engine warms-
up during ordinary driving, the PCSV
opens to introduce evaporated fuel to the
engine.
In order to ensure the proper function of
the emission control systems, it is recom-
mended that you have your car inspected
and maintained by an authorized Hyundai
dealer in accordance with the mainte-
nance schedule in this manual.

EvaporativeEmissionControl(In-
cluding ORVR: Onboard Refuel-
ingVaporRecovery)System
The Evaporative Emission Control Sys-
tem is designed to prevent fuel vapors
from escaping into the atmosphere.
(The ORVR system is designed to allow
the vapors from the fuel tank to be loaded
into a canister while refueling at the gas
station, preventing the escape of fuel
vapors into the atmosphere.)

ControlSystem
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performace.
