o
3.5 V6 - To prevent the vehicle from
misfiring during dynamometer testing,
turn the Traction Control System (TCS)
off by pressing the TCS switch.
After dynamometer testing is completed,
turn the TCS system back on by pressing
the TCS switch again.
(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, pre-
venting the escape of fuel vapors into the
atmosphere.)
Your Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
There are three emission control systems which
are as follows.
Canister
Fuel vapors generated inside the fuel tank are
absorbed and stored in the canister. When the
engine is running, the fuel vapors absorbed in
the canister are drawn into the induction system
through the purge control solenoid valve.

Crankcase Emission Control
System
In order to assure the proper function of the
emission control systems, it is recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.
The positive crankcase ventilation system is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-
case. This system supplies 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
and into the induction system.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is controlled
by the Engine Control Module (ECM); when the
engine coolant temperature 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.
Caution for the Inspection and Maintenance
Test (V6 Vehicle with Traction Control Sys-
tem)

o
2.7 V6 - To prevent the vehicle from
misfiring during dynamometer testing,
disconnect the ABS connector in the
engine compartment. After dynamom-
eter testing is completed, erase the ABS/
TCS DTC (Diagnotic Trouble Code) with
a GST (Generic Scan Tool) or Hi-Scan
Pro. For more information, see shop
manual (Wheel Speed Sensor).

Exhaust Emission Control System
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle
performace.
The Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.
