Emission Control System

The emission control system of your vehicle is covered by a written limited warranty. Please refer to the warranty information contained in the Warranty Booklet in your vehicle.

Your vehicle is equipped with an emission control system that meets all applicable emission standards. There are three emission control systems as follows.

(1) Crankcase Emission Control System
(2) Evaporative Emission Control System
(3) Exhaust Emission Control System

To ensure proper operation of the emission control systems, it is recommended that your vehicle be inspected and maintained by an authorized HYUNDAI service center in accordance with the maintenance schedule.

CAUTION

For Inspection and Maintenance Test (with Electronic Stability Control (ESC))

• To prevent engine misfires during dynamometer testing, turn off the Electronic Stability Control (ESC) system by pressing the ESC switch.
• After the dynamometer test is completed, turn the ESC system back on by pressing the ESC button again.

Positive Crankcase Ventilation (PCV) System

The Positive Crankcase Ventilation system prevents air pollution from crankcase gases being released into the atmosphere. 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 intake system.

Evaporative Emission Control System

The evaporative emission control system is designed to prevent fuel vapors from escaping into the atmosphere.

Canister

Fuel vapors generated inside the fuel tank are absorbed and stored in the charcoal canister. When the engine is running, the stored fuel vapors are drawn into the intake manifold through the purge control solenoid valve.

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 idle, the PCSV closes so that evaporated fuel does not enter the engine. After the engine warms up during normal driving, the PCSV opens to supply evaporated fuel to the engine.
