Emission Control System

Your vehicle's emissions control system is covered by a written limited warranty. Please refer to the warranty information contained in the Warranty and Consumer Information manual in your vehicle.

Your vehicle is equipped with an emissions control system that meets all applicable emissions regulations.

There are three emissions 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 emissions control systems, it is recommended that your vehicle be inspected and serviced by an authorized Kia dealer in accordance with the maintenance schedule in this manual.

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

• To prevent the vehicle from stalling during the dynamometer test, turn the Electronic Stability Control (ESC) system off by pressing the ESC button.
• After the dynamometer test is completed, turn the ESC system back on by pressing the ESC button again.

1. 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.

2. Evaporative Emission Control System (including ORVR: On-Board Refueling Vapor Recovery) System

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

(The ORVR system is designed to allow fuel vapors from the fuel tank to be loaded into the canister when refueling at a gas station, preventing fuel vapor from escaping into the atmosphere.)

Canister

Fuel vapors generated inside the fuel tank are absorbed and stored in the onboard canister. When the engine is running, the absorbed fuel vapors are drawn from the canister 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.

3. Exhaust Emission Control System

The Exhaust Emission Control System is a highly efficient system that controls exhaust emissions while maintaining good vehicle performance.

Precautions for Engine Exhaust Gas (Carbon Monoxide)

• Carbon monoxide may be present with other exhaust gases. Therefore, if you smell exhaust fumes or smoke of any kind inside your vehicle, have it checked and repaired immediately. If you ever suspect exhaust gases are entering your vehicle, drive it only with all windows fully open. Have your vehicle checked and repaired immediately.

WARNING - Exhaust

Engine exhaust contains carbon monoxide (CO). Although colorless and odorless, it is dangerous and may cause death if inhaled. Follow the instructions on this page to avoid carbon monoxide poisoning.

• Do not operate the engine in enclosed or confined areas (such as garages) longer than necessary to move the vehicle into or out of the area.
• When the vehicle is stopped in an open area for more than a short time with the engine running, adjust the ventilation system (as necessary) to draw outside air into the vehicle.
• Never sit in a parked or stopped vehicle for extended periods with the engine running.
• When the engine stalls or does not start, excessive cranking may damage the emission control system.

Precautions for Operating the Catalytic Converter (if equipped)

WARNING - Catalytic Converter

Stay away from the catalytic converter and exhaust system while the vehicle is running or immediately after it has been driven. The exhaust and catalytic systems are very hot and can burn you.

WARNING! Fire

• Do not park, idle, or drive the vehicle over or near flammable objects such as grass, vegetation, paper, leaves, etc. The hot exhaust system can ignite flammable objects under your vehicle.
• In addition, do not remove heat shields around the exhaust system, do not undercoat the vehicle, or apply rust-proofing material. This may create a fire hazard under certain conditions.

Your vehicle is equipped with a catalytic converter emission control device.

Therefore, the following precautions must be observed:

• Use only UNLEADED FUEL for gasoline engines.
• Do not drive the vehicle when there are signs of engine malfunction, such as misfiring or noticeable loss of performance.
• Do not abuse or misuse the engine. Examples of misuse include coasting with the ignition switched off and driving downhill in gear with the ignition switched off.
• Do not run the engine at high idle speed for extended periods (5 minutes or more).
• Do not modify or tamper with any part of the engine or emission control system. All inspections and adjustments must be performed by an authorized Kia dealer.
• Avoid driving with a very low fuel level. Running out of fuel may cause engine misfires, which can damage the catalytic converter.

Failure to observe these precautions may damage the catalytic converter and your vehicle. In addition, such actions may void your warranty.
