Emission Control System

The emission control system of your vehicle is covered by a written limited warranty. Refer to the warranty information contained in the Warranty and Maintenance booklet provided with your vehicle.

Your vehicle is equipped with an emission control system that meets all applicable emission standards.

There are the following three emission control systems.

(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 serviced by an authorized Kia dealer according to the maintenance schedule in this manual.

Precautions for Inspection and Maintenance (with Electronic Stability Control (ESC) System)

• To prevent the vehicle from misfiring during dynamometer testing, turn off the Electronic Stability Control (ESC) system by pressing the ESC switch.
• After completing the dynamometer test, turn the ESC system back on by pressing the ESC switch again.

1. Crankcase Emission Control System

The crankcase ventilation system is used to prevent air pollution caused by crankcase gases escaping into the atmosphere.

This system supplies fresh filtered air into the engine crankcase through the air intake hose. Inside the crankcase, the fresh air mixes with the crankcase gases, which then pass through the PCV valve into the intake system.

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

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

(The ORVR system is designed to route vapors from the fuel tank to the canister during refueling at a gas station, preventing fuel vapors from escaping into the atmosphere).

Canister

Fuel vapor generated inside the fuel tank is absorbed and stored in the onboard canister. When the engine is running, the fuel vapor absorbed by the canister is drawn into the intake manifold through the Purge Control Solenoid Valve (PCSV).

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 at 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 effective system that controls exhaust emissions while maintaining good vehicle performance.

Vehicle Modifications

This vehicle must not be modified. Modifying your vehicle may affect its performance, safety or durability and may even violate federal safety and emissions regulations.

In addition, damage or performance problems resulting from any modification may not be covered by the warranty.

Use of unauthorized electronic devices may cause the vehicle to malfunction, damage wiring, discharge the battery, and cause a fire. For your safety, do not use unauthorized electronic devices.

Engine Exhaust Precautions (Carbon Monoxide)

Carbon monoxide may be present in other exhaust gases.

Therefore, if you smell exhaust gas inside your vehicle, have it inspected and repaired immediately. If you ever suspect that exhaust gas is entering the vehicle, drive it only with all windows fully open. Have your vehicle inspected and repaired immediately.

WARNING - Exhaust

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

CALIFORNIA PROPOSITION 65 WARNING

Engine exhaust, and some vehicle components and parts, including interior trim components, contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. In addition, some fluids contained in vehicles and certain component wear products contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

• Do not operate the engine in enclosed or confined areas (such as garages) any longer than necessary to enter or exit 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 (if necessary) to draw outside air into the vehicle.
• Never sit in a parked or stopped vehicle for a long period with the engine running.
• When the engine stalls or fails to start, excessive attempts to restart the engine may cause damage to the emission control system.

Precautions for Operating Catalytic Converters (if equipped)

WARNING! Fire

• The hot exhaust system may ignite flammable objects under the vehicle. Do not park, stop, or drive the vehicle over or near flammable objects such as grass, vegetation, paper, leaves, etc.
• The exhaust system and catalytic converter are very hot while the engine is running or immediately after the engine is turned off. Keep away from the exhaust system and catalytic converter, as you may get burned. Also, do not remove heat shields around the exhaust system, do not seal the underbody, and do not apply rust-proofing to the vehicle. This may create a fire hazard under certain conditions.

Your vehicle is equipped with a catalytic converter.

Therefore, observe the following precautions:

• Use only UNLEADED FUEL for gasoline engines.
• Do not drive the vehicle if you notice signs of engine malfunction, such as misfiring or a noticeable loss of performance.
• Do not misuse or abuse the engine. Examples of misuse include coasting with the ignition switched off and descending steep hills in gear with the ignition switched off.
• Do not run the engine at high idle speed for a long time (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 very low fuel. Running out of fuel may cause engine misfires and damage to the catalytic converter.

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