2. Evaporative Emission Control System

The evaporative emission control system is designed to prevent 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.

Engine Exhaust Precautions (Carbon Monoxide)

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

WARNING

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

• 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.
