EMISSION CONTROL SYSTEM

The emission control system of your Caution for the Inspection and

vehicle is covered by a written limited Maintenance Test (With Electronic

1. Crankcase emission control

system

The positive crankcase ventilation

system is employed to prevent air

pollution caused by blow-by gases

being emitted from the crankcase.

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 induction system.

system

The Evaporative Emission Control

System is designed to prevent fuel

vapors from escaping into the atmos-

phere.

(The ORVR system is designed to

allow the vapors from the fuel tank to

be loaded into a canister while refu-

eling at the gas station, preventing

the escape of fuel vapors into the

atmosphere.)

In order to assure the proper function

of the emission control systems, it is

recommended that you have your

vehicle inspected and maintained by

an authorized Kia dealer in accor-

dance with the maintenance sched-

ule in this manual.

3. Exhaust emission control

system

The Exhaust Emission Control

System is a highly effective system

which controls exhaust emissions

while maintaining good vehicle per-

formance.

Fuel vapors generated inside the fuel

tank are absorbed and stored in the

onboard canister.When the engine is

running, the fuel vapors absorbed in

the canister are drawn into the surge

tank through the purge control sole-

noid valve.

• Carbon monoxide can be present

with other exhaust fumes.

Therefore, if you smell exhaust

fumes of any kind inside your vehi-

cle, have it inspected and repaired

immediately. If you ever suspect

exhaust fumes are coming into

your vehicle, drive it only with all

the windows fully open. Have your

vehicle checked and repaired

immediately.

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 evap-

orated 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.

WARNING - Exhaust

Engine exhaust gases contain

carbon monoxide (CO). Though

colorless and odorless, it is

dangerous and could be lethal if

inhaled. Follow the instructions

on this page to avoid CO poi-

soning.

• Do not park, idle or drive the

vehicle over or near flamma-

A hot exhaust system can

ignite flammable items under

• Also, do not remove the heat

tem, do not seal the bottom of

the vehicle or do not coat the

It may present a fire risk under

certain conditions.

WARNING - Catalytic

Keep away from the catalytic

converter and exhaust system

while the vehicle is running or

immediately thereafter. The

exhaust and catalytic systems

are very hot and may burn you.

• Never sit in a parked or stopped

vehicle for any extended time with

the engine running.

• When the engine stalls or fails to

start, excessive attempts to restart

the engine may cause damage to

Additionally, such actions could void

your warranties.

Therefore, the following precautions

must be observed:

• Use only UNLEADED FUEL for

gasoline engines.

• Do not operate the vehicle when

there are signs of engine malfunc-

tion, such as misfire or a noticeable

loss of performance.

• Do not misuse or abuse the

engine. Examples of misuse are

coasting with the ignition off and

descending steep grades in gear

with the ignition off.

• Do not operate 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 con-

trol system. All inspections and

adjustments must be made by an

authorized Kia dealer.

• Avoid driving with an extremely low

fuel level. Running out of fuel could

cause the engine to misfire, dam-

aging the catalytic converter.
