EMISSION CONTROL SYSTEM

G270000AFD-EA

G270200AFD-EA

Caution for the Inspection and

Maintenance Test (With Electronic

Stability Program (ESP) system)

• To prevent the vehicle from misfir-

ing during dynamometer testing,

turn the Electronic Stability

Program (ESP) system off by press-

ing the ESP switch.

The emission control system of your

vehicle is covered by a written limited

warranty. Please see the warranty infor-

mation contained in the Service Passport

in your vehicle.

Your vehicle is equipped with an emis-

sion control system to meet all Australian

Design Rules (ADR) requirements.

2. Evaporative emission control

System

The Evaporative Emission Control

System is designed to prevent fuel

vapours from escaping into the atmos-

phere.

• After dynamometer testing is com-

pleted, turn the ESP system back on

by pressing the ESP switch again.

G270201AUN-EA

There are three emission control sys-

tems which are as follows.

Canister

Fuel vapours generated inside the fuel

tank are absorbed and stored in the

onboard canister. When the engine is

running, the fuel vapours absorbed in the

canister are drawn into the surge tank

through the purge control solenoid valve.

(1) Crankcase emission control system

(2) Evaporative emission control system

(3) Exhaust emission control system

G270100AUN

1. Crankcase emission control

system

The positive crankcase ventilation sys-

tem 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.

In order to assure the proper function of

the emission control systems, it is rec-

ommended that you have your car

inspected and maintained by an autho-

rised HYUNDAI dealer in accordance

with the maintenance schedule in this

manual.

G270202AUN

Purge Control Solenoid Valve (PCSV)

The purge control solenoid valve is con-

trolled by the Engine Control Module

(ECM); when the engine coolant temper-

ature is low during idling, the PCSV clos-

es so that evaporated 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.

Operating precautions for catalytic

converters (if equipped)

3. Exhaust emission control

system

The Exhaust Emission Control System is

a highly effective system which controls

exhaust emissions while maintaining

good vehicle performance.

WARNING - Exhaust

Engine exhaust gases contain car-

bon monoxide (CO). Though

colourless and odourless, it is dan-

gerous and could be lethal if

inhaled. Follow the instructions

following to avoid CO poisoning.

WARNING - Fire

A hot exhaust system can ignite

flammable items under your vehi-

cle. Do not park, idle, or drive the

vehicle over or near flammable

objects, such as grass, vegetation,

paper, leaves, etc.

G270301AUN

Vehicle modifications

• Do not operate the engine in confined

or closed areas (such as garages) any

more than what is necessary to move

the vehicle in 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 needed) to draw

outside air into the vehicle.

• Never sit in a parked or stopped vehi-

cle 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 the

emission control system.

This vehicle should not be modified.

Modification of your vehicle could affect

its performance, safety or durability and

may even violate governmental safety

and emissions regulations.

In addition, damage or performance

problems resulting from any modification

may not be covered under warranty.

Your vehicle is equipped with a catalytic

converter emission control device.

Therefore, the following precautions

must be observed:

• Use only UNLEADED FUEL for petrol

engine.

• Do not operate the vehicle when there

are signs of engine malfunction, such

as misfire or a noticeable loss of per-

formance.

G270302AUN-EA

Engine exhaust gas precautions (car-

bon monoxide)

• Carbon monoxide can be present with

other exhaust fumes. Therefore, if you

smell exhaust fumes of any kind inside

your vehicle, have it inspected and

repaired immediately. If you ever sus-

pect exhaust fumes are coming into

your vehicle, drive it only with all the

windows fully open. Have your vehicle

checked and repaired immediately.

• 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.

Maintenance

• 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 control sys-

tem. All inspections and adjustments

must be made by an authorised

HYUNDAI dealer.

• Avoid driving with a very low fuel level.

If you run out of petrol, it could cause

the engine to misfire and result in

excessive loading of the catalytic con-

verter.

Failure to observe these precautions

could result in damage to the catalytic

converter and to your vehicle.

Additionally, such actions could void your

warranty.

Diesel Particulate Filter (if equipped)

If the malfunction indicator light contin-

ues to be blinked in spite of the proce-

dure, please visit an authorised

HYUNDAI dealer and then check the

DPF system.

If you continue to drive with the malfunc-

tion indicator light blinking for a long

time, the DPF system can be damaged

and fuel consumption can be worsen.

The Diesel Particulate Filter (DPF) sys-

tem removes the soot emitted from the

vehicle.

Unlike a disposable air filter, the DPF

system automatically burns (oxidizes)

and removes the accumulated soot

according to the driving condition. In

other words, the active burning by engine

control system and high exhaust gas

temperature caused by normal/high driv-

ing condition burns and removes the

accumulated soot.

However, if the vehicle continues to be

driven at low speed for long time, the

accumulated soot may not be automati-

cally removed because of low exhaust

gas temperature. In this particular case,

the amount of soot is out of detection

limit, the soot oxidation process by

engine control system may not happen

and the malfunction indicator light may

blink.

CAUTION - Diesel Fuel

(if equipped with DPF)

It is recommended to use the regu-

lated automotive diesel fuel for

diesel vehicle equipped with the

DPF system.

If you use diesel fuel including high

sulfur (more than 50 ppm sulfur)

and unspecified additives, it can

cause the DPF system to be dam-

aged and white smoke can be emit-

ted.

When the malfunction indicator light

blinks, it may stop blinking by driving the

vehicle at more than 60km/h (37 mph) or

at more than second gear with 1500 ~

2000 engine rpm for a certain time (for

about 25 minutes).
