system

(2) Evaporative emission control sys-

tem

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.

(3) Exhaust emission control system

Purge Control Solenoid Valve

(PCSV)

In order to assure the proper function

of the emission control systems, it is

recommended that you have your

car inspected and maintained by an

authorized HYUNDAI dealer in

accordance with the maintenance

schedule in this manual.

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.

Maintenance

• Do not operate the engine in con-

fined or closed areas (such as

garages) any more than what is

necessary to move the vehicle in or

out of the area.

Engine exhaust gas precautions

(carbon monoxide)

3. Exhaust emission control

system

• 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.

The Exhaust Emission Control

System is a highly effective system

which controls exhaust emissions

while maintaining good vehicle per-

formance.

• 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.

Vehicle modifications

This vehicle should not be modified.

Modification of your vehicle could

affect its performance, safety or

durability and may even violate gov-

ernmental safety and emissions reg-

ulations.

• Never sit in a parked or stopped

vehicle for any extended time with

the engine running.

WARNING

• When the engine stalls or fails to

start, excessive attempts to restart

the engine may cause damage to

the emission control system.

In addition, damage or performance

problems resulting from any modifi-

cation may not be covered under

warranty.

Exhaust

Engine exhaust gases contain

carbon monoxide (CO). Though

colorless and odorless, it is

dangerous and could be lethal if

inhaled. Follow the instructions

following to avoid CO poison-

ing.

• If you use unauthorized electronic

devices, it may cause the vehicle to

operate abnormally, wire damage,

battery discharge and fire. For your

safety, do not use unauthorized

electronic devices.

ic converter and to your vehicle.

Additionally, such actions could void

your warranties.

Therefore, the following precautions

must be observed:

WARNING

Fire

• Use only UNLEADED FUEL for

gasoline engine.

• A hot exhaust system can

ignite flammable items under

your vehicle. Do not park,

idle, or drive the vehicle over

or near flammable objects,

such as dry grass, paper,

leaves, etc.

• 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.

• The exhaust system and cat-

alytic system are very hot

while the engine is running or

immediately after the engine

is turned off. Keep away from

the exhaust system and cat-

alytic, you may get burned.

• 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 HYUNDAI dealer.

Also, do not remove the heat

sink around the exhaust sys-

tem, do not seal the bottom of

the vehicle or do not coat the

vehicle for corrosion control.

It may present a fire risk under

certain conditions.

• Avoid driving with a very low fuel

level. If you run out of gasoline, it

could cause the engine to misfire

and result in excessive loading of

the catalytic converter.

7-99

Maintenance

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).

Diesel Particulate Filter

(if equipped)

CAUTION

The Diesel Particulate Filter (DPF)

system removes the soot emitted

from the vehicle.

Diesel Fuel

(if equipped with DPF)

It is recommended to use the

regulated automotive diesel

fuel for diesel vehicle equipped

with the DPF system.

Unlike a disposable air filter, the DPF

system automatically burns (oxi-

dizes) and removes the accumulated

soot according to the driving condi-

tion. In other words, the active burn-

ing by engine control system and

high exhaust gas temperature

caused by normal/high driving condi-

tion burns and removes the accumu-

lated soot.

If the malfunction indicator light con-

tinues to be blinked in spite of the

procedure, please visit an authorized

HYUNDAI dealer and then check the

DPF system.

If you use diesel fuel including

high sulfur (more than 50 ppm

sulfur) and unspecified addi-

tives, it can cause the DPF sys-

tem to be damaged and white

smoke can be emitted.

If you continue to drive with the mal-

function indicator light blinking for a

long time, the DPF system can be

damaged and fuel consumption can

be worsen.

However, if the vehicle continues to

be driven at low speed for long time,

the accumulated soot may not be

automatically removed because of

low exhaust gas temperature. In this

particular case, the amount of soot is

out of detection limit, the soot oxida-

tion process by engine control sys-

tem may not happen and the mal-

function indicator light may blink.
