Maintenance

EMISSION CONTROL SYSTEM

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 emission

regulations.

Caution for the Inspection and

Maintenance Test (With Electronic

Stability Control (ESC) system)

• To prevent the vehicle from misfir-

ing during dynamometer testing,

turn the Electronic Stability Control

(ESC) system off by pressing the

ESC switch.

2. Evaporative emission control

System

The Evaporative Emission Control

System is designed to prevent fuel

vapors from escaping into the atmos-

phere.

Canister

There are three emission control sys-

tems which are as follows.

• After dynamometer testing is com-

pleted, turn the ESC system back on

by pressing the ESC switch again.

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 solenoid valve.

(1) Crankcase emission control system

(2) Evaporative emission control system

(3) Exhaust emission control system

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.

Purge Control Solenoid Valve (PCSV)

In order to assure the proper function of

the emission control systems, it is rec-

ommended that you have your vehicle

inspected and maintained by an author-

ized HYUNDAI dealer in accordance with

the maintenance schedule in this manu-

al.

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.

Engine exhaust gas precautions

(carbon monoxide)

• 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.

3. Exhaust emission control

system

The Exhaust Emission Control System is

a highly effective system which controls

exhaust emissions while maintaining

good vehicle performance.

• 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.

Vehicle modifications

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.

WARNING - Exhaust

Engine exhaust gases contain car-

bon monoxide (CO). Though color-

less and odorless, it is dangerous

and could be lethal if inhaled.

Follow the instructions following to

avoid CO poisoning.

Maintenance

Operating precautions for catalytic

converters (if equipped)

• 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. We recommend that the system

be inspected by an authorized

HYUNDAI dealer.

• Avoid driving with a very low fuel level.

If you run out of gasoline, it could

cause the engine to misfire and dam-

age the catalytic converter.

Failure to observe these precautions

could result in damage to the catalytic

converter and to your vehicle.

Additionally, such actions could void your

warranties.

WARNING - Fire

A hot exhaust system can ignite

flammable items under your vehi-

cle. Do not park the vehicle over or

near flammable objects, such as

grass, vegetation, paper, leaves,

etc.

Your vehicle is equipped with a catalytic

converter emission control device.

Therefore, the following precautions

must be observed:

• Use only UNLEADED FUEL for gaso-

line engine.

• Do not operate the vehicle when there

are signs of engine malfunction, such

as misfire or a noticeable loss of per-

formance.

• 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.
