Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is
correctly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
Air cleaner filter
A Genuine HYUNDAI air cleaner filter is
recommended when the filter is replaced.
Spark plugs (for gasoline engine)
Make sure to install new spark plugs of
the correct heat range.
Valve clearance
(for gasoline engine 1.6L)
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer should
perform the operation.
Cooling system
Check the cooling system parts, such as
radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid
(if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
Automatic transaxle fluid
(if equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, the fluid should
be changed at an authorized HYUNDAI
dealer in accordance to the scheduled
maintenance at the beginning of this
chapter.
✽ ✽
NOTICE
Automatic transaxle fluid color is basi-
cally red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.

FUEL FILTER (FOR DIESEL)
Draining water from fuel filter
The fuel filter for diesel engine plays an
important role of separating water from
fuel and accumulating the water in its
bottom.
If water accumulates in the fuel filter, the
warning light comes on when the ignition
switch is in the ON position.
If this warning light illuminates,
take your car to an authorized
HYUNDAI dealer and have
drain the water and checked
the system.
Extracting air from the fuel filter
If you drive until you have no fuel left or if
you replace the fuel filter, be sure to
extract air from the fuel system as it
makes it difficult to start the engine.
1. Pump up and down(1) approximately50 times until the pump is hard.
2. Extract air from the fuel filter by remov- ing the bolt(2) with a cross-tip screw
driver and reinstall the bolt(2).
3. Pump up and down(1) approximately 15 times.
4. Extract air from the fuel filter by remov- ing the bolt(2) with a cross-tip screw
driver and reinstall the bolt(2).
5. Pump up and down(1) approximately 5 times.
✽ ✽NOTICE
• Use cloths when you extract air so that
the fuel is not sprayed around.
• Clean the fuel around the fuel filter or the injection pump before starting the
engine to prevent fire.
• Finally, check each part if the fuel is leaking.
CAUTION
If the water accumulated in the fuel
filter is not drained at proper times, damages to the major parts such asthe fuel system can be caused bywater permeation in the fuel filter.

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.
There are three emission control sys-
tems which are as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control 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 author-
ized HYUNDAI dealer in accordance with
the maintenance schedule in this manu-
al.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.
After dynamometer testing is com- pleted, turn the ESP system back on
by pressing the ESP switch again.
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.
2. Evaporative emission controlSystem
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
Canister
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.
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.

Maintenance
Operating precautions for catalyticconverters (if equipped)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.
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 authorized
HYUNDAI dealer.
Avoid driving with a extremely low fuel level. Running out of fuel cause the
engine to misfire, damaging the cat-
alytic 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.Diesel Particulate Filter (if equipped)
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.
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).
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 dry grass, paper,
leaves, etc.
The exhaust system and catalytic system are very hot while the
engine is running or immediately
after the engine is turned off.
Keep away from the exhaust sys-
tem and catalytic, you may get
burned.
Also, do not remove the heat sink
around the exhaust system, do
not seal the bottom of the vehicle
or do not coat the vehicle for cor-
rosion control. It may present a
fire risk under certain conditions.

Specifications & Consumer information
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.
RECOMMENDED LUBRICANTS AND CAPACITIES
*1Refer to the recommended SAE viscosity numbers on 8-6 page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.
