9SPARK PLUGS
G060B02E-AAT
Replacing the Spark Plugs
The spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in Section 5 or whenever engine
performance indicates they should be changed.
Symptoms that suggest poor spark plug perfor-
mance include engine misfiring under load, loss
of fuel economy, poor acceleration, etc. When
spark plugs are replaced, always use spark
plugs recommended by Hyundai. The use of
other spark plugs can result in loss of perfor-
mance, radio interference or engine damage.
NOTE:When replacing the spark plugs, genuine
Hyundai replacement parts are recom-
mended.
Recommended Spark Plugs:
* 2.0L SULEV Only.CHAMPION

IRIDIUM*
G060A03Y-AAT
Your engine was originally equipped with plati-
num or iridium-tipped spark plugs.
Platinum or iridium-tipped spark plugs will last
longer than conventional type spark plugs and
can be identified by blue lines (platinum only) on
the ceramic shell.
NOTE:Do not clean or regap platinum or iridium-
tipped spark plugs.

!WARNING:The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the cooling fan so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.
This is a normal condition.

12FILLING THE WASHER RESERVOIR
G090A01A-AAT
The washer fluid reservoir supplies fluid to the
windshield washer system.
A good quality washer fluid should be used to fill
the washer reservoir. The fluid level should be
checked more frequently during inclement
weather or whenever the washer system is in
more frequent use.
The capacity of the washer reservoir is 3.2 U.S.
quarts (3.0 Liters).
G090A01E
CHECKING THE TRANSAXLE OIL
CAUTION:
o Radiator anti-freeze (engine coolant)
should not be used in the washer system
because it will damage the car's finish.
o The washer lever should not be pulled
and the washer should not be operated
if the washer reservoir is empty. This can
damage the washer fluid pump.

G100A04A-AAT
MANUAL TRANSAXLE
Transaxle lubricant in the manual transaxle
should be checked at those intervals specified
in the vehicle maintenance schedule in Section

Recommended Oil
Use only HYUNDAI GENUINE PARTS MTF
75W/90 (API GL-4) or equivalent in the manual
transaxle.
Manual Transaxle Oil Capacity
The oil capacity of the manual transaxle is 2.27
U.S. quarts (2.15 liters).

AUTOMATIC TRANSAXLE
Transaxle fluid in the automatic transaxle should
be checked at those intervals specified in the
vehicle maintenance schedule in Section 5.
NOTE:Basically automatic transaxle fluid is red
color.
As driving distance increases, the fluid
color turns darkish red gradually.
It is normal condition and you should not
judge replacing by changing color.
You must replace the automatic transaxle
fluid in accordance with intervals specified
in the vehicle maintenances schedule in
section 5.
G100B02A-AAT
To Check the Manual Transaxle
Fluid Level
Park the car on level ground with the engine off.
1. Using a wrench of the correct size, loosen
the oil filler plug by turning it counterclock-
wise and remove it with your fingers.
2. Use your finger or suitable tool to feel inside
the hole. The oil level should be at its bottom
edge. If it is not, check for leaks before
adding oil. To refill the transaxle or bring the
oil level up,add oil slowly until it reaches the
proper level. Do not overfill.
3. Replace the plug and washer, screw it in with
your fingers and then tighten securely with
the wrench.
G100B01L
!WARNING:It is always better to check the transaxle oil
level when the engine is cool or cold. If the
engine is hot, you should exercise great
caution to avoid burning yourself on hot
engine or exhaust parts.

15CHECKING THE BRAKES
G120D01A-AATTo Check the Fluid Level
The fluid level in the brake fluid reservoir should
be checked periodically. The level should be
between the "MIN" and "MAX" marks on the side
of the reservoir. If the level is at or below the
"MIN" mark, carefully add fluid to bring it up to
"MAX". Do not overfill.
!
G120C02A-AAT
Recommended Brake Fluid
Use only hydraulic brake fluid conforming to
DOT 3 or DOT 4 specifications in your braking
system. Follow the instructions printed on the
container.
G120B01A-AATChecking the Brake Fluid Level
G120A01A-AAT
CAUTION:Because brakes are essential to the safe
operation of the car, it is suggested that
they be checked and inspected by your
Hyundai dealer. The brakes should be
checked and inspected for wear at those
intervals specified in the vehicle mainte-
nance schedule in Section 5.
WARNING:Use caution when handling brake fluid. It
can damage your vision if it gets into your
eyes. It will also damage your vehicle's
paint if spilled on it and not removed imme-
diately.
!
!
3. If the transaxle fluid level is low, use a funnel
to add transaxle fluid through the dipstick
tube until the level reaches the "HOT" range.
Do not overfill.
WARNING:The cooling fan is controlled by the engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the cooling fan, so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.
This is a normal condition.
HKSOM120
Fluid level should be within this range

7EMISSION CONTROL SYSTEMS
2EMISSION CONTROL SYSTEM
H010D01A-AAT3. Exhaust Emission Control System
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle
performace.
H010B01A-AAT
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 crank-
case. 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 and into the induction system.
H010A01A-AAT
Your Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
There are three emission control systems which
are as follows.
1) Crankcase Emission Control System
2) Evaporative Emission Control System
3) Exhaust Emission Control System
In order to ensure the proper function of the
emission control systems, it is recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.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
induction system through the purge control
solenoid valve.
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 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.
H010C01S-AAT2. Evaporative Emission Control
(Including ORVR: Onboard Refueling
Vapor Recovery) System
The Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.
(The ORVR system is designed to allow the
vapors from the fuel tank to be loaded into a
canister while refueling at the gas station, pre-
venting the escape of fuel vapors into the
atmosphere.)
