G050B01A-AATRecommended Engine CoolantUse a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts.
Additional corrosion inhibitors or additives should
not be used. The cooling system must be
maintained with the correct concentration and
type of engine coolant to prevent freezing and
corrosion. Never allow the concentration of
antifreeze to exceed the 60% level or go below
the 35% level, or damage to the cooling system
may result. For proper concentration when
adding or replacing the engine coolant, refer to
the following table.
G050B01L G050A01A-AAT
WARNING:
Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and may
erupt through the opening if the cap is
removed. You could be seriously burned if
you do not observe this precaution. Do not
remove the radiator cap until the radiator is
cool to the touch.

G050D02A-AATTo Change the Engine CoolantThe engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
G050C01A-AATTo Check the Coolant LevelThe coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "L" and "F" lines on
the reservoir when the engine is cool. If the level
is below the "L" mark, add engine coolant to
bring it up between "L" and "F". If the level is low,
inspect for coolant leaks and recheck the fluid
level frequently. If the level drops again, visit
your Hyundai dealer for an inspection and
diagnosis of the reason.
G050C01L
CAUTION:
Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park-
ing brake and remove the radiator cap when
cool.
2. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, then securely close the drain cock.
3. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
!
4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclock-
wise.
Now fill the radiator with clean demineralized
or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.

SPARK PLUGSG060A02Y-AATYour engine was originally equipped with plati-
num-tipped spark plugs.
Platinum-tipped spark plugs will last longer than
conventional type spark plugs and can be
identified by blue lines on the ceramic shell.NOTE:Do not clean or regap platinum-tipped spark
plugs.
G060A01LG060B04L-AAT
Replacing the Spark PlugsThe 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.RC10PYP4 (CHAMPION)

5. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "LOW" and "FULL".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.

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 coolant 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.(3.5V6)

CHANGING THE AIR CLEANER
FILTER
!
NOTE:
o Spark plugs should be tightened firmly.
Overtightening can damage the threads
in the aluminum cylinder head. Also,
leaving them too loose can cause the
spark plug to get very hot and posibly
result in damage to the engine.
o It is recommended that spark plugs be
changed by an authorized Hyundai
dealer.
WARNING:
It is recommended that the engine be cool
or cold when changing the spark plugs. If
the engine is hot, you could burn yourself
on the insulated connector, the spark plug
or the engine itself.
G070A02Y-AATThe replacement of air cleaner filter is per-
formed in the following manner.
1. Unsnap the clips around the cover.
2. When this is done, the cover can be lifted off,
the old filter removed and the new filter put in
its place.
Genuine Hyundai replacement parts are rec-
ommended.
CAUTION:
Operating your vehicle without a proper air
cleaner filter in place can result in excessive
engine wear. When removing the air cleaner
filter, be careful that dust or dirt does not
enter the air intake. These may result in
damage to the air cleaner filter.

FILLING THE WASHER RESERVOIR
WINDSHIELD WIPER BLADES
G090A01A-AATThe 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).
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 should not be operated if the
washer reservoir is empty. This can dam-
age the washer fluid pump.
HXG2007
G080A02A-AATThe wiper blades should be carefully inspected
from time to time and cleaned to remove accu-
mulations of road film or other debris. To clean
the wiper blades and arms, use a clean sponge
or cloth with a mild soap or detergent and water.
If the wipers continue to streak or smear the
glass, replace them with genuine Hyundai re-
placement parts or their equivalent.
HEF119
!
CAUTION:
o Do not operate the wipers on dry glass.
This can result in more rapid wear of the
wiper blades and may scratch the glass.

CHECKING THE TRANSAXLE
FLUID
!
G110A01E-AATTransaxle 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 use
fluid color as a criterion for replacing the
transaxle fluid.
You must replace the automatic transaxle
fluid in accordance with intervals specified
in the vehicle maintenances schedule in
section 5.
G110B05A-AATRecommended FluidYour Hyundai automatic transaxle is specially
designed to operate with HYUNDAI GENUINE
ATF SP III, DIAMOND ATF SP III, SK ATF SP
III or other brands approved by Hyundai Motor
Co., Damage caused by a nonspecified fluid is
not covered by your new vehicle limited war-
ranty.
G110C01L-AATTransaxle Fluid CapacityThe fluid capacity of the automatic transaxle is
9.1 U.S. quarts.
WARNING:
The transaxle fluid level should be checked
when the engine is at normal operating
temperature. This means that the engine,
radiator, exhaust system etc., are very hot
so you should exercise great care not to
burn yourself during this procedure.
CAUTION:
Use of aftermarket ATF additives may cause
damage to the automatic transaxle. Only
use HYUNDAI GENUINE ATF SP III, DIA-
MOND ATF SP III, SK ATF SP III or other
brands approved by Hyundai Motor Co., If
you are having your vehicle serviced at a
facility other than a Hyundai dealer, verify
ATF is used for your vehicle.

to add transaxle fluid through the dipstick
tube until the level reaches the "HOT" range.
Do not overfill.
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.
While the engine is idling, apply the brakes and
move the gear selector lever from "P" to each
of its other positions -- "R", "N", "D" -- and then
to "N" with the engine still idling:
1. Open the hood, being careful to keep hands,
long hair and clothing clear of any moving
parts.
2. Remove the transaxle dipstick, wipe it clean,
reinsert the dipstick as far as it will go, then
remove it again. Now check the fluid level on
the dipstick. It should be in the "HOT" range
on the dipstick.
3. Return the gear selector to the "P" position.

G140A01A-AATKeeping the Condenser CleanThe air conditioning condenser (and engine
radiator) should be checked periodically for
accumulation of dirt, dead insects, leaves, etc.
These can interfere with maximum cooling ef-
ficiency. When removing such accumulations,
brush or hose them away carefully to avoid
bending the cooling fans.
G140B01A-AATChecking the Air Conditioning Opera-
tion1. Start the engine and let it run at a fast idle for
several minutes with the air conditioning set
at the maximum cold setting.
2. If the air coming out of the in-dash vents is
not cold, have the air conditioning system
inspected by your Hyundai dealer.
CAUTION:
Running the air conditioning system for
extended periods of time with a low refrig-
erant level may damage the compressor.
!
G140C01A-AATLubricationTo lubricate the compressor and the seals in the
system, the air conditioning should be run for at
least 10 minutes each week. This is particularly
important during cool weather when the air
conditioning system is not otherwise in use.

G190A01A-AATDrive belts should be checked periodically for
proper tension and adjusted if necessary. At the
same time, belts should be examined for cracks,
wear, fraying or other evidence of deterioration
and replaced if necessary.
Belt routing should also be checked to be sure
there is no interference between the belts and
other parts of the engine. After a belt is replaced,
the new belt should be adjusted again after two
or three weeks to eliminate slack resulting from
initial stretching after use.
