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.

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.
CHECKING AND CHANGING THE
ENGINE COOLANT!
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.

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. 2. 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.
3. 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.
4. 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.
5. Fill the radiator with clean demineralized or
distilled water. Continue to add clean dem-
ineralized or distilled water in small quantities
until the fluid level stays up in the radiator
neck.6. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "L" and "F".
7. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
G050D02A-AATTo Change the Engine CoolantThe engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
HJM5034G050D01JM
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.

FILLING THE WASHER RESERVOIRG090A02JM-AATThe washer fluid reservoir supplies fluid to the
front and rear washer systems.
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 3.59
U.S. quarts (3.4 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.
!!
WARNING:
o Windshield washer fluid agents contain
some amounts of alcohol and can be
flammable under certain circumstances.
Do not allow sparks or flame to contact
the washer fluid or the washer fluid
reservoir. Damage to the vehicle or its
occupants could occur.
o Windshield washer fluid is poisonous to
humans and animals. Do not drink wind-
shield washer fluid. Serious injury or
death could occur.

G100B02A-AATTo Check the Manual Transaxle Fluid
Level
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.
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.

!
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.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.
When the air conditioning is being used regu-
larly, the compressor drive belt tension should
be checked at least once a month with the
engine turned off.
To check the drive belt tension, press down on
the belt halfway between the engine crankshaft
and compressor pulleys. Pressing with your
finger, you should not be able to deflect this belt
anymore than 1/3 of an inch. If the belt is too
loose, have it adjusted by your Hyundai dealer.
