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, and 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. Slowly fill the radiator with the proper coolant
mixture (see the "Recommended Engine
Coolant in previous page) until the fluid level
stays up in the radiator neck. And pump the
radiator hose in order to bleed the air.
HNF5008
2. Wrap a thick cloth around the radiator cap
and slowly turn the radiator cap counter-
clockwise without pressing down on it, until
it stops. This relieves any pressure remain-
ing in the cooling system. When you are sure
that all the pressure has been released,
remove the radiator cap by pushing down
and turning counterclockwise.

6. Run the engine at idle until the coolant circu-
lates. If the cooling fan operates and the
coolant starts to circulate, add the coolant to
the reservoir.
7. To bleed the air in the cooling system, repeat
procedure 6 until the cooling fan operates
3~5 times.
8. Replace the radiator cap and turn it until
tightly installed. And then, add coolant to the
reservoir until the level is between "L" and
"F".
9. Stop the engine and check the coolant level
when the engine is cool. The level of the
coolant should be the "L" and "F" lines on the
reservoir. If the level is below the "L" line,
repeat the procedure 4~8 until the level
between "L" and "F".

FLUID (AUTOMATIC)G110A01E-AATTransaxle fluid in the automatic transaxle should
be checked at those intervals specified in the
vehicle maintenance schedule in Section 5.NOTE:Automatic transaxle fluid is basically red in
color. As driving distance increases, the
fluid color turns darkish red gradually. It is
a normal condition and you should not
judge the need to replace based upon the
changing color.
You must replace the automatic transaxle
fluid in accordance with intervals specified
in the vehicle maintenance 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 meeting the SP III specifica-
tion approved by Hyundai Motor Co.. Damage
caused by a nonspecified fluid is not covered by
your new vehicle limited warranty.
CAUTION:
Use of aftermarket ATF additives may cause
damage to the automatic transaxle.
Only use HYUNDAI GENUINE ATF SP III,
DIAMOND ATF SP III, SK ATF SP III or other
brands meeting the SP III specification ap-
proved by Hyundai Motor Co.. If you are
having your vehicle serviced at a facility

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 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.
