To Change the Coolant
The coolant should be changed at those inter-
vals specified in the vehicle maintenance sched-
ule in Section 5.
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 parking
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 counterclockwise.
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.

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

12CHECKING THE TRANSAXLE
FLUID (AUTOMATIC)
!
G110A01E-AAT
Transaxle 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 a red
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 chang-
ing color.
You must replace the automatic transaxle
fluid in accordance with intervals specified
in the vehicle maintenance schedule in sec-
tion 5.
G110B03A-AATRecommended Fluid
Your Hyundai automatic transaxle is specially
designed to operate with HYUNDAI GENUINE
ATF, DIAMOND ATF SP-III or SK ATF SP-III.
Damage caused by a nonspecified fluid is not
covered by your new vehicle limited warranty.
G110C02A-AAT
Transaxle Fluid Capacity
The fluid capacity of the automatic transaxle is
6.45 U.S. quarts (6.1 liters).
WARNING:The transaxle fluid level should be checked
when the engine is at normal operating tem-
perature. This means that the engine, radia-
tor, exhaust system etc., are very hot. Exer-
cise great care not to burn yourself during
this procedure. 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.
