4. Turn the radiator cap counterclock-
wise without pressing down on it, until it stops. This relieves any pres- sure remaining in the cooling sys-tem. And remove the radiator cap by pushing down and turning coun- terclockwise.Fill the radiator with clean deminer-alized or distilled water. Continueto add clean demineralized or dis- tilled water in small quantities until the fluid level stays up in the radia-tor neck. G050D01FC

5. Start the engine, top off the radia- tor 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 thedrain cocks are fully closed and not leaking.

To Change the Coolant
The coolant should be changed at
those intervals specified in the ve-hicle maintenance schedule in Sec- tion 5.
! CAUTION:
Engine coolant can damage the
finish of your car. If you spill en- gine 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 theradiator. Allow all the engine cool- ant to drain from the cooling sys- tem, then securely close the draincock.
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 appropriatequantity of coolant to the radiator.

3. Replace the plug and washer,
screw it in with your fingers and then tighten securely with the wrench.

AUTOMATIC TRANSAXLE
Transaxle fluid in the automatic transaxle should be checked at those intervals specified in the vehicle main- tenance schedule in Section 5. NOTE: Automatic transaxle fluid is a red color. As driving distance in- creases, the fluid color turns dark-ish red gradually. It is a normal condition and you should not judge the need to replace basedupon the changing color.You must replace the automatictransaxle fluid in accordance withintervals specified in the vehicle maintenance schedule in section 5. G110B04A-AAT
Recommended Fluid
Your Hyundai automatic transaxle is
specially designed to operate with HYUNDAI GENUINE ATF SP III, DIA- MOND ATF SP-III, SK ATF SP III orother brands approved by Hundai Motor Co,. Damage caused by a nonspecified fluid is not covered byyour new vehicle limited warranty.
G100B02A-AAT
To Check the Maunal Transaxle Fluid Level
G100B01L
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 counterclockwise 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 isnot, check for leaks before adding oil. To refill the transaxle or bring the oil level up,add oil slowly until itreaches the proper level. Do not overfill. CAUTION:
Use of aftermarket ATF additives
may cause damage to the auto-matic transaxle. Only use HYUNDAI GENUINE ATF SP III, DIAMONDATF SP III, SK ATF SP III or other brands approved by Hyundai Mo- tor Co., If you are having yourvehicle serviced at a facility other than a Hyundai dealer, verify ATF is used for your vehicle.

CHECKING THE BRAKES
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 bechecked and inspected for wear at those intervals specified in the vehicle maintenance schedule inSection 5.
WARNING (Diesel only):
Never work on injection system
with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec-tors and high pressure pipes are subject to high pressure even af- ter the engine stopped. The fuel jetproduced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers shouldnot move than 30cm closer to the ECU or wiring harness within the engine room while engine is run-ning, since the high currents in the Common Rail system produce considerable magnetic fields.
WARNING:
The cooling fan is controlled byengine coolant temperature andmay sometimes operate even when the engine is not running. Use extreme caution when workingnear the blades of the cooling fan, so that you are not injured by a rotating fan blade. As the enginecoolant temperature decreases, the fan will automatically shut off. This is a normal condition.Fluid level should be within this range
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. C090A03FC
