The engine coolant should be compat-
ible with aluminum engine parts. Addi- tional corrosion inhibitors or additives should not be used. The cooling sys- tem must be maintained with the cor-rect concentration and type of engine coolant to prevent freezing and corro- sion. Never allow the concentration ofantifreeze to exceed the 60% level or go below the 35% level, or damage to the cooling system may result. Forproper concentration when adding or replacing the engine coolant, refer to the following table. G050C01A-GAT To Check the Coolant Level

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 parking brake and remove the radia- tor 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.
!
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.
WARNING:
Remove the radiator cap when theradiator is cool.
The level of the coolant should bebetween the "L" and "F" lines on thereservoir when the engine is cold. 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 dropsagain, visit your Hyundai dealer for an inspection and diagnosis of the rea- son.

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 draincocks are fully closed and not leak- ing.
!WARNING:
The cooling fan is controlled by
engine coolant temperature and may sometimes operate even when theengine is not running. Use extreme caution when working near the blades of the cooling fan so thatyou are not injured by a rotating fan blade. As the engine coolant tem- perature decreases, the fan will au-tomatically shut off. This is a nor- mal condition.

To Check the Transaxle Fluid Level
Park the car on level ground with the
parking brake engaged. When the transaxle fluid level is checked, the transaxle fluid should be at normaloperating temperature and the en- gine idling. 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", "2", "L" -- and then return to "N" or "P". With theengine 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 faras 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. HFC5008

CHECKING THE BRAKES
G120A01A-AAT
! CAUTION:
Because brakes are essential to the safe operation of the car, it issuggested 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

Adding Brake Fluid
WARNING:
Handle brake fluid carefully. It can damage your vision if it gets into your eyes. Use only DOT 3 or DOT4 specification fluid from a sealed container. Do not allow the fluid can or reservoir to remain openany longer than required. This will prevent entry of dirt and moisture which can damage the brake sys-tem and cause improper opera- tion. To add brake fluid, first wipe away any dirt then unscrew the fluid reser-voir cap. Slowly pour the recom- mended fluid into the reservoir. Do not overfill. Carefully replace the capon the reservoir and tighten. HFC5005

G130B02A-AAT To Replace the Fluid Recommended brake fluid conform- ing to DOT 3 or DOT 4 specification should be used. The reservoir cap must be fully tightened to avoid con-tamination from foreign matter or moisture. NOTE: Do not allow any other liquids to contaminate the brake fluid. Sealdamage will result.
WARNING:
Use caution when handling brake fluid. It can damage your vision if you get it in your eyes. It will alsodamage your vehicle's paint if spilled on it and not removed im- mediately.
AIR CONDITIONING CARE
G140A01A-AAT
Keeping the Condenser Clean
The air conditioning condenser (and
engine radiator) should be checked periodically for accumulation of dirt, dead insects, leaves, etc. These caninterfere with maximum cooling effi- ciency. When removing such accu- mulations, brush or hose them awaycarefully to avoid bending the cooling fans. G140B01A-AAT
Checking the Air Conditioning Operation
1. Start the engine and let it run at a
fast idle for several minutes with the air conditioning set at the maxi-mum cold setting.
2. If the air coming out of the in-dash
vents is not cold, have the air con-ditioning system inspected by your Hyundai dealer. G140C01A-AAT
Lubrication
To lubricate the compressor and the
seals in the system, the air condition-ing should be run for at least 10 minutes each week. This is particu-larly important during cool weather when the air conditioning system is not otherwise in use. CAUTION:
Running the air conditioning sys-
tem for extended periods of timewith a low refrigerant level maydamage the compressor.
