G050C01TG-GAT To Check the Coolant Level Gasoline Engine The coolant level can be seen on the side of the plastic coolant reservoir.
OMC057007
OMC059008A
Diesel Engine The level of the coolant should be between 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 drops again,visit your Hyundai dealer for an inspec- tion and diagnosis of the reason.
!WARNING:
The cooling fan is controlled by en- gine coolant temperature and may sometimes operate even when theengine is not running. Use extreme caution when working near the blades of the coolant fan so that youare not injured by a rotating fan blade. As the engine coolant tem- perature decreases, the fan will auto-matically shut off. This is a normal condition.
! CAUTION:
o 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.
o The engine in your vehicle has
aluminum engine parts and mustbe protected by an ethylene-gly- col base coolant to prevent corro-sion and freezing. And, do not use the hard water. The hard water can cause enginedamage from corrosion, overheat- ing or freezing.

CAUTION:
o Radiator antifreeze (engine cool- ant) should not be used in the washer system because it will damage the car's finish.
o The washer should not be oper- ated if the washer reservoir isempty. This can damage thewasher fluid pump.!
WARNING:
o Windshield washer fluid agents contain some amounts of alcohol and can be flammable under cer- tain circumstances. Do not allow sparks or flame to contact thewasher fluid or the washer fluid reservoir. Damage to the vehicle or its occupants could occur.
o Windshield washer fluid is poi- sonous to humans and animals.Do not drink windshield washerfluid. Serious injury or death could occur.
CHECKING THE TRANSAXLE OIL (MANUAL)
G100A01MC-GAT
Transaxle lubricant in the manual transaxle should be checked at those intervals specified in the vehicle main-tenance schedule in Section 5.
!WARNING:
It is always better to check the transaxle oil level when the engine iscool or cold. If the engine is hot, you should exercise great caution to avoid burning yourself on hot en-gine or exhaust parts. NOTE: It is recommended that the manual transaxle fluid should be checked by an authorized Hyundai dealer.
FILLING THE WASHER RESERVOIR
G090A01MC-GAT The washer fluid reservoir supplies fluid to the windshield washer system. A good quality washer fluid should be used to fill the washer reservoir. Thefluid level should be checked more frequently during inclement weather or whenever the washer system is in morefrequent use. OMC055016

15CHECKING THE TRANSAXLE FLUID (AUTOMATIC)
G110A01MC-AAT 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 basi- cally a red color. As driving distance increases, the fluid color turns dark-ish red gradually. It is normal condi- tion and you should not judge the need to replace based upon thechanging color. You must replace the automatic transaxle fluid in accordance withintervals specified in the vehicle maintenance schedule in section 5.
!WARNING:
The transaxle fluid level should be checked when the engine is at nor- mal operating temperature. This means that the engine, radiator,exhaust system etc., are very hot. Exercise great care not to burn your- self during this procedure. G110D03A-GAT To Check the Transaxle Fluid Level
The automatic transaxle fluid level should be checked regularly. Keep the vehicle on level ground withthe parking brake applied and check the fluid level according to the following procedure. OMC0590061. Place the shift lever in N(neutral)
position and confirm the engine isrunning at normal idle speed.
2. After the transaxle is warmed up
sufficiently [fluid temperature70~80°C (158~176°F)], for example by 10 minutes usual driving, move the shift lever through all positionsthen place the shift lever in N(neutral) or P(park) position.

!!WARNING:
The cooling fan is controlled by en- gine coolant temperature and may sometimes operate even when the engine is not running. Use extremecaution when working near the blades of the cooling fan, so that you are not injured by a rotating fan blade. As theengine coolant temperature decreas- es, the fan will automatically shut off. This is a normal condition. WARNING (
Diesel only):
Never work on injection system withengine running or within 30 seconds after shutting off engine. High pres- sure pump, rail, injectors and highpressure pipes are subjected to high pressure even after the engine has been switched off. The fuel jet pro-duced by fuel leaks may cause seri- ous injury, if it contacts with the body. People using pacemakersshould not move closer than 30cm to the ECU or wiring harness within the engine room with the engine run-ning, since the high currents in the Common Rail system produce con- siderable magnetic fields.
G110D03MC
Fluid level should be within "HOT" range
3. Confirm if the fluid level is in the “HOT” range on the level gauge. If the fluid level is lower, add the speci- fied fluid from the fill hole. If the fluidlevel is higher, drain the fluid from the drain hole.
4. If the fluid level is checked in cold
condition[fluid temperature 20~30°C(68~86°F)], add the fluid to the “COLD” line and then recheck the fluid levelaccording to the above step 2.

G140B01A-AAT Checking the Air Conditioning Operation
1. Start the engine and let it run at afast 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 condi-tioning system inspected by yourHyundai dealer.
G140C01A-AAT Lubrication To lubricate the compressor and the seals in the system, the air conditioning should be run for at least 10 minuteseach week. This is particularly important during cool weather when the air condi- tioning system is not otherwise in use.
! CAUTION:
Running the air conditioning sys- tem for extended periods of time with a low refrigerant level may damage the compressor.
AIR CONDITIONING CARE
G140A01A-AAT Keeping the Condenser Clean The air conditioning condenser (and engine radiator) should be checkedperiodically for accumulation of dirt, dead insects, leaves, etc. These can interfere with maximum cooling effi-ciency. When removing such accumu- lations, brush or hose them away care- fully to avoid bending the cooling fans.CHECKING THE CLUTCH FLUID
G130A01A-AAT (If Installed) To Check the Clutch Fluid The clutch fluid level in the master cylinder should be checked when per- forming other under hood services. Thesystem should be checked for leakage at the same time. Check to make certain that the clutchfluid level is between the "MAX" and "MIN" level markings on the fluid reser- voir. Fill as required. Fluid loss indi-cates a leak in the clutch system which should be inspected and repaired im- mediately. Consult your Hyundai dealer.

4. Replace the blown fuse by pressing
a new fuse of the same rating into place. The fuse should be a snug fit. If it is not, have the fuse clip repaired or replaced by a Hyundai dealer.
1. Turn off the ignition and all other
switches.
2. Open the fuse box and examine each fuse. Remove each fuse bypulling it toward you (a small "fusepuller" tool is contained in the relay and fuse box of the engine room to simplify this operation).
3. Be sure to check all other fuses even if you find one that appears tohave burned out.
G200B02MC
If you do not have a spare fuse, you may be able to borrow a fuse of the same or lower rating from an acces- sory you can temporarily get alongwithout (the radio or cigarette lighter, for example). Always remember to replace the borrowed fuse.
G200B02L
Good B
urned out CAUTION:
A burned-out fuse indicates that there is a problem in the electrical circuit. If you replace a fuse and itblows as soon as the accessory is turned on, the problem is serious and should be referred to a Hyun-dai dealer for diagnosis and repair. Never replace a fuse with anything except a fuse with the same or alower amperage rating. A higher capacity fuse could cause damage and create a fire hazard. NOTE: See page 6-35 for the fuse panel descriptions.

o When lifting a plastic-cased bat-
tery, excessive pressure on the case may cause battery acid to leak, resulting in personal injury.Lift with a battery carrier or with your hands on opposite corners.
o Never attempt to charge the bat-
tery when the battery cables areconnected.
o The electrical ignition system
works with high voltage.Never touch these components with the engine running or the ignition switched on.
CHECKING ELECTRIC COOLING FANS
!
G220B01A-AAT Checking Engine Cooling Fan The engine cooling fan should come on automatically if the engine coolant tem-perature is high. G220C01TB-GAT Checking Condenser Cooling Fan When the air conditioning is in opera- tion, the condenser cooling fan comeson automatically to be controlled by ECU.G220A01A-AAT
WARNING:
The cooling fan is controlled by en- gine coolant temperature and may sometimes operate even when the engine is not running. Use extremecaution when working near the blades of the cooling fan, so that you are not injured by a rotating fanblade. As the engine coolant temper- ature decreases the fan will automat- ically shut off. This is a normal con-dition.
POWER STEERING FLUID LEVEL
G230A01MC-GAT (If Installed) The power steering fluid level should be checked regularly. To check the power steering fluid level,be sure the ignition is "OFF", then check to make certain that the power steering fluid level is between the "MAX"and "MIN" level markings on the fluid reservoir.

25REMOVAL OF WATER FROM THE FUEL FILTER
1JBA7504
G240A01A-AAT POWER STEERING HOSES It is suggested that you check the power steering hose connections for fluid leakage at regular intervals. The power steering hoses should be re-placed if there is severe surface crack- ing, scuffing or worn spots. Deteriora- tion of the hose could cause prema-ture failure. G300A02MC-GAT (DIESEL ENGINE) If the fuel filter warning light illuminates during driving, it indicates that waterhas accumulated in the fuel filter. If this occurs, remove the water as soon as possible. NOTE: It is recommended that water accu- mulated in the fuel filter should be removed by an authorized Hyundaidealer.
NOTE:
o Grinding noise from the power
steering pump may be heard im- mediately after the engine is startedin extremely cold conditions (be- low - 20°C). If the noise stops during warm up, there is no ab-normal function in the system. It is due to a power steering fluid characteristic in extremely coldconditions.
o Do not start the engine when the
power steering oil reservoir isempty.
!WARNING:
Be sure to carefully wipe away any water drained out in this manner, because the fuel mixed in the watermight be ignited and result in a fire. Extracting air in the fuel filter If you drove until you have no fuel left or if you replaced the fuel filter, be sure to extract air in the fuel system as itmakes you difficult to start the engine.
1. Remove the air extract nozzle cap on the fuel filter.
2. Pump up and down until the fuel
flows out of the plug opening.
NOTE:
o Use cloths when you extract air so that the fuel is not sprayed around.
o Clean the fuel around the fuel filter or the injection pump before start- ing the engine to prevent fire.
o Finally, check each part if the fuel is leaking.
