Checking the Brake Fluid Level
WARNING:
Use caution when handling brake fluid. It can damage your vision if it gets into your eyes. It will also damage your vehicle's paint ifspilled on it and not removed im- mediately. The level should be between the "MIN" and "MAX" marks on the side of thereservoir. If the level is at or below the "MIN" mark, carefully add fluid to bring it up to "MAX". Do not overfill.

24CHECKING THE CLUTCH FLUID
The system should be checked for leakage at the same time. Check tomake certain that the clutch fluid level is always between the "MAX" and "MIN" level markings on the fluid res-ervoir. Fill as required. Fluid loss indi- cates a leak in the clutch system which should be inspected and re-paired immediately. Consult your Hyundai dealer.

G120E02A-AAT 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

The clutch fluid level in the master
cylinder should be checked when performing other under hood services.

29CHECKING AND REPLACING FUSES
G200A01A-AAT
Replacing a Fusible Link
A fusible link will melt if the electrical
circuits from the battery are ever over- loaded, thus preventing damage to the entire wiring harness. (This could be caused by a short in the systemdrawing too much current.) If this ever happens, have a Hyundai dealer determine the cause, repair the sys-tem and replace the fusible link. The fusible links are located in a fuse box for easy inspection. Good

CAUTION:
When replacing a fusible link, never use anything but a new fusible link with the same or lower amper- age rating. Never use a piece ofwire or a higher-rated fusible link. This could result in serious dam- age and create a fire hazard.

At the scheduled maintenance inspec-
tion, belts should be examined for cracks, wear, fraying or other evi- dence of deterioration and replaced if necessary.
Belt routing should also be checked
to be sure there is no interferencebetween the belts and other parts ofthe engine.
The fuse box for the lights and otherelectrical accessories will be found inthe backside of the multi box located on the instrument panel to the left side of the driver.

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 markingson the fluid reservoir. NOTE: 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 dur- ing warm up, there is no abnormalfunction in the system. It is due to a power steering fluid characteris- tic in extremely cold conditions. Recommended Fluid Use PSF-3 type fluid NOTE: Do not start the engine when the power steering oil reservoir is empty.

CHECKING ELECTRIC COOLING FANS
G220A01A-AAT
WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even whenthe engine is not running. Use extreme caution when working near the blades of the cooling fan,so that you are not injured by a rotating fan blade. As the engine coolant temperature decreases thefan will automatically shut off. This is a normal condition.POWER STEERING FLUID LEVEL

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.
2. Pump the hand pump until there are no more bubbles in the fuel coming out of the air pipe. When doing this, place a cloth around the air pipe to prevent the escapingfuel from spewing about.
3. Replace the air cap when there are no more bubbles in the fuel.
4. Continue pumping until the hand pump becomes stiff.
5. Finally, check to be sure that there
is no leakage of fuel. If in doubt, consult your nearest authorized HYUNDAI dealer. G350B01FC

BLEEDING THE FUEL SYSTEM (Diesel Engine)
The fuel system should be bled to remove air as described in the illus- tration if the fuel supply is exhaustedduring travel, when the fuel filter is replaced, or if the vehicle is not used for a long time.
1. Remove the air cap with pushing the button.

REMOVAL OF WATER FROM THE FUEL FILTER (Diesel Engine)
If the fuel filter warning light illumi- nates during driving, it indicates that water has accumulated in the fuelfilter. If this occurs, remove the water as described.
1. Loosen the drain plug at the bot- tom of the fuel filter.
2. Tighten the drain plug when water no longer comes out.
3. Check to be sure that the warning lamp illuminates when the ignition key is turned to "ON", and that it goes off when the engine is started. If in doubt, consult your nearest authorized HYUNDAI dealer.
NOTE: It is recommended that water ac-
cumulated in the fuel filter should be removed by an authorized Hyundai dealer. G300B02FC
!WARNING:
o Do not smoke or have any other open flame near the vehicle while bleeding the fuel system.
o Be sure to carefully wipe away
any water drained out in thismanner, because the fuel mixed in the water might be ignited and result in a fire.

EMISSION CONTROL SYSTEMS
3CATALYTIC CONVERTER
H020A01A-GAT
(If Installed) ; For a gasoline engine
HFC5013
The catalytic converter is part of the
exhaust emission control system. Its purpose is to remove certain engine emission products from the engine'sexhaust. It looks something like a muffler and is located underneath the car in the exhaust system.
Catalytic Converter H020B01A-GAT
About the Catalytic Converter
Exhaust gases passing through the
catalytic converter cause it to operate at very high temperatures. As a re- sult, the introduction of large amounts of unburned gasoline may cause it tooverheat and create a fire hazard. This can be avoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good con- dition. Extremely high converter temperatures can result from im-proper operation of the electrical, ignition or fuel injection systems. o If your engine stalls, pings, knocks,
or is hard to start, take your car to your Hyundai dealer as soon as possible and have the difficulty corrected.
o Avoid driving with a very low fuel level. If your run out of gasoline, itcould cause the engine to misfireand result in excessive loading of the catalytic converter.
o Avoid idling the engine for periods longer than 10 minutes.
o Your Hyundai should not be either pushed or pulled to get it started.This can cause the catalytic con- verter to overload.
o Take care not to stop your Hyundai
over any combustible material suchas grass, paper, leaves or rags. As these materials could come in con- tact with the catalytic converter andcould cause a fire.
o Do not touch the catalytic con-
verter or any other part of the ex-haust system while the engine is running as it is very hot and could result in burns.
o Remember that your Hyundai
dealer is your best source of assis-tance.
H020D01S-GAT
; For a diesel engine
All Hyundai vehicles are equipped
with oxidation type catalytic converter to reduce the carbon monoxide, hy- drocarbons and particulate containedin the exhaust gas.
