G190A01A-GAT Gasoline Engine Drive belts should be checked peri- odically for proper tension and ad-justed if necessary. At the same time, belts should be examined for cracks, wear, fraying or other evidence ofdeterioration and replaced if neces- sary. Belt routing should also be checked to be sure there is no interference between the belts and other parts of the engine. After a belt is replaced,the new belt should be adjusted again after two or three weeks to eliminate slack resulting from initial stretchingafter use.

28CHECKING 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, neveruse 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 other
electrical accessories will be found inthe backside of the multi box located on the instrument panel to the left side of the driver.

On the backside of the mult box, you
will find a list showing the circuits protected by each fuse. If any of your car's lights or other
electrical accessories stop working, ablown fuse could be the reason. If the fuse has burned out, you will see that the metal strip inside the fuse hasburned through. If you suspect a blown fuse, follow this procedure:
1. Turn off the ignition and all other switches.
2. Open the fuse box and examine
each fuse. Remove each fuse by pulling it toward you (a small "fuse puller" tool is contained in the fuse box to simplify this operation).
3. Be sure to check all other fuses even if you find one that appears tohave burned out. Good
G200B03Y
Burned out
CAUTION:
A burned-out fuse indicates thatthere is a problem in the electrical circuit. If you replace a fuse and it blows as soon as the accessory isturned on, the problem is serious and should be referred to a Hyundai dealer for diagnosis andrepair. Never replace a fuse with anything except a fuse with the same or a lower amperage rating.A higher capacity fuse could cause damage and create a fire hazard. NOTE: See page 6-39 for the fuse panel descriptions.
!
G200B01FC
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. If you do not have a sparefuse, you may be able to borrow a fuse of the same or lower rating from an accessory you can tempo-rarily get along without (the radio or cigarette lighter, for example). Al- ways remember to replace the bor-rowed fuse.

The fluid in the battery contains a
strong solution of sulfuric acid, which is poisonous and highly corrosive. Be careful not to spill it on yourself or the car. If you do spill battery fluid onyourself, immediately do the follow- ing:
o If battery fluid is on your skin, flush
the affected areas with water for at least 15 minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your eyes with water and getmedical assistance as soon as possible. While you are being drivento get medical assistance, continue to rinse your eyes by using a sponge or soft cloth saturated withwater.
o If you swallow battery fluid, drink a large quantity of water or milk fol- lowed by milk of magnesia, eat a raw egg or drink vegetable oil. Getmedical assistance as soon as possible. While batteries are being charged (either by a battery charger or by thevehicle's alternator), they produce explosive gases. Always observe these warnings to prevent injuries fromoccurring:
o Charge batteries only in a well ventilated area.
o Do not permit flames, sparks or smoking in the area.
o Keep children away from the area.

Checking the Battery
Keep the battery clean. Any evidence of corrosion around the battery posts or terminals should be removed using a solution of household baking sodaand warm water. After the battery ter- minals are dry, cover them with a light coating of grease.
WARNING:Always read the followinginstructions carefully whenhandling a battery.Keep lighted cigarettes andall other flames or sparksaway from the battery.Hydrogen, which is a highlycombustible gas, is always present in battery cells and may explode if ignited.Keep batteries out of the reach of children becausebatteries contain highly cor- rosive SULFURIC ACID. Do not allow battery acid tocontact your skin, eyes, clothing or paint finish. If any electrolyte gets into your eyes, flush your eyes with clean water for at least15 minutes and get imme- diate medical attention. If possible, continue to applywater with a sponge or cloth until medical atten- tion is received. If electrolyte gets on your skin, thoroughly wash the contacted area.If you feel a pain or a burn-ing sensation, get medicalattention immediately.Wear eye protection whencharging or working near abattery.Always provide ventilationwhen working in an en- closed space.o When lifting a plastic-cased bat- tery, excessive pressure on the case may cause battery acid toleak, 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.

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 escaping fuel from spew-ing 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
