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.
G180A01A-GAT CHECKING BRAKE PEDAL CLEARANCE

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

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
Air pipe
The fuel system should be bled to
remove air as described in the illustra- tion if the fuel supply is exhausted during travel, when the fuel filter is replaced, or if the vehicle is not usedfor a long time.
