CHECKING DRIVE BELTS
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 of deterioration and replaced if neces- sary. Belt routing should also be checked to be sure there is no interference between the belts and other parts ofthe engine. After a belt is replaced, the new belt should be adjusted again after two or three weeks to eliminateslack resulting from initial stretching after use. G140D01L

CHECKING AND REPLACING FUSES Replacing a Fusible Link
A fusible link will melt if the electrical circuits from the battery are ever over- loaded, thus preventing damage tothe entire wiring harness. (This could be caused by a short in the system drawing too much current.) If thisever happens, have a Hyundai dealer determine the cause, repair the sys- tem and replace the fusible link. Thefusible links are located in a under hood junction box for easy inspec- tion. G200A01L

CHECKING THE BATTERY
WARNING:
Batteries can be dangerous! When working with batteries, care-
fully observe the following pre- cautions to avoid serious injuries.
The fluid in the battery contains a
strong solution of sulfuric acid, whichis poisonous and highly corrosive. Be careful not to spill it on yourself or thecar. If you do spill battery fluid on yourself, 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 driven to get medical assistance, continueto rinse your eyes by using a sponge or soft cloth saturated with water. o If you swallow battery fluid, drink a
large quantity of water or milk fol-lowed by milk of magnesia, eat araw egg or drink vegetable oil. Get medical assistance as soon as pos- sible.
While batteries are being charged(either by a battery charger or by the vehicle's generator), they produce explosive gases. Always observethese warnings to prevent injuries from occurring:
o Charge batteries only in a well ven- tilated area.
o Do not permit flames, sparks or
smoking in the area.
o Keep children away from the area. G210B01A-AAT 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 terminals are dry, cover them with a light coating of grease.

CHECKING ELECTRIC COOL- ING FANS
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 coolant temperature decreases the fan willautomatically shut off. This is a normal condition.
G220B01A-AAT
Checking Engine Cooling Fan
The engine cooling fan should come
on automatically if the engine coolanttemperature is high.
G220C01A-AAT
Checking Condenser Cooling Fan
The condenser cooling fan should
come on automatically whenever the air conditioning is in operation.

POWER STEERING HOSES
It is suggested that you check the power steering hose connections forfluid leakage at regular intervals.The power steering hoses should bereplaced if there is severe surface cracking, scuffing or worn spots. De- terioration of the hose could causepremature failure.
G230A03A-GAT POWER STEERING FLUID LEVEL
HXG2006
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 betweenthe "MAX" and "MIN" level markings on the fluid reservoir. NOTE: Grinding noise from the power steering pump may be heard im-mediately after the engine is started in extremely cold conditions (be- low - 20°C). In this case, if the noise stops during warm up, there is no abnormal function in the sys- tem. This is due to a power steer-ing fluid characteristic 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.
