CHECKING DRIVE BELTS (Gasoline Engine)
Drive belts should be checked periodically for
proper tension and adjusted if necessary. At the same time, belts should be examined for cracks,wear, fraying or other evidence of deteriorationand replaced if necessary.
Belt routing should also be checked to be sure
there is no interference between the belts andother parts of the engine. After a belt is re-placed, the new belt should be adjusted againafter two or three weeks to eliminate slackresulting from initial stretching after use.

CHECKING AND REPLACING FUSES Replacing a Fusible Link
A fusible link will melt if the electrical circuits
from the battery are ever overloaded, thus pre- venting 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 system and replace the fusible link.The fusible links are located in a fuse box foreasy inspection.
CAUTION: When replacing a fusible link, never use
anything but a new fusible link with the same or lower amperage rating. Never use apiece of wire or a higher-rated fusible link.This could result in serious damage andcreate a fire hazard.

6-20 CAUTION: A burned-out fuse indicates that there is aproblem in the electrical circuit. If you re-place a fuse and it blows as soon as theaccessory is turned on, the problem is seri-ous and should be referred to a Hyundaidealer for diagnosis and repair. Never re-place a fuse with anything except a fusewith the same or a lower amperage rating. Ahigher capacity fuse could cause damageand create a fire hazard.

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 fuseclip repaired or replaced by a Hyundai dealer.If you do not have a spare fuse, you may beable to borrow a fuse of the same or lowerrating from an accessory you can tempo-rarily get along without (the radio or cigarettelighter, for example). Always remember toreplace the borrowed fuse.

Replacing Accessory Fuse The fuse box for the lights and other electrical accessories will be found in the backside of multibox located in the left side of driver. Inside the boxyou will find a list showing the circuits protectedby each fuse. If any of your car’s lights or other electrical
accessories stop working, a blown fuse couldbe the reason. If the fuse has burned out, youwill see that the metal strip inside the fuse hasburned through. If you suspect a blown fuse,follow this procedure:
HFC4010
NOTE: See page 6-26 for the fuse panel descrip-
tions. 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 thefuse box to simplify this operation).
3. Be sure to check all other fuses even if you find one that appears to have burned out.

CHECKING THE BATTERY
WARNING: Batteries can be dangerous! When working
with batteries, carefully observe the follow- ing precautions to avoid serious injuries.
The fluid in the battery contains a strong solu-
tion of sulfuric acid, which is poisonous andhighly corrosive. Be careful not to spill it onyourself or the car. If you do spill battery fluid onyourself, immediately do the following:
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 get medical assistanceas soon as possible. While you are beingdriven to get medical assistance, continueto rinse your eyes by using a sponge or softcloth saturated with water.

G220A01A-AAT
CHECKING ELECTRIC COOLING FANS WARNING: The cooling fan is controlled by engine cool- ant temperature and may sometimes oper-ate even when the engine is not running.Use extreme caution when working near theblades of the coolant fan, so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases the fanwill automatically shut off. This is a normalcondition. G220B01A-AAT
Checking Engine Cooling Fan The engine coolant fan should come on auto- matically if the engine coolant temperature ishigh. G220C01A-AAT
Checking Condenser Cooling Fan The condenser coolant fan should come on automatically whenever the air conditioning isin operation.
G210B01A-AAT
Checking the Battery Keep the battery clean. Any evidence of corro-
sion around the battery posts or terminals shouldbe removed using a solution of household bak-ing soda and warm water. After the batteryterminals are dry, cover them with a light coat-ing of grease.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk ofmagnesia, eat a raw egg or drink vegetableoil. Get medical assistance as soon aspossible.
While batteries are being charged (either by abattery charger or by the vehicle’s alternator),they produce explosive gases. Always observethese warnings to prevent injuries from occur-ring:
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.

POWER STEERING HOSES
It is suggested that you check the power steer-
ing hose connections for fluid leakage at regular intervals. The power steering hoses should bereplaced if there is severe surface cracking,scuffing or worn spots. Deterioration of thehose could cause premature failure. NOTE: Grinding noise from the power steering
pump may be heard immediately after the engine is started in extremely cold condi-tions (below - 20°C). If the noise stops dur-ing warm up, there is no abnormal functionin the system. It is due to a power steeringfluid characteristic in extremely cold condi-tions.
Recommended Fluid Use PSF-3 type fluid NOTE: Do not start the engine when the power
steering oil reservoir is empty. G300A01B-GAT
REMOVAL OF WATER FROM THE FUEL FILTER (DIESEL ENGINE)
If the fuel filter warning light illuminates during driving, it indicates that water has accumulatedin the fuel filter. If this occurs, remove the wateras described below.
