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

To Replace the Fluid
Recommended brake fluid conform- ing to DOT 3 or DOT 4 specification should be used. The reservoir cap must be fully tightened to avoid con-tamination from foreign matter or moisture. NOTE: Do not allow any other liquids to contaminate the brake fluid. Sealdamage will result.
WARNING:
Use caution when handling brake fluid. It can damage your vision if you get it in your eyes. It will alsodamage your vehicle's paint if spilled on it and not removed im- mediately.
AIR CONDITIONING CARE
G140A01A-AAT Keeping the Condenser Clean The air conditioning condenser (and engine radiator) should be checked periodically for accumulation of dirt, dead insects, leaves, etc. These caninterfere with maximum cooling effi- ciency. When removing such accu- mulations, brush or hose them awaycarefully to avoid bending the cooling fans. G140B01A-AAT
Checking the Air Conditioning Operation
1. Start the engine and let it run at a
fast idle for several minutes with the air conditioning set at the maxi-mum cold setting.
2. If the air coming out of the in-dash
vents is not cold, have the air con-ditioning system inspected by your Hyundai dealer. G140C01A-AAT Lubrication To lubricate the compressor and the seals in the system, the air condition- ing should be run for at least 10 minutes each week. This is particu-larly important during cool weather when the air conditioning system is not otherwise in use.CAUTION:
Running the air conditioning sys- tem for extended periods of time with a low refrigerant level maydamage the compressor.

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.

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

On the backside of the mult box, you will find a list showing the circuitsprotected by each fuse.If any of your car's lights or otherelectrical 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 that
there 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 6-38 for the fuse panel
descriptions.

G200B01FC
4. Replace the blown fuse by press- ing 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 havea spare fuse, you may be able to borrow a fuse of the same or lower rating from an accessory you cantemporarily get along without (the radio or cigarette lighter, for ex- ample). Always remember to re-place the borrowed fuse.

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.
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 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.!
