While the engine is idling, apply the brakes and
move the gear selector lever from "P" to each of its other positions — "R", "N", "D" — andthen return to "N" or "P". With the engine stillidling:
1. Open the hood, being careful to keep hands, long hair and clothing clear of any moving parts.
2. Remove the transaxle dipstick, wipe it clean, reinsert the dipstick as far as it will go, thenremove it again. Now check the fluid level onthe dipstick. It should be in the "HOT" rangeon the dipstick.
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipsticktube until the level reaches the "HOT" range.Do not overfill. 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 cooling 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. Fluid level should be within this range

AIR CONDITIONING CARE Keeping the Condenser Clean
The air conditioning condenser (and engine radiator) should be checked periodically foraccumulation of dirt, dead insects, leaves, etc.These can interfere with maximum cooling effi-ciency. When removing such accumulations,brush or hose them away carefully to avoidbending the cooling fans.
G120D01A-AAT
To Check the Fluid Level
The fluid level in the brake fluid reservoir should
be checked periodically. The level should be between the "MIN" and "MAX" marks on theside of the reservoir. If the level is at or belowthe "MIN" mark, carefully add fluid to bring it upto "MAX". Do not overfill.
G120E02A-AAT
Adding Brake Fluid WARNING: Handle brake fluid carefully. It can damage your vision if it gets into your eyes. Use onlyDOT 3 or DOT 4 specification fluid from asealed container. Do not allow the fluid canor reservoir to remain open any longer thanrequired. This will avoid entry of dirt andmoisture which can damage the brake sys-tem and cause improper operation. To add brake fluid, first wipe away any dirt thenunscrew the fluid reservoir cap. Slowly pour therecommended fluid into the reservoir. Do notoverfill. Carefully replace the cap on the reser-voir and tighten. G130A01S-AAT
CHECKING THE CLUTCH FLUID (Manual Transaxle)To Check the Clutch Fluid
The clutch fluid level in the master cylinder should be checked when performing other un-der hood services. The system should bechecked for leakage at the same time.

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.

G200B02A-AAT
Replacing Accessory Fuse The fuse box for the lights and other electrical accessories will be found low on the dashboardon the driver's side. Inside the box you will find alist showing the circuits protected by 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:
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 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 relay 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.

DO-IT-YOURSELF MAINTENANCE 6-19
CAUTION: A burned-out fuse indicates that there is a
problem 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.
NOTE: See page 6-23 for the fuse panel descrip-
tions.

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.
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 a
battery charger or by the vehicle's alternator),they produce explosive gases. Always observethese warnings to prevent injuries from occur-ring: 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.
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 cool-ant temperature decreases the fan will auto-matically shut off. This is a normal condi-tion.
G220B01A-AAT
Checking Engine Cooling Fan The engine coolant fan should come on auto-
matically if the engine coolant temperature ishigh.
o Charge batteries only in a well ventilated
area.
o Do not permit flames, sparks or smoking in the area.
