Recommended Fluid
Your Hyundai automatic transaxle is
specially designed to operate with HYUNDAI GENUINE ATF SP III, DIA- MOND ATF SP-III, SK ATF SP III orother brands approved by Hundai Motor Co,. Damage caused by a nonspecified fluid is not covered byyour new vehicle limited warranty. NOTE: Automatic transaxle fluid is a red in
color. As driving distance increases, the fluid color turns darkish red gradually. It is a normal condition and you should not judge the needto replace based upon the changing color.
You must replace the automatic
transaxle fluid in accordance withintervals specified in the vehicle maintenance schedule in section5.
!WARNING:
It is always better to check the
transaxle oil level when the engine is cool or cold. If the engine is hot, you should exercise great cautionto avoid burning yourself on hot engine or exhaust parts.

G110D03E-GAT
To Check the Transaxle Fluid Level
Park the car on level ground with the
parking brake engaged. When the transaxle fluid level is checked, the transaxle fluid should be at normaloperating temperature and the en- gine idling.
G110C01E-GAT
Transaxle Fluid Capacity
The fluid capacity of the automatic
transaxle is 6.1 liters (1.6 DOHC)/7.8 liters (1.8/2.0 DOHC). 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", "3" (1.8/2.0 DOHC), "2", "L" -- and then return to"N" or "P". With the engine still idling:
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 faras it will go, then remove it again.Now check the fluid level on the dipstick. It should be in the "HOT" range on the dipstick. G110D01E
!WARNING:
The transaxle fluid level should be
checked when the engine is at normal operating temperature. This means that the engine, radiator,exhaust system etc., are very hot. Exercise great care not to burn yourself during this procedure.
! CAUTION:
Use of aftermarket ATF additives
may cause damage to the auto- matic transaxle. Only use HYUNDAI GENUINE ATF SP III, DIAMOND ATF SP III, SK ATF SP III or otherbrands approved by Hyundai Mo- tor Co., If you are having your vehicle serviced at a facility otherthan a Hyundai dealer, verify that the correct ATF is used for your vehicle.

CHECKING THE BRAKES
G120A01A-AAT
! CAUTION:
Because brakes are essential to
the safe operation of the car, it is suggested that they be checked and inspected by your Hyundai dealer. The brakes should bechecked and inspected for wear at those intervals specified in the vehicle maintenance schedule inSection 5.
WARNING (Diesel only):
Never work on injection system
with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec-tors and high pressure pipes are subject to high pressure even af- ter the engine stopped. The fuel jetproduced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers shouldnot move than 30cm closer to the ECU or wiring harness within the engine room while engine is run-ning, since the high currents in the Common Rail system produce considerable magnetic fields.
WARNING:
The cooling fan is controlled byengine coolant temperature and may sometimes operate even when the engine is not running. Useextreme caution when working near the blades of the cooling fan so that you are not injured by arotating fan blade. As the engine coolant temperature decreases, the fan will automatically shut off. Thisis a normal condition.
HKSOM120
Fluid level should be within this range
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipstick tube until the level reaches the "HOT" range. Do not overfill.

Adding Brake Fluid
G120C02A-AAT
Recommended Brake Fluid
Use only hydraulic brake fluid con- forming to DOT 3 or DOT 4 specifica- tions in your braking system. Follow the instructions printed on the con-tainer. G120D01A-AAT
To Check the Fluid Level
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.
G120B01A-AAT
Checking the Brake Fluid Level
WARNING:
Use caution when handling brakefluid. It can damage your vision ifit gets into your eyes. It will also damage your vehicle's paint if spilled on it and not removed im-mediately.
HXDFL012
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 cap on the reservoir and tighten.
The fluid level in the brake fluid reser-
voir should be checked periodically.The level should be between the "MIN" and "MAX" marks on the side of the reservoir. If the level is at or belowthe "MIN" mark, carefully add fluid to bring it up to "MAX". Do not overfill.

26CHECKING THE CLUTCH FLUID
!
G130B02A-AAT
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. Seal damage will result.
WARNING:
Use caution when handling brake
fluid. It can damage your vision ifyou get it in your eyes. It will alsodamage your vehicle's paint if spilled on it and not removed im- mediately.
The clutch fluid level in the mastercylinder should be checked whenperforming other under hood services. 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.

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.
! G140D01S-GAT
Checking the Compressor Drive Belt When the air conditioning is being used regularly, the compressor drive belt tension should be checked at least once a month.To check the drive belt tension, pressdown on the belt halfway between theengine crankshaft and compressor pulleys. Pressing with your finger, you should not be able to deflect this beltanymore than 8.0 mm. If you have the instruments to check it with a force of 98N (22 lb.), the deflectionshould be approx. 8.0 mm (0.315 in.). If the belt is too loose, have it ad- justed by your Hyundai dealer.

31CHECKING 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

G200B01E-AAT
Replacing Accessory Fuses
HXDFL200
CAUTION:
When replacing a fusible link, never
use anything but a new fusible link with the same or lower amper- age rating. Never use a piece ofwire or a higher-rated fusible link. This could result in serious dam- age and create a fire hazard.
! The fuse box for the lights and other electrical accessories will be found inthe backside of multi box located in the left side of the driver. On the backside of the multi box, you will finda list showing the circuits protected by each fuse. If any of your car's lights or other electrical accessories stop working, a blown fuse could be the reason. If the fuse has burned out, you will see thatthe metal strip inside the fuse has burned 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 fusebox to simplify this operation).
3. Be sure to check all other fuses
even if you find one that appears tohave burned out.
