15CHECKING THE TRANSAXLE FLUID (AUTOMATIC)
G110A01MC-AAT Transaxle fluid in the automatic transaxle should be checked at those intervals specified in the vehicle main- tenance schedule in Section 5. NOTE: Automatic transaxle fluid is basi- cally a red color. As driving distance increases, the fluid color turns dark-ish red gradually. It is normal condi- tion and you should not judge the need to replace based upon thechanging color. You must replace the automatic transaxle fluid in accordance withintervals specified in the vehicle maintenance schedule in section 5.
!WARNING:
The transaxle fluid level should be checked when the engine is at nor- mal operating temperature. This means that the engine, radiator,exhaust system etc., are very hot. Exercise great care not to burn your- self during this procedure. G110D02A-GAT To Check the Transaxle Fluid Level Park the car on level ground with the parking brake engaged. When thetransaxle fluid level is checked, the transaxle fluid should be at normal operating temperature and the engineidling. While the engine is idling, apply the brakes and move the gear selectorlever from "P" to each of its other positions -- "R", "N", "D", "2", "L" -- and then return to "N" or "P". With theengine still idling:

3. If the transaxle fluid level is low, use
a funnel to add transaxle fluid through the dipstick tube until the levelreaches the "HOT" range. Do not overfill.
WARNING:
The cooling fan is controlled by en- gine coolant temperature and maysometimes operate even when the engine is not running. Use extreme caution when working near the bladesof the cooling fan, so that you are not injured by a rotating fan blade. As the engine coolant temperature decreas-es, the fan will automatically shut off. This is a normal condition. WARNING (
Diesel only):
Never work on injection system with engine running or within 30 seconds after shutting off engine. High pres- sure pump, rail, injectors and highpressure pipes are subjected to high pressure even after the engine has been switched off. The fuel jet pro-duced by fuel leaks may cause seri- ous injury, if it contacts with the body. People using pacemakersshould not move closer than 30cm to the ECU or wiring harness within the engine room with the engine run-ning, since the high currents in the Common Rail system produce con- siderable magnetic fields.
G110D03MC
Fluid level should be within "HOT" range
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. G110D02MC

G140B01A-AAT Checking the Air Conditioning Operation
1. Start the engine and let it run at afast idle for several minutes with the air conditioning set at the maximum cold setting.
2. If the air coming out of the in-dash vents is not cold, have the air condi-tioning system inspected by yourHyundai dealer.
G140C01A-AAT Lubrication To lubricate the compressor and the seals in the system, the air conditioning should be run for at least 10 minuteseach week. This is particularly important during cool weather when the air condi- tioning system is not otherwise in use.
! CAUTION:
Running the air conditioning sys- tem for extended periods of time with a low refrigerant level may damage the compressor.
AIR CONDITIONING CARE
G140A01A-AAT Keeping the Condenser Clean The air conditioning condenser (and engine radiator) should be checkedperiodically for accumulation of dirt, dead insects, leaves, etc. These can interfere with maximum cooling effi-ciency. When removing such accumu- lations, brush or hose them away care- fully to avoid bending the cooling fans.CHECKING THE CLUTCH FLUID
G130A01A-AAT (If Installed) To Check the Clutch Fluid The clutch fluid level in the master cylinder should be checked when per- forming other under hood services. Thesystem should be checked for leakage at the same time. Check to make certain that the clutchfluid level is between the "MAX" and "MIN" level markings on the fluid reser- voir. Fill as required. Fluid loss indi-cates a leak in the clutch system which should be inspected and repaired im- mediately. Consult your Hyundai dealer.

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 fuse clip repaired or replaced by a Hyundai dealer.
1. Turn off the ignition and all other
switches.
2. Open the fuse box and examine each fuse. Remove each fuse bypulling it toward you (a small "fusepuller" tool is contained in the relay and fuse box of the engine room to simplify this operation).
3. Be sure to check all other fuses even if you find one that appears tohave burned out.
G200B02MC
If you do not have a spare fuse, you may be able to borrow a fuse of the same or lower rating from an acces- sory you can temporarily get alongwithout (the radio or cigarette lighter, for example). Always remember to replace the borrowed fuse.
G200B02L
Good B
urned out CAUTION:
A burned-out fuse indicates that there is a problem in the electrical circuit. If you replace a fuse and itblows as soon as the accessory is turned on, the problem is serious and should be referred to a Hyun-dai dealer for diagnosis and repair. Never replace a fuse with anything except a fuse with the same or alower amperage rating. A higher capacity fuse could cause damage and create a fire hazard. NOTE: See page 6-35 for the fuse panel descriptions.

CHECKING THE BATTERY
G210A01A-AAT
WARNING:
Batteries can be dangerous! When working with batteries, carefully ob-serve the following precautions to avoid serious injuries. The fluid in the battery contains a strong solution of sulfuric acid, which is poi- sonous and highly corrosive. Be careful not to spill it on yourself or the car. If youdo spill battery fluid on yourself, imme- diately do the following:

o When lifting a plastic-cased bat-
tery, excessive pressure on the case may cause battery acid to leak, resulting in personal injury.Lift with a battery carrier or with your hands on opposite corners.
o Never attempt to charge the bat-
tery when the battery cables areconnected.
o The electrical ignition system
works with high voltage.Never touch these components with the engine running or the ignition switched on.
CHECKING ELECTRIC COOLING FANS
!
G220B01A-AAT Checking Engine Cooling Fan The engine cooling fan should come on automatically if the engine coolant tem-perature is high. G220C01TB-GAT Checking Condenser Cooling Fan When the air conditioning is in opera- tion, the condenser cooling fan comeson automatically to be controlled by ECU.G220A01A-AAT
WARNING:
The cooling fan is controlled by en- gine coolant temperature and may sometimes operate even when the engine is not running. Use extremecaution when working near the blades of the cooling fan, so that you are not injured by a rotating fanblade. As the engine coolant temper- ature decreases the fan will automat- ically shut off. This is a normal con-dition.
POWER STEERING FLUID LEVEL
G230A01MC-GAT (If Installed) 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 between the "MAX"and "MIN" level markings on the fluid reservoir.

25REMOVAL OF WATER FROM THE FUEL FILTER
1JBA7504
G240A01A-AAT POWER STEERING HOSES It is suggested that you check the power steering hose connections for fluid leakage at regular intervals. The power steering hoses should be re-placed if there is severe surface crack- ing, scuffing or worn spots. Deteriora- tion of the hose could cause prema-ture failure. G300A01MC-GAT (DIESEL ENGINE) If the fuel filter warning light illuminates during driving, it indicates that waterhas accumulated in the fuel filter. If this occurs, remove the water as soon as possible. NOTE: It is recommended that water accu- mulated in the fuel filter should be removed by an authorized Hyundaidealer.
NOTE:
o Grinding noise from the power
steering pump may be heard im- mediately after the engine is startedin extremely cold conditions (be- low - 20°C). If the noise stops during warm up, there is no ab-normal function in the system. It is due to a power steering fluid characteristic in extremely coldconditions.
o Do not start the engine when the
power steering oil reservoir isempty.
!WARNING:
Be sure to carefully wipe away any water drained out in this manner, because the fuel mixed in the watermight be ignited and result in a fire.
