WHAT TO DO IN AN EMERGENCY
3-8 D080A02A-GAT IF YOUR CAR MUST BE TOWED CAUTION: Your car can be damaged if towed incorrect- ly! If your car has to be towed, it should be done by your Hyundai dealer or a commercial tow truck service. This will help assure that your car is not damaged in towing. Also, professionals are gen- erally aware of local laws governing towing. In any case, rather than risk damage to your car, it is suggested that you show this information to the tow truck operator. Be sure that a safety chain system is used and that all local laws are ob- served.
D080B01A-AAT Towing a Car with a Manual Transaxle
o If the car is being towed with the rear wheels
on the ground, be sure the parking brake is released.
o If the car is being towed with the front wheels on the ground, be sure that the transaxle is in neutral. Also, be sure that the ignition key is in the "ACC" position. This is necessary to prevent damage to the steering lock mecha- nism, which is not designed to hold the front wheels straight while the car is being towed.
o If any of the loaded wheels or suspension
components are damaged, a towing dolly must be used.

D060J01FC-GAT After Changing Wheels If you have a tire gauge, remove the valve cap and check the air pressure. If the pressure is lower than recommended, drive slowly to the nearest service station and inflate to the correct pressure. If it is too high, adjust it until it is correct. Always reinstall the valve cap after checking or adjusting tire pressure. If the cap is not replaced, air may leak from the tire. If you lose a valve cap, buy another and install it as soon as possible. After you have changed wheels, always secure the flat tire in its place in the luggage room and return the jack and tools to their proper storage locations.

VEHICLE MAINTENANCE REQUIREMENTS
5- 6
F060A01A-AAT EXPLANATION OF SCHEDULED MAINTENANCE ITEMS F060M01A-AAT o Engine Oil and FilterThe engine oil and filter should be changed at
the intervals specified in the maintenance sched- ule. If the car is being driven in severe condi- tions, more frequent oil and filter changes are required. F060B01A-AAT
o Drive BeltsInspect all drive belts for evidence of cuts, cracks, excessive wear or oil saturation and replace if necessary. Drive belts should be checked periodically for proper tension andadjusted as necessary. F060C01A-AAT
o Fuel FilterA clogged filter can limit the speed at which the vehicle may be driven, damage the emission system and cause hard starting. If an exces- sive amount of foreign matter accumulates in the fuel tank, the filter may require replacement more frequently. After installing a new filter, run the engine for several minutes, and check for leaks at the connections. Fuel filters should be installed by trained technicians.
F060D02A-AAT
o Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and connec- tions for leakage and damage. Have a trained technician replace any damaged or leaking parts immediately. 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 after the engine stopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers should not move than 30cm closer to the ECU or wiring har- ness within the engine room while engine is running, since the high currents in the Com- mon Rail system produce considerable mag- netic fields. F060E01A-AAT
o Timing BeltInspect all parts related to the timing belt for damage and deformation. Replace any dam- aged parts immediately. F060G01A-AAT
o Vapor Hose and Fuel Filler Cap The vapor hose and fuel filler cap should be
inspected at those intervals specified in themaintenance schedule. Make sure that a new vapor hose or fuel filler cap is correctly re- placed.
F060F01A-AAT
o Vacuum, Crankcase Ventilation
Hoses
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and brit-tle rubber, cracking, tears, cuts, abrasions, and excessive swelling indicate deterioration. Par- ticular attention should be paid to examining those hose surfaces nearest to high heat sourc- es, such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heatsource, sharp edges or moving component which might cause heat damage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make sure they are secure, and that no leaks are present. Hoses should be replaced immediately if there is any evidence of deterioration or damage.

To Check the Coolant Level
G050C01FC
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool- ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cold.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect for G050D02A-AAT
To Change the Coolant The coolant should be changed at those inter-
vals specified in the vehicle maintenance sched-ule in Section 5.
CAUTION: Engine coolant can damage the finish of
your car. If you spill engine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park- ing brake and remove the radiator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer’s directions on the enginecoolant container, add the appropriate quan-tity of coolant to the radiator.

To Check the Maunal Transaxle Fluid Level
SSA6100B
Park the car on level ground with the engine off.
1. Using a wrench of the correct size, loosen the oil filler plug by turning it counterclock- wise and remove it with your fingers.
2. Use your finger or suitable tool to feel inside the hole. The oil level should be at its bottomedge. If it is not, check for leaks beforeadding oil. To refill the transaxle or bring theoil level up,add oil slowly until it reaches theproper level. Do not overfill. G110A01A-AAT
CHECKING THE TRANSAXLE FLUID (AUTOMATIC)
Transaxle fluid in the automatic transaxle should be checked at those intervals specified in thevehicle maintenance schedule in Section 5. G110B03A-AAT
Recommended Fluid Your Hyundai automatic transaxle is specially designed to operate with DIAMOND ATF SP- III
or SK ATF SP- III. Damage caused by a
nonspecified fluid is not covered by your newvehicle limited warranty. G110C01FC-GAT
Transaxle Fluid Capacity
The fluid capacity of the automatic transaxle is
6.1 liters (1.6 DOHC)/6.7 liters (1.8 DOHC).
WARNING: The transaxle fluid level should be checked
when the engine is at normal operating tem- perature. This means that the engine, radia-tor, exhaust system etc., are very hot. Exer-cise great care not to burn yourself duringthis procedure.
Filler plugG110A01E
Transaxle lubricant in the manual transaxle should
be checked at those intervals specified in the vehicle maintenance schedule in Section 5. Recommended Oil

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. WARNING (Diesel only): Never work on injection system with engine running or within 30 seconds after shuttingoff engine. High pressure pump, rail, injec-tors and high pressure pipes are subject tohigh pressure even after the engine stopped.The fuel jet produced by fuel leaks maycause serious injury, if it touch the body.People using pacemakers should not movethan 30cm closer to the ECU or wiring har-ness within the engine room while engine isrunning, since the high currents in the Com-mon Rail system produce considerable mag-netic fields.
