SPARE TIRE
WARNING (Diesel Only):
Never work on injection system with engine running or within 30 sec- onds after shutting off engine. High pressure pump, rail, injectors andhigh pressure pipes are subject to high pressure even after the engine stopped. The fuel jet produced byfuel leaks may cause serious in- jury, if it touch the body. People using pacemakers should not movethan 30cm closer to the ECU or wiring harness within the engine room while engine is running, sincethe high currents in the Common Rail system produce considerable magnetic fields. WARNING:
Do not remove the radiator cap whenthe engine is hot. This can allowcoolant to be blown out of the open- ing and cause serious burns.
6. If you cannot find the cause of the overheating, wait until the engine temperature has returned to nor-mal. Then, if the engine coolant has been lost, carefully add coolant to the reservoir (Page 6-11) to bring thefluid level in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert
for further signs of overheating. Ifoverheating happens again, call a Hyundai dealer for assistance.

5. If the water pump drive belt is broken
or coolant is leaking out, stop the engine immediately and call the near- est Hyundai dealer for assistance. D040A03A-GAT The following instructions for the FULL SIZE spare tire should be observed: Check inflation pressure as soon as practical after installing the spare tire, and adjust to the specified pressure. The tire pressure should be periodi-cally checked and maintained at the specified pressure while the tire is stored.
CAUTION:
Serious loss of engine coolant indi-cates there is a leak in the coolingsystem and this should be checked as soon as possible by a Hyundai dealer. Spare Tire Pressure

D060J01E-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 recom- mended, drive slowly to the nearestservice station and inflate to the cor- rect pressure. If it is too high, adjust it until it is correct. Always reinstall thevalve cap after checking or adjusting tire pressure. If the cap is not replaced,

air may leak from the tire. If you lose avalve cap, buy another and install it assoon as possible. After you have changed wheels, al- ways secure the flat tire in its place inthe trunk and return the jack and tools to their proper storage locations.

EMERGENCY COMMODITY
D070A01A-GAT (If Installed) There are some emergency commodi- ties in the vehicle to help you respond to the emergency situation. Fire Extinguisher The fire extinguisher is located under the front passenger seat. I110B01JM

EXPLANATION OF SCHED- ULED MAINTENANCE ITEMS
F060M01A-AAT
o Engine Oil and Filter The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the car is being driven in severe conditions,more frequent oil and filter changes are required. F060B01A-AAT
o Drive Belts Inspect all drive belts for evidence of cuts, cracks, excessive wear or oil saturation and replace if necessary. Drive belts should be checked period-ically for proper tension and adjusted as necessary. F060C01A-AAT
o Fuel Filter
A clogged filter can limit the speed at
which the vehicle may be driven, dam-age the emission system and cause hard starting. If an excessive amountof foreign matter accumulates in the fuel tank, the filter may require re- placement more frequently. After installing a new filter, run the
engine for several minutes, and checkfor leaks at the connections. Fuel fil- ters should be installed by trained technicians. F060D01TB-GAT
o Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and connections for leakage and damage. Have a trained technician replace any damaged or leaking parts immedi-ately.
WARNING (Diesel only):
Never work on injection system with
engine running or within 30 sec-onds after shutting off engine. High pressure pump, rail, injectors and high pressure pipes are subjectedto high pressure even after the en- gine has been switched off. The fuel jet produced by fuel leaks maycause serious injury, if it contacts with the body. People using pace- makers should not move closerthan 30cm to the ECU or wiring harness within the engine room with the engine running, since the highcurrents in the Common Rail sys- tem produce considerable magnetic fields.

F060H01A-AAT
o Air Cleaner Filter A Genuine Hyundai air cleaner filter is
recommended when the filter is re- placed. F060J01A-AAT
o Spark Plugs (For Gasoline Engine)
Make sure to install new spark plugs of the correct heat range. F070C01A-AAT o Coolant The coolant should be changed at the intervals specified in the mainte- nance schedule.
F060E01MC-AAT
o Timing Belt (Gasoline)
Inspect all parts related to the timing
belt for damage and deformation.Replace any damaged parts immedi- ately.
F060G01A-AAT
o Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap
should be inspected at those intervalsspecified in the maintenance sched-ule. Make sure that a new vapor hose or fuel filler cap is correctly replaced. F060F01A-AAT
o Vacuum, Crankcase Ventila-
tion Hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical dam-age. Hard and brittle rubber, cracking, tears, cuts, abrasions, and excessiveswelling indicate deterioration. Partic- ular attention should be paid to exam- ine those hose surfaces nearest tohigh heat sources, such as the ex- haust manifold.
Inspect the hose routing to assure
that the hoses do not come in contactwith any heat source, sharp edges or moving component which might causeheat damage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make surethey are secure, and that no leaks are present. Hoses should be replaced immediately if there is any evidenceof deterioration or damage. F070B01A-GAT o Cooling System Check the cooling system part, such as radiator, coolant reservoir, hoses and connections for leakage and dam- age. Replace any damaged parts.

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

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.
