If Engine Doesn't Turn Over or Turns Over Slowly
1. If your car has an automatic transaxle, be sure the gear selector lever is in "N" or "P" and the emer-gency brake is set.
2. Check the battery connections to be
sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you operatethe starter, the battery is discharged.
4. Check the starter connections to be sure they are securely tightened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump Starting". D010C01A-AAT If Engine Turns Over Normally but Does Not Start
D010B02E
WARNING:
If the engine will not start, do not push or pull the car to start it. This could result in a collision or causeother damage. In addition, push or pull starting may cause the cata- lytic converter to be overloaded andcreate a fire hazard.
1. Check fuel level.2. With the key in the "OFF" position,check all connectors at ignition coilsand spark plugs(For Gasoline En-gine) or check all connectors at glow plug and glow plug relay(For Diesel Engine). Reconnect any thatmay be disconnected or loose.
3. Check fuel line in the engine room.4. If engine still refuses to start, call a
Hyundai dealer or seek other quali- fied assistance. D010C01E

check for coolant leaking from the radiator, hoses or under the car. (Ifthe air conditioning had been in use, it is normal for cold water to be draining from it when you stop).
WARNING:
While the engine is running, keephair, hands, and clothing away from moving parts such as the fan and drive belts to prevent injury. 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.
WARNING:
Do not remove the radiator cap when the engine is hot. This can allow coolant to be blown out of the open-ing and cause serious burns.
WARNING (Diesel only):
Never work on injection system withengine 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
!
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 6-16) to bringthe fluid level in the reservoir up to the halfway mark. 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.

7. Proceed with caution, keeping alert
for further signs of overheating. If overheating happens again, call a Hyundai dealer for assistance.

air may leak from the tire. If you lose a valve 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.
IF YOUR VEHICLE MUST BE TOWED
D080A01O-GAT If your vehicle has to be towed, it should be done by your Hyundai dealeror a commercial tow truck service. This will help assure that your vehicle is not damaged in towing. Also, profes-sionals are generally aware of local laws governing towing. In any case, rather than risk damage to your car, itis suggested that you show this infor- mation to the tow truck operator. Be sure that a safety chain system is usedand that all local laws are observed. It is recommended that your vehicle be towed with a wheel lift and dollies orflatbed equipment with all the wheels off the ground.

8EXPLANATION OF SCHEDULED 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 and replace if necessary. Drive belts should be checked periodically forproper tension and adjusted as neces- sary. 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. WARNING (Diesel only):
Never work on injection system with engine running or within 30 sec- onds after shutting off engine. Highpressure pump, rail, injectors and high pressure pipes are subject to high pressure even after the enginestopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body. People usingpacemakers should not move than 30cm closer to the ECU or wiring harness within the engine roomwhile engine is running, since the high currents in the Common Rail system produce considerable mag-netic fields.

o Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.Replace any damaged or leaking partsimmediately.

recommended when the filter is re- placed. F060J01A-AAT
o Spark Plugs Make sure to install new spark plugs of the correct heat range. F070B01A-GAT
o Cooling System Check the cooling system part, such as radiator, coolant reservoir, hosesand connections for leakage and dam- age. Replace any damaged parts.
F060E01A-AAT
o Timing Belt
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 inter- vals specified in the maintenanceschedule. Make sure that a new va- por 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, crack- ing, tears, cuts, abrasions, and ex-cessive swelling indicate deteriora- tion. Particular attention should be paid to examine those hose surfacesnearest to high heat sources, such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact withany heat source, sharp edges or mov- ing component which might cause heatdamage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make sure they aresecure, and that no leaks are present. Hoses should be replaced immedi- ately if there is any evidence of dete-rioration or damage. F060N02E-GAT
o Valve Clearance
Inspect excessive valve noise and/or engine vibration and adjust if neces- sary. A qualified technician shouldperform the operation.

To Change the Coolant
The coolant should be changed at
those intervals specified in the ve- hicle maintenance schedule in Sec- tion 5.
! CAUTION:
Engine coolant can damage the
finish of your car. If you spill en- gine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radia- tor cap when cool.
2. Be sure your drain receptacle is in
place. Open the drain cock on theradiator. Allow all the engine cool- ant to drain from the cooling sys- tem, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car.Then, following the manufacturer's directions on the engine coolant container, add the appropriatequantity of coolant to the radiator.
!WARNING:
Remove the radiator cap when the
radiator is cool. 5. Start the engine, top off the radiator
with water and then add engine coolant to the reservoir until thelevel is between "L" and "F".
6. Replace the radiator and reservoir
caps and check to be sure the draincocks are fully closed and not leak- ing.

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.

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.
