IF THE ENGINE WILL NOT START Seek assistance from the nearest Hyundai dealer with regard to the method of ignition andfuel system diagnosis.
CAUTION:If the engine refuses to start, no attempt
should be made to push or tow start thevehicle. Vehicles with automatic transaxleor fuel injection will not be able to bestarted in this manner since no drive istransmitted through the automatic transaxlewhilst the engine is not running, and in thecase of fuel injected derivatives, the fuelpump will not operate under tow start con-ditions. In addition, if the vehicle isequipped with an exhaust catalyst, dam-age to the catalyst may result if the vehicleis tow started. SD020B1-E

1. Check fuel Level
2. Check all connectors at ignition coil and spark plugs.Replace any that may 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 qualified assistance.
1. If the vehicle is fitted with manual transaxle,
ensure that the clutch pedal is depressed whilst cranking the engine. If the vehicle isfitted with automatic transaxle, ensurethat the transaxle selector is at the "P"or"N" position.
2. Check the battery terminals and connec- tions to ensure that these are clean andalso tight.
3. If the ignition warning lights dim when the engine is cranked and the battery termi-nals have been checked, a dischargedbattery is indicated.
4. Do not attempt to push or tow start the vehicle, refer to "Jump Starting" for infor-mation regarding engine starting when thebattery is discharged. AD020D1-A

IN CASE OF EMERGENCY
WARNING: While the engine is running, keep hands
and clothing away from moving parts such as the fan and drive belts to preventinjury.
WARNING (Diesel only): Never work on injection system with en-
gine running or within 30 seconds after shutting off engine. High pressure pump,rail, injectors and high pressure pipes aresubject to high pressure even after theengine stopped. The fuel jet produced byfuel leaks may cause serious injury, if ittouch the body. People using pacemak-ers should not move than 30cm closer tothe ECU or wiring harness within theengine room while engine is running,since the high currents in the CommonRail system produce considerable mag-netic fields.
5. If the water pump drive belt is broken or coolant is leaking out, stop the engine immediately and call the nearest Hyundaidealer for assistance.
WARNING: Do not remove the radiator cap when the
engine is hot since steam and boiling wa- ter may be ejected from the radiator result-ing in burns or scalding. D040A01FC-EAT TEMPORARY SPARE TYREThe following instructions for the temporary spare tyre should be observed:
1. Check inflation pressure as soon as pos-
sible after installing the spare tyre, and adjust to the specified pressure. The tyrepressure should be periodically checkedand maintained at the specified pressurewhile the tyre is stored. 2. The spare tyre should only be used tem-
porarily and should be returned to theluggage compartment as soon as the origi-nal tyre can be repaired or replaced.
3. Continuous use at speeds of over 80 km/h (50 mph) is not recommended.
4. As the temporary spare tyre is specifically designed for your car, it should not beused on any other vehicle.
5. The temporary spare tyre should not be used on any other wheels, nor shouldstandard tyre, snow tyre, wheel covers ortrim rings be used with the temporaryspare wheel. If such use is attempted,damage to these items or other car com-ponents may occur.
6. The temporary spare tyre pressure should be checked once a month while the tyre isstored.
CAUTION:
o Do not use snow chains with your tem- porary spare tyre.
o Do not use more than one temporary spare tyre at a time.
Spare Tyre Pressure
Type Size Inflation Pressure T115/70R(D)15420 kPa (60 psi)6. If the cause of the overheating cannot be
found, wait until the engine temperature has returned to normal. Then, if coolanthas been lost, carefully remove the radia-tor cap and add water to bring the fluid levelin the reservoir up to the base of theradiator fill opening. Fill the coolant expan-sion tank to the halfway mark.
7. Proceed with caution until it is established that the engine is operating normally. If theengine overheats repeatedly, the advice ofa Hyundai dealer should be sought.
CAUTION: Serious loss of coolant indicates there is a leak in the cooling system and thisshould be checked as soon as possibleby a Hyundai dealer.

MAINTENANCE AND SERVICING REQUIREMENTS To ensure the continued reliability and safety
of the vehicle, certain routine maintenance operations are required at specific mileage ortime intervals.
It is the responsibility of the vehicle owner to
ensure that the maintenance schedules shownin both this Owners Manual and the Warrantyand Service Passport are adhered to.
The new vehicle warranty may be invalidated
if the routine maintenance operations are notperformed in line with the recommendationsoutlined and the safety and durability of thevehicle adversely affected.
It is recommended that all maintenance op-
erations with the exception of the daily oper-ating checks are entrusted to a Hyundaidealer to ensure that the latest repair and maintenance procedures and specializedservicing tools are employed. In addition, theuse of genuine Hyundai replacement parts willensure that the vehicle safety and perfor-mance will not be compromised. NOTE:
The inspection and testing of certain elec-
tronic fuel injection/engine management and automatic transmission control sys-tems require specialised electronic equip-ment specifically designed for Hyundaivehicles. The use of general purpose elec-trical test equipment may result in dam-age to the control unit microprocessors.

MAINTENANCE REQUIREMENTS
SF020C1-E
Specified Scheduled Procedures The Specified scheduled procedures are listed
in the maintenance charts beginning at page 5-2. The operations specified must be per-formed at the time or mileage intervals shownirrespective of whether the mileage intervalhas been reached before the specified timeinterval.
Certain lubricants and components degrade
with both time and mileage (e.g. engine oil andbrake fluid) and therefore it is not permissableto base the maintenance schedule upon mile-age alone. It is strongly recommended thatthe maintenance operations are performed bythe factory-trained or distributor-trained tech-nicians at your Hyundai dealer because of the need for specialized knowledge and toolingand to ensure that no possibility of invalidatingthe manufacturers warranty exists.
The maintenance schedules relate to ve-
hicles operated under normal conditions, ve-hicles which are operated under adverseconditions will require more frequent mainte-nance which is described at page 5-5.
SF030B1-E
SERVICE HISTORY It is important that all scheduled maintenance
services are recorded in the warranty andservice passport to ensure that proof of main-tenance is available when warranty service isrequired.
