IN CASE OF EMERGENCY 3-3
WARNING: Whilst the engine is running, keep hands
and clothing away from moving parts such as the fan and drive belts to prevent injury.
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 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.
5. If the water pump drive belt is broken or coolant is leaking out, stop the engine imme- diately and call the nearest Hyundai dealerfor assistance.
WARNING: Do not remove the radiator cap when the
engine is hot since steam and boiling water may be ejected from the radiator resulting inburns or scalding. YD050A1-E
SPARE TYRE For Full Size
The following instructions for the FULL SIZE
spare tyre should be observed:
Check inflation pressure as soon as possible
after installing the spare tyre, and adjust to the specified pressure. The tyre pressure shouldbe periodically checked and maintained at thespecified pressure whilst the tyre is stored.

6. If the cause of the overheating cannot be
found, wait until the engine temperature has returned to normal. Then, if coolant hasbeen lost, carefully remove the radiator capand add water to bring the fluid level in thereservoir up to the base of the radiator fillopening. Fill the coolant expansion tank tothe halfway mark.
7. Proceed with caution until it is established that the engine is operating normally. If theengine overheats repeatedly, the advice of aHyundai dealer should be sought.
CAUTION: Serious loss of coolant indicates there is a
leak in the cooling system and this should be checked as soon as possible by a Hyundaidealer.

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 Owner's 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 Hyundai dealerto ensure that the latest repair and mainte-nance procedures and specialized servicingtools are employed. In addition, the use ofgenuine Hyundai replacement parts will en-sure that the vehicle safety and performancewill not be compromised. DF020C1-E
Specified Scheduled Procedures The specified scheduled procedures are listed
in the maintenance charts beginning at page5-2. The operations specified must be per-formed at the time or mileage intervals shownirrespective of whether the mileage interval has been reached before the specified time interval.
Certain lubricants and components degrade
with both time and mileage (eg, 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 bya Hyundai dealer because of the need forspecialized knowledge and tooling and to en-sure that no possibility of invalidating themanufacturers warranty exists.
The maintenance schedules relate to vehicles
operated under normal conditions, vehicleswhich are operated under adverse conditionswill require more frequent maintenance whichis described at page 5-5. DF020F1-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.

ENGINE OIL
The correct engine oil level is of paramount
importance. An excessively high or low oil level may result in irreparable damage being sus-tained by the engine. The engine oil level mustbe checked on a daily basis, whenever thevehicle is refuelled or before starting a long trip,whichever occurs sooner.
In addition, it is imperative that only an ap-
proved grade and specification of oil is used toavoid the possibility of serious engine damageand premature wear. The use of "budget price"oil is a false economy that must be avoided ifthe maximum reliability and useful life is to beobtained from the vehicle.
SG020B1-E
DAILY OPERATING CHECKS The following items should be checked on a
daily basis or whenever the vehicle is refuelled,whichever occurs sooner.
o Engine oil level.
o Coolant level.
o Power steering fluid level.
o Brake fluid level.
o Windscreen washer fluid level.
o Battery condition.
o Tyre condition and pressures.
o Operation and cleanliness of all lighting equipment.
o Windscreen wiper and washer operation.
o Horn operation.
o Warning light operation.
o Adjustment and cleanliness of mirrors.
o Seat and seat belt adjustment and opera- tion.
o Fluid leakage.
The vehicle must not be driven if the daily
operating checks indicate that any item of equip-ment related to the safety or roadworthiness ofthe vehicle is not functioning correctly. G030B01HP-EAT
Recommended Oil
1. Petrol Engine
A multi grade oil having a specification which
meets A.P.I. specification of SG, SG/CD, SH or SH/CD is recommended. The oil viscosity shouldbe selected according to the operating environ-ment of the engine by means of the table shownabove. The engine oil recommendations arecomplete in themselves and the use of addi-tives is neither required nor recommended. Theuse of engine oil additives may result in invali-dation of the vehicle warranty.
NOTE:The use of a 5W-20 multi grade oil is not
recommended for sustained high speed use.

The engine oil level should be checked with the engine at normal operating temperature and thevehicle parked upon level ground. Prior to checking the level, the vehicle should be allowed to stand for several minutes after theengine has been switched off to allow the oil todrain back to the sump. Withdraw the dipstick and wipe it with a cleanrag. Replace the dipstick fully and withdrawagain when the oil level may be read from thestick. Normal oil level is indicated when the oilis present between the two marks on the stick.It is not necessary to add oil if the level is abovethe lower mark and in any case, oil must not beadded to the degree that the level exceeds theupper mark. Replace the dipstick fully afterchecking the level.

If the indicated oil level is at or below the lower
mark of the dipstick, oil should be added until the level is at or below the upper mark.
To add oil to the engine, remove the filler cap by
rotating in an counterclockwise direction andpour engine oil into the engine. Before checkingthe level again, allow several minutes for the oilto drain into the sump. Replace the oil filler caprotating it in a clockwise direction until tight.
The quantity of oil required to raise the level
from the minimum to maximum level is approx-imately 1 litre (Petrol Engine)/1.4 litres (DieselEngine). G350A01A-EAT
ENGINE OIL CONSUMPTION
Function of engine oil Engine oil has the primary function of lubricat-
ing and cooling the inside of the engine.
Engine oil consumption It is normal that an engine should consume
some engine oil whilst normal driving.
The causes of oil consumption in a normal
engine are as follows;
o Engine oil is used to lubricate pistons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in thecylinder.High negative pressure generated duringengine operation sucks some of this oil intothe combustion chamber. This oil with some oil of the cylinder wall is burned by the high temperature combustiongases during the combustion process.
o The engine oil consumption is strongly ef- fected by the viscosity and quality of oil,engine rpm and driving condition etc. More engine oil may be consumed under severe driving conditions such as highspeeds, frequent acceleration and decelera-tion, compared to normal driving.
