Recommended Oil Diesel Engine
NOTE: SAE 5W-20 (5W-30), ILSAC GF-3 engine oil is preferred regardless ofregional option and engine varia- tion. If SAE 5W-20, ILSAC GF-3 en- gine oil is not available, secondaryrecommended engine oil for corre- sponding temperature range can be used.

The correct engine oil level is of para- mount importance. An excessively high or low oil level may result in irreparable damage being sustained by the engine. The engineoil level must be checked on a daily basis, whenever the vehicle is refu- elled or before starting a long trip,whichever occurs sooner. In addition, it is imperative that only an
approved grade and specification of oilis used to avoid the possibility of serious engine damage and premature wear. The use of "budget price" oil isa false economy that must be avoided if the maximum reliability and useful life is to be obtained from the vehicle.
The engine oil quality should meet the
following classification:
API class: CH-4 or ABOVE ACEA class: B4 or ABOVE NOTE: SAE 0W-30 oil is for use in very cold
zones. Its use should therefore be restricted only to driving in these type of sub-zero conditions. (Espe-cially, not recommended for sus- tained high engine load and high speed operation.)

The engine oil level should be checked with the engine at normal operating temperature and the vehicle parkedupon level ground. If the indicated oil level is at or below the lower mark of the dipstick, oil should be added until the level is at orbelow the upper mark.
WARNING:
Be very careful not to touch the
radiator hose when checking the engine oil as it may be hot enough to burn you. Prior to checking the level, the vehicle
should be allowed to stand for severalminutes after the engine has been switched off to allow the oil to drain back to the sump.
Withdraw the dipstick and wipe it with
a clean rag. Replace the dipstick fullyand withdraw again when the oil levelmay be read from the stick. Normal oil level is indicated when the oil is present between the two marks on the stick. Itis not necessary to add oil if the level is above the lower mark and in any case, oil must not be added to thedegree that the level exceeds the up- per mark. Replace the dipstick fully after checking the level.

ENGINE OIL CONSUMPTION Function of engine oil
Engine oil has the primary function of lubricating and cooling the inside of the engine.
Engine oil consumption It is normal that an engine should consume some engine oil in the course of normal driving. The cause of oil consumption in a normal engine are asfollows;
o Engine oil is used to lubricate pis- tons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generated duringengine operation sucks some of the oil into the combustion chamber. This oil with some oil of the cylinder wall is burned by the high tempera- ture combustion gases during thecombustion process.
To add oil to the engine, remove the
filler cap by rotating in an counter-clockwise direction and pour engine oil into the engine. Before checking the level again, allow several minutes forthe oil to drain into the sump. Replace the oil filler cap rotating it in a clock- wise direction until tight.
The quantity of oil required to raise the
level from the minimum to maximumlevel is approximately 1 litre.
The distance between the "F" and "L"
marks is equal to about 1 liter(Petrol Engine)/1.2 liter(Diesel Engine) of oil.
!
CAUTION:
Slowly pour the recommended oil into a funnel. Do not overfill toprevent engine to damage.!
WARNING:
Be very careful not to touch the radiator hose when checking the engine oil as it may be hot enoughto burn you. o The engine oil consumption is
strongly effected by the viscosityand quality of oil, engine rpm and driving condition etc. More engine oil may be consumed under severe driving conditions such as high speeds, frequent accelera- tion and deceleration, compared tonormal driving.

The engine oil and filter should be
changed at those intervals specified in the maintenance schedule in Section 5. If the car is being driven in severe conditions, more frequent oil and filter changes are required.
The procedure for changing the oil and
filter is as follows:
1. Park the car on level ground and set the parking brake. Start the engine and let it warm up until the needle on the coolant temperature gauge moves above the lowest mark. Turn the engine off and place the gear selector lever in "P" (automatic) or reverse gear (manual transaxle). 2. Open the bonnet and remove the
engine oil level dipstick.
3. Loosen the oil filter upper cap with a proper tool from the oil filter housing until an O-ring is seen. Then, drainthe oil completely.
CAUTION:
Slowly loosen the oil filter uppercap not to overflow the oil.

WARNING:
Prolonged and repeated contact with used engine oils may result in seri- ous skin disorders including der- matitis and cancer. Avoid contact with skin as far as possible andalways wash thoroughly after any contact. Keep used oils out of reach of children. It is illegal to pollutedrains, water courses and soil. Use only authorized waste collection facilities including civic amenitysites and garages for the disposal of used oil and oil filters. If in doubt, contact the local authority for dis-posal instructions.

ENGINE COOLANT CHECK- ING AND REPLACING
SG050B1-E Coolant recommended G050B01FC
SG050A1-E
WARNING:
Do not remove the radiator cap when the engine is hot, since the system is pressurised and coolant may be ejected from the radiator resultingin scalding.
G050B02FC
Petrol engine Diesel engine
Only ethylene glycol based coolantwith a corrosion inhibitor suited to alu- minium alloy engine components should be used in the cooling system. No further additives or inhibitors should be used. The coolant specific gravityshould be checked as prescribed in the maintenance schedule to ensure adequate frost and corrosion protec-tion. In addition, the engine coolant must be replaced at the specified in- terval since the corrosion inhibitor prop-erties deteriorate with time. It is important to note that whilst an
increase in the concentration of antifreeze gives an increase in the level of frost protection, a solution which is in excess of 65% anti freeze will result inreduced frost protection and engine overheating. Therefore the recom- mended concentration of 50% shouldnot be exceeded for general use. The use of methanol based anti freeze
compounds may result in engine over-heating and will invalidate the vehicle warranty.
NOTE: It is imperative that vehicles fitted
with an air conditioning system have a coolant concentration of the rec-ommended strength at all times. The use of the air conditioning sys- tem when the cooling system isfilled with water only will result in the heater matrix freezing and sub- sequently bursting.

To Change the Coolant
The coolant should be changed at
those intervals specified in the vehicle maintenance schedule in Section 5.
NOTE: Care should be taken to ensure that
coolant is not allowed to spill onto the paintwork since the finish maybecome damaged. If coolant spill- age occurs, the affected area should be rinsed thoroughly with water.
1. Park the vehicle on level ground
and ensure that the parking brake is firmly applied, and the engine al- lowed to cool. Do not attempt this operation whilst the engine is hot since burning or scalding may result. 2. Prepare a suitable receptacle to
collect the displaced coolant and position this under the radiator drain tap.
3. With the heater temperature control set to the "HOT" position, removethe radiator cap and open the radia- tor drain tap.
4. When the engine coolant has drained completely, close the drain tap en-suring that this is not over tight- ened.
5. Prepare a suitable quantity of new engine coolant (refer to section 9)and pour this into the radiator.

BRAKE SYSTEM CHECKING
Fluid level should be within this range
C090A03FC
WARNING:
The cooling fan is controlled by engine 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 tem- perature decreases, the fan will au- tomatically shut off. This is a nor-mal condition. 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 contacts the body.
People using pacemakers should
ensure that they keep a distance of30cm from the ECU or wiring har- ness within the engine room whilst engine is running, since the highcurrents in the Common Rail sys- tem produce considerable magnetic fields. SG120A1-E
CAUTION:
Correct operation of the braking
system is essential to the safe op-eration of the vehicle and therefore, any maintenance operations other than those listed below should beentrusted to a Hyundai authorised repairer.
