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 Engine 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. G030A01FC-EAT
ENGINE OIL
The correct engine oil level is of paramount
importance. An excessively high or low oil levelmay result in irreparable damage being sus-tained by the engine. The engine oil levelmust be checked on a daily basis, wheneverthe vehicle is refuelled or before starting along 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.

Engine Oil Level NOTE: SAE 0W-30 oil is for extra cold zone and
to be restricted by driving condition and dealing area. (Especially, not recommend-ed for sustained high loaded and highspeed operation.) The engine oil level should be checked with
the engine at normal operating temperatureand the vehicle 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 clean
rag. 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 thestick. It is not necessary to add oil if the levelis above the lower mark and in any case, oilmust not be added to the degree that the levelexceeds the upper mark. Replace the dip-stick fully after checking the level. SG030D2-E
ENGINE OIL REPLENISHMENT
If the indicated oil level is at or below the lower
mark of the dipstick, oil should be added untilthe 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 checking

6-6 the level again, allow several minutes for the oil to drain into the sump. Replace the oil fillercap rotating it in a clockwise direction untiltight. The quantity of oil required to raise the level from the minimum to maximum level is approx-imately 1 litre. The distance between the "F" and "L" marks is equal to about 1 liter(Gasoline Engine)/1.2liter(Diesel Engine) of oil.
o The engine oil consumption is strongly
effected by the viscosity and quality of oil,engine rpm and driving condition etc. The engine oil is more consumed under severe driving conditions such as highspeeds and frequent acceleration and de-celeration than normal driving condition.
ZG030E1-A
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 while normal driving. The cause of oil consumption in a normal engine are asfollows;
o Engine oil is used to lubricate pistons, piston rings and cylinders. A thin film of oil is left on the cylinder wallwhen a piston moves downwards in thecylinder. High negative pressure generatedduring engine operation sucks some of theoil into the combustion chamber. This oil with some oil of the cylinder wall is burned by the high temperature combustiongases during the combustion process. SG040A1-E

Oil filler cap
Drain plug
Oil filter The engine oil and filter must be changed at
the time or mileage interval specified in the maintenance schedule. If the vehicle is oper-ated under severe or adverse conditions, theoil and filter must be replaced more frequently.
To replace the oil and filter, proceed as fol-
lows:
1. Ensure that the engine is at normal operat- ing temperature and park the vehicle on level ground with the parking brake se-curely applied and the engine turned off.
2. Open the bonnet and remove the oil filler cap.
3. Prepare a suitable receptacle to collect the displaced oil and remove the drain plugfrom the sump.
CAUTION: The oil being drained from the engine will
be hot. Care should be exercised to pre- vent scalding.

ENGINE COOLANT CHECKING AND REPLACING WARNING: Do not remove the radiator cap when the
engine is hot, since the system is pressur- ized and coolant may be ejected from theradiator resulting in scalding.
SG050B1-E
Coolant recommendations
G050B01FC
G050B02FC
Gasoline engine Diesel engine
Only ethylene glycol based coolant with a
corrosion inhibitor suited to aluminium alloy engine components should be used in thecooling system. No further additives or inhibi- tors should be used. The coolant specific gravity should be checked as prescribed inthe maintenance schedule to ensure adequatefrost and corrosion protection. In addition, theengine coolant must be replaced at the speci-fied interval since the corrosion inhibitor prop-erties deteriorate with time.
It is important to note that whilst an increase
in the concentration of anti freeze gives anincrease in the level of frost protection, asolution which is in excess of 65% anti freezewill result in reduced frost protection andengine overheating. Therefore the recom-mended concentration of 50% should not beexceeded for general use.
The use of methanol based anti freeze com-
pounds may result in engine overheating andwill invalidate the vehicle warranty.
4. When the oil has drained from the sump,
replace the drain plug using a new washerensuring that the plug is not over tight-ened.
5. Remove the oil filter by rotating counter- clockwise, using a proprietary oil filter re-moval tool if necessary. Note that the oilfilter will contain approximately 0.5 litres ofoil and this should be collected in a suit-able receptacle.
6. Install a new oil filter having smeared the sealing ring with clean oil and rotatingclockwise until the filter contacts the mount-ing and then a further one half turn. Do notover-tighten Tightening torque: 2.3 ~ 2.5 kgf.m
7. Pour the specified quantity of the recom- mended oil into the engine and replace the filler cap. Start the engine and ensure thatno oil leaks exist. Turn off the engine andafter a couple minutes, recheck the oillevel.
WARNING:Prolonged and repeated contact with used
engine oils may result in serious skin dis-orders including dermatitis and cancer.Avoid contact with skin as far as possibleand always wash thoroughly after any con-tact. Keep used oils out of reach of chil-dren. It is illegal to pollute drains, watercourses and soil. Use only authorized wastecollection facilities including civic amenity sites and garages for the disposal of usedoil and oil filters. If in doubt, contact thelocal authority for disposal instructions.

Engine Coolant Level
SG050D1-E
To Change the Engine Coolant The engine coolant should be changed at
those intervals specified in the vehicle main- tenance schedule in Section 5.
NOTE:Care should be taken to ensure that cool-
ant is not allowed to spill onto thepaintwork since the finish may becomedamaged. If coolant spillage occurs, theaffected area should be rinsed thoroughlywith water. The engine coolant level may be observed
through the side of the plastic coolant reservoir(expansion tank) when the engine is cold. If thelevel is below the "LOW" mark, add coolant ofthe correct concentration until the level is be-tween the "LOW" and "Full" marks. If the levelfalls below the "LOW" mark on a regular basisdespite being topped up, consult a Hyundaidealer. 1. Park the vehicle on level ground and en-
sure that the parking brake is firmly ap-plied, and the engine allowed to cool. DO NOT ATTEMPT THIS OPERATION WHILST THE ENGINE IS HOT SINCEBURNING OR SCALDING MAY RESULT.
2. Prepare a suitable receptacle to collect the displaced coolant and position this under theradiator drain tap.
3. With the heater temperature control set to the "HOT" position, remove the radiator capand open the radiator drain tap.
4. When the engine coolant has drained com- pletely, close the drain tap ensuring that thisis not over tightened.
5. Prepare a suitable quantity of new engine coolant (refer to section 9) and pour thisinto the radiator.
6. Start the engine with the radiator cap still removed and continue to add coolant as thelevel decreases as air is expelled from thesystem. When the level remains constant,replace the radiator cap and replenish thecoolant reservoir.
7. When the engine is hot, check to ensure that no coolant leaks are present.
WARNING: The cooling fan is controlled by engine coolant temperature and may sometimesoperate even when the engine is not run-ning. Use extreme caution when workingnear the blades of the cooling fan so that
