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.

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 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 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

Transaxle fluid level checking
The vehicle must be parked on level ground
with the parking brake firmly applied and the engine at normal operating temperature. (Nor-mal operating temperature will only be achievedwhen the vehicle has been driven for 6 miles ormore). With the engine idling and the footbrake ap-
plied, the transaxle selector should be movedfrom the "P" position through to the "L" positionand back to the "N" or "P" position.

AUTOMATIC TRANSAXLE FLUID The automatic transaxle fluid level should be
checked and changed at those intervals pre- scribed in the maintenance schedule. It is ofparamount importance that only the specifiedfluid is used when replenishing or changing thefluid. The use of other fluids may irreparablydamage the transaxle and invalidate the manu-facturers warranty. In addition the ingress of dirtor lint may prevent correct functioning of thetransaxle and care must be exercised to pre-vent the ingress of such matter.
CAUTION: The transaxle on fluid level must be checked
with the engine running and at normal oper- ating temperature and therefore care mustbe exercised to prevent injury occurringthrough contact with rotating or hot parts ofthe engine. G110B03A-AAT
Recommended Fluid Your Hyundai automatic transaxle is specially designed to operate with DIAMOND ATF SP- III
or SK ATF SP- III.
Damage caused by a nonspecified fluid is notcovered by your new vehicle limited warranty.
Wipe the dipstick, replace it fully and promptlyremove it again. The fluid level should bebetween the upper and lower marks. Fluidneed only be added if the level is at or belowthe lower mark and must never be increasedabove the higher mark. If additional fluid isrequired, this should be poured into the trans-mission through the dipstick tube with the aidof a suitable funnel. CAUTION: The automatic transaxle unit is a preci-sion engineered assembly and correctoperation is dependant upon the exclu-sion of dirt and lint from the unit. There-fore, it is imperative that only lint freecloth (eg nylon) is used for wiping thedipstick and that the area around the

Brake Fluid Level
The fluid level in the brake fluid reservoir
should be checked periodically. The levelshould be between the "MIN" and "MAX"marks on the side of the reservoir. If the levelis at or below the "MIN" mark, fluid should beadded having carefully cleaned the area sur-rounding the reservoir cap to ensure that dirtis not allowed to enter the system. It shouldbe borne in mind that the brake fluid level willdecrease slightly as the friction linings of thepads and shoes become worn and that this isa normal condition.

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 thatyou are not injured by a rotating fan blade.As the engine coolant temperature de-creases, the fan will automatically shutoff. This is a normal condition.
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 it touch 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.
