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 cool-
ant is not allowed to spill onto the paintwork since the finish may becomedamaged. If coolant spillage occurs, theaffected area should be rinsed thoroughlywith water.
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 since burning or scaldingmay result.
2. Prepare a suitable receptacle to collect the displaced coolant and position this underthe radiator drain tap.
3. With the heater temperature control set to the "HOT" position, remove the radiatorcap and open the radiator drain tap. 4. When the engine coolant has drained com-
pletely, close the drain tap ensuring thatthis is not over tightened.
5. Prepare a suitable quantity of new engine coolant (refer to section 9) and pour thisinto the radiator.

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 "L" mark, add coolant of thecorrect concentration until the level is be-tween the "L" and "F" marks. If the level fallsbelow the "L" mark on a regular basis despitebeing topped up, consult a Hyundai authorisedrepairer.

6. Start the engine with the radiator cap still
removed and continue to add coolant as the level decreases as air is expelled fromthe system. When the level remains con-stant, replace the radiator cap and replen-ish the coolant 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 thatyou are not injured by a rotating fanblade. As the engine coolant temperaturedecreases, the fan will automatically shutoff. This is a normal condition.

The wiper blades should be carefully in-
spected from time to time and cleaned to remove accumulations of road film or otherdebris. When the fluid is to be replenished, only aproprietary screen wash additive should beused and in the concentration recommendedby the manufacturer. The windscreen washerreservoir has a total capacity of 3 litres. CAUTION: Engine coolant anti freeze must not be used in the windscreen washer systemsince damage to the paintwork may result. Undiluted windscreen washer additive must not be allowed to come into contact with thepaintwork. If spillage occurs, flush the af-fected area immediately with water. Do notoperate the windscreen washer for morethan 15 seconds continuously or whenthe reservoir is empty since damage tothe washer pump will result.
To clean the wiper blades and arms, use a
clean sponge or cloth with a mild soap ordetergent and water. If the wipers continue tostreak or smear the glass, replace them withgenuine Hyundai replacement.
CAUTION:
o Do not operate the wipers on dry glass since rapid wear and damage to thewindscreen glass may result.
o Keep the blade rubber out of contact with petroleum products such as en-gine oil, petrol, etc.

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. NOTE:
Automatic transaxle fluid is a red color. As driving distance increases, the fluid colorturns darkish red gradually. It is a normalcondition and you should not judge theneed to replace based upon the changingcolor.You must replace the automatic transaxlefluid in accordance with intervals specifiedin the vehicle maintenance schedule insection 5.
CAUTION:The transaxle on fluid level must bechecked with the engine running and atnormal operating temperature and there-fore care must be exercised to preventinjury occurring through contact withrotating or hot parts of the engine.
Ensure that the vehicle is parked on level
ground with the parking brake firmly appliedand the engine cool. Remove the level plugfrom the transaxle when lubricant should be-gin to drip from the level hole. If the level islow and no lubricant is seen to drip, add therequired quantity of lubricant and replace theplug.

Your Hyundai automatic transaxle is specially
designed to operate with HYUNDAI GENU- INE ATF SP III, DIAMOND ATF SP-III, SKATF SP III or other brands approved byHundai Motor Co,. Damage caused by anonspecified fluid is not covered by your newvehicle limited warranty.
CAUTION: Use of aftermarket ATF additives may
cause damage to the automatic transaxle. Only use HYUNDAI GENUINE ATF SP III,DIAMOND ATF SP III, SK ATF SP III orother brands approved by Hyundai MotorCo., If you are having your vehicle ser-viced at a facility other than a Hyundaiauthorised repairer, verify ATF is used foryour vehicle. SG110D2-E
Transaxle fluid level checking
The vehicle must be parked on level groundwith the parking brake firmly applied and theengine 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. Open the bonnet and remove the transaxle dipstick, remembering that care must be ex-ercised to prevent injury occurring throughcontact with hot or rotating parts of the engine.
C090A01FC-D Wipe the dipstick, replace it fully and promptly
remove it again. The fluid level should be between 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 correct operation 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 thedipstick is thoroughly clean prior to levelchecking or adding fluid.
