filter should be changed by an authorized Hyundai dealer. G050A01A-AAT
CHECKING AND CHANGING THE ENGINE COOLANT
WARNING: Do not remove the radiator cap when the
engine is hot. When the engine is hot, the engine coolant is under pressure and mayerupt through the opening if the cap isremoved. You could be seriously burned ifyou do not observe this precaution. Do notremove the radiator cap until the radiator iscool to the touch. NOTE: Always dispose of used engine oil in an environmentally acceptable manner. It is sug-gested that it be placed in a sealed containerand taken to a service station for maybereclaimation. Do not pour the oil on theground or put it into the household trash. WARNING: Used motor oil may cause irritation or
cancer
of the skin if left in contact with the skin for prolonged periods of time. Wash your handsthoroughly with soap and warm water assoon as possible after handling used oil.

Checking the Battery Keep the battery clean. Any evidence of corro-
sion around the battery posts or terminals should be removed using a solution of household bak-ing soda and warm water. After the batteryterminals are dry, cover them with a light coat-ing of grease.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk ofmagnesia, eat a raw egg or drink vegetableoil. Get medical assistance as soon aspossible.
While batteries are being charged (either by abattery charger or by the vehicle’s alternator),they produce explosive gases. Always observethese warnings to prevent injuries from occur-ring:
o Charge batteries only in a well ventilated area.
o Do not permit flames, sparks or smoking in the area.
o Keep children away from the area.
Gasoline engine
The power steering fluid level should be checked
regularly.
To check the power steering fluid level, be sure
the ignition is "OFF", then check to make cer- tain that the power steering fluid level is be-tween the "MAX" and "MIN" level markings onthe fluid reservoir.

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

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.
