To Check the Coolant Level
G050C01FC
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool- ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cold.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect for G050D02A-AAT
To Change the Coolant The coolant should be changed at those inter-
vals specified in the vehicle maintenance sched-ule in Section 5.
CAUTION: Engine coolant can damage the finish of
your car. If you spill engine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park- ing brake and remove the radiator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer’s directions on the enginecoolant container, add the appropriate quan-tity of coolant to the radiator.

sion. Never allow the concentration of anti- freeze to exceed the 60% level or go below the35% level, or damage to the cooling systemmay result. For proper concentration when add-ing or replacing the engine coolant, refer to thefollowing table.
coolant leaks and recheck the fluid level fre-quently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason.

4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This relieves any pressure remaining in the cool-ing system. And remove the radiator cap bypushing down and turning counterclockwise. Now fill the radiator with clean demineralized or distilled water. Continue to add clean deminer-alized or distilled water in small quantities untilthe fluid level stays up in the radiator neck. G060B02S-GAT
REPLACING THE SPARK PLUGS The spark plugs should be changed at theintervals specified in the vehicle maintenancesschedule in Section 5 or whenever engine per-formance indicates they should be changed.Symptoms that suggest poor spark plug perfor-mance include engine misfiring under load, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother spark plugs can result in loss of perfor-mance, radio interference or engine damage. NOTE: When replacing the spark plugs, genuine Hyundai replacement parts are recom-mended. Recommended Spark Plugs:
SSA6060A
Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)
G050D01FC
5. Start the engine, top off the radiator with
water and then add engine coolant to the reservoir until the level is between "LOW"and "FULL".
6. Replace the radiator and reservoir caps and check to be sure the drain cocks are fullyclosed and not leaking.
WARNING: The cooling fan is controlled by engine cool- ant temperature and may sometimes oper-ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition.

FILLING THE WASHER RESERVOIR
The washer fluid reservoir supplies fluid to the windshield washer system. A good quality washer fluid should be used to fill the washer reservoir. The fluid level should bechecked more frequently during bad weather orwhenever the washer system is in more fre-quent use. The capacity of the washer reservoir is 3.0 liters (3.2 U.S. quarts). CAUTION:
o Radiator antifreeze (engine coolant) should not be used in the washer system because it will damage the car's finish.

WINDSHIELD WIPER BLADESHEF-119
The wiper blades should be carefully inspected from time to time and cleaned to remove accu-mulations of road film or other debris. To cleanthe wiper blades and arms, use a clean spongeor cloth with a mild soap or detergent and water.If the wipers continue to streak or smear the
glass, replace them with Genuine Hyundai Re-
placement Parts or their equivalent. NOTE:
o Do not operate the wipers on dry glass. This can result in more rapid wear of the wiper blades and may scratch the glass.
CAUTION: Operating your vehicle without a proper air filter in place can result in excessive enginewear.

CHANGING THE AIR CLEANER FILTER

To change the filter, unsnap the clips around
the cover. When this is done, the cover can be lifted off, the old filter removed and the new filterput in its place. Genuine Hyundai ReplacementParts are recommended.

6-16 G140B01A-AAT Checking the Air Conditioning Operation
1. Start the engine and let it run at a fast idle for
several minutes with the air conditioning set at the maximum cold setting.
2. If the air coming out of the in-dash vents is not cold, have the air conditioning systeminspected by your Hyundai dealer.
CAUTION: Running the air conditioning system for extended periods of time with a low refriger-ant level may damage the compressor. G140C01A-AAT LubricationTo lubricate the compressor and the seals in the system, the air conditioning should be runfor at least 10 minutes each week. This isparticularly important during cool weather whenthe air conditioning system is not otherwise inuse.
G130B02A-AAT
To Replace the Fluid
Recommended brake fluid conforming to DOT
3 or DOT 4 specification should be used. Thereservoir cap must be fully tightened to avoidcontamination from foreign matter or moisture.
NOTE:Do not allow any other liquids to contami-
nate the brake fluid. Seal damage will result.
WARNING: Use caution when handling brake fluid. It
can damage your vision if you get it in your eyes. It will also damage your vehicle’s paintif spilled on it and not removed immediately.
G140A01A-AAT
AIR CONDITIONING CARE Keeping the Condenser Clean
The air conditioning condenser (and engine
radiator) should be checked periodically for accumulation of dirt, dead insects, leaves, etc.These can interfere with maximum cooling effi-ciency. When removing such accumulations,brush or hose them away carefully to avoidbending the cooling fans.
The clutch fluid level in the master cylinder
should be checked when performing other un- der hood services. The system should bechecked for leakage at the same time. Check tomake certain that the clutch fluid level is always

ENGINE COOLANT TEMPERATURE GAUGE
The engine coolant temperature gauge indi-
cates the engine coolant temperature and will, under normal circumstances, give an indica-tion in the "Normal" or centre portion of thescale. Should the indication move into theupper or "Hot" portion of the scale, engineoverheating is indicated. Under these circum-stances, the vehicle should be brought to restas soon as is safe to do so and the engineturned off. Once the engine has cooled some-what, the coolant level and the condition ofthe generator/water pump drive belt should bechecked. If the cause of the overheating can-not be readily established, the assistance of aHyundai dealer should be sought.

WARNING: The engine cooling system is pressurized
and removal of the radiator cap when the engine is hot may cause hot water andsteam to be ejected from the radiator re-sulting in burns and scalding. The radiatorcap must only be removed when the en-gine has cooled. Do not add cold water toa hot engine to avoid the possibility ofengine damage. The use of plain water inthe cooling system is not recommendedsince the aluminium components of thecooling system require the use of a corro-sion inhibitor found in the recommendedEthylene Glycol type anti freeze solutions.
