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.

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.)

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.

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

The fuel gauge indicates the quantity of fuel remaining in the fuel tank. NOTE: The fuel gauge is not intended to giveother than an approximate indication ofthe fuel level and is unsuitable for thepurposes of calculating fuel consumptionfigures. SB215B1-E
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.

IN CASE OF EMERGENCY
WARNING: While the engine is running, keep hands
and clothing away from moving parts such as the fan and drive belts to preventinjury.
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 ittouch 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.
5. If the water pump drive belt is broken or coolant is leaking out, stop the engine immediately and call the nearest Hyundaidealer for assistance.
WARNING: Do not remove the radiator cap when the
engine is hot since steam and boiling wa- ter may be ejected from the radiator result-ing in burns or scalding. D040A01FC-EAT TEMPORARY SPARE TYREThe following instructions for the temporary spare tyre should be observed:
1. Check inflation pressure as soon as pos-
sible after installing the spare tyre, and adjust to the specified pressure. The tyrepressure should be periodically checkedand maintained at the specified pressurewhile the tyre is stored. 2. The spare tyre should only be used tem-
porarily and should be returned to theluggage compartment as soon as the origi-nal tyre can be repaired or replaced.
3. Continuous use at speeds of over 80 km/h (50 mph) is not recommended.
4. As the temporary spare tyre is specifically designed for your car, it should not beused on any other vehicle.
5. The temporary spare tyre should not be used on any other wheels, nor shouldstandard tyre, snow tyre, wheel covers ortrim rings be used with the temporaryspare wheel. If such use is attempted,damage to these items or other car com-ponents may occur.
6. The temporary spare tyre pressure should be checked once a month while the tyre isstored.
CAUTION:
o Do not use snow chains with your tem- porary spare tyre.
o Do not use more than one temporary spare tyre at a time.
Spare Tyre Pressure
Type Size Inflation Pressure T115/70R(D)15420 kPa (60 psi)6. If the cause of the overheating cannot be
found, wait until the engine temperature has returned to normal. Then, if coolanthas been lost, carefully remove the radia-tor cap and add water to bring the fluid levelin the reservoir up to the base of theradiator fill opening. Fill the coolant expan-sion tank to the halfway mark.
7. Proceed with caution until it is established that the engine is operating normally. If theengine overheats repeatedly, the advice ofa Hyundai dealer should be sought.
CAUTION: Serious loss of coolant indicates there is a leak in the cooling system and thisshould be checked as soon as possibleby a Hyundai dealer.
