2003 Hyundai Coupe maintenance schedule

DRIVING YOUR HYUNDAI 2- 11
off your engine and restart only when you're ready to go.
o Remember, your Hyundai does not require extended warm-up. As soon as the engine isrunning smoothly, you can drive away. Invery cold weather, however, give your enginea slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too high a gear result-ing in the engine bucking. If this happens, shiftto a lower gear. Over-revving is racing theengine beyond its safe limit. This can beavoided by shifting at the recommendedspeeds.
o Use your air conditioning sparingly. The air conditioning system is operated by enginepower so your fuel economy is reduced whenyou use it.
crease wear on these components. In addi-tion, driving with your foot resting on the brakepedal may cause the brakes to overheat,which reduces their effectiveness and maylead to more serious consequences.
o Take care of your tires. Keep them inflated to the recommended pressure. Incorrect infla-tion, either too much or too little, results inunnecessary tire wear. Check the tire pres-sures at least once a month.
o Be sure that the wheels are aligned correctly. Improper alignment can result from hittingcurbs or driving too fast over irregular surfac-es. Poor alignment causes faster tire wearand may also result in other problems as wellas greater fuel consumption.
o Keep your car in good condition. For better fuel economy and reduced maintenancecosts, maintain your car in accordance withthe maintenance schedule in Section 5. If youdrive your car in severe conditions, morefrequent maintenance is required (see Sec-tion 5 for details).
o Keep your car clean. For maximum service, your Hyundai should be kept clean and free ofcorrosive materials. It is especially importantthat mud, dirt, ice, etc. not be allowed toaccumulate on the underside of the car. Thisextra weight can result in increased fuel con-sumption and also contribute to corrosion.
o Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel economy.
o Don't let the engine idle longer than neces- sary. If you are waiting (and not in traffic), turn C150A01A-AAT
SMOOTH CORNERING
Avoid braking or gear changing in corners, espe-cially when roads are wet. Ideally, corners shouldalways be taken under gentle acceleration. If youfollow these suggestions, tire wear will be held toa minimum. C160A01A-AAT WINTER DRIVING The more severe weather conditions of winter result in greater wear and other problems. Tominimize the problems of winter driving, youshould follow these suggestions:
If the indicator remains lit even after the enginehas been started, have your car checked by anauthorized Hyundai dealer. NOTE:
1) When the TCS-OFF indicator illuminates,
traction control is automatically deacti-vated for safety.
2) This warning function is not provided when the driver selects the TCS-OFF mode.
C140A01A-GAT DRIVING FOR ECONOMY You can save fuel and get more kilometers from your car if you follow these suggestions:
o Drive smoothly. Accelerate at a moderate rate. Don't make "jack-rabbit" starts or full- throttle shifts and maintain a steady cruisingspeed. Don't race between stoplights. Try toadjust your speed to that of the other traffic soyou don't have to change speeds unneces-sarily. Avoid heavy traffic whenever possible.Always maintain a safe distance from othervehicles so you can avoid unnecessary brak-ing. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel your car uses. Driving ata moderate speed, especially on the high-way, is one of the most effective ways toreduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This can increase fuel consumption and also in-

DRIVING YOUR HYUNDAI
2- 12 C160G01A-GAT To Keep Locks from FreezingTo keep the locks from freezing, squirt an ap- proved de-icer fluid or glycerine into the keyopening. If a lock is covered with ice, squirt it withan approved de-icing fluid to remove the ice. Ifthe lock is frozen internally, you may be able tothaw it out by using a heated key. Handle theheated key with care to avoid injury. NOTE: The proper temperature for using the immo-bilizer key is from -40°C to 80°C. If you heatthe immobilizer key over 80°C to open thefrozen lock, it may cause damage to thetransponder in its head. C160H01A-AAT Use Approved Anti-Freeze in Window Washer System To keep the water in the window washer system from freezing, add an approved anti-freeze solu-tion in accordance with instructions on the con-tainer. Window washer anti-freeze is availablefrom Hyundai dealers and most auto parts out-lets. Do not use engine coolant or other types ofanti-freeze as these may damage the finish.
C160B01A-GAT Snowy or Icy ConditionsTo drive your vehicle in deep snow, it may be necessary to use snow tires or to install tirechains on your tires. If snow tires are needed, itis necessary to select tires equivalent in size andtype to the original equipment tires. Failure to doso may adversely affect the safety and handlingof your car. Speeding, rapid acceleration, sud-den brake applications, and sharp turns arepotentially very hazardous practices. Duringdeceleration, use engine braking to the fullestextent. Sudden brake applications on snowy oricy roads may cause skids to occur. You need tokeep sufficient distance between the vehicle infront and your vehicle. Also, apply the brakegently. It should be noted that installing tire chainson the tire will provide a greater driving force, butwill not prevent side skids. NOTE: Tire chains are not legal in all provinces.Check province laws before fitting tire chains. C160C01A-AAT Use High Quality Ethylene Glycol Coolant Your Hyundai is delivered with high quality ethyl- ene glycol coolant in the cooling system. It is theonly type of coolant that should be used becauseit helps prevent corrosion in the cooling system,lubricates the water pump and prevents freezing.Be sure to replace or replenish your coolant in
C160D01F-AAT Check Battery and Cables Winter puts additional burdens on the battery system. Visually inspect the battery and cablesas described in Section 6 (See page 6-18). Thelevel of charge in your battery can be checkedby your Hyundai dealer or a service station. C160E01A-AAT Change to "Winter Weight" Oil if Necessary In some climates it is recommended that a lower viscosity "winter weight" oil be used during coldweather. See Section 9 for recommendations. Ifyou aren't sure what weight oil you should use,consult your Hyundai dealer. C160F01F-GAT Check Spark Plugs and Ignition Sys- tem Inspect your spark plugs as described in Section 6 (See page 6-8) and replace them if necessary.Also check all ignition wiring and components tobe sure they are not cracked, worn or damagedin any way.
accordance with the maintenance schedule inSection 5. Before winter, have your coolant test-ed to assure that its freezing point is sufficient forthe temperatures anticipated during the winter.

CHANGING THE OIL AND FILTER
The engine oil and filter should be changed at those intervals specified in the maintenanceschedule in Section 5. If the car is being drivenin severe conditions, more frequent oil and filterchanges are required. The procedure for changing the oil and filter is as follows:
1. Park the car on level ground and set the parking brake. Start the engine and let itwarm up until the needle on the coolanttemperature gauge moves above the lowestmark. Turn the engine off and place the gearselector lever in "P" (automatic) or reversegear (manual transaxle).
2. Open the hood and remove the engine oil filler cap.
G040A01GK 3. Slide underneath the car and loosen the
drain plug by turning it counterclockwise with a wrench of the proper size. Be surethat a drain pan is in position to catch the oilas it drains out, then remove the drain plug.
WARNING: Be very careful when draining the engine oil as it may be hot enough to burn you!
4. When the oil has stopped draining, replace the drain plug using a new washer and retighten by turning it clockwise. Tightening torque :
4.5 ~ 4.0 kgf.m (1.6/2.0L) 4.5 ~ 3.5 kgf.m (2.7L)
5. Remove the oil filter by turning it counter- clockwise with a oil filter wrench of the proper size. A certain amount of oil willcome out when you remove the filter. So besure to have your drain pan in place under-neath it.
6. Install a new oil filter in accordance with the instructions on the carton or on the filteritself. Do not over-tighten. Tightening torque: 1.2 ~ 1.6 kgf.m.Be sure that the mounting surface on the engine is clean and that the old gasket isremoved completely. Lubricate the new gas-ket on the filter with clean engine oil beforeinstallation.

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.
o A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. 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.
o The engine oil consumption is strongly ef- fected by the viscosity and quality of oil,engine rpm and driving condition etc. Moreengine oil may be consumed under severedriving conditions such as high speeds, fre-quent acceleration and deceleration, com-pared to normal driving condition. V6

check to be sure the drain cocks are fully closed 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 coolant 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. G060A02Y-GAT

Your engine was originally equipped with plati- num-tipped spark plugs. (For 2.7L only). Platinum-tipped spark plugs will last longer than conventional type spark plugs and can be iden-tified by blue lines on the ceramic shell. NOTE: Do not clean or regap platinum-tipped spark plugs.
G060B01GK-GAT
Replacing the Spark Plugs The spark plugs should be changed at the
intervals specified in the vehicle maintenanceschedule 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:

To Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance schedule in Section 5.
NOTE: 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 engine coolant to the radiator.
4. Turn the radiator cap counterclockwise with- out pressing down on it, until it stops. Thisrelieves any pressure remaining in the cool-ing system. And remove the radiator cap bypushing down and turning counterclockwise. Now fill the radiator with clean demineral- ized or distilled water. Continue to add cleandemineralized or distilled water in small quan-tities until the fluid level stays up in theradiator neck. DOHC1.0~1.1 mm (0.039 ~ 0.043 in.)
