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.

To Check the Oil Level G030D01A-GAT
Adding Oil
Before checking the oil, warm up the engine to
the normal operating temperature and be sure it is parked on level ground. Turn the engine off.
Wait five minutes, then remove the dipstick,
wipe it off, fully reinsert the dipstick and with-draw it again. Then note the highest level the oilhas reached on the dipstick. It should be be-tween the upper ("FULL") and lower ("LOW")range. If the oil level is close to or below the "L" mark,
add oil until it reaches the "F" mark. To add oil:
1. Remove the oil filler cap by turning it counter- clockwise.
2. Add oil, then check the level again. Do not overfill.
3. Replace the cap by turning it clockwise.
The distance between the "F" and "L" marks is
equal to about 1 liter of oil.HGK211

See the lubrication chart on the page 9-3. NOTE:
o The use of a 5W-20 multi grade oil is not recommended for sustained high speed use.
o When replacing or adding the oil, below SAE 10W-30 is recommended. Using a high viscosity oil of SAE 15W-40 and over makes malfunction of CVVTengine when the engine is cool.

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

SG020B1-E DAILY OPERATING CHECKSThe following items should be checked on a daily basis or whenever the vehicle is refuelled, which-ever occurs sooner.
o Engine oil level.
o Engine coolant level.
o Power steering fluid level.
o Brake fluid level.
o Windscreen washer fluid level.
o Battery condition.
o Tyre condition and pressures.
o Operation and cleanliness of all lighting equip-
ment.
o Windscreen wiper and washer operation.
o Horn operation.
o Warning lamp operation.
o Adjustment and cleanliness of mirrors.
o Seat and seat belt adjustment and operation.
o Fluid leakage. The vehicle must not be driven if the daily oper- ating checks indicate that any item of equipmentrelated to the safety or roadworthiness of thevehicle is not functioning correctly. SG030A1-E ENGINE OILThe correct engine oil level is of paramount importance. An excessively high or low oil levelmay result in irreparable damage being sus-tained by the engine. The engine oil level must bechecked on a daily basis or whenever the vehicleis refuelled, whichever occurs sooner.In addition, it is imperative that only an approvedgrade and specification of oil is used to avoid thepossibility of serious engine damage and prema-ture wear. The use of "budget price" oil is a falseeconomy that must be avoided if the maximumreliability and useful life is to be obtained from thevehicle.
SG030B02GK-E Recommended Oil A multi grade oil having a specification which meets A.P.I. specification of SH, SG or above isrecommended. The oil viscosity should be se-lected according to the operating environment ofthe engine by means of the table shown below.The engine oil recommendations are complete inthemselves and the use of additives is neitherrequired nor recommended. The use of engineoil additives may result in invalidation of thevehicle warranty.

SG030D1-E ENGINE OIL REPLENISHMENT If the indicated oil level is at or below the lower mark of the dipstick, oil should be added until thelevel is at or below the upper mark.To add oil to the engine, remove the filler cap byrotating in an counterclockwise direction andpour engine oil into the engine. Before checkingthe level again, allow several minutes for the oilto drain into the sump. Replace the oil filler caprotating it in a clockwise direction until tight.The quantity of oil required to raise the level from theminimum to maximum level is approximately 1 litre.
SG030C1-E Engine Oil Level The engine oil level should be checked with the engine at normal operating temperature and thevehicle parked upon level ground.Prior to checking the level, the vehicle should beallowed 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 withdraw againwhen the oil level may be read from the stick.Normal oil level is indicated when the oil ispresent between the two marks on the stick. It isnot necessary to add oil if the level is above thelower mark and in any case, oil must not beadded to the degree that the level exceeds theupper mark. Replace the dipstick fully after check-ing the level.
