With the "Fresh" mode selected, air enters the vehicle from the outside andis heated or cooled according to the function selected. With the "Recirculation" mode selected, air from within the passenger compart- ment will be drawn through the heatingsystem and heated or cooled according to the function selected. NOTE: It should be noted that prolonged operation of the heating system in "recirculation" mode will give rise to fogging of the windshield and sidewindows and the air within the pas- senger compartment will become stale. In addition, prolonged use ofthe air conditioning with the "Recir- culation" mode selected may result in the air within the passenger com-partment becoming excessively dry.

chains on the tire will provide a greater driving force, but will not prevent sideskids. NOTE: Tire chains are not legal in all prov- inces. Check province laws beforefitting tire chains. C160C01A-AAT Use High Quality Ethylene Glycol Coolant Your Hyundai is delivered with high quality ethylene glycol coolant in the cooling system. It is the only type ofcoolant that should be used because it helps prevent corrosion in the cooling system, lubricates the water pump andprevents freezing. Be sure to replace or replenish your coolant in accor- dance with the maintenance schedule CAUTION:
Don't use the tire chains in 185/55R15 tire to prevent body damage.
! C160G01A-GAT To Keep Locks from Freezing To keep the locks from freezing, squirt an approved de-icer fluid or glycerine into the key opening. If a lock is cov- ered with ice, squirt it with an approvedde-icing fluid to remove the ice. If the lock is frozen internally, you may be able to thaw it out by using a heatedkey. Handle the heated key with care to avoid injury. NOTE: The proper temperature for using the immobilizer key is from -40°C (-40°F) to 80°C(176°F). If you heat the immobilizer key over 80°C(176°F) to open the frozen lock, it may cause damage to the transpon- der in its head.
C160F01A-AAT Check Spark Plugs and Ignition System Inspect your spark plugs as described in Section 6 and replace them if neces-sary. Also check all ignition wiring and components to be sure they are not cracked, worn or damaged in any way.
C160D01A-AAT Check Battery and Cables Winter puts additional burdens on the battery system. Visually inspect the battery and cables as described inSection 6. The level of charge in your battery can be checked by your Hyun- dai 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 cold weather. SeeSection 9 for recommendations. If you aren't sure what weight oil you should use, consult your Hyundai dealer.
in Section 5. Before winter, have yourcoolant tested to assure that its freez-ing point is sufficient for the tempera- tures anticipated during the winter.

IF THE ENGINE OVERHEATS
D030A02TB-AAT If your temperature gauge indicates overheating, you experience a loss of power, or hear loud pinging or knock- ing, the engine is probably too hot. Ifthis happens to you, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the gear selector lever in "P"
(automatic), or neutral (manual transaxle) and set the parking brake. If the air conditioning is on, turn it off.
3. If engine coolant is running out un- der the car or steam is coming outfrom the hood, stop the engine. Donot open the hood until the engine coolant has stopped running or the steaming has stopped. If there is novisible loss of engine coolant and no steam, leave the engine running and check to be sure the enginecooling fan is operating. If the fan is not running, turn the engine off.
5. Start the engine in the car with the
discharged battery using the nor- mal starting procedure. After the engine starts, leave the jumper cables connected and let the enginerun at fast idle or about 2,000 rpm for several minutes.
6. Carefully remove the jumper cables in the reverse order of attachment.
If you do not know why your battery became discharged (because the lights were left on, etc.), have the charging system checked by your Hyundaidealer. 4. Check to see if the water pump drive
belt is missing. If it is not missing,check to see that it is tight. If the drive belt seems to be satisfactory, check for coolant leaking from theradiator, hoses or under the car. (If the air conditioning had been in use, it is normal for cold water to bedraining from it when you stop).
WARNING:
While the engine is running, keephair, hands, and clothing away from moving parts such as the fan and drive belts to prevent injury.

SPARE TIRE
WARNING (Diesel only):
Never work on injection system with engine running or within 30 sec- onds after shutting off engine. High pressure pump, rail, injectors andhigh pressure pipes are subject to high pressure even after the engine stopped. The fuel jet produced byfuel leaks may cause serious in- jury, if it touch the body. People using pacemakers should not movethan 30cm closer to the ECU or wiring harness within the engine room while engine is running, sincethe high currents in the Common Rail system produce considerable magnetic fields. WARNING:
Do not remove the radiator cap whenthe engine is hot. This can allowcoolant to be blown out of the open- ing and cause serious burns.
6. If you cannot find the cause of the overheating, wait until the engine temperature has returned to nor-mal. Then, if the engine coolant has been lost, carefully add coolant to the reservoir (Page 6-14) to bringthe fluid level in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert
for further signs of overheating. Ifoverheating happens again, call a Hyundai dealer for assistance.
!
5. If the water pump drive belt is bro-
ken or coolant is leaking out, stop the engine immediately and call the nearest Hyundai dealer for assis- tance. D040A03A-GAT The following instructions for the FULL SIZE spare tire should be observed: Check inflation pressure as soon as practical after installing the spare tire, and adjust to the specified pressure. The tire pressure should be periodi-cally checked and maintained at the specified pressure while the tire is stored.

CHANGING THE OIL AND FILTER
G350A01A-GAT ENGINE OIL CONSUMPTION Function of Engine Oil Engine oil has the primary function of lubricating and cooling the inside of theengine. Engine oil consumption It is normal that an engine should consume some engine oil while nor-mal driving. The cause of oil consump- tion in a normal engine are as follows;
o Engine oil is used to lubricate pis-
tons, piston rings and cylinders. A thin film of oil is left on the cylinderwall when a piston moves down- wards in the cylinder. High negative pressure generated during engineoperation sucks some of the oil into the combustion chamber. This oil with some oil of the cylinderwall is burned by the high tempera-
ture combustion gases during the combustion process.
o The engine oil consumption is strongly effected by the viscosityand quality of oil, engine rpm anddriving condition etc. The engine oil is more consumed under severe driving conditions such as highspeeds and frequent acceleration and deceleration than normal driv- ing condition.

Oil filler cap
Drain plug Oil filter
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 counterclockwise.
2. Add oil, then check the level again.
Do not overfill.
3. Replace the cap by turning it clock- wise.
The distance between the "F" and "L" marks is equal to about 1 liter(Gasoline Engine)/1.2 liter(Diesel Engine) of oil.
WARNING:
Be very careful not to touch the radia-tor hose when checking the engine oil as it may be hot enough to burn you.

CHECKING AND CHANGING THE ENGINE COOLANT
G050A01A-AAT G050B01A-AAT Recommended Engine Coolant Use a high quality ethylene-glycol cool- ant in a 50/50 mix with water. Theengine coolant should be compatible with aluminum engine parts. Additional corrosion inhibitors or additives shouldnot be used. The cooling system must be maintained with the correct con- centration and type of engine coolantto prevent freezing and corrosion. Never allow the concentration of anti- freeze to exceed the 60% level or gobelow the 35% level, or damage to the cooling system may result. For proper concentration when adding or replacingthe engine coolant, refer to the following table.
WARNING:
Do not remove the radiator cap when the engine is hot. When the engine ishot, the engine coolant is under pres- sure and may erupt through the open- ing if the cap is removed. You couldbe seriously burned if you do not observe this precaution. Do not re- move the radiator cap until the radia-tor is cool to the touch.

G050C01A-GAT To Check the Coolant Level The coolant level can be seen on the side of the plastic coolant reservoir. The level of the coolant should be between the "L" and "F" lines on thereservoir when the engine is cold. If the level is below the "L" mark, add engine coolant to bring it up between "L" and"F". If the level is low, inspect for coolant leaks and recheck the fluid level frequently. If the level drops again,visit your Hyundai dealer for an inspec- tion and diagnosis of the reason.

G050D02A-AAT To Change the Coolant The coolant should be changed at those intervals specified in the vehiclemaintenance schedule in Section 5.
CAUTION:
Engine coolant can damage the fin-ish of your car. If you spill engine coolant on the car, wash it off thor- oughly with clean water.
!
1. Park the car on level ground, set the parking brake and remove the ra- diator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on theradiator. Allow all the engine coolantto drain from the cooling system, then securely close the drain cock.
3. Check Section 9 for the capacity of the cooling system in your car. Then,following the manufacturer's direc- tions on the engine coolant contain-er, add the appropriate quantity of coolant to the radiator. 4. Turn the radiator cap counterclock-
wise without pressing down on it, until it stops. This relieves any pres- sure remaining in the cooling sys- tem. And remove the radiator capby pushing down and turning coun- terclockwise. Now fill the radiator with clean dem-ineralized or distilled water. Con- tinue to add clean demineralized or distilled water in small quantitiesuntil the fluid level stays up in the radiator neck. G050D02A
5. Start the engine, top off the radiator with water and then add engine coolant to the reservoir until thelevel is between "L" and "F".
6. Replace the radiator and reservoir
caps and check to be sure the draincocks are fully closed and not leak- ing.

REPLACING THE SPARK PLUGS
WARNING:
The cooling fan is controlled by engine coolant temperature andmay sometimes operate even when the engine is not running. Use ex- treme caution when working nearthe blades of the cooling fan so that you are not injured by a rotating fan blade. As the engine coolant tem-perature decreases, the fan will auto- matically shut off. This is a normal condition.

The spark plugs should be changed at the intervals specified in the vehicle maintenances schedule in Section 5 or whenever engine performance indicatesthey should be changed. Symptoms that suggest poor spark plug perfor- mance include engine misfiring underload, loss of fuel economy, poor accel- eration, etc. When spark plugs are re- placed, always use spark plugs recom-mended by Hyundai. The use of other spark plugs can result in loss of perfor- mance, radio interference or enginedamage. NOTE: When replacing the spark plugs, genuine Hyundai replacement parts are recommended. Recommended Spark Plugs:
Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm(0.028 ~ 0.032 in.)
