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.

2 DRIVING YOUR HYUNDAI
20WINTER DRIVINGSMOOTH CORNERING
C150A01A-AAT Avoid braking or gear changing in cor- ners, especially when roads are wet. Ideally, corners should always be taken under gentle acceleration. If you followthese suggestions, tire wear will be held to a minimum. C160A01A-AAT The more severe weather conditions of winter result in greater wear and other problems. To minimize the prob- lems of winter driving, you should fol-low these suggestions: C160B01A-GAT Snowy or Icy Conditions To drive your vehicle in deep snow, it may be necessary to use snow tires orto install tire chains on your tires. If snow tires are needed, it is necessary to select tires equivalent in size andtype to the original equipment tires. Failure to do so may adversely affect the safety and handling of your car.Speeding, rapid acceleration, sudden brake applications, and sharp turns are potentially very hazardous prac-tices. During deceleration, use engine braking to the fullest extent. Sudden brake applications on snowy or icyroads may cause skids to occur. You need to keep sufficient distance be- tween the vehicle in front and yourvehicle. Also, apply the brake gently. It should be noted that installing tire 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 of coolant that should be used because ithelps prevent corrosion in the cooling system, lubricates the water pump and prevents freezing. Be sure to replaceor replenish your coolant in accor- dance with the maintenance schedule 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 6-11) to bring thefluid 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 broken
or coolant is leaking out, stop the engine immediately and call the near- est Hyundai dealer for assistance. 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.
CAUTION:
Serious loss of engine coolant indi-cates there is a leak in the coolingsystem and this should be checked as soon as possible by a Hyundai dealer. Spare Tire Pressure

6MAINTENANCE PRECAU- TIONS
!
G020D01TG-GAT Improper or incomplete service may result in problems. This section gives instructions only for the maintenance items that are easy to perform.Several procedures should be done by an authorized Hyundai dealer. NOTE: Improper owner maintenance dur- ing the warranty period may affect warranty coverage. WARNING:
o Performing maintenance work on a vehicle can be dangerous. Youcan be seriously injured while performing some maintenance procedures. If you lack sufficientknowledge and experience or the proper tools and equipment to do the work, have it done by an autho-rized Hyundai dealer.
o Working under the hood with the
engine running is dangerous. It becomes even more dangerous when you wear jewelry or looseclothing. These can become en- tangled in moving parts and result in injury. Therefore, if you mustrun the engine while working un- der the hood, make certain that you remove all jewelry (especiallyrings, bracelets, watches, and necklaces) and all neckties, scarves, and similar loose cloth-ing before getting near the engine or cooling fans.
CHECKING THE ENGINE OIL
G030A02O-GAT Recommended Oil Gasoline Engine
Engine oil is essential to the perfor- mance and service of the engine. It is suggested that you check the oil level at least once a week in normal use andmore often if you are on a trip or driving in severe conditions. The engine oil quality should meet the following classification. API SJ, SL or ABOVE, ILSAC GF-3 or ABOVE G030B01JM

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 cylinder wall when a piston moves down- wards in the cylinder. High negativepressure generated during engine operation sucks some of the oil into the combustion chamber.This oil with some oil of the cylinder wall is burned by the high tempera- ture combustion gases during thecombustion process.
NOTE:
o It is recommended that the engine
oil and filter should be changed by an authorized Hyundai dealer.
o Always dispose of used engine oil in an environmentally acceptablemanner. It is suggested that it beplaced in a sealed container and taken to a service station for maybe reclaimation. Do not pour the oilon the ground or put it into the household trash.
!WARNING:
Used motor oil may cause irritation or cancer of the skin if left in contact with the skin for prolonged periodsof time. Wash your hands thoroughly with soap and warm water as soon as possible after handling used oil.
!
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)/1.5 liter(Diesel Engine) of oil.
WARNING:
Be very careful not to touch the radia-tor hose when adding the engine oilas it may be hot enough to burn you. CAUTION:
Slowly pour the recommended oilby using a funnel. Do not overfill soas not to damage engine.

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.

CHECKING AND CHANGING THE ENGINE COOLANT
G050A01TG-AAT
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. NOTE: It is recommended that the engine coolant should be changed by an authorized Hyundai dealer.
o The engine oil consumption is strongly
effected by the viscosity and qualityof oil, engine rpm and driving condi- tion etc. The engine oil is more con- sumed under severe driving condi-tions such as high speeds and fre- quent acceleration and deceleration than normal driving condition.

G050C01TG-GAT To Check the Coolant Level Gasoline Engine The coolant level can be seen on the side of the plastic coolant reservoir.
OMC055007
OMC055008
Diesel Engine 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.
!WARNING:
The cooling fan is controlled by en- gine coolant temperature and may sometimes operate even when theengine is not running. Use extreme caution when working near the blades of the coolant fan so that youare 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.
! CAUTION:
o Engine coolant can damage the finish of your car. If you spill en- gine coolant on the car, wash it off thoroughly with clean water.
o The engine in your vehicle has
aluminum engine parts and mustbe protected by an ethylene-gly- col base coolant to prevent corro-sion and freezing. And, do not use the hard water. The hard water can cause enginedamage from corrosion, overheat- ing or freezing.
