9. If the trailer has electric brakes, start your
vehicle and trailer moving, and then apply the trailer brake controller by hand to be sure thebrakes are working. This lets you check yourelectrical connection at the same time.
10. During your trip, check occasionally to be sure that the load is secure, and that thelights and any trailer brakes are still working.
11. Avoid jerky starts, sudden acceleration or sudden stops.
12. Avoid sharp turns and rapid lane changes.
13. Avoid holding the brake pedal down too long or too frequently. This could cause the brakesto overheat, resulting in reduced braking effi-ciency.
14. When going down a hill, shift into a lower gear and use the engine braking effect.When ascending a long grade, downshift thetransmission to a lower gear and reducespeed to reduce chances of engine overload-ing and/or overheating.
15. If you have to stop while going uphill, do not hold the vehicle in place by pressing on theaccelerator. This can cause the automatictransmission to overheat. Use the parkingbrake or footbrake. NOTE:When towing check transaxle fluid more fre-quently. CAUTION: If overheating should occur when towing,(temperature gauge reads near red zone),taking the following action may reduce oreliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. While in stop and go traffic, place the gear
selector in park or neutral and idle theengine at a higher speed.

WHAT TO DO IN AN EMERGENCY

tance. Automobile batteries contain sulfuric acid. This is poisonous and highly corrosive.When jump starting, wear protective glassesand be careful not to get acid on yourself,your clothing or on the car.
o If you should accidentally get acid on your
skin or in your eyes, immediately remove any contaminated clothing and flush the area withclear water for at least 15 minutes. Thenpromptly obtain medical attention. If you mustbe transported to an emergency facility, con-tinue to apply water to the affected area witha sponge or cloth.
o The gas produced by the battery during the jump-start operation is highly explosive. Donot smoke or allow a spark or open flame inthe vicinity.
o The battery being used to provide the jump start must be 12-volt. If you cannot determinethat it is a 12-volt battery, do not attempt touse it for the jump start.
o To jump start a car with a discharged battery, follow this procedure exactly:
1. If the booster battery is installed in another vehicle, be sure the two vehicles are nottouching.
2. Turn off all unnecessary lights and acces- sories in both vehicles. 3. Attach the clamps of the jumper cable in the
exact location shown on the previous page.First, attach one clamp of the jumper cable tothe positive (+) post or cable of the dis-charged battery. Then attach the other end ofthe same cable to the positive (+) post orcable of the booster battery. Next, using theother cable, attach one clamp to the negative(-) post or cable of the booster battery. Thenattach the other end of that cable to a solidmetal part of the engine away from thebattery. Do not connect the cable to anymoving part.
4. Start the engine in the car with the booster battery and let it run for a few minutes. Thiswill help to assure that the booster battery isfully charged. During the jumping operation,run the engine in this vehicle at about 2000rpm.
5. Start the engine in the car with the discharged battery using the normal starting procedure.After the engine starts, leave the jumpercables connected and let the engine run atfast idle or about 2000 rpm for several min-utes.
6. Carefully remove the jumper cables in the reverse order of attachment.
If you do not know why your battery becamedischarged (because the lights were left on,etc.), have the charging system checked by yourHyundai dealer. D030A02A-AAT IF THE ENGINE OVERHEATSIf your temperature gauge indicates overheating, you experience a loss of power, or hear loudpinging or knocking, the engine is probably toohot. If this 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" (auto- matic), 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 under the car or steam is coming out from the hood, stopthe engine. Do not open the hood until theengine coolant has stopped running or thesteaming has stopped. If there is no visibleloss of engine coolant and no steam, leavethe engine running and check to be sure theengine cooling fan is operating. If the fan isnot running, turn the engine off.
4. Check to see if the water pump drive belt is missing. If it is not missing, check to see thatit is tight. If the drive belt seems to be satis-factory, check for engine coolant leaking fromthe radiator, hoses or under the car. (If the airconditioning had been in use, it is normal forcold water to be draining from it when youstop).
WARNING:While the engine is running, keep hair, hands,and clothing away from moving parts such asthe fan and drive belts to prevent injury.

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

POWER STEERING HOSES It is suggested that you check the power steer-
ing hose connections for fluid leakage daily. The power steering hoses should be replaced ifthere is severe surface cracking, pulling, scuff-ing or worn spots. Deterioration of the hosecould cause premature failure. G250A01A-AAT
FOR MORE INFORMATION ABOUT YOUR HYUNDAI
If you desire additional information about main- taining and servicing your Hyundai, you maypurchase a factory Shop Manual at your Hyundaidealer's parts department. This is the samemanual used by dealership technicians andwhile it is highly technical it can be useful inobtaining a better understanding of your carand how it works.

POWER STEERING FLUID LEVEL
The power steering fluid level should be checked
regularly.
To check the power steering fluid level, be sure
the ignition is "OFF", then check to make cer-tain that the power steering fluid level is be-tween the "MAX" and "MIN" level markings onthe fluid reservoir.
NOTE: Grinding noise from the power steering
pump may be heard immediately after the engine is started in extremely cold condi-tions (below - 20°F). If the noise stops dur-

Checking Condenser Cooling Fan
The condenser coolant fan should come on
automatically whenever the air conditioning is in operation. ing warm up, there is no abnormal functionin the system. It is due to a power steeringfluid characteristic in extremely cold condi-tions. Recommended Fluid Use PSF-3 type fluid NOTE: Do not start the engine when the power steering oil reservoir is empty.
G210B01A-AAT
Checking the Battery Keep the battery clean. Any evidence of corro-
sion around the battery posts or terminals shouldbe removed using a solution of household bak-ing soda and warm water. After the batteryterminals are dry, cover them with a light coat-ing of grease.
G220A01A-AAT
CHECKING ELECTRIC COOLING FANS 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 cool-ant temperature decreases the fan will auto-matically shut off. This is a normal condi-tion.
G220B01A-AAT
Checking Engine Cooling Fan The engine coolant fan should come on auto-
matically if the engine coolant temperature ishigh.
o Charge batteries only in a well ventilated
area.
o Do not permit flames, sparks or smoking in the area.
o Keep children away from the area.

About the Catalytic Converter
Exhaust gases passing through the catalytic
converter cause it to operate at very high tem- peratures. As a result, the introduction of largeamounts of unburned gasoline may cause it tooverheat and create a fire hazard. This can beavoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good condition. Ex- tremely high converter temperatures can result from improper operation of the electri-cal, ignition or fuel injection systems.
o If your engine stalls, pings, knocks, or is hard to start, take your car to your Hyundaidealer as soon as possible and have thedifficulty corrected.
o Avoid driving with a very low fuel level. If your run out of gasoline, it could cause theengine to misfire and result in excessiveloading of the catalytic converter.
o Avoid idling the engine for periods longer than 10 minutes.
o Your Hyundai should not be either pushed or pulled to get it started. This can cause thecatalytic converter to overload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper,leaves or rags. As these materials couldcome in contact with the catalytic converterand could cause a fire. o Do not touch the catalytic converter or any
other part of the exhaust system while theengine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai dealer is your best source of assistance.

o Lower-than-recommended tire pressures
cause uneven tread wear and poor han- dling.
o Higher-than-recommended tire pressures increase the chance of damage from im-pacts and cause uneven tread wear.
CAUTION: Always observe the following:
o Check pressures when the tires are cold. That is, after the car has been parked for at least three hours and hasn't been driv-en more than 1.6 km or one mile sincestarting up.
o Check the pressure of your spare tire each time you check the pressure ofother tires. I050A02GK-GAT
TIRE CHAINS
Tire chains, if necessary, should be installed onthe front wheels. Be sure that the chains areinstalled in accordance with the manufacturer'sinstructions. Refer to the following information. I060A02GK-GAT
TIRE ROTATION
I040A01S-GAT
SNOW TIRES If you equip your car with snow tires, they should be the same size and have the sameload capacity as the original tires. Snow tiresshould be installed on all four wheels; other-wise, poor handling may result. Snow tires should carry 28 kPa (4 psi) more air pressure than the pressure recommended forthe standard tires on the tire label on the driveside center pillar outer panel, or up to themaximum pressure shown on the tire sidewall whichever is less. Do not drive faster than 120 km/h (75 mph)when your car is equipped with snow tires. Tires should be rotated every 10,000 km (6,000miles). If you notice that tires are wearing un-evenly between rotations, have the car checkedby a Hyundai dealer so the cause may becorrected.After rotating, adjust the tire pressures and besure to check wheel nut torque. WARNING: Do not mix bias-ply and radial-ply tires un- der any circumstances. This may cause dan-gerous handling characteristics.
I060A01GK
To minimize tire and chain wear, do not contin-ue to use tire chains when they are no longerneeded. WARNING:
o When driving on roads covered with snow or ice, drive at less than 30 km/h (20 mph).
o Use tire chains less than 10mm (0.39 in.) for 16" and 17" tires.
o Avoid sudden stop and turns.
o Tighten firmly to avoid contact with the verticle body, if you have noise caused by chaws contacting the body, removethe chains for damage protection. 15", 16" Tire
