WHAT TO DO IN AN EMERGENCY
3-2
When jump starting, wear protective glasses and 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 with clear water for at least 15 minutes. Then promptly obtain medical attention. If you must be transported to an emergency facility, con- tinue to apply water to the affected area with a sponge or cloth.
o The gas produced by the battery during the
jump-start operation is highly explosive. Do not smoke or allow a spark or an open flame in the vicinity.
o The battery being used to provide the jump
start must be 12-volt. If you cannot determine that it is a 12-volt battery, do not attempt to use 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. First, attach one clamp of the jumper cable to the positive (+) post or cable of the discharged battery. Then attach the other end of the same cable to the positive (+) post or cable of the booster battery. Next, using the other cable, attach one clamp to the negative (-) post or cable of the booster battery. Then attach the other end of that cable to a solid metal part of the engine away from the battery. Do not connect the cable to any moving part.
4. Start the engine in the car with the booster
battery and let it run for a few minutes. This will help to assure that the booster battery is fully charged. During the jumping operation, run the engine in this vehicle at about 2,000 rpm.
5. Start the engine in the car with the discharged
battery using the normal starting procedure. After the engine starts, leave the jumper cables connected and let the engine run at fast idle or about 2,000 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 became discharged (because the lights were left on, etc.), have the charging system checked by your Hyundai dealer. D030A02A-AAT IF THE ENGINE OVERHEATS If your temperature gauge indicates overheating, you experience a loss of power, or hear loud pinging or knocking, the engine is probably too hot. 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, stop the engine. Do not open the hood until the engine coolant has stopped running or the steaming has stopped. If there is no visible loss of engine coolant and no steam, leave the engine running and check to be sure the engine cooling fan is operating. If the fan is not 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 that it is tight. If the drive belt seems to be satis- factory, check for coolant leaking from the radiator, hoses or under the car. (If the air conditioning had been in use, it is normal for cold water to be draining from it when you stop).

WHAT TO DO IN AN EMERGENCY 3-3
WARNING: While the engine is running, keep hair, hands, and clothing away from moving parts such as the fan and drive belts to prevent injury.
5. If the water pump drive belt is broken or
coolant is leaking out, stop the engine im- mediately and call the nearest Hyundai deal- er for assistance.
WARNING: Do not remove the radiator cap when the engine is hot. This can allow coolant to be blown out of the opening and cause serious burns. WARNING (Diesel only): Never work on injection system with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec- tors and high pressure pipes are subject to high pressure even after the engine stopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers should not move than 30cm closer to the ECU or wiring harness within the engine room while engine is running, since the high currents in the Common Rail system produce considerable magnetic fields. 2. The spare tire should only be used temporari-
ly and should be returned to the luggage compartment as soon as the original tire can be repaired or replaced.
3. Continuous use at speeds of over 80 km/h (50 mph) is not recommended.
4. As the temporary spare tire is specifically designed for your car, it should not be used on any other vehicle.
5. The temporary spare tire should not be used
on any other wheels, nor should standard tires, snow tires, wheel covers or trim rings be used with the temporary spare wheel. If such use is attempted, damage to these items or other car components may occur.
6. The temporary spare tire pressure should be
checked once a month while the tire is stored.
CAUTION:
o Do not use snow chains with your tempo- rary spare tire.
o Do not use more than one temporary spare tire at a time.
D040A01FC-GAT TEMPORARY SPARE TIRE The following instructions for the temporary spare tire should be observed:
1. Check inflation pressure as soon as possible
after installing the spare tire, and adjust to the specified pressure. The tire pressure should be periodically checked and maintained at the specified pressure while the tire is stored.
Inflation Pressure
Tire Size
T115/70R(D)15 420 kPa (60 psi)
Spare Tire Pressure
6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has returned to normal. Then, if the engine cool- ant has been lost, carefully remove the radia- tor cap and add engine coolant to bring the fluid level in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur- ther signs of overheating. If overheating hap- pens again, call a Hyundai dealer for assis- tance.
CAUTION: Serious loss of engine coolant indicates there is a leak in the cooling system and this should be checked as soon as possible by a Hyundai dealer.

D080C01FC D080D02A-AAT Emergency Towing For emergency towing when no commercial tow vehicle is available, attach a tow cable, chain or strap to one of the tie-down hooks under the front of your car. Do not attempt to tow your vehicle in this manner on any unpaved surface. This could result in serious damage to your car. Nor should towing be attempted if the wheels, drive train, axles, steering or brakes are dam- aged. Before towing, be sure the transaxle is in neutral and the key is in "ACC" (with the engine off) or in the "ON" position (with the engine running). A driver must be in the towed car to steer it and operate the brakes.

G350A01A-GAT
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. A thin film of oil is left on the cylinder wall when a piston moves downwards in thecylinder. High negative pressure generated
during 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 combustion gases 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. Theengine oil is more consumed under severedriving conditions such as high speeds and
frequent acceleration and deceleration thannormal driving condition.
G040A03FC-GAT
CHANGING THE OIL AND FILTER (GASOLINE ENGINE)
The engine oil and filter should be changed at
those intervals specified in the maintenance schedule 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.
3. Slide underneath the car and loosen the oil pan drain plug by turning it counterclock-wise with a wrench of the proper size. Besure that a drain pan is in position to catchthe oil as it drains out, then remove the drainplug.
WARNING:Be very careful when draining the engine oilas it may be hot enough to burn you!
4. When the oil has stopped draining, replace the drain plug using a new washer andretighten by turning it clockwise. Oil pan drain plug tightening torque: 1.6DOHC (European Community only: 4.0 ~4.5
kgf.m, Except European Comunity: 3.5 ~4.5 kgf.m) 1.8DOHC: 4.0 ~4.5 kgf.m
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.
