1. If your car has an automatic transaxle, be sure the gear selector lever is in "N" or "P" and the emergency brake is set. 2. Check the battery connections to be sure
they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you operate the starter, thebattery is discharged.
4. Check the starter connections to be sure they are securely tightened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump Starting" on the follow-ing pages.
D010C01A-AAT If Engine Turns Over Normally but Does Not Start
1 Check fuel level.
2 With the key in the off position, Check all connectors at ignition coils and spark plugs.Reconnect any that may be disconnected orloose.
3 Check the fuel line in the engine compart- ment.
4 If engine still refuses to start, call a Hyundai dealer or seek other qualified assistance.
D010D01A-AAT If Engine Stalls While Driving
1. Reduce your speed gradually, keeping a straight line. Move cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your vehicle will not start, contact a Hyundai dealer or seekother qualified assistance. D020A02A-AAT JUMP STARTING

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.

Replacing Accessory Fuse The fuse box for the lights and other electrical accessories will be found low on the dashboardon the driver's side. Inside the box you will find alist showing the circuits protected by each fuse. If any of your car's lights or other electrical
accessories stop working, a blown fuse couldbe the reason. If the fuse has burned out, youwill see that the metal strip inside the fuse hasburned through. If you suspect a blown fuse,follow this procedure:
1. Turn off the ignition and all other switches.
2. Open the fuse box and examine each fuse. Remove each fuse by pulling it toward you (a small "fuse puller" tool is contained in thefuse box to simplify this operation).
3. Be sure to check all other fuses even if you find one that appears to have burned out.

CHECKING AND REPLACING FUSES Replacing a Fusible Link
A fusible link will melt if the electrical circuits
from the battery are ever overloaded, thus pre- venting damage to the entire wiring harness.(This could be caused by a short in the systemdrawing too much current.) If this ever happens,have a Hyundai dealer determine the cause,repair the system and replace the fusible link.The fusible links are located in a relay box foreasy inspection.
CAUTION: When replacing a fusible link, never use
anything but a new fusible link with the same or lower amperage rating. Never use apiece of wire or a higher-rated fusible link.This could result in serious damage andcreate a fire hazard.
