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.

WHAT TO DO IN AN EMERGENCY 3-3
5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the engine immediately and call the nearest Hyundaidealer for assistance.
WARNING:Do not remove the radiator cap when theengine is hot. This can allow coolant to beblown out of the opening and cause seriousburns.
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 add coolant to thereservoir (page 6-8) to bring the fluid level inthe 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 thereis a leak in the cooling system and this shouldbe checked as soon as possible by a Hyundaidealer. 2. The spare tire should only be used temporari-
ly and should be returned to the luggagecompartment as soon as the original tire canbe 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 onany other vehicle.
5. The temporary spare tire should not be used on any other wheels, nor should standardtires, snow tires, wheel covers or trim ringsbe used with the temporary spare wheel. Ifsuch use is attempted, damage to theseitems or other car components may occur.
6. The temporary spare tire pressure should be checked once a month while the tire is stored.
D040A01GK-GAT TEMPORARY SPARE TIREThe following instructions for the temporary spare tire should be observed:
1. Check inflation pressure as soon as practical
after installing the spare tire, and adjust to the specified pressure. The tire pressure shouldbe periodically checked and maintained atthe specified pressure while the tire is stored.
Spare Tire Pressure 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.

To Check the Oil Level G030D01A-GAT
Adding Oil
Before checking the oil, warm up the engine to
the normal operating temperature and be sure it is parked on level ground. Turn the engine off.
Wait five minutes, then remove the dipstick,
wipe it off, fully reinsert the dipstick and with-draw it again. Then note the highest level the oilhas reached on the dipstick. It should be be-tween the upper ("FULL") and lower ("LOW")range. 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 counter- clockwise.
2. Add oil, then check the level again. Do not overfill.
3. Replace the cap by turning it clockwise.
The distance between the "F" and "L" marks is
equal to about 1 liter of oil.HGK211
DOHC V6 DOHC V6
See the lubrication chart on the page 9-3. NOTE:
o The use of a 5W-20 multi grade oil is not recommended for sustained high speed use.
o When replacing or adding the oil, below SAE 10W-30 is recommended. Using a high viscosity oil of SAE 15W-40 and over makes malfunction of CVVTengine when the engine is cool.
