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 underneath the hood, stop theengine. 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 surethe engine cooling 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.

WHAT TO DO IN AN EMERGENCY
5SPARE 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 may result incoolant being 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. 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.

2. The spare tire should only be used temporarily 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 spe-
cifically designed for your car, it should not be used on any other vehicle.
D040A01MC-GAT TEMPORARY SPARE TIRE (If Installed) The following instructions for the tem- porary spare tire should be observed:
1. Check inflation pressure as soon as
practical after installing the spare tire, and adjust to the specified pres- sure. The tire pressure should be periodically checked and maintainedat the specified pressure while the tire is stored.

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.

!!WARNING:
The cooling fan is controlled by en- gine coolant temperature and may sometimes operate even when the engine is not running. Use extremecaution when working near the blades of the cooling fan, so that you are not injured by a rotating fan blade. As theengine coolant temperature decreas- es, the fan will automatically shut off. This is a normal condition. WARNING (
Diesel only):
Never work on injection system withengine running or within 30 seconds after shutting off engine. High pres- sure pump, rail, injectors and highpressure pipes are subjected to high pressure even after the engine has been switched off. The fuel jet pro-duced by fuel leaks may cause seri- ous injury, if it contacts with the body. People using pacemakersshould not move closer than 30cm to the ECU or wiring harness within the engine room with the engine run-ning, since the high currents in the Common Rail system produce con- siderable magnetic fields.

Fluid level should be within "HOT" range
3. Confirm if the fluid level is in the “HOT” range on the level gauge. If the fluid level is lower, add the speci- fied fluid from the fill hole. If the fluidlevel is higher, drain the fluid from the drain hole.
4. If the fluid level is checked in cold
condition[fluid temperature 20~30°C(68~86°F)], add the fluid to the “COLD” line and then recheck the fluid levelaccording to the above step 2.

G140B01A-AAT Checking the Air Conditioning Operation
1. Start the engine and let it run at afast idle for several minutes with the air conditioning set at the maximum cold setting.
2. If the air coming out of the in-dash vents is not cold, have the air condi-tioning system inspected by yourHyundai dealer.
G140C01A-AAT Lubrication To lubricate the compressor and the seals in the system, the air conditioning should be run for at least 10 minuteseach week. This is particularly important during cool weather when the air condi- tioning system is not otherwise in use.
! CAUTION:
Running the air conditioning sys- tem for extended periods of time with a low refrigerant level may damage the compressor.
AIR CONDITIONING CARE
G140A01A-AAT Keeping the Condenser Clean The air conditioning condenser (and engine radiator) should be checkedperiodically for accumulation of dirt, dead insects, leaves, etc. These can interfere with maximum cooling effi-ciency. When removing such accumu- lations, brush or hose them away care- fully to avoid bending the cooling fans.CHECKING THE CLUTCH FLUID
G130A01A-AAT (If Installed) To Check the Clutch Fluid The clutch fluid level in the master cylinder should be checked when per- forming other under hood services. Thesystem should be checked for leakage at the same time. Check to make certain that the clutchfluid level is between the "MAX" and "MIN" level markings on the fluid reser- voir. Fill as required. Fluid loss indi-cates a leak in the clutch system which should be inspected and repaired im- mediately. Consult your Hyundai dealer.

o When lifting a plastic-cased bat-
tery, excessive pressure on the case may cause battery acid to leak, resulting in personal injury.Lift with a battery carrier or with your hands on opposite corners.
o Never attempt to charge the bat-
tery when the battery cables areconnected.
o The electrical ignition system
works with high voltage.Never touch these components with the engine running or the ignition switched on.
CHECKING ELECTRIC COOLING FANS
!
G220B01A-AAT Checking Engine Cooling Fan The engine cooling fan should come on automatically if the engine coolant tem-perature is high. G220C01TB-GAT Checking Condenser Cooling Fan When the air conditioning is in opera- tion, the condenser cooling fan comeson automatically to be controlled by ECU.G220A01A-AAT
WARNING:
The cooling fan is controlled by en- gine coolant temperature and may sometimes operate even when the engine is not running. Use extremecaution when working near the blades of the cooling fan, so that you are not injured by a rotating fanblade. As the engine coolant temper- ature decreases the fan will automat- ically shut off. This is a normal con-dition.
POWER STEERING FLUID LEVEL
G230A01MC-GAT (If Installed) 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 certain that the power steering fluid level is between the "MAX"and "MIN" level markings on the fluid reservoir.
