HGK131A
The tachometer registers the speed of your en- gine in revolutions per minute (rpm). CAUTION: The engine should not be raced to such aspeed that the needle enters the red zone onthe tachometer face. This can cause severeengine damage and may void your warranty.
WARNING:Never remove the radiator cap when the en-gine is hot. The engine coolant is under pres-sure and could erupt and cause severe burns.Wait until the engine is cool before removingthe radiator cap. The needle on the engine coolant temperature gauge should stay in the normal range. If itmoves across the dial to "H" (Hot), pull over andstop as soon as possible and turn off the engine.Then open the hood and, after the engine hascooled, check the coolant level and the waterpump drive belt. If you suspect cooling systemtrouble, have your cooling system checked by aHyundai dealer as soon as possible.

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.

CHECKING AND CHANGING THE EN- GINE COOLANT
WARNING: Do not remove the radiator cap when the
engine is hot. When the engine is hot, the engine coolant is under pressure and mayerupt through the opening if the cap isremoved. You could be seriously burned ifyou do not observe this precaution. Do notremove the radiator cap until the radiator iscool to the touch. G050B01A-AAT
Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant shouldbe compatible with aluminum engine parts.Additional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof engine coolant to prevent freezing and corro-sion. Never allow the concentration of anti-freeze to exceed the 60% level or go below the35% level, or damage to the cooling systemmay result. For proper concentration when add-ing or replacing the engine coolant, refer to thefollowing table.
HGK187
35% 40%50%60%
G050C01A-AAT
To Check the Coolant Level The coolant level can be seen on the side of the plastic coolant reservoir. The level of the cool-ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cool.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect forcoolant leaks and recheck the fluid level fre-quently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason.
7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-ter 9 for engine oil capacity.
8. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It is sug-gested that it be placed in a sealed containerand taken to a service station for maybereclaimation. Do not pour the oil on theground or put it in with the household trash.
WARNING: Used motor oil may cause irritation or can-
cer of the skin if left in contact with the skin for prolonged periods of time. Wash yourhands thoroughly with soap and warm wa-ter as soon as possible after handling usedoil.

To Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance schedule in Section 5.
NOTE: Engine coolant can damage the finish of
your car. If you spill engine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park- ing brake and remove the radiator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer's directions on the enginecoolant container, add the appropriate quan-tity of engine coolant to the radiator.
4. Turn the radiator cap counterclockwise with- out pressing down on it, until it stops. Thisrelieves any pressure remaining in the cool-ing system. And remove the radiator cap bypushing down and turning counterclockwise. Now fill the radiator with clean demineral- ized or distilled water. Continue to add cleandemineralized or distilled water in small quan-tities until the fluid level stays up in theradiator neck. DOHC1.0~1.1 mm (0.039 ~ 0.043 in.)
