engine overheat Hyundai Grandeur 2002 Owner's Manual

1- 90 FEATURES OF YOUR HYUNDAI
B740D01Y-AAT Operation Tips
o If the interior of the car is hot when
you first get in, open the windows for a few minutes to expel the hot air.
o When you are using the air condi-
tioning system, keep all windows closed to keep hot air out.
o When moving slowly, as in heavy traffic, shift to a lower gear. This increases engine speed, which inturn increases the speed of the airconditioning compressor.
o On steep grades, turn the air condi-
tioning off to avoid the possibility ofthe engine overheating.
o During winter months or in periods when the air conditioning is not usedregularly, run the air conditioning once every month for a few min- utes. This will help circulate thelubricants and keep your system inpeak operating condition.

C070D02A-AAT Good Driving Practices
o Never take the car out of gear and
coast down a hill. This is extremely hazardous. Always leave the car ingear.
o Don't "ride" the brakes. This can cause them to overheat and mal-function. Instead, when you are driv-ing down a long hill, slow down andshift to a lower gear. When you dothis, engine braking will help slowthe car.
o Slow down before shifting to a lower
gear. This will help avoid over-rev-ving the engine, which can causedamage.
o Slow down when you encounter
cross winds. This gives you much better control of your car.
o Be sure the car is completely stopped
before you attempt to shift into re- verse. The transaxle can be dam-aged if you do not. To shift intoreverse, depress the clutch, move the shift lever to neutral, wait three seconds, then shift to the reverseposition.
C070B01A-AAT Using the Clutch The clutch should be pressed all the way to the floor before shifting, thenreleased slowly. The clutch pedalshould always be used after fully re- turning to the original position. Do not rest your foot on the clutch pedal whiledriving. This can cause unnecessarywear. Do not partially engage the clutchto hold the car on an incline. Thiscauses unnecessary wear. Use the parking brake to hold the car on an incline. Do not operate the clutch pedalrapidly and repeatedly. CAUTION:
When downshifting from fifth gearto fourth gear, caution should betaken not to inadvertently press thegear lever sideways in such a man-ner that second gear is engaged. Such a drastic downshift may cause the engine speed to increase to thepoint that the tachometer will enterthe red-zone. Such over-revving ofthe engine may possibly cause en-gine damage.

C090H01L-GAT NOTE:
o For smooth and safe operation,
depress the brake pedal when shifting from "Neutral" positionor "Park" position to a forward orreverse gear.
o The ignition key must be in the "ON" position and the brake pedalfully depressed in order to movethe shift lever from the "P" (Park)position to any of the other posi-tions.
o It is always possible to shift from "R", "N", "D" position to "P" po-sition. The vehicle must be fullystopped to avoid transaxle dam-age. C090I01L-GAT
CAUTION:
o Shift into "R" and "P" position only when the vehicle has com-pletely stopped.
o Do not accelerate the engine in reverse or any of the forwardpositions with the brakes applied.
o Always apply the footbrake when
shifting from "P" or "N", to "R" or"D" position.
o Do not use the "P" (Park) posi- tion in place of the parking brake.Always set the parking brake,shift the transaxle into "P" (Park)position and turn off the ignitionwhen you leave the vehicle, evenmomentarily. Never leave the ve- hicle unattended while the en- gine is running.
o Check the automatic transaxle fluid level regularly, and add fluidas necessary.
o See the maintenance schedule for the proper fluid reco-mendation. C090N01Y-AAT Good Driving Practices
o Never move the gear selector lever
from "P" or "N" to any other position with the accelerator pedal de-pressed.
o Never move the gear selector lever into "P" when the vehicle is in mo-tion.
o Be sure the car is completely stopped
before you attempt to shift into "R".
o Never take the car out of gear and
coast down a hill. This may be ex- tremely hazardous. Always leave the car in gear when moving.
o Do not "ride" the brakes. This can cause them to overheat and mal-function. Instead, when you are driv-ing down a long hill, slow down and shift to a lower gear. When you do this, engine braking will help slowthe car.
o Slow down before shifting to a lower gear. Otherwise, the lower gear maynot be engaged.
o Always use the parking brake. Do
not depend on placing the transaxlein "P" to keep the car from moving.

NOTE:
1) When TCS illuminates, traction
control is automatically deacti- vated for safety.
2) This warning function is not pro- vided when in the TCS-OFF mode.
3) When the engine starts, a click is
heard from the engine compart-ment; however, this is only thesound of traction control beingchecked.
4) When moving out of the mud or
fresh snow, pressing the accel-erator pedal may not cause theengine speed to increase.
C300D02L-GAT Indicator and Warning The indicator should illuminate when
the ignition key is turned ON or START but should go out after three seconds. If the indicators do not illuminate or goout after three seconds, have themchecked by an authorized dealer. Should there be any unusual condi- tions in the device, TCS illuminates asa warning.If TCS illuminates, pull your car to asafe place and stop the engine.Then, start the engine again to check if the TCS indicator goes out. If the indicator do not go out after three seconds even after the engine hasbeen started, have your car checkedby an authorized Hyundai dealer. C130A01A-AAT GOOD BRAKING PRACTICES
WARNING:
Nothing should be carried on top of the cargo area cover behind therear seat. If there were an accidentor a sudden stop, such objectscould move forward and cause dam- age to the vehicle or injure the oc- cupants.
o After being parked, check to be sure the parking brake is not engaged and that the parking brake indicator light is out before driving away.
o Driving through water may get the brakes wet. They can also get wet when the car is washed. Wet brakescan be dangerous! Your car will notstop as quickly if the brakes are wet. Wet brakes cause the car to pull toone side. To dry the brakes, applythe brakes lightly until the braking
action returns to normal, taking careto keep the car under control at all times. If the braking action does not return to normal, stop as soon as it
is safe to do so and call your Hyundaidealer for assistance.
o Don't coast down hills with the car out of gear. This is extremely haz- ardous. Keep the car in gear at all times, use the brakes to slow down,then shift to a lower gear so thatengine braking will help you main-tain a safe speed.
o Don't "ride" the brake pedal. Rest- ing your foot on the brake pedalwhile driving can be dangerous be-cause it can result in the brakes
overheating and losing their effec-tiveness. It also increases the wearof the brake components.
o If a tire goes flat while you are
driving, apply the brakes gently and
keep the car pointed straight aheadwhile you slow down. When you are
moving slowly enough for it to besafe to do so, pull off the road and stop in a safe place.

C160I01A-AAT Don't Let Your Parking Brake Freeze Under some conditions your parking brake can freeze in the engaged posi-tion. This is most likely to happenwhen there is an accumulation of snow or ice around or near the rear brakes or if the brakes are wet. If there is a riskthe parking brake may freeze, apply itonly temporarily while you put the gearselector lever in "P" (automatic) or infirst or reverse gear (manual transaxle) and block the rear wheels so the car cannot roll. Then release the parkingbrake.
C160H01A-AAT Use Approved Anti-Freeze in Window Washer System To keep the water in the window washer system from freezing, add an approvedanti-freeze solution in accordance withinstructions on the container. Windowwasher anti-freeze is available fromHyundai dealers and most auto parts outlets. Do not use engine coolant or other types of anti-freeze as thesemay damage the finish.
C160K01A-AAT Carry Emergency Equipment Depending on the severity of the weather where you drive your car, youshould carry appropriate emergency equipment. Some of the items you may want to carry include tire chains,tow straps or chains, flashlight, emer-gency flares, sand, a shovel, jumpercables, a window scraper, gloves,ground cloth, coveralls, a blanket, etc.
C160J01A-AAT Don't Let Ice and Snow Accumu- late Underneath Under some conditions, snow and ice can build up under the fenders andinterfere with the steering. When driv-ing in severe winter conditions wherethis may happen, you should periodi- cally check underneath the car to be sure the movement of the front wheelsand the steering components is notobstructed.
C170A01A-AAT HIGH SPEED MOTORING Pre-Trip Inspections 1. Tires: Adjust the tire inflation pressures tospecification. Low tire inflation pres-sures will result in overheating andpossible failure of the tires. Avoid using worn or damaged tires which may result in reduced traction ortire failure. NOTE: Never exceed the maximum tire in- flation pressure shown on the tires. 2. Fuel, engine coolant and engine oil: High speed travel consumes 1.5 timesmore fuel than urban motoring. Do notforget to check both engine coolantand engine oil. 3. Drive belt: A loose or damaged drive belt mayresult in overheating of the engine.

C190C01Y-GAT Trailer Brakes If your trailer is equipped with a braking system, make sure it conforms to fed-eral and/or local regulations and that it
is properly installed and operating cor-rectly. NOTE: If you tow a trailer or vehicle, your car will require more frequent main-tenance due to the additional load.See "Maintenance Under SevereUsage Conditions" on page 5-6.
CAUTION:
o Never connect a trailer brake sys- tem directly to the vehicle brakesystem.
o When towing a trailer on steep grades (in excess of 12%) pay
close attention to the engine cool- ant temperature gauge to ensure
the engine does not overheat. Ifthe needle of the coolant tem-
perature gauge moves across thedial towards "H" (HOT), pull over and stop as soon as it is safe to
C190B01S-AATTrailer Hitches Select the proper hitch and ball combi- nation, making sure that it's location is compatible with that of the trailer or vehicle being towed.Use a quality non-equalizing hitch whichdistributes the tongue load uniformlythroughout the chassis. The hitch should be bolted securely to the car and installed by a qualifiedtechnician. DO NOT USE A HITCHDESIGNED FOR TEMPORARY IN-STALLATION AND NEVER USE ONETHAT ATTACHES ONLY TO THE BUMPER.
C180A01A-AAT USE OF LIGHTS Check your lights regularly for correct operation and always keep them clean.When driving during the day in condi-tions of poor visibility, it is helpful todrive with headlights on low beam. This enables you to be seen as well as to see. C190A01A-GAT TRAILER OR VEHICLE TOWING If you are considering towing with your car, you should first check with your Province Department of Motor Vehiclesto determine their legal requirements.Since laws vary from province to prov-ince the requirements for towing trail- ers, cars, or other types of vehicles or apparatus may differ. Ask your Hyundaidealer for further details before towing.
CAUTION:
Do not do any towing with your carduring its first 2,000 km (1,200 miles)in order to allow the engine to prop-erly break in. Failure to heed thiscaution may result in serious en- gine or transaxle damage.

14.When going down a hill, shift into a
lower gear and use the engine brak- ing effect.When ascending a long grade,downshift the transaxle to a lower gear and reduce speed to reduce chances of engine overloading and/or overheating.
15.If you have to stop while going uphill, do not hold the vehicle inplace by pressing on the accelera- tor. This can cause the automatic transaxle to overheat. Use the park-ing brake or footbrake.
NOTE: When towing, check transaxle fluid more frequently.
CAUTION:
If overheating should occur whentowing, (temperature gauge readsnear red zone), taking the followingaction may reduce or eliminate theproblem.
get out of the other vehicle's airturbulence.
8. When parking your car and trailer,
especially on a hill, be sure to followall the normal precautions. Turn your front wheel into the curb, set the parking brake firmly, and putthe transaxle in 1st or Reverse(manual) or Park (automatic). Inaddition, place wheel chocks ateach of the trailer's tires.
9. If the trailer has electric brakes,
start your vehicle and trailer mov-ing, and then apply the trailer brakecontroller by hand to be sure thebrakes are working. This lets youcheck your electrical connection at the same time.
10.During your trip, check occasion- ally to be sure that the load is secure, and that the lights and anytrailer brakes are still working.
11.Avoid jerky starts, sudden accel- eration or sudden stops.
12.Avoid sharp turns and rapid lane changes.
13.Avoid holding the brake pedal down too long or too frequently. This couldcause the brakes to overheat, re- sulting in reduced braking efficien- cy. 1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going
uphill.
4. While in stop and go traffic, place the gear selector in park or neutraland idle the engine at a higher speed.

3- 4 WHAT TO DO IN AN EMERGENCY
check for coolant leaking from the radiator, hoses or under the car. (Ifthe 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 frommoving parts such as the fan anddrive belts to prevent injury.
5. If the water pump drive belt is bro- ken or engine coolant is leaking out, stop the engine immediately andcall the nearest Hyundai dealer forassistance.
WARNING:
Do not remove the radiator cap whenthe engine is hot. This can allowcoolant to be blown out of the open-ing and cause serious burns.
D030A01A-AAT IF THE ENGINE OVERHEATS If your temperature gauge indicates overheating, you experience a loss ofpower, 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 the hood, stop the engine. Donot open the hood until the engine coolant has stopped running or the steaming has stopped. If there is novisible loss of coolant and no steam,leave the engine running and checkto be sure the engine cooling fan isoperating. 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 thedrive belt seems to be satisfactory, 6. If you cannot find the cause of the
overheating, wait until the enginetemperature has returned to nor-mal. Then, if the engine coolant hasbeen lost, carefully remove the ra- diator cap and add engine coolant to bring the fluid level in the reservoirup to the halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. Ifoverheating happens again, call a Hyundai dealer for assistance.
CAUTION:
Serious loss of engine coolant indi- cates there is a leak in the coolingsystem and this should be checkedas soon as possible by a Hyundai dealer.

EMISSION CONTROL SYSTEMS 7- 3
WARNING:
o Use unleaded fuel only.
o Maintain the engine in good operating condition. Extremelyhigh catalytic converter tempera- tures can result from improper operation of the electrical, igni-tion or multiport electronic fuel injection.
o If your engine stalls, pings, knocks, or is hard to start, haveyour Hyundai dealer inspect and repair the problem as soon as possible.
o Avoid driving with a very low fuel level. Running out of gaso-line may cause the engine to misfire and result in damage tothe catalytic converter.
o Avoid idling the engine for peri- ods longer than 10 minutes.
o The vehicle should not be pushed or pulled to get started.This may cause the catalytic con- verter to overheat and create a fire hazard.
H020A01A-AAT
CATALYTIC CONVERTER
HXGS509
All Hyundai vehicles are equippedwith a monolith type three-way cata-lytic converter to reduce the carbon monoxide, hydrocarbons and nitro- gen oxides contained in the exhaustgas. Exhaust gases passing through the catalytic converter may cause it to operate at a very high temperature.The introduction of large amounts of unburned gasoline into the exhaust may cause the catalytic converter tooverheat and create a fire hazard. This risk may be reduced by observ- ing the following:
Catalytic Converter o Do not touch the catalytic con-
verter or any other part of the exhaust system while the cata-lytic converter is hot. Shut off the engine, wait for at least one hour before touching the cata-lytic converter or any other part of the exhaust system.
o Remember that your Hyundai dealer is your best source of assistance.
o Do not stop your Hyundai over any combustible material suchas grass, paper, leaves or rags.These materials might contact the hot catalytic converter and a fire might result.
