2003 Hyundai Grandeur overheating

1- 92 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 windowsclosed to keep hot air out.
o When moving slowly, as in heavy
traffic, shift to a lower gear. Thisincreases engine speed, which in turn increases the speed of the air conditioning 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 conditioningonce every month for a few min- utes. This will help circulate the lubricants and keep your system inpeak operating condition.

2- 14 DRIVING YOUR HYUNDAI
C140A01A-AAT DRIVING FOR ECONOMY You can save fuel and get more miles from your car if you follow these sug-gestions:
o Drive smoothly. Accelerate at a
moderate rate. Don't make "jack- rabbit" starts or full-throttle shifts and maintain a steady cruisingspeed. Don't race between stop- lights. Try to adjust your speed to that of the other traffic so you don'thave to change speeds unneces- sarily. Avoid heavy traffic whenever possible. Always maintain a safedistance from other vehicles so you can avoid unnecessary braking. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel yourcar uses. Driving at a moderatespeed, especially on the highway, is one of the most effective ways to reduce fuel consumption.
If there is no curb or if it is required by other conditions to keep the car from rolling, block the wheels.
o Under some conditions your park- ing brake can freeze in the engagedposition. This is most likely to hap-pen when there is an accumulation of snow or ice around or near the rear brakes or if the brakes are wet.If there is a risk that the parking brake may freeze, apply it only tem- porarily while you put the gear se-lector lever in "P" (automatic) or in first or reverse gear (manual transaxle) and block the rear wheelsso the car cannot roll. Then release the parking brake.
o Do not hold the vehicle on the up- grade with the accelerator pedal.This can cause the transaxle to overheat. Always use the brakepedal or parking brake.
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 ahead while 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.
o If your car is equipped with an auto- matic transaxle, don't let your carcreep forward. To avoid creeping forward, keep your foot firmly on the
brake pedal when the car is stopped.
o Use caution when parking on a hill.
Engage the parking brake and placethe gear selector lever in "P" (auto- matic transaxle) or in first or reverse
gear (manual transaxle). If your caris facing downhill, turn the front
wheels into the curb to help keep the car from rolling. If your car is facing
uphill, turn the front wheels away from the curb to help keep the car from rolling.

C190B01S-AAT Trailer 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 uniformly throughout the chassis. The hitch should be bolted securely to the car and installed by a qualified technician. DO NOT USE A HITCHDESIGNED FOR TEMPORARY IN- STALLATION AND NEVER USE ONE THAT ATTACHES ONLY TO THEBUMPER.
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 to drive 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 Vehicles to determine their legal requirements.Since laws vary from province to prov- ince the requirements for towing trail- ers, cars, or other types of vehicles orapparatus may differ. Ask your Hyundai dealer 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 this caution may result in serious en- gine or transaxle damage.

C170A01A-AAT HIGH SPEED MOTORING Pre-Trip Inspections 1. Tires: Adjust the tire inflation pressures to specification. Low tire inflation pres-sures will result in overheating and possible failure of the tires. Avoid using worn or damaged tireswhich may result in reduced traction or tire 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 more fuel than urban motoring. Do not forget tocheck both engine coolant and engine oil. 3. Drive belt: A loose or damaged drive belt may result in overheating of the engine.

C190F01Y-GAT Trailer or Vehicle Towing Tips
1. Before towing, check hitch and
safety chain connections as well as proper operation of the trailer run- ning lights, brake lights, and turn signals.
2. Always drive your vehicle at a mod- erate speed (Less than 100 km/h)
3. Trailer towing requires more fuel than normal conditions.
4. To maintain engine braking effi-
ciency and electrical charging per-formance, do not use fifth gear (manual transaxle).
5. Always secure items in the trailer to
prevent load shift while driving.
6. Check the condition and air pres-
sure of all tires on the trailer and your car. Low tire pressure can seriously affect the handling. Also check the spare tire. 10.During your trip, check occasion-
ally to be sure that the load issecure, 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 could cause the brakes to overheat, re- sulting in reduced braking efficien-cy.
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 lowergear 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.
7. The vehicle/trailer combination is
more affected by crosswind andbuffeting.When being passed by a large ve- hicle, keep a constant speed and steer straight ahead. If there is toomuch wind buffeting, slow down to get out of the other vehicle's air turbulence.
8. When parking your car and trailer, especially on a hill, be sure to followall the normal precautions. Turnyour front wheel into the curb, set the parking brake firmly, and put the transaxle in 1st or Reverse(manual) or Park (automatic). In addition, place wheel chocks at each 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 the brakes are working. This lets you check your electrical connection atthe same time.

NOTE: When towing, check transaxle fluid more frequently.
CAUTION:
If overheating should occur whentowing, (temperature gauge reads near red zone), taking the followingaction may reduce or eliminate the problem.
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 neu-tral and 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. (If the air conditioning had been in use,it is normal for cold water to be draining from it when you stop).
WARNING:
While the engine is running, keep hair, hands, and clothing away frommoving parts such as the fan and drive belts to prevent injury.
5. If the water pump drive belt is bro- ken or engine coolant is leaking out, stop the engine immediately and call the nearest Hyundai dealer for assistance.
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. 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" (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. Do not open the hood until the enginecoolant has stopped running or the steaming has stopped. If there is no visible loss of coolant and no steam,leave the engine running and check to be sure the engine cooling fan is operating. 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 the drive belt seems to be satisfactory, 6. If you cannot find the cause of the
overheating, wait until the engine temperature has returned normal.Then, if the engine coolant has been lost, carefully add engine coolant to the reservoir (page 6-9) 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.
CAUTION:
Serious loss of engine coolant indi-cates there is a leak in the cooling system and this should be checked as soon as possible by a Hyundaidealer.
