C070D02A-AAT Good Driving Practices
o Never take the car out of gear andcoast down a hill. This is extremely hazardous. Always leave the car in gear.
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 do this, engine braking will help slow the 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 muchbetter 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 into reverse, depress the clutch, movethe shift lever to neutral, wait three seconds, then shift to the reverse position.
C070E03A-GAT RECOMMENDED SHIFT POINTS The shift points as shown above are recommended for optimum fueleconomy and performance.
C070B01A-AAT Using the Clutch The clutch should be pressed all the way to the floor before shifting, thenreleased slowly. The clutch pedal should always be used after fully re- turning to the original position. Do notrest your foot on the clutch pedal while driving. This can cause unnecessary wear. Do not partially engage the clutchto hold the car on an incline. This causes unnecessary wear. Use the parking brake to hold the car on anincline. Do not operate the clutch pedal rapidly and repeatedly.

C090N02A-AAT Good Driving Practices
o Never move the gear selector leverfrom "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 andshift to a lower gear. When you do this, engine braking will help slow the 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. o Exercise extreme caution when driv-
ing on a slippery surface. Be espe-cially careful when braking, acceler- ating or shifting gears. On a slippery surface, an abrupt change in ve-hicle speed can cause the drive wheels to lose traction and the ve- hicle to go out of control.
o Turn the overdrive switch on for good fuel economy and smooth driv-ing. If engine braking is needed inthe "D" range or if repeated upshift- ing and downshifting between 3rd and 4th gear is needed when climb-ing a gentle slope, it is recommended that the overdrive switch be turned off. Turn the overdrive switch backon immediately afterward.
C090P01A-GAT Overdrive Switch When the overdrive switch is turned on, the transaxle will automatically upshift to the second, third and over-drive gears. When the overdrive switch is turned off, the transaxle will not upshift to the overdrive gear. For nor-mal driving, the selector lever should be left in the "D" position and the overdrive switch turned on.If you need to accelerate rapidly, press the accelerator pedal all the way to the floor. The transaxle will automaticallyshift to a lower gear, depending on the vehicle speed and load. HFC3023

16DRIVING FOR ECONOMY
C140A01A-GAT You can save fuel and get more kilo- meters from your car if you follow these suggestions:
o Drive smoothly. Accelerate at a moderate rate. Don't make "jack- rabbit" starts or full-throttle shiftsand maintain a steady cruising speed. Don't race between stop- lights. Try to adjust your speed tothat of the other traffic so you don't have to change speeds unneces- sarily. Avoid heavy traffic wheneverpossible. Always maintain a safe distance from other vehicles so you can avoidunnecessary braking. This also re- duces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel yourcar uses. Driving at a moderate speed, especially on the highway, isone of the most effective ways to reduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This can increase fuel consumptionand also increase wear on these components. In addition, driving with
gear (manual transaxle). If your caris facing downhill, turn the frontwheels into the curb to help keep the car from rolling. If your car is facing uphill, turn the front wheels awayfrom the curb to help keep the car from rolling. If there is no curb or if it is requiredby 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 accumulationof snow or ice around or near the rear brakes or if the brakes are wet. If there is a risk that the parkingbrake may freeze, apply it only tem- porarily while you put the gear se- lector lever in "P" (automatic) or infirst or reverse gear (manual transaxle) and block the rear wheels so the car cannot roll. Then releasethe parking brake.
o Do not hold the vehicle on the up-
grade with the accelerator pedal.This can cause the transmission to overheat. Always use the brake pedal or parking brake.
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 brakesoverheating and losing their effec- tiveness. It also increases the wear of the brake components.
o If a tire goes flat while you are driving, apply the brakes gently andkeep the car pointed straight aheadwhile you slow down. When you are moving slowly enough for it to be safe to do so, pull off the road andstop 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 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

your foot resting on the brake pedal may cause the brakes to overheat,which reduces their effectiveness and may lead to more serious con- sequences.
o Take care of your tires. Keep them inflated to the recommended pres-sure. Incorrect inflation, either toomuch or too little, results in unnec- essary tire wear. Check the tire pres- sures at least once a month.
o Be sure that the wheels are aligned correctly. Improper alignment canresult from hitting curbs or drivingtoo fast over irregular surfaces. Poor alignment causes faster tire wear and may also result in other prob-lems as well as greater fuel con- sumption.
o Keep your car in good condition. For better fuel economy and reducedmaintenance costs, maintain your car in accordance with the mainte-nance schedule in Section 5. If you drive your car in severe conditions, more frequent maintenance is re-quired (see Section 5 for details). o Keep your car clean. For maximum
service, your Hyundai should bekept clean and free of corrosive materials. It is especially important that mud, dirt, ice, etc. not be al-lowed to accumulate on the under- side of the car. This extra weight can result in increased fuel con-sumption and also contribute to cor- rosion.
o Travel lightly. Don't carry unneces- sary weight in your car. Weight re-duces fuel economy.
o Don't let the engine idle longer than
necessary. If you are waiting (andnot in traffic), turn off your engine and restart only when you're readyto go.
o Remember, your Hyundai does not
require extended warm-up. As soonas the engine is running smoothly, you can drive away. In very cold weather, however, give your enginea slightly longer warm-up period. o Don't "lug" or "over-rev" the engine.
Lugging is driving too slowly in toohigh a gear resulting in the engine bucking. If this happens, shift to a lower gear. Over-revving is racingthe engine beyond its safe limit. This can be avoided by shifting at the recommended speeds.
o Use your air conditioning sparingly. The air conditioning system is oper-ated by engine power so your fueleconomy is reduced when you use it.

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.
C160J01A-AAT Don't Let Ice and Snow Accumulate Underneath Under some conditions, snow and ice can build up under the fenders andinterfere with the steering. When driv- ing in severe winter conditions where this may happen, you should periodi-cally check underneath the car to be sure the movement of the front wheels and the steering components is notobstructed. C160K01A-AAT Carry Emergency Equipment Depending on the severity of the weather where you drive your car, you should carry appropriate emergency equipment. Some of the items youmay 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. C170A01A-AAT HIGHER SPEED MOTORING Pre-Trip Inspections 1. Tires: Adjust the tire inflation pressures to specification. 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 infla- tion pressure shown on the tires. 2. Fuel, engine coolant and en- gine 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.

21TRAILER OR VEHICLE TOWING
C190A02A-GAT 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, other types of vehicles, orapparatus may differ. Ask your Hyundai dealer for further details before towing.
CAUTION:
Do not do any towing with your car during 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.
! C190B01S-AAT Trailer Hitches Select the proper hitch and ball combi- nation, making sure that it's location iscompatible 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. C190C03S-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 Severe Usage Conditions" on page 5-7.
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. If the needle of the coolant tem-perature gauge moves across the dial towards "H" (HOT), pull over and stop as soon as it is safe todo so, and allow the engine to idle until it cools down. You may proceed once the engine hascooled sufficiently.

CAUTION:
If overheating should occur when towing, (temperature gauge reads near red zone), taking the following action may reduce or eliminate theproblem.
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 selection in park or neu- tral and idle the engine at a higherspeed.
!
8. When parking your car and trailer,
especially on a hill, be sure to follow all 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). In addition, 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 brake controller by hand to be sure the brakes 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 issecure, and that the lights and any trailer 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 efficiency. 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.
NOTE: When towing check transaxle fluid more frequently.

4IF THE ENGINE OVERHEATS
D030A02A-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"
(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 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 engine coolant and no steam, leave the engine running and check to be sure the enginecooling 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,
3. Attach the clamps of the jumper
cable in the exact location shown.First, attach one clamp of the jumper cable to the positive (+) post or cable of the discharged battery. Thenattach the other end of the same cable to the positive (+) post or cable of the booster battery. Next,using the other cable, attach one clamp to the negative (-) post or cable of the booster battery. Thenattach the other end of that cable to a solid metal part of the engine away from the battery. Do not con-nect the cable to any moving part.
4. Start the engine in the car with the
booster battery and let it run for afew minutes. This will help to as- sure that the booster battery is fully charged. During the jumping opera-tion, run the engine in this vehicle at about 2,000 rpm.
5. Start the engine in the car with the discharged battery using the nor-mal starting procedure. After the engine starts, leave the jumpercables connected and let the engine run 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 batterybecame discharged (because the lightswere left on, etc.), have the charging system checked by your Hyundai dealer.

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 be draining from it when you stop).
WARNING (Diesel only):
Never work on injection system with engine running or within 30 sec- onds after shutting off engine. Highpressure pump, rail, injectors and high pressure pipes are subject to high pressure even after the enginestopped. The fuel jet produced by fuel leaks may cause serious in- jury, if it touch the body. Peopleusing pacemakers should not move than 30cm closer to the ECU or wiring harness within the engine 5. If the water pump drive belt is bro-
ken or coolant is leaking out, stopthe engine immediately and call the nearest Hyundai dealer for assis- tance. CAUTION:
Serious loss of engine coolant indi- cates there is a leak in the cooling system and this should be checkedas soon as possible by a Hyundai dealer.
room while engine is running, since the high currents in the CommonRail system produce considerable magnetic fields.
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 hasbeen lost, carefully add coolant to the reservoir (page 6-14) to bring the fluid level in the reservoir up tothe halfway mark.
WARNING:
While the engine is running, keephair, hands, and clothing away from moving parts such as the fan and drive belts to prevent injury.
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. 7. Proceed with caution, keeping alert
for further signs of overheating. If overheating happens again, call a Hyundai dealer for assistance.
