SMOOTH CORNERING
Avoid braking or gear changing in corners, espe- cially when roads are wet. Ideally, corners should always be taken under gentle acceleration. If you follow these suggestions, tire wear will be held to a minimum.
curbs or driving too fast over irregular surfac- es. Poor alignment causes faster tire wear and may also result in other problems as well as greater fuel consumption.
o Keep your car in good condition. For better
fuel economy and reduced maintenance costs, maintain your car in accordance with the maintenance schedule in Section 5. If you drive your car in severe conditions, more frequent maintenance is required (see Sec- tion 5 for details).
o Keep your car clean. For maximum service, your Hyundai should be kept clean and free of corrosive materials. It is especially important that mud, dirt, ice, etc. not be allowed to accumulate on the underside of the car. This extra weight can result in increased fuel con- sumption and also contribute to corrosion.
o Travel lightly. Don't carry unnecessary weight
in your car. Weight reduces fuel economy.
o Don't let the engine idle longer than neces-
sary. If you are waiting (and not in traffic), turn off your engine and restart only when you're ready to go.
o Remember, your Hyundai does not require
extended warm-up. As soon as the engine is running smoothly, you can drive away. In very cold weather, however, give your engine a slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too high a gear result- ing in the engine bucking. If this happens, shift to a lower gear. Over-revving is racing the engine beyond its safe limit. This can be C160A01A-AAT WINTER DRIVING The more severe weather conditions of winter result in greater wear and other problems. To minimize the problems of winter driving, you should follow these suggestions: C160B01A-GAT Snowy or Icy ConditionsTo drive your vehicle in deep snow, it may be necessary to use snow tires or to install tire chains on your tires. If snow tires are needed, it is necessary to select tires equivalent in size and type to the original equipment tires. Failure to do so may adversely affect the safety and handling of your car. Speeding, rapid acceleration, sud- den brake applications, and sharp turns are potentially very hazardous practices. During
C140A01A-GAT DRIVING FOR ECONOMY You can save fuel and get more kilometers 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 shifts and maintain a steady cruising speed. Don't race between stoplights. Try to adjust your speed to that of the other traffic so you don't have to change speeds unneces- sarily. Avoid heavy traffic whenever possible. Always maintain a safe distance from other vehicles so you can avoid unnecessary brak- ing. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel your car uses. Driving at a moderate speed, especially on the high- way, is one of the most effective ways to reduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This
can increase fuel consumption and also in- crease wear on these components. In addi- tion, driving with your foot resting on the brake pedal may cause the brakes to overheat, which reduces their effectiveness and may lead to more serious consequences.
o Take care of your tires. Keep them inflated to the recommended pressure. Incorrect infla- tion, either too much or too little, results in unnecessary tire wear. Check the tire pres- sures at least once a month.
o Be sure that the wheels are aligned correctly.
Improper alignment can result from hitting avoided by shifting at the recommendedspeeds.
o Use your air conditioning sparingly. The air
conditioning system is operated by engine power so your fuel economy is reduced when you use it.

DRIVING YOUR HYUNDAI
2- 12 The hitch should be bolted securely to the car and installed by a qualified technician. DO NOT USE A HITCH DESIGNED FOR TEMPORARY INSTALLATION AND NEVER USE ONE THAT ATTACHES ONLY TO THE BUMPER. C190C03S-GAT Trailer Brakes If your trailer is equipped with a braking system, make sure it conforms to federal and/or local regulations and that it is properly installed and operating correctly. NOTE: If you tow a trailer or vehicle, your car will require more frequent maintenance due to the additional load. See "Maintenance Under Severe Usage Conditions" on page 5-5. CAUTION:
o Never connect a trailer brake system di-
rectly to the vehicle brake system.
o When towing a trailer on steep grades (in excess of 12%) pay close attention to theengine coolant temperature gauge to en- sure the engine does not overheat. If the needle of the coolant temperature gauge moves across the dial towards "H" (HOT), pull over and stop as soon as it is safe to do so, and allow the engine to idle until it cools down. You may proceed once the engine has cooled sufficiently.
C180A01A-AAT USE OF LIGHTS Check your lights regularly for correct operation and always keep them clean. When driving dur- ing the day in conditions of poor visibility, it is helpful to drive with headlights on low beam. This enables you to be seen as well as to see. C190A02A-GAT TRAILER OR VEHICLE TOWINGIf you are considering towing with your car, you should first check with your Province Depart- ment of Motor Vehicles to determine their legal requirements. Since laws vary from province to province, the requirements for towing trailers, cars, other types of vehicles, or apparatus 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 properly break in. Failure to heed this caution may result in serious en- gine or transaxle damage. C190B01S-AAT Trailer Hitches Select the proper hitch and ball combination, making sure that it’s location is compatible with that of the trailer or vehicle being towed. Use a quality non-equalizing hitch which distrib- utes the tongue load uniformly throughout the chassis.
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 you may want to carry include tire chains, tow straps or chains, flashlight, emergency flares, sand, a shovel, jumper cables, 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 specifica- tion. Low tire inflation pressures will result in overheating and possible failure of the tires. Avoid using worn or damaged tires which may result in reduced traction or tire failure. NOTE: Never exceed the maximum tire inflation pres- sure shown on the tires. 2. Fuel, engine coolant and engine oil: High speed travel consumes 1.5 times more fuel than urban motoring. Do not forget to check both engine coolant and engine oil. 3. Drive belt: A loose or damaged drive belt may result in overheating of the engine.

WARNING: Improperly loading your car and trailer can serious affect its steering and braking perfor- mance causing a crash in which could cause serious injury or death.
Without Brake Type
5. Always secure items in the trailer to prevent load shift while driving.
6. Check the condition and air pressure of all
tires on the trailer and your car. Low tire pressure can seriously affect the handling. Also check the spare tire.
7. The vehicle/trailer combination is more af-
fected by crosswind and buffeting. When being passed by a large vehicle, keep a constant speed and steer straight ahead. If there is too much 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 follow all the normal precautions. Turn your 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 moving, and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time.
10. During your trip, check occasionally to be
sure that the load is secure, and that the lights and any trailer brakes are still working.
11. Avoid jerky starts, sudden acceleration 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 brakesto overheat, resulting in reduced braking effi- ciency. 14. When going down a hill, shift into a lower gear
and use the engine braking 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 in place by pressing on the accelerator. This can cause the automatic transaxle to overheat. Use the parking brake or footbrake.
NOTE: When towing check transaxle fluid more fre- quently. CAUTION: If overheating should occur when towing, (temperature gauge reads near red zone), taking the following action 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 selection in park or neutral and idle theengine at a higher speed.
C190F02A-GAT Trailer or Vehicle Towing Tips
1. Before towing, check hitch and safety chain
connections as well as proper operation of the trailer running lights, brake lights, and turn signals.
2. Always drive your vehicle at a moderate
speed (Less than 100 km/h).
3. Trailer towing requires more fuel than normal
conditions.
4. To maintain engine braking efficiency and
electrical charging performance, do not use fifth gear (manual transaxle) or overdrive (automatic transaxle).

When jump starting, wear protective glasses and be careful not to get acid on yourself, your clothing or on the car.
o If you should accidentally get acid on your
skin or in your eyes, immediately remove any contaminated clothing and flush the area with clear water for at least 15 minutes. Then promptly obtain medical attention. If you must be transported to an emergency facility, con- tinue to apply water to the affected area with a sponge or cloth.
o The gas produced by the battery during the
jump-start operation is highly explosive. Do not smoke or allow a spark or an open flame in the vicinity.
o The battery being used to provide the jump
start must be 12-volt. If you cannot determine that it is a 12-volt battery, do not attempt to use it for the jump start.
o To jump start a car with a discharged battery,
follow this procedure exactly:
1. If the booster battery is installed in another vehicle, be sure the two vehicles are nottouching.
2. Turn off all unnecessary lights and acces-
sories in both vehicles. 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. Then attach 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. Then attach the other end of that cable to a solid metal part of the engine away from the battery. Do not connect the cable to any moving part.
4. Start the engine in the car with the booster
battery and let it run for a few minutes. This will help to assure that the booster battery is fully charged. During the jumping operation, run the engine in this vehicle at about 2,000 rpm.
5. Start the engine in the car with the discharged
battery using the normal starting procedure. After the engine starts, leave the jumper cables connected and let the engine run at fast idle or about 2,000 rpm for several min- utes.
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 Hyundai dealer. D030A02A-AAT IF THE ENGINE OVERHEATS If your temperature gauge indicates overheating, you experience a loss of power, or hear loud pinging or knocking, 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" (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 under the car or steam is coming out from the hood, stop the engine. 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 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 satis- factory, 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).
