DRIVING YOUR HYUNDAI
2- 8 in emergency situations or on slick roads, ABS will increase vehicle control during braking. NOTE: During ABS operation, a slight pulsation may be felt in the brake pedal when thebrakes are applied. Also, a noise may beheard in the engine compartment while brak-ing. These conditions are normal and indi-cate that the anti-lock brake system is func-tioning properly. WARNING: Your ABS will not prevent accidents due to improper or dangerous driving maneuvers.Even though vehicle control is improvedduring emergency braking, always maintaina safe distance between you and objectsahead. Vehicle speeds should always bereduced during extreme road conditions.The braking distance for cars equipped withan anti-lock braking system may be longerthan for those without it in the followingroad conditions.
o Driving on rough, gravel or snow-cov- ered roads.
o Driving with tire chains installed.
o Driving on roads where the road surface is pitted or has different surface height.
These roads should be driven at reduced speeds. The safety features of an ABSequipped vehicle should not be tested by high speed driving or cornering. This couldendanger the safety of yourself or others.
unnecessary tire wear. Check the tire pres-sures at least once a month.
o Be sure that the wheels are aligned cor- rectly. Improper alignment can result fromhitting curbs or driving too fast over irregularsurfaces. Poor alignment causes faster tirewear and may also result in other problemsas well as greater fuel consumption.
o Keep your car in good condition. For better fuel economy and reduced maintenancecosts, maintain your car in accordance withthe maintenance schedule in Section 5. Ifyou drive your car in severe conditions,more frequent maintenance is required (seeSection 5 for details).
o Keep your car clean. For maximum service, your car should be kept clean and free ofcorrosive materials. It is especially impor-tant that mud, dirt, ice, etc. not be allowed toaccumulate on the underside of the car. Thisextra weight can result in increased fuelconsumption and also contribute to corro-sion.
o Travel lightly. Don’t carry unnecessary weight in your car. Weight is an enemy of good fueleconomy.
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 whenyou’re ready to go.
o Remember, your car does not require ex- tended warm-up. As soon as the engine isrunning smoothly, you can drive away. Invery cold weather, however, give your en-gine a slightly longer warm-up period.

DRIVING FOR ECONOMY You can save fuel and get more miles from yourcar 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 cruisingspeed. Don’t race between stoplights. Try toadjust your speed to that of the other trafficso you don’t have to change speeds unnec-essarily. Avoid heavy traffic whenever possible. Al- ways maintain a safe distance from othervehicles 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 ata moderate speed, especially on the high-way, is one of the most effective ways toreduce fuel consumption.
o Don’t "ride" the brake or clutch pedal. This can increase fuel consumption and alsoincrease wear on these components. In ad-dition, driving with your foot resting on thebrake pedal may cause the brakes to over-heat, which reduces their effectiveness andmay 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

hold the vehicle in place by pressing on the accelerator. This can cause the automatictransaxle to overheat. Use the parking brakeor footbrake.
NOTE: When towing, check transaxle fluid more frequently. CAUTION: If overheating should occur when towing,
(temperature gauge reads near red zone),taking the following action may reduce oreliminate 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.
being passed by a large vehicle, keep aconstant speed and steer straight ahead. If there is too much wind buffeting, slow
down to get out of the other vehicle's airturbulence.
8. When parking your car and trailer, especial- ly on a hill, be sure to follow all the normalprecautions. Turn your front wheel into thecurb, set the parking brake firmly, and putthe transaxle in 1st or Reverse (manual) orPark (automatic). In addition, place wheelchocks at each of the trailer's tyres.
9. If the trailer has electric brakes, start your vehicle and trailer moving, and then applythe trailer brake controller by hand to be
sure the brakes are working. This lets you
check your electrical connection at the sametime.
10. During your trip, check occasionally to be sure that the load is secure, and that thelights 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 brakes to overheat, resulting in reduced brakingefficiency.
14. When going down a hill, shift into a lower gear and use the engine braking effect.When ascending a long grade, downshift thetransaxle to a lower gear and reduce speedto reduce chances of engine overloading
and or overheating.
WARNING:
o The tongue load should never exceed;
Auto Transaxle : 55.1 lb Manual Transaxle 9: 61.7 lb
o Maximun permissible mass of the cou- pling device (ATOS VAN only) : 44 lb
o Improperly loading your car and trailer can serious affect its steering and brak- ing performance causing a crash in which
you may be seriously injured or killed.

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, andturn signals.
2. Always drive your vehicle at a moderate speed (Less than 62 MPH).
3. Trailer towing requires more fuel than nor- mal conditions.
4. To maintain engine braking efficiency and electrical charging performance, do not usefifth gear (manual transaxle) or overdrive(automatic transaxle).
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 tyrepressure can seriously affect the handling.Also check the spare tyre.
7. The vehicle/trailer combination is more af- fected by crosswind and buffeting. When

WHAT TO DO IN AN EMERGENCY
3-2 3. If coolant is running out under the car or
steam is coming out from under the bonnet stop the engine. Do not open the bonnetuntil the coolant has stopped running or thesteaming has stopped. If there is no visibleloss of coolant and no steam, leave theengine running and check to be sure theengine cooling fan is operating. If the fan isnot 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 thatit is tight. If the drive belt seems to besatisfactory, check for coolant leaking fromthe radiator, hoses or under the car. (If theair conditioner had been in use, it is normalfor cold water to be draining from it).
WARNING: While the engine is running, keep hands andclothing away from moving parts such asthe fan and drive belts to prevent injury.
5. If the water pump drive belt is broken or coolant is leaking out, stop the engine imme-diately and call the nearest Hyundai dealerfor assistance.
WARNING: Do not remove the radiator cap when theengine is hot since steam and boiling watermay be ejected from the radiator resulting inburns or scalding.
CAUTION:
Personal injury and damage to the vehicle
may occur if jump starting is not performedcorrectly. If any doubt exists as to how thisoperation should be performed, seek assis-tance from qualified personnel. WARNING:
Motor vehicle batteries contain sulphuric
acid and emit hydrogen gas. Protective cloth- ing should be worn and care exercised toprevent the acid from coming into contactwith skin or clothing and the vehicle. Nakedlights should not be permitted in the vicinityof the battery. Care should be exercised topreventsparks occurring during connection.If acid accidentally comes into contact withskin or eyes, the affected area should imme-diately be flushed with copious amounts ofwater and medical assistance sought.
1. Ensure that the booster battery is 12 volt type. If the booster battery is installed in another vehicle, ensure that the two vehi-cles are not touching.
2. Turn off all unnecessary electrical equip- ment in both vehicles.
3. Ensure that the engine of the vehicle provid- ing the jump start is running prior to connec-tion of the jump cables.
4. Connect the red jump cable to the positive (+) terminal of the booster battery and theother end to the positive (+) terminal of thedischarged battery. 5. Attach the black jump cable to the negative
(-) terminal of the booster battery, and theother end to a ground point within the enginecompartment of the vehicle with the flat bat-tery. Do not connect to the negative batteryterminal of the flat battery since sparks maybe generated with the subsequent risk ofexplosion.
6. Raise the booster vehicle engine speed to 2,000 r.p.m. and start the engine of thevehicle with the flat battery.
7. Remove jump cables in the reverse order of installation (black cable first).
NOTE: If the jump cable is incorrectly installed, damage to the vehicle electrical system mayoccur, in particular the electronic compo-nents such as the Fuel Injection systemcomputer and the Automatic Transaxle com-puter. The battery must never be discon-nected whilst the engine is running. XD040A1-E
IF THE ENGINE OVERHEATS If the temperature gauge indicates overheating:
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, semi- automatic transalxe) and set the parkingbrake. If the air conditioner is on, turn it off.
