o Ensure that the overdrive switch is at the
"ON" position for maximum economy.
o If rapid acceleration is required, fully de- press the accelerator pedal. In this condi- tion, the kickdown mechanism will be oper-ated and the transaxle will automaticallydownshift according to the vehicle speed.
o Do not depress the accelerator pedal with the brakes applied and the selector at the"R" "D" "2" or "L" position.
o Turn the overdrive switch on for good fuel economy and smooth driving. But if enginebraking is needed in the "D" range or ifrepeated upshifting and downshifting be-tween the 3rd and 4th gear is needed whenclimbing a gentle slope, it is recommendedthat the overdrive switch be turned off. Turnthe overdrive switch back on immediatelyafterward.

EFFECTIVE BRAKING Braking system performance and friction mate-
rial life are greatly affected by the driving styleadopted. The following suggestions are madeto assist in achieving the best results from thebraking system.
o Anticipate the road and conditions ahead in order that heavy braking may be avoided.
o When descending long gradients, use the engine to assist in retarding the vehicle to minimize the possibility of brake fade occur-ring.
ZC120D1-E
General Operating Instructions
o The button in the selector handle must be depressed before the selector can be moved.
o The engine may only be started when the selector is at position "P" or "N".
o Ensure that the footbrake is firmly applied when shifting from "P" or "N" to "D", "2" or "L" and vice versa.
o Always engage the parking brake when the vehicle is unattended, never use the "P"position in place of the parking brake.
o Under normal circumstances, the selector should be placed in the "D" position and thetransaxle allowed to select the most idealratio for the circumstances. In this positionmaximum fuel economy will be achieved.
o When descending steep gradients where engine braking is required, the selectorshould be placed at the "2" or "L" positiondepending upon the vehicle speed.
o When ascending steep gradients and using large throttle openings, the transaxle mayrepeatedly change between two adjacentratios. This is a normal characteristic andmay be prevented by selecting "2" or "L"depending upon the vehicle speed.
o Never move the selector to or from the "P" or "N" position with the accelerator de-pressed. o When trailer towing, ensure that the trailer
brakes function correctly and use enginebrak-ing to assist the vehicle braking system.
o Use only genuine Hyundai replacement brake pads and shoes to ensure consistentfriction characteristics and wear rates.
o After driving through deep water (e.g. fording), the brakes may become wet andperformance reduced. Always check brakeefficiency after emerging from the water anddry the brakes by lightly depressing thebrake pedal several times whilst driving slow-ly.
o Apply the parking brake only when the vehi- cle is at rest.
o Since the power assistance provided by the brake servo is derived from the engine,coast-ing with the engine turned off or tow-ing of the vehicle with the engine turned offwill result in greatly increased pedal pres-sures being re-quired to stop the vehicle.
o Do not hold the vehicle on the upgrade with the accelerator pedal. This can cause thetransmission to overheat. Always use thebrake pedal or parking brake.

ANTI-LOCK BRAKE SYSTEM
(Not all models) The Anti-Lock Brake System (ABS) is designed
to prevent wheel lock-up during sudden braking or on hazardous road surfaces. The ABS con-trol module monitors the wheel speed and con-trols the pressure applied to each brake. Thus,

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.
SC150A1-F
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

Anti-freeze/Corrosion inhibitor The cooling system must always contain an
Ethylene-Glycol based anti-freeze solution. The system is filled during manufacture with solu-tion of the correct strength which should bechecked before the onset of winter and adjust-ed or changed as required.
NOTE: The anti-freeze solution contains a corro-
sion inhibitor to prevent degradation of the aluminum castings contained within theengine. Therefore, never, drain the systemand refill with water only.
In addition, anti-freeze solution must ALWAYS
be used in vehicles fitted with air conditioning,to prevent the heater matrix from freezing andsubsequently bursting with the refrigeration sys-tem in use. ZC170B1-E
Electrical System
Winter conditions impose severe demands upon
vehicle electrical systems, particularly the charg-ing circuit. The battery condition and perfor-mance along with the alternator performanceand drive belt condition should be checked priorto the onset of winter.
o Don’t "lug" or "over-rev" the engine. Lugging
is driving too slowly in too high a gearresulting in the engine bucking. If this hap-pens to you, shift to a lower gear. Over-revving is racing the engine beyond its safe limit. This can be avoided by shifting atthe recommended speeds.
o Use your air conditioning sparingly. The air conditioning system is operated by the en-gine power so your fuel economy is reducedwhen you use it.
SC160A1-F
SMOOTH CORNERING Avoid braking or gear changing in corners,
especially when roads are wet. Ideally, cornersshould always be taken under gentle accelera-tion. If you follow these suggestions, tire wearwill be held to a minimum.
SC170A1-E
WINTER MOTORING The onset of winter conditions subject motor
vehicles to greater operating demands. There-fore, the following suggestions will assist inmaintaining peak performance and reliabilityduring these periods: ZC170D1-E
Door Locks
Should the door lock mechanism become fro-
zen, a proprietary lock de-icer should be used.Alternatively, warming the door key may thawthe door lock. However, the key should behandled carefully to avoid burning the fingers.
Never attempt to thaw a frozen door lock using
hot water, since the water will eventually freezeand compound the problem.
NOTE:The proper temperature for using the immo-
bilizer key is from -40°F to 176°F(from -40°Cto 80°C). If you heat the immobilizer keyover 176°F(80°C) to open the frozen lock, itmay cause damage to the transponder in itshead.
ZC170E1-E
Windscreen Washers & Wipers The windscreen washer bottle should be filled
with a solution of water and a proprietary winterscreen wash additive. The windscreen wipersshould not be used it the blades are frozen tothe windscreen or if they are covered withsnow, before this is removed.
NOTE: Never allow undiluted screen washer fluid
additive to spill upon the paintwork or use engine coolant anti-freeze since damage tothe paintwork may result.

DRIVING YOUR HYUNDAI
2- 10 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 the engine coolant temperature gauge to
ensure the engine does not overheat. Ifthe needle of the coolant temperaturegauge moves across the dial towards"H" (HOT), pull over and stop as soon as
it is safe to do so, and allow the engine toidle until it cools down. You may proceed
once the engine has cooled sufficiently.
C190D01A-GAT
Safety Chains Should the hitch connection between your carand the trailer or vehicle you are towing fail, thetrailer or vehicle could wander dangerouslyacross other lanes of traffic and ultimately col-lide with another vehicle. To eliminate this po-tentially dangerous situation, safety chains, attached between your car and the trailer ortowed vehicle, are required in most provinces.
o When driving in extreme conditions, the
windscreen wiper blades may fail to clearthe screen properly due to the formation ofice upon the blade edge. It will therefore benecessary to periodically remove such iceto restore their efficiency.
o If the power operated door mirrors become frozen, attempts to adjust these may dam-age the mechanism.
o The formation of snow or ice build up inside the wheel arches may interfere with theroadwheels or steering mechanism. In suchinstances, unusual noises or an increase insteering effort may result. Therefore, ensurethat the wheelarches are checked periodi-cally and any accumulated snow or iceremoved.
o It is advisable to carry emergency equip- ment including, torch, shovel, tow rope, blan-kets etc., if a journey is to be undertaken intoareas of severe road conditions. CAUTION: Do not do any towing with your car during
its first 1,200 miles in order to allow the engine to properly break in. Failure to heedthis caution may result in serious engine ortransaxle damage.
C190B01S-AAT
Trailer Hitches Select the proper hitch and ball combination,
making sure that it's location is compatible withthat of the trailer or vehicle being towed. Use aquality non-equalizing hitch which distributesthe tongue load uniformly throughout the chas-sis.
The hitch should be bolted securely to the car
and installed by a qualified technician. DO NOTUSE A HITCH DESIGNED FOR TEMPORARY
INSTALLATION AND NEVER USE ONE THATATTACHES ONLY TO THE BUMPER.
C190A01A-EAT
TRAILER OR VEHICLE TOWING
If you are considering towing with your car, you
should first check with your Province Depart-ment of Motor Vehicles to determine their legalrequirements.
Since laws vary from province to province the
requirements for towing trailers, cars, or othertypes of vehicles or apparatus may differ. Askyour Hyundai dealer for further details beforetowing. C190C01X-GAT
Trailer Brakes If your trailer is equipped with a braking system,
make sure it conforms to federal and/or localregulations and that it is properly installed andoperating correctly. NOTE: If you tow a trailer or vehicle, your car will require more frequent maintenance due tothe additional load. See Maintenance UnderSevere Usage Conditions" on page 5-4.

2- 12 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 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

IF THE ENGINE WILL NOT START Seek assistance from the nearest Hyundai
dealer with regard to the method of ignition andfuel system diagnosis.
CAUTION: If the engine refuses to start, no attempt
should be made to push or tow start the vehicle. Vehicles with automatic transaxleor fuel injection will not be able to be startedin this manner since no drive is transmittedthrough the automatic transaxle whilst theengine is not running, and in the case of fuelinjected derivatives, the fuel pump will notoperate under tow start conditions. In addi-tion, if the vehicle is equipped with an ex-haust catalyst, damage to the catalyst mayresult if the vehicle is tow started. ZD000A1-E

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.
