The radiator cap mustonly be removed when the engine has cooled.Do not add cold water to a hot engine to avoidthe possibility of engine damage. The use ofplain water in the cooling system is not rec-ommended since the aluminium componentsof the cooling system require the use of acorrosion inhibitor found in the recommendedEthylene Glycol type anti freeze solutions.
The engine coolant temperature gauge indicatesthe engine coolant temperature and will, undernormal circumstances, give an indication in the"Normal" or centre portion of the scale. Shouldthe indication move into the upper or "Hot" por-tion of the scale, engine overheating is indicated.Under these circumstances, the vehicle shouldbe brought to rest as soon as is safe to do so andthe engine turned off. Once the engine has cooledsomewhat, the coolant level and the condition ofthe generator/water pump drive belt should bechecked. If the cause of the overheating cannotbe readily established, the assistance of aHyundai dealer should be sought.

B740D01A-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 conditioning sys- tem, keep all windows closed to keep hot airout.
o When moving slowly, as in heavy traffic, shift to a lower gear. This increases engine speed,which in turn increases the speed of the airconditioning compressor.
o On steep grades, turn the air conditioner off to avoid the possibility of the engine over-heating.
o During winter months or in periods when the air conditioner is not used regularly, run theair conditioner once every month for a fewminutes. This will help circulate the lubricantsand keep your system in peak operatingcondition.

2- 4 SC060B1-E FUEL ECONOMY
The following suggestions are made to assist in
achieving the greatest degree of fuel economy.
o Maintaining a constant check on fuel con- sumption will enable the most economical use pattern and driving style to be adopted.
o Avoid using the vehicle for very short jour- neys if possible, particularly when a coldstart is involved.
o Ensure that tyre pressures are maintained at the correct level.
o Use only the recommended grade of fuel.
o Avoid carrying unnecessary weight, and if a roof rack is in use, remove it as soon as possible after use.
o Anticipate the road and conditions ahead to enable adjustments in speed to be madesmoothly. Avoid heavy acceleration and sharpbraking.
o Avoid cruising at unnecessary high speeds.
o Always ensure that the periodic maintenance services are performed by a Hyundai dealer
at the time and/or mileage intervals speci-fied.
o Use the air conditioning only when neces- sary.
NOTE: Do not operate the starter for more than 15
seconds continuously or continue to oper- ate the starter after the engine has started toavoid damaging the starter motor. If theengine makes a false start, allow it and thestarter motor to come to rest before at-tempting to start the engine again. Neverattempt to start the engine with the transaxlein gear. Do not depress the accelerator pedalwhilst starting the engine. Allow the engineto idle for 20 seconds or so before drivingthe vehicle.
CAUTION: Do not leave the vehicle unattended whilst
idling. Never allow the vehicle to idle or warm up in a confined space (ie garage)longer than is necessary to move the vehi-cle into an open area. C070A01GK-EAT MANUAL TRANSAXLE The five speed fully synchronized transaxle is controlled by a floor mounted shift lever uponwhich the shift pattern is indicated.

2- 8 when you are driving down a long hill, slow down and shift to a lower gear. When you dothis, engine braking will help slow the car.
o Slow down before shifting to a lower gear. Otherwise, the lower gear may not be en-gaged.
o Always use the parking brake. Do not de- pend on placing the transaxle in "P" to keepthe car from moving.
o Exercise extreme caution when driving on a slippery surface. Be especially careful whenbraking, accelerating or shifting gears. On aslippery surface, an abrupt change in vehi-cle speed can cause the drive wheels tolose traction and the vehicle to go out ofcontrol.
WARNING:
o Avoid high cornering speeds.
o Do not make quick steering wheel move- ments, such as sharp lane changes or fast, sharp turns.
o Always wear your seat belts. In a collision crash, un unbelted personis significantly more likely to die than aperson wearing a seatbelt.
o The risk of rollover is greatly increased if you lose control of your vehicle at high-way speeds.
o Loss of control often occurs if two or more wheels drop off the roadway andthe driver oversteers to reenter the road-way. o In the event your vehicle leaves the road-
way, do not steer sharply. Instead, slowdown before pulling back into the travellanes.
o Never exceed posted speed limits. SC140A1-E EFFECTIVE BRAKING Braking system performance and friction mate- rial life are greatly affected by the driving styleadopted. The following suggestions are made toassist 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.
o When trailer towing, ensure that the trailer brakes function correctly and use enginebraking 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.
C090I01L-GAT
CAUTION:
o Shift into "R" and "P" position only when the vehicle has completely stopped.
o Do not accelerate the engine in reverse or any of the forward positions with the brakes applied.
o Always apply the footbrake when shift- ing from "P" or "N", to "R", "D"position.
o Do not use the "P" (Park) position in place of the parking brake. Always setthe parking brake, shift the transaxle into"P" (Park) position and turn off the igni-tion when you leave the vehicle, evenmomentarily. Never leave the vehicleunattended while the engine is running.
o Check the automatic transaxle fluid level regularly, and add fluid as necessary.
C090N02O-AAT
Good Driving Practices
o Never move the gear selector lever from "P" or "N" to any other position with the acceler- ator pedal depressed.
o Never move the gear selector lever into "P" when the vehicle is in motion.
o Be sure the car is completely stopped be- fore you attempt to shift into "R".
o Never take the car out of gear and coast down a hill. This may be extremely hazard-ous. Always leave the car in gear whenmoving.
o Do not "ride" the brakes. This can cause them to overheat and malfunction. Instead,

Indicators and Warning The indicators should illuminate when the igni-
tion key is turned to ON or START but should go out after three seconds.
If the indicators do not illuminate, or the TCS or
TCS-OFF indicator does not go out after 3seconds, have it checked by an authorizeddealer.
Should there be any unusual conditions in the
device while driving, TCS-OFF indicator illumi-nates as a warning.
If TCS-OFF indicator illuminates, pull your car
to a safe place and stop the engine. Then, start the engine again to check if the
TCS-OFF indicator goes out.
If the indicator remains lit even after the engine
has been started, have your car checked by anauthorized Hyundai dealer. effect of brake control and indicates noth-ing unusual.
3) When the engine starts, a click is heard from the engine compartment; however,this is only the sound of traction controlbeing checked.
4) When moving out of the mud or fresh snow, pressing the accelerator pedal maynot cause the engine speed to increasedue to TCS operation. NOTE:
1) When the TCS-OFF indicator illuminates,
traction control is automatically deacti- vated for safety.
2) This warning function is not provided when the driver selects the TCS-OFFmode.
SC150A1-F DRIVING FOR ECONOMY You can save fuel and get more miles 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 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-

TCS ON/OFF Mode When the TCS is running, the TCS indicator
light in the instrument cluster will blink. If you turn the system off by pressing the TCS
switch, the TCS-OFF indicator light will comeon and stay on. In the TCS-OFF mode, theSLIP control will be deactivated. Adjust youdriving accordingly. To turn the system backon, press the switch again. The TCS-OFF indi-cator light should go off.
NOTE:
1) The TCS mode will automatically be turned ON after the engine is turned offand restarted.
2) When the traction control system is op- erating properly, you can feel a slightpulsation in the vehicle. This is only the

heat, 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 inunnecessary 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.
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: ZC170B1-E
Electrical System
Winter conditions impose severe demands uponvehicle 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. ZC170C1-E
Anti-freeze/Corrosion inhibitor The cooling system must always contain an Ethylene-Glycol based anti-freeze solution. Thesystem 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 thealuminum 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.

o When driving in extreme conditions, the
windscreen wiper blades may fail to clear the 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 built up inside the wheel arches may interfere with the roadwheels or steering mechanism. In such in-stances, unusual noises or an increase insteering effort may result. Therefore, ensurethat the wheel arches 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.

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 (-40°C) to 176°F(80°C). If you heat the immobilizer key over176°F (80°C) to open the frozen lock, it maycause damage to the transponder in its head. SC170E1-E Windscreen Washers and Wipers
The windscreen washer bottle should be filled
with a solution of water and a proprietary winter screen wash additive. The windscreen wipersshould not be used if 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.

TOWING ATTACHMENTS
It is strongly recommended that only an Hyundai
Approved towing attachment is used to ensure that the loads placed upon the body structureare correctly distributed. The use of a nonapproved attachment will result in the invalida-tion of the vehicle warranty. Hyundai towingattachments are designed and constructed toensure maximum towing performance and easeof fitment. A range of accessories includingelectrical kits and mirrors are available throughthe Hyundai dealer network.
It is of the utmost importance that those areas
of the vehicle which are subjected to greaterstress during towing are maintained in accor-dance with the recommendations given at theend of this book. In addition, the daily operatingchecks relating to engine oil, transaxle oil andtyres must be performed at each refuelling toensure maximum reliability and safety.
The use of a proprietary stabiliser will assist in
achieving an inherently stable outfit but whilstthe use of such equipment will improve thecharacteristics of a balanced outfit, it will notcompensate for a badly loaded and thereforeunstable outfit.
The tyres and braking equipment fitted to the
trailer or caravan must be maintained in accor-dance with the recommendations of the manu-facturer. Special attention should be paid totyres which deteriorate through time and expo- sure rather than as a result of the distancestowed. The inside walls of the tyres should beinspected along with the outside walls for crack-ing and damage. The trailer wheel nut torquemust be checked on a regular basis, preferablybefore each towing session.
The trailer towbar hitch and the safety catch
mechanism must be maintained in good work-ing order. The trailer break away cable or cableshould be inspected for damage and should beattached to the vehicle towing attachment eachand every time the trailer is hitched to thevehicle.
Whilst towing, the performance of the vehicle
will be reduced in terms of acceleration, brakingand handling due to the increased loads placedupon the vehicle. The driver should anticipatethe change in characteristics and adjust thedriving style in keeping with these changes.Care should be exercised when cornering andbraking to prevent the outfit becoming uncon-trollable by reducing cornering speeds and al-lowing increased braking distances.
The driver should exercise care to ensure that
when pulling away from rest particularly onuphill gradients the clutch unit is not subjectedto excessive slippage which will reduce theuseful life of this component. Use of the "Over-drive Off" "2" and "L" positions when drivingvehicles with automatic transaxle will assistwith braking performance when long down hill gradients are encountered. Improved accelera-tion performance will be available by selecting"Overdrive Off","2", or "1" depending upon roadspeed if it is found that the transaxle unit makesan undesirable upshift whilst hill climbing orovertaking. The transaxle unit should be oper-ated in "D" with the Overdrive "On" undernormal circumstances to enhance fuel economyand reduce noise and engine wear.

1. Before towing, check towbar hitch and safe-
ty cable connections as well as proper oper- ation of the trailer running lights, brake lights,and turn signals.
2. Always drive your vehicle at a moderate speed (Less than 60mph).
3. Trailer towing requires more fuel than nor- mal conditions.
4. To maintain engine braking efficiency, do not tow a trailer with the transaxle engagedin an overdrive gear.
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 tirepressure 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, slowdown 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 tires.
