About the Catalytic Converter
Exhaust gases passing through the catalytic
converter cause it to operate at very high tem- peratures. As a result, the introduction of largeamounts of unburned gasoline may cause it tooverheat and create a fire hazard. This can beavoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good condition. Ex- tremely high converter temperatures can result from improper operation of the electri-cal, ignition or fuel injection systems.
o If your engine stalls, pings, knocks, or is hard to start, take your car to your Hyundaidealer as soon as possible and have thedifficulty corrected.
o Avoid driving with a very low fuel level. If your run out of gasoline, it could cause theengine to misfire and result in excessiveloading of the catalytic converter.
o Avoid idling the engine for periods longer than 10 minutes.
o Your Hyundai should not be either pushed or pulled to get it started. This can cause thecatalytic converter to overload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper,leaves or rags. As these materials couldcome in contact with the catalytic converterand could cause a fire. o Do not touch the catalytic converter or any
other part of the exhaust system while theengine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai dealer is your best source of assistance.

SB210P1-E
LOW FUEL LEVEL WARNING LAMP
The low fuel warning lamp serves to warn the driver that the remaining fuel quantity is approxi-mately 9 litres and that the vehicle should berefuelled. If the vehicle is driven for an extendedperiod with the low fuel warning lamp illuminatedthere exists a possibility that misfiring due to fuel
becoming defective, approximately fifty per centof the normal braking performance will be avail-able.If failure of one of the circuits occurs, the requiredamount of pedal effort, pedal travel and stoppingdistance will be increased. Use of the gearbox isrecommended to assist in bringing the vehicle torest. The vehicle must not be driven once brakefailure has occurred until the system has beenrepaired and is functioning normally.The braking system employs a vacuum servo inorder that the pedal efforts are reduced. Powerfor the servo is derived from the engine andtherefore, in the event of the engine stopping orthe vehicle being towed, pedal efforts will besubstantially increased. SB210M1-E
CHARGING SYSTEM WARNING LAMP
The charging system warning lamp should illumi- nate when the ignition switch is turned to the"ON" position and should be extinguished whenthe engine is started. If the lamp fails to illuminatewhen the ignition is turned "ON" or fails to extin-guish after starting the engine, the nearestHyundai dealer should be contacted. If the lampilluminates whilst the vehicle is being driven, stopthe vehicle as soon as it is safe to do so andcheck the condition of the generator drive belt. Ifthe belt is in place and the tension is satisfactory,the advice of a Hyundai dealer should be sought.
B260H01GK-EAT PARKING BRAKE/BRAKE FLUID LEVEL WARNING LAMP
CAUTION: In the event of problems being suspected with the braking system, the advice of thenearest Hyundai dealer must be sought be-fore the vehicle is driven. Driving the vehiclewith either an electrical or hydraulic brakingsystem defect may be dangerous, resultingin accident or personal injury. Warning lamp operation The parking brake/brake fluid level warning lamp will be illuminated whenever the ignition switch isturned to the "ON" or "START" position when theparking brake is applied and must be extin-guished in a three seconds after the enginestarts.If the warning lamp fails to extinguish or illumi-nates at any other time, the vehicle must bebrought to rest in a safe location and the level ofbrake fluid in the reservoir checked. If the fluidlevel is incorrect, fluid conforming to DOT 3 orDOT 4 specifications should be added. If, aftercorrecting the brake fluid level, the warning lampcontinues to be illuminated, the advice of thenearest Hyundai dealer must be sought beforethe vehicle is driven again.The Hyundai Coupe is equipped with a diago-nally split dual braking system which will ensurethat in the event of one of the brake circuits SB210N2-E

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.

DRIVING YOUR HYUNDAI
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,

DRIVING YOUR HYUNDAI 2- 9
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, coasting with the engine turned off or towingof the vehicle with the engine turned off willresult in greatly increased pedal pressuresbeing required to stop the vehicle.
o Do not hold the vehicle on the upgrade with the accelerator pedal. This can cause thetransaxle to overheat. Always use the brakepedal or parking brake.
SC140B1-E
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,in emergency situations or on slick roads, ABSwill increase vehicle control during braking.
NOTE: During ABS operation, a slight pulsation
may be felt in the brake pedal when the brakes 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: ABS will not prevent accidents due to im-
proper or dangerous driving manoeuvres. 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 with
an anti-lock braking system may be longerthan for those without it in the followingroad conditions.
o Rough, gravel or snow-covered roads.
o With tire chains installed.
o On roads where the road surface is pit- ted or has different surface height.
These roads should be driven at reduced
speeds. The safety features of an ABS equipped vehicle should not be tested byhigh speed driving or cornering. This couldendanger the safety of yourself or others. C300A03Y-EAT
TRACTION CONTROL SYSTEM (TCS) (Not all models)
HGK156A-D
On slippery road surfaces, the traction control system (TCS) limits the drive wheels from spin-ning excessively, thus helping the car to accel-erate. It also provides sufficient driving forceand steering performance as the car turns ataccelerated speeds.
SLIP Control Limits the drive wheels from spinning exces-sively during starting or while making accelerat-ed turns on slippery roads to avoid losing thedriving force of the front wheels.
Driving hints TCS does not actively apply brakes. Be sure todecelerate the car sufficiently before enteringcurves.

9. If the trailer has electric brakes, start your
vehicle and trailer moving, and then apply the trailer brake controller by hand to besure the brakes are working. This lets youcheck 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 the transaxle to a lower gear and reduce speedto reduce chances of engine overloadingand/or overheating.
15. If you have to stop while going uphill, do not hold the vehicle in place by pressing on theaccelerator. 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 the engine at a higher speed.

IN CASE OF EMERGENCY
3-2 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 satisfac-tory, check for coolant leaking from the radia-tor, hoses or under the car. (If the air condi-tioning had been in use, it is normal for coldwater to be draining from it).
WARNING:Whilst the engine is running, keep hands andclothing away from moving parts such as thefan 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.
6. If the cause of the overheating cannot be found, wait until the engine temperature has returned to normal. Then, if coolant has beenlost, carefully remove the radiator cap andadd water to bring the fluid level in the reser-voir up to the base of the radiator fill opening.Fill the coolant expansion tank to the halfwaymark.
WARNING:Motor vehicle batteries contain sulphuric acidand emit hydrogen gas. Protective clothingshould be worn and care exercised to preventthe acid from coming into contact with skin orclothing and the vehicle. Naked lights shouldnot be permitted in the vicinity of the battery.Care should be exercised to prevent sparksoccurring during connection. If acid acciden-tally comes into contact with skin or eyes, theaffected area should immediately be flushedwith copious amounts of water and medicalassistance sought.
1. Ensure that the booster battery is 12 volt type.
If the booster battery is installed in another vehicle, ensure that the two vehicles are nottouching.
2. Turn off all unnecessary electrical equipment 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 the otherend to the positive (+) terminal of the dis-charged 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 the vehi-cle with the flat battery.
7. Remove jump cables in the reverse order of installation (black cable first).
CAUTION:If the jump cable is incorrectly installed, dam-age to the vehicle electrical system may oc-cur, in particular the electronic componentssuch as the Fuel Injection system computerand the Automatic Transaxle computer. Thebattery must never be disconnected whilstthe engine is running. SD040A1-E IF THE ENGINE OVERHEATSIf 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) and set the parking brake. If the air conditioning is on,turn it off.
3. If coolant is running out under the car or steam is coming out from under the bonnetstop the engine. Do not open the bonnet untilthe coolant has stopped running or the steam-ing has stopped. If there is no visible loss ofcoolant and no steam, leave the engine run-ning and check to be sure the engine coolingfan is operating.If the fan is not running, turn the engine off.

IN CASE OF EMERGENCY
SD060A1-E IN THE EVENT OF A PUNCTUREIf a puncture occurs whilst driving the vehicle:
1. Bring the car to rest as soon as it is safe to do so and with the minimum amount of braking required which will assist in main-taining the maximum amount of control. Thevehicle should be parked wherever possibleupon firm level ground to facilitate wheelchanging.
2. If the vehicle is creating a hazard and the road conditions do not permit the wheel to bechanged safely, assistance should be sought.
3. Passengers must not be allowed to remain inside the vehicle during wheel changing. Ifa puncture occurs whilst the vehicle is on a SD070A1-E CHANGING A FLAT TYRE
7. Proceed with caution until it is established
that the engine is operating normally. If the engine overheats repeatedly, the advice of aHyundai dealer should be sought.
CAUTION:Serious loss of coolant indicates there is aleak in the cooling system and this should bechecked as soon as possible by a Hyundaidealer.
It is of the utmost importance that care is exer-cised when changing road wheels. Ensure thatthe parking brake is set and that the gear shiftlever is in reverse (P, if the vehicle has automatictransaxle).
D040A01GK-EAT TEMPORARY SPARE TYREThe following instructions for the temporary spare tyre should be observed:
1. Check inflation pressure as soon as practical
after installing the spare tyre, and adjust to the specified pressure. The tyre pressure shouldbe periodically checked and maintained atthe specified pressure while the tyre is stored.
2. The spare tyre should only be used temporari-
ly and should be returned to the luggagecompartment as soon as the original tyre canbe repaired or replaced.
3. Continuous use at speeds of over 50 mph (80 km/h) is not recommended. 4. As the temporary spare tyre is specifically
designed for your car, it should not be used onany other vehicle.
5. The temporary spare tyre should not be used on any other wheels, nor should standardtyre, snow tyre, wheel covers or trim rings beused with the temporary spare wheel. If suchuse is attempted, damage to these items orother car components may occur.
6. The temporary spare tyre pressure should be checked once a month while the tyre is stored.

SG050A1-E ENGINE COOLANT CHECKING AND REPLACING WARNING: Do not remove the radiator cap when the engine is hot, since the system is pressurizedand coolant may be ejected from the radiatorresulting in scalding. SG050B1-E Coolant recommendations
Only ethylene glycol based coolant with a corro- sion inhibitor suited to aluminium alloy enginecomponents should be used in the cooling sys-tem. No further additives or inhibitors should beused. The coolant specific gravity should bechecked as prescribed in the maintenance sched-ule to ensure adequate frost and corrosion pro-tection. In addition, the engine coolant must bereplaced at the specified interval since the corro-sion inhibitor properties deteriorate with time.It is important to note that whilst an increase in theconcentration of anti freeze gives an increase inthe level of frost protection, a solution which is inexcess of 65% anti freeze will result in reducedfrost protection and engine overheating. There-fore the recommended concentration of 50%should not be exceeded for general use.The use of methanol based anti freeze com-pounds may result in engine overheating and willinvalidate the vehicle warranty. NOTE: It is imperative that vehicles fitted with an airconditioning system have a coolant concen-tration of the recommended strength at alltimes. The use of the air conditioning systemwhen the cooling system is filled with wateronly will result in the heater matrix freezingand subsequently bursting.SG050C1-E Engine Coolant LevelThe engine coolant level may be observed through the side of the plastic coolant reservoir(expansion tank) when the engine is cold. If thelevel is below the "LOW" mark, add coolant of thecorrect concentration until the level is betweenthe "LOW" and "Full" marks. If the level fallsbelow the "LOW" mark on a regular basis despitebeing topped up, consult a Hyundai dealer. SG050D1-E To Change the Engine CoolantThe engine coolant should be changed at those intervals specified in the vehicle maintenanceschedule in Section 5. NOTE: Care should be taken to ensure that coolantis not allowed to spill onto the paintworksince the finish may become damaged. Ifcoolant spillage occurs, the affected areashould be rinsed thoroughly with water.
1. Park the vehicle on level ground and ensure
that the parking brake is firmly applied, and the engine allowed to cool.DO NOT ATTEMPT THIS OPERATIONWHILST THE ENGINE IS HOT SINCEBURN-ING OR SCALDING MAY RESULT.
2. Prepare a suitable receptacle to collect the displaced coolant and position this under theradiator drain tap.
