tance. Automobile batteries contain sulfuric acid. This is poisonous and highly corrosive.When jump starting, wear protective glassesand 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 withclear water for at least 15 minutes. Thenpromptly obtain medical attention. If you mustbe transported to an emergency facility, con-tinue to apply water to the affected area witha sponge or cloth.
o The gas produced by the battery during the jump-start operation is highly explosive. Donot smoke or allow a spark or open flame inthe vicinity.
o The battery being used to provide the jump start must be 12-volt. If you cannot determinethat it is a 12-volt battery, do not attempt touse 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 on the previous page.First, attach one clamp of the jumper cable tothe positive (+) post or cable of the dis-charged battery. Then attach the other end ofthe same cable to the positive (+) post orcable of the booster battery. Next, using theother cable, attach one clamp to the negative(-) post or cable of the booster battery. Thenattach the other end of that cable to a solidmetal part of the engine away from thebattery. Do not connect the cable to anymoving part.
4. Start the engine in the car with the booster battery and let it run for a few minutes. Thiswill help to assure that the booster battery isfully charged. During the jumping operation,run the engine in this vehicle at about 2000rpm.
5. Start the engine in the car with the discharged battery using the normal starting procedure.After the engine starts, leave the jumpercables connected and let the engine run atfast idle or about 2000 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 becamedischarged (because the lights were left on,etc.), have the charging system checked by yourHyundai dealer. D030A02A-AAT IF THE ENGINE OVERHEATSIf your temperature gauge indicates overheating, you experience a loss of power, or hear loudpinging or knocking, the engine is probably toohot. 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, stopthe engine. Do not open the hood until theengine coolant has stopped running or thesteaming has stopped. If there is no visibleloss of engine coolant and no steam, leavethe engine 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 be satis-factory, check for engine coolant leaking fromthe radiator, hoses or under the car. (If the airconditioning had been in use, it is normal forcold water to be draining from it when youstop).
WARNING:While the engine is running, keep hair, hands,and clothing away from moving parts such asthe fan and drive belts to prevent injury.

WHAT TO DO IN AN EMERGENCY 3-3
5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the engine immediately and call the nearest Hyundaidealer for assistance.
WARNING:Do not remove the radiator cap when theengine is hot. This can allow coolant to beblown out of the opening and cause seriousburns.
6. If you cannot find the cause of the overheat- ing, wait until the engine temperature has returned to normal. Then, if the engine cool-ant has been lost, carefully add coolant to thereservoir (page 6-8) to bring the fluid level inthe reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur- ther signs of overheating. If overheating hap-pens again, call a Hyundai dealer for assis-tance.
CAUTION:Serious loss of engine coolant indicates thereis a leak in the cooling system and this shouldbe checked as soon as possible by a Hyundaidealer. 2. The spare tire should only be used temporari-
ly and should be returned to the luggagecompartment as soon as the original tire canbe repaired or replaced.
3. Continuous use at speeds of over 80 km/h (50 mph) is not recommended.
4. As the temporary spare tire is specifically designed for your car, it should not be used onany other vehicle.
5. The temporary spare tire should not be used on any other wheels, nor should standardtires, snow tires, wheel covers or trim ringsbe used with the temporary spare wheel. Ifsuch use is attempted, damage to theseitems or other car components may occur.
6. The temporary spare tire pressure should be checked once a month while the tire is stored.
D040A01GK-GAT TEMPORARY SPARE TIREThe following instructions for the temporary spare tire should be observed:
1. Check inflation pressure as soon as practical
after installing the spare tire, and adjust to the specified pressure. The tire pressure shouldbe periodically checked and maintained atthe specified pressure while the tire is stored.
Spare Tire Pressure CAUTION:
o Do not use snow chains with your tempo-
rary spare tire.
o Do not use more than one temporary spare tire at a time.

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.

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.
