REPLACING THE SPARK PLUGS The spark plugs should be changed at theintervals specified in the vehicle maintenancesschedule in Section 5 or whenever engine per-formance indicates they should be changed.Symptoms that suggest poor spark plug perfor-mance include engine misfiring under load, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother spark plugs can result in loss of perfor-mance, radio interference or engine damage. NOTE: When replacing the spark plugs, genuine Hyundai replacement parts are recom-mended. Recommended Spark Plugs:
SSA6060A
Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)

5. Start the engine, top off the radiator with
water and then add engine coolant to the reservoir until the level is between "LOW"and "FULL".
6. Replace the radiator and reservoir caps and check to be sure the drain cocks are fullyclosed and not leaking.
WARNING: The cooling fan is controlled by engine cool- ant temperature and may sometimes oper-ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition.

1. Open the hood, being careful to keep hands,
long hair and clothing clear of any moving parts.
2. Remove the transaxle dipstick, wipe it clean, reinsert the dipstick as far as it will go, thenremove it again. Now check the fluid level onthe dipstick. It should be in the "HOT" rangeon the dipstick.
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipsticktube until the level reaches the "HOT" range.Do not overfill.Fluid level should be within this range

NORMAL CONDITIONS The Starting Procedure:
1. Insert key, and fasten the seat belt.
2. Depress the clutch pedal fully and place the gearshift lever (manual transaxle) in neutral or the selector lever (automatictransaxle) in "P" (park) position.
3. After turning the ignition key to the "ON" position, make certain all warning lightsand gauges are functioning properly be-fore starting the engine.
4. On vehicles equipped with the diesel pre- heat indicator light, turn the ignition key tothe "ON" position. The diesel pre-heat indi-cator light will first illuminate in amber, andthen after a short time, the amber illumina-tion will goes off, indicating that preheatingis completed. SC060B1-E FUEL ECONOMY
The following suggestions are made to assist in achieving the greatest degree of fueleconomy.
o Maintaining a constant check on fuel con- sumption will enable the most economicaluse pattern and driving style to be adopt-ed.
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 aspossible after use.
o Anticipate the road and conditions ahead to enable adjustments in speed to be madesmoothly. Avoid heavy acceleration andsharp braking.
NOTE: If the engine were not started 10 seconds
after the preheating is completed, turn the ignition key once more to the "LOCK"position, and then to the "ON" position, inorder to preheat again.
WARNING: Be sure that the clutch is fully depressed
when starting a manual transaxle vehicle. Otherwise there is the potential to cause damage to the vehicle or injury to some-
one inside or outside the vehicle as aresult of the forward or backward move-ment of the vehicle that will occur if theclutch is not depressed when the vehicle isstarted.
5. Turn the ignition key to the "Start" position and release it when the engine starts.

STARTING AND STOPPING THE EN- GINE FOR TURBO CHARGER INTER- COOLER (DIESEL ENGINE)
(1) Do not race the engine or sudden acceler-
ate the engine immediately after start it. If the engine is cold, allow the engine to idlefor several seconds before it is driven toensure sufficient lubrication of the turbocharger unit.
(2) After high speed or extended driving, re- quiring a heavy engine load, the engineshould be allowed to idle about 1 minutebefore turning it off. This idle time will allow the turbo charger tocool prior to shutting the engine off.
WARNING: Do not turn the engine off immediately after it has been subjected to a heavy load.Doing so may cause severe damage to theengine or turbo charger unit.

OVERDRIVE SWITCH
The overdrive switch prevents the transaxle
upshifting higher than third gear when the switch is turned "OFF". The transaxle will startfrom rest in first gear and upshift to secondand third gear depending upon the roadspeedand throttle opening but will not upshift tofourth gear. When the overdrive switch isturned "ON", the transaxle will start from restin first gear and will upshift, depending uponroadspeed and throttle opening to second,third and fourth gear. Therefore, when theoverdrive switch is turned "OFF", the transaxleperforms as a three speed unit and the over-drive warning light located in the instrumentcluster will be illuminated. When the overdriveswitch is turned "ON", the transaxle functionsas a fully automatic four speed unit with themaximum fuel economy potential of the ve-hicle being realized. o Do not hold the vehicle on the upgrade
with the accelerator pedal. This can causethe transmission to overheat. Always usethe brake pedal or parking brake.
SC140A1-E EFFECTIVE BRAKING Braking system performance and friction ma- terial life are greatly affected by the drivingstyle adopted. The following suggestions aremade to assist in achieving the best resultsfrom the braking 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 oc-curring.
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 consis-tent friction 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 waterand dry the brakes by lightly depressingthe brake pedal several times whilst driv-ing slowly.
o Apply the parking brake only when the vehicle 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 tow-ing of the vehicle with the engine turned offwill result in greatly increased pedal pres-sures being required to stop the vehicle. SC140B1-E
ANTI-LOCK BRAKE SYSTEM (Not all models)
The Anti-Lock Brake System (ABS) is de-
signed to prevent wheel lock-up during sud- den braking or on hazardous road surfaces.The ABS control module monitors the wheelspeed and controls the pressure applied toeach brake. Thus, in emergency situations oron slick roads, ABS will increase vehicle con-trol 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 whilstbraking. These conditions are normal andindicate that the anti-lock brake system isfunctioning properly.
WARNING:ABS will not prevent accidents due to im-
proper 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.

DRIVING YOUR HYUNDAI 2- 11
o Don't "lug" or "over-rev" the engine. Lug-
ging is driving too slowly in too high a gear resulting in the engine bucking. If thishappens to you, shift to a lower gear. Over-revving is racing the engine beyond its safe limit. This can be avoided byshifting at the recommended speeds.
o Use your air conditioning sparingly. The air conditioning system is operated by theengine power so your fuel economy isreduced when you use it.
SC150A1-F
DRIVING FOR ECONOMY
You can save fuel and get more miles fromyour 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 cruis-ing speed. Don't race between stoplights.Try to adjust your speed to that of the othertraffic so you don't have to change speedsunnecessarily. Avoid heavy traffic whenever possible. Al- ways maintain a safe distance from othervehicles so you can avoid unnecessarybraking. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel your car uses. Drivingat a moderate speed, especially on thehighway, is one of the most effective waysto reduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This can increase fuel consumption and alsoincrease wear on these components. Inaddition, driving with your foot resting onthe brake pedal may cause the brakes tooverheat, which reduces their effective-ness and may lead to more serious con-
sequences.
o Take care of your tyres. Keep them inflated to the recommended pressure. Incorrectinfla-tion, either too much or too little, re-sults in unnecessary tyre wear. Check thetyre 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 irregu-lar surfaces. Poor alignment causes fastertyre wear and may also result in otherproblems as well as greater fuel consump-tion.
o Keep your car in good condition. For better fuel economy and reduced maintenancecosts, maintain your car in accordancewith the maintenance schedule in Section5. If you drive your car in severe condi-tions, more frequent maintenance is re-quired (see Section 5 for details).
o Keep your car clean. For maximum ser- vice, your car should be kept clean andfree of corrosive materials. It is especiallyimportant that mud, dirt, ice, etc. not beallowed to accumulate on the underside ofthe car. This extra weight can result inincreased fuel consumption and also con-tribute to corrosion.
o Travel lightly. Don't carry unnecessary weight in your car. Weight is an enemy ofgood fuel economy.
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 extended warm-up. As soon as the engineis running smoothly, you can drive away.In very cold weather, however, give yourengine a slightly longer warm-up period. SC160A1-F SMOOTH CORNERING Avoid braking or gear changing in corners, especially when roads are wet. Ideally, cor-ners should always be taken under gentleacceleration. If you follow these suggestions,tyre wear will 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:

IN CASE OF EMERGENCY
WARNING: While the engine is running, keep hands
and clothing away from moving parts such as the fan and drive belts to preventinjury.
WARNING (Diesel only): Never work on injection system with en-
gine running or within 30 seconds after shutting off engine. High pressure pump,rail, injectors and high pressure pipes aresubject to high pressure even after theengine stopped. The fuel jet produced byfuel leaks may cause serious injury, if ittouch the body. People using pacemak-ers should not move than 30cm closer tothe ECU or wiring harness within theengine room while engine is running,since the high currents in the CommonRail system produce considerable mag-netic fields.
5. If the water pump drive belt is broken or coolant is leaking out, stop the engine immediately and call the nearest Hyundaidealer for assistance.
WARNING: Do not remove the radiator cap when the
engine is hot since steam and boiling wa- ter may be ejected from the radiator result-ing in burns or scalding. D040A01FC-EAT TEMPORARY SPARE TYREThe following instructions for the temporary spare tyre should be observed:
1. Check inflation pressure as soon as pos-
sible after installing the spare tyre, and adjust to the specified pressure. The tyrepressure should be periodically checkedand maintained at the specified pressurewhile the tyre is stored. 2. The spare tyre should only be used tem-
porarily and should be returned to theluggage compartment as soon as the origi-nal tyre can be repaired or replaced.
3. Continuous use at speeds of over 80 km/h (50 mph) is not recommended.
4. As the temporary spare tyre is specifically designed for your car, it should not beused on any other vehicle.
5. The temporary spare tyre should not be used on any other wheels, nor shouldstandard tyre, snow tyre, wheel covers ortrim rings be used with the temporaryspare wheel. If such use is attempted,damage to these items or other car com-ponents may occur.
6. The temporary spare tyre pressure should be checked once a month while the tyre isstored.
CAUTION:
o Do not use snow chains with your tem- porary spare tyre.
o Do not use more than one temporary spare tyre at a time.
Spare Tyre Pressure

found, wait until the engine temperature has returned to normal. Then, if coolanthas been lost, carefully remove the radia-tor cap and add water to bring the fluid levelin the reservoir up to the base of theradiator fill opening. Fill the coolant expan-sion tank to the halfway mark.
7. Proceed with caution until it is established that the engine is operating normally. If theengine overheats repeatedly, the advice ofa Hyundai dealer should be sought.
CAUTION: Serious loss of coolant indicates there is a leak in the cooling system and thisshould be checked as soon as possibleby a Hyundai dealer.
