SB215F1-E TACHOMETER
SB215B1-E ENGINE COOLANT TEMPERATURE GAUGE engine is hot may cause hot water and steam to be ejected from the radiator resulting in burns and scalding. The radiator cap must only be removed when the engine has cooled. Do not add cold water to a hot engine to avoid the possibility of engine damage. The use of plain water in the cooling system is not rec- ommended since the aluminium components of the cooling system require the use of a corrosion inhibitor found in the recommended Ethylene Glycol type anti freeze solutions.
The engine coolant temperature gauge indicates the engine coolant temperature and will, under normal circumstances, give an indication in the "Normal" or centre portion of the scale. Should the indication move into the upper or "Hot" por- tion of the scale, engine overheating is indicated. Under these circumstances, the vehicle should be brought to rest as soon as is safe to do so and the engine turned off. Once the engine has cooled somewhat, the coolant level and the condition of the generator/water pump drive belt should be checked. If the cause of the overheating cannot be readily established, the assistance of a Hyundai dealer should be sought. WARNING: The engine cooling system is pressurized and removal of the radiator cap when the The tachometer registers the speed of the engine in revolutions per minute (R.P.M.). CAUTION: The maximum safe engine operating speed is indicated by the white zone of the tachometer scale. The engine should not be operated beyond the beginning of this zone or serious engine damage may result.
SB215C1-E SPEEDOMETER The speedometer indicates the vehicle speed in both miles and kilometres per hour.

DRIVING YOUR HYUNDAI 2- 11
o Remember, your car does not require ex-
tended warm-up. As soon as the engine is running smoothly, you can drive away. In very 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 at the recommended speeds.
o Use your air conditioning sparingly. The air conditioning system is operated by the en-gine power so your fuel economy is reduced when you use it.
SC160A1-F SMOOTH CORNERINGAvoid braking or gear changing in corners, especially when roads are wet. Ideally, corners should always be taken under gentle accelera- tion. If you follow these suggestions, tire wear will be held to a minimum. SC170A1-E WINTER MOTORINGThe onset of winter conditions subject motor vehicles to greater operating demands. There- fore, the following suggestions will assist in maintaining peak performance and reliability during these periods: ZC170B1-E Electrical SystemWinter conditions impose severe demands upon vehicle electrical systems, particularly the charg- ing circuit. The battery condition and perfor- mance along with the alternator performance and drive belt condition should be checked prior to the onset of winter. ZC170C1-E Anti-freeze/Corrosion inhibitorThe 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 be checked 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 the engine. Therefore, never, drain the system and 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 and subsequently bursting with the refrigeration sys- tem in use.
ZC170D1-E Door LocksShould the door lock mechanism become fro- zen, a proprietary lock de-icer should be used. Alternatively, warming the door key may thaw the door lock. However, the key should be handled carefully to avoid burning the fingers. Never attempt to thaw a frozen door lock using hot water, since the water will eventually freeze and 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 over 176°F (80°C) to open the frozen lock, it may cause damage to the transponder in its head. SC170E1-E Windscreen Washers and WipersThe windscreen washer bottle should be filled with a solution of water and a proprietary winter screen wash additive. The windscreen wipers should not be used if the blades are frozen to the windscreen or if they are covered with snow, 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 to the paintwork may result.

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 cold water to be draining from it).
WARNING: Whilst the engine is running, keep hands and clothing away from moving parts such as the 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 dealer for assistance.
WARNING:Do not remove the radiator cap when the engine is hot since steam and boiling water may be ejected from the radiator resulting in burns 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 been lost, carefully remove the radiator cap and add 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 halfway mark.
WARNING: Motor vehicle batteries contain sulphuric acid and emit hydrogen gas. Protective clothing should be worn and care exercised to prevent the acid from coming into contact with skin or clothing and the vehicle. Naked lights should not be permitted in the vicinity of the battery. Care should be exercised to prevent sparks occurring during connection. If acid acciden- tally comes into contact with skin or eyes, the affected area should immediately be flushed with copious amounts of water 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 vehicles are not touching.
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 other end to the positive (+) terminal of the dis- charged battery.
5. Attach the black jump cable to the negative
(-) terminal of the booster battery, and the other end to a ground point within the engine compartment of the vehicle with the flat bat- tery. Do not connect to the negative battery terminal of the flat battery since sparks may be generated with the subsequent risk of explosion. 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 components such as the Fuel Injection system computer and the Automatic Transmission computer. The battery must never be disconnected whilst the 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 bonnet stop the engine. Do not open the bonnet until the cool-ant has stopped running or the steam- ing has stopped. If there is no visible loss of coolant and no steam, leave the engine run- ning and check to be sure the engine cooling fan is operating. If the fan is not running, turn the engine off.

IN CASE OF EMERGENCY
SD060A1-E IN THE EVENT OF A PUNCTURE If 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 ofbraking required which will assist in main- taining the maximum amount of control. The vehicle should be parked wherever possible upon firm level ground to facilitate wheel changing.
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 a Hyundai dealer should be sought.
CAUTION: Serious loss of coolant indicates there is a leak in the cooling system and this should be checked as soon as possible by a Hyundai dealer.
It is of the utmost importance that care is exer- cised when changing road wheels. Ensure that the parking brake is set and that the gear shift lever is in reverse (P, if the vehicle has automatic transmission).
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 should be periodically checked and maintained at the 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 can be 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 standard tyre, snow tyre, wheel covers or trim rings be used with the temporary spare wheel. If such use is attempted, damage to these items or other car components may occur.
6. The temporary spare tyre pressure should be checked once a month while the tyre is stored.
CAUTION:
o Do not use snow chains with your tempo- rary spare tyre.
o Do not use more than one temporary spare
tyre at a time.

SG020B1-E DAILY OPERATING CHECKS The following items should be checked on a daily basis or whenever the vehicle is refuelled, which- ever occurs sooner.
o Engine oil level.
o Engine coolant level.
o Power steering fluid level.
o Brake fluid level.
o Windscreen washer fluid level.
o Battery condition.
o Tyre condition and pressures.
o Operation and cleanliness of all lighting equip-
ment.
o Windscreen wiper and washer operation.
o Horn operation.
o Warning lamp operation.
o Adjustment and cleanliness of mirrors.
o Seat and seat belt adjustment and operation.
o Fluid leakage. The vehicle must not be driven if the daily oper- ating checks indicate that any item of equipment related to the safety or roadworthiness of the vehicle is not functioning correctly. SG030A1-E ENGINE OIL The correct engine oil level is of paramount importance. An excessively high or low oil level may result in irreparable damage being sus- tained by the engine. The engine oil level must be checked on a daily basis or whenever the vehicle is refuelled, whichever occurs sooner. In addition, it is imperative that only an approved grade and specification of oil is used to avoid the possibility of serious engine damage and prema- ture wear. The use of "budget price" oil is a false economy that must be avoided if the maximum reliability and useful life is to be obtained from the vehicle.
SG030B02GK-E Recommended Oil A multi grade oil having a specification which meets A.P.I. specification of SH, SG or above is recommended. The oil viscosity should be se- lected according to the operating environment of the engine by means of the table shown below. The engine oil recommendations are complete in themselves and the use of additives is neither required nor recommended. The use of engine oil additives may result in invalidation of the vehicle warranty.

ways wash thoroughly after any contact. Keep used oils out of reach of children. It is illegal to pollute drains, water courses and soil. Use only authorized waste collection facilities including civic amenity sites and garages for the disposal of used oil and oil filters. If in doubt, contact the local authority for dis- posal instructions. SG050A1-E ENGINE COOLANT CHECKING AND REPLACING WARNING: Do not remove the radiator cap when the engine is hot, since the system is pressurized and coolant may be ejected from the radiator resulting in scalding. SG050B1-E Coolant recommendations
Only ethylene glycol based coolant with a corro- sion inhibitor suited to aluminium alloy engine components should be used in the cooling sys- tem. No further additives or inhibitors should be used. The coolant specific gravity should be checked as prescribed in the maintenance sched- ule to ensure adequate frost and corrosion pro- tection. In addition, the engine coolant must be replaced at the specified interval since the corro- sion inhibitor properties deteriorate with time. It is important to note that whilst an increase in the concentration of anti freeze gives an increase in the level of frost protection, a solution which is in excess of 65% anti freeze will result in reduced frost 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 will invalidate the vehicle warranty. NOTE: It is imperative that vehicles fitted with an air conditioning system have a coolant concen- tration of the recommended strength at all times. The use of the air conditioning system when the cooling system is filled with water only will result in the heater matrix freezing and subsequently bursting.SG050C1-E Engine Coolant Level The engine coolant level may be observed through the side of the plastic coolant reservoir (expansion tank) when the engine is cold. If the level is below the "LOW" mark, add coolant of the correct concentration until the level is between the "LOW" and "Full" marks. If the level falls below the "LOW" mark on a regular basis despite being topped up, consult a Hyundai dealer. SG050D1-E To Change the Engine Coolant The engine coolant should be changed at those intervals specified in the vehicle maintenance schedule in Section 5. NOTE: Care should be taken to ensure that coolant is not allowed to spill onto the paintwork since the finish may become damaged. If coolant spillage occurs, the affected area should 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 OPERATION WHILST THE ENGINE IS HOT SINCE BURN-ING OR SCALDING MAY RESULT.
2. Prepare a suitable receptacle to collect the displaced coolant and position this under the radiator drain tap.
