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 engineturned off or towing of the vehicle with the engine turned off will result in greatly increased pedal pressuresbeing required to stop the vehicle.
o Do not hold the vehicle on an incline
with the accelerator pedal. This cancause the transmission to overheat. Always use the brake pedal or park- ing brake.
o Use caution when parking on a hill. Engage the parking brake and placethe gear selector lever in "P" (auto-matic transaxle) or in first or reverse gear (manual transaxle). If your car is facing downhill, turn the frontwheels into the curb to help keep the car from rolling. If your car is facing uphill, turn the front wheels awayfrom the curb to help keep the car from rolling. If there is no curb or if it is required by other conditions tokeep the car from rolling, block the wheels.DRIVING FOR ECONOMY
C140A02A-EAT You can save fuel and get more miles from your car if you follow these sug- gestions:
o Drive smoothly. Accelerate at a moderate rate. Don't make "jack- rabbit" starts or full-throttle shiftsand maintain a steady cruising speed. Don't race between stoplights. Try to adjust your speed to that of the othertraffic so you don't have to change speeds unnecessarily. Avoid heavy traffic whenever possible. Alwaysmaintain a safe distance from other vehicles so you can avoid unneces- sary braking. This also reduces brakewear.
o Drive at a moderate speed. The faster
you drive, the more fuel your caruses. Driving at a moderate speed, especially on the motorway, is one of the most effective ways to reducefuel consumption.
o Don't "ride" the brake or clutch pedal.
This can increase fuel consumptionand also increase wear on these components. In addition, driving with your foot resting on the brake pedalmay cause the brakes to overheat, which reduces their effectivenessand may lead to more serious conse-quences.
o Take care of your tyres. Keep them
inflated to the recommended pres-sure. Incorrect inflation, either too much or too little, results in unneces- sary tyre wear. Check the tyre pres-sures at least once a month.
o Be sure that the wheels are aligned
correctly. Improper alignment canresult from hitting curbs or driving too fast over irregular surfaces. Poor alignment causes faster tyre wearand may also result in other prob- lems as well as greater fuel con- sumption.
o Keep your car in good condition. For better fuel economy and reducedmaintenance costs, maintain yourcar in accordance with the mainte- nance schedule in Section 5. If you drive your car in severe conditions,more frequent maintenance is re- quired (see Section 5 for details).

YC200C4-E Trailer Brakes If your trailer is equipped with a braking system, make sure it conforms to localregulations and that it is properly in- stalled and operating correctly. NOTE: If you tow a trailer or vehicle, your car will require more frequent main- tenance due to the additional load.See Maintenance Under Severe Us- age Conditions" on page 5-7.
YC200B2-E Trailer Towbars Select the proper towbar and ball com- bination, making sure that its location is compatible with that of the trailer or vehicle being towed.Use a quality non-equalizing towbar which distributes the nose weight uni- formly throughout the chassis. The towbar should be bolted securely to the car and installed by a qualifiedtechnician.
CAUTION:
o Never connect a trailer brake sys- tem directly to the vehicle brakesystem.
o When towing a trailer on steep grades (in excess of 6%) pay closeattention to the engine coolanttemperature gauge to ensure the engine does not overheat. If the needle of the coolant temperaturegauge moves across the dial to- wards "H" (HOT), pull over and stop as soon as it is safe to do so,and allow the engine to idle until it cools down. You may proceed once the engine has cooled suffi-ciently.

13. Avoid holding the brake pedal downtoo long or too frequently. This could cause the brakes to overheat, re- sulting in reduced braking efficiency.
14. When going down a hill, shift into a
lower gear and use the engine brak-ing effect. When climbing a long grade, down-shift the transaxle to a lower gear and reduce speed to reduce chances of engine overloading and/or over-heating.
15. If you have to stop whilst going
uphill, do not hold the vehicle inplace by pressing on the accelera- tor. This can cause the automatic transaxle to overheat. Use the park-ing brake or footbrake.
NOTE: When towing, check transaxle fluid more frequently.
8. When parking your car and trailer,
especially on a hill, be sure to followall the normal precautions. Turn your front wheels into the curb, set the parking brake firmly, and put thetransaxle in 1st or Reverse (manual) or Park (automatic). In addition we advise the use of wheel chocks ateach of the trailer's tyres.
9. If the trailer has electric brakes, start
your vehicle and trailer moving, andthen apply the trailer brake controller by hand to be sure the brakes are working. This lets you check yourelectrical connection at the same time.
10. During your trip, check occasionally to be sure that the load is secure,and that the lights and any trailer brakes are still working.
11. Avoid jerky starts, sudden accel- eration or sudden stops.
12. Avoid sharp turns and rapid lane changes.
YC200E3-E Trailer or Vehicle Towing Tips
1. Before towing, check towbar ball and
safety cable connections as well as proper operation of the trailer running lights, brake lights, and turn signals.
2. Always drive your vehicle at a mod-
erate speed (Less than 60 mph).
3. Trailer towing requires more fuel than
normal conditions.
4. To maintain engine braking effi- ciency, do not tow a trailer with the transaxle in fifth gear (manual transaxle) or overdrive (automatic transaxle).
5. Always secure items in the trailer to prevent load shift whilst driving.
6. Check the condition and air pressure of all tyres on the trailer and your car. Low tyre pressure can seriously af- fect the handling. Also check thespare tyre.
7. The vehicle/trailer combination is
more affected by crosswind and buf-feting. When being passed by a large vehicle, keep a constant speed and steer straight ahead. If there is toomuch wind buffeting, slow down to get out of the other vehicle's air turbulence.

CAUTION:
If overheating should occur when towing, (temperature gauge reads near red zone), taking the followingaction may reduce or eliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. Whilst in stop and go traffic, place
the gear selector in park or neutraland idle the engine at a higher speed.

7. Switch "ON" the main beam
headlamps before carefully remov- ing the jumper cables have been removed, switch "OFF" the main beam headlamps. SD040A2-E If 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"
(automatic), 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 fromunder the bonnet stop the engine. Do not open the bonnet until thecoolant has stopped running or the steaming has stopped. If there is no visible loss of coolant and no steam,leave the engine running and check to be sure the engine cooling fan is operating.If the fan is not running, turn the engine off.
4. Check to see if the water pump drive belt is broken. If it is not missing,check to see that it is tight. If the drive belt seems to be satisfactory,check for coolant leaking from the radiator, hoses or under the car. (If the air conditioning had been in use,it is normal for cold water to be draining from it).
IF THE ENGINE OVERHEATS
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 touch- ing.
2. Turn off all unnecessary electrical equipment in both vehicles.
3. Ensure that the engine of the ve- hicle providing the jump start is run- ning prior to connection of the jump cables.
4. Connect the red jump cable to the positive (+) terminal of the boosterbattery and the other end to thepositive (+) terminal of the dis- charged battery.
5. Attach the black jump cable to the negative (-) terminal of the boosterbattery, and the other end to a ground point within the engine compartmentof the vehicle with the flat battery. Do not connect to the negative battery terminal of the flat battery sincesparks may be generated with the subsequent risk of explosion.
6. Raise the booster vehicle engine speed to 2,000 r.p.m. and start theengine of the vehicle with the flat battery. CAUTION:
If the jump cables are incorrectlyinstalled, damage to the vehicle elec-trical system may occur, in particu- lar the electronic components such as the Fuel Injection system com- puter and the Automatic Transaxle computer. The battery must neverbe disconnected whilst the engine is running.

!WARNING:
Whilst the engine is running, keep hands and clothing away from mov- ing 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 immediately and call the near- est Hyundai authorised repairer forassistance.
WARNING:
Do not remove the radiator cap when the engine is hot since steam and boiling water may be ejected fromthe radiator resulting in burns or scalding.
!
6. If the cause of the overheating can- not be found, wait until the engine temperature has returned to normal. Then, if coolant has been lost, care- fully add coolant to the reservoir(page 6-10) to bring the fluid level in the reservoir up to the base of the radiator fill opening. Fill the coolantexpansion tank to the halfway mark. To ensure the correct water to cool- ant mix is obtained after top up,testing by an authorised repairer is required.
7. Proceed with caution until it is estab- lished that the engine is operatingnormally. If the engine overheats repeatedly, the advice of a Hyundaiauthorised repairer should be sought.
CAUTION:
Serious loss of coolant indicates there is a leak in the cooling system and this should be checked as soonas possible by a Hyundai authorised repairer.D040A01GK-EAT The following instructions for the tem- porary 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 main- tained at the specified pressure whilst the tyre is stored.
TEMPORARY SPARE TYRE
Tyre Size
Inflation Pressure T125/70 R16
420 kPa (60 psi)

2. The spare tyre should only be used temporarily and should be returned to the luggage compartment as soonas the original tyre can be repaired or replaced.
3. Continuous use at speeds of over 50 mph (80 km/h) is not recom-mended.
4. As the temporary spare tyre is spe- cifically designed for your car, itshould not be used on any other vehicle.

ENGINE COOLANT CHECKING AND REPLACING
SG050A1-E
WARNING:
Do not remove the radiator cap
when the engine is hot, since the system is pressurised and coolant may be ejected from the radiator resulting in scalding. NOTE: It is imperative that vehicles fitted with an air conditioning systemhave a coolant concentration of the recommended strength at all times. The use of the air condition-ing system when the cooling sys- tem is filled with water only will result in the heater matrix freezingand subsequently bursting.
SG050B1-E
Coolant recommendations
Only ethylene glycol based coolantwith a corrosion inhibitor suited to aluminium alloy engine components should be used in the cooling system.No further additives or inhibitors should be used. The coolant specific gravity should be checked as pre-scribed in the maintenance schedule to ensure adequate frost and corro- sion protection. In addition, the en-gine coolant must be replaced at the specified interval since the corrosion inhibitor properties deteriorate withtime.It is important to note that whilst anincrease in the concentration of anti freeze gives an increase in the level of frost protection, a solution which isin excess of 65% anti freeze will result in reduced frost protection and engine overheating. Therefore therecommended concentration of 50% should not be exceeded for general use. The use of methanol based anti freeze compounds may result in engine over- heating and will invalidate the vehiclewarranty.
