o Keep your car in good condition. For better fuel economy and reduced maintenance costs, maintain your car in accordance with the mainte- nance schedule in Section 6. If youdrive your car in severe conditions, more frequent maintenance is re- quired (see Section 6 for details).
o Keep your car clean. For maximum service, your Hyundai should bekept clean and free of corrosivematerials. It is especially important that mud, dirt, ice, etc. not be al- lowed to accumulate on the under-side of the car. This extra weight can result in increased fuel con- sumption and also contribute to cor-rosion.
o Travel lightly. Don't carry unneces-
sary weight in your car. Weight re-duces fuel economy.
o Don't let the engine idle longer than
necessary. If you are waiting (andnot in traffic), turn off your engine and restart only when you're ready to go. o Remember, your Hyundai does not
require extended warm-up. As soonas the engine is running smoothly, you can drive away. In very cold weather, however, give your enginea slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine.
Lugging is driving too slowly in toohigh a gear resulting in the engine bucking. If this happens, shift to a lower gear. Over-revving is racingthe 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 oper-ated by engine power so your fueleconomy is reduced when you use it.
o Don't "ride" the brake or clutch pedal.
This can increase fuel consumption and 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 effectiveness and may lead to more serious con-sequences.
o Take care of your tires. Keep them
inflated to the recommended pres-sure. Incorrect inflation, either too much or too little, results in unnec- essary tire wear. Check the tire 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 tire wearand may also result in other prob- lems as well as greater fuel con- sumption.

D170B01P-GAT (1) Speed Avoid rapid acceleration, sudden starts, and maximum speed driving; suchoperation will result in more fuel con- sumption. D170C01P-GAT (2) Shifting Shift only at an appropriate vehicle speed and engine rpm.Always use the highest gear possible. Fuel consumption depends largely on the manner in which vehicle is drivenbut it is also affected by other driving conditions. D170D01P-GAT (3) City traffic Frequent starting and stopping in- creases the average fuel consump- tion. Use roads with smooth traffic flowwhenever possible. When driving on congested roads, avoid use of a low gear at high engine rpm. D170G01P-GAT (6) Tire inflation pressure Check the tire inflation pressure at regular intervals. Low tire inflation pres- sures increase road resistance and fuel consumption. In addition, low tirepressures adversely affect tire wear and driving control.D170H01P-GAT (7) Load Do not drive with unnecessary articles in the luggage compartment.Especially during city driving where frequent starting and stopping is nec- essary, the increased weight of thevehicle will greatly affect fuel consump- tion. Also avoid driving with unnecessaryluggage, etc., on the roof; the increased air resistance will cause more fuel consumption.
D170I01P-GAT (8) Cold engine starting Starting of a cold engine consumes more fuel. Unnecessary fuel consump- tion is also caused by keeping a hot engine running. After the engine isstarted, begin driving soon.
D170E01P-GAT (4) Idling The vehicle consumes fuel even dur- ing idling. Avoid extended idling when-ever possible. D170F01P-GAT (5) High speed The higher the vehicles speed, the more fuel consumed. Avoid driving at full speed. Even a slight release of the accelerator pedal will save significant amount of fuel.

29WINTER DRIVING
D180A01P-GAT Engine oil The engine oil can become very thick at low temperatures, thus making itdifficult to start the engine. Change to a thinner oil designed for winter use before the start of coldweather; for the appropriate oil viscos- ity, refer to the "Consumer Informa- tion" section. D180B01P-GAT Engine coolant If the temperature in your area drops below freezing, there is the danger thatthe coolant in the engine or radiator could freeze and cause severe dam- age to the engine and/or radiator.Be sure to add a sufficient amount of antifreeze to the coolant to prevent it from freezing.The engine coolant mixture used at the factory is intended to be left in the cooling system and provides protec-tion against freezing for temperature as low as approximately -30°C (-20°F). The concentration should be checkedbefore the start of cold weather and anti-freeze added to the system if nec- essary.SMOOTH CORNERING
C150A01A-AAT Avoid braking or gear changing in cor- ners, especially when roads are wet. Ideally, corners should always be taken under gentle acceleration. If you followthese suggestions, tire wear will be held to a minimum.

D180C01P-GAT Battery The capacity of the battery is reduced at low temperatutes.This is an inevitable result of its chemi- cal and physical properties. This is why a very cold battery, particularlyone that is not fully charged anyway, will only deliver a fraction of the starter current which is normally available.It is recommended that you have the battery checked by an authorized HYUNDAI dealer before the start ofcold weather and, if necessary, have it charged. This not only ensures reliable starting,but a battery which is kept fully charged also has a longer life. C160G02A-AAT To Keep Locks from Freezing To keep the locks from freezing, squirt an approved de-icer fluid or glycerineinto the key opening. If a lock is cov- ered with ice, squirt it with an approved de-icing fluid to remove the ice. If thelock is frozen internally, you may be able to thaw it out by using a heated key. Handle the heated key with careto avoid burning your fingers. NOTE: The proper temperature for using the immobilizer key is from -40°C to 80°C. If you heat the immobilizer key over 80°C to open the frozenlock, it may cause damage to the transponder in its head.
D180G01P-GAT Door locks To prevent the door locks from freez- ing up, the lock cylinders should be masked with tape, etc., when washingthe vehicle in cold weather to prevent the entrance of water.
D180D01P-GAT Washer fluid To ensure proper operation of the wind- shield or rear window at low tempera-tures, anti-freeze should be added to the washer fluid at a rate of one part antifreeze to one part water. D180E01P-GAT Wiper blades Before operating the wipers, check the wiper blades to confirm that they arenot frozen to the windshield or tailgate. If the blades are frozen to the wind- shield or tailgate, do not operate thewipers until the ice has melted and the blades are freed. D180F01P-GAT Ventilation slots The ventilation slots in the headlight housing on the assistant seat side should be brushed clear after a heavysnowfall so that the operation of the heating and ventilation systems will not be impaired.

D180J01P-GAT Weather strip To prevent freezing of the weather strip on the doors, the roof, etc., theyshould be treated with silicone grease. D180K01P-GAT Snow tires The use of snow tires is recommended for driving in snow and ice. To pre- serve driving stability, mount snow tires of the same size and tread pattern onall four wheels. Snow tires worn more than 50% are no longer suitable for use as snow tires.Snow tires which do not meet specifi- cations must not be used. NOTE: The laws and regulations concern- ing snow tires (driving speed, re- quired use, type, etc.) vary. Find out and follow the laws and regula-tions in your area. D180L01P-GAT Tire chains If tire chains are to be used, be sure that they are mounted on the rearwheels. Use only tire chains which are de- signed for use with the tires mountedon the vehicle; use of the incorrect size or type of chain could result in damage to the vehicle body.Before driving over long stretches of road which are free of snow, you should remove the chains to avoid damage tothe tires. NOTE: The laws and regulations concern- ing tire chains vary. Find out and follow the laws and regulations in your area.
D180H01P-GAT Parking brake If the atmospheric temperature is be- low freezing, park the vehicle with thegearshift lever in 1st or reverse and do not engage the parking brake. If the parking brake is engaged and there ismoisture on the brake linings, the lin- ings could become frozen to the brake drums, making it impossible to releasethe parking brake. When parking on a steep slope, turn the front wheels in towards the kerband chock the wheels.
D180I01P-GAT Washing the vehicle The salt and other chemicals spread on winter roads in some areas can have a detrimental effect on a vehicle body. You should therefore wash thevehicle as often as convenient in ac- cordance with our care-instruction. Have a preservative applied and theunderfloor protection checked at an authorized HYUNDAI dealer before and after the cold weather season.

32LOCKING DIFFERENTIALADDITIONAL EQUIPMENT
D180M02P-GAT It is a good idea to carry a shovel or a short-handled spade in the vehicle during the winter so that you can clear away snow if you get stuck. A smallhand-brush for sweeping snow off the windscreen and rear window is also useful. D190A01HR-GAT (Minibus/van)(If Installed) A locking differential, if equipped, is for the rear wheel differential only. Thefeatures of this locking differential are described below: Just as with a conventional differential,the wheel on one side is allowed to turn at a different speed from the wheel on the other side when the vehicle iscornering. The difference between the locking differential and a conventional differential is that if the wheel on oneside of the vehicle loses traction, a greater amount of torque is applied to the rear wheel on the other side toimprove traction. NOTE: In a stationary position, the LD (Locking Differential) will operate when the difference of the revolu- tion speed between the rear rightwheel and the rear left wheel oc- curs.
CAUTION:(If installed)
White smoke may arise from thefuel fired heater outlet in the driver's front wheel housing during winterdriving. This is a normal condition. But, If a black (or gray) smoke is generated heavily, have the fuel firedheater checked by your Hyundai dealer. If the engine stops while the fuelfired heater is operating, whizzing noise may be heard from the lower of the battery in the engine com- partment. This is due to cleaning process forfuel fired heater and a normal op- eration. It will takes about 1- 3 minutes ac-cording to fuel quantity in the fuel fired heater fuel line.

33LIMITED-SLIP DIFFEREN- TIAL
CAUTION:
o Never start the engine with the gearshift lever placed in the for- ward or reverse while one of the rear wheels is jacked up and theother in contact with the ground; doing so may cause the vehicle to jump forward.
o If one of the rear wheels begins to spin in mud, snow, etc., thevehicle can sometimes be drivenout by depressing the accelera- tor pedal further; however, avoid running the engine continuouslyat high rpm because doing so could damage the locking differ- ential.
!
The following procedures can be used to confirm that the locking differentialis functioning properly:
(1) Position the vehicle so that one
wheel is on a dry paved surface and the other on ice, snow, mud, etc. Drive the vehicle, and observe theoperation of the locking differential. The vehicle should not become stuck if the differential is function-ing properly.
(2) Depress the accelerator pedal
gradually, and then when traction isgood, depress it forcefully. If the vehicle accelerates well, the differ- ential is functioning properly. D190A02P-GAT
(Truck)(If installed) A limited-slip differential, if equipped, is for the rear wheel differential only.The features of this limited-slip differ- ential are described below: Just as with a conventional differential,the wheel on one side is allowed to turn at a different speed from the wheel on the other side when the vehicle iscornering. The difference between the limited-slip differential and a conven- tional differential is that if the wheel onone side of the vehicle loses traction, a greater amount of torque is applied to the rear wheel on the other side toimprove traction. NOTE: In a stationary position, the L.S.D will operate when the torque differ- ence between the rear right wheel and the left wheel is from 5Kgf·m to9 Kgf·m.
