DRIVING YOUR HYUNDAI 2- 13
Driving on dry paved road and high- way
Select the AUTO to drive on dry paved roads.
Especially on dry highway, never select the LOW. Driving on snowy or icy roads
Select the AUTO or LOW in accordance with
the road conditions, and then gradually depress the accelerator pedal for a smooth start. Driving on sandy or muddy roads
Select the LOW and then gradually depress the
accelerator pedal for a smooth start. Keep the pressure on the accelerator pedal constant aspossible, and drive at low speed. Climbing sharp grades
Select the LOW to maximize use the engine
torque.Descending sharp grades
Select the LOW, use the engine brake and
descend slowly.
(8) For speedometer test or inspection/mainte- nance (I/M) program of full-time 4WD ve- hicle, use a four-wheel chassis dynamom-eter.
CAUTION: Never engage the parking brake whilst per-
forming these tests.
o In rare cases when it's unavoidable that a 4WD vehicle is to be inspected for speed- ometer test on 2WD roll tester, strictly followthe procedures next.
1. Check the tyre pressures recommended for your vehicle.
2. Place the rear wheels on the roll tester for speedometer test as shown in theillustration.
3. Release the parking brake.
4. Place the front wheels on the temporary free roller as shown in the illustration.
WARNING:Keep away from the front of the vehicle
whilst inspecting. This is very dangerous as the vehicle can jump forward and causeserious injury or death.
(9) When using tyre chains, always attach them to the rear wheels.
(10) I f the front or rear wheels get stuck in the
mud, do not spin them recklessly. The 4WD system could be damaged. Driving in Water Select the LOW mode and drive through slowly.
D090E01HP
The maximum advisable wading depth is ap-
proximately 40cm.
Before driving through water, such as when
crossing shallow streams, first check the depth of the water and the bottom of the river bed forfirmness. Drive slowly at the speed of 3mph(5 km/h) and avoid deep water.
Take all necessary safety measures to ensure
that water damage to the engine or other ve-hicle parts does not occur.
Water entering the engine air intake will cause
severe engine damage.
Water can wash the grease from wheel bear-
ings, causing rusting and premature failure, andmay also enter the axles, transmission andtransfer case, reducing the gear oil's lubricatingqualities.

LIMITED-SLIP DIFFERENTIAL (Not all models)
A limited-slip differential, if equipped, is for the
rear wheel differential only. The features of this limited-slip differential are described below:
Just as with a conventional differential, the
wheel on one side is allowed to turn at adifferent speed from the wheel on the other sidewhen the vehicle is cornering. The differencebetween the limited-slip differential and a con-ventional differential is that if the wheel on oneside of the vehicle loses traction, a greateramount of torque is applied to the rear wheel onthe other side to improve traction.

EFFECTIVE BRAKING Braking system performance and friction mate-rial life are greatly affected by the driving styleadopted. The following suggestions are madeto assist 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 tominimize 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.
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 thetransmission to overheat. Always use thebrake pedal or parking brake.
CAUTION:
o Whilst the full-time 4WD vehicle is being raised on a jack, never start the engine orcause the tyres to rotate. There is the danger that rotating tyres touching the ground could cause thevehicle to go off the jack and to jumpforward.
o If one of the front or rear wheels begins to spin in mud, snow, etc., the vehiclecan sometimes be driven out by depress-ing the accelerator pedal further; how-ever, avoid running the engine continu-ously at high rpm because doing so coulddamage the 4WD system.
WARNING:
o Avoid high cornering speeds.
o Do not make quick steering wheel move- ments, such as sharp lane charges or fast, sharp turns.
o The risk of rollover is greatly increased if you lose control of your vehicle at high-way speeds.
o In a collision crash, an unbelted person is significantly more likely to die than aperson wearing a seatbelt.
o Loss of control often occurs if two or more wheels drop off the roadway and thedriver oversteers to reenter the roadway.
o In the event your vehicle leaves the road- way, do not steer sharply. Instead, slowdown before pulling back into the travellanes.

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:

DRIVING FOR ECONOMY
You can save fuel and get more miles from your
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 cruisingspeed. Don't race between stoplights. Try toadjust your speed to that of the other trafficso you don't have to change speeds unnec-essarily. Avoid heavy traffic whenever pos-sible. Always maintain a safe distance fromother vehicles so you can avoid unneces-sary braking. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel your car uses. Driving ata moderate speed, especially on the high-way, is one of the most effective ways toreduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This can increase fuel consumption and alsoincrease wear on these components. In ad-dition, driving with your foot resting on thebrake pedal may cause the brakes to over-heat, which reduces their effectiveness andmay lead to more serious consequences.
o Take care of your tyres. Keep them inflated to the recommended pressure. Incorrect in-flation, either too much or too little, results inunnecessary tyre wear. Check the tyre pres-sures at least once a month. o Be sure that the wheels are aligned correct-
ly. Improper alignment can result from hittingcurbs or driving too fast over irregular sur-faces. Poor alignment causes faster tyrewear and may also result in other problemsas well as greater fuel consumption.
o Keep your car in good condition. For better fuel economy and reduced maintenancecosts, maintain your car in accordance withthe maintenance schedule in Section 5. Ifyou drive your car in severe conditions,more frequent maintenance is required (seeSection 5 for details).
o Keep your car clean. For maximum service, your Hyundai should be kept clean and freeof corrosive materials. It is especially impor-tant that mud, dirt, ice, etc. not be allowed toaccumulate on the underside of the car. Thisextra weight can result in increased fuelconsumption and also contribute to corro-sion.
o Travel lightly. Don't carry unnecessary weight in your car. Weight reduces 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 Hyundai does not require extended warm-up. As soon as the engineis running smoothly, you can drive away. Invery cold weather, however, give your en-gine a slightly longer warm-up period. o Don't "labour" or "over-rev" the engine.
Labouring is driving too slowly in too high agear resulting in the vehicle kangarooing. Ifthis happens, shift to a lower gear. Over-revving is racing the engine beyond its safelimit. This can be avoided by shifting at therecommended speeds.
o Use your air conditioning sparingly. The air conditioning system is operated by enginepower so your fuel economy is reducedwhen you use it.
C150A01A-EAT SMOOTH CORNERINGAvoid braking or gear changing in corners, especially when roads are wet. Ideally, cornersshould always be taken under gentle accelera-tion. If you follow these suggestions, tyre wearwill be held to a minimum.

To Clean Leather Upholstery
(Not all models) In the normal course of use, leather upholstered
surfaces will, like any material, pick-up dust and dirt. This dust and dirt MUST be cleaned off orit may work into the surface of the leather,causing damage.
Fine leather needs care. This care, as with all
fine things, need not be elaborated, but shouldinclude cleaning when necessary. Washingleather thoroughly with soap and water willkeep your leather lustrous, beautiful and ensureyou have many years of wear.
Take a piece of cheese cloth and using any
mild soap and lukewarm water, work up a goodlather. Thoroughly wash the leather. Wipe cleanwith a slightly damp cloth and dry with softcloth. Do this as often as the leather becomessoiled. During tanning operations, sufficient oils are
incorporated through processing that none needbe applied during the life of the leather. Oilapplied to the finished surface will in no wayhelp the leather and may do more harm thangood. Varnished and furniture polishes shouldNEVER be used under any conditions.

EMISSION CONTROL SYSTEMS 7-1
vehicle may be damaged. You should inspect the exhaust system each time the car is raisedfor lubrication or oil change. To check condition
1. Holes and gas leaks due to corrosion, dam-
age, etc., should be rectified.
2. The joints should be checked for loose con- nections and gas leakage.
3. The hanger rubber and brackets should be checked for damage. DH010B1-E
1. CRANKCASE EMISSION CONTROL
SYSTEM ; For a Petrol Engine
The positive crankcase ventilation system is
employed to prevent air pollution caused by blow-by gases being emitted from the crank-case.
This system supplies fresh air to the crankcase
through the air cleaner. Inside the crankcase,the fresh air mixes with blow-by gases, thenpasses through the PCV valve into the intakesystem.
ZH010C1-E
2. EVAPORATIVE EMISSION CON-
TROL SYSTEM ; For a Petrol Engine
The Evaporative Emission Control System is designed to prevent fuel vapors from escapinginto the atmosphere.
Canister While the engine is inoperative, fuel vaporsgenerated inside the fuel tank are absorbed andstored in the canister. When the engine isrunning, the fuel vapors absorbed in the canis-ter are drawn into the induction system throughthe purge control solenoid valve.

EXHAUST GAS WARNING
Exhaust gases contain carbon monoxide, a
potentially toxic gas that is colorless and odor-less. Avoid breathing exhaust gases.
o Do not run the engine in confined areas, such as garages, any longer than neces- sary to move the car in or out.
o Do not drive with the trunk open. An open trunk may draw exhaust gases into the pas-senger compartment. If you must drive withthe trunk open, drive only with all the win-dows wide open and the blower motor onhigh speed.
o If it is necessary to sit in a parked car with the engine running for more than a shortperiod, adjust your heating system to forceoutside air into the car by placing the airselector button of the heater in the FRESHAIR position and mode control in the VENTposition. Set the fan at high speed and thecontrols in any position desired.
Inspect the exhaust system Whenever a change is noticed in the sound of
the exhaust system, the underside or rear of the ZH010A1-E EMISSION CONTROL SYSTEMS (Not all models) Your Hyundai is equipped with an emission control systems. There are three emission control systems which are as follows. (1) Crankcase emission control system (2) Evaporative emission control system(3) Exhaust emission control system In order to assure the proper function of the emission control system, it is recommendedthat you have your car inspected and main-tained by an authorized Hyundai dealer in ac-cordance with the schedule in this manual.
