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.

TCS ON Mode In the TCS ON mode, the indicator in the instrument cluster will not be illuminated. NOTE:
1) Turn off the engine. Then restart the engine, and the TCS mode will auto- matically turn "ON".
2) When the traction control is operating properly, you can feel a slight pulsationin the vehicle. This is only the effect ofbrake control and indicates nothingunusual. C300D02O-GAT
Indicator and Warning
The indicator should illuminate when the igni-tion key is turned to "ON" or "START", butshould go out after three seconds. If the indicator does not illuminate, have it checked by an authorized Hyundai dealer. Should there be any unusual conditions in the device, TCS illuminates as a warning.If TCS illuminates, pull your car to a safeplace and stop the engine. Then, start the engine again to check if the TCS indicator goes out. If the indicator remains lit even after the engine has been started, have your carchecked by an authorized Hyundai dealer. NOTE: When TCS illuminates, traction control is automatically deactivated for safety.
Driving hints
TCS does not actively apply brakes. Be sure
to decelerate the car sufficiently before enter-ing curves.
CAUTION: When the TCS indicator blinks, SLIP con-
trol has been activated. It also means that the road is slippery or your car is acceler-ating excessively. In this situation, releasefoot pressure from the accelerator pedaland maintain moderate speed.
WARNING: Traction control is only a driving aid; all
normal precautions for driving in inclem- ent weather and on slippery driving sur-faces should be observed. 3) When the engine starts, a click is heard
from the engine compartment; however,this is only the sound of traction controlbeing checked.
4) When moving out of the mud or fresh snow, pressing the accelerator pedalmay not cause the engine speed toincrease.
The braking distance for cars equippedwith an anti-lock braking system may belonger than for those without it in thefollowing road conditions.
o Driving on rough, gravel or snow-cov-
ered roads.
o Driving with tyre chains installed.
o Driving on roads where the road sur- face is pitted or has different surface height.
These roads should be driven at reducedspeeds. The safety features of an ABSequipped vehicle should not be tested byhigh speed driving or cornering. This couldendanger the safety of yourself or others.
C300A01O-EAT
BRAKE TRACTION CONTROL SYSTEM (BTCS) (Not all models)
On slippery road surfaces, the traction control
system (TCS) limits the drive wheels from spinning excessively, thus helping the car toaccelerate. It also provides sufficient drivingforce and steering performance as the carturns at accelerated speeds. SLIP Control
Limits the drive wheels from spinning exces-
sively during starting or while making acceler- ated turns on slippery roads to avoid losingthe driving force of the front wheels.

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:

DRIVING YOUR HYUNDAI
2- 12 NOTE: Never allow undiluted screen washer fluid additive to spill upon the paintwork or useengine coolant anti-freeze since damage tothe paintwork may result.
o When driving in extreme conditions, the windscreen wiper blades may fail to clearthe screen properly due to the formation ofice upon the blade edge. It will therefore benecessary to periodically remove such iceto restore their efficiency.
o If the power operated door mirrors become frozen, attempts to adjust these may dam-age the mechanism.
o The formation of snow or ice built up inside the wheel arches may interfere with theroad wheels or steering mechanism. Insuch instances, unusual noises or an in-crease in steering effort may result. There-fore, ensure that the wheel arches arechecked periodically and any accumulatedsnow or ice removed.
o It is advisable to carry emergency equip- ment including, torch, shovel, tow rope,blankets etc., if a journey is to be under-taken into areas of severe road conditions.
ZC170D1-E
Door Locks
Should the door lock mechanism becomefrozen, a proprietary lock de-icer should beused. Alternatively, warming the door keymay thaw the door lock. However, the keyshould be handled carefully to avoid burningthe fingers. Never attempt to thaw a frozen door lock using hot water, since the water will eventu-ally freeze and compound the problem. NOTE: The proper temperature for using the im-mobilizer key is from -40°F to 176°F (-40°Cto 80°C). If you heat the immobilizer keyover 176°F (80°C) to open the frozen lock,it may cause damage to the transponderin its head.
SC170E1-E Windscreen Washers and Wipers The windscreen washer bottle should be filled
with a solution of water and a proprietary winter screen wash additive. The windscreenwipers should not be used if the blades arefrozen to the windscreen or if they are cov-ered with snow, before this is removed.
ZC170B1-E
Electrical System
Winter conditions impose severe demandsupon vehicle electrical systems, particularlythe charging circuit. The battery condition andperformance along with the alternator perfor-mance and drive belt condition should bechecked 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 withsolution of the correct strength which shouldbe checked before the onset of winter andadjusted or changed as required. NOTE: The anti-freeze solution contains a corro-sion inhibitor to prevent degradation of thealuminum castings contained within theengine. Therefore, never, drain the systemand 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 andsubsequently bursting with the refrigerationsystem in use.

SC200B3-E TOWING ATTACHMENTS It is strongly recommended that only an Hyundai Approved towing attachment is usedto ensure that the loads placed upon the bodystructure are correctly distributed. The use ofa non approved attachment will result in theinvalidation of the vehicle warranty. Hyundaitowing attachments are designed and con-structed to ensure maximum towing perfor-mance and ease of fitment. A range of acces-sories including electrical kits are availablethrough the Hyundai dealer network. It is of the utmost importance that those areas of the vehicle which are subjected to greaterstress during towing are maintained in accor-dance with the recommendations given at theend of this book. In addition, the daily operatingchecks relating to engine oil, transmission oiland tyres must be performed at each refuellingto ensure maximum reliability and safety. The use of a proprietary stabiliser will assist in achieving an inherently stable outfit but whilstthe use of such equipment will improve thecharacteristics of a balanced outfit, it will notcompensate for a badly loaded and thereforeunstable outfit. The tyres and braking equipment fitted to the trailer or caravan must be maintained in ac-cordance with the recommendations of themanufacturer. Special attention should be paidto tyres which deteriorate through time and
WARNING:
It is not recommended that the vehicle be
used for towing until the first 1,000 milesof Running In has been completed. AllHyundai MATRIX models are suited to tow-ing trailers and caravans up to the limitsindicated below. MATRIX models fitted withautomatic transaxle have a transaxle oilcooler and further transaxle cooling shouldnot be required. C190E01FC-EAT
TRAILER AND CARAVAN TOWING

exposure rather than as a result of the dis- tances towed. The inside walls of the tyresshould be inspected along with the outsidewalls for cracking and damage. The trailerwheel nut torque must be checked on a regularbasis, preferably before each towing session.
The trailer hitch and the safety catch mecha-
nism must be maintained in good workingorder. The trailer break away cable or chainshould be inspected for damage and shouldbe attached to the vehicle towing attachmenteach and every time the trailer is hitched tothe vehicle.
Whilst towing, the performance of the vehicle
will be reduced in terms of acceleration, brak-ing and handling due to the increased loadsplaced upon the vehicle. The driver shouldanticipate the change in characteristics andadjust the driving style in keeping with thesechanges. Care should be exercised whencornering and braking to prevent the outfitbecoming uncontrollable by reducing corner-ing speeds and allowing increased brakingdistances.
The driver should exercise care to ensure that
when pulling away from rest particularly onuphill gradients the clutch unit is not subjectedto excessive slippage which will reduce theuseful life of this component. Use of the"Overdrive Off" "2" and "L" positions whendriving vehicles with automatic transmission

DRIVING YOUR HYUNDAI 2- 15
5. Always secure items in the trailer to pre-
vent load shift while driving.
6. Check the condition and air pressure of all tyres on the trailer and your car. Low tyre pressure can seriously affect the handling.Also check the spare tyre.
7. The vehicle/trailer combination is more af- fected by crosswind and buffeting. When being passed by a large vehicle, keep a constant speed and steer straightahead. If there is too much wind buffetingslow down to get out of the other vehicle'sair turbulence.
8. When parking your car and trailer, espe- cially on a hill, be sure to follow all thenormal precautions. Turn your front wheelinto the curb, set the parking brake firmly,and put the transaxle in 1st or Reverse(manual) or Park (automatic). In addition,place wheel chocks at each of the trailer'styres.
9. If the trailer has electric brakes, start your vehicle and trailer moving, and then applythe trailer brake controller by hand to besure the brakes are working. This lets youcheck your electrical connection at thesame time.
10.During your trip, check occasionally to be sure that the load is secure, and that thelights and any trailer brakes are still work-ing. 11.Avoid jerky starts, sudden acceleration or
sudden stops.
12.Avoid sharp turns and rapid lane changes.
13.Avoid holding the brake pedal down too long or too frequently. This could cause the brakes to overheat, resulting in re-duced braking efficiency.
14.When going down a hill, shift into a lower gear and use the engine braking effect. When ascending a long grade, downshift the transaxle to a lower gear and reducespeed to reduce chances of engine over-loading and/or overheating.
15.If you have to stop while going uphill, do not hold the vehicle in place by pressing onthe accelerator. This can cause the auto-matic transaxle to overheat. Use the park-ing brake or footbrake.
NOTE: When towing check transaxle fluid more frequently. CAUTION: If overheating should occur when towing,(temperature gauge reads near red zone),taking the following action may reduce oreliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. While in stop and go traffic, place the gear selection in park or neutral and idle the engine at a higher speed.

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
Type Size Inflation Pressure T115/70R(D)15420 kPa (60 psi)6. If the cause of the overheating cannot be
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.
