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

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

2- 14 YC200E2-E Trailer or Vehicle Towing Tips
1. Before towing, check hitch and safety chain
connections as well as proper operation of the trailer running lights, brake lights, andturn signals.
2. Always drive your vehicle at a moderate speed (Less than 62 MPH)
3. Trailer towing requires more fuel than nor- mal conditions.
4. To maintain engine braking efficiency and electrical charging performance, do not usefifth gear (manual transaxle) or overdrive(automatic transaxle). Towing Bracket Attachment Location
NOTE:
o The total gross vehicle weight with trailer must not exceed the Gross Vehicle Weight Rating (GVWR) shown on thevehicle identification plate (see page 8-1). The total gross vehicle weight is thecombined weight of the vehicle, driver,all passengers and their luggage, cargo,hitch, trailer tongue load and other op-tional equipment.
o The front or rear axle weight must not exceed the Gross Axle Weight Rating(GAWR) shown on the vehicle identifi-cation plate (see page 8-1). it is possiblethat your towing package does not ex-ceed the GVWR but exceeds the GAWR.Improper trailer loading and/or too muchluggage in the trunk can overload therear axle. Redistribute the load andcheck the axle weight again. MANUAL

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.

CAUTION:
Personal injury and damage to the vehicle
may occur if jump starting is not per- formed correctly. If any doubt exists as tohow this operation should be performed,seek assistance from qualified personnel. WARNING:
Motor vehicle batteries contain sulphuric
acid and emit hydrogen gas. Protective clothing should be worn and care exer-cised to prevent the acid from coming intocontact with skin or clothing and the ve-hicle. Naked lights should not be permittedin the vicinity of the battery. Care shouldbe exercised to prevent sparks occurringduring connection. If acid accidentallycomes into contact with skin or eyes, theaffected area should immediately be flushed ponents such as the Fuel Injection system
computer and the Automatic Transaxlecomputer. The battery must never be dis-connected whilst the engine is running. SD040A2-E IF THE ENGINE OVERHEATS If the temperature gauge indicates overheat- ing:
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 condition-ing is on, turn it off.
3. If coolant is running out under the car or steam is coming out from under the bonnetstop the engine. Do not open the bonnetuntil the coolant has stopped running orthe steaming has stopped. If there is novisible loss of coolant and no steam, leavethe engine running and check to be surethe 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 missing. If it is not missing, check to see that it is tight. If the drive belt seems to besatisfactory, check for coolant leaking fromthe radiator, hoses or under the car. (If theair conditioning had been in use, it isnormal for cold water to be draining fromit).

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

Specified Scheduled Procedures The Specified scheduled procedures are listed
in the maintenance charts beginning at page 5-2. The operations specified must be per-formed at the time or mileage intervals shownirrespective of whether the mileage intervalhas been reached before the specified timeinterval.
Certain lubricants and components degrade
with both time and mileage (e.g. engine oil andbrake fluid) and therefore it is not permissableto base the maintenance schedule upon mile-age alone. It is strongly recommended thatthe maintenance operations are performed bythe factory-trained or distributor-trained tech-nicians at your Hyundai dealer because of the need for specialized knowledge and toolingand to ensure that no possibility of invalidatingthe manufacturers warranty exists.
The maintenance schedules relate to ve-
hicles operated under normal conditions, ve-hicles which are operated under adverseconditions will require more frequent mainte-nance which is described at page 5-5.
