2003 Hyundai Matrix engine overheat

WHAT TO DO IN AN EMERGENCY 3-3
WARNING: While the engine is running, keep hair, hands, and clothing away from moving 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 im- mediately and call the nearest Hyundai deal- er for assistance.
WARNING: Do not remove the radiator cap when the engine is hot. This can allow coolant to be blown out of the opening and cause serious burns. WARNING (Diesel only): Never work on injection system with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec- tors and high pressure pipes are subject to high pressure even after the engine stopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers should not move than 30cm closer to the ECU or wiring harness within the engine room while engine is running, since the high currents in the Common Rail system produce considerable magnetic fields. 2. The spare tire should only be used temporari-
ly and should be returned to the luggage compartment as soon as the original tire 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 tire is specifically designed for your car, it should not be used on any other vehicle.
5. The temporary spare tire should not be used
on any other wheels, nor should standard tires, snow tires, wheel covers or trim rings be used with the temporary spare wheel. If such use is attempted, damage to these items or other car components may occur.
6. The temporary spare tire pressure should be
checked once a month while the tire is stored.
CAUTION:
o Do not use snow chains with your tempo- rary spare tire.
o Do not use more than one temporary spare tire at a time.
D040A01FC-GAT TEMPORARY SPARE TIRE The following instructions for the temporary spare tire should be observed:
1. Check inflation pressure as soon as possible
after installing the spare tire, and adjust to the specified pressure. The tire pressure should be periodically checked and maintained at the specified pressure while the tire is stored.
Inflation Pressure
Tire Size
T115/70R(D)15 420 kPa (60 psi)
Spare Tire Pressure
6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has returned to normal. Then, if the engine cool- ant has been lost, carefully remove the radia- tor cap and add engine coolant to bring the fluid level in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur- ther signs of overheating. If overheating hap- pens again, call a Hyundai dealer for assis- tance.
CAUTION: Serious loss of engine coolant indicates there is a leak in the cooling system and this should be checked as soon as possible by a Hyundai dealer.

About the Catalytic Converter
Exhaust gases passing through the catalytic
converter cause it to operate at very high tem- peratures. As a result, the introduction of largeamounts of unburned gasoline may cause it tooverheat and create a fire hazard. This can beavoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good condition. Ex- tremely high converter temperatures can result from improper operation of the electri-cal, ignition or fuel injection systems.
o If your engine stalls, pings, knocks, or is hard to start, take your car to your Hyundaidealer as soon as possible and have thedifficulty corrected.
o Avoid driving with a very low fuel level. If your run out of gasoline, it could cause theengine to misfire and result in excessiveloading of the catalytic converter.
o Avoid idling the engine for periods longer than 10 minutes.
o Your Hyundai should not be either pushed or pulled to get it started. This can cause thecatalytic converter to overload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper,leaves or rags. As these materials couldcome in contact with the catalytic converterand could cause a fire. o Do not touch the catalytic converter or any
other part of the exhaust system while theengine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai dealer is your best source of assistance.

CONTROLS AND EQUIPMENT
1- 30 circuits becoming defective, approximately fifty per cent of the normal braking perfor-mance will be available.
If failure of one of the circuits occurs, the
required amount of pedal effort, pedal traveland stopping distance will be increased. Useof the gearbox is recommended to assist inbringing the vehicle to rest. The vehicle mustnot be driven once brake failure has occurreduntil the system has been repaired and isfunctioning normally.
The braking system employs a vacuum servo
in order that the pedal efforts are reduced.Power for the servo is derived from the engineand therefore, in the event of the enginestopping or the vehicle being towed, pedalefforts will be substantially increased.

PARKING BRAKE/BRAKE FLUID LEVEL WARNING LIGHT
WARNING: In the event of problems being suspected with the braking system, the advice of thenearest Hyundai dealer must be soughtbefore the vehicle is driven. Driving thevehicle with either an electrical or hydrau-lic braking system defect may be danger-ous, resulting in accident or personal in-jury. Warning light operation The parking brake/brake fluid level warning light will be illuminated whenever the ignitionswitch is turned to the "ON" position irrespec-tive of whether or not the parking brake isapplied and must be extinguished when theengine starts and the parking brake released. If the warning light fails to extinguish or illumi- nates at any other time, the vehicle must bebrought to rest in a safe location and the levelof brake fluid in the reservoir checked. If thefluid level is incorrect, fluid conforming to DOT3 or DOT 4 specifications should be added. If,after correcting the brake fluid level, the warn-ing light continues to be illuminated, the ad-vice of the nearest Hyundai dealer must besought before the vehicle is driven again.The Hyundai Matrix is equipped with a diago-nally split dual braking system which will en-sure that in the event of one of the brake
CAUTION: If the drive belt (generator belt) is loosen,
broken, or missing while the vehicle is driving, there may be a serious malfunc-tion, engine could overheat because thisbelt also drives the water pump.
SB210M1-E CHARGING SYSTEM WARNING LIGHT
The charging system warning light should
illuminate when the ignition switch is turned to the "ON" position and should be extinguishedwhen the engine is started. If the light fails toilluminate when the ignition is turned "ON" orfails to extinguish after starting the engine, thenearest Hyundai dealer should be contacted.If the light illuminates whilst the vehicle isbeing driven, stop the vehicle as soon as it issafe to do so and check the condition of thegenerator drive belt. If the belt is in place andthe tension is satisfactory, the advice of aHyundai dealer should be sought.

LOW FUEL LEVEL WARNING LIGHT
The low fuel warning light serves to warn the
driver that the remaining fuel quantity is ap- proximately 9 litres and that the vehicle shouldbe refuelled. If the vehicle is driven for anextended period with the low fuel warning lightilluminated there exists a possibility that mis-firing due to fuel shortage may occur. Thissituation must be avoided to prevent damageto the catalyst occurring.

The fuel gauge indicates the quantity of fuel remaining in the fuel tank. NOTE: The fuel gauge is not intended to giveother than an approximate indication ofthe fuel level and is unsuitable for thepurposes of calculating fuel consumptionfigures. SB215B1-E
ENGINE COOLANT TEMPERATURE GAUGE
The engine coolant temperature gauge indi-
cates the engine coolant temperature and will, under normal circumstances, give an indica-tion in the "Normal" or centre portion of thescale. Should the indication move into theupper or "Hot" portion of the scale, engineoverheating is indicated. Under these circum-stances, the vehicle should be brought to restas soon as is safe to do so and the engineturned off. Once the engine has cooled some-what, the coolant level and the condition ofthe generator/water pump drive belt should bechecked. If the cause of the overheating can-not be readily established, the assistance of aHyundai dealer should be sought.

WARNING: The engine cooling system is pressurized
and removal of the radiator cap when the engine is hot may cause hot water andsteam to be ejected from the radiator re-sulting in burns and scalding. The radiatorcap must only be removed when the en-gine has cooled. Do not add cold water toa hot engine to avoid the possibility ofengine damage. The use of plain water inthe cooling system is not recommendedsince the aluminium components of thecooling system require the use of a corro-sion inhibitor found in the recommendedEthylene Glycol type anti freeze solutions.

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.

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- 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.
