2006 Hyundai Matrix engine overheat

3 WHAT TO DO IN AN EMERGENCY
4IF THE ENGINE OVERHEATS
D030A02A-AAT If your temperature gauge indicates overheating, you experience a loss of power, or hear loud pinging or knock- ing, the engine is probably too hot. Ifthis happens to you, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the gear selector lever in "P"
(automatic) or neutral (manual transaxle) and set the parking brake. If the air conditioning is on, turn it off.
3. If engine coolant is running out un- der the car or steam is coming outfrom the hood, stop the engine. Donot open the hood until the engine coolant has stopped running or the steaming has stopped. If there is novisible loss of engine coolant and no steam, leave the engine running and check to be sure the enginecooling 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 be satisfactory,
3. Attach the clamps of the jumper
cable in the exact location shown.First, attach one clamp of the jumper cable to the positive (+) post or cable of the discharged battery. Thenattach the other end of the same cable to the positive (+) post or cable of the booster battery. Next,using the other cable, attach one clamp to the negative (-) post or cable of the booster battery. Thenattach the other end of that cable to a solid metal part of the engine away from the battery. Do not con-nect the cable to any moving part.
4. Start the engine in the car with the
booster battery and let it run for afew minutes. This will help to as- sure that the booster battery is fully charged. During the jumping opera-tion, run the engine in this vehicle at about 2,000 rpm.
5. Start the engine in the car with the discharged battery using the nor-mal starting procedure. After the engine starts, leave the jumpercables connected and let the engine run at fast idle or about 2,000 rpm for several minutes. 6. Carefully remove the jumper cables
in the reverse order of attachment.
If you do not know why your batterybecame discharged (because the lightswere left on, etc.), have the charging system checked by your Hyundai dealer.

check for coolant leaking from the radiator, hoses or under the car. (Ifthe air conditioning had been in use, it is normal for cold water to be draining from it when you stop).
WARNING (Diesel only):
Never work on injection system with engine running or within 30 sec- onds after shutting off engine. Highpressure pump, rail, injectors and high pressure pipes are subject to high pressure even after the enginestopped. The fuel jet produced by fuel leaks may cause serious in- jury, if it touch the body. Peopleusing pacemakers should not move than 30cm closer to the ECU or wiring harness within the engine 5. If the water pump drive belt is bro-
ken or coolant is leaking out, stopthe engine immediately and call the nearest Hyundai dealer for assis- tance. CAUTION:
Serious loss of engine coolant indi- cates there is a leak in the cooling system and this should be checkedas soon as possible by a Hyundai dealer.
room while engine is running, since the high currents in the CommonRail system produce considerable magnetic fields.
6. If you cannot find the cause of the
overheating, wait until the engine temperature has returned to nor- mal. Then, if the engine coolant hasbeen lost, carefully add coolant to the reservoir (page 6-14) to bring the fluid level in the reservoir up tothe halfway mark.
WARNING:
While the engine is running, keephair, hands, and clothing away from moving parts such as the fan and drive belts to prevent injury.
WARNING:
Do not remove the radiator cap whenthe engine is hot. This can allowcoolant to be blown out of the open- ing and cause serious burns. 7. Proceed with caution, keeping alert
for further signs of overheating. If overheating happens again, call a Hyundai dealer for assistance.

EMISSION CONTROL SYSTEMS
3CATALYTIC CONVERTER
H020A01A-GAT
(If Installed) ; For a gasoline engine
HFC505
The catalytic converter is part of the
exhaust emission control system. Its purpose is to remove certain engine emission products from the engine'sexhaust. It looks something like a muffler and is located underneath the car in the exhaust system.
Catalytic Converter H020B01A-GAT
About the Catalytic Converter
Exhaust gases passing through the
catalytic converter cause it to operate at very high temperatures. As a re- sult, the introduction of large amounts of unburned gasoline may cause it tooverheat and create a fire hazard. This can be avoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good con- dition. Extremely high converter temperatures can result from im-proper operation of the electrical, ignition or fuel injection systems. o If your engine stalls, pings, knocks,
or is hard to start, take your car to your Hyundai dealer as soon as possible and have the difficulty corrected.
o Avoid driving with a very low fuel level. If your run out of gasoline, itcould cause the engine to misfireand result in excessive loading 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 the catalytic con- verter to overload.
o Take care not to stop your Hyundai
over any combustible material suchas grass, paper, leaves or rags. As these materials could come in con- tact with the catalytic converter andcould cause a fire.
o Do not touch the catalytic con-
verter or any other part of the ex-haust system while the engine is running as it is very hot and could result in burns.
o Remember that your Hyundai
dealer is your best source of assis-tance.
H020D01S-GAT
; For a diesel engine
All Hyundai vehicles are equipped
with oxidation type catalytic converter to reduce the carbon monoxide, hy- drocarbons and particulate containedin the exhaust gas.

SB215A1-E FUEL GAUGE The fuel gauge indicates the quantity of fuel remaining in the fuel tank. NOTE: The fuel gauge is not intended to give other than an approximate indi- cation of the fuel level and is unsuit- able for the purposes of calculatingfuel consumption figures.
SB210S1-E BRAKE PAD WEAR INDICATOR The front brake disc pads are fitted with an audible wear indicator which will cause a high pitched noise to be emit-ted when the remaining amount of fric- tion lining is below the specified value. When the wear indicator is heard, thebrake pads should be replaced without delay to avoid damage occurring to the brake discs and a severe reduction inbraking efficiency. B950A01E-EAT REAR FOG AUDIBLE WARNING SOUND The rear fog audible warning chime sounds when the rear fog lights are onand the door in driver side is open.
The engine coolant temperature gaugeindicates the engine coolant tempera-ture and will, under normal circum- stances, give an indication in the "Nor- mal" or centre portion of the scale.Should the indication move into the
upper or "HOT" portion of the scale, engine overheating is indicated. Underthese circumstances, the vehicle should be brought to rest as soon as is safe to do so and the engine turned off. Oncethe engine has cooled somewhat, the coolant level and the condition of the generator/water pump drive belt shouldbe checked.

If the cause of the overheating cannot be readily established, the assistanceof a Hyundai authorised repairer should be sought.
!WARNING:
The engine cooling system is pres- surized and removal of the radiatorcap when the engine is hot may cause hot water and steam to be ejected from the radiator resulting inburns and scalding. The radiator cap must only be removed when the en- gine has cooled. Do not add coldwater to a hot engine to avoid the possibility of engine damage. The use of plain water in the coolingsystem is not recommended since the aluminium components of the cooling system require the use of acorrosion inhibitor found in the rec- ommended Ethylene Glycol type anti freeze solutions.

The speedometer indicates the vehicle speed in both miles and kilometres per hour.
The tachometer registers the speed of the engine in revolutions per minute(R.P.M.).

2 DRIVING YOUR HYUNDAI

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 5. If youdrive your car in severe conditions, more frequent maintenance is re- quired (see Section 5 for details).
o Keep your car clean. For maximum service, your car should be keptclean and free of corrosive materi-als. It is especially important that mud, dirt, ice, etc. not be allowed to accumulate on the underside of thecar. This extra weight can result in increased fuel consumption and also contribute to corrosion.
o Travel lightly. Don't carry unneces- sary weight in your car. Weight is anenemy of good fuel economy.
o Don't let the engine idle longer than necessary. If you are waiting (andnot in traffic), turn off your engine andrestart only when you're ready to go.
SC150A1-F You can save fuel and get more miles from your car if you follow these sug-gestions:
o Drive smoothly. Accelerate at a
moderate rate. Don't make "jack- rabbit" starts or full-throttle shifts and maintain a steady cruising speed. Don't race between stoplights. Try toadjust your speed to that of the other traffic so you don't have to change speeds unnecessarily.Avoid heavy traffic whenever pos- sible. Always maintain a safe dis- tance from other vehicles so you canavoid unnecessary braking. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel your caruses. Driving at a moderate speed, especially on the highway, is one ofthe most effective ways to reduce fuel consumption.
DRIVING FOR ECONOMY
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 tyres. Keep them
inflated to the recommended pres-sure. Incorrect infla-tion, either too much or too little, results in unneces- sary tyre wear. Check the tyre 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 tyre wearand may also result in other prob- lems as well as greater fuel con- sumption.
