1- Check the engine oil level When measuring the level of the car engine oil level, the car must first be in a horizontal level, and the engine must be run until its normal operating temperature, and then the engine should be turned off by closing the contact switch and waiting for about five minutes, then the oil gauge is lifted from its place in the engine and cleaned well With a piece of cloth that does not contain lint, then put it in its place again in the engine, raise and note the oil level. Adjust the oil level in the engine.2- Tire pressure When measuring tire pressure, the tire must be cold, because measuring the pressure after a long drive in the car causes the friction between the tires of the car and the road to increase the temperature of the tires and thus increase the temperature of the air inside them, so its pressure rises, and then gives an incorrect reading of the pressure value inside the tires.3- Brake fluid (fluid)Failure to supply brake fluid (fluid) when its level is low in the brake fluid reservoir, because a low level of brake fluid indicates the wear of the brake lining and gives the opportunity for the brake indicator light to light up in the dashboard, but when supplying brake fluid, the lining wears out without giving any statement to the driver The brake light did not light up. Brake fluid is supplied only when it is leaking or when any of the internal parts of the cycle have been changed. Extreme caution must be exercised when using brake fluid because it has a severe effect on the paint of the car body.4- battery cable When changing or repairing any electrical parts of the car, he must begin by removing the negative battery cable from its place in order to avoid an electrical short-circuit in the car. Also, when the battery is changed, the negative cable must first be removed and then the wave cable. And before removing any of the battery cable, you must first make sure that the ignition switch (contact) is in the closed position, and that all light switches are closed, so as not to damage the semiconductor parts in the electronic circuits of the car. 5- Engine overheating When the engine temperature rises suddenly, you must immediately take the right lane of the road and stop the car in a safe place on the side of the road, and immediately close the ignition key (contact) to stop the engine from turning, then open the engine hood carefully and note the following :- The presence of any water leakage in the cooling cycle and work to prevent it or repair and change what is necessary, to ensure the safety of the cooling fan operation, and after the engine cools down, the radiator cap can be opened and to ensure that there is water inside, as well as to ensure the safety of the radiator water bladder and that it contains water until The required level, ensuring the integrity of the radiator cap, making sure that the radiator itself is safe and that there is nothing blocking the air from it. 6- Walking on the road Avoid walking on the road behind trucks loaded with (sand, bricks, asphalt, drums, or any lengths such as iron or wood skewers, etc.), as all of this is liable to fall at any moment suddenly in front of you on the road, leading to unimaginable accidents. Or at least, sand can fly on the windshield of the car, causing scratches or pits, damaging the glass, or bricks falling on the ground, damaging the engine oil cartridge.7- Change the spark plugs .Before changing the spark plugs of the car, it is necessary to blow around it well with compressed air to clean the dust that may have accumulated around it. It prevents dust from entering the engine cylinders and extends the life of the engine, and then you can install new spark plugs after making sure that the gap clearance is set to the recommended size. 8- Supplying radiator water when inspecting the radiator water, do not open the radiator cap while the engine is hot so that the pressure of the hot water does not rush to you and cause you burns. It is preferable to supply radiator water through the radiator bag up to the level of the upper mark in it, and note that the water level in the radiator bladder increases and decreases automatically depending on the condition of the engine, it increases while the engine is hot and decreases when the engine is cold, due to the increase in pressure and the imbalance that occurs in the radiator during heating and coldness; When filling the radiator through its neck hole while it is hot, it waits until it cools down a little and opens the cover slowly, then runs the engine during the water supply so that the new cold water mixes with the hot water around the cylinders, so there is no damage (curvature) in the cylinder head.9- Determine the brake sound When you hear a whistle sound when pressing the brake pedal, and you cannot determine the source of the sound, is it from the front brake? Or the background? Drive the car at a medium speed, then put the gearbox in the neutral position, and gradually raise the handbrake while driving. If the sound comes from the rear brake, and if not, it is from the front brake. 10- static electricity You may feel a slight electric shock when you get out of the car door and touch your hand to the body of the car, especially after a long driving period. Cotton fabrics and stay away from synthetic fibers clothing. This should also be taken into account in the driving seat. When you leave the driving seat, do not leave it suddenly, but slowly. Before getting up from the chair, try to hold in your hand any metal part of the car body to unload your static charge through it. 11- Petrol stations .Some petrol stations do not take into account the extreme accuracy in filtering the water from the petrol tanks, so when you accelerate the car and you hear the sound of (rail), which is similar to the fact that the electricity adjustment in the ignition circuit of the engine is not set (there is more electricity), especially if your car engine works with electronic injection. It does not need to adjust the ignition, because the ignition is adjusted electronically. This is evidence that you have filled your car’s gas tank from one of these stations, so do not deal with it again. 12- Lighting the battery lamp on the dashboard. When the battery light in the dashboard is lit with the contact open and remains lit even after the engine is running, this means that there is a defect in the charging circuit, either the battery is not receiving charging because of an internal defect in it, or the charging regulator has a defect, or the dynamo does not give the required voltage to charge The battery is due to an internal defect, or the dynamo belt is loose and not tight or cut, in this case you must stop the car and search for the cause of the defect, or deposit the car to the nearest car electrician. 13- The first engine warm-up period While the engine is running during the run-in period (for a new or over-the-top engine during the first period of operation (the first 1000 km), it is recommended that I do the following: Do not increase the engine speed at high speeds, avoid starting the engine quickly, and do not drive at high speed for a long time. Do not load the car with heavy loads, and do not tow any trailer during this period. 14- The color of the car engine oil .Some motorists rejoice and brag in front of their fellow drivers that their engine oil still does not change color after putting it in its engine and running the car for several kilometers. However, it does its job as it should, but if its color does not change after several kilometers, this is evidence that the used oil did not do its job and left sediments inside the engine. 15- The color of the car engine exhaust. In normal operating conditions, the exhaust gases are supposed to come out of the exhaust gases without color, but there are three types of exhaust gases that come out of the car’s exhaust in certain cases, each of which has a different color from the other, and through it the condition of the engine can be diagnosed: If the color of the exhaust is continuous white with Under normal operating conditions and in all conditions, this indicates that there is a leakage of cooling water into the combustion chamber and penetrates with it, and if the exhaust color is light gray tending to black, this is evidence of the combustion of a large amount of fuel in the combustion chamber, which indicates that the carburetor needs adjustment (adjustment fuel with air), and if the color of the exhaust is cyan, then this indicates that there is combustion of lubricating oil in the combustion chamber, which indicates that the engine needs repair. 16 – Raise the level of the car on the ground If you complain about the low level of the car on the ground, while ensuring the safety of the assistants and the springs, go immediately to one of the approved specialized centers and ask about the possibility of raising the level of the car off the ground, and do not take anyone’s advice to put attics on the springs from the bottom and from above, because they will really raise the level of the car. The car is off the ground, but it will damage the assistants, and cause roughness in the luggage while walking. 17- Smell petrol while driving .When there is a frequent complaint of smelling “raw” gasoline while driving. You must first make sure that there is no leakage of gasoline from the fuel cycle, then make sure that the engine is properly tuned, especially at high speeds, then there is no venting for the exhaust from the exhaust, then make sure that the interior vents of the rear trunk are well sealed, and finally make sure of good tightness when closing Cover the rear trunk of the car so that it does not leak the car’s exhaust into it. 18- Smell an unpleasant smell while driving .When you smell an unpleasant smell, especially while driving, or when the car engine is spinning, raise the car on a lift chute and look under the car along the length of the exhaust pipe. Usually, the reason is that part of the plastic bag is stuck to the high-temperature exhaust pipe, which burns on the pipe, melts and dries with The pipe is cold and the engine does not rotate, and it burns again with the engine running and the exhaust pipe is hot, and so on. So remove this part and clean its place well. 19- Battery status detection .The condition of the battery should not be detected by connecting the two ends of its poles with a cable or screwdriver, because this leads to the passage of a current of high ampere that damages the internal battery parts, and breaks the active substance in it from the plates. The right place to park the car. Beware of leaving your car in the wrong parking places, such as placing it under the direct light of the public street light poles, or placing it directly under the public electricity wires, or placing the car in the face of the direct thermal effect resulting from the factories, all of which have a negative effect on the car body paint. 20- Connect your car battery to an external battery If it is necessary to activate your car battery by giving it an initial charge through an external battery from another car via a connecting cable, then take into account that one end of the cable is connected to the positive terminal of your car battery (the battery is weak) first, then connects its other end to the positive pole of the external battery, and then connects one end of it The other cable is to the negative pole of the external battery, and the other end is to the negative terminal of your car battery, and this arrangement is very important to not damage the electronic units in the car.21- How to use the march to start the car.It is not permissible to insist on starting the engine of the car, when the starter is not able to do so, which leads to the rapid consumption of the battery without benefit. But run the march at intermittent intervals so that the running time of the march does not exceed (10 seconds) and then wait (30 seconds) between each period and the next until the march starts to start the car engine. 22- Manipulating the electrical connections of the car. In cars that contain electronic circuits, caution is taken when tampering with the electrical circuits, such as (installing a cassette, installing an alarm device, changing the battery, etc.) because any error in the electrical connections will damage the electronic units and will cost a lot. Any repairs or installations within authorized service centers. 23- Car air bag. In cars that have an air bag, when the warning lamp (SRS) in the dashboard lights up, this means that there is a defect or the car’s electrical connections have been tampered with, so you must immediately go to the nearest authorized service center to solve this problem, because any manipulation by anyone other than Aware of the theory of operating electronic sensors that causes the air bag to inflate in a sudden way, infecting the closest person to it. 24- Operating the windshield wipers. Do not operate front or rear windshield wipers without water in their water tank, because this can cause scratches on the glass surface and lead to blurring of vision, in addition to glass damage.25- high engine temperature. When the car engine temperature rises, while you are driving it, take the right side of the road, choose a safe place and stop the car, then stop the engine rotation immediately, and do not rush and raise the engine cover (the cap), or remove the radiator cap from its place, because high engine temperature means Boiling water in the cooling cycle, and high pressure also, causing water to rush from any outlet of the cycle severely, causing severe burns to anyone next to the car from the front.27 – Treat your car battery carefully Because it contains a very strong alkaline liquid (sulfuric acid), do not allow the liquid to come into contact with your eyes, skin, clothes, or the surface of the car body paint, because it has a caustic effect on these things, and the battery liquid scattered on those things must be washed immediately with a quantity A large amount of pure water, and a doctor should be consulted immediately if battery fluid splashes on the skin or eyes.28 – The battery wire (cable) must not be disconnected while the car key is in the “ON” position, otherwise the car’s electrical components, especially the electronic ones, may be damaged. Also, you should not short-circuit the battery (connecting its ends with a cable or metal part) because this causes the battery to overheat, causing damage to the internal battery components.29 – Avoid smoking near the battery, or near the flame of the fire, or light a cigarette near it, because this may lead to igniting the highly flammable gas generated from the battery, causing an explosion.30 – Train yourself to disassemble and install the wheels of your car using the car lift jack, before you really need to, as you do not expect help from others, especially if you are in remote areas away from urbanization.31 – When installing new tires for the wheels of your car, or when changing the wheels of the car according to the road followed in order to maintain the regularity of tire wear, make sure of the arrow mark on the surface of the tire, which shows the direction of rotation of the tire when moving forward. If the mark is found, then in this case the front right tire must be replaced with the right rear tire, as well as the front from the left side with the rear from the left side. This is to maintain the direction of rotation of the tire according to the manufacturer’s instructions. 32 – Do not try to adjust the rearview mirrors while driving, because this can lead to distracting your eyes from the road ahead, causing dangers because the accident happens in seconds. It is always preferable to adjust the interior and exterior mirrors from the moment you sit on the seat and before you start driving.33 – Note that cars are now equipped with convex mirrors that show the picture in an unreal position, that is, they are smaller and farther than they were originally, compared to the flat mirrors used in homes, so caution must be taken when making maneuvers on the road and changing the direction of traffic . 34 – Care must be taken when using the floor pedals in the car. As it must be suitable for the area of the floor used in it, because if it was longer, it would hinder the movement of the pedal (gasoline, brake or clutch – and cause their journey to not complete to the end, and thus the driver’s complaint about not towing the car may increase, Or poor braking, or difficulty engaging the clutch. 35 – Do not leave your car engine in a state of rotation (running) for a long time while the car is in a closed or poorly ventilated place, because this would lead to suffocation and death, as the exhaust gases resulting from combustion contain odorless, toxic carbon monoxide. .36 – Avoid driving while the trunk of the car is open or not tightly closed, because that would pass exhaust gases that contain toxic carbon monoxide into the cockpit, cause loss of consciousness, and lead to death because it is odorless.37 – Before you start driving your car, make sure that the hood is tightly closed, as failure to close it leads to its opening automatically while driving on the road and suddenly, which causes a great danger of blocking the vision in front of the driver, in addition to the possibility of breaking the windshield of the car. and lead to serious accidents.38 – When opening the cap of the gasoline tank, the cap must be opened gradually and slowly to give an opportunity for the steam formed inside the fuel tank to leak into the atmosphere gradually, and not all at once. While opening the lid and hearing a sound similar to (hiss), then I wait a little while and do not continue opening the lid until that sound is completely stopped, then I start to complete opening the lid, and the reason for this is that the fuel vapor may rush out strongly as a result of the high pressure of gasoline vapor inside The fuel tank drops from atmospheric pressure, causing serious injuries.39 – In cars equipped with a catalytic converter in the exhaust system, to maintain it, always try to have the fuel level in the tank (tank) higher than a quarter, because a fuel level lower than a quarter may damage the catalytic converter.40 – Note that the oil indicator light on the dashboard (red) when lit after the engine is spinning, means that the oil pressure in the engine is weak, and that there is a defect in the oil cycle inside the engine, but the dimension is believed to indicate the oil level in the engine, but which refers to Engine Oil Level The level gauge in your engine. This lamp is supposed to be lit during the opening of the connect, and at the start of the engine, but it must be extinguished immediately as soon as the engine is running. If everything is in order, then the car must be towed to the nearest specialized service center for examination, examination and finding out the reason.41 – When installing new tires for the wheels of your car, note carefully on the surface of the tire, there may be a sign that is an arrow indicating the direction of the tire installation in the direction of the rotation of the car wheel while traveling on the road, as the tire manufacturer placed this arrow according to the type (tread) of the tire pattern And the difference in the installation opposite the arrow shown may help the rapid wear of the tire, in addition to the feeling of tremors in the car body while driving.42 – When you need to lift your car on the car lift chock, you should be careful not to put the jack in areas under the car that are not intended for lifting, which the car manufacturer directs you to, so as not to damage the car’s underlying parts, or you may puncture the car body with the jack by mistake. And please generally put the cranks in the places where the car factory indicates.43 – When your car breaks down for some reason, and you have towed it by another car, the following should be taken into account: – In order to avoid the entry of exhaust gases from the tractor car into your car while you are in it, close the external ventilation gate, by setting the lever (or switch) to select the air source inside your car to Mode (air circulation inside the passenger compartment).In order not to damage the pump of the driving auxiliary device, i.e. (power steering pump), you must make sure that there is power fluid (oil) in the pump safe, because its absence may cause damage to the pump. Also, take into account the presence of oil in the automatic transmission box so as not to damage its internal groups .It is also taken into account that the gearbox stick is in the non-interlocking position (N). If the car is four-wheel drive, the auxiliary gear stick is placed in the i-shift position in the (2H) position .It is best in all these cases to tow the entire car on its four wheels on a towing truck.44 – Do not try to start the car engine by pushing it or towing it when the battery is weak, because this poses a great danger to the mechanical and electrical groups in the car, especially cars equipped with an automatic gearbox, as they did not start the movement in this way because the structure of these cars differs from cars equipped with a manual transmission box .45 – The car ignition key should not be removed from its place while driving, because this would lead to: First: For cars equipped with a power steering device, POWER STEERING, as this will stop the power device from working, which will weaken the loss of steering control in the car. Second: As for the mechanical brake servo system (servo), it will stop working, which will lead to a decrease in the efficiency of the brakes, and it will require a great effort to apply the brakes.46 – The fuel tank filler cap may have the phrase UNLEADED FUEL ONLY, which means “unleaded fuel only.” It is found in cars that run on unleaded gasoline. If you fill in with leaded gasoline in these cars, the catalytic converter may be damaged. And your engine will suffer severe damage. I warn you about that… 47 – Avoid turning the car engine start switch in the “START” position while the engine is running, because this will damage the starter motor (the marcher), and the flywheel (the Volan ) will be damaged. 48 – The car key should not be left in the “ON” position for a long time, especially when the engine is not running, because this will drain the battery charge and damage it. 49 – Do not leave the car lights on for a long period of time unnecessarily while the car engine is stopped, because this would discharge the battery charge and lead to damage, and therefore it will be difficult to start the management process, or this will lead to the inability to start the engine.50 – Always keep the spare tire of the car wheels, which is in the rear car bag, to be in good condition, and a standard inflation, so that it is ready for emergency use at any time.51 – Be careful not to put oil or any grease on the bolts or nuts of the wheels when loosening and re-tightening them, because this leads to excessive tension, which will make them lose their durability.52 – Be careful not to tighten (tighten) the wheel nuts when tightening them with excessive force by using the foot pressure on the wrench of the wheel nuts, or by using a (lavia) tube to strengthen the tightening torque, because this can lead to the nuts and bolts being tightened more than the required limit and lose their flexibility.53 – When lifting the car on the lift jack to change one of the punctured tires, the spare tire should be placed under the car body close to the jack, because this reduces the risk in the event of the jack slipping out of its position. It also takes into account the placement of a bracket at the wheels in anticipation of moving the car when it is raised on the lift bridge.
