  1. 1. USER MANUAL work presented by JESUS Murillo Durango Oscar David García Jhomer Londoño Marínteacher : Mauricio Martinez
  2. 2. SECURITY AND COMFORT AIRBAG SAFETY SYSTEMAREknown plenty of advantages utilization ta repor belt.Provides a means for fixing to seat firmly and surely avoided, in case of frontal collision orside, the driver and passengers to fly because of the inertiacaused on impact. This system prevents displacement of the chest and waist of theoccupantseat, however, does not prevent the head to become displaced to both achieve thesteering wheel. In the case of a frontal impact against a stationary object traveling at aspeed over 25-30km / h, there is a significant risk of serious injuryhead, neck and upper torso of the seat occupant. To reduce the consequencesThis type of accident has ado Unique Designs Airbag system. Basically, the airbag (whichtranslated means "air bag") is constituted by an inflatable cushion, placed inside thedriving, and capable of fully deployed in the event of impact, providing the occupantan area of the vehicle on which it can absorb its displacement as a result of thecollision. This system reduces by more than 50% the risk of injury fromaccident while reducing their severity if q ue even happen.IMPACT 1.DIAGRAMAWhen a car has a frontal collision at more than 30 km / h, all that happens within theswelling takes place in a very short time interval of about 120 milliseconds,that is, what it took to blink. In this time interval the body of occupantsvehicle is in a violent and uncontrolled movement to the front to be
  3. 3. cushioned by airbags and seatbelts. In the next figures uientesobserve the typical sequence of an accident (speed 56 km / h).Here we see the exact moment of the collision (time 0). Neither occupant of the vehicle or the Airbag have moved. From this moment begins the whole process. Between 5 and 20 ms after impact, depending Airbag system employed, the detonator of the drivers air bag is activated by the system control unit and the blast gas occurs generates enough that the air sa bowl begins to expand. in the If the vehicle has Passenger airbag, it will normally be activated simultaneously to the driver, although the latter depends on whether one or two leads Airbag detonators. If it takes two detonators, the second comes up with a few thousandths of too late to prevent violence in the explosion and better control the spread of Inflatable cushion.
  4. 4. After about 30 to 50 ms of the air cushion is fully inflated pending receiving the impact of the drivers body. INSTRUMENTS AND CONTROLS Indicator engine temperaturathe vehicle should not exceed 90 degree heat and activate the fan should drop 20 degrees
  5. 5. This indicator is essentially a thermometer and is present in every car with an engine cooling system and liquid cooling in some air. It is common for a needle indicator with scale graduated in degrees and in whose area have drawn three colored zones, the first (yellow), even working for the engine cold, thesecond (green). area representing optimal working temperature, and the third (red) to the area of the motor overheats. In some cases the type used digital screens, with temperature indicator or keywords. Actually what is measured is the temperature of the engine coolant in the cylinder head and close to the last cylinder, here is where the refrigerant has reached its highesttemperature has cooled because all cylinders. For this reason there is placed a sensor thatsends a signal indicator electrical panel which is registered by the needle as a temperature value. Almost all temperature measurement systems of automobiles today use as a thermistor sensor, and as an indicator, an instrument for measuring the resistance value of the thermistor with the graduated scale in degrees.
  6. 6. As the car is constantly subjected to accelerations and decelerations, lateral forces during cornering and vertical oscillatory movement with road irregularities, the indicator should have a mechanism of movement of the test needle to these disturbances, such as biindicator sheet galvanometer-metal frame or cross, so that this constant movement of the car is not transmitted to the pointer, and thus show a steady reading INSTRUCTIONS AND OPERATING COOLING SYSTEM OPERATION The cooling system is a system composed of parts and refrigerant that work together tocontrol the operating temperature of the engine and optimum performance. The systemhas conduits inside the monoblock and engine head, and a pump that drives the band to circulate the refrigerant, a thermostat to control the temperature of the refrigerant, aradiator for cooling the refrigerant, a radiator for maintaining stopper the pressure in the system and hoses for conducting coolant to the engine radiator. The liquid flowing through the system, antifreeze or commonly referred to as a refrigerant, supports extreme heat and cold, contains corrosion inhibitors and lubricants to keep the system in optimal working condition. The refrigerant starts its movement in the water pump. The impeller of the water pump uses centrifugal force to circulate coolant radiator and propel the engine block. The pumps are usually driven by the timing belt or timing chain. Now a days, there are evenelectrically driven pumps. If the water pump experiences a seal leakage, a broken body, abroken impeller or bearing malfunction, this will affect the entire cooling system causing the vehicle to over-heat. While the refrigerant flows through the system absorbs heat from the motor before reaching the thermostat. The valve is a thermostat which measures refrigerant temperature and opened to allow the hot fluid to the radiator trip. If the thermostat is sticky or goes down, it affects the entire cooling system.
  7. 7. Once that is released by the thermostat, the hot refrigerant travels within a hose to be cooled in the radiator. The refrigerant passes through thin tubes in the radiator andcooled by the outside air passing through the tubes. Depending on vehicle speed, air flow is provided during the shooting by the movement thereof (inlet air) and / or fans. Restrictions on the radiator may compromise their ability to reduce the temperature. These restrictions may be external or the internal air flow in the refrigerant flow restriction. A malfunction of the electric motor of the fan or fan clutch may restrict airflow through the radiator. Check / replace the fan clutch ... the expected useful life of the water pump and fan clutch are about the same and share the same arrow. A failed fan clutch that can cause severe damage to the water pump. While the coolant temperature increases, the pressure also increases in the coolingsystem. This pressure is regulated by the radiator cap. It requires a correct pressure in the system to ensure proper lubrication of the seal. The refrigerant boiling point increases with increasing pressure in the cooling system. For each pound per square inch is increased cooling system pressure, the boiling point increases 3 ° F. If the pressure increases above a specific point, a valve with a compressed spring open and release the pressure. If the engine is over-heated, radiator cap and thermostat must be replaced. It is important to regularly inspect the condition of the belts and hoses of your cooling system. Hoses softened, bands that had been contaminated with oil, belts or hosesfractured may cause malfunctions in the entire cooling system. It is also very important to the proper tension of the belt. Always refer to the manufacturers manual to determine the type of coolant for yourvehicle. This and the proper mixture of coolant and distilled water are life to maintain the cooling system properly. Most parts stores offer a premixed solution and distilled water coolant. While this may seem like an unnecessary additional expense, with time, the cleanliness of a premixed solution compensate for the amount paid.
  8. 8. Mineral deposits and sediments corroded parts accumulate in the cooling system. Beforemaking repairs to the cooling system, it is important to drain and clean the system prior to the installation of new parts. This job is much easier if you use the drain-filling game. Failure to clean the contaminated system previously installed the new parts and may generate premature failure of components. DIAGRAM

The basic inspection is carried out to a maximum of 24,000 km(15,000 miles) or 4 months, whichever comes first. All checkpoints must be carried out averification operation or condition.All defects are noted on the inspection form for subsequent correction, if ordered by theowner the vehicle. Note! The standard time for repair Preventive Maintenance BasicService is based on inspection and change oil and filter without any repair or adjustment.SECURITY COUNCILRead and understand the precautions and guidelines in the Service Information, Groups 1-9, "Practices General Safety Precautions "before performing any of these procedures. Askyour supervisor to enable them, if not properly trained and certified in any theseprocedures.Never operate a diesel engine in an area where submit hydrocarbon emissions (gasolinefor example) or is suspected that its presence there. Hydrocarbon fumes can enter to theair intake and the engine do sobrerevolucione, causing severe damage and / or explosionor fire. It may be a serious personal injury or death.
  11. 11. before working on a vehicle, set the parking brake hand, put the transmission in neutraland block wheels. Failure to do so may result in the unexpected vehicle movement andcan serial cause personal injury or deathWhen entering or leaving the cab, beware. Cójase always tight and / or stand stablybefore transferring the weight to that position. No charge nothing when entering orleaving. Make sure the soles of his shoes and steps have no cabin dirt, grease, oil ormoisture before using steps. Failure to do so may result a fall may occur serious personalinjury or death.Clean up fuel spills immediately. The fuel that leaks or spills on surfaces hot or electricalcomponents can cause fire with the potential for serious injury personnel.Serious burns can result from contact with Shaft hot oil, engine or transmission.
