Dress for the car but also to pay attention to security issues. Whether in the car, what kind of dress, the bottom line is that there is a safe driver can not impede traffic or occupant safety car. Must not focus only ornamental, but ignored its practicality and safety, cause sometimes driving affect sight. Decorations should be neatly placed. China's "People's Republic of China on Road Traffic Safety Law" clearly provides that when the car hanging decorative pieces, can not affect the driver's line of sight.

    Car decoration should be comfortable as an indicator to prepare. Interior decoration colors and textures in line with the driver's aesthetic. Because only a comfortable working environment, make it possible to produce a driver feel comfortable, feel at ease. Make driving easier. Well, according to David stabilizer link understand car maintenance is easy to overlook some of the details:

    ●, doubt a manual gearbox oil (MT), automatic transmission fluid (AT), CVT oil (CVT) is the difference? Can mix it? Transmission oil lubrication effect, cooling and power transmission, it determines the type of the transmission structure of three main different ways they require lubrication, so that they need to determine the different properties of the transmission oil. Manual gearbox oil: oil is usually said manual transmission gear oil, but the role of lubrication. The American Petroleum Institute will be the vehicle by the use of performance gear oil into GL-1, GL-2, GL-3, GL-4, GL-5, GL-6 six. Which emphasis on overloaded GL-1, GL-2, GL-3 in the market have been eliminated, and as a general family cars are currently using GL-4, GL-5 (GL-6 is used by passenger ). From the oil characteristics, the most intuitive manual gearbox is automatic transmission fluid viscosity oil than the larger, replacement cycles are generally shorter than some of the automatic transmission fluid, most family cars in 4-6 ten thousand kilometers replace manual gearbox oil. AT gearbox oil: Automatic transmission oil is private, it has two functions, in addition to lubrication of the planetary gear set, heat, but more importantly as a power transmission, so it is not a manual transmission oil viscosity so "thick . " And its main role is to play a hydraulic transmission, so liquidity is very good, anti-bubble capacity requirements more stringent than the manual gearbox oil. Different types of automatic transmission fluid is added can not be mixed, as the flow rate of the different models of AT gearbox oil, density, dynamic and static friction performance, expansion coefficients are different. Some manufacturers are introduced to match the transmission oil according to the characteristics AT transmission, the proposed owner or replace or buy the appropriate model to be replaced in the 4S shop, do not replace other models themselves. CVT gearbox oil: CVT gearbox oil essence similar to AT oil, but it is also for oil, because the CVT gearbox is a trait of steel chain drive, you need to oil the parameters velocity, friction properties, expansion coefficient has the difference, so we can not use the AT gearbox oil instead. Relatively speaking, it should dilute AT automatic transmission fluid than some of the other but also with a certain damping friction drive chain to prevent slipping. About three main gearbox oil, and mix absolutely can not replace each other! Oil similar to AT and CVT gearbox oil gearbox oil also can not replace each other, if you really replace the use, although short little impact, but there is a long time for the effect of non-recovery of mechanical wear it. Like Ge uncle said: "BMW's front insert a standard Mercedes-Benz, it is probably inappropriate."

     ●, Question 2, why power steering oil is also used AT gearbox oil? Is wrong? Many attentive friends have this question: When you need to replace the power steering oil vehicle maintenance will find help on some brands of oil bottle is written in the automatic transmission fluid. Rest assured, 4S shop did not give the wrong things. Power steering oil and automatic transmission fluid are all above said hydraulic oil, thus can be common.

     ●, questions 3, why let the vehicle after changing the oil finished walking some distance and then check the oil level? After completion of the replacement engine oil dipstick need rough amount, so if this addition is complete, then left the car, you will find just added will appear in place of the oil deficit phenomenon. This is due to many voids in the static part between the fuel is not completely injecting new oil, such as in the various guide hole, so that after a complete oil change must be measured again after the engine is started, so that the oil corresponds to the full run The oil level inside. This usually occurs when a small amount of oil loss phenomenon, added again to the standard position. It is recommended to pay attention to this detail when the 4S shop maintenance.

     ● questions 4, only changing the oil filter is not shedding? Oil filter has two designs, one is to replace the whole, one is a separate filter replacement. Most models of the oil filter is replaced as a whole, but if you happen to be driving a vehicle designed to replace the filter alone, do not mistake it for maintenance personnel to cut corners on the replacement process. Such as Volkswagen, BMW, General Motors, PSA Peugeot Citroen's only part of the vehicle is designed to replace the filter.

     ● doubt 5, automobile replacement parts have warranty? Well, according to David stabilizer link was informed that there are tens of thousands of car parts, routine maintenance on the part needs to be replaced according to the intensity of use and the role of different, there are different warranty. Usually we say X years XX million km warranty vehicle warranty generally say is, the so-called vehicle warranty period is actually more accurate representation should be "the longest warranty period of the vehicle components," the warranty period, rather than All car parts warranty. In part because the car has a very different use of the material strength and theory of life is different, there are differences with the warranty period so-called vehicle warranty, such as power systems clutch pressure plate, pump; chassis parts rod joints, drive shaft, Warranty shock absorbers, car seats, door locks, and so these parts than the vehicle warranty period should be shorter. There is a class of consumable parts, such as light bulbs, glass, fuse and various oil-month warranty is only a few weeks or do not offer warranty. As each cycle models are not the same brand, so here is impossible to enumerate.

     ● doubt 6, almost the brakes changed, how thin it change? Brake system must be checked, but the wear of brake discs and brake pads are not as regular as routine maintenance items, in addition to the 4S shop offered free testing, but usually we need to observe its own brake system wear. Method 1: A new look at the thickness of the brake pad thickness of about 1.5cm, thickness with the use of continuous friction will gradually thinning. Professional and technical personnel suggest that when the thickness of the brake pads have been visually remaining original 1/3 the thickness (about 0.5cm) or so, the owner will increase the frequency of the self-test, ready to be replaced. Of course, individual models due to the wheel design reasons, do not have the conditions for the naked eye to see, need to remove the tire to complete Method 2: Listen to the sound if accompanied by "iron rub rail" hiss at tapping the brakes at the same time (there may be brake pads in effect produced when the run started installation), then the brake pads must be replaced immediately. Because the brake pads on both sides of the limit identity has direct friction brakes, brake pads have been proven over the limit. In this case, when replacing the brake pads at the same time to check with the brakes, the sound tends to happen brakes have been damaged, then even the replacement of the brake pads are still not eliminate the noise, serious brakes need to be replaced . Routine maintenance issues on the car, no harm to know more, if the 4S shop to allow customers into the shop, we might look at the process of maintenance staff, but also to a better understanding of their own car and avoid some of the details are not in place.
