1: running-in period of new car
The new car has just left the factory, and all parts of the car have not been run-in, so it must be used with caution. If you drive too fast, it will lead to accelerated wear of parts and shorten the service life of the car, so you must slow down and let the car adapt to the road first.
2. Clean the interior of the new car
Create a good interior environment to protect health: carpets, seats, air conditioning outlets, suitcases and other places in automobile interiors are often exposed to humid air or water stains. In a certain environment, these places are most likely to breed bacteria, make the room moldy and smell, which not only affects the indoor air environment, but also poses a threat to health.
Clean control room: dashboard and steering wheel are mostly made of plastic and leather, which is easy to attach dust, but also convenient to clean. It must be noted that since the instrument is exposed to the sun for a long time, it is easy to age and become brittle, so it is best to choose good quality surface wax for spraying and then wipe it with clean cotton cloth, which can protect the instrument table well.
Clean the air conditioning pipes. Remove the air outlet of the air conditioner, insert the thin tube of air conditioner cleaning agent into the air duct, and spray an appropriate amount of air conditioner cleaning agent. Then close the air outlet of the air conditioner, open the internal circulation of the air conditioner, start the engine, and run at idle speed for about 10 minutes. At the same time, clean the air conditioner filter.
Vacuum the things in the car: clean and remove the dust in the car, sweep away the big dirt, and then vacuum the dust in the gap between the carpet and the chair.
3. First maintenance of new car
At present, there are two or three comparison standards for popular maintenance rules in the market, such as mileage, maintenance interval and engine working time. Generally, car dealers require first come, then come. But what if you use less cars at ordinary times? Experts suggest that people who use fewer cars should maintain them at least once every six months.
Now many car owners usually use less cars, and some only drive 1000 kilometers a year. Car owners are advised to maintain it at least once every six months. On the one hand, oil will deteriorate if used for a long time. In addition, the driving speed in urban areas is mostly slow, and the mileage seems to be small, but in fact the workload of the engine is not small. Therefore, the owner may wish to take advantage of the opportunity of free inspection by the manufacturer to maintain the car, keep the car in good condition and reduce the later maintenance costs.
Maintain taboos
First, avoid running the engine for a long time in an unventilated garage. The exhaust gas from the engine contains carbon monoxide, which is an invisible and odorless poisonous gas. Long-term exposure to low-concentration carbon monoxide gas will cause headache, shortness of breath, nausea and vomiting, physical weakness and dizziness, psychological confusion and even brain damage. If you start the engine in the garage, you should open the garage door or open the exhaust device, so as to discharge the exhaust gas from the garage at any time. Don't stay near the exhaust pipe of the working engine for a long time, even if you work in the open air.
Second, avoid sucking the tubing with your mouth. Gasoline is not only flammable and explosive, but also toxic. Especially leaded gasoline, will damage people's nervous system, digestive tract and kidneys. In addition, gasoline also contains high concentration of sulfide, because hydrogen sulfide is also toxic, if inhaled gasoline, it will lead to poisoning or death. In case of inhalation, force yourself to vomit and go to the hospital for treatment in time.
Third, avoid contact with carburetor cleaner. Carburetor cleaning agents mostly contain methyl chloride, aromatic hydrocarbons and ethanol, which are toxic to some extent, so it is very dangerous for these substances to be inhaled into the nose or splashed on the skin and eyes.
Fourth, avoid mechanical injury. The maintenance of a car is related to all aspects. During maintenance operations, obvious operation signs should be set to prevent others from being injured due to misoperation. When starting a car, pay attention to the gear of the transmission to prevent misoperation and personal injury. When working under the hood, others should be allowed to leave the cab to prevent the engine from suddenly turning or others operating the mechanism, resulting in accidental injuries. If you need to work under the car, you should set up obvious signs and cover the car with wood. When a car is supported by a jack, the jack should be placed stably. Prepare driving tools before driving, and do not use fragile items such as bricks. Do not test screw holes, lock holes, etc. when installing components. Avoid breaking your fingers with your hands. Don't work under the car when testing the engine.
How to maintain the car?
1. Turn on the switch before starting the car, and it cannot be started directly. When the switch is turned on, the vehicle will generally have a self-test. All the indicator lights will light up together, and then go out one by one after the self-test is completed. Only after the whole process is completed can it be started. It usually takes about 3 seconds.
2. Brake pads should be inspected regularly. The front brake pads should be inspected at 30,000 kilometers, and the rear brake pads should be inspected at about 60,000 kilometers. If it wears quickly, it should be replaced in time.
3. The tires should be replaced at 30,000 kilometers, with the front wheel turning to the rear wheel and the rear wheel turning, which can prolong the service life of the tires.
4. When the cold car starts, pay attention to let the car idle for one and a half minutes to give the car a warm-up time.
It is very important to go to a professional 4S shop for maintenance within the specified time. Generally, it is 5000 km in Bao Xiao, Dabao 10000, and then it will be repeated every 5000 km.
6. After parking, it is necessary to extend the flameout for half a minute. Strong detergency, no irritation to human skin, and more practical for dermal parts.
Remove scratches with toothpaste
Shiny car paint often inadvertently shows scratches. For this reason, it is not cost-effective for the owner to push the sand wax to the car beauty shop. Using toothpaste grinding method to remove minor scratches has a good effect. Rinse the scratch with clear water first, then take a clean cloth or towel and dip a little toothpaste in it and rub it gently and repeatedly. After the scratches disappear or weaken, dry them with a wet towel. There is a simple reason. Toothpaste itself is an abrasive for cleaning teeth, which has no harm to human body or car paint.
3. Remove the sticker with essential balm.
It is extremely difficult to remove all kinds of certificates posted on the windshield of the car during the annual review. Apply wind oil essence on the back of the self-adhesive sticker, and wipe it with a dry cloth after a while, and it will fall off without leaving any traces. This law is applicable to self-adhesive trademarks affixed to various commodities. The reason is that essential balm can dissolve the effective components of the adhesive. If you don't have essential balm, you can use toothpaste instead, but the effect is slightly worse.
4. talcum powder can dissolve the adhesion of door seal.
After the rain, the door sealing strip was wet, the paint surface adhered, and the door was uneven, making a "squeaking" sound. You can put a handful of talcum powder on the rubber seam of the car door, and the symptoms will disappear. You can open and close it freely without any noise.
2 How to maintain the car in rainy days
1, should be cleaned up in time.
Some car owners think it is unnecessary to wash their cars in rainy days, but it is not. In case of heavy rain, the car should be cleaned in time, otherwise the gap between the front and rear tires of the car is easy to accumulate mud and moisture is hidden inside, and the car body will rust. In order to prevent the acidic substances in the rain from damaging the car body, the simplest and most effective method is that the owner can prepare a dry cloth, simply wipe the car body, and then go to the repair shop or 4S shop to wax and polish the car once the weather clears up.
2. It is fragile to cover the car clothes in rainy days.
In addition, many car owners are accustomed to putting clothes on their vehicles, although this can prevent the surface of the vehicles from being damaged. However, in windy and rainy weather, clothes will repeatedly whip the car paint, especially when sand blows into the clothes, which will draw tiny scratches on the car body and cause the paint surface to turn black over time.
3. Any scratches should be repaired immediately.
In addition, if there are scratches on the surface of the car, rust will occur in wet weather after the protective layer of the car paint falls off. Therefore, if there are paint peeling or deep scratches on the car body, it should be repaired immediately, and the drainage holes of the door and the bottom of the car body should be inspected and cleaned frequently.
4. Check whether the brake fluid is wet.
The wet weather in rainy season will cause a lot of water to enter the brake fluid on the brake fluid cup. If water enters the brake fluid, the high temperature generated during vehicle braking will evaporate a lot of water vapor, and the compressibility of gas will cause braking failure or even failure.
1. Suggestions on the use of air conditioners
Before turning on the air conditioner, turn on the external circulation of the air conditioner to exhaust the hot air.
The temperature inside the car is often very high in summer, so don't turn on the air conditioner as soon as you get on the bus. Open the doors and windows to breathe for three to five minutes, and then turn on the air conditioner after the hot air disappears, which not only has a better cooling effect, but also protects the vehicle. If the engine is under heavy load for a long time, the air conditioner should be temporarily turned off. When cooling, the wind direction of the air conditioner can be upward, which is better, because the cold air sinks. Turning off the air conditioner before reaching the destination can not only reduce the odor, but also prolong the life of the air conditioner.
2. Compressor and condenser
After the refrigeration system stops, the compressor can work for more than 10 minutes every two weeks if conditions permit. It is best to check the belt tension of the compressor regularly. If the refrigerator oil leaks, it should be handled in time; Get into the habit of cleaning the condenser frequently to reduce the stains on the condenser radiator.
3. Tire and tire pressure
Check the tires regularly in summer, and replace them with new ones if they are seriously worn. When it is hot in summer, the tire pressure will be higher, which is easy to cause a puncture accident and cause injury. In hot weather, speeding, overloading or emergency braking can easily lead to tire puncture. Therefore, the tires should be inspected regularly, the tire pressure should be reduced appropriately, or nitrogen gas with more stable physical properties and difficult expansion should be filled into the tires to avoid unnecessary accidents.
4. Wiper
There is a lot of rain in summer, so the use frequency of wipers will be high. Therefore, it is particularly important to check the wiper regularly. Pay attention to the cleanliness of the wiper to prevent the wiper from being affected by impurities or dust, affecting the use effect and adversely affecting the front windshield of the car. Once noise occurs, it should be handled in time. Repair or replace in time when problems are found.
4 car maintenance misunderstanding
First, the oil is not satisfied.
Many car owners know that insufficient oil will damage their cars, but they don't think that too much oil will damage their cars. According to industry insiders, adding too much oil is a mistake that novices are prone to make.
Second, frequent waxing does not stop
Many car owners like to wax their cars often, thinking that they will not be afraid of acid rain and heavy snow, but also make the car paint dazzling, but they don't know that waxing often will bring great harm to the car.
Waxing can be done once a month. When waxing, it is best to choose car wax with moderate decontamination ability and no abrasive components.
Third, the tire pressure ratio is low.
When you go to a 4S shop for maintenance, you usually provide free pumping service. Some car owners like to let the staff inflate the tire pressure a little higher, thinking that it can overload and save fuel.
This is not correct. Excessive tire pressure will reduce the tire contact surface, increase wear and tear, and it is easy to puncture. At the same time, because the tire pressure is too high, it will reduce the adhesion coefficient of the tire, reduce the braking effect when braking, increase the side slip, and cause great harm to driving safety.
Similarly, too low tire pressure is not good, which will cause shoulder wear, tire damage and increased fuel consumption. So the correct way is to inflate according to the standard air pressure marked on the tire, and the inflation amount is generally 5% of the standard air pressure.
Fourth, the tighter the fan belt, the better.
The tighter the fan belt, the better. Some car owners feel worried when they see that the fan belt of their car is loose, and they will take the initiative to tighten it when maintaining it.
