1, intelligent key has no power.
When the vehicle intelligent key has no power, the transmission power of the key is very low, which makes it difficult for the sensors in the vehicle to sense it. At this time, it is impossible to complete the ignition with one button. Generally, intelligent key will be equipped with a mechanical key, which can be directly inserted into the keyhole to start.
2. The gear is not engaged in the P gear.
For automatic transmission (AT, CVT, AMT), the manufacturer will inform in the manual that the ignition must be in P gear.
The steering wheel is locked.
Locking the steering wheel is a simple anti-theft function. When the car is turned off, the steering wheel will lock with a click when it rotates from the return state to a certain angle. When the steering wheel is locked, the one-button start function will not work. Turn the steering wheel left and right, and press the one-button start button of the engine at the same time to release the tension and unlock the steering wheel.
4. The battery voltage is insufficient, dead or damaged.
When driving, people are often waiting for someone. When waiting for someone, they are bored. Some drivers turn on the radio and listen to radio music to kill time. After a long time, the battery may be dead, resulting in abnormal parking.
If the battery is dead, you have to borrow another battery to start it or find some people to start it with the universal cart start method. The failure to catch fire may be due to power failure or battery life expiration caused by long-term headlight failure. In general, the battery should be replaced in time according to the maintenance manual.
In addition, install xenon headlights, high-power audio, DVD, etc. It is also the cause of vehicle circuit failure. It's easy to check whether the car is dead. Just honk the horn. The battery voltage is insufficient, so the starter can't be driven. In this case, you can borrow other batteries and start with connecting wires.
5. The car ran out of gas.
If the fuel gauge shows below the red line, it will naturally fail to catch fire. At the same time, pay attention to the quality of oil. The owner must go to the regular gas station to refuel. When he goes out, he can take a gauze bag at the muzzle to filter out impurities.
6, without antifreeze
Some car owners add water or inferior antifreeze to the car, which causes the whole waterway to freeze. When it is particularly cold in winter, the engine freezes and cracks, resulting in the failure of the car water pump, which can't catch fire and hurt other parts of the engine.
7. Improper operation
This situation often happens in one-button start and automatic transmission vehicles. Make sure that the gear has been reset before starting the car with one button, and then press the start button with your foot on the clutch.
There are also some manual gears that are not started with one button. You won't catch fire if you don't step on the clutch. Therefore, as long as the vehicle has a clutch, it is best to step on the clutch when starting. On the one hand, it can prevent the vehicle from being unable to start, and on the other hand, it can prevent the sudden impact caused by the gear position not being reset.
Common sense of using cars in winter:
1, wiper
If you go out in the morning and find that the wiper is stuck to the windshield by snow water, don't wash it directly with hot water, which will easily cause the window to burst and the wiper to deform due to temperature changes. The correct way should be to turn on the air conditioner with hot air, and the blowing mode is the front windshield until the wiper is turned on naturally.
2. Cooling system
In winter, it is necessary to regularly check whether the water tank, water pump, belt, water pipe, water supply tank and other parts are working normally. If there is any damage or failure, it is best to repair or replace it in time. In particular, some cars have high water temperature in summer, so the repair union will remove the thermostat. Although the problem can be solved in summer, it will be reversed in winter.
3. Warm air
Warm air that has been left for a summer often fails. It is best to try whether there is hot air, whether the fan is running abnormally and whether the air duct is unobstructed. Sometimes the problem is that the antifreeze in the warm air pipe does not flow for a long time, and the condensation blocks the circulation pipe. Although it does not affect driving, it is very troublesome to maintain.
4, antifreeze
Check whether the liquid is in short supply or deteriorated, and replenish or replace it in time if necessary. Antifreeze seems trivial, but it has a great influence on the car, from blocking the pipeline to corroding the cylinder block. Therefore, choose antifreeze carefully. First, don't mix. Second, don't use fake and shoddy products. In addition, generally speaking, antifreeze should be changed once every two years, and it is best to wash the cooling system with clear water before replacement.
5. Machine lubricating oil
Check the label for low temperature, missing or deterioration. In winter, the oil of cold car is too thick, which will affect the start-up and increase the wear of parts. At the same time, too thin oil will reduce lubrication and sealing performance. Choose high-quality compound oil suitable for winter. If it is at or near the specified oil change time, it is best to change it before the weather gets cold.
6. windshield
Keeping the windshield clean is the basic condition for safe driving. In winter, the wiper should be scrubbed regularly to ensure that the windshield can be scraped clean in snowy days. If possible, you can replace the antifreeze windshield to avoid freezing in winter. In addition, some windshield deicer can be added to the glass water. When the windshield freezes, spray glass water on it, and the ice will melt, unlike the usual glass water when it freezes.
7. body
Before winter, it is best to add a protective film to your car. The paint coating or mirror glaze containing PTFE polymer can resist the corrosion of acid rain, snow and salt water. After the snow, the road surface is sprinkled with salt water, and the salt water splashed on the car body is very harmful to the car paint. Take precautions in advance, and you won't be afraid of damaging the car paint when you travel in snowy days.
8. Chassis
In winter, the automobile chassis always deals directly with rain and snow, and it is easy to rust. Flying tires will throw high-salt snow water on the chassis of the car. After the snow was cleared, the car chassis began to rust. Therefore, you'd better take some time to do an anti-rust care for the chassis before winter.
9. Battery
The battery is most afraid of low temperature, and the capacity of the battery under low temperature environment is much lower than that under normal temperature. Therefore, before the arrival of the cold season, the electrolyte of the battery should be replenished and the specific gravity of the electrolyte should be adjusted.
At the same time, clean the terminals of the battery and apply special grease protection to ensure reliable starting and prolong the battery life. If the vehicle is parked in the open air or cold storage for several weeks, the battery should be taken out and stored in a warmer room to prevent the battery from freezing and damaging.
10, tire
Tire rubber will become hard and brittle in winter, and the friction coefficient will decrease, so the tire pressure should not be too high, but it should not be too low. When the outside temperature is low and the tire pressure is too low, the soft tire will accelerate the aging.
In winter, it is necessary to clean up the inclusions in the tire tread frequently, try to avoid using tires that have been mended more than once, and replace tires with larger wear and different brands and patterns. There is a great difference between the internal and external wear of tires. In order to ensure safety and reduce wear and tear, tires should be replaced regularly.
