Car owner's car knowledge】Cars are just like people, they have "fever and cold" from time to time, just like in daily life, no one has to go to the hospital for any illness. Many new car drivers also view some minor faults in the car in this way, but many times because they do not understand the car, they often "misdiagnose", and the original minor fault is magnified to replace the entire component, which is undoubtedly a waste of time and money. So let's take a few examples that are often "misdiagnosed" by drivers.

Maintenance

Back door won't open

Maintenance

The passenger in the back seat was about to get out of the car, but found that the door could not be opened at all. As a result, the handle was gently opened from outside the door. A novice might think: Oops, it looks like the door lock is broken. In fact, it's just the child safety lock that comes into play. In order to prevent children from accidentally opening the door from the inside of the car, many vehicles are equipped with child locks. If the device is accidentally activated, the rear door can only be opened from the outside of the car. In this case, just turn off the child lock. Some cars have the child lock position on the door handle of the rear door, and some cars arrange the lock position on the side of the rear door, which can only be adjusted when the door is opened.

Air conditioner not cool enough

Maintenance

Some novices often envy the coolness of the air conditioner in other people's cars, but their own car only feels "not too hot" when the air conditioner is turned on to the maximum, and every time the air conditioner is turned on in the sun, it takes a long time for the car to cool down. . You probably overlooked what the inner and outer loop buttons do. If the vehicle starts the air circulation inside and outside the air conditioner, the cooling effect will be significantly reduced, but the advantage is that the air is relatively fresh. On the contrary, if the internal circulation of the air conditioner is simply used, the cooling capacity will be greatly improved, but the disadvantage is the lack of internal and external air exchange, and the air in the cabin is not fresh enough.

Steering wheel stuck

Maintenance

When you start the car, you are surprised to find that the car key cannot be turned, or the steering wheel is stuck. In this case, don't think that the car is broken, ask someone to repair it, because it is just the steering wheel lock of the car. The steering wheel automatically locks after parking, which is a very common feature on sedans. Although the steering wheel lock is primitive compared to most electronic immobilizers, for thieves, even if the car is successfully started, the steering wheel cannot be turned, so it still has a good anti-theft effect.

Suspension feels too stiff

Maintenance

Obviously, I felt quite comfortable when I bought the car. Why is the suspension so stiff when I drive it now? And I didn't feel such a strong bumpy feeling when I rode in other people's cars of the same style. In this case, it is necessary to pay attention to check whether the tire pressure is too high. Tires are actually very important shock absorption facilities on the car. When the tire pressure is appropriate, the tire can absorb the bumps from the road well, but if the tire pressure is not appropriate, especially if the tire pressure is too high, the tire will lose shock absorption. Ability.

Fuel consumption is too high

Maintenance

There is also a big problem that newbies often have a headache, that is, fuel consumption. Fuel consumption is the most important criterion to distinguish a novice from a veteran. The novice not only does not know enough about the route, but also does not know enough about the temperament of the vehicle. Driving a manual transmission car, often in low gears at high speeds or high gears at low speeds, will have a great impact on the engine and fuel consumption. When driving an automatic car, the novice does not know how to use the depth of the accelerator to control the gear, and it is reasonable for the fuel consumption to remain high.

The above situation may be rare in the driving process of the old driver, because after a long time, you will have a deep understanding of the car, and each button knows what to use. But it is inevitable that some new drivers will be nervous when they encounter this situation, which is due to the lack of understanding of the functions of the car. There are many similar examples, which tells us not to be too nervous when encountering some superficial faults, maybe just a small button makes us have a wrong judgment.
