These four things must be checked before self-driving during the Spring Festival

The New Year is approaching, and many people choose to travel by car during the Chinese New Year. There are thousands of roads, and safety is the first priority. The two most important things for self-driving travel are safe arrival and smooth arrival. In addition to maintaining a high degree of vigilance and concentration while driving, , the most important thing is to ensure that the transportation is in good condition, and since most repair shops will be closed during the Spring Festival, it will be much more difficult to solve problems than usual. This requires inspection and preparation in advance, which will be listed below There are several items that must be checked before long-distance self-driving.

Must check

Coolant

Coolant is one of the most important aspects of engine operation. It is mainly responsible for controlling the engine operating temperature. Coolant shortage and leakage are one of the faults that will occur with a high probability no matter what type of vehicle, so you must pay special attention to it. Check the status and level of the coolant. If it is found to be lacking, add it in time. If it is lacking again, check whether the pipeline is aged or cracked.

The lack of coolant will lead to high engine temperature, thereby causing irreversible losses. If you find that the vehicle alarms due to excessive temperature, you must pull over immediately to avoid irreversible consequences.

engine oil

The habit of checking the engine oil before a long trip is not necessarily exclusive to vehicle owners with excessive oil loss, because there may be unexpected and uncontrollable factors. For example, in the editor's own situation, after maintenance at the 4S store, due to The repairman failed to tighten the screws, resulting in oil leakage. Considering the age and engine characteristics of this car, there is almost no possibility of burning oil, so the oil level has never been checked. Fortunately, someone traveling with me reminded me that there was a pool of oil under the car. Check in time that no irreversible losses have been caused after replenishing the oil.

For car owners with fixed oil consumption, the editor’s reminder may be insignificant, but I still have to remind you that the Spring Festival is a special period. In order to avoid finding a merchant to buy it when needed, don’t forget to prepare enough oil. loss in order to ensure the smoothness of the entire journey.

Check brake fluid

The most important thing about safety is whether it can brake. Brake oil is the most critical part. It is necessary to ensure that the water content and other hard indicators of the brake oil do not exceed the standard at all times. Remember! It must be ensured that it is within the normal working range! Safety is no small matter.

Know the condition of your tires

As the only part of the vehicle that is in contact with the ground, tires are also the part directly linked to safety. Safety cannot be ignored, and tires cannot be ignored. The following points are required for tire inspection.

1. The most important thing is to check whether the sidewall is damaged. As the most fragile part of the tire, the sidewall is the part that we must take strict care of, because damage to the sidewall will directly lead to a puncture.

2. Whether the tires are eccentrically worn. If the tires are eccentrically worn when driving at high speed, it will easily lead to a tire blowout. Some vehicles will have serious wear on one side of the tire, such as the BMW 5 Series GT with chassis code F07. The eccentric wear of the inner tire is difficult to detect on the outer side, so special attention is required to check.

3. Check whether there are nails in the tires. Be sure to carefully check the integrity of the tire tread. In this case, there is a risk of tire blowout.

4. Check the tire pressure. The tire pressure needs to be kept within the value recommended by the manufacturer. The value is marked below the B-pillar of the main driver or passenger driver on some models.

5. Check the tire wear marks. Each tire has a limit wear mark. When the tread is parallel to the wear mark, it means the tire needs to be replaced.

6. If possible, you can do a dynamic balance. If you don’t drive at a high speed and at a constant speed, it will be difficult to detect the jitter caused by the dynamic balance. This jitter can range from discomfort to the steering wheel to jitter to the entire vehicle, which has a greater impact on the long-distance driving experience. Seriously, or if you have the conditions, find a high-speed test to see if there is jitter.

Try to check

Check spare tire and vehicle tools

The spare tire is also one of the inspection items that is often ignored. Checking the tire pressure of the spare tire and whether it can be used normally can greatly reduce the extra energy expenditure caused by tire emergencies. If the vehicle does not have a spare tire, you need to check whether the current tires are run-flat tires. If they are ordinary tires, it is best to purchase a set of emergency tire repair equipment to support it to the repair shop in case of emergency.

light inspection

Since the exterior lights are in a position where it is difficult for the driver to notice whether they are working properly, it is necessary to check the exterior lights of the entire vehicle regularly, especially before traveling long distances. It is not uncommon for car lights to fail, especially vehicles that use tungsten filament bulbs and have no warnings in the car, so they should be inspected carefully.

Especially for the rear profile lights, there will be safety hazards if the single-side profile light fails, and there will be major safety hazards if the double-side lights fail. In a dark environment, the lookout of the vehicle behind is not timely or has a certain speed. Poor, it is very easy to cause a collision accident.

Battery check

This inspection is very necessary for car owners traveling north, because the battery is the most necessary factor for successfully starting the vehicle and will cause performance degradation as the temperature decreases. If you don't notice that the battery has reached the end of its service life, leaving it in a lower temperature environment overnight can easily cause the vehicle to fail to start.

Wiper and glass water inspection

During the Spring Festival, there is no lack of heavy rainfall and snow. In this kind of weather, the existing road conditions cannot be selected. Good visibility is our best effort. The aging of the wipers, insufficient pressure and other conditions will affect the weather in the strong snow. Especially obvious below.

Glass water is one of the most ignored consumables, but glass water is directly linked to safety in certain circumstances. For example, after the rain and snow stop, the car in front throws a lot of mud and water. It is unimaginable that when the front windshield is covered with small mud spots, How to drive safely. Especially at high speeds, it is impossible to stop the car and there is no chance to manually pour water, which greatly affects the safety of the vehicle. It is recommended to prepare sufficient replenishing glass of water.

Summarize

Safety is no small matter. The only important thing on the road is to arrive at the destination safely. When preparing for my trip, the editor has always been prepared for all foreseeable emergencies. When it comes to safety, no matter how big or small it is, I hope that everything will be safe. The driver friends set off safely and arrived safely.

Hayne's Law points out: Behind every serious accident, there must be 29 minor accidents, 300 near misses, and 1,000 accident hazards. It is also the responsibility of every driver to eliminate all hidden dangers. Drivers are also reminded to keep a reasonable distance between vehicles during travel, and do not drive fatigued. I wish you all safety.
