Stand by and pull over and wait for the mechanic to talk about it.

Many new and old drivers like to inspect their cars themselves, and even some car owners like to do simple maintenance work for their cars themselves without professional training. But it should be noted that if it is not handled properly, it will cause danger.

What must be paid attention to when the vehicle has problems and needs to be repaired by itself?

Avoid: don't put warning signs when repairing cars on the roadside.

Master Tip: Repairing cars on the roadside is a very risky thing, and the traffic will be dangerous to you at any time.

What to do: When repairing a car on the side of the road or waiting for rescuers on the road, be sure to set up a warning sign about 50 meters behind the car. If there is no warning sign on the car, you can find some branches or obstacles around to mark it, so as to achieve the effect of warning the vehicles behind you and avoid traffic hazards.

Avoid: running the engine for a long time in an unventilated garage.

Expert tip: Many car owners start their cars in a closed space, ignoring the influence of exhaust gas from the engine. Automobile exhaust is actually very dangerous, containing carbon monoxide, which is an invisible, odorless and toxic gas that can easily enter the passenger compartment. If the owner inhales low-concentration carbon monoxide gas in a closed or poorly ventilated space for a long time, it will cause symptoms such as headache, shortness of breath, nausea and vomiting, dizziness and even brain damage.

What to do: Never run the engine in a closed space. 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. Even if you are outdoors, don't stay near the exhaust pipe of the working engine for a long time.

Avoid: the tubing is blocked and sucked by mouth.

Expert tip: 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 concentrations of sulfide, and hydrogen sulfide is also toxic. If the oil pipe is blocked, the owner will suck it with his mouth in order to get through the pipe, and it is easy to suck gasoline into his stomach, causing nausea, abdominal pain and even poisoning or death.

What to do: If the vehicle is driving on the road and the oil pipe is blocked, remember not to suck the oil pipe with your mouth, especially leaded gasoline. In case of inhalation, you should go to the hospital in time after forcing yourself to vomit. If the oil pipe is blocked, you'd better call a professional rescuer for help.

Avoid: Open the hood when the car is boiling.

Master tip: use a car in summer, and it is easy to boil when it is hot. When the car is boiling, the driver should not check it himself, because if the hood is opened in the boiling situation, the steam temperature of the water tank is too high, which may easily lead to burns on the face or other parts of the body.

What to do: If the engine boils, stop the car at the side of the road, put out the fire, pull out the key, hang up the hood, let it naturally ventilate and dissipate heat in the shade, and then call professional rescuers.

Avoid: park the broken car on the half slope for maintenance.

Expert tip: Like the situation at the beginning of the article, some car owners will park their broken cars directly on the half slope for maintenance, and forget to pull the hand brake, which will eventually cause serious accidents.

What to do: When parking, the car should mainly pay attention to whether the parking place is a slope, and it is best to find a flat place without a slope. Check whether the car is still in gear and pull the handbrake. If there is a slope, it is best to put obstacles under the wheels to prevent the vehicle from sliding suddenly.
