What are the precautions for driving in hot weather?

With the arrival of the hot season and the rising temperature, driving and outdoor parking have become a headache for many car owners. Do you know how to pay attention in such hot weather? The following are the precautions for driving in high temperature compiled by Xiaoshi Bian Xiao, hoping to help you.

Precautions for driving in high temperature 1, to prevent the engine from overheating.

In summer, when the ambient temperature is high, the engine tends to overheat. Therefore, it is necessary to strengthen the inspection and maintenance of the engine cooling system in summer, pay attention to the change of engine water temperature, replenish cooling water in time, and remove the scale in the water tank and water jacket, as well as the sundries embedded between radiator fins. Then, when the engine cooling water temperature is too high to replenish water, be sure not to burn yourself.

When a car is driving for a long time in hot season, it is not easy to drive at a low speed for too long and accelerate too fast. It is not suitable for the engine to work under heavy load for a long time. In order to prevent the water tank from boiling, use antifreeze as much as possible. As we all know, antifreeze has the functions of preventing freezing in winter and boiling in summer, and its boiling point is above 100℃, which can effectively prevent the water tank from boiling in summer. At the same time, always check the tightness of the fan belt, and be careful not to get oil on the belt to prevent the belt from slipping.

2, to prevent gas resistance

As we all know, the higher the temperature, the faster the fuel evaporates, and the easier it is to form gas resistance in the oil circuit. Due to the high temperature in summer, if the vehicle speed is slow and the engine speed is high, it is easy to produce air resistance when it is difficult to dissipate heat, and sometimes it is difficult to start the engine when it is on fire, which will interrupt the fuel supply. Therefore. In summer, the fuel filter should be cleaned in time to ensure smooth oil flow. Once there is air resistance in the fuel system, stop cooling immediately, and move the manual oil pump to the exhaust position to make the pipeline full of fuel. In addition, it should be noted that the braking system of the automobile runs at high temperature and high speed, and the brake fluid will also have air resistance, which will suddenly make the braking fail, so the driver should pay special attention.

3. Prevent the battery from losing water

The high temperature in summer accelerates the evaporation rate of water in the battery electrolyte, which leads to the rapid drop of liquid level, and sometimes the electrode plate will be exposed under the liquid level, resulting in the early damage of the battery due to lack of water. Therefore, the liquid level in the battery should be checked regularly in summer, and distilled water should be added in time to ensure smooth ventilation holes and eliminate oxides in the battery stack. Pay attention to the battery must be installed firmly, and the battery bracket should have enough strength. If the corrosion is serious after long-term use, it should be replaced in time. It is necessary to ensure that the battery does not move or shift when driving under various harsh working conditions to ensure the safety of the battery.

4, to prevent brake failure

In hot summer, brake fluid is easy to evaporate and vaporize in high temperature environment, and it is easy to form air resistance in brake pipeline, and brake shoes are also easy to be ablated, resulting in brake failure. Therefore, the brake system should be checked and adjusted in summer, brake fluid should be added or replaced in time, and the air and impurities in the hydraulic system should be completely drained to ensure that the brake cup, brake hose, brake shoe shaft and brake shoe are in good condition.

5. Prevent the tire from bursting

In summer, the air pressure in vehicle tires will increase with the increase of temperature, which is easy to cause tire puncture accidents. If the tire temperature is too high while driving, stop the car in the shade to cool down, and don't use cold water to cool down. In case the vehicle has a flat tire during driving, if the front wheel has a flat tire, immediately control the steering wheel with both hands and release the accelerator pedal, so that the vehicle can continue to drive in the original direction for a certain distance and then use the road resistance to force the vehicle to stop by itself; If the rear wheel has a flat tire, the car body will generally not have a large inclination angle, and the steering wheel will not rotate except jumping up and down. Don't brake suddenly at this time, so as not to aggravate the danger. Just press the automatic pedal gently and the vehicle will stop slowly.

6, to prevent poor lubrication

When the temperature is high, the viscosity of engine oil decreases, the oxidation resistance becomes worse, and it is easy to cause poor lubrication. Therefore, the quantity and quality of engine lubricating oil should be checked frequently in summer, and engine oil should be added or replaced in time according to the lubricating state of the engine, and the pressure and quantity of engine lubricating oil should be kept within the specified numerical range.

7. Prevent high fever and heatstroke

In summer, the sunshine is strong, the temperature is high, drivers sweat more, consume more energy, and are prone to heatstroke. In order to prevent heatstroke, drivers should avoid eating spicy and greasy food, eat more fresh vegetables, drink more cool drinks, and pay attention to supplementing salt before and during driving.

8. Prevent abnormal combustion of the engine

Abnormal combustion of the engine due to overheating will lead to deflagration, rough operation, power reduction, increased fuel consumption and so on. Abnormal combustion of the engine will cause the temperature of lubricating oil to rise, and the lubrication of moving parts will become worse, which will aggravate the wear of the upper part of the engine cylinder, which is 3-5 times of normal wear, resulting in early engine damage. Therefore, it is necessary to control the engine water temperature in summer to keep the water temperature within the specified range.

Precautions for driving 1. Don't stick to the car in front, keep your distance.

Keep a certain distance from the car in front, no matter in the busy road or the road with few cars, and don't rush with pedestrians and non-motor vehicles. One more thing, pay attention to taxis, buses, trucks and other vehicles.

Second,? Four-word rule? Smooth lane change

Open? Turn on the turn signal; ? Do you see it? Look in the rearview mirror; ? Fight? , hit the steering wheel; ? Close? When you enter the driveway, turn off the turn signal.

Third, drive calmly.

Novice? Driving is generally slow, and it is easy to be tortured by old drivers? Road rage? The dissatisfaction caused? Honk the horn to hurry it up. At this time, as long as it is safe and civilized driving, we must keep calm, remember to be anxious, and even risk speeding up.

4. Don't park illegally or turn around after going the wrong way.

Once you find yourself driving the wrong way or missing the intersection, don't stop or turn around illegally, or make a sudden sharp turn to correct it. Anyway, if you are wrong, you are wrong, and then you will find another opportunity to turn around at the next intersection. Especially when driving in expressway or at night, the above-mentioned error correction behavior is extremely dangerous.

Fifth, try to drive to the middle.

Get into the habit of driving in the middle road outside the city (when there are three lanes on one side). 1, in the absence of isolation belt, taking the middle road can avoid the time to deal with the accident of the opposite car, thus avoiding collision (this is very strict! ), 2, when there is a barrier, I am afraid that someone or a car will suddenly rush out of the barrier. Once it happens, I have time to deal with it. And walking in the middle of the road at night will not be shot by the headlights on the opposite side, and people and cars in the middle of the road will not be seen at all.

Sixth, slow down when turning.

Get into the habit of slowing down and then slowing down when driving around a corner (when crossing with non-motor vehicle lanes and sidewalks)! The habit of observing non-motor vehicle lanes and sidewalks is to pass slowly. This is suitable for avoiding battery cars and pedestrians on non-motor vehicle lanes inside and outside the city. When you turn right in the city, you should politely let pedestrians and battery cars on the crosswalk pass, and ensure that you will not pass slowly after an accident.

Seven, if you can't see clearly, whistle and slow down.

When driving on a mountain road, if you encounter sharp bends or poor eyesight, you should get into the habit of honking your horn early and going slowly, because there are so many motorcycles in the mountain village now, and all the motorcyclists are desperate Saburo without safety awareness. Once an accident happens, you will really be in trouble.

Eight, slow down when crossing the intersection.

When crossing the intersection, whether there are traffic lights or not, whether your driveway is green or not, you should get into the habit of looking left and right (and slow down at the same time), observe the situation of vehicles on the crosswalk, and make sure that there are no cars crossing the intersection before accelerating (and pay attention to the battery car, because the target is small and easy to be ignored).

Nine, look at the rearview mirror before braking.

When you meet a red light at an intersection, you should get into the habit of observing the traffic behind you from the rearview mirror, especially outside the city! Because there are always some drivers (especially truck drivers) who are tired of talking on the phone and can't see the red light, they should habitually look up at the rearview mirror when slowing down to see if there is a car behind them, try not to be in the same lane as the truck behind them, and try to be in the lane without a car in front (if there is a car behind them, you can escape without slowing down). I have been in such a car accident myself. Fortunately, the car behind me was not fast and didn't hurt anyone, but if it was a van, the lesson would be over. Remember!

10. Avoid driving at night.

It is very important to get into the habit of avoiding driving at night when driving outside. There are many outings now, so don't wait until dark. You should set off before dark in a planned way, just in time to get into town. Don't play all day. Don't go on the road until you have finished eating and drinking at night. There are people sleeping beside you. This is a no-no, that's how tragedy happens.
