What should you pay attention to when driving on the highway for the first time?

Before the car goes on the highway, you need to check the following items:

1. Tires

This is the first part to check. The tires of the car are like If a person's legs are broken, can he still walk?

Check the appearance of each tire carefully to see if there are any scratches. If the rubber is only scratched, it will not affect use, but if the tire lines inside are damaged, new tires must be replaced. If the tires have not been used for more than two years, it is best to replace the two front tires with the rear tires. Carefully check the consistency of the four tires, drive on a flat road without holding the steering wheel, and see if you can run in a straight line. Otherwise, quickly do a four-wheel alignment.

1. Check the tire tread; generally, when the tire tread depth is less than 2mm, it cannot be used for long-distance running.

2. Measure the tire pressure; generally, a car tire pressure of 2.5 is enough, not too high or too low.

3. Check the spare tire; confirm that the spare tire is in good condition and confirm whether the spare tire pressure is up to standard.

2. Engine oil

Put the car on a flat place. After the car is cool, unplug the oil dipstick. Wipe it clean with a rag before inserting it. After inserting it all the way, pull it out and check. , the engine oil level only needs to be within the minimum upper limit/maximum upper limit of the oil dipstick scale, and cannot exceed the scale range.

You need to consider the local climate of your destination. If you go to the Northeast in winter, you must consider the viscosity of the engine oil. You can consult the local maintenance center whether it needs to be replaced.

3. Antifreeze/glass Water

Antifreeze can prevent the coolant from freezing and expanding when the car is parked in cold winter, causing the radiator and engine cylinder to freeze and crack. Antifreeze needs to be used year-round.

Similar to the method of checking engine oil, the scale for antifreeze is usually on the box. Just make sure that the antifreeze level is within the scale.

It is indispensable to drink glass of water when driving at high speeds, especially in rainy and snowy weather, so it is best to fill the glass of water before traveling and have it as a backup.

4. Lighting

Including driving lights, reversing lights, brake lights, turn lights, interior lights, fog lights, etc., especially fog lights. If there is a problem, please Replace immediately. During a journey, the weather you encounter may change. In bad weather, the role of light is particularly important. If a light bulb is damaged during daily use, it is best to replace it and repair it in time.

5. Brakes

Look at the thickness of the brake pads. If they feel too thin (less than 2mm), they need to be replaced.

Drive at normal speed and apply the brakes to see if there is anything unusual. Park the car on a slope and see if the handbrake works.

6. Battery

Many car owners don’t pay much attention to the inspection and maintenance of the battery. In fact, the battery is the heart of the car’s electronic control system.

Battery also has a service life. If the service life is more than 3 years and the climate of the destination is relatively cold, be sure to check it before running a long distance. In addition, it is best to bring two battery cables with you in case of emergency. needs.

Some car batteries have an observation hole. If the battery light is white, it means that it needs to be charged. If the battery light is black, it means that the battery needs to be replaced. If there is no observation hole, just measure the battery voltage in the flameout state. If it is greater than 12V, there will be no problem. If you don’t have a measuring tool, you can judge based on whether the car starts smoothly and whether the headlights are bright enough.

7. The whole vehicle

Check whether there are cracks in the glass, whether the door switch is abnormal, whether the instrument panel is working normally, the air conditioning and heating functions, the position of the reflector, the horn, the navigation, and the steering. , wipers, etc. These are also things that need attention on a daily basis.

8. Tools

Some necessary self-rescue tools in the car: jack, 6mm~19mm wrench/socket, slotted/phillips screwdriver, window breaking tool, traction strap, etc. /p>

Some necessary emergency equipment in the car: warning triangle, fire extinguisher, warning lights, etc.

Necessary documents for driving: driver's license, driving license, insurance policy, etc. Hope this helps you Hope to adopt it. Thank you!
