Checking the safety of vehicles before driving is a good way to ensure driving safety, which can find faults as early as possible and deal with them in time, especially for friends who are not familiar with car conditions such as part-time drivers or borrowing cars.

First, check the cold car 1, and check the tire pressure of the vehicle. Generally, the air pressure has been measured when inflating tires, but after driving or stopping for a period of time, air leakage may occur, resulting in insufficient tire air pressure and affecting driving safety. If there is a measuring instrument, you can measure the air pressure. If not, you can check the tire air pressure by looking, knocking and squeezing. 2. Check the engine oil and brake oil. First, pull out the oil meter to see the oil level and oil quality; The second is to look at the amount of oil in the brake tank; The third is to see if there is oil leakage under the car; 3. Check the cooling water. Mainly depends on whether there is enough water in the water tank.

Second, start the vehicle inspection 1 and check the fuel. First of all, look at the amount of oil displayed by the oil meter; The second is to ask whether the oil meter is accurate and effective. If the fuel meter is broken, it is best to fill it up at the gas station before leaving the car, and at the same time, zero the odometer to judge the fuel consumption by the mileage of the vehicle. 2. Check whether the oil pressure displayed on the oil gauge is normal. 3. Check the braking system. First, try to press the brake pedal to see if it works. If you don't step on your foot to the end and there is no response, then the brakes may be invalid. Vehicles with air brakes should also check whether they are inflated and whether the air pressure can meet the requirements; Second, after releasing all the brakes, see if the brake indicator light on the dashboard is on. If yes, there may be too little brake oil:

The third is to start the vehicle and try whether the brakes are really effective. 4. Check whether the water temperature meter is too high and too fast. 5. Check the lighting system to see if the turn signals, brake lights and far and near lights are effective. 6. Check the direction. Mainly check whether the steering wheel is light and flexible, whether the interval is too large, and whether there is abnormal noise.
