Car waxing teaching video tutorial

1. The first step: Preparation. First, make sure that the surface of the car you are going to wax is clean and dust-free and can be wiped with water or car cleaner. Then, prepare the necessary tools and materials, including waxing agents, sponges, soft brushes, rags and spray bottles.

2. Wash the car and remove dust. Before waxing, you must rinse your car and keep the car body clean and dry. The dampness of the car body will cause the car wax to be uneven when waxing, and debris or dust on the car body will scratch the paint. Body waxing.

3. After waxing, don't wipe the car body with a towel to deal with the dew or fog every morning, which will make your previous work useless; as long as you wipe the glass, you can drive. After the moisture evaporates, gently brush off the dust with a feather duster or soft cloth depending on the situation.

4. Wipe off the unnecessary car wax after the body is dry with a microfiber cotton towel, and sand and polish until the body shows a beautiful luster. Check whether there is residual car wax in the car body, and properly dispose of the residual car wax of the license plate number, headlights and car doors.

5. Generally, there are garage parking, and most of them are vehicles driving on good roads. The correct way to wax cars is to wax every 3-4 months. For open-parked vehicles, it is best to wax every 2-3 months due to wind and rain.

How to drive an automatic transmission car video tutorial

First, open the car door, sit in the driver's seat, and Good seat belt.Then, insert the key into the ignition switch and turn on the power of the vehicle. Next, put the gear lever of the car on the P gear. This is the parking gear of the automatic transmission car, which means that the vehicle has completely stopped.

P parking gear: The vehicle must stop completely before using the P gear, otherwise the mechanical part of the automatic transmission will be damaged. When parking, you can put the wheel in the P position for mechanical locking to prevent slipping. When the Rover starts, the engine can only start in "P" or "N" gear to avoid the car suddenly jumping forward when starting in other gears.

Step on the brake pedal first, and then start the engine. At this time, don't release the brake pedal. Put down the handbrake and put it in D gear, and then release the brake pedal to move forward. Automatic transmission cars need to step on the brake pedal before starting the engine and placing it in D gear, otherwise the engine cannot be started or put in D gear.

How to run-in automatic transmission cars video teaching

Video Part 1: Smooth acceleration and deceleration During the running-in period, sudden acceleration and sudden braking should be avoided as much as possible. The driver should accelerate and slow down smoothly to avoid too much burden on the vehicle. In the video, we will show you how to accelerate and decelerate smoothly.

The journey of the grinding machine is generally 500 kilometers. The running-in speed is not required to be too fast. Just keep the speed at 60-70 kilometers per hour, and the speed should not exceed 2200. In the middle of the running-in period of 500km/h to 1000km/h, from 60km/h to 70km/h to 90km/h to 100km/h, the speed is still below 2,500rpm.

Check the equipment. The equipment should be checked before each time you go on the road. During the inspection, you can know whether each function can work normally through the display of each instrument. If it can work normally, you can be ready to go on the road. If there is a problem with a display, it should be dealt with as soon as possible. Pay attention to changing the speed of the car.

The running-in of the automatic transmission new car: heat the car first when starting: after starting the vehicle, it takes a certain amount of time for the oil to fully lubricate from the bottom shell to the various parts of the engine. If you drive immediately, it is easy to aggravate the wear of the engine.

When running in the running phase, avoid sudden braking and rapid acceleration. Automatic transmission cars, because manual gear shifting cannot be used to determine the specified gear, can only be achieved through driving speed.
