The hazards of refueling without turning off the engine: 1. When opening the fuel tank cap, fuel may spray out, creating a safety hazard; 2. The engine continues to run with current flowing, which can lead to short circuits or leakage, posing a significant fire risk; 3. The surrounding area of the car generates considerable heat. During refueling, the concentration of fuel vapor mixed with air around the tank increases. If a spark occurs while the vehicle is running, the gasoline molecules in the air can easily ignite, leading to danger. Precautions for refueling: 1. Do not use mobile phones; 2. No smoking; 3. Turn off the engine and power supply before refueling.

Why can't the Buick GL8 shift gears?

Introduction to the reasons why the Buick GL8 cannot shift gears: Cold weather: Difficulty in shifting gears due to cold weather is a normal phenomenon. After starting the car and driving for a while, the transmission temperature rises, making shifting easier. Gear damage: The positioning parts of the gear lever's positioning ball head lose function, allowing the gear lever to rotate freely around its own axis, making it impossible to control the gears accurately. Spherical surface wear: Wear on the spherical working surface at the lower end of the gear lever prevents it from controlling the fork or the groove of the shift head, making both shifting and disengaging gears impossible. Transmission failure: Damage to the transmission computer can cause the car to have issues with shifting but not moving. Solutions: Warm up the car for a while before driving. Take the car to a repair shop to inspect the gear components and replace any worn parts promptly. Reset the transmission computer using a diagnostic tool. If the manual does not mention how to reset it, seek assistance from an after-sales service for resetting.

How to Use Turn Signals for Pulling Over in Subject 3 Driving Test?

In the Subject 3 driving test, the correct way to use turn signals when pulling over is to activate the right turn signal immediately after the voice announcement, and turn it off when the vehicle comes to a complete stop. Below are relevant details about pulling over in Subject 3: 1. Pulling over technique: Approach the curb at a 30-40 degree angle. When the right front corner of the vehicle reaches the sideline, turn the steering wheel left to straighten the vehicle. There's no need to precisely measure the distance between the vehicle and the sideline - just get as close as possible. 2. Precautions: The timing for activating the turn signal is crucial - neither too early nor too late. Generally, you should activate the turn signal right after hearing the "pull over" voice announcement.

Can touch-up paint be leveled by polishing?

Touch-up paint cannot be polished because the applied paint lacks hardness and will come off if polished. Below is a detailed explanation about it: 1. Introduction 1: For minor scratches, prevention is key. Protect the paint surface when it is still new by applying a layer of mirror glaze. Mirror glaze mainly consists of high-molecular polymers and is applied directly to the paint surface. After cleaning the car body, use a polishing machine or manual operation to vibrate and press the mirror glaze into the paint, forming a protective mesh-like film that significantly enhances the paint's hardness. 2. Introduction 2: If the scratches on the car body have exposed the primer, localized touch-up painting is required.

How to Prevent Paint from Peeling on Electroplated Surfaces?

To prevent paint from peeling on electroplated surfaces, follow these methods: 1. Method One: Ensure the car surface is clean before painting, free from rust, acids, alkalis, and dust or dirt. 2. Method Two: Use appropriate techniques and a controlled spraying environment, maintaining proper temperature and humidity, and apply a thicker coating. 3. Method Three: If using baked paint, the baking process is crucial; factors like temperature and duration significantly affect adhesion. Apply an adhesion promoter between the substrate and the paint layer to enhance interlayer adhesion and resolve peeling issues.
