When the plastic bumper of a car is scratched, if it's a minor scratch, apply toothpaste to the scratched area and rub it counterclockwise with a soft cotton cloth. Repeat this process a few times to repair the scratch. For scratches that have removed the base coat, use a touch-up paint pen for repair. Shake the paint inside the touch-up pen well, then carefully spray it along the direction of the scratch. After it dries, apply fine wax. More information about car bumpers is as follows: 1. Bumpers are installed at the front and rear ends of a car. They serve functions such as safety protection, vehicle decoration, and improving the vehicle's aerodynamic characteristics. 2. From a safety perspective, bumpers can act as a buffer during low-speed collision accidents, protecting the front and rear body of the car. In the event of a collision with a pedestrian, they can provide some protection to the pedestrian.

Last time my car's bumper got a shallow scratch, I fixed it myself - pretty straightforward. First wash thoroughly with water and neutral detergent to remove grease/dirt. For light scratches, buy a scratch repair compound from auto parts store, apply like toothpaste on cloth and polish in circular motions for few minutes until scratch fades gradually. Deep scratches exposing plastic? Then get putty filler to level, sand smooth after drying, spray color-matched paint in thin multiple coats (no rush), finish with protective wax against oxidation. DIY saves money but time-consuming; must avoid over-sanding damaging paint. Key is learning steps from tutorial videos, preparing gloves/masks/tools - minor issues easily solved, saving hundreds at repair shops. Remember bumpers fear heat/sunlight, park under shade post-repair to prolong lifespan.

What are the reasons for increased fuel consumption?

The following factors affect car fuel consumption: 1. Displacement: The engine displacement has a certain impact on car fuel consumption, but this impact is a fixed value. 2. Tire pressure: Car fuel consumption is also directly related to tire pressure. When the tire pressure is too high or too low, the car's fuel consumption will increase. 3. Road conditions: The road conditions on which the car is driven will also affect fuel consumption. 4. Combined fuel consumption: This is calculated by dividing the total emissions of urban and suburban driving cycles by the total mileage completed in these two cycles, and then using the emissions to calculate the corresponding fuel consumption value.

Why is the Auto Start-Stop Function Not Working?

Reasons why the auto start-stop function is not working: 1. Accidentally pressing the auto start-stop button on the car, causing the system to shut down; 2. The engine has not reached the normal operating temperature, the automatic air conditioning has not reached the preset temperature, the battery storage is insufficient, the steering wheel is turned after parking, the vehicle is in emergency braking, or reversing—these situations will not activate the auto start-stop function; 3. The auto start-stop system is malfunctioning, possibly due to wiring issues or other reasons causing the system to fail. The engine auto start-stop function automatically shuts off the engine when the vehicle comes to a temporary stop during driving; when it's time to move forward again, the system automatically restarts the engine.

Does Turning the Steering Wheel to the Full Lock Position Damage the Car?

Turning the steering wheel to the full lock position does not damage the car. Modern steering systems commonly include hydraulic power steering and electric power steering. In hydraulic power steering systems, a safety valve is installed to prevent excessive pressure and protect the oil pump from damage when turning the steering wheel, so even at full lock, the steering system remains unharmed. Electric power steering systems typically consist of a steering sensor, speed sensor, steering assist motor, and electronic control unit. If the steering wheel is held at full lock for an extended period, the electric power steering system will activate a protective mechanism to prevent overheating of the steering motor by stopping its operation, so there is no need to worry about damaging the car.
