What does used car preparation mean?

Used car preparation refers to the process of conducting a comprehensive inspection of the vehicle's documentation and overall condition. Below are the relevant details about used car preparation: 1. Re-establishing the used car records: Creating an information file for the used car. Some used cars entering the market may already be in a state where the insurance has expired or there is no insurance at all, a condition commonly referred to as "uninsured." Some may also lack complete maintenance records. 2. The significance of used car preparation for both buyers and sellers: From the perspective of the original owner, preparation might simply involve washing the car and organizing the vehicle's documents, which could be considered as completing the task. However, for the next owner, this approach may seem somewhat irresponsible. 3. The content of used car preparation by dealers: Reputable used car dealers will immediately start creating a new maintenance record for the vehicle after acquisition. The main tasks include checking whether the vehicle has been involved in any accidents, assessing the extent of damage caused by any accidents, conducting a thorough inspection and maintenance of the vehicle, and replacing or repairing any necessary parts. Finally, the vehicle undergoes a detailed cleaning.

What are the tips for the automatic transmission Subject 2 driving test?

Subject 2 operation tips: 1. Note: Use D gear and idle speed throughout the test, do not step on the accelerator to speed up, drive steadily and slowly. 2. Parallel parking: If you can't see the rear wheels in the side mirrors when parallel parking, you can stick your head out or tilt your head to look at the mirrors. 3. Hill start: Pay attention to the hill stop if you're not confident. When starting on a slope, shift to D gear, release the handbrake, and control the accelerator to avoid stalling or rolling back. 4. Right-angle turn: Before entering a right-angle turn, you can slow down or stop to straighten the wheels or align the car body, staying as close to the right side line as possible. 5. Curve driving: Don't turn the steering wheel too sharply when driving through curves; try to take a wider path after entering the curve. 6. Reverse parking: Maintain idle speed throughout the reverse parking process, accurately judge your position, control key points and timing, and know how to make minor adjustments when deviations are noticed through the mirrors.

How to Control Speed While Driving?

Driving speed is controlled by depressing the clutch and applying the foot brake. Here are detailed instructions on speed control: 1. Technique: Speed control can be practiced by driving in a straight line while continuously operating the clutch and foot brake. The clutch should be depressed quickly and released slowly, with minimal pedal movement at all times. For parallel parking and curve driving, lightly tapping the foot brake can effectively reduce speed. 2. Precautions: Always pay close attention to traffic signs along the route and strictly adhere to their regulations. Adjust speed flexibly according to road and driving conditions.

What Causes the Rattling Noise in Hill Descent Control Braking?

The causes of abnormal brake noises in cars are as follows: 1. Use of low-quality or overly hard brake pads: If low-quality or overly hard brake pads are used, they will produce a squeaking noise when they rub against the brake disc during braking. Therefore, it is essential to use high-quality brake pads when replacing them. 2. Presence of sand or foreign objects between the brake pad and brake disc: While driving, it is inevitable to encounter complex road conditions. Due to the unique design of disc brakes, some sand or foreign objects may get between the brake pad and brake disc, causing abnormal noises during braking. 3. Severe wear of the brake disc: For new cars, a slight squeaking noise during braking is normal and will diminish with more driving. For older cars, the brake disc and brake pads may have rusted. In this case, removing them and sanding off the rust layer can help. Alternatively, if the brake pads are severely worn, they should be replaced. 4. Brake pad warning: There is no strict rule on how many kilometers brake pads should be replaced; they should be replaced when they become thin. Some brake pads have electronic warnings, while some lower-end cars use warning tabs. If the wear reaches the warning line, a squeaking alarm sound will be emitted, indicating the need for immediate replacement. 5. Incorrect installation of brake pads: If the brake pads are installed incorrectly or the model does not match, abnormal noises will occur. The brake pads should be reinstalled properly. Car owners should have brake pads installed at professional auto repair shops, especially those who have had them replaced at roadside stalls, as extra caution is needed.

Why does the steering wheel shake when braking at around 60 km/h?

Here are the reasons why the steering wheel shakes when braking at around 60 km/h: 1. Tire deformation: Lift the front axle and rotate the wheels to check the static balance of the wheels and whether the tire or wheel hub is excessively deformed. If deformed, they should be replaced. 2. Tire dynamic imbalance: The car may experience steering wheel shaking within a certain speed range, requiring wheel dynamic balance to be redone. 3. Vehicle drivetrain malfunction: It is necessary to check whether the alignment angles of the front wheels meet the requirements, and adjustments should be made if they are off. 4. Part detachment: The ball joint of the half-shaft tie rod is worn and loose, or the rubber sleeve at the joint has fallen off, requiring replacement of the damaged parts.
