Should You Press the Clutch When Braking in a Manual Car?

When braking in a manual transmission car, you must press the clutch. 1. The correct method is to first press the brake and then press the clutch to shift gears. The specific operation method depends on how much speed you need to reduce. 2. If you only need to slightly reduce speed, for example, from 70 km/h to 65 km/h, you can directly press the brake without pressing the clutch. However, if you need to significantly reduce speed but not stop, 3. For instance, if you are in 5th gear at 70 km/h and need to reduce the speed to 10 km/h, failing to press the clutch and applying heavy braking will cause the car to start shaking when the speed drops to a certain point, such as below 30 km/h. If the speed drops further or the car stops, it may stall. In such cases, you should first press the clutch and then apply the brakes.

Is the Annual Inspection Label Replaced Every Year?

Annual inspection labels are not replaced every year. New vehicles are exempt from annual inspections for the first six years, but it is required to collect and replace the annual inspection and environmental protection labels on the vehicle every two years. The validity period of the motor vehicle inspection can be checked on the vehicle license or the compliance label. The process for vehicle annual inspection is as follows: 1. Fill out two forms: the Motor Vehicle License Application Form and the Motor Vehicle Inspection Record Form; 2. Go to the annual inspection registration window to review and input the materials; 3. Visit the violation inquiry window to pay any outstanding fines if there are violations; 4. Have the vehicle undergo an external inspection by an inspector, who will check the vehicle identification number (VIN) under the hood and provide a signed inspection approval page, then proceed to the inspection payment window to receive the invoice; 5. Submit all materials at the inspection registration window; 6. Wait in line for the inspection, and receive an inspection report upon completion; 7. Submit the annual inspection materials to the staff; 8. Once the inspection is passed, the annual inspection label will be issued.

How to Use a Tire Pressure Gauge?

When using a tire pressure gauge, press the air nozzle connector firmly onto the tire valve stem to depress the valve core. The value displayed on the gauge is the tire pressure. During measurement, ensure the pressure gauge is properly aligned with the valve stem to prevent air leakage, as this can lead to inaccurate readings. Standard tire pressure values: According to the international GBT2978-2008 standard, the recommended tire pressure for standard tires is 2.4-2.5 bar. When to adjust tire pressure: Generally, it is recommended to check tire pressure at least once a month and adjust it seasonally. The ideal times for adjustment are November and May. In November, as winter approaches, tire pressure typically decreases and may require slight adjustment. In May, as temperatures rise, check if the pressure is normal. Notably, if the tire pressure is within the standard range, do not intentionally reduce it. If the tires are not underinflated, monthly adjustments are unnecessary.

Can Car Wheel Hubs Be Repainted?

Car wheel hubs can be repainted. According to relevant traffic management regulations, there are no explicit rules regarding the color of wheel hubs, and the color of wheel hubs is not included in the 30% color change limit for the entire vehicle. Changing the color of wheel hubs will not affect road legality or annual inspections. The wheel hub is the rotating part of the tire's inner rim connected to the wheel center via spokes, and it is the metal component mounted on the axle that supports the tire. Methods for maintaining wheel hubs include: 1. If the vehicle is located in a humid area, the wheel hubs should be cleaned frequently to prevent salt corrosion on the aluminum surface; 2. When necessary, after thorough cleaning, wax can be applied to the wheel hubs to maintain their shine; 3. When the wheel hubs are at a high temperature, they should be allowed to cool naturally before cleaning. Using cold water for cleaning can damage the aluminum wheel hubs, cause brake disc deformation, and affect braking performance. Using cleaning agents on wheel hubs can trigger chemical reactions on the surface, leading to loss of shine.

What Causes Car Shaking and Engine Light Illumination?

Car shaking and engine light illumination can be caused by: 1. Engine carbon buildup: When carbon accumulates excessively in the engine, its operational state becomes abnormal, leading to intensified engine shaking; 2. Poor fuel quality: Low-quality fuel may not burn completely in the engine, producing impurities that can clog internal engine passages, triggering the engine warning light; 3. Overheating inside the engine can cause knocking. When the ECU detects engine knocking, it attempts to mitigate it by delaying ignition. If the knocking exceeds the ECU's adjustment capacity, the engine warning light will illuminate along with persistent knocking.

What are the 1.8t cars?

1.8t cars include Citroen C5, Changan CS75, Geely Boyue, imported Audi A6, etc. Here, 't' stands for Turbo, which refers to an engine equipped with an intake turbocharging device. 1.8t means a 1.8-liter displacement engine with an added intake turbocharging device. A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. The new Dongfeng Citroen C5 features a simple overall interior design, with the steering wheel changed from the original four-spoke to a three-spoke design. The new Changan CS75 adopts a large-sized front grille design with five chrome strips for decoration, integrated with the headlights, which also feature a new design. The Boyue retains the family-style front face, with three pentagon-shaped chrome strips embedded in the front grille and connected to the headlight clusters on both sides, complemented by a large trapezoidal air intake below and new-style fog lights on either side. The Audi A6 features a multi-horizontal-slat front grille, and the rear exhaust layout adopts a dual-exit design.
