How to Adjust Rearview Mirrors for a New Car?

Here are the steps to adjust the rearview mirrors for a new car: 1. Sit in the driver's seat and adjust your body posture to find the most comfortable and relaxed driving position. This seating position must allow your feet to easily reach the accelerator and brake pedals. 2. First, adjust the left rearview mirror. The vertical position should be adjusted so that the sky and ground each occupy half of the mirror, and the horizontal position should be adjusted so that the car body occupies about one-quarter of the left rearview mirror. 3. For the right rearview mirror, the horizontal position should also have the car body occupying one-quarter, but the difference is that the ground should occupy two-thirds of the right rearview mirror, with the sky occupying only one-third. 4. Because the driver's position is generally on the left side of the car, there is some visual deviation. Only by adjusting the mirrors to this state can you clearly see the cars on the right side.

What is the difference between ABS tire pressure monitoring and ordinary tire pressure monitoring?

The differences between ABS tire pressure monitoring and ordinary tire pressure monitoring are: 1. Difference one: The ABS tire pressure monitoring system uses the wheel speed sensors of the car's ABS system to compare the rotational speed differences between tires to achieve tire pressure monitoring, while ordinary tire pressure monitoring systems use tire pressure sensors to detect the rotational speed of the car tires to reflect the tire pressure. 2. Difference two: The car's ABS braking system can perform braking operations based on the distance the car travels and the speed at which it is moving. This function is generally automatically activated at speeds above 30 kilometers per hour. On the other hand, ordinary tire pressure monitoring systems work by installing four tire pressure monitoring sensors inside the tires. These sensors automatically monitor the tire pressure and temperature in real-time, whether the car is stationary or moving, and provide timely alerts for high pressure, low pressure, or high temperature in the tires to prevent traffic accidents caused by tire failures, ensuring driving safety.

What Causes a Clicking Noise When Braking in Reverse?

Here are the reasons for a clicking noise when braking: 1. When braking produces a sharp screeching sound, apart from new pad break-in, the first thing to check is whether the brake pads are worn out or if there are foreign objects. If the brake pads are worn out, they should be replaced immediately. If foreign objects are present, the brake pads should be removed to extract the objects before reinstalling. 2. When braking produces a dull thudding sound, inspect the brake caliper for worn sliding pins or detached spring plates. If found, replace them promptly. 3. When braking produces a hissing sound, it's recommended to first check whether there are issues with friction between the caliper, brake disc, and brake pads. 4. When braking produces a rattling noise, inspect whether the attachments on the brake pads have loosened. The best solution is to either reinforce them or replace the brake pads entirely.

What Are the Causes of Car Idle Vibration?

Car idle vibration can be caused by spark plug failure, excessive carbon buildup, or fuel supply system issues. Spark Plug Failure: Spark plugs are wear-and-tear parts. They need to be replaced when excessive carbon buildup or excessive ignition gap is detected. Excessive Carbon Buildup: Idle vibration during car operation is often caused by carbon deposits. During engine operation, carbon deposits can form on the throttle body and fuel injectors. Excessive carbon buildup can lead to inconsistent air-fuel mixture concentration in the cylinders, which is most noticeable during cold starts. It is recommended that drivers ensure the cleanliness of the throttle body during daily driving. Fuel Supply System Issues: Malfunctions in the car's fuel supply system can cause unstable air-fuel mixture concentration, resulting in vibration during idle. It is necessary to promptly inspect the car's fuel filter.

What does the Mercedes-Benz fault code P012800 mean?

Mercedes-Benz fault code P012800 indicates that the Engine Coolant Temperature (ECT) is below the thermostat regulating temperature. Possible causes of this fault: The vehicle's thermostat is equipped with a ball valve to control the volumetric flow rate of the coolant. Fault code P012800 may be caused by a stuck ball valve. Solution: Replace the thermostat: The thermostat is mostly located on the right side of the engine, connected to the radiator lower hose; removing the air filter box allows clear visibility of the thermostat assembly. Before removing the thermostat, first detach the hose clamp and pull out the hose; remove the thermostat core, clean the interface thoroughly, and install a new thermostat core. If the thermostat aluminum housing gasket is aged, it must also be replaced.

What are the pros and cons of large car wheels?

Large wheels have the advantage of improved safety performance; the disadvantage is reduced comfort and shock absorption. Major advantages: The biggest benefit of large wheels is improved safety performance, because large wheels have smaller tire aspect ratios, lower heating rates at high speeds, and smaller pressure changes. Therefore, cars with large wheels, wide tires, and low aspect ratios will have improved safety performance. Additionally, large wheels help enhance off-road capability. Disadvantages of large wheels: Due to the thin sidewalls, tires on large wheels often have weaker resistance to external impacts. They are prone to bulging when driving on rough roads, and sharp objects may even cause blowouts directly. Moreover, almost all large wheels are heavier than small wheels, and thin tires cannot balance this weight, leading to increased unsprung mass, which negatively affects fuel consumption, handling, and comfort. In other words, large wheels significantly reduce the car's shock absorption and comfort.
