What are the common issues causing uneven wear on rear tires?

Uneven wear on rear tires is generally caused by abnormal tire pressure, tire dynamic imbalance issues, wheel alignment problems, or suspension issues. Abnormal tire pressure: Either there's excessive difference in pressure among the four tires. Overinflation causes severe wear on the central part of the tire, while underinflation leads to severe wear on both sides. Solution: Adjust all four tires to the appropriate pressure. Tire dynamic imbalance issues: If there's a problem with tire dynamic balance, the tire may show patchy wear patterns. Solution: Rebalance the tires. Wheel alignment problems: If there are wheel alignment issues, one side of the tire may wear more significantly. Excessive camber causes severe outer edge wear, while insufficient camber leads to severe inner edge wear. Solution: Perform wheel alignment again. Suspension issues: Such as loose ball joints or misaligned front suspension systems. In fact, inaccurate wheel alignment also falls under suspension problems. Suspension issues may cause sawtooth wear patterns on the tire tread or excessive wear on individual tires. Solution: First inspect the condition of independent suspension springs and shock absorbers to identify the specific problem.

Why does the car shake violently after replacing the fuel injectors?

After replacing the fuel injectors, the car shakes violently because the throttle body is too dirty. Dirty throttle body and excessive carbon buildup in fuel injectors: When a car has been driven for a certain mileage, a dirty throttle body can cause the throttle valve to not close properly or the idle stepper motor to get stuck, both of which can lead to excessively high engine idle speed. Additionally, carbon deposits generated during engine operation can also cause vehicle shaking, especially when starting the car. The engine may shake more violently than usual, and in some cases, it might not start on the first attempt. Therefore, when the vehicle experiences shaking, the throttle body and fuel injectors should be checked first. If the throttle body is found to be too dirty or the fuel injectors have excessive carbon buildup, they should be cleaned promptly. Steps for cleaning the throttle body: If there is a plastic heat shield cover on the engine, remove it. Disconnect the air ducts around the throttle body and note their positions. The side of the throttle body near the combustion chamber is usually dirty, with black carbon deposits, which is the main area to be cleaned. Cleaning the throttle body primarily involves removing carbon deposits, using specialized cleaning solutions or carburetor cleaners. These cleaning agents can be harmful to humans, so gloves and a mask should be worn during cleaning.

Where is the Focus rearview mirror heating switch located?

The Focus rearview mirror heating switch is located on the rearview mirror adjustment position. Simply press the heating symbol, and when the rear window heating function is activated, the exterior rearview mirror heating function will automatically turn on. The rearview mirror heating feature is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rainwater or fog, eliminating the need for frequent manual wiping by the driver and thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is required, as there is an adjustment button on the driver's side. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within minutes, typically between 35-60 degrees Celsius. The heat will dissipate from the left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface will shrink, and fog will gradually disappear, thereby heating the mirror and removing frost. If the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves adding electric heating wires to the mirror. These wires consume a significant amount of power. When using the rearview mirror heating function, ensure the car is in an active state. Avoid activating the heating function while the car is stationary to prevent draining the battery and leaving insufficient power to start the vehicle. Other methods for defogging rearview mirrors include: Opening windows for airflow: Crack open the side windows slightly to create air circulation between the inside and outside of the car. As the temperature difference decreases, the fog will gradually disappear. Adjusting the car's air conditioning to the appropriate setting can also use warm air from the AC to defog the mirrors.

What does it mean when the preventive safety system stops working?

Preventive safety system stop working means that the vehicle's airbags, active head restraints and pre-tensioned seat belts will all stop functioning. Below is relevant information about the preventive safety system: 1. Function: During emergency braking, the enhanced brake assist system quickly calculates the required braking force for the current situation. During emergency avoidance maneuvers, the electronic stability program rapidly stabilizes the vehicle to reduce the risk of skidding. 2. Definition: When encountering dangerous situations such as severe oversteer, understeer, sudden steering movements, panic braking or emergency braking, this system can take preemptive measures including automatically closing the sunroof and side windows, tightening seat belts and adjusting power seats to a more appropriate position.
