Solutions for all dashboard warning lights being on in a Mercedes: 1. Charging System Indicator Light: When the ignition switch is turned on but the engine is not running, this light remains on, or if it lights up while driving, it indicates a possible fault in the charging system; 2. Malfunction Indicator Light: When the ignition switch is turned on, the malfunction indicator light turns on, indicating it is working. If the light stays on while the engine is running, it indicates an abnormality in the emission control system; 3. Anti-lock Braking System (ABS) Warning Light: When the engine starts, the light turns on, indicating it is working, and it automatically turns off after a few seconds. If the ABS warning light remains on or lights up while driving, the vehicle needs to be serviced; 4. Brake System Warning Light: If this light turns on, it indicates a fault in the brake system, and the brake system should be checked immediately. Taking the Mercedes C-Class as an example, its body dimensions are 4581mm in length, 1810mm in width, 1448mm in height, with a wheelbase of 2760mm.

What does BSI mean in Peugeot cars?

Dongfeng Peugeot BSI refers to a fault in the interior body control unit, which can be checked with a computer diagnostic tool. Generally, the reset of Peugeot BSI is also known as initialization. If you need to perform this operation, you will need Peugeot's dedicated diagnostic tool. The specific steps are as follows: Select the vehicle model and enter vehicle identification; input the DAM number (taking the Peugeot 307 as an example, the DAM number is located on the inner side of the right front fender), test by control unit; select the central switch unit BSI, connect the OBD diagnostic head, turn on the ignition switch, and choose initialization settings. Resetting the Peugeot BSI requires connecting to a fault diagnostic tool. If your Peugeot BSI needs resetting, it is recommended to take the car to a 4S shop for professional handling rather than attempting to do it yourself.

What Causes the Lack of Power and Jerking During Startup in the Cruze?

Here are the specific reasons for the lack of power and jerking during startup in the Cruze: 1. Clogged engine oil passages: The combustion of fuel, which is the power source of the engine, is determined by the ignition, air intake, and fuel injectors. If the air intake decreases, the ignition weakens, or the fuel injection reduces, the power output will be insufficient, leading to a jerking sensation. 2. Dirty transmission fluid: This can cause damage to the solenoid valves. If sludge accumulates in the transmission fluid and circulates within the transmission, blocking the oil passages in the valve body, jerking issues may arise. Over time, this can lead to a series of transmission problems such as overheating, harsh shifting, and slipping. 3. Break-in period: Mild jerking during driving is normal during the break-in period because the vehicle's power output and component engagement are not at their optimal levels. Additionally, the transmission control module has a self-learning mechanism that continuously adjusts oil pressure for smoother gear shifts.

What does the TC light with a slash mean in the Envision?

The yellow TC light with a slash in the Envision is the Traction Control System indicator. Press the button below the gear shift mechanism, then turn off the ignition and restart to reset the system, and the yellow TC light with a slash will turn off. If the warning light remains on or lights up again while driving, repairs are needed. Possible causes for the TC light to illuminate include: solenoid valve failure; dirty oil clogging the solenoid valve filter; wear on the actuator gear and impeller, leading to oil pressure leakage and triggering the alarm; dirty throttle with an opening reaching 20%; or the engine computer misjudging a TC fault. The working principle of the Traction Control System involves replacing the mechanical connection between the accelerator pedal and the throttle with an electronic throttle device. Sensors transmit the accelerator pedal's information to the ECU, which then generates a control voltage signal based on this information. The motor adjusts the throttle according to the signal, thereby reducing the throttle opening and controlling wheel slip. For drivers operating vehicles in rainy or snowy conditions, this can help reduce occurrences of wheel slip or loss of control.

What are the basic maintenance items for a car?

Basic car maintenance items include oil and oil filter replacement, air filter replacement, fuel filter replacement, and spark plug maintenance. Below are the details of basic maintenance items: 1. Oil and oil filter: Primarily for the maintenance of the lubrication system. The main function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's role is to remove various impurities from the oil, ensuring the normal operation of the lubrication system. The oil filter should be replaced along with the oil during an oil change. Under normal circumstances, the car should be serviced every 5,000 km. 2. Air filter: The air filter's function is to filter the air before it enters the cylinder, removing impurities, dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The fuel filter is generally replaced after driving 20,000-25,000 km. 3. Spark plugs: Spark plugs are consumable parts and should be replaced every 20,000 km. In addition, components such as brake fluid, transmission oil, battery, throttle, fuel injector, and brake pads are all inspection items during routine maintenance, and their maintenance depends on usage conditions.
