I just handled the Service B reminder for my Mercedes-Benz C200L, and the method is actually quite simple. First, sit in the car and close all doors, then turn the key to the second position to power on without starting the engine—the dashboard will light up. Next, don’t leave the buttons on the left side of the steering wheel idle; press the return button on the left to access the menu, where you’ll find a maintenance option. Select it and reset the Service B reminder. The system will ask if you’re sure about resetting—just confirm, and it’s done. The whole process takes about a minute, but if the car is parked on a slope, it’s best to engage the handbrake for safety to avoid distractions during the operation. After resetting, I tested starting the car several times, and the reminder didn’t pop up again, confirming the reset was successful.

How to Check if the Throttle Body Needs Cleaning?

Methods to check if the throttle body needs cleaning: The most obvious sign of a dirty throttle body is unstable acceleration, which can usually be felt by the driver. The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. Connected to the air filter at the top and the engine block at the bottom, it is often referred to as the throat of the car engine. The responsiveness of the car's acceleration is closely related to the cleanliness of the throttle body. Cleaning the throttle body can reduce fuel consumption and make the engine more responsive and powerful.

Does the Driver's Field of View Angle Decrease as Vehicle Speed Increases?

As the vehicle's speed increases, the driver's gaze point moves forward, and the range of observation on both sides of the road narrows. Here are the specific details regarding the field of view angle: 1. Field of View Width: At a speed of 64 km/h, the driver's field of view width is 37 degrees, which sharply decreases to 13 degrees at 97 km/h. 2. Driving Conditions: At lower speeds, drivers expand their field of view by moving their eyes or turning their heads. At high speeds, they can only focus intently on the road ahead. The time available for drivers to observe and react to surrounding environmental conditions decreases, leaving insufficient time to detect potential hazards and take timely emergency measures. Additionally, as speed increases, the driver's visual acuity declines, making it easier to focus on the road ahead while neglecting the surroundings. As vehicle speed increases, the driver's gaze point tends to fixate further into the distance, resulting in a narrower field of view angle and blurrier vision. Moreover, prolonged high-speed driving can lead to driver fatigue, increasing the likelihood of operational errors.

Should You Use Internal or External Air Circulation for Car Heating in Winter?

Whether to use internal or external air circulation for car heating in winter depends on the situation. For short trips, internal circulation is suitable; for long-distance driving, it is recommended to use external circulation to replenish fresh air. If driving in heavy traffic, internal circulation is advisable to prevent exhaust fumes from entering the car. During winter, car air conditioning is used almost daily for both heating and cooling. The heating principle of car air conditioning is much simpler than cooling. When heating, the engine's hot coolant flows through the heater core, and the air blown by the blower passes over the heater core, allowing warm air to flow out of the vents.

Where is the motorcycle frame number located?

The stamping location of the frame number varies depending on the brand and model of the motorcycle. For most cross-type motorcycles, the frame number is stamped on the steering head tube at the front of the frame (in front of the fuel tank). Some underbone motorcycles also have it stamped in this location, while others may have it stamped on the frame under the seat or beside the frame. For scooters, the frame number is often stamped on the front underbone near the footrest or on the left/right side of the frame bottom. Some models may have it stamped on the frame under the seat cushion or near the engine. Daily maintenance tips for motorcycles: 1. During the break-in period, keep the idle speed at 100 rpm; 2. Match the gear with the corresponding speed; 3. When braking is needed, release the throttle, press the rear brake with your right foot, and gently apply the front brake with your right hand; 4. Regularly inspect the spark plug; 5. When installing a new spark plug, hand-tighten it until it stops, then use a spark plug wrench to tighten it an additional 1/4 to 1/2 turn; 6. Regularly lubricate the chain.

Will the insurance company repair or compensate for a water-damaged car?

Insurance companies will repair water-damaged cars. Below are the specific details regarding this matter: Introduction: In the event of a vehicle being submerged in water, the auto damage insurance can cover the cost of repairing parts of the vehicle other than the engine. However, damage caused to the engine itself can only be claimed under the additional water damage insurance. Water damage insurance is a specific add-on coverage for the engine and must be purchased separately! Vehicles with water damage insurance can receive compensation for engine damage caused by driving through waterlogged roads or being submerged in water. Relevant information: If a vehicle is submerged in water or engine damage occurs due to driving through water, the auto damage insurance will not provide compensation. If a vehicle is soaked in water but the engine is not affected, and only parts replacement or circuit repairs are needed, this falls under the coverage of auto damage insurance. Even if the entire vehicle is submerged, leading to a total loss, the insurance company can provide full compensation. If water damage insurance is not purchased, the insurance company will only compensate for losses incurred when the vehicle is stationary and submerged, provided no attempt was made to start the engine. However, if the vehicle is driven through water despite foreseeable risks, resulting in damage, the insurance company will not provide compensation.

What does it mean when the car displays 'STOP'?

When a car displays 'STOP', it indicates a mandatory stop alarm. In such cases, the engine operation should be stopped immediately. The main reasons for this alarm light to illuminate include low oil pressure, low brake fluid level, or high coolant temperature. The mandatory stop alarm light is connected to the engine oil pressure, brake fluid level, coolant temperature gauge, and electronic brake force distribution system. It is not an independent warning light. After this warning light comes on, other corresponding components of the car should be checked. It's important to note that this alarm light usually comes in two colors: yellow represents a general fault, while red indicates a serious fault.
