Mercedes-Benz active brake icon reminder may appear due to the following reasons: abnormalities in the brake system, manifested as poor or failed braking, unilateral braking deviation, or braking noise. Below is relevant information about Mercedes-Benz active braking: 1. Solution: If the braking force weakens, stop immediately and wait for assistance. If the brake system warning light is on, first check if the handbrake is fully released. If the light remains on after releasing the handbrake, inspect whether the brake fluid level is normal or if the brake pads are too thin. 2. Activation conditions: The system activates when a collision is imminent or when there is an obstacle ahead and the driver shows no reaction.

When the Mercedes-Benz Active Brake Assist icon lights up, it means I've also encountered this while driving a friend's car. This indicates the vehicle's assistance system has detected a potential collision risk or a malfunction. Common causes include the front radar or camera being covered by mud, false sensor alerts, the system needing recalibration, or unstable battery voltage. While driving, this flashing icon may remind you to maintain a safe distance or manually intervene with braking. Don't ignore it, as Active Brake Assist is a crucial anti-collision feature that can automatically decelerate to prevent accidents. It's recommended to immediately pull over and check the cleanliness of the sensors; if there's dust, try wiping them clean. If the icon remains lit, you should visit an authorized dealership for diagnostics to prevent larger hazards. After all, safety comes first. Mercedes-Benz designs this system intelligently, and regular maintenance can make driving more reassuring.

How many kilometers can a gasoline car drive on a full tank?

A full tank of gas generally allows a car to drive around 600 kilometers, and it will not be less than 500 kilometers. The driving range of a car is directly related to the amount of fuel. The size of the fuel tank measures a car's capacity to hold fuel, and the size of the fuel tank is directly related to the car's fuel consumption. Typically, a full tank can drive more than 500 kilometers. For example, a car that consumes 10 liters per 100 kilometers usually has a fuel tank capacity of around 60 liters. The fuel tank capacity varies for different car models, and even for the same type of car from different brands. Below are some fuel-saving tips for driving: Control RPM: Every car has an optimal RPM range where fuel consumption is relatively low. For most fuel-injected cars, the engine RPM should ideally be between 2200 and 2500. Maintain speed: Controlling speed while driving can be challenging. The most fuel-efficient driving condition is maintaining a steady speed in a straight line. The most fuel-efficient speed for small-displacement cars is between 60-80 km/h, while for mid-displacement cars, it is between 80-100 km/h. Driving at the optimal economical speed ensures the best fuel efficiency.

How to Repair the Steering Lock Malfunction in Volkswagen Touareg?

Volkswagen Touareg steering lock malfunction may result in the steering wheel being locked; it is advisable to seek professional repair services immediately. Methods to address the steering wheel lock malfunction in Volkswagen Touareg: Hold the steering wheel with your left hand and gently shake it while simultaneously turning the key with your right hand to unlock it. For enhanced security, vehicles are equipped with an automatic steering wheel locking feature, which also serves as an anti-theft measure. The principle behind the automatic steering wheel lock is that after parking the car and removing the key, when the steering wheel is no longer under any control, the slightest movement will cause the lock inside the steering wheel to pop out, blocking or engaging the central rotating shaft of the steering wheel. At this point, the steering wheel cannot be moved until it is unlocked. For vehicles with key ignition, if the key position is below the steering wheel, the key controls the steering wheel lock. Insert the key, gently shake the steering wheel, and then turn the key to unlock it. For vehicles with automatic start-stop, start the engine and gently shake the steering wheel to unlock it. Alternatively, when entering the driver's seat with the key, gently shake the steering wheel until the lock loosens to unlock it. Never use excessive force; avoid forcefully pulling or shaking the steering wheel. Instead, gently shake it to create a slight gap between the central shaft of the steering wheel and the lock, allowing the lock to automatically reset. Features of the Volkswagen Touareg: Appearance: The Touareg is a low-key yet luxurious SUV that is highly sought after in the domestic market, often leading to shortages. As a luxury SUV, its selling point must be "luxury." The wide chrome grille and rectangular air intake grille reflect the traditional design of the Volkswagen family. Off-road performance: In terms of the Touareg's functional configuration, it excels not only on asphalt roads but also in off-road capabilities. Another feature that sets the Touareg apart is its understated yet muscular appearance. The proportions of the body are perfectly balanced, whether it's the waistline height, window area, or trunk size, all of which are well-proportioned, giving the vehicle a solid, stable, and trustworthy overall impression.

How Long Does the ETC Device Battery Last?

Generally, an ETC device can last 2-3 months on a single charge. The ETC user manual does not specify the duration of a single charge. For vehicle owners who do not frequently use ETC, it is recommended to charge the ETC device every 3 months. For wired ETC devices that are not used for a long time, it is advisable to charge them once a month to prevent battery lifespan reduction due to self-discharge. ETC devices are divided into solar panel charging and wired charging. ETC devices with solar panels do not require manual charging, while wired ETC devices need to be charged using a charger. ETC stands for Electronic Toll Collection, which is an electronic toll payment system. To apply for ETC, the following documents are required: the vehicle owner's valid ID card and vehicle registration certificate (original and copies), and if the application is handled by a proxy, the proxy's valid ID card is also needed. The copy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is required. Applicants must be between 18 and 60 years old and own the vehicle in their name. For the current year's vehicle insurance policy, corporate applications require the handler's ID (or driver's license), the company's organization code certificate (or business license), and the company seal. How ETC works: The onboard electronic tag installed on the vehicle's windshield communicates with the microwave antenna in the ETC lane at toll stations. Backend computer networking technology is used to settle payments with the bank, allowing vehicles to pass through highway or bridge toll stations without stopping to pay fees. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass through toll stations without stopping; Cost-saving: Reduces vehicle wear and fuel consumption by minimizing start-stop cycles, and users can enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment systems, ETC technology is more mature and advantageous.

How often should Evans Waterless Coolant be replaced?

To determine when to replace the coolant, the first method is to refer to the coolant's instruction manual, which will provide details about the product. Generally, coolant is added to the radiator and has a service life of less than 2 years. The second method involves a DIY approach: open the radiator and inspect the turbidity of the liquid inside. If it appears very cloudy and contains floating particles that may corrode the metal parts of the radiator, replacement is recommended. Below are relevant details: Precautions: After filling the vehicle with coolant and normal driving begins, regularly check the coolant level (especially during the first few days or within 3,000 kilometers). If the level drops, promptly investigate the cause and replenish as needed to prevent reduced effectiveness due to evaporation of residual water in the cooling system or the expulsion of trapped air. Also, be vigilant for leaks. If coolant leakage occurs, promptly drain and collect it for sedimentation. After repairs, it can be reused. Increased vibration and noise: Localized overheating inside the engine can increase pre-ignition and knocking tendencies, leading to heightened vibration and noise, significantly reducing engine performance and efficiency, and resulting in waterless fuel consumption.

What is the fuel tank capacity of the BYD S7 in liters?

The fuel tank capacity of the BYD S7 is 72 liters, as officially announced. Owners who have purchased the BYD S7 can also check this information on the vehicle's configuration sheet. The BYD S7 requires 92-octane fuel, with a fuel consumption of 7.5 to 8.8L per 100 kilometers. A full tank can cover a distance of approximately 818 to 960 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel added may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to a safe fill level, leaving some space between the safe fill level and the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.
