4matic temporarily unavailable means there is a malfunction in the all-wheel drive system, causing this function to be disabled. How 4matic works: The core technology of Mercedes-Benz 4MATIC four-wheel drive is the 4ETS differential limiting technology. 4ETS utilizes the automatic braking force distribution function of ABS to achieve differential limiting. When a wheel of this all-wheel-drive vehicle slips, the onboard computer applies braking force to the slipping wheel via ABS to limit its spinning. This allows the differential to transfer the power intended for the slipping wheel to other non-slipping wheels. Advantages and disadvantages of 4matic: Advantages: The 4MATIC all-wheel-drive system is compact, lightweight, and offers optimized friction performance. Compared to other all-wheel-drive systems, its advantages are quite significant. Disadvantages: 4MATIC is mostly suitable for urban roads and has very limited off-road capabilities. Reasons for 4matic being unavailable: Malfunction in the related system control program; failure in power distribution; data transmission failure: this requires specific checks on the wiring and connectors between various systems and components.

Is the New Battery Fully Charged?

New batteries are not fully charged. Precautions for the first charge: Regarding the charging time for the first charge, since the battery is unused when it leaves the factory and has not undergone charging and discharging, it is necessary to ensure the battery's normal operation. Generally, the charging time should be controlled at about 5-6 hours to fully charge the battery. Subsequent charging durations can follow the instructions on the battery manual, typically 8-10 hours. During the first charge, the battery should be fully charged, but fully charged does not mean overcharging. Charging during the day makes it easier to control the charging time, preventing overcharging and discharging during the first use, which helps ensure the initial chemical reactions inside the battery proceed normally. Battery maintenance: Charge promptly. If the battery is frequently "depleted," the battery plates can be easily damaged, so timely full charging is crucial. Before starting, ride the electric vehicle like a bicycle for a while before turning on the power. This can reduce the damage caused by high current to the battery plates. Deep discharge: After a period of use, the active material in the battery may settle. If not activated in time, it can affect the battery's capacity. Charger: Do not purchase fast chargers, as they can damage the battery plates. Use a battery protector, which can eliminate battery sulfation and keep the plates "clean," thereby extending the battery's lifespan. Batteries are sensitive to high temperatures, so avoid exposing them to direct sunlight.

What does 'new car with flatbed truck' mean?

The meaning of 'new car with flatbed truck' refers to the logistics vehicle dispatch center matching the corresponding flatbed truck for transporting the vehicles to be shipped. Vehicle flatbed matching process: According to the order, wait until a full truckload is assembled in one area, then the logistics transportation department begins loading and shipping to various destinations. Vehicle flatbed arrival time: Generally speaking, for destinations in provincial capitals: within 1000 km takes 2-3 days, 1000-2000 km takes 3-5 days, and 2000-3000 km takes about a week. The vehicle shipping time depends on whether you choose single-vehicle small flatbed truck or 6-8 car large transport truck for consignment.

What is the Function of a Motorcycle Carbon Canister Check Valve?

Motorcycle carbon canister check valve is a device used to reduce air pollution caused by fuel evaporation emissions and simultaneously increase fuel efficiency. Working principle of the motorcycle carbon canister check valve: Due to the airtightness of the fuel tank, fuel consumption creates negative pressure inside the tank. Under this negative pressure, gasoline vaporizes more easily than under normal pressure. When the engine is turned off, the carbon canister stores the mixture of fuel vapor and air emitted from the fuel tank in the micropores of the activated carbon inside the canister, preventing the fuel vapor from escaping into the atmosphere. When the engine starts, the solenoid valve installed between the activated carbon canister and the intake manifold opens, delivering the fuel vapor stored in the carbon canister to the engine for combustion, thereby reducing emissions and fuel consumption. Carbon canister check valve: When the vehicle starts, the solenoid valve opens, releasing the adsorbed fuel vapor into the intake manifold to be burned in the engine. The carbon canister is the most critical component in this system, responsible for collecting and storing gasoline vapor. The carbon canister installed in the vehicle is actually an assembly. Its shell is usually made of plastic, filled internally with activated carbon particles that can adsorb vapor. The top is equipped with a purge control valve to regulate the amount of gasoline vapor and air entering the intake manifold, as well as a filter screen to purify the gasoline vapor, among other components.

Is It Allowed to Drive with the Trunk Open?

No, it is not allowed to drive with the trunk open, as doing so constitutes a traffic violation. Prohibited behaviors while driving a motor vehicle include: Driving when the doors or compartments are not properly closed; hanging or placing items within the front or rear window range of the driver's compartment that obstruct the driver's view; making or receiving handheld phone calls, watching TV, or engaging in other activities that interfere with safe driving; stalling or coasting in neutral gear on steep slopes; throwing items onto the road; driving a motorcycle with hands off the handlebars or hanging items on the handlebars; driving continuously for more than 4 hours without stopping to rest or resting for less than 20 minutes; honking the horn in areas or sections where it is prohibited. Penalties for driving with the trunk open: Driving with the trunk open is a violation, but electronic police cameras will not capture it. Such violations are managed by traffic police. Once discovered and the vehicle is stopped by traffic police, a ticket will be issued, which may result in a warning or a fine as per regulations.

Is it necessary to change summer tires in winter?

Summer tires can be used in winter, but their performance is not as good as winter tires. Types of tires available domestically: Currently, there are three types of tires available domestically: summer tires, winter tires, and all-season tires. All-season tires have broader applicability and offer moderate performance. Functions of tires in different seasons: Winter tires have softer tread rubber, making them highly suitable for winter use, especially on snow-covered roads. Compared to summer tires, winter tires significantly improve traction on icy and snowy surfaces, ensuring better grip performance and shorter braking distances. Differences between summer and winter tires: Tread design varies; summer tires are primarily designed for normal temperatures and dry road conditions, while winter tires are designed for low temperatures and snowy/icy surfaces. To prevent slipping caused by icy or snowy roads and loss of grip due to hardened rubber in cold temperatures, winter tires are made from special materials that are softer than summer tires. Additionally, their tread patterns and grooves are deeper and wider to ensure better traction and grip during winter driving.

What brand is the helmet with three vertical bars?

The helmet with three vertical bars is the Hyundai Veloster. The protective function of helmets: The function of a helmet is to protect the head. It is mostly semicircular in shape and mainly consists of three parts: the shell, the lining, and the suspension system. The shell is made of materials such as special steel, fiberglass, reinforced plastic, leather, and nylon to resist damage from bullets, shrapnel, and other impacts to the head. Choosing a helmet: In the field of helmets, there are currently only national standards for motorcycle helmets and sports helmets. Therefore, the quality of electric bicycle helmets varies significantly. Experts suggest that in the absence of national standards, consumers can opt for sports helmets as their safety performance can basically meet the requirements. When purchasing, the quality of the helmet can be judged by smelling it. If the foam inside the helmet has an odor, it may be made from recycled materials, and its impact resistance will be poor. Squeeze it with your hand to see if it deforms. If it deforms under pressure and does not rebound, the helmet is of poor quality. If the foam inside cracks after squeezing, the quality is even worse.
