The battery is covered under the three-guarantee policy. The warranty period for a car battery starts from the date of invoice. During the warranty period, if any issues arise under normal usage conditions, the manufacturer will provide free repair or replacement services for the corresponding parts. However, it's important to note certain details during usage—if improper use is detected, the manufacturer may refuse warranty service. Warranty Period: The warranty period is calculated from the date of vehicle purchase. The battery is classified as a wear-and-tear component, and such components have their own separate warranty periods. There are a total of sixteen parts categorized as wear-and-tear components, each with different warranty durations. The warranty period for the battery is one year, meaning if any issues arise within this period, the battery can be replaced free of charge. Battery Lifespan: Most modern cars use sealed, maintenance-free batteries, which generally do not allow for replenishment or inspection of the electrolyte or electrode plates. You can check the color of the observation window on the battery—normally, it should appear green. The lifespan of the battery depends on the vehicle's configuration and electrical equipment. For example, vehicles equipped with navigation systems, multi-screen displays, remote anti-theft systems, etc., continue to consume power even when the engine is off, leading to prolonged battery discharge. This accelerates the depletion of the electrode plates and electrolyte, making the battery less durable compared to those in manual transmission vehicles. Typically, such batteries last only 2-3 years, while some vehicles may see battery lifespans of 4-5 years.

What is the difference between CarPlay and Bluetooth?

The difference between CarPlay and Bluetooth lies in their usage methods. Below are the distinctions and usage instructions: The differences between CarPlay and Bluetooth include: CarPlay can project the phone screen onto the car's central display, while Bluetooth cannot. CarPlay can be used simultaneously with the radio without audio interference, whereas Bluetooth cannot be used with the radio as the audio channels conflict. Bluetooth is a wireless communication method and is prone to interference, while CarPlay uses wired communication and is less susceptible to interference. The CarPlay system runs on Apple's iOS and is a built-in feature of the iPhone. Usage Instructions: First, enable the "Hey Siri" setting on the iPhone. Then, use Siri to perform tasks such as voice navigation, making calls, sending messages, and playing music. Open the iPhone's Settings, go to General, and select CarPlay. Launch the CarPlay application on the car's display, and connect the iPhone via a USB cable or Bluetooth. Once connected, the car's display will mirror the iPhone's content.

What is the actual fuel consumption of the BJ40?

2.0t models have an average fuel consumption of 12 liters per 100 kilometers, manual transmission 2.3t models average 13 liters per 100 kilometers, and automatic transmission 2.3t models average 14.3 liters per 100 kilometers. Here are some related details: 1. About the BJ40: The BJ40 is a compact SUV that has gained popularity among consumers due to its rugged appearance. It features a body-on-frame design, giving it certain off-road capabilities. The vehicle also has a diesel version, equipped with a 2.0-liter turbocharged diesel engine, though the specific fuel consumption for this model is unclear, and fewer consumers opt for the diesel version. 2. Engine: The BJ40 uses two gasoline engines—a 2.0-liter turbocharged engine and a 2.3-liter turbocharged engine. Neither of these gasoline engines is particularly fuel-efficient, which is expected given that this is an off-road vehicle rather than a sedan.

What does the car button A mean?

Car button A is the automatic parking function switch. The automatic parking function refers to a function that allows the driver to avoid unnecessary vehicle sliding without the need for prolonged braking or activating the electronic parking brake. Introduction to the automatic parking function: The automatic parking function is an extension of the ESP function and is controlled by ESP components. The automatic parking function provides precise parking force through a slope sensor controlled by the controller. When starting the car, the parking control unit calculates information provided by sensors such as the clutch distance sensor, clutch engagement speed sensor, and throttle pedal sensor. When the driving force exceeds the running resistance, the parking brake is automatically released, allowing the car to start smoothly. This significantly reduces the time wasted on judgment based on experience. Automatic parking function: In situations requiring short stops, such as at traffic lights, the system automatically brakes the wheels after the vehicle comes to a complete stop to prevent rolling. During uphill starts, the system automatically brakes to prevent backward sliding. After starting, the system releases the wheels automatically for forward movement. When parking and locking the car, there is no need to pull the handbrake. The system automatically brakes the wheels, but this feature is only available in certain models.

Will stopping to drop off passengers at a traffic light intersection result in penalty points?

Stopping to drop off passengers at a traffic light intersection will result in penalty points, as it is a traffic violation. According to relevant traffic regulations, vehicles are prohibited from stopping at intersections, railway crossings, sharp curves, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, or within 50 meters of these locations. Regulations for temporary parking of motor vehicles on roads: Parking is prohibited in sections with no-parking signs or markings, in road sections with separation facilities between motor vehicle lanes and non-motor vehicle lanes or sidewalks, as well as at crosswalks and construction zones. Parking is prohibited at intersections, railway crossings, sharp curves, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, or within 50 meters of these locations. Parking is prohibited in front of bus stops, emergency stations, gas stations, fire hydrants, or fire stations (including within 30 meters of these locations), except when using these facilities. Doors should not be opened or passengers allowed to board or alight before the vehicle comes to a complete stop, and opening doors should not obstruct the passage of other vehicles or pedestrians. City buses are not allowed to stop to pick up or drop off passengers outside designated bus stops.
