How to Check the Remaining Fuel in the Tank?

Both analog and digital fuel gauges require the vehicle to be started before readings can be taken. The analog fuel gauge is marked with two letters, E and F. E stands for Empty, indicating the tank is empty, while F stands for Full, indicating the tank is full. The closer the needle is to the letter F, the more fuel remains; the closer it is to the letter E, the less fuel remains. When the fuel icon lights up, it indicates that the remaining fuel is low and refueling is needed as soon as possible. Below are some additional details: 1. The fuel gauge only provides a rough estimate of the fuel level and cannot display the exact remaining amount, serving merely as a reference for the driver. For example, a digital fuel gauge might show a remaining range of 300 kilometers, but in reality, due to factors like road conditions and vehicle status, the actual range might only be 150 kilometers. 2. The fuel system mainly consists of four parts: the fuel gauge, sensor circuit, variable resistor, and float. When the tank is full, the resistance value of the variable resistor connected to the float decreases, causing the circuit current to reach its maximum. At this point, the fuel gauge needle is at its highest position. As the fuel level drops, the resistance value of the variable resistor increases, reducing the circuit current and causing the fuel gauge needle to lower accordingly.

What are the reasons for changing a license plate number?

Generally speaking, license plates cannot be changed at will as they serve as proof of personal identity. Unless there is a special need, they cannot be replaced. Additionally, if you want to change your license plate, you can first check if there are any surplus quotas available. For example, if a couple has two quotas under their names, then a change is possible. Relevant information about license plate numbers is as follows: 1. Introduction: A license plate number is an identifier for a vehicle, much like an ID number is to a person. For instance, if a car's license plate is from Guangzhou, Guangdong Province, 'Yue' represents Guangdong Province, and 'A' represents Guangzhou. Thus, 'YueA' is the license plate code for Guangzhou. 2. New energy vehicle license plates: Small new energy vehicles use a gradient green color, while larger new energy vehicles use a yellow-green combination. Both symbolize green, environmental protection, and technology.

How to Open the Hood of BYD Song Pro?

Shift to "P" or "N" gear and pull up the EPB switch. Then pull the front hood release handle located on the lower left side of the dashboard. Insert your fingers under the front edge of the front hood to locate the hood latch. Push the latch upward until it releases the front hood, then lift the front hood. Pull it over about 36 degrees, then release your hand to let the front hood fall naturally. Check if the latch is securely locked.

What Causes Car Vibration When Braking with Air Conditioning On?

Here are the specific reasons for car vibration when braking with air conditioning on: 1. Suspension system failure: The suspension system is mainly responsible for filtering engine vibrations during operation. If there is a problem with the suspension, these vibrations will be directly transmitted to the steering wheel and the cabin, affecting driving. When the engine is idling, turning on the vehicle's electrical system can also easily cause vibrations. The engine increases its load due to the electrical system being turned on, causing the idle speed to drop. To compensate for the vibration caused by the idle speed drop, the engine will automatically increase the speed. When turning on the electrical system, especially the air conditioning, the engine often vibrates. This vibration is likely caused by aging suspension components and requires timely replacement. 2. Unstable oil pressure: If the engine carbon deposits have been cleaned, the throttle body has been cleaned, and the oil pads have been replaced, but the car still vibrates, it is recommended to check the fuel supply pressure and the intake pressure sensor at a repair shop. If the fuel pump supply pressure is abnormal or the intake pressure sensor values are incorrect or malfunctioning, it can cause car vibration. 3. Cold start: The main reason for car vibration during a cold start is insufficient fuel combustion, resulting in insufficient power. The ignition energy is relatively low, and when starting, with lower temperatures of fuel and lubricating oil, more throttle is needed to meet the power demand. Over time, the gap between the spark plug electrodes gradually increases, leading to decreased ignition energy and poor fuel atomization, which causes car vibration. Additionally, aging ignition coils, aging spark plug high-voltage wires, or leakage can also reduce ignition energy.

How to Start a BYD Car When the Key Fob Battery is Dead?

If the car has a keyhole, you can use the mechanical key to start the vehicle. You can press the brake pedal or the "Start/Stop" switch, which will cause the smart start system warning light to illuminate and the vehicle's buzzer to sound once. Within 30 seconds after the buzzer sounds, bring the electronic smart key close to the "Start/Stop" switch, and the buzzer will sound again to indicate that the engine can be started. Within 5 seconds after this buzzer sound, press the "Start/Stop" switch to start the engine.

What Causes Slow and Weak Return of Electric Power Steering Wheel?

Slow and weak return of the electric power steering wheel is caused by changes in the four-wheel alignment parameters and damage to the steering gear. Here is how to deal with an improperly aligned car steering wheel: 1. Wheel Dynamic Balance: A car's wheel is an assembly of the tire and rim. However, due to manufacturing reasons, the mass distribution of this assembly cannot be perfectly uniform. When the wheel rotates at high speed, it creates a dynamic imbalance, causing the wheel to shake and the steering wheel to vibrate while driving. To prevent or eliminate this phenomenon, balance weights are added to correct the balance of the wheel edges. This correction process is commonly known as dynamic balancing. 2. Adding Lead Weights: Many attentive car owners may notice small lead weights of varying sizes attached to the edges of the wheel rims. These weights may seem out of place compared to the sleek rims, but they play a crucial role in ensuring stability at high speeds. 3. Four-Wheel Alignment: The installation of the car's steering wheels, steering knuckles, and front axle has specific relative positions. This installation with fixed relative positions is called steering wheel alignment, also known as front-wheel alignment. Front-wheel alignment includes caster, camber, toe-in, and toe-out for the two front steering wheels. Similarly, the rear wheels have their relative installation positions with the rear axle, known as rear-wheel alignment, which includes camber and toe-in for each rear wheel. Collectively, front-wheel and rear-wheel alignment are referred to as four-wheel alignment.
