The BYD F3 equipped with a one-button start function does not have a keyhole inside the car, so you cannot insert a key. When you need to start the car, simply press the one-button start while holding the brake pedal to start the engine, which is very convenient. Just ensure you have the key fob with you. Here are some important points to note about the one-button start: 1. When using the one-button start to ignite the car, you must press the brake pedal and ensure the gear is in neutral or P (park) position. 2. Never press the one-button start while the vehicle is in motion to avoid potential safety hazards. 3. Some cars' one-button start buttons can be removed, revealing a mechanical keyhole underneath. If the one-button start malfunctions, you can use the mechanical key to start the car. However, some models have fixed one-button start buttons without a mechanical keyhole. In such cases, if the one-button start fails, the car must be towed to a repair shop or 4S store for servicing.

Should I Signal When Overtaking in the Far Left Lane?

In the far left lane, overtaking is not allowed. Therefore, there is no need to use the turn signal. Prohibited overtaking situations: According to Article 43 of the "Road Traffic Safety Law": When motor vehicles are driving in the same lane, the following vehicle should maintain a safe distance from the vehicle in front to allow for emergency braking measures. Overtaking is prohibited under any of the following circumstances: the vehicle in front is making a left turn, U-turn, or overtaking; there is a possibility of meeting an oncoming vehicle; the vehicle in front is a police car, fire truck, ambulance, or engineering rescue vehicle performing emergency duties; passing through railway crossings, intersections, narrow bridges, curves, steep slopes, tunnels, pedestrian crossings, or urban areas with heavy traffic where overtaking conditions are not met. Relevant regulations: Motor vehicles passing through intersections should proceed according to traffic signals, signs, markings, or the direction of traffic police; when passing through intersections without traffic signals, signs, markings, or traffic police direction, they should slow down and yield to pedestrians and vehicles with the right of way.

What Causes the Oil Can Light to Illuminate in a Car?

Car fault light illumination reasons are as follows: Cooling and temperature reduction: Engine oil can bring heat back to the oil tank and then dissipate it into the air, helping the radiator cool the engine. Cleaning and purification: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine components back to the oil tank through circulation. The flow of the lubricating oil washes away dirt generated on the working surfaces of the components. Sealing and leakage prevention: Engine oil can form a sealing ring between the piston rings and the piston, reducing gas leakage and preventing external contaminants from entering. Rust and corrosion prevention: Lubricating oil can adhere to the surfaces of components, preventing contact with water, air, acidic substances, and harmful gases. Shock absorption and cushioning: When the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston skirt, connecting rod, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. Lubrication and wear reduction: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing shells. To prevent excessive wear of components, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding components, thereby reducing wear.

Will there be a fine for overdue driver's license renewal?

Generally, there is no penalty for overdue renewal of a driver's license. However, if you continue to drive a motor vehicle without an annual review of an overdue driver's license, you will be subject to corresponding fines. Fines imposed: The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" stipulates: Article 95, if a motor vehicle driver commits any of the following acts, the traffic management department of the public security organ shall impose a fine. Circumstances for imposing fines: During the period when the motor vehicle driver's license is legally seized, detained, or temporarily suspended, the driver uses concealment or deception to reapply for a motor vehicle driver's license. Circumstances for revoking the motor vehicle driver's license: If the physical condition of the motor vehicle driver changes and is no longer suitable for driving a motor vehicle, but the driver continues to drive; or if the driver fails to participate in the annual review on time and continues to drive; or if the driver falls under any of the circumstances specified in the first or second item of the first paragraph, the traffic management department of the public security organ shall revoke the motor vehicle driver's license.

What Causes a Car to Emit White Smoke?

There are several reasons why a car may emit white smoke, including issues with the air filter. When the car's air filter becomes clogged and air intake is insufficient, white smoke may appear from the exhaust pipe. Below are the specific causes and solutions: Specific causes: Malfunction of the carburetor; problems with the oxygen sensor in the exhaust pipe, causing the sensor to fail to provide correct information; too much water in the gasoline. Replacing piston rings: If the engine runs unevenly, it could be due to wear in the engine cylinder's gasket, creating a gap that allows a large amount of water from the cooling system to enter the combustion chamber. If the smoke increases with acceleration and is accompanied by a pungent odor, this indicates an engine malfunction, and the piston rings need to be replaced.

What grade of gasoline should a Mustang use?

Mustang should use 92-octane gasoline, as this fuel grade is recommended in the vehicle's official owner's manual. In addition to checking the suitable gasoline grade in the owner's manual, you can also find it marked on the fuel tank cap. Typically, the fuel grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, those between 10.0-11.5 should use 95-octane gasoline, and if the compression ratio is higher, 98-octane gasoline should be used. However, with the use of some new technologies, the fuel grade cannot be solely determined by the compression ratio. A high compression ratio can also be adjusted to use lower-grade gasoline because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number, and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If a Mustang occasionally uses the wrong gasoline grade, simply switch back to the correct grade after using it up. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower-grade gasoline, using higher-grade gasoline will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use higher-grade gasoline, using lower-grade gasoline can cause engine knocking. Because the octane number is too low, the fuel's ignition point decreases and may ignite prematurely during the compression stroke. If combustion occurs before the spark plug fires during the compression stroke, resistance will arise during the upward stroke. This resistance can make the engine run very unstably. If the knocking is imperceptible, it only increases noise and does not significantly damage the engine. However, if the knocking is noticeable, it indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on the pistons and cylinders, and in severe cases, cylinder scoring.
