What does the P indicator on the car mean?

When the dashboard displays a P, it indicates that the parking brake is engaged. The parking brake, commonly referred to as the handbrake, is a manually operated brake installed in motor vehicles. It is used to stabilize the vehicle after it has come to a complete stop, preventing accidents caused by rolling on inclined surfaces. Here is a detailed introduction to the parking brake: Working principle of the parking brake: Mechanical handbrakes operate via a cable or similar mechanism that connects to the rear brake calipers. When the handbrake is engaged, the calipers press against the brake pads, thereby achieving the parking function. Electronic handbrakes, on the other hand, use an electric motor to drive the cable or similar mechanism, which then engages the rear brake calipers to press the brake pads and achieve the parking function when the parking switch is activated. Parking brakes can be categorized by operation method into two types: Hand-operated parking brakes and foot-operated parking brakes. By control method, they are divided into two types: mechanically controlled parking brakes and electronically controlled parking brakes. To engage the parking brake, press the brake pedal down and fully pull out the parking brake lever. To release the parking brake, press the brake pedal down, slightly pull the parking brake lever upward, press the button on the handle end with your thumb, and then lower the parking brake lever back to its original position.

How Many Kilograms Does 1 Liter of Gasoline Equal?

According to the density of each substance, 1 liter of gasoline is approximately equal to 0.72~0.75 kilograms. Because according to the measurement units, 1 kilogram equals 1 kilogram. So we convert 1 liter to 1000 milliliters for calculation. The density of commonly used 92-octane gasoline in daily life is about 0.725g/ml, while 95-octane gasoline is 0.737g/ml. The calculation shows that 1 liter of 92-octane gasoline is approximately 0.725 kilograms, and 1 liter of 95-octane gasoline is about 0.737 kilograms. The mass density formula m=V can be used to determine how many kilograms 1 liter of gasoline equals. Gasoline density: The average density of 90-octane gasoline is 0.72g/ml, so the mass of 1 liter of 90-octane gasoline is 0.72 kilograms. The density of 93-octane gasoline is 0.725g/ml, so the mass of 1 liter of 93-octane gasoline is 0.725 kilograms. The density of 97-octane gasoline is 0.737g/ml, so the mass of 1 liter of 97-octane gasoline is 0.737 kilograms.

What to Do When Your Driver's License Accumulates 12 Points?

If your driver's license accumulates 12 points, you must attend a seven-day study session on road traffic safety laws and regulations, followed by the subject one exam. Upon passing the exam, the points will be cleared, and your driver's license will be returned. If you fail the exam, you will need to retake the study session and the exam. Legal Basis: Article 24 of the Road Traffic Safety Law states that the traffic management department of the public security authority shall implement a cumulative point system for motor vehicle drivers who violate road traffic safety laws and regulations, in addition to imposing administrative penalties in accordance with the law. For motor vehicle drivers whose cumulative points reach the prescribed value, the traffic management department of the public security authority shall detain their driver's license and provide education on road traffic safety laws and regulations, requiring them to retake the exam. Passing the Exam: If you pass the exam, your driver's license will be returned. For motor vehicle drivers who comply with road traffic safety laws and regulations and have no accumulated points within one year, the validity period of their driver's license may be extended. The specific measures shall be stipulated by the public security department under the State Council.

Are there discounts for ETC toll fees?

There are discounts for using ETC toll fees, and banks handling related applications offer greater incentives to encourage ETC adoption. Starting from 2020, vehicles without ETC or not using ETC cannot enjoy toll discounts. In the future, highway toll stations will retain only one manual lane, requiring payment through manual channels, with lower efficiency compared to ETC lanes. ETC charging principle: Highways will have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane, combined with computer networking technology for backend bank settlements, vehicles can pay tolls without stopping at toll stations. This is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of queuing and waiting. Green and eco-friendly: Promotes low-carbon travel by reducing noise and exhaust emissions as vehicles pass toll stations without stopping. Reduced wear and tear: Saves costs by minimizing vehicle acceleration and braking frequency, lowering wear and fuel consumption. Improved efficiency: ETC lanes can theoretically increase vehicle throughput by 2-3 times, making traditional ETC faster and more advanced. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" the goal of "achieving interoperability of transportation cards in key city clusters by 2020 and significantly increasing the proportion of vehicles equipped with ETC." It also set the target of "50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of comprehensive transportation development during the 13th Five-Year Plan. More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, future efforts will promote ETC adoption for trucks and explore deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-road coordination, and other smart transportation directions, providing comprehensive travel services for car owners. This means more application scenarios will support ETC. ETC usage precautions: The ETC transaction sensing range is 8 meters. To avoid paying for the vehicle ahead due to its ETC device malfunction or absence, maintain a distance of over 10 meters from the preceding vehicle. The ETC lane recognition speed is 20 km/h. Excessive speed may prevent reading vehicle device information, leading to failed deductions. Unauthorized removal or movement of the OBU device, or detachment/loosening of the ETC electronic tag, will render the tag invalid. It can be inspected at the bank where the ETC card was issued or at highway service centers. Non-deliberate detachment or loosening only requires reactivation. Insufficient balance in debit cards linked to ETC may cause deduction failures. Follow on-site staff guidance to use manual MTC lanes with cash or card payments. Thick windshields may cause poor signal reception, especially for vehicles with replaced or modified windshields after accidents.

Should You Engage the Handbrake or Shift Gears First When Starting a Car?

For automatic transmission vehicles, you should shift gears first and then release the handbrake when starting. This is the safest operating sequence. Of course, whether you shift gears first or release the handbrake first won't have any impact on the vehicle's transmission components. The purpose of releasing the handbrake last is to prevent the car from rolling. Here are some additional details: Specific steps for starting the car after getting in: Insert the key into the ignition switch, press the brake pedal to start the vehicle, and release the brake pedal after the engine starts. Wait for 1 minute (this can be extended appropriately in winter) to allow the engine to be fully lubricated. During this time, you can fasten your seatbelt, adjust the seat, and check the dashboard for any abnormal warning lights. Ensure the rearview mirrors provide good visibility, and turn on the necessary lights if needed. Then, press the brake pedal, shift into gear, and finally release the handbrake. After ensuring the surrounding environment is safe, you can release the brake pedal and prepare to start driving.
