National V represents the China 5 emission standard. Below are the relevant details: 1. Introduction: The China 5 emission standard is equivalent to the Euro 5 standard. Europe officially implemented the latest Euro 5 standard starting from September 1, 2009. In 2012, Beijing planned to implement the China 5 standard. Once Beijing fully adopted the China 5 emission standard, it meant that vehicle models failing to meet this standard could not be sold in Beijing. Previously, to control vehicle pollution, Beijing had consistently implemented national standards ahead of schedule. 2. Differences: Compared to the China 4 standard, the new standard reduces nitrogen oxide emissions by 25% for light-duty vehicles and by 43% for heavy-duty vehicles. Based on Shanghai's annual vehicle registration volume of approximately 350,000 units, it is estimated that annual new vehicles could reduce nitrogen oxide emissions by about 1,000 tons. Additionally, the domestic China 5 emission standard's control level is equivalent to the currently implemented Euro 5 emission standard in Europe.

How to Turn Off Car Lights Without Turning Off the Engine at Night?

To turn off the car lights, simply rotate the light control knob to the "OFF" position (some models use "O" for the off position). For some models with a button, pressing it will turn off the lights. Others may have the control on the light lever, where rotating the lever will turn off the lights. Here are some additional details: 1. Some models do not have headlight height adjustment: In certain cars, the automatic headlight switch is located on the light lever. German and American cars typically have their light control adjustment area set on the lower left side of the steering wheel, while Japanese, Korean, and domestic models usually concentrate the light controls on the turn signal lever. 2. Light control on the lever is adjusted by rotating or toggling: Light usage is a mandatory test item in driving exams with a 0% error tolerance, highlighting its importance. If you're unsure about the function corresponding to a particular symbol, try turning it on when the vehicle is stationary to see what function or light it activates. After all, practice is the sole criterion for testing truth.

How often are traffic restriction photos taken?

Traffic restriction enforcement follows a 4-hour cycle where continuous photo captures within this period count as a single violation, with each subsequent 4-hour interval adding another infraction. Within these 4 hours, drivers can move their vehicles out of the restricted zone, park at the nearest lot, or return to their origin without fear of repeat penalties. However, continuous travel within the same day will result in consecutive fines. Key details about tail-number restrictions are as follows: 1. Tail-number restriction system: This traffic management measure, designed to alleviate urban congestion, permits only private vehicles with license plates ending in odd numbers on odd dates and even numbers on even dates to operate. Implementation has proven effective in reducing traffic pressure. 2. Updated enforcement systems: Traffic authorities have upgraded electronic monitoring and on-site officer systems to enable consecutive documentation and penalization of violations. Note that 'consecutive' doesn't mean uninterrupted - vehicles that inadvertently violate restrictions due to forgetfulness receive a 3-hour grace period after initial penalty to exit restricted areas, park nearby, or return home without secondary penalties from either electronic systems or officers. However, deliberate repeated violations within a day will incur sequential fines. Regardless of violation frequency, each day carries only one penalty of 100 RMB fine (no point deduction).

What is the purpose of a child safety seat?

Child safety seats can effectively improve children's safety during car rides by reducing the impact force on children and limiting their body movement in the event of a car collision or sudden deceleration. Here is relevant information about child safety seats: 1. Laws and regulations: In China, the "National Mandatory Standard for Child Safety Seats and Related Products" drafted by the China Automotive Technology and Research Center officially came into effect on July 1, 2012. This standard includes technical requirements for the seats themselves and mandates that all vehicles on sale must be equipped with ISOFIX anchor systems. 2. Maintenance: After removing the fabric cover, hand wash it with laundry detergent or baby-specific clothing cleaner and let it air dry naturally.

Why Should a New Battery Be Fully Discharged for the First Time?

For electric vehicles, it is not necessary to fully discharge a new battery for the first time. The maintenance methods for batteries are introduced as follows: 1. Batteries should not be charged at any time: Lead-acid batteries are not lithium batteries and cannot be charged immediately after use. The lifespan of a lead-acid battery is calculated based on the number of charge and discharge cycles. The battery is most afraid of being depleted, and keeping it fully charged can extend its lifespan. 2. During charging: The charger's indicator light turns red first and then green. After the light turns green, it is recommended to maintain a float charge for 2 hours, which helps inhibit battery sulfation. 3. Prevent overcharging the battery: Overcharging generates a large amount of gas that scours the plates, accelerating the shedding of active material from the plates and shortening the battery's lifespan. Overcharging also accelerates water loss, leading to drying of the electrolyte, an increase in battery temperature, thermal runaway, plate expansion, and casing deformation. 4. Prevent over-discharging the battery: Long-term deep discharge can cause softening of the battery plates, reducing their service life. Avoid high-current discharge; when starting, climbing hills, or driving against the wind, try to use pedal assistance. Avoid prolonged discharge and do not frequently drive until the battery is fully depleted. Charge the battery when its capacity drops by half.

Is Parking on a Slope Harmful to the Car?

Parking on a slope definitely causes some harm to the car. When parked on a slope, the car is subjected to the component of its own weight along the slope, and this force is mainly borne by the handbrake. The handbrake cable, being in a taut state for a long time, will gradually stretch, and the suspension will bear pressure. This reduces the reliability of the handbrake, making issues like the car not staying parked and rolling backward increasingly apparent. Impact on the suspension: When parking on a slope, the side facing downhill bears greater pressure on the suspension. Over time, this causes uneven aging and varying stiffness between the front and rear suspensions, affecting ride comfort. Damage to the handbrake braking system: Parking the car on a slope means the handbrake has to bear the pressure. The handbrake fixes the vehicle by pulling the brake via a cable. When parked on a slope, the handbrake cable continuously bears the component of the car's weight parallel to the slope. Prolonged exposure to this stress can fatigue the handbrake cable, affecting its performance. Risk of rolling: If parked on a slope for an extended period, the handbrake may age and fail at any time, leading to the possibility of the car rolling away.

Is a Car with Cut Rear Fender Considered an Accident Vehicle?

A car with a cut and replaced rear fender is considered a major accident vehicle. If the rear fender has undergone cutting and replacement, it falls under the category of an accident vehicle. However, if it only underwent panel beating repairs without any cutting or welding, it is not classified as an accident vehicle. Introduction to Accident Vehicles: An accident vehicle refers to a car that has suffered damage due to non-natural wear and tear, leading to a decline in mechanical performance and economic value. Generally, these are vehicles with structural damage, where the performance is inferior to its original state. An accident inherently indicates issues with the car, and driving such a vehicle may pose safety hazards. Accident Vehicle Inspection: Methods include exterior inspection, light inspection, insurance record check, and interior examination. When purchasing a used car, it is essential to carefully observe aspects such as the manufacturing date, actual mileage, whether the car has been involved in any major accidents, and the level of daily maintenance provided by the previous owner.
