What to Do When a Keyless Start Car Cannot Detect the Key?

How long should you keep the car running after jump-starting a dead battery before turning it off?

After jump-starting a dead battery, the car should run for at least one hour before being turned off. Make sure to turn off all electrical devices before shutting down the engine. If a car battery remains unused for a long time, it will slowly discharge on its own and eventually become unusable. Therefore, it is recommended to start the car periodically to recharge the battery. Here are some methods to deal with a dead battery: 1. Push-start method: Push-starting is the most effective emergency starting method, but it should not be used frequently. This method can cause some damage to the engine and clutch, especially in automatic transmission vehicles, which should avoid using this method. 2. Jumper cable method: Connect the positive terminal of the dead battery to the positive terminal of the rescue car's battery, then connect the negative terminal of the rescue car's battery to a metal part of the dead car's engine (ground wire). Be careful not to reverse the order of the jumper cable connections. After connecting the jumper cables, start the rescue car's engine and slightly increase its RPM. After about 5 minutes, the dead battery will receive an emergency charge. Once charging is complete, disconnect the jumper cables in the reverse order of their connection.

Is It a Violation to Run a Red Light Behind a Large Vehicle?

In general, if a motor vehicle is photographed running a red light behind a large vehicle, it is usually because the driver tried to rush through the intersection when the signal was changing. This behavior can only be penalized as running a red light. However, if it is confirmed that the driver could not see the traffic signal due to the obstruction of the large vehicle, they can apply for reconsideration after being penalized. Drivers should maintain sufficient visibility to see the traffic signals ahead and ensure a safe braking distance. Penalty points for running a red light: According to Article 2, Clause 1, Subclause 2 of the "Scoring Standards for Road Traffic Violations," driving a motor vehicle in violation of traffic signal lights will result in a deduction of 6 points. Article 3, Clause 1, Subclause 8 states that driving a motor vehicle in violation of prohibitory signs or markings will result in a deduction of 3 points. How to check for red-light violations: You can check for red-light violations through the "Traffic Management 12123" app. After opening the app, log in with your ID card, find the option for violation handling, and click on it. In the violation handling section, you can see the current status of your vehicle. If there is a violation, the specific details will be displayed. You can also check by visiting the service halls of the traffic police departments in various cities and districts and using the touch query terminals. Alternatively, log in to the external service websites of the public security traffic management bureaus of various cities: find the vehicle violation query section, enter your license plate number and vehicle engine number, and click to query.

Why Does the Windshield Crack by Itself?

Here are the specific reasons why windshields crack by themselves: 1. Heating and cooling during the laminated glass manufacturing process: Windshield cracks usually occur at the edges of the glass, primarily due to the heating and cooling process during laminated glass manufacturing. This process creates internal tensile stress and surface compressive stress in the glass. The glass remains stable when these forces are in balance, but if not, it may crack spontaneously. 2. Exposure to cold water after being in the sun: If car glass is exposed to cold water after being in the sun, the extreme temperature change may also cause the glass to crack. 3. Recommended actions: If the windshield cracks by itself, pull over immediately and do not continue driving. For safety reasons, it is recommended to replace the windshield directly.

When is the implementation time of China VI emission standards in Shandong?

The "China VI standard" is divided into two phases: "China VI a" and "China VI b," and is planned to be uniformly implemented nationwide in 2020 and 2023, respectively. The implementation of China VI emission standards in Shandong also follows a two-step approach. China VI a was implemented starting from July 1, 2019, and from this date, the registration of China V vehicles was also halted. China VI b will be implemented starting from July 1, 2023, at which point the registration of China VI a vehicles will be restricted. More information about China VI is as follows: 1. The two standards of China VI: Namely, China VI A and China VI B. China VI A can be seen as a transitional phase from China V to China VI, with lower emission requirements compared to China VI B. Therefore, China VI B is the complete and true China VI standard. 2. During the implementation of China VI: There will be at least a one-month transition period after the implementation of China VI. For vehicles purchased before July 1, 2020 (excluding July 1, based on the date of the purchase invoice) or transferred from other provinces or cities into Shandong (based on the transfer registration date on the vehicle registration certificate) that meet the China V emission standards, the traffic management department of the public security organ can process vehicle registration procedures within one month after the implementation date specified in this notice. Registration will not be processed after the deadline.

What causes excessive carbon monoxide in car exhaust?

Excessive carbon monoxide levels are usually caused by a faulty catalytic converter leading to emission exceedance. Common reasons for high carbon monoxide include: 1. Carbon deposits: Caused by carbon buildup and coking (excessive throttle valve opening, oversized spark plug gaps, excessive intake system carbon deposits, etc.). 2. Oxygen sensor: If emission tests show exceedance, first check the oxygen sensor's working status with a diagnostic tool (oxygen sensors activate only when engine temperature exceeds 90°C). A faulty oxygen sensor may cause nitrogen oxide exceedance; oversized spark plug gaps lead to carbon monoxide exceedance; excessive carbon deposits result in hydrocarbon value exceedance.

What is the difference between 3st and 4st tires?

The differences between 3st and 4st tires are as follows: 1. Different drainage performance: 4st features a new tread design through Evergrip technology, increasing drainage space by over 50% compared to 3st, providing excellent drainage and reducing hydroplaning. 2. Different rubber compound: Compared to 3st, 4st adopts a new tread design and rubber compound, improving wet braking performance and rolling resistance for both new and worn tires. 3. Different safety performance: Due to the new rubber compound, 4st offers superior braking performance, making the brakes more effective, thereby enhancing driving safety to a certain extent.
