Sleeping in a car with the air conditioning on can lead to carbon monoxide poisoning. Here are the relevant details: 1. Carbon monoxide production: When the engine idles for a long time, incomplete combustion of gasoline produces high concentrations of carbon monoxide, which can enter the car and poison the passengers. 2. Poor air circulation: The car is in a closed state, preventing the produced carbon monoxide from being expelled. 3. Precautions: Avoid letting the engine idle for extended periods. When the car is parked: Do not keep the air conditioning on for too long; even while driving, frequently open the windows to allow air exchange between the inside and outside of the car. Stop and rest if feeling unwell: If you or passengers feel dizzy, sluggish, or weak while driving or riding in an air-conditioned car, open the windows immediately to breathe fresh air. After entering the car: First, open the windows for ventilation. After the car has been exposed to the sun, do not start the engine immediately upon entering. Instead, open all four doors to ventilate and disperse toxic gases.

What to Do If 6 Points Are Deducted During the Probationary Period of a Driving License?

If 6 points are deducted from a C1 driving license during the probationary period, it will not affect the driving license, nor will it extend the probationary period. Just pay the fine and deduct the points as usual. However, if more than 12 points (including 12 points) are deducted during the probationary period, the driving license will be revoked, and you will need to directly register at the vehicle management office to participate in learning and exams. For drivers holding licenses for large buses, tractors, city buses, medium-sized buses, or large trucks, if 6 or more points (but less than 12 points) are deducted during the one-year probationary period, the probationary period will be extended by one year. If another 6 or more points (but less than 12 points) are deducted during the extended probationary period, the driving qualification for the probationary vehicle type will be revoked. Probationary Period Regulations for Driving Licenses: A probationary sign must be displayed. Article 22 of the "Regulations for the Implementation of the Road Traffic Safety Law" stipulates: The validity period of a motor vehicle driving license is 6 years. The first 12 months after a motor vehicle driver initially obtains a driving license is the probationary period. During the probationary period, a uniform probationary sign must be affixed or hung at the rear of the vehicle when driving. Failure to affix or hang the probationary sign as required will result in a fine of 200 yuan.

How many points will be deducted for parking in a no-parking zone?

Illegally parking in a no-parking zone will result in a 3-point deduction and a fine. No-parking zones generally do not offer any grace period, and whether parking is considered illegal largely depends on the judgment of traffic police. In areas with high temporary parking demand, such as near schools, hospitals, or commercial establishments, there may be policies allowing parking within specified time frames. Otherwise, in no-parking zones, even stopping for one second constitutes illegal parking. If it is a no-parking zone: Typically, no-parking signs are placed at the entrances and exits of intersections. There are two types of no-parking signs: one with a red slash and the other with a red cross. A red slash indicates that vehicles cannot park for extended periods—in simple terms, you can stop but should not turn off the engine or leave the vehicle. If approached by traffic police, follow their instructions to move away. A red cross means vehicles cannot park, even temporarily—stopping for even one second is considered illegal parking. Additionally, some cities have regulations allowing drivers to avoid penalties if they leave within a specified time after an illegal parking violation: For example, in Chengdu, for temporary parking violations, traffic police will send a reminder message to the vehicle owner, urging the driver to correct the violation promptly. If the driver voluntarily leaves within 10 minutes, no penalty will be imposed. However, if the violation is not corrected within the allotted time, penalties will be enforced according to the law. Therefore, when parking on the roadside, even if there are no no-parking signs or markings, always park in designated parking lots or spaces to avoid fines.

What to Do When the Engine Warning Light Comes On in a Nissan Sylphy?

When the engine warning light comes on, you can follow these steps to address the issue: First, check whether the engine is running normally. Look for signs such as shaking, black smoke emission, or difficulty starting. If any of these issues are present, avoid restarting the engine. Note: If the red warning light is on, do not attempt to restart the engine under any circumstances. If the engine is running normally and the vehicle can be driven, proceed to a service center as soon as possible to diagnose the issue. A service center can easily read the fault codes using a portable diagnostic tool, allowing for targeted repairs based on the fault information. If the engine is running normally, the owner can also try gently reconnecting various wiring harness connectors, as a loose connection might be the cause. Alternatively, repeatedly turning the key to the ON position may help reset the system. Generally, the engine warning light may come on due to the following seven reasons: Sensor malfunction: This includes sensors such as the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, and oxygen sensor. If these sensors are damaged, have poor contact, or lose signal transmission, the vehicle's ECU cannot accurately obtain engine data, triggering the warning light. Fuel or oil quality issues: Failure to use the fuel or oil specified by the manufacturer may cause engine wear, leading to the warning light activation. Poor combustion of the air-fuel mixture: Incomplete combustion can cause engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate. Issues such as faulty spark plugs, defective ignition coils, fuel pump failure, or clogged fuel lines can lead to poor combustion. Turbocharger issues: Problems with the intake boost system or turbocharger can also trigger the warning light. The most common issue is turbocharger damage, often accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake system issues: Blockages in the engine intake system can cause the warning light to come on. A dirty or uncleaned air filter can lead to intake problems. Exhaust system issues: Exhaust-related faults can also trigger the warning light. Common causes include faulty rear oxygen sensors, catalytic converter issues, or problems with the exhaust camshaft and bearings. The catalytic converter is particularly prone to failure due to the use of leaded gasoline, lead- or silicon-based lubricant additives, physical damage, or fuel system malfunctions. Anti-theft system malfunction: If the vehicle's electronic anti-theft system fails or the anti-theft controller is incompatible with the engine ECU, the engine may not function properly, and the warning light will illuminate.

What are the reasons for the Lavida's engine shaking and the engine fault light coming on?

There are mainly 7 reasons for the Lavida's engine fault light coming on: Sensor failure: The sensors mentioned here include the water temperature sensor, crankshaft position sensor, air flow sensor, intake temperature sensor, oxygen sensor, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine fault light to come on. Fuel quality issues: If fuel and engine oil are not added according to the manufacturer's requirements, it may cause engine wear and trigger the fault light. Poor combustion of the air-fuel mixture: Poor combustion of the air-fuel mixture can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the fault light will illuminate as a warning. Issues such as spark plug failure, ignition coil failure, fuel pump failure, or fuel line blockage can all cause poor combustion of the air-fuel mixture. Turbocharging issues: The intake turbocharging pipeline and turbocharger can also cause the engine fault light to come on. The most common issue is turbocharger damage, accompanied by symptoms such as oil leakage, high oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust pipe. Intake issues: If the car's intake system has problems, it may cause engine pipeline blockage, and in severe cases, trigger the engine fault light. A dirty air filter that is not cleaned regularly can lead to intake problems. Exhaust issues: Exhaust faults can also cause the engine fault light to come on. The rear oxygen sensor, catalytic converter, exhaust camshaft, and bearing failures are all potential causes of exhaust problems, with the catalytic converter being the most common. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel supply system failures can easily lead to catalytic converter issues. Anti-theft system failure: If the car's electronic anti-theft system malfunctions or the anti-theft controller does not match the engine electronic controller, the anti-theft system can prevent the engine from operating normally and trigger the engine fault light. If the engine fault light comes on, follow these steps: First, check if the engine is running normally, whether there is shaking, black smoke, etc. If so, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can be started, turn it off for 5-10 minutes, then without pressing the brake, press the start button once or turn the key halfway to the 'on' position without depressing the clutch. The car will perform a self-check after powering on. Wait 5-10 seconds to see if the fault light on the dashboard turns off. If the fault light remains on, visit a service station as soon as possible. The service station can use a portable diagnostic tool to read the fault codes, identify the issue, and perform targeted repairs.
