Reasons for a strong gasoline smell in the car: 1. The gasket inside the fuel tank cap is aged or uneven; 2. Long-term accumulation of dirt on the fuel injector and throttle body, leading to incomplete combustion of gasoline; 3. The gasoline filter is dirty or the connecting hose fittings are loose and aged; 4. The gasoline vapor canister is dirty or malfunctioning; 5. The fuel tank connecting hose is aged and loose; 6. Poor sealing performance of the car. When the vent hole is blocked, the evaporated fuel vapor cannot be released and will escape elsewhere, causing a gasoline smell in the cabin. Therefore, when there is a gasoline smell in the car, you can use compressed air to blow through the vent hole to resolve the issue.

Reasons for the sudden blackout of the instrument panel during normal driving?

Possible faults in the instrument panel circuit or poor grounding of the vehicle body may cause this phenomenon. It is recommended to contact a 4S shop for inspection and repair. Precautions for instrument panel maintenance are as follows: 1. Avoid direct exposure to ultraviolet rays to prevent the instrument panel from fading, aging, cracking, wrinkling, etc. More importantly, it protects the precision and normal use of the instrument. 2. The instrument panel can be maintained with dashboard wax. Spray and wipe to clean, polish, and protect in one step, enhancing gloss and forming a bright and clean protective film on its surface to beautify and restore natural colors. 3. It also has anti-static functions, UV resistance, waterproofing, anti-mold, etc., reducing dust accumulation, thereby effectively extending the service life of the instrument panel.

Are there any dress code requirements for the Subject 1 exam?

There are no specific dress code requirements for the Subject 1 exam. However, since the computer in the theoretical exam room is equipped with a camera, it is recommended not to wear accessories such as hats and sunglasses that may obscure facial features. If wearing items like hats, masks, or scarves that cover the face, you may enter the exam room after removing them. Subject 1 exam precautions: Candidates should pay attention to their attire during the exam. Wearing slippers is not allowed, and electronic devices and bags are prohibited in the exam room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures displayed on the large screen, and store personal belongings in the locker before entering the exam room. Upon entering the exam room, the identity verification desk will assign a seat. After finding your seat, begin the exam. Ensure the camera is aligned with you and follow exam discipline. If you fail the first attempt, a free retake is available on the same day. If you fail again, you must pay and reschedule. After completion, queue to collect your score report and sign it. Failure to sign will render the result invalid. The "Regulations on the Application and Use of Motor Vehicle Driving Licenses" clearly stipulate that the Subject 1 exam can be taken twice on the same day. If you fail the first attempt, a free retake is available for the second attempt. If you fail the second attempt, the Subject 1 exam is terminated, and you must wait ten days before rescheduling. Subject 1, also known as the theoretical exam or driver's theory test, is part of the motor vehicle driving license assessment. The exam content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The Subject 1 exam consists of 100 questions, divided into single-choice and true/false questions, each worth 1 point, totaling 100 points. If you answer 11 questions incorrectly, the system will automatically submit the exam and end the test. The Subject 1 exam is computer-based and has a time limit of 45 minutes. Subject 1 exam content: Driving license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. There is no limit to the number of times you can reschedule the Subject 1 exam. Each subject can be taken once, with one retake allowed if you fail. If you do not take the retake or fail the retake, the exam is terminated, and you must reschedule. In contrast, Subject 2 and Subject 3 allow only five exam attempts, and rescheduling must occur ten days later. If you fail the Subject 3 safe driving knowledge test, the previously passed road driving skills test results remain valid. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the exam on road traffic safety laws, regulations, and related knowledge; Subject 2 refers to the field driving skills exam; Subject 3 is divided into two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official term (as per the Ministry of Public Security Order No. 123) does not include Subject 4.

Should I Shift Gears and Apply Brakes When Reversing into a Parking Space?

It is best to keep the brake pedal pressed continuously. If you can ensure that the test vehicle does not roll while in the garage, you may not need to press the brake. When shifting gears, the vehicle is required to be in a stationary state; if rolling occurs, it may result in a failed assessment. Below are detailed explanations of the automatic transmission gear positions: 1. R (Reverse) Gear: Engaging this gear connects the hydraulic system to the reverse oil circuit, causing the drive wheels to rotate in reverse for backward movement. 2. N (Neutral) Gear: When in neutral, the planetary gear system idles and cannot output power. 3. D (Drive) Gear: When the gear selector is in this position, the hydraulic control system automatically connects the corresponding forward gear oil circuit based on throttle opening and vehicle speed signals. It can automatically shift up or down according to driving speed changes, achieving automatic transmission functionality.

Does a vehicle need inspection if it can drive normally without stalling after wading through water?

If the car did not stall after wading through water, it should be fine. However, if the water depth exceeded half of the tire height, it may endanger the vehicle's electrical systems and the onboard computer, so it's best to conduct an inspection. The hazards of water-damaged vehicles include the following two points: 1. Interior impact: Prolonged soaking can cause deformation, roughness, and odor in materials such as carpets and seats, leading to bacterial growth. Moisture under the carpets can result in short circuits in the wiring harness due to dampness. These soaked components are best replaced to avoid long-term water damage effects. 2. Door panel impact: The door panels contain soundproofing material, which needs replacement after water exposure. The wheel bearings must also be replaced because their seals contain lubricating grease. If not replaced, the grease can corrode and deteriorate, losing its lubricating properties and compromising driving safety.

How to Calculate Vehicle Tax in 2021?

In the new regulations on vehicle purchase tax, the tax rate is 10%. The calculation formula for vehicle purchase tax in 2021 is: Taxable amount of vehicle purchase tax = Taxable price of the vehicle × Tax rate. It should be noted that the VAT rate is 17%, and the purchase price in the special invoice for motor vehicle sales includes VAT. Therefore, when calculating the vehicle purchase tax, the 17% VAT must be deducted first. The following are the precautions for vehicle registration: 1. Vehicle certificate is required for registration: When registering the vehicle at the vehicle management office, the vehicle certificate needs to be submitted to the staff for archiving. 2. Purchase invoice is required for registration: Whether you buy a car from a 4S store or an auto trade company, you will receive a purchase invoice after the purchase. This invoice must be kept properly, as without it, the vehicle cannot be registered. When registering the vehicle, the purchase invoice must be submitted to the vehicle management office staff for archiving.

How Often Should the CVT Transmission Fluid Be Changed for RAV4 Rongfang?

It is generally recommended to change it every 80,000 kilometers. Transmission fluid is an oil product that keeps the shifting system clean, lubricates to prolong the life of the transmission components, and provides effective lubrication even in low-temperature conditions, reducing oil loss under harsh operating conditions. The details are as follows: 1. When changing the fluid, it is essential to use the manufacturer-specified automatic transmission fluid: This is because different automatic transmissions have varying internal structures, friction components, and sealing components. The original manufacturer's fluid is specially formulated based on the transmission's structure and materials, and other brands of fluid, even if of high quality, may not be suitable. 2. Some old fluid may remain during the change: When changing the transmission fluid, some old fluid may remain in the transmission channels and torque converter. Mixing different fluids inside the automatic transmission may degrade the performance of the transmission fluid, leading to poor lubrication or operational abnormalities, which can severely damage the automatic transmission.
