First, inspect the outer packaging to see if there are any scratches or dents. When purchasing a battery, the initial step is to check whether the outer packaging of the electric vehicle battery is damaged or shows signs of being opened. Next, carefully examine the metal terminals at the positive and negative ends of the battery for any signs of rust. Finally, check if there is an anti-counterfeiting label on the battery. Firstly, it enhances the driver's sense of control, significantly reduces the vehicle's fuel consumption, and also improves steering responsiveness, enhances steering return characteristics, and increases the vehicle's stability and safety.

What is the fuel tank capacity of the Jetta in liters?

The fuel tank capacity of the Jetta is 51L. The vehicle features a turbocharged intake system, a manual-automatic transmission, front-wheel drive, a front MacPherson independent suspension, and a rear multi-link independent suspension. Among vehicles in the same class, the Tiggo 8 has a fuel tank capacity of 51L, the Roewe RX5 has a capacity of 55L, and the Beijing Hyundai has a capacity of 58L. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety level, with additional space from the safety level to the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is added up to the tank opening during refueling, the actual amount of fuel may exceed the calibrated capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the instrument panel, marked with E and F. When the needle is near E, it indicates low fuel, and when it is close to F, it indicates sufficient fuel.

Under What Circumstances Do Auto Insurance Companies Deny Claims

Auto insurance companies deny claims under the following circumstances: 1. Violation of traffic rules: Driving under the influence, driving without a license, or driving with an un-inspected vehicle registration or driver's license will result in denied claims. In these situations, the driver does not have the legal right to operate a vehicle and is in serious violation of traffic laws. Additionally, insurance companies will refuse to pay if the driver's license does not match the vehicle type or if the driver is in the probationary period and drives on highways. 2. Earthquake damage: Following the common practice of most property insurance policies not covering earthquake damage, insurance companies are discouraged from providing such coverage due to lack of data and experience, as per insurance regulatory authorities. 3. Emotional distress: Most insurance policies have similar clauses stating that any emotional distress claims arising from an insured incident are excluded from coverage. 4. Losses during vehicle repair: Repair shops are responsible for the safekeeping of vehicles under repair. Therefore, any damages such as collisions or theft that occur while the vehicle is in the shop will not be covered by the insurance company.

How early can I renew my driver's license?

The renewal can only be done up to 90 days in advance. According to Article 57 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": A motor vehicle driver shall apply for renewal at the vehicle management office of the place where the driver's license was issued or at a vehicle management office outside the place of issuance within 90 days before the expiration of the motor vehicle driver's license. The following are the precautions for renewing a driver's license: 1. Provide relevant documents: The identity proof of the motor vehicle driver and the motor vehicle driver's license; a medical certificate issued by a county-level or above medical institution or a military medical institution at the regimental level or above. 2. Driving during the renewal period: If you continue to drive a motor vehicle on the road after the expiration of your driver's license without renewal or after it has been revoked, you may face a fine ranging from 200 to 2,000 yuan or even administrative detention for up to 15 days, depending on the severity of the violation, if caught by traffic authorities. In the event of a major traffic accident resulting in personal injury or death, criminal liability will be pursued according to the law.

Why does the car engine shake and the malfunction indicator light come on?

The reasons for the car engine shaking and the malfunction indicator light coming on are as follows: 1. Poor quality gasoline that does not meet standards: This is usually caused by refueling with low-quality gasoline at non-standard gas stations, leading to insufficient combustion of the air-fuel mixture during engine operation and the illumination of the engine malfunction light. This does not affect driving safety but may more or less harm the engine. 2. Oxygen sensor malfunction: Modern cars are equipped with two oxygen sensors, one before and one after the three-way catalytic converter. The front oxygen sensor detects the air-fuel ratio under different engine operating conditions, while the ECU adjusts the fuel injection quantity and calculates the ignition timing based on this signal. The rear sensor mainly monitors the performance of the three-way catalytic converter. Therefore, if the oxygen sensor is damaged or the sensor connector is damaged or loose, it can cause the air-fuel mixture to be too lean or too rich, triggering the malfunction light.

What to Do When Diesel Vehicles Have Difficulty Starting in Winter?

Diesel vehicles starting methods in winter are as follows: 1. Preheating should be done in low-temperature seasons: The main reason affecting the starting performance of diesel engines during cold starts is the inability to reach the compression ignition temperature of diesel. To address this, adding hot water to the engine cooling system for preheating is an effective way to improve starting performance. 2. Improve the sealing performance of the cylinders: One of the differences between diesel engines and gasoline engines is the compression ignition method, which requires higher sealing performance in the cylinders. During cold starts in summer, due to the lack of oil between the piston rings and cylinder walls, the sealing effect is poor, leading to repeated starting attempts without successful ignition. Sometimes, severe cylinder wear significantly affects the sealing performance, making starting even more difficult. To address this, the injectors can be removed, and 30-40ml of oil can be added to each cylinder to enhance the sealing performance.
