Is it mandatory to use 95-octane gasoline for the Jetta VS5?

The manufacturer of the Jetta VS5 specifies the use of 95-octane gasoline. Using 95-octane gasoline provides better protection for the Jetta VS5's engine. The type of gasoline to use should follow the manufacturer's requirements, and one should not blindly choose the gasoline grade based on the compression ratio alone. Relevant information about 95-octane gasoline is as follows: 1. 95-octane gasoline consists of 95% isooctane and 3% n-heptane. High-octane gasoline should be used when the engine has a high compression ratio. Using low-octane gasoline in a high-compression engine can lead to abnormal combustion, causing knocking, increased fuel consumption, and reduced driving power. 2. There is no fundamental difference in quality between 92-octane and 95-octane gasoline; neither has issues with fuel impurities. 92-octane gasoline contains 92% isooctane + 8% n-heptane, while 95-octane gasoline contains 95% isooctane + 5% n-heptane.

What to Do When a Wrench Icon Appears on the Dashboard?

Visit a 4S shop for car maintenance and servicing, and the icon will automatically disappear. This wrench is a maintenance reminder indicator, signaling that your vehicle is nearing or has exceeded the recommended maintenance mileage. The method to remove the wrench icon from the dashboard is: 1. Insert the key without turning it. 2. Hold down the lever next to the odometer for 5 to 10 seconds, then turn on the power. 3. After another 5 to 10 seconds, start the car to remove the icon. Other indicator lights on the dashboard include: 1. Seatbelt indicator: Alerts the driver and passengers if seatbelts are not fastened. 2. Oil pressure indicator: Warns the driver of low oil pressure. 3. Door indicator: Alerts the driver if any door is not properly closed.

How Long Does It Take from License Plate Selection to Registration?

After selecting the license plate number and paying the fees, you will typically receive the plate within three to five working days. Below is relevant information about vehicle registration: Documents required for registration: ID card, vehicle certification, triplicate car purchase invoice issued by the 4S store, original and duplicate tax receipts obtained after paying the vehicle purchase tax, insurance policy, compulsory traffic insurance policy, and a temporary residence permit if you are not a local resident. New vehicle registration must be processed at the vehicle management office. After submitting all required documents and paying the fees, the vehicle must be driven to the office for inspection. Some vehicles exempt from inspection only require an external check, which generally involves verifying the engine number and chassis number. After the inspection, you can proceed to the office lobby to select your license plate. Function of license plates: The primary function is to identify the vehicle's region of registration through the plate number, and it also allows tracking of the vehicle's owner and registration details.

What size is a 10R22.5 tire?

10 represents the tire section width of 10 inches (width), 22.5 represents the rim diameter of 22.5 inches, and the letter R in the middle stands for radial tire. Regularly clean the stones in the tire grooves, avoid exposing the tires to direct sunlight, and frequently check the tire pressure. You can refer to the normal tire pressure values listed on the inner side of the car's fuel tank cap and adjust accordingly based on these values. Car tire lifespan: The lifespan of car tires is generally 3-5 years or 50,000-80,000 kilometers. The main material of car tires is rubber, which can age to some extent when exposed to sunlight for extended periods. Long-term outdoor parking can accelerate tire aging, reducing tire strength. Such tires typically last more than three years. Functions of car tires: Support the entire weight of the vehicle, bear the load of the car, transmit traction and braking torque, ensure adhesion between the wheels and the road surface, mitigate and absorb vibrations and impact forces during driving, prevent severe vibrations and premature damage to car components, adapt to the vehicle's high-speed performance while reducing driving noise, and ensure driving safety, handling stability, comfort, and fuel efficiency.

What does TD mean in cars?

TD in cars stands for turbocharging. To address the inherent shortcomings of SDI, a turbocharging device is installed on diesel engines, significantly increasing the intake pressure. The compression ratio generally exceeds 10, allowing for high torque even at low RPMs. Moreover, due to more complete combustion, the content of harmful particles in emissions is also reduced. The TDI-equipped direct-injection turbocharged diesel engine technology is highly advanced and incorporates multiple cutting-edge technologies, such as the pump-jet system and adjustable vane turbochargers, which are applied in passenger cars. TDI utilizes high-pressure fuel injection technology with a pump-jet system. This system ensures better mixing of diesel and air, leading to more thorough combustion.

What is a High-Level Class I Vehicle?

Vehicle type High-Level Class I refers to an operational vehicle that is a large high-level class I passenger bus. Operational vehicles with a body length greater than 9 meters and less than or equal to 12 meters are classified as large passenger buses. Large passenger buses are further subdivided (from high to low) into High-Level Class III, High-Level Class II, High-Level Class I, Intermediate, and Standard based on different configurations. Compared to other high-level passenger buses, High-Level Class I large and medium-sized buses have identical service facility requirements except for the installation of a restroom. For example, the installation positions of the engine and luggage compartment, the form and structure of the doors, the width of the aisle, the size and performance of the seats, and the requirements for interior trim and air conditioning and control are almost the same. The front and rear suspensions of High-Level Class I large passenger buses must at least consist of a combination of independent front suspension and rear fewer-leaf springs (<4 leaves), or a combination of all air suspension or air suspension with leaf springs. The power-to-weight ratio must be >13.5 kW/t to ensure the dynamic performance, safety, and comfort of High-Level Class I highway operational passenger buses.
