What do D+ and D- mean in cars?

Automatic transmission D+ or D- means the ability to freely shift down gears, allowing high-performance sports cars to break free from the constraints of traditional automatic transmissions and enabling drivers to enjoy the fun of manual shifting. Below is an introduction to automatic transmissions: Automatic Principle: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume over 10% more fuel than manual transmissions. Whether manual or automatic, the more gears a transmission has, the more fuel-efficient it is. Driving Tips: For manual transmission cars, it is recommended to shift up at higher RPMs. Engines are designed to operate at higher RPMs, with various components' dynamic balance and rotational inertia parameters also designed based on high RPMs. If the engine operates for extended periods outside its normal working range, internal component load and wear naturally increase, leading to frequent vibrations and knocking, which can affect lifespan. Choosing 3000 RPM as the shift-up point ensures that after shifting, the engine operates at around 2300 RPM, keeping it within a healthy RPM range.

What grade of gasoline is suitable for Jetta VS5?

Jetta VS5 uses 95 octane gasoline. More information about 95 octane gasoline and car refueling is as follows: 1. 95 octane gasoline consists of 95% isooctane and 5% n-heptane. When the engine compression ratio is high, high-octane gasoline should be used. If low-octane gasoline is used with a high compression ratio, it may cause abnormal phenomena. Nowadays, high-compression engines can also use lower-grade gasoline, but the selection of gasoline grade should not be blindly based on the compression ratio. Instead, follow the manufacturer's requirements for refueling; 2. The fuel tank capacity of the Jetta VS5 is 51 liters. When refueling, it is recommended that owners do not overfill the tank. Additionally, try to choose large and reputable gas stations for refueling and avoid adding substandard fuel to save money.

Will spilled engine oil burn if it's on the outside of the engine?

Spilled engine oil on the outside of the engine will not burn. Simply wipe it clean with a cloth promptly to prevent smoke when the engine temperature rises. Be sure to check the engine oil level. Below is relevant information about engine oil: Introduction: Engine oil, also known as engine lubricant, with a density of approximately 0.91×10³ (kg/m³), serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricants, determining their fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, providing additional performance characteristics. Classification: Engine oils on the market can be broadly categorized into mineral oils and synthetic oils based on their base oil (vegetable oils are not considered due to their scarcity). Synthetic oils are further divided into full synthetic and semi-synthetic.

What is the optimal mileage for the first maintenance of a new car?

3000-5000 kilometers. The first maintenance for a new car includes the following: 1. Check whether the coolant level meets the specified requirements. 2. Inspect the brake and clutch fluid levels. 3. Verify the power steering fluid level and check for any oil leaks at the system's pipe connections. 4. Examine the battery fluid level and the windshield washer fluid level. 5. Check the tension and aging condition of the belts for the generator, air conditioning, water pump, and power steering pump. 6. Ensure all front and rear lights are functioning, including headlights, width markers, turn signals, brake lights, reverse lights, and fog lights. 7. Inspect tire pressure and wear, tighten the tire bolts to the specified torque, adjust tire pressure to the manufacturer's recommended level, and rotate the tires if necessary based on wear. 8. Check whether the vehicle's exhaust emissions meet the standards.

Are There Age Restrictions for Motorcycle Licenses?

There are age restrictions for motorcycle licenses. The age limit for light motorcycles is between 18 and 70 years old, while the age limit for regular three-wheeled motorcycles and regular two-wheeled motorcycles is between 18 and 60 years old. "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": Article 59: Individuals aged 60 or above are not permitted to drive large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, large trucks, trolleybuses, or tramcars. Those holding driver's licenses for large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, or large trucks must apply at the vehicle management office where the license was issued or another office to exchange their license for one that permits driving small cars or small automatic transmission vehicles. Individuals aged 70 or above are not permitted to drive low-speed trucks, three-wheeled vehicles, regular three-wheeled motorcycles, regular two-wheeled motorcycles, or wheeled self-propelled machinery. Those holding driver's licenses for regular three-wheeled motorcycles or regular two-wheeled motorcycles must apply at the vehicle management office where the license was issued or another office to exchange their license for one that permits driving light motorcycles.

How many kilometers can the Avalon run in EV mode?

The EV mode of the Avalon refers to the pure electric mode. The range of the Avalon in pure electric mode is relatively low, and it can run about 20 kilometers in EV mode. Introduction to the Avalon: The Avalon is a mid-size 4-door 5-seater sedan with a body length of 4975mm, width of 1850mm, height of 1450mm, and a wheelbase of 2870mm. The fuel tank capacity is 60L. The Avalon is equipped with a 2.5L naturally aspirated engine and an 8-speed automatic transmission, with a maximum power of 154 kW at 6600 rpm and a maximum torque of 250 Nm. It features front-wheel drive, with MacPherson strut front suspension and E-type multi-link rear suspension. Introduction to EV mode: EV mode is the pure electric drive mode, where the car's power is entirely driven by the electric motor. This mode can be found in plug-in hybrid models, which can be driven by either fuel or EV mode. To better distinguish, EV is used to represent the pure electric mode.
