What are optional features in cars?

Optional features refer to configurations that are not part of the standard equipment for a particular car model. Standard features are mandatory, while optional features can be selected according to the buyer's preferences or needs when placing an order. Below is an introduction to related content: 1. More expensive configurations are not necessarily better: The more accessories a car has, the higher its maintenance risk rate. Appropriate decorative configurations can achieve both safety and comfort. Thus, "safety" and "comfort" become the two major principles consumers should follow when selecting configurations. 2. Optional features: Optional features often belong to enrichment configurations, which do not affect the vehicle's safety performance or power performance but can enhance comfort, practicality, and high-tech experiences, such as parking sensors and digital head-up displays. 3. Identification: Optional features are usually marked in the car's parameter specifications, such as "hollow circles" and "thin solid lines," though the symbols used may vary among different car manufacturers.

What is the difference between V-rated and H-rated tires?

Here are the differences between V-rated and H-rated tires and related information about tire speed ratings: 1. Main differences between V-rated and H-rated tires: (1) Different speed ratings: H indicates a maximum safe speed of 210 kilometers per hour; V indicates a maximum safe speed of 240 kilometers per hour. (2) Different performance: The higher speed-rated V tire represents stronger tire performance. It's important to know that when tires roll at high speeds, they generate heat due to squeezing and deformation, so the higher-rated V tire naturally has better resistance. 2. Speed ratings: The letters corresponding to tire speed ratings represent the certified speed grades of tires from 4.8 km/h to 300 km/h. J, K, L, M, N, P, Q, R, S, T, U, H, V, W, Y, Z are the letters corresponding to tire speed ratings. Among them, J-Y represent 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 240, 270, 300 kilometers per hour, while Z represents speeds above 240 kilometers per hour.

Why Does Manual Gear Shifting Feel Stiff and Jerky?

Reasons for stiff and jerky manual gear shifting: 1. Rusty transmission shaft: The clutch driven disc cannot move normally and has poor return, preventing the gear from engaging along the normal trajectory; 2. Clutch malfunction: Insufficient clutch separation formation, leading to incomplete clutch separation and inability to engage gears; 3. Poor clutch separation: The transmission plate of the pressure plate assembly is deformed for some reason, resulting in poor separation; 4. Transmission oil is too old or insufficient; 5. Cold gear shifting: Makes the gear feel stiff, especially in cold temperatures where the viscosity of the gear oil in the transmission cannot reach the ideal state, naturally resulting in poor lubrication.

How to Adjust Car Headlights for Focused Beam?

Due to inherent design issues or various factors during modification, LED headlights may experience severe light scattering and lack of focus. Therefore, it is necessary to adjust the beam angle to meet the driver's safety requirements. The adjustment steps are as follows: 1. First, park the car 7.6 meters away from a wall, turn on the headlights, and then adjust the beam position based on the light pattern on the wall. Some vehicle models come with an integrated headlight height adjustment knob inside the car. If this feature is available, set the headlight height adjustment knob to the "0" position before adjusting the headlights. 2. Next, mark reference lines on the wall. Measure the distance from the center of the low beam to the vehicle's central axis, the distance from the center of the high beam to the vehicle's central axis, and the distance from the center of the low beam to the ground beforehand. 3. Finally, adjust the corresponding adjustment knobs located at the back of the headlights to fine-tune the beam position. The specific parts to adjust and the tools required may vary depending on the vehicle model. Before making adjustments, project the headlights onto the wall and observe whether the beam is misaligned, too high, or too low.

Does the New Santana Lack a Rear Bumper Beam?

The New Santana is only equipped with a front anti-collision steel beam and does not have a rear bumper beam. Below is relevant information about the New Santana: 1. Exterior: The exterior completely abandons the boxy styling of the 1970s seen in the old Santana, replacing it with a more modern and stylish dynamic design, which now fully adopts the latest appearance of the Volkswagen family. The family-style front-end design makes it difficult to distinguish between Volkswagen's compact models, blurring the lines between these vehicles for many people. 2. Configuration: The New Santana is powered by 1.4L and 1.6L engines, codenamed EA211. This series of engines will include two displacements, with the 1.4L engine delivering a maximum power of 66kW and the 1.6L engine offering a maximum power of 81kW, both featuring a lighter all-aluminum structure. The transmission remains the same as the POLO, with a 5-speed manual and a 6-speed Tiptronic automatic transmission. The addition of the 6AT gives this not-so-high-end car better high-speed performance.

Should You Press the Clutch or Brake When Going Down a Steep Slope?

When going downhill, you should press the brake. The specific reasons are as follows: 1. Precautions for downhill driving: When going downhill, you should press the brake and shift to a lower gear, and try to avoid pressing the clutch continuously. For manual transmission vehicles, you should not shift to neutral or press the clutch when going downhill; instead, lightly apply the brake to control the speed. 2. Reasons for using the foot brake: When coasting in neutral, relying solely on the foot brake will cause the front brake discs to overheat, significantly reducing their effectiveness. Moreover, if the speed is too high, coasting in neutral makes it difficult to control the vehicle's speed, so shifting to neutral when going downhill poses a high risk.
