If waiting at a red light for about 10 seconds, stay in D gear and press the brake, then drive directly when the light turns green. If the wait is longer, over half a minute, shift to N gear. Below is relevant information about automatic transmission cars: 1. Introduction: D gear is the drive gear, which always has power output, while N gear is the neutral gear, which does not wear the transmission. If the road has a slope, shift to N gear while pressing the brake to prevent the car from rolling. Many vehicles are equipped with an automatic parking function: when the brake is pressed until the vehicle comes to a complete stop, releasing the foot will not cause the vehicle to move, and pressing the accelerator again will resume driving. This feature can free the driver's feet during stops and is useful for slightly longer waits. 2. Precautions: Do not shift to P gear when waiting at a red light. If the car is in P gear during a red light and gets rear-ended, the transmission could be severely damaged.

How does Tesla Supercharging billing work?

Tesla offers 400 kWh of free charging credit in the first year, which is only applicable to the vehicle itself and cannot be transferred or refunded. After exceeding the 400 kWh limit, fees will be automatically deducted from the credit card linked to the Tesla account. Below are detailed explanations about it: 1. Explanation one: The 400 kWh of free charging credit per year cannot be carried over to the next year if unused. On each annual delivery anniversary, the vehicle's free Supercharger credit will be reset to 400 kWh. 2. Explanation two: If the vehicle continues to occupy a Supercharger parking spot after charging is completed, a certain idle fee will be charged.

Can dents at the edges of a car be repaired without leaving marks?

Dents at the edges of a car can be repaired without leaving marks if they are not severe. Here is some relevant information about car dent repair technology: 1. Definition: Paintless dent repair (also known as vehicle dent repair) refers to a technique that restores the dented and deformed parts of a car body while preserving the original paint. 2. Advantages: Car dent repair can retain the original paint, reduce repair time and costs, is not restricted by location, and does not alter the vehicle's key safety parameters. 3. Applicability: Car dent repair technology is not only suitable for small-area dent repairs but can also be used to repair certain characteristic large-area dent damage.

What does the Mercedes-Benz poff button mean?

Mercedes-Benz poff button is the control switch for the parking radar. Below is relevant information about the parking radar: 1. Introduction: The parking radar system, also known as the parking assistance system, informs the driver of surrounding obstacles through sound and visual display. It eliminates the troubles caused by the driver's need to look around when parking, reversing, or starting the vehicle, helping the driver to clear blind spots and improve driving safety. 2. Working Principle: The parking radar uses ultrasonic detection, similar to the principle that bats can fly at high speed at night without colliding with any obstacles.

What are the methods and sequence for car paint polishing?

Here is an introduction to the methods and sequence of car paint polishing: 1. Wash the car: Before polishing, it is essential to thoroughly clean the car body to remove dust particles, preventing secondary damage to the paint. 2. Sanding: After washing the car, perform a rough sanding on the body. Depending on the size of surface imperfections or scratches, use water sandpaper of different sizes for sanding. 3. Polishing: After sanding, select an appropriate polishing machine along with polishing wax to perform detailed polishing on the sanded body. 4. Mirror restoration: After polishing, use a mirror treatment agent to restore the mirror-like effect of the car body, followed by waxing and shining.

What is the issue when the brake pedal goes all the way to the floor with one step?

There are mainly three reasons that can cause the brakes to feel soft: 1. Air in the brake fluid reservoir: If the brake fluid has just been replaced, it is likely that the mechanic did not fully bleed the air from the brake lines. Air in the lines will make the vehicle's brakes feel weak and ineffective. 2. Severely worn brake pads: When brake pads wear down, their overall thickness becomes thinner, requiring the driver to press the brake pedal deeper to achieve the original braking effect. 3. Insufficient brake fluid: Check the brake fluid level in the reservoir to ensure it is between the MAX and MIN marks. If the brake fluid is below the MIN mark, it indicates insufficient brake fluid.

How to Use the Brake Assist Function?

Brake assist function is used as follows: 1. Prevent wheel lock-up: It can be used to prevent wheel lock-up when braking. During vehicle braking, axial load transfer occurs, automatically adjusting the front and rear axle braking power distribution ratio to improve braking efficiency. It detects the driver's braking action and increases braking force during emergency braking to shorten stopping distance. 2. Avoid loss of control: When the vehicle experiences wheel slip, tilt, or tire loss of traction moment, it purposefully applies braking control to individual wheels while reducing engine speed, ultimately guiding the vehicle back to normal driving trajectory to prevent dangers caused by loss of control. 3. Stabilize the vehicle: By controlling the magnitude of driving force, it reduces the slip rate of drive wheel tires, prevents jolting, and helps the vehicle maintain stability.
