What to do if there are watermarks after applying Crystal 70?

Crystal 70 may have watermarks after application, you can try wiping it with alcohol. Details about Crystal 70 are as follows: The M Crystal 70 series car film is a high-end model: It has a light transmittance of over 70% (actually 71%), with excellent clarity. It uses 3M's exclusive patented multi-layer ceramic optical film substrate, with a thin thickness composed of over 200 layers of optical micro-coatings. Each layer selectively refracts and reflects the sunlight, achieving a maximum heat insulation rate of nearly 60%. Heat insulation rate: The reflection of Crystal 70 is achieved through refraction and reflection, so it is related to the angle of sunlight incidence and is not a fixed value. Actual tests show that when the car window is exposed to direct sunlight and oblique sunlight, the heat insulation rates differ. The heat insulation rate is highest under oblique sunlight, reaching up to 59% for the front windshield, while under direct sunlight, it is only 50%. Of course, this performance is already very high, as mid-range products generally have a heat insulation rate of around 35%. Increasing the heat insulation rate by even one percentage point is very challenging. The higher the rate, the more demanding the requirements become.

How many seconds should the handbrake be engaged during a hill start?

Three seconds. Below is the extended content: After climbing the slope, carefully observe the benchmark and the dotted line marking the parking area on the slope. It is essential to stay focused, avoid excessive speed, and slowly approach the slope's top marker. Pay attention to the coordination of your feet during a hill start: The driver must concentrate and coordinate hand and foot movements. After releasing the brake with the right foot, gently press the accelerator, depress the clutch with the left foot, and then shift into first gear with the right hand. Release the handbrake while gently pressing the accelerator. Additional notes: When the car starts moving forward, keep the clutch pedal steady to ensure a smooth start, then slowly release the clutch pedal until fully engaged; if the car does not move or roll back, slowly release the clutch pedal. Once the car moves, hold the clutch pedal steady, and after the car starts smoothly, slowly release the clutch pedal until fully engaged; in case of a failed start, promptly engage the handbrake and proceed with a standard hill start; try to press the front part of the brake pedal with the right foot, applying more force to the brake pedal than the accelerator to prevent insufficient braking force causing the car to roll back; stalling or rolling back after starting. The clutch control requirement for the hill start in Subject 2 is also very high. First, the clutch must reach the semi-engaged state before releasing the handbrake. Poor clutch control in this task will likely result in failure.

Will the rearview mirror break if folded forward?

Folding the rearview mirror in reverse will not cause damage. Below is relevant information: The rearview mirror has a reverse folding function and can be folded backward. The rearview mirror is a tool that allows the driver to directly obtain external information about the rear, side, and lower parts of the car while seated in the driver's seat. For the convenience of the driver, to prevent traffic safety accidents, and to ensure personal safety, countries have stipulated that cars must be equipped with rearview mirrors, and all rearview mirrors must be adjustable. Rearview mirrors can be divided into two types of adjustment: external and internal. External adjustment: This method involves manually adjusting the position of the mirror frame or mirror surface while the car is parked to achieve the desired viewing angle. This method is time-consuming and labor-intensive, making it difficult to complete conveniently in one go. The driver needs to reach out of the window to adjust it, which is inconvenient while driving or during rainy conditions. Generally, large vehicles, trucks, and low-end buses use external adjustment to reduce costs. Internal adjustment: This method allows the driver to adjust the rearview mirror while driving, providing more convenient conditions for observing the rear view. Most mid-range and high-end cars use internal adjustment. This method is further divided into two types: manual adjustment (via wire cable transmission or handle adjustment) and electric adjustment.

How many points are deducted and what is the fine for crossing the line when turning left?

One point is deducted for crossing the line when turning left. The penalty for crossing the line when turning left is divided into the following three situations: Crossing the white stop line in the left-turn lane: If the vehicle exceeds the zebra crossing area and completes the left turn by crossing the double yellow line near the center of the intersection, it will be fined and one point will be deducted if caught. The front wheel crosses the double solid yellow line: If the vehicle fails to correctly enter the designated lane and the front wheel crosses the double solid yellow line, it will be fined and one point will be deducted. Types of line-crossing violations caught on camera: One is crossing the line while driving. The other is crossing the line while parked. While driving, if the tires on either side of the vehicle cross the solid line, even if only the front wheel crosses or goes beyond the line, it will be penalized as a line-crossing violation if caught on camera. Parking over the line usually refers to the vehicle stopping with its wheels on or crossing the dividing line, and it will be penalized whether caught by manual police photography or electronic photography.
