Where is the SD card slot for the CT6 dash cam located?

The SD card slot for the Cadillac CT6 dash cam is located on the right side of the rear section inside the trunk. This slot is specifically for the additional streaming media device. Below is a brief introduction to the Cadillac CT6: 1. CT6's rearview mirror: The Cadillac CT6 was the first to utilize a technology called streaming media video rearview mirror. This rearview mirror features a TFT-LCD display with a resolution of 1280*240, and an external rearview camera captures and relays the rear view to the interior mirror. The streaming media video rearview mirror can expand the rear visibility range by three times. 2. CT6's exterior design: The Cadillac CT6's design draws inspiration from the Elmiraj concept car, incorporating a flatter, wider, and more layered shield-shaped grille. The headlights have an aggressive design, combined with Cadillac's classic diamond-cut design elements, giving the front fascia a very dynamic appearance. On the side profile, the CT6 features smooth body lines with two character lines that enhance its sporty visual appeal. 3.

Can hydraulic oil be added to the steering gear?

Hydraulic oil cannot be added to the steering gear. Because the viscosity of hydraulic oil is different from that of power steering fluid, mixing different types of hydraulic oil will affect the normal operation of the steering gear. Different machines have specific requirements for the viscosity of hydraulic oil. Different types of oil operate in different environments, with varying additive formulations and base oil requirements, so they should not be mixed. More details are as follows: 1. The liquid used in the hydraulic braking system is called brake fluid, which does not undergo chemical reactions, is unaffected by high temperatures, and does not corrode, soften, or expand metals and rubber. Power steering fluid, on the other hand, is a transmission fluid, and a key indicator is its low-temperature fluidity. Even at temperatures as low as several tens of degrees below zero, it does not thicken, ensuring smooth control of the steering gear. 2. Power steering fluid is a special liquid used in the car's power steering pump. Through hydraulic action, it makes the steering wheel very easy to turn, similar to automatic transmission fluid, brake fluid, and shock absorber fluid. 3. If hydraulic oil is not replenished in time when it is low, minor issues may include loss of power steering assistance and loud power steering noise, while severe cases may result in the power steering pump burning out, affecting normal use.

Which Piece of Glass in a Sedan is the Most Expensive?

The triangular small glass in a sedan is the most expensive. Below is relevant information about the production and design of this triangular small glass: 1. Design principle of the triangular small glass: This small triangular piece of glass is uniquely designed. The purpose of this design in the car body is to achieve a visually harmonious and aesthetically pleasing effect for the overall appearance of the vehicle. The side rear of the car incorporates a triangular window design, with chrome trim decorating the upper part of the overall window, and the contour features a new style. The triangular window next to the rearview mirror also serves to reinforce the connection between the window and the window lift guide rails, ensuring smoother and more stable operation during the window's up and down movement. This design prevents any jamming or stuttering when the window is being raised or lowered. 2. Reasons for the high cost of the triangular glass: Firstly, this small piece of glass is relatively difficult to manufacture, with significant challenges in sealing design during the production process. Even the slightest data during production requires precise calculation. Most importantly, this glass is more prone to aging compared to other car windows. Therefore, during the manufacturing process, in addition to considering sealing, attention must also be paid to issues such as noise and environmental factors causing glass aging. This makes the use of this glass highly particular, which is why its price is higher than that of larger glass pieces.

How many points are deducted for making an immediate U-turn after driving in the wrong direction on a highway?

Making an immediate U-turn after driving in the wrong direction on a highway will result in a deduction of 12 points and a fine. Prohibited U-turn situations are as follows: U-turns are prohibited where there are "No U-turn" or "No Left Turn" signs: If there is a sign prohibiting U-turns, then U-turns are not allowed at that intersection. A U-turn is an extension of a left turn, so if there is a sign prohibiting left turns at an intersection, U-turns are also prohibited there. U-turns are prohibited at crosswalks: U-turns are not allowed at crosswalks. If U-turns are permitted at an intersection, you must cross the crosswalk before making the U-turn; you cannot make a U-turn on the crosswalk. U-turns are prohibited when there is no left-turn lane: Even if you are in the leftmost lane, U-turns are not allowed if there is no sign permitting left turns. U-turns are prohibited from the second left-turn lane: When a vehicle is in the second left-turn lane, it cannot make a U-turn. In the absence of any signs, U-turns are only allowed from the innermost left-turn lane. U-turns are prohibited at solid yellow lines: U-turns are not allowed at solid yellow lines. Even if there is a sign permitting U-turns, you must wait for the green light and cross the stop line to make the U-turn. U-turns are prohibited on highways: Crossing the central divider to make a U-turn on a highway is illegal and will result in a fine and a deduction of 12 points. If you miss an exit on the highway, continue driving to the next exit to leave the highway; never attempt an illegal U-turn.

How Long Can Tesla Dash Cam Footage Be Saved?

Tesla dash cam footage can typically be saved on the memory card for one to two years under normal conditions. The duration before the footage is overwritten depends on the maximum supported capacity of the dash cam and the size of the memory card. Below is additional information about dash cam memory cards: 1. Common memory card sizes for dash cams on the market: Most dash cams support 32G, while some support 64G. The Mingju M2 panoramic dash cam, an industry-first national patent-subsidized product, features 4 lenses, dual 1440P resolution, dual WiFi, and dual memory, supporting up to 256G—currently the largest supported capacity for dash cams. Due to technological and cost limitations, dash cams usually have capacity restrictions. For example, a dash cam that supports up to 32G can only recognize the first 32G of a 64G card, rendering the remaining capacity unusable. Therefore, using a 64G memory card in a 32G-limited dash cam is wasteful, as it can only utilize 32G of the 64G or may not recognize the excess capacity at all. 2. How to evaluate the quality of a dash cam: Assess based on the memory usage over time. For a 32G memory card at the mainstream 1080p resolution (which is not ideal), approximately 120MB of storage is needed per minute of recording, equating to about 7G per hour. For 720p resolution (an outdated standard), around 80MB per minute or 4.7G per hour is required. Many 720p or 1080p dash cams are misleadingly marketed as "high-definition," falsely claiming to match 1296p or 1440p (currently the highest resolution). With a 32G memory card, a 1080p dash cam can record continuously for about 4.5 hours. For dual-lens setups (sharing one memory card), with the front camera at 1080p and the rear at 720p (the highest resolution supported for rear cameras in China), recording time drops to approximately 3 hours. Notably, the Mingju M2 is the first domestic dash cam to support 1080p for both side and rear views.
