Does the highway LED screen display speeding?

Highway-installed speed display screens generally do not have speed enforcement capture functionality. They are merely LED screens that provide real-time speed feedback as a warning mechanism. When the vehicle is not speeding, the displayed speed value appears in green; when speeding is detected, it turns red. Below is supplementary information about speeding: 1. Penalty standards for motor vehicle speeding: (1) Exceeding the speed limit by less than 10%: no fine, but 3 demerit points; (2) Exceeding by 10% to under 20%: fine imposed plus 3 demerit points; (3) Exceeding by 20% to under 50%: fine imposed plus 3 demerit points; (4) Exceeding by 50% to under 70%: fine imposed plus 6 demerit points, with possible license suspension; (5) Exceeding by 70% or more: fine imposed plus 6 demerit points, with possible license suspension. 2. Principle of LED speed displays: When vehicles enter the radar detection zone, the radar continuously emits electromagnetic waves that reflect off moving vehicles. The system calculates the target vehicle's speed based on the frequency difference between emitted and reflected waves. These radars feature serial port output - after chip processing, the detected speed is transmitted to the LED display and ultimately communicated to the driver.

What is the reason for the occasional idle shaking of the Cadillac XTS?

The reasons for the occasional idle shaking of the Cadillac XTS are: 1. Severe engine carbon deposits: If there is excessive carbon buildup in the engine, the vehicle may exhibit symptoms such as poor engine performance, increased fuel consumption, or even difficulty starting. Over time, this can cause significant damage to the vehicle. 2. Unstable oil pressure: There are many factors that can cause unstable engine oil pressure, such as insufficient oil, dirty oil, thinning oil, oil pipe leakage, oil pump damage, or excessive wear of its components. 3. Issues with the ignition system: When certain components or circuits of the car's ignition system experience open circuits or short circuits, resulting in insufficient primary current, low secondary voltage, or failed ignition timing adjustment, it can lead to unstable engine operation, deteriorating acceleration performance, reduced power and fuel economy, and also cause idle shaking. The Cadillac XTS is a newly positioned large luxury sedan by Cadillac, featuring 20-inch 11-spoke wheels and Bridgestone tires. Components such as LED headlights and a spoiler mounted on the trunk lid showcase its all-new design style.

What causes the car to touch the right line in an S-curve?

Turning the steering wheel back too early causes the car to touch the right line. Driving through an S-curve is one of the test items in Subject 2 of the driving test, primarily assessing the candidate's ability to correctly navigate specific curved road sections. The most common mistake people make is turning or returning the steering wheel too early. Here is an introduction to the S-curve: There are two types of entrances: One is the left entrance, and the other is the right entrance. When entering from the left, the vehicle must stay as close as possible to the right sideline before turning the steering wheel to the left. Conversely, when entering from the right, the vehicle must stay as close as possible to the left sideline before turning the steering wheel to the right. Due to the existence of the inner wheel difference, this factor must be considered to avoid touching the line. During the driving process: The front of the car must always follow the sideline. When turning left, the front of the car should follow the right sideline, and when turning right, the front of the car should follow the left sideline.

What is Prado ECO?

ECO in Prado vehicles refers to the economic driving mode. ECO is an English abbreviation formed by the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). When the ECO indicator light on the dashboard illuminates, it indicates that the vehicle's economic mode has been activated. ECO mode is divided into active and non-active types. The difference lies in that the active type has its own dedicated button, allowing the driver to choose whether to enable it. When the driver presses the ECO mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active ECO mode does not have a dedicated button. When the dashboard ECO indicator light turns on, it serves merely as a reminder function. ECO automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most vehicles adopt the active ECO driving mode, meaning they have their own switch button. Therefore, ECO mode can be enabled during daily driving. However, it is unnecessary to enable ECO mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not reflect the economic fuel-saving characteristics of ECO and could also affect power performance. Additionally, ECO mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the system prioritizes speed, causing the ECO mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, ECO may also become ineffective. When high torque output is required, such as when climbing hills, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and ECO mode will not function in such scenarios.
