What does ECO mean in the Highlander?

ECO in the Highlander refers to the vehicle's economic driving mode. ECO is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the ECO indicator light on the dashboard illuminates, it indicates that the vehicle's economic mode has been activated. ECO mode is categorized into active and non-active types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to activate 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. The non-active ECO mode does not have a dedicated button. When the ECO indicator light on the dashboard illuminates, it merely serves as a reminder function. The ECO system 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 employ the active ECO driving mode, meaning they have their own switch button. In daily driving, we can generally activate the ECO mode. 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 only fail to demonstrate the fuel-saving characteristics of ECO but also impact the vehicle's power performance. Additionally, the 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, the ECO mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the ECO mode will not function in such scenarios.

What does it mean when the electronic power steering warning light comes on?

When the yellow "EPS" warning light or "steering wheel" shaped warning light illuminates on the dashboard, the following symptoms may occur: heavy steering, abnormal steering noise, steering wheel vibration, and poor steering wheel return capability. Possible causes of electronic power steering system failure include: 1. Excessive air in the power steering system. 2. Foreign objects in the hydraulic lines causing steering pump flow blockage. 3. Loose steering connections leading to steering fluid leakage. Below is relevant information about this component: On the steering shaft there is a hub with grooves that rotates when turning the steering wheel. There are four equally spaced grooves around the hub. When the turn signal is activated, a plastic lever on the turn signal switch gets pushed into the path of these grooves. As the hub continues rotating clockwise, these grooves strike the plastic lever, causing it to oscillate and allowing each groove to pass. When the steering wheel returns left, the hub rotates counterclockwise, pushing the plastic lever in the opposite direction. This forces the spring-loaded roller out of the switch housing's groove, causing the turn signal lever to snap back to its central position.

How to Properly Cross Speed Bumps in a Vehicle?

Correctly crossing speed bumps involves slowing down in advance and then passing over them straight on, distributing the impact evenly across both tires to balance the suspension load on both sides. This method minimizes damage to the vehicle. Relevant details are as follows: 1. From the perspective of the vehicle body and suspension structure, crossing a speed bump is essentially a compression movement between the wheels (including the suspension) and the ground against the vehicle body. Passing vertically over the bump causes both wheels to contract simultaneously, with the force from the ground evenly shared by the springs and shock absorbers of both wheels, regardless of whether the suspension is independent or non-independent. In this scenario, the vehicle body primarily experiences vertical forces that are symmetrically balanced on both sides, resulting in a more even distribution of stress. 2. Crossing speed bumps at an angle actually causes greater wear and tear on the springs, shock absorbers, and the entire vehicle body (frame). This can inversely explain why crossing at an angle feels more comfortable than going straight over—because the entire system absorbs more energy, leaving less energy (vibration) to be transmitted to the passengers.

Can I upgrade my license from B2 to A2 one year after downgrading from A2 to B2?

A license requires having a B license for at least 5 years. For specific details, you can inquire further at the driving school or the vehicle management office. After downgrading from A2 to B1 or B2, you can apply to upgrade back to A2 one year after completing the downgrade procedure. The conditions are: you must not have accumulated 12 penalty points in the current scoring cycle or the most recent scoring cycle before applying, and you must not have been involved in a traffic accident resulting in death where you bore equal or greater responsibility. The Ministry of Public Security Order No. 139, 'Decision of the Ministry of Public Security on Amendments,' has been approved by the Ministry of Public Security executive meeting and was issued, having taken effect as early as April 1, 2016. After a motor vehicle driver completes the downgrade or license replacement procedure, if they apply to reinstate the canceled permitted driving vehicle type, they must not have accumulated 12 penalty points in the current scoring cycle or the most recent scoring cycle before applying, and they must not have been involved in a traffic accident resulting in death where they bore equal or greater responsibility.

How to Adjust the Vertical and Horizontal Alignment of Car Headlights?

Car headlight vertical and horizontal adjustment methods are as follows: 1. Vehicle light adjustment typically involves the left-right and up-down alignment of low beams. This can be done using the adjustment knobs located at the rear of the headlight assembly, allowing owners to adjust the lights themselves with appropriate tools. 2. Open the engine hood, locate the adjustment knobs at the rear of the headlight assembly, and use the corresponding tools for adjustment. Before adjusting, determine whether the knob controls left-right or up-down movement. 3. Park the vehicle facing a wall at a distance of approximately 10 meters. Observe the height of both headlights and, if necessary, use tape or other markers for measurement, comparison, and adjustment. 4. After adjusting the horizontal alignment of the headlights against the wall, find a reference point on the vehicle for comparison. Adjust the headlight height at a distance of about 10 meters, and adjust the horizontal position when closer. 5. After completing the adjustments, observe the lights from both inside and outside the vehicle. You can also simulate the height from the opposite direction for verification. Repeat the adjustments until satisfactory. High beams usually do not require adjustment.
