ECO indicates that the vehicle's economical driving mode is activated. ECO is an English abbreviation derived from 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 signifies that the vehicle's economical mode has been engaged. Eco mode comes in active and non-active forms. The difference lies in the fact that the active mode has a 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. Non-active Eco mode lacks a dedicated button; when the dashboard ECO light illuminates, it serves merely as a reminder. The system automatically evaluates your driving behavior, and 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 a dedicated switch button. During everyday driving, we can activate Eco mode, except when driving at speeds exceeding 120 km/h, idling, in N/P gear, or in manual mode—especially when climbing hills. In these scenarios, activating Eco mode would not only fail to demonstrate its fuel-saving characteristics but also impact the vehicle's power performance. Additionally, Eco mode typically deactivates under the following conditions: When the vehicle speed exceeds 120 km/h, the system prioritizes speed, causing Eco mode to automatically deactivate. When idling or in N/P gear or manual mode, Eco mode may also deactivate. 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 Eco mode will not operate.

Is it allowed to smoke while driving?

Smoking while driving is not allowed and is considered illegal. If caught by traffic police, you will be fined. Smoking while driving falls under behaviors that hinder safe driving: Road traffic safety laws and regulations explicitly prohibit certain actions by motor vehicle drivers while operating a vehicle, which are classified as behaviors that obstruct safe driving. These include making or answering handheld phone calls, watching TV, or any other activities that distract from safe driving, throwing objects onto the road, honking in areas or sections where horn use is prohibited, among others. Smoking while driving poses significant safety hazards: When smoking while driving, the driver's attention is difficult to fully concentrate on driving, which can easily lead to safety incidents. The moment a driver thinks about smoking, their attention is already diverted. Holding a cigarette means only one hand is on the steering wheel, making it difficult to react promptly if the vehicle ahead suddenly changes lanes, thereby increasing the risk of traffic accidents.

Why is there strong suction when opening the oil dipstick on a Cruze?

The reasons for strong suction when opening the oil dipstick on a Cruze are: poor sealing of the oil cap, damage to the exhaust valve, or the oil cap being tightened too tightly during car maintenance. Below are detailed explanations: Poor sealing of the oil cap: After the engine starts, it operates in a negative pressure state where outside air cannot enter. When opening the oil cap, a suction phenomenon occurs. If the sealing performance of the oil cap is not particularly good, the negative pressure phenomenon will be more pronounced. Damage to the exhaust valve: When the exhaust valve is damaged, it cannot control the exhaust gas recirculation volume. This not only affects the stability of engine intake but also causes engine idle vibration. In this case, it is necessary to replace the exhaust valve promptly to effectively resolve the issue of strong suction from the oil cap. Oil cap tightened too tightly: Because maintenance personnel tightened the oil cap too tightly, making it impossible to open by hand, tools can be used to open it. You can drive the car to an auto repair shop or a 4S store and leave it to professionals to handle.

How many points does a driver's license that hasn't been valid for a full year have?

A driver's license that hasn't been valid for a full year has 12 points, but the consequences of deducting points during the probation period vary depending on the type of license. Below are the detailed explanations: Points deduction during the probation period for a C1 driver's license: If a C1 driver's license has 1 to 11 points deducted during the probation period, the driver should normally pay the fines for the traffic violations and accept the point deductions. The points will be restored at the end of the scoring cycle. However, if 12 points are deducted, the probationary license will be automatically revoked. The driver will need to reapply for the C1 driver's license exam, and a new license will be issued after passing all four test sections (from Section 1 to Section 4). Points deduction during the probation period for A or B class driver's licenses: For A or B class driver's licenses, if 1 to 5 points are deducted, the driver should normally handle the traffic violation records, and the points will be restored at the cycle's end. If 6 to 11 points are deducted, according to relevant regulations, the probation period will be extended by one year, and the driver must still handle the penalties for the violations. However, if 12 or more points are deducted during the probation period, the license for that probationary class will be revoked.
