What does car eco represent?

eco represents the economic mode among driving modes. Nowadays, cars have many driving modes, including "off-road mode", "sport mode", and "snow mode". The name eco is derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). It is further divided into active and non-active eco modes. The difference lies in that the active mode has a dedicated button, while the non-active mode does not have a dedicated button and only serves as a reminder or guide. Additional information: The eco mode usually becomes ineffective under the following circumstances: 1. When the vehicle speed exceeds 120 kilometers per hour, considering the speed factor, the eco mode automatically becomes ineffective. 2. When idling in park or in N/P gear, or in manual mode, the eco mode may also become ineffective. 3. When high torque output is required, such as when climbing a slope, the engine computer will prioritize ensuring sufficient power to drive the vehicle, and the eco mode will not work either.

Can You Get a Driver's License with One Blind Eye?

You can get a driver's license even if one eye is blind. Before the policy was revised, individuals with monocular vision were not allowed to obtain a driver's license, but after the policy change, they became eligible. The revised "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" in 2016 clearly states: For those with monocular vision impairment, if the better eye (the eye with better vision) achieves a naked or corrected visual acuity of 5.0 or above on the logarithmic visual acuity chart, and the horizontal visual field reaches 150 degrees, they can apply for a driver's license. (Note: People with red-green color blindness are still not allowed to obtain a driver's license.) Additional information: 1. For individuals with monocular vision, the driver's license medical examination is not much different from that of normal people, except for some special requirements regarding vision, so the process is not particularly troublesome. 2. There is an additional special test item for individuals with monocular vision during the vision examination: the horizontal visual field test. This ensures that drivers with monocular vision can clearly see straight ahead and effectively avoid driving risks from the left and right sides.

Can a Regular Battery Be Used to Replace the One in a Vehicle with Auto Start-Stop?

For vehicles equipped with an auto start-stop function, it is not recommended to replace the battery with a regular one. The specific reasons are as follows: 1. Using a regular battery may lead to insufficient working current for the starter: When a vehicle has an auto start-stop function, the starter requires a larger working current during operation. A regular battery cannot support such a high current, so only an auto start-stop battery capable of delivering a higher current output should be used. Due to the higher cost of such batteries, many car owners opt for regular batteries to save money during replacement. However, this practice can damage the starter. 2. Impact on power management: If a regular battery is installed in a vehicle with an auto start-stop function, it may cause abnormal power management. For example, some car owners who switch to regular batteries and disable the auto start-stop function still experience issues such as the battery not charging fully, mismatched power management systems, or the car failing to start. 3. Health risks for passengers: Auto start-stop batteries have relatively weaker heat resistance, so they are usually placed in the trunk or inside the cabin to avoid exposure to high temperatures from the engine. If a regular battery is installed, it may produce acid mist and other harmful gases during charging and discharging, posing health risks to passengers.

Must the owner go in person for the first maintenance?

No. But the owner's driver's license and maintenance manual need to be brought. Additional information: 1. The first maintenance, also called the initial maintenance, refers to the first maintenance after the running-in period of a new car. The so-called running-in period refers to the process in which various parts of a new car (especially the engine parts) continuously rub and mesh with each other during operation. Only after running-in can the parts cooperate seamlessly and the vehicle can perform to its full potential. 2. During the running-in process, the engine of a new car usually produces more metal shavings, oxidized engine oil, carbon deposits and other impurities. Although the oil filter can filter out most of the impurities, some may inevitably be missed. Once there are too many impurities in the engine oil and they are not cleaned in time, it will lead to high fuel consumption and excessive engine wear. Therefore, after the running-in period of a new car, the first maintenance is required.

Is Engine Cleaner Useful?

Engine cleaner is useful, but its effectiveness is relatively limited. Engine cleaner can remove residual sludge from the engine oil passages and, to some extent, clean carbon deposits from the piston rings and ring grooves, providing practical maintenance benefits for the engine. However, due to its short retention time in the engine lubrication system and the inherent limitations of this no-disassembly cleaning method, the effectiveness of engine cleaner is relatively limited. Additional information: Reasons why the engine lubrication system requires regular cleaning: During engine operation, wear caused by the relative motion and friction of various moving surfaces, as well as the combustible gas mixture entering the crankcase from the cylinders, can affect the performance and quality of the engine oil. When the performance and quality of the engine oil decline, its ability to clean the engine oil passages also decreases, eventually leading to sludge buildup in the engine lubrication system and, in severe cases, even clogging the oil passages. Therefore, the engine lubrication system needs to be cleaned regularly.

Will the Car Lock Automatically If the Key Is Inside?

For models equipped with a "keyless entry" feature, the car can detect the presence of the key inside and the onboard computer will prevent automatic locking. For models without the "keyless entry" feature, if the vehicle is turned off and the doors are closed without the key, both the doors and trunk will automatically lock after a few minutes. Additional Information: Solutions for accidental locking are as follows: 1. The most direct and effective solution is to use the spare key. Consumers receive a spare key when purchasing a car, typically a mechanical key. Locate the mechanical keyhole on the driver's side and use the spare key to unlock the door. 2. For vehicles equipped with telematics, calling customer service can enable remote unlocking of the doors. 3. Contacting a professional locksmith is another option. It's important to note that legitimate locksmith companies will require the owner to provide valid identification and proof of vehicle ownership, among other documents.
