Now all ETC devices are solar-powered. The ETC electronic tag equipment operates on a solar + battery mode, usually in a dormant state and only wakes up when triggered, which is very energy-efficient. It also maintains a solar charging state during normal times. More details are as follows: 1. Generally, ETC devices use lithium batteries internally and are charged by solar panels externally. Under normal use, they last about 3 years. If there are any quality issues within the 2-year warranty period, you can bring the ETC device to an ETC service point for replacement. 2. For users who do not frequently use ETC, it is recommended to charge the ETC electronic tag once every 3 months to prevent the internal battery from natural discharge affecting its usage.

Can I Turn Left When the Left Turn Signal is On in a Straight Lane?

You cannot turn left when the left turn signal is on in a straight lane. Turning left from a straight lane is a traffic violation: Turning left from a straight lane is a traffic violation that results in a 2-point deduction. According to the Road Traffic Safety Law, this behavior constitutes driving a motor vehicle without following the designated lane markings and will result in a 2-point deduction and a fine of 100 yuan. Article 51, Section 2, Chapter 4 of the Road Traffic Safety Law of the People's Republic of China states: At intersections with lane indication signs and directional lanes, vehicles must follow the designated lanes in advance based on the direction of travel. Motor vehicle signal lights indicate: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motor vehicle signal lights or pedestrian crossing signal lights, non-motor vehicles and pedestrians must follow the indications of the motor vehicle signal lights.

What are the four colors of the Tianlong flagship called?

The colors of the Tianlong flagship include China Red, Pearl Molybdenum Red, Blue, Green, and Black. Battery Capacity: The Dongfeng Tianlong pure electric heavy truck does not differ much in appearance from the regular Tianlong flagship model, except that the fuel tanks on both sides and various equipment have been replaced with batteries. The Dongfeng Tianlong flagship pure electric tractor is equipped with a total of 10 battery packs, but the current battery capacity is unknown. Range: The range affects the vehicle's working mode. Based on current battery technology, pure electric heavy trucks still face certain challenges in long-haul transportation. Perhaps short-distance operations like port drayage and other short-haul transportation are more suitable for this vehicle.

What is the correct start-stop sequence for keyless ignition?

When using keyless ignition, you need to press the foot brake and press the start-stop button to ignite the car. Introduction to the keyless ignition system: The keyless ignition system allows you to start the vehicle without inserting or turning a key. As long as the smart key is inside the car, pressing the START button can directly ignite or turn off the engine. The keyless ignition system is a more advanced configuration than the keyless entry system. Vehicles equipped with the keyless ignition system also have the keyless entry system, but vehicles with the keyless entry system may not necessarily have the keyless ignition system. Keyless ignition steps: First, after the driver sits in the driver's seat, without pressing the brake, press the start button once—the ACC light will turn on. Next, the driver presses the brake and presses the one-touch start button to ignite the engine. Then, release the foot brake; you can choose to warm up the car in place. Press the foot brake again, shift into D gear, release the handbrake, and finally, slowly release the foot brake while gently pressing the accelerator to complete the start.

Is Manual Transmission a Dry Dual Clutch?

Manual transmission is not a dry dual clutch. Different cooling methods: The biggest difference between dry dual clutch and wet dual clutch is the cooling method. The dry dual clutch transmission cools down through air cooling, while the wet dual clutch transmission cools down through oil. Basically the same structure: The structure of dry dual clutch transmission and wet dual clutch transmission is basically the same, relatively simple. To put it bluntly, it is a combination of two sets of manual transmissions, with not high technical content and relatively low manufacturing costs. Traditional AT automatic transmission: Although stable and reliable, with a simple structure and low maintenance costs, due to outdated technology, it is gradually being phased out. Especially over time, the jerking sensation becomes very obvious, and the driving experience is not very good.

Is the gasoline in Zhangjiakou ethanol gasoline?

Zhangjiakou gasoline is ethanol gasoline. Characteristics of ethanol gasoline: Ethanol has strong dissolving and cleaning properties. When vehicles use ethanol gasoline for the first time, especially after using 1 to 2 tanks of fuel, the cleaning effect of ethanol will soften and dissolve various impurities deposited and accumulated in the fuel tank and fuel lines, such as rust, dirt, and colloidal particles, mixing them into the fuel and causing poor fuel flow. Check the fuel tank when using ethanol gasoline for the first time: Since ethanol gasoline is blended with a certain amount of denatured fuel ethanol, and ethanol is a hydrophilic liquid that easily mixes with water, water can accumulate at the bottom of the fuel tank. Therefore, when using ethanol gasoline for the first time, the fuel tank should be inspected to prevent the ethanol gasoline from mixing with any possible accumulated water at the bottom of the tank, which could lead to excessive water content in the fuel and affect the normal operation of the engine.
