What to Do in Case of Illegal ETC Removal?

ETC is designed for dedicated use by default, and it comes with a protective device during installation—a push rod inside the adhesive position. Once the electronic tag is installed, it must not be removed without authorization. If removed, the anti-removal switch of the electronic tag will be triggered, causing the push rod to extend, rendering the ETC invalid. When passing through an ETC lane on the highway, it will display "OBU (On-Board Unit) illegally removed," preventing normal passage. Of course, some vehicle owners may not have removed the ETC card, but the detachment or loosening of the electronic tag may also trigger the anti-removal switch, leading to OBU failure. Reasons for the electronic tag becoming loose or detached include improper OBU installation, bumps or collisions while driving, excessive speed, or prolonged exposure to sunlight. If the OBU displays "illegally removed," don’t panic. The vehicle owner simply needs to visit an ETC customer service center or service outlet to have it reinstalled and reactivated. ETC users who enter the highway normally but receive prompts such as "illegal removal" or other abnormal messages may encounter the following issues: Before entering the toll station, ETC users should merge into the correct lane in advance and drive vertically into the ETC lane, keeping the speed below 20 km/h. Otherwise, the system may encounter errors while reading the tag. Improper use of the electronic tag can also lead to passage problems. If the ETC electronic tag becomes detached or loose due to personal movement or prolonged sun exposure, or if it is not properly affixed to the vehicle’s windshield, the tag may fail, preventing the system from automatically lifting the barrier. If the lane system displays a "U-turn" or "overtime vehicle" message, automatic deduction or card swiping for toll payment will not be possible, and the user must pay the toll in cash.

What Are the Reasons for Poor Car Cooling?

Poor car cooling can be caused by insufficient engine cooling, insufficient coolant in the radiator, or a faulty thermostat preventing the large circulation from opening. The reasons and solutions for poor car cooling are as follows: Insufficient engine cooling: Poor engine cooling can lead to excessively high water temperature in the radiator. Over time, scale buildup inside the radiator can thicken, impairing the radiator's ability to dissipate heat. When overheated water cannot release its heat, it may result in "boiling over." Additionally, clogged ventilation holes in the radiator are a common cause of poor cooling. Solution: Removing scale from the radiator can effectively improve cooling performance. Insufficient coolant in the radiator: Coolant serves as the heat carrier in the cooling circulation system, transferring engine heat away through the system. When coolant levels are low, the system's heat dissipation capacity decreases, preventing the engine temperature from dropping. Coolant loss is typically due to leaks or evaporation. Common causes of coolant leaks include damaged water pump seals, cracked pipes, loose connections, or radiator damage. Solution: If the coolant level is too low, it can be replenished by adding an appropriate concentration of antifreeze through the overflow tank. Faulty thermostat preventing large circulation from opening: A malfunctioning thermostat can disrupt cooling. The thermostat is located at the engine's water outlet and regulates cooling intensity. When the engine reaches a specified temperature, the thermostat opens the large circulation pathway. If the thermostat fails to open this pathway, it disrupts coolant circulation, leading to engine overheating. Solution: The thermostat is installed in the circulation pipeline between the radiator and the engine. If damaged, it should be replaced.

Are There Successful Cases of Vehicle Title Transfer on Maodou New Car Platform?

There are many successful cases of title transfer. If you want to transfer the title of a car purchased on Maodou New Car Platform with a 48-month installment plan, you need to wait until the lease term reaches 12 months and all payments are fully settled. Additionally, all traffic violations associated with the purchased vehicle must be resolved before the title transfer can proceed. For the transfer process, you will need to bring the purchase contract, the owner's ID card, driver's license, and other required documents, and follow the instructions provided by the customer service. More relevant information is as follows: 1. Introduction: Maodou New Car is a platform that adopts a "lease-to-own" car purchasing model. It is quite reputable and widely recognized. This "lease-to-own" approach can promote the development of the automotive industry and alleviate consumers' financial pressure when buying a car. It allows consumers to enjoy the use of a vehicle with a small initial payment, enabling more people to own a car. 2. Note: The "lease-to-own" model requires leasing the car first. The title transfer can only be processed after one year of leasing. During the leasing period, the ownership of the vehicle does not belong to the lessee but to Maodou New Car Platform Co., Ltd. Additionally, this "lease-to-own" model involves certain interest charges, so the total cost of the vehicle is often higher than purchasing the same model outright at a 4S dealership.

When to Turn on the Marker Lights While Driving?

Marker lights are warning lights on vehicles, primarily used in low visibility conditions (such as driving at night, during dusk, in rainy weather, or in hazy conditions) to alert other vehicles. Marker lights are the outermost lights located at the front and rear of the vehicle. Large trucks also have marker lights on their roofs and sides. Literally, 'marker' means warning, and 'light' refers to the outline, so marker lights serve as warning lights to alert other vehicles. They are installed along the edges of the vehicle's roof, indicating both the height and width of the vehicle.

Does Car Rain Repellent Damage Glass?

Car rain repellent does not damage glass. Below is an introduction to car rain repellent: 1. How car rain repellent works: Rainwater tends to remain on glass windows because glass is hydrophilic, and dust accumulated during driving makes it harder for raindrops to slide off. Car rain repellent adopts the bionic principle of lotus leaves, spraying fluorine nano-molecules on the glass surface to form a smooth waterproof film that quickly channels rainwater away, preventing blurred vision and ensuring safer driving. 2. How to use car rain repellent: (1) First, clean all dust and stains from the rearview mirror or car window glass, and dry it with a cloth. (2) Spray the rain repellent at close range and gently spread it evenly with a dust-free cloth. (3) Wipe off any traces of the rain repellent and then leave it in a cool place for two hours.
