ETC devices can be installed on the black dotted area of the windshield, as long as they do not obstruct the driver's view and can sense the detection equipment of the toll station. However, installing them outside the black dotted area of the windshield has drawbacks, such as reduced solar charging capability of the ETC device, which may lead to power depletion over time. Correct installation position for ETC: For small vehicles like cars and vans, the ETC card and OBU device should be installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part. ETC installation position requirements: the height should not be less than 1.2 meters or more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane). The ETC installation process is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly turn on. The OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning normally. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then, peel off the adhesive backing film of the OBU and attach it to the installation position. Press firmly with your hand for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield, ensuring the chip is properly inserted into the OBU device.

What Does Used Car Mean?

Used cars refer to vehicles that are not brand new from the manufacturer but have been previously owned and used for a period of time. Due to their affordable prices and strong liquidity, used cars have become an integral part of the automotive market. The used car transaction tax invoice is regulated by the state. When conducting a used car transaction, the operator of the used car trading market must issue a unified invoice supervised by the tax authority to the buyer as proof for the transfer registration of the used car. Below is a detailed introduction about used cars: Definition of Used Cars: Used cars typically refer to motor vehicles that can still be used before reaching the national scrapping standards. There are many advantages to purchasing used cars, including cost-effectiveness, low depreciation rates, and easy availability of parts. Consumers can buy a higher-grade used car for the price of a new one, and the same brand and model can often be purchased at a lower cost. Low Depreciation Rate: After a car is registered and licensed, its value decreases every year. However, used cars have a lower depreciation rate, so selling a used car after several years of use won't result in significant losses. Additionally, the automotive service industry for used cars is well-developed, and related car parts are generally abundant.

What are the criteria for determining accidents in the 'return one and compensate three' policy for used cars?

According to the requirements of the 'Used Car Circulation Management Measures,' the conditions for returning a used car must involve the seller's concealment and fraud that prevents the transfer registration from being processed. The seller's concealment of facts generally refers to issues such as the car having been in an accident, water damage, fire damage, problems with documentation, or unclear ownership. Additionally, clear evidence is required to return the car. Here is some relevant information about used cars: Introduction: A used car refers to a motor vehicle that has been registered with the public security traffic management authorities, has not yet reached the national scrapping standards or is within its economic service life, and can still be used. Precautions: When buying a used car, you should carefully observe aspects such as the car's manufacturing date, actual mileage, whether it has been involved in a major accident, and whether the previous owner maintained the vehicle properly.

What does it mean when a used car is only sold locally?

To prevent vicious competition among 4S stores in different regions, the state has strictly stipulated restrictions on sales areas. 'Used cars only sold locally' means that consumers who purchase vehicles from this dealer must register and license the car in the same city. Below are some precautions for buying used cars: Carefully inspect the body: Check if the body has been damaged in a collision. Stand at one corner of the front of the car and look towards the rear, observing the seams of the body. If they are not straight, the gaps vary in size, the lines are curved, or the decorative strips are falling off or appear mismatched, it may indicate that the car has been in an accident or undergone repairs. Carefully inspect the interior: Worn pedal mats, very dirty seats, and worn door handles all suggest that the car has traveled a considerable distance. If the seller provides seat covers, be sure to check the original seat cushions.

How Long is the Warranty for Used Cars?

Below is the warranty period for used cars of different ages: Young used cars: Also commonly referred to as nearly-new cars, these are typically 1-2 years old. The mileage of such used cars generally does not exceed 60,000 kilometers, and the vehicles themselves are relatively new. The advantage of buying this type of car is that it is still within the original manufacturer's warranty period, allowing you to continue enjoying free factory warranty for some time in the future. Youthful used cars: Generally, these cars are 3-6 years old, with mileage not exceeding 120,000 kilometers. These cars may have minor flaws, and due to the absence of original factory warranty, some wear and tear, and higher mileage, they are significantly cheaper than nearly-new cars. Middle-aged used cars: These are between 6-15 years old, with mileage around 300,000 kilometers. This category includes many classic and nostalgic models in the used car market, but they come without any warranty.

What does used car reconditioning mean?

Used car reconditioning means thoroughly inspecting a purchased used car for any issues and addressing them if found. Below is relevant information about buying used cars: Solutions for issues with used cars: According to Chinese used car laws, general used cars do not come with quality guarantees, but contracts must be signed during transactions. The contract must clearly describe any existing problems with the used car, such as if it has been in a major accident or is a repaired vehicle from a significant incident. If the seller conceals the true condition of the vehicle and fails to disclose it in the contract, the buyer can use the contract to resolve issues through market mediation. If the market does not intervene, arbitration or legal action can be pursued. Commercial insurance can help recover some losses through policy cancellation. Ways to purchase used cars: Used car trading markets offer the best hands-on experience. Online used car platforms provide the widest selection of vehicles. Personal sellers offer the most favorable prices.

Does the 2021 Tharu come with a particulate filter?

The 2021 Tharu is equipped with a particulate filter to meet the China VI emission standards. A particulate filter is a ceramic filter installed in the diesel engine's exhaust system that captures particulate emissions before they enter the atmosphere. It can reduce soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Diesel engine pollution mainly comes from three sources—particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Particulate emissions (soot) are mostly composed of tiny particles of carbon or carbide (smaller than 4-20μm). How the particulate filter works: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate filter through a dedicated pipe. After passing through the densely arranged bag-type filter inside, the carbon soot particles are adsorbed onto the filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites, burning off the adsorbed carbon soot particles and converting them into harmless carbon dioxide. To check whether the 2021 Tharu has a particulate filter, you can use the following three methods: Check the and to see if the particulate filter function is mentioned. Additionally, carefully review the fault codes in the manual to check for a "particulate filter" warning light indicator. Check the label on the oil filler cap. If the oil cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the three-way catalytic converter to see if there is a cylindrical section on the exhaust pipe. If present, that is the particulate filter.
