Why does the ETC device prompt 'Label Removed'?

1 Answers

ETC displays 'Label Invalid' due to unauthorized removal or relocation of the OBU device, or detachment/loosening of the ETC electronic tag. It needs to be reinstalled and reactivated at the original processing point or any highway ETC service center. 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-removal button on the back of the OBU; a red light will briefly turn on, and the OLED screen will display 'Label 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 of the OBU and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device. ETC activation method: Insert and remove the ETC card twice consecutively until the electronic tag screen displays 'Bluetooth On.' If 'Label Invalid' appears when inserting/removing twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth and open the corresponding mobile app (usually with a download QR code on the electronic tag), then enter the device activation interface. Click 'Device Connection' and wait patiently for the 'Connection Successful' prompt. After successful connection, upload a photo of the vehicle's front to complete activation.

How often should Fabia tires be replaced?

Fabia tires need to be replaced every 5 years. The longer the tires are used, the higher the risk of tread deformation and blowouts. To extend the service life of the tires, you can rotate the tire positions every 10,000 to 20,000 kilometers. Below is some relevant information about tires: 1. Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. They are usually installed on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance. 2. Tires are often used under complex and demanding conditions. During driving, they endure various deformations, loads, forces, and high and low temperatures. Therefore, they must have high load-bearing capacity, traction performance, and cushioning performance.

What does the 10w40 oil grade mean?

Oil grade 10w40 refers to the viscosity of the oil being 10w40. The number before the 'w' represents the cold-start performance, with smaller numbers indicating easier engine starts in cold weather. Common grades include 0W, 5W, 10W, and 15W. The number 40 indicates the oil's viscosity characteristics at high temperatures, where higher viscosity oils may be more suitable for high-speed driving or heavy-duty vehicles. Relevant information about engine oil is as follows: 1. Engine oil, also known as motor lubricant, serves to lubricate and reduce friction in the engine, assist in cooling, prevent rust and corrosion, and provide shock absorption. 2. Engine oil consists of two parts: base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives compensate for and improve any performance deficiencies.

How to Identify Fake 95 Octane Gasoline?

Methods to identify fake 95 octane gasoline are as follows: 1. Water adulteration in gasoline: "Water-adulterated gasoline" refers to gasoline with water content exceeding national standards. According to industry standards for gas stations, the water level in fuel tanks should not exceed 5mm. Since gasoline and water are immiscible, this doesn't normally affect engine combustion. However, some unscrupulous merchants physically or chemically blend water into high-grade gasoline to reap excessive profits. While such micro-emulsified gasoline won't cause immediate severe damage to engines or fuel systems, prolonged use of inferior products will accelerate wear on fuel pumps, filters, injectors, and even the engine itself. Impurities may clog fuel lines, preventing vehicle startup, while excessive water separation can corrode metal components (like pump bearings). Genuine gasoline appears light yellow, clear and transparent with a strong but not pungent odor, whereas watered-down gasoline has weaker smell and overly pale color. 2. Excessive gum content: Gasoline with high gum content appears darker, orange-red in color. Known as "dirty fuel," it easily causes fuel filter/injector clogging and poor atomization. Long-term use promotes carbon deposits on valves and combustion chambers, impairing engine performance. Qualified unleaded gasoline should be light yellow or pale red - deep red and cloudy appearance indicates inferior quality. Similarly, standard diesel should be transparent amber; darker shades suggest quality issues. 3. Gasoline with excessive mechanical impurities: These refer to all insoluble particulate matter (sand, clay, iron filings, etc.) suspended in fuel. Contaminated gasoline appears murky. Consumers can perform a simple test by dropping fuel onto A4 paper - genuine gasoline spreads evenly in circular patterns with transparent coloring and non-irritating odor. Inferior fuel leaves black/dark yellow residues at edges with visible particles and typically emits strong pungent smells.

What do 94V and 94H tires mean?

94V and 94H represent the load index and speed rating of a tire. A 94V tire means the maximum load capacity is 670KG, and the maximum speed is 240 kilometers per hour. The number 94 is the load index, corresponding to a maximum load of 670KG per tire, while V indicates the speed rating. Tire size classifications: 1. Full-size spare tire: A full-size spare tire has the exact same specifications as the other four tires on the vehicle and can replace any temporarily or permanently unusable tire. 2. Compact spare tire: This type of spare tire has a slightly smaller diameter and width compared to the other four tires, making it suitable only for temporary use. It should only be installed on non-driving wheels and must not exceed a speed of 80km/h.

Where is the jack placed in the Prado?

The jack in the Prado is located on the left side of the trunk. You can find it by prying open a square plastic cover about 15 cm in size. A jack is a lightweight lifting device that uses a rigid lifting component as its working mechanism, capable of elevating heavy objects within its stroke range via a top saddle or bottom claw. It is primarily used in factories, mines, and transportation sectors for vehicle repairs and other lifting or supporting tasks. Here is more information about jacks: 1. Jacks are compact, sturdy, and reliable, easily carried and operated by a single person. 2. There are two common types of vehicle jacks: rack jacks and screw jacks. 3. Their small size and space-saving design make them ideal for storage in the trunk, which is a shared characteristic of most jacks.
