The installation position for ETC in small cars is generally in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed in the lower middle part. The suitable installation position should be at a height of no less than 1.2 meters and no more than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave skylight zone. ETC stands for Electronic Toll Collection, meaning electronic toll collection system. To apply for ETC, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle registration certificate. If the application is handled by a non-owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. Documents required for company vehicles: Introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle registration certificate; the vehicle that needs to apply for ETC. Here are some precautions for installing ETC: Do not block the driver's view. It is best to install it behind the rearview mirror: Many car models have a large tilt angle of the windshield, which reduces the driver's field of vision. If this is not considered during ETC installation, it may increase the driver's blind spot. Install it on the right side behind the rearview mirror to avoid blocking the view. Do not affect charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Do not remove the ETC randomly once installed: The button in the middle of the adhesive is an anti-tamper rod connected to a switch. After installation, the windshield will press the anti-tamper rod in. If the ETC is removed, the rod will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will need to visit an ETC service point to unlock it. This feature is designed to prevent multiple vehicles from sharing one device. Precautions for using ETC: The ETC transaction sensing range is 8 meters. To avoid paying for the vehicle in front due to its ETC device malfunction, maintain a distance of more than 10 meters from the vehicle ahead. The ETC lane recognizes vehicles at a speed of 20 km/h; driving too fast may result in failed toll deduction. When using a debit card for ETC, insufficient balance will also cause toll deduction failure.

What maintenance items are required for the third car service?

The maintenance items required for the third car service are as follows: 1. Replace the engine oil and oil filter. If the oil and filter are not replaced in time, the oil will deteriorate over time, which can easily lead to severe wear in the engine and other parts. Whether it's a new car or an older car that has been used for several years, regular maintenance of the engine oil and oil filter is required every 10,000 kilometers. 2. Clean or replace the air filter. If the car is driven for a long time in areas with a lot of dust, the replacement interval for the air filter should be shortened. For vehicles driven under normal conditions, the air filter should be replaced approximately every 10,000 kilometers. 3. Check the brake pads. Checking the brake pads is an essential item, especially after every 10,000 kilometers of driving. The brake pads will inevitably experience some wear, and their thickness will naturally decrease. Moreover, brake pads have a certain service life, and regular checks can ensure the safety of the driver.

How many kilometers can a BMW X2 drive after the oil warning light comes on?

It is best to stop the BMW X2 immediately when the oil warning light comes on, as it indicates a severe shortage of engine oil. Below are detailed explanations: Consequences of the oil warning light: The oil warning light indicates insufficient oil, which can lead to dry friction in certain moving parts. Dry friction causes rapid wear of mechanical components, potentially resulting in the vehicle being completely scrapped. Reasons for the oil warning light: Insufficient oil level reduces the oil pump's output or prevents it from pumping oil due to air intake, leading to a drop in oil pressure. High engine temperatures can thin the oil, causing it to leak excessively through gaps and resulting in low oil pressure. Damage or excessive wear and assembly gaps in oil pump components can also cause the pump to fail or deliver insufficient oil.

How to Solve Abnormal Noise from Car Fuel Pump?

Solutions for abnormal noise from the car fuel pump are as follows: 1. First, check if the gasoline filter is clogged and measure the fuel pressure. If the noise is caused by a clogged gasoline filter, simply clean and unclog the filter. 2. If the abnormal noise is due to a damaged fuel pump, it is best to replace it with a new one and have it repaired at a professional auto repair shop. Here are the signs of a damaged car fuel pump: 1. Difficulty starting the car. If the car fails to start after several attempts, the fuel pump may already have issues; when the pump core is damaged, there will be no sound of the fuel pump operating when the fuel supply system is activated upon turning the key. 2. Abnormal noises from the car. While driving, if you hear sounds like flowing water, grinding, whistling, or buzzing, these are warnings of fuel pump failure. 3. Engine vibration. Normally, engine vibration is very regular and smooth. If you can clearly feel increased engine vibration, it should be inspected. 4. The engine warning light turns on. The fuel pump is part of the car's fuel tank, specifically designed to draw gasoline from the tank and deliver it to the engine. If the fuel pump malfunctions, gasoline cannot be transported to the engine, and the light indicates an abnormality.

What Causes Slow Engine Temperature Rise?

Slow engine temperature rise may be caused by a faulty temperature sensor. Related explanations are as follows: 1. During winter, slow temperature rise could be due to a stuck thermostat. A stuck thermostat can cause the engine to operate in an abnormal cycle, preventing rapid temperature increase. If the thermostat has been replaced before, the new thermostat might have a lower opening temperature, initiating the large circulation before the temperature rises sufficiently, which affects the warming process. 2. It could also be that the thermostat is continuously in large circulation mode, resulting in slower temperature rise. The performance of the thermostat also affects the speed of temperature increase. In a cold engine state, the small circulation through the heater core should take priority, and the large circulation should only open after the temperature has risen.

What is the fuel consumption of the CFMoto NK400?

The fuel consumption of the CFMoto NK400 is approximately 4.5L/100Km. The following are the factors affecting fuel consumption: Vehicle factors: Fuel consumption is related to displacement. Generally, the larger the displacement, the higher the fuel consumption. At the same time, the thermal efficiency of the engine and the design of the motorcycle's shape will also affect the vehicle's fuel consumption. External environmental factors: Road conditions and the external environment can also have a significant impact on fuel consumption. Generally, flat roads are more fuel-efficient than rough roads, straight roads are more fuel-efficient than winding roads, and smooth traffic is more fuel-efficient than traffic jams. In winter, the low temperature prevents gasoline from reaching the optimal combustion temperature, leading to incomplete combustion and resulting in additional fuel consumption.

What Causes the Car Wiper Not to Spray Water?

Car wiper not spraying water can be caused by the following reasons: 1. Clogged pipes. If you often drive on unpaved roads, tiny dust particles can enter the wiper's spray nozzles. Over time, the dust can block the small spray nozzles, preventing the wiper from spraying water. The solution to this problem is simple: just insert a small brush into the wiper's spray nozzle to clean out the dust or dirt attached to it. While cleaning, turn on the wiper's spray switch, and the wiper will gradually start spraying water. 2. Too little or no water in the windshield washer fluid container can cause the wiper not to spray water. You should regularly check the remaining amount of washer fluid and replenish it in time. The windshield washer fluid container for the wiper is designed in the engine compartment of the car, and some models can display the remaining water level on the dashboard.
