Can the ETC device be placed on the tinted black area?

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 detect the toll station's scanning equipment. However, installing them outside the black dotted area has drawbacks, such as reduced solar charging capability, which may lead to power depletion over time. Correct installation positions for ETC: For small vehicles like cars and vans, the ETC card and OBU device should be installed on the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is on the lower middle part. ETC installation requirements: height should be no less than 1.2 meters and no more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the electronic tag surface 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; a red light will briefly turn on, and the OLED screen will display "Tag Invalid" or "Insert Card," indicating the device is functioning properly. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and attach 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.

Is power steering fluid the same as hydraulic transmission fluid?

Power steering fluid and hydraulic transmission fluid are the same. Introduction to power steering fluid: Power steering fluid is a type of transmission fluid, and a crucial indicator is its low-temperature fluidity. Even when temperatures drop to several dozen degrees below zero, it does not thicken, ensuring smooth control of the steering system. Usage method: Start the car and use an oil extractor to remove all the old fluid. Inject new power steering fluid, then turn the steering wheel back and forth to allow the new fluid to circulate. For thorough circulation, it is best for the driver to turn the steering wheel fully left and right, then make slight left and right turns. The purpose of turning the steering wheel back and forth is to expel the old fluid from the steering system, but avoid holding the steering wheel at full lock for extended periods, as this can cause excessive oil pressure and lead to the power steering fluid being ejected.

What is a Flood-Damaged Vehicle?

Flood-damaged vehicles refer to cars that have been submerged in water and subsequently sold to used car markets across China through certain channels. One-time hardware damage in flood-damaged vehicles: Many electronic components are one-time use and cannot be opened. Although they may appear fine during repairs, various issues are bound to arise during later use. The repair costs for such vehicles can be astonishingly high. Therefore, if your city frequently experiences natural disasters like droughts or floods, it is advisable for car owners to purchase relevant vehicle insurance. Low safety performance of flood-damaged vehicles: If a motor vehicle is submerged in water, it can easily lead to rusting of body components, shortening the vehicle's lifespan and reducing its safety performance. For example, water damage can cause corrosion and rusting of the vehicle's wiring, leading to sudden engine shutdowns or spontaneous combustion due to short circuits while driving, with potentially unimaginable consequences.

How Many Bottles of Undercoating Are Needed?

Undercoating generally requires five bottles. Application areas of undercoating: It can be sprayed on exposed parts of the vehicle such as the chassis, wheel hubs, fuel tank, lower body panels, and luggage compartment. After quick drying, it forms a firm and elastic protective layer that prevents impacts from flying stones and gravel, avoids moisture, acid rain, and salt from corroding the metal parts of the chassis, prevents rust and corrosion, and ensures the driving safety of the vehicle owner. Functions of undercoating: Undercoating effectively protects the chassis from road debris impacts and minor scrapes. It prevents corrosion from acids, alkalis, and salts on the chassis metal plates. It also prevents loosening of chassis screws, reduces noise transmission during driving, enhancing driving quietness. Additionally, it blocks heat conduction from the chassis metal plates, keeping the cabin warm in winter and cool in summer.

Should You Release Air from Tires with High Pressure in Summer?

If the tire pressure is indeed high in summer, exceeding the recommended value by more than 0.3 bar, it is advisable to slightly release some air from the tires. However, when doing so, ensure that the air is released evenly. Make sure the air pressure is balanced between the two front wheels and the two rear wheels. Avoid releasing air from only one side, as a significant difference in tire pressure between the two tires can cause the vehicle to pull to one side. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and pulling, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, and impacts can lead to internal cracks or blowouts, resulting in a flat tire.

What is the model number of the transmission fluid level screw?

The transmission filling screw is M20x1.5, and the drain screw and oil pan screw are of the same model, both being M14x1.5. The signs that indicate the need for transmission fluid replacement are: body shaking, gear shifting hesitation; the dashboard shows a transmission high-temperature warning; the car stalls; unusual noises occur. The methods for replacing transmission fluid are as follows: Unscrew the drain screw at the bottom of the transmission to drain the fluid before refilling. Remove the transmission oil pan directly to drain and refill the fluid: this method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to replace automatic transmission fluid: dynamic fluid replacement with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission. The hazards of not replacing transmission fluid for a long time: 1. Damage to the transmission's gear shifting control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affects the normal operation of the transmission, leading to damage to the transmission valve body.
