Can ETC be installed without mounting it on the windshield?

ETC can be used without being stuck to the windshield. Installing ETC on the upper part of the windshield is to minimize obstruction of the driver's view and to ensure better recognition by the equipment at highway toll stations. If you don't want to install it on the windshield, try to place it in an open position where it can be seen through the windshield. For small cars, the ETC installation position is generally in the upper middle part of the front windshield, while for large vehicles like trucks and buses, the installation position is in the lower middle part. The appropriate installation position should be no lower than 1.2 meters and no higher 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 window strip. Here are the precautions for installing ETC: Do not block the view; it's best to install it behind the rearview mirror: Many car models have windshields with a large rearward tilt, which reduces the driver's field of vision. If ETC is installed without considering this, it can increase the driver's blind spots. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. Do not interfere with 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 that can charge itself. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After the electronic tag is installed, the windshield will press the anti-removal lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To prevent issues caused by the ETC device of the vehicle in front malfunctioning, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic payment for the preceding vehicle. The ETC lane recognition speed is 20 kilometers per hour; driving too fast may result in failure to read the vehicle's device information and failed deductions. When using a debit card linked to ETC, insufficient balance may also cause deduction failures.

What does the tire size 120/70-12 mean?

The tire size 120/70-12 indicates: 120 represents the tire section width in millimeters; 70 is the aspect ratio, which is the ratio of the tire sidewall height to the tire section width, with 70 representing 70%. Generally, tire aspect ratios range between 30% and 80%; 12 is the rim diameter in inches. In addition to the size, tires are marked with the following common data: Tire cord material: Represented by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, ZG for steel radial cord tires. Speed rating: Indicates the maximum speed a tire can carry a specified load under specified conditions. Letters A to Z represent certified speed ratings from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Indicates the rim size compatible with the tire for practical use. Related information Tire lifespan: The wear life of a tire is between 30,000 to 50,000 kilometers. If the tire has not reached the wear limit or mileage but has been in use for 5 years or has developed significant cracks on the sidewalls, it should be replaced. Tire material: The main component of a tire is rubber. The maximum storage and anti-aging time for rubber, from natural latex to EPDM and nitrile, does not exceed 10 years. The average lifespan of various rubber products in use is 3-5 years.

Does Banana Oil Damage Car Paint?

Banana oil damages car paint. Because banana oil is an extremely strong solvent, it can quickly dissolve organic substances, including paint, making it easy to wipe or wash off. Banana oil, also known as thinner, has a chemical composition of isoamyl acetate. Banana oil is highly volatile, flammable, explosive, and toxic, making it a hazardous material. Pure banana oil is a colorless, transparent liquid, slightly soluble in water but soluble in various organic solvents, primarily used as a solvent and thinner for spray paint. Below are some methods for protecting car paint: 1. Waxing: Waxing can be done directly or after polishing. Direct waxing involves cleaning the car body and applying wax directly to the clear coat layer on the surface of the paint, while polishing waxing requires using a polishing machine to polish the paint surface before applying wax. This method can instantly make the car shine. 2. Glazing: Due to the composition of the glaze, it is not resistant to acidic or alkaline cleaning and can be easily damaged. It typically lasts only 1 to 3 months, and glazing can harm the car paint, requiring reapplication every two to three months. 3. Crystal Coating: Crystal coating is a hard protective layer specifically designed for car paint, seats, interior and exterior trim, glass, tires, and other key areas. It comes in quick-drying and slow-drying types, mainly determined by its main components. 4. Film Application: Car coating is a highly protective measure that can brighten the paint surface while also providing multiple benefits such as resistance to acids and alkalis, high temperatures, strong waterproofing, oxidation resistance, and UV protection.

What is the wading depth of a sedan?

The maximum wading depth for a typical sedan is 200-300mm. The wading depth of a sedan is determined by the height of the vehicle's chassis, which is the ground clearance listed in the vehicle's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when driving through waterlogged roads. Therefore, in terms of safe wading depth, off-road vehicles and SUVs have obvious advantages. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a reference when passing through waterlogged roads. If the air intake is below the water level when a sedan is wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it can cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. The height of the air intake, and thus the maximum wading depth, can be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before wading, always turn off the auto start-stop function to prevent the vehicle from automatically restarting after stalling in water, which could cause severe engine damage due to water intake. Judge the underwater road conditions based on the passage of vehicles ahead and choose an appropriate entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration. On roads prone to water accumulation, observe warning water level markers, trees, or other reference objects like the wheels and doors of other vehicles to estimate the water depth before deciding whether to proceed. Know your vehicle's safe wading depth. If the water depth exceeds half the tire height or the engine's air intake, do not proceed and choose an alternative route instead.

What are the reasons why the Focus cannot shift gears?

The reasons why the Focus cannot shift gears are as follows: 1. No fuel: The fuel gauge shows below the red line, naturally making it impossible to start. 2. Dead battery: This may be caused by leaving the headlights on for too long or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also lead to vehicle circuit failures. Checking for a dead battery is simple—just press the horn to find out. 3. Incorrect gear position: When starting an automatic transmission vehicle, the gear must be in P or N position. If it is in R or D, the vehicle will not start. Some manual transmission vehicles may also fail to start if the clutch is not depressed. 4. No antifreeze added: Some owners add water or low-quality antifreeze, which can cause the entire cooling system to freeze in extremely cold winter conditions, leading to a cracked engine and preventing the water pump from functioning. This not only makes it impossible to start but also damages other engine components. 5. P-lock solenoid valve failure: For safety reasons, to prevent accidental shifting into other gears when starting the vehicle, there is a P-lock solenoid valve that requires a signal from the brake pedal to release. These two components are interconnected, and if either one fails, the gear lever cannot be moved out of P position to shift into other gears. 6. Internal failure of the gear lever assembly: Wear and tear of the internal gears in the gear lever can cause it to get stuck, making it difficult to move forward or backward, resulting in an inability to shift gears or difficulty in shifting. 7. Incomplete clutch disengagement: This may be caused by faults in the clutch disc or pressure plate, generally requiring the replacement of the clutch three-piece set, which includes the friction disc, pressure plate, and release bearing.
