Heating wires are highly likely to be damaged, but using the correct method to replace the car film will not harm the rear window heating wires. During the replacement process, technicians use a heat gun to warm the film, ensuring it separates from the glass so the old film can be peeled off. If the heating wires are already broken, they cannot be repaired. Even a slight break in the rear window heating wires renders them ineffective, as it disrupts the heating function of the rear window glass. A break in the wires interrupts the circuit, and there is no way to fix them once they are damaged. While this does not affect the overall vehicle, it means you won't be able to clear fog from the window. If the wires break, the entire rear window glass must be replaced because the heating wires are installed during manufacturing and are very fragile. Although they are rarely used throughout the year, if they break, they should not be used or repaired—simply replace the glass.

Is it necessary to use Honda fuel additive for Civic?

Civic can use fuel additive, but it is not necessary to use fuel additive. The following is the specific content about Civic: Model: Civic is a turbo model, not suitable for taxi or ride-hailing services like Didi. Occasional use is acceptable, but frequent use is not cost-effective. The turbo needs to be replaced after approximately 100,000 to 150,000 kilometers, with high depreciation costs. Maintenance: Maintenance costs are relatively high, and fuel consumption is also high, especially in urban areas. If combined with harsh working conditions, it will significantly reduce the lifespan of the turbo engine. Development: Civic is a car under Honda, featuring a layered exterior design, exquisite interior, good spatial design, and high safety. The first-generation Civic was introduced on July 11, 1972, and over the decades, Civic has continuously innovated. It has become increasingly modern and technological, loved and accepted by more and more consumers.

What brand is the original audio system in the Audi S4?

Audi S4 premium audio experience upgraded with the original German B&O audio system. Here are the specific details about the Audi S4 audio system: Output power: Most current head units indicate music power, typically between 40W~60W, and the power should not be too high. Frequency response: The human ear can hear frequencies ranging from 20Hz~20KHz, so this specification should at least cover this range, and the wider the better. Signal-to-noise ratio: This refers to the ratio of music signal to noise. High-end car audio systems generally have a ratio above 90DB, and the higher this value, the better. Total harmonic distortion (THD): This indicator reflects the fidelity of sound reproduction. The lower the value, the higher the fidelity, and the better the audio performance.

Will the relay still conduct electricity if it's broken?

If the relay coil is broken or the contacts cannot touch, it will not conduct electricity. If the relay is short-circuited, it will still conduct electricity and remain continuously powered. The static contact that remains open when the relay coil is not energized is called a "normally open contact"; the static contact that remains closed is called a "normally closed contact". Below is an introduction to relays: A relay (Relay), also known as an electric relay, is an electronic control device. It consists of a control system (also called the input circuit) and a controlled system (also called the output circuit). Relays are generally used in automatic control circuit systems. Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current. In circuits, relays play roles such as automatic regulation, safety protection, and circuit switching.

What is the front vehicle assist alert in Lavida Plus?

Lavida Plus's front assist system is also known as the pre-collision safety system. Here are the specific details of the front vehicle assist alert in Lavida Plus: Identifying potential accidents: It can monitor the distance to the vehicle ahead in real-time. If the distance exceeds the safe range and a potential collision is detected, it will issue a warning to prompt the driver to take necessary action. Mitigating accident consequences: If the driver fails to respond, the system will automatically apply the brakes. In the event of a collision, it can effectively reduce the severity of the accident. Functions of Lavida Plus's front assist system: Monitoring function: Real-time monitoring of the distance to the vehicle ahead via a radar sensor installed in the front radiator grille. Warning function: In emergency situations, it preconditions the brakes and alerts the driver through optical and acoustic warnings as well as brake vibrations to prompt appropriate action. Automatic deceleration function: If the driver's braking response is insufficient, the front assist system will generate the necessary braking pressure to avoid a collision. If the driver does not brake at all, the system will automatically decelerate the vehicle. Automatic emergency braking function: If the driver does not respond to these warnings, targeted braking will be automatically activated.

For the transmission, the 2.0T model still uses a 6AT transmission, while the 3.5L model is likely to adopt Toyota's latest 8AT transmission. 2. Engine oil level check: Park the vehicle on a level surface. Pull out the dipstick to check the oil level. If the oil level is between the (F) and (L) marks, it is within the normal range. If it is below the (L) mark, add the specified type of engine oil. The oil level after adding should not exceed the (F) mark.
