Why Does the Jetta Brake Squeak?

Can the horn sound become louder again after it gets smaller due to water ingress?

The horn sound can become louder again after it gets smaller due to water ingress. After water ingress, you can only try to repair it. You can use a hair dryer to heat the horn to evaporate the water inside. Once the water evaporates, the horn will recover. However, if the diaphragm of the horn itself is damaged due to water ingress, you can only replace it with a new one. The relevant introduction about car horns is as follows: Introduction 1: The horn is the audio signal device of the car. During the driving process, the driver can issue necessary audio signals as needed and according to regulations. Introduction 2: It warns pedestrians and attracts the attention of other vehicles to ensure traffic safety, and is also used to urge driving and transmit signals.

Is it harmful to drive 5 kilometers with the handbrake on?

Driving 5 kilometers with the handbrake on is harmful, as it can damage the handbrake system and also affect the tires. The following is a related introduction to the handbrake: Introduction 1: The professional term for the handbrake is auxiliary brake, which differs in principle from the main brake. It uses a steel cable connected to the rear brake shoes to brake the vehicle. Introduction 2: Long-term use of the handbrake can cause plastic deformation of the steel cable. Since this deformation is irreversible, prolonged use will reduce its effectiveness and increase the handbrake's travel distance. Introduction 3: The handbrake system also includes a return spring. When the handbrake is engaged, the spring is stretched, and when released, it returns to its original length. Long-term use of the handbrake can also cause corresponding deformation in the spring.

What are the differences between aftermarket cruise control and OEM?

Navigation-equipped vehicle models are sometimes outsourced by the original manufacturer to aftermarket suppliers (the majority of cases), while others are produced in-house. These OEM suppliers also manufacture products for the aftermarket channel and supply some 4S stores. For instance, requirements for system stability, material selection, and prototype testing must adhere to original factory specifications. Specific differences are as follows: Cost variation: Due to differing requirements for prototypes, costs also vary. To ensure system stability, automakers generally avoid excessive fancy features, focusing only on essential modules. Reading vehicle data: Beyond quality control and functional differences, OEM products can access the vehicle's CANBUS data. Some suppliers have agreements with automakers to enable this data access, depending on how the infotainment manufacturer interfaces with the automaker. Same manufacturer, different quality: Products from the same manufacturer may vary in functionality and performance depending on their intended market.

Do You Need to Turn on the Air Conditioning for Rearview Mirror Heating?

No, you do not need to turn on the air conditioning. Here are the details: Rearview mirror heating function: This refers to the ability of the rearview mirror to be heated by electric heating wires embedded behind the mirror when driving in rainy, snowy, or foggy weather, ensuring the mirror surface remains clear. Benefits of the function: The rearview mirror heating is particularly useful during rainy or snowy days. When the heating is activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rain or fog from the mirror, eliminating the need for frequent manual wiping and thus reducing driving hazards. Working principle: An electric heating element (heating film) is installed inside the mirror of both rearview mirrors. In rainy or snowy weather, when the driver activates the rearview mirror heating function, the heating element quickly warms up to a fixed temperature within a few minutes, typically between 35-60 degrees Celsius, thereby heating the mirror and effectively removing fog and frost.

What is the difference between an auto trade invoice and a 4S store invoice?

There is essentially no difference between an auto trade invoice and a 4S store invoice; the only distinction lies in the issuing company. Below are the documents that car owners need to check when picking up their vehicle: 1. Purchase Invoice: The purchase invoice is not only required for vehicle registration but also for insurance, vehicle inspection, and transfer of ownership. It should be obtained when picking up the car and kept safe during use to avoid loss. 2. Vehicle Registration Certificate: Also known as the 'green book,' the vehicle registration certificate is generally not needed in daily use but is indispensable when transferring ownership. If the car is purchased with a loan, the green book is usually held by the bank or the 4S store. After the loan is fully repaid, it must be released and retrieved. 3. Warranty Service Card: The warranty service card covers free repairs for faults and damages caused by quality issues within a certain period or mileage, typically three years or 100,000 kilometers. 4. Vehicle Maintenance Manual: The vehicle maintenance manual should be carried with the car at all times. It serves as a reference for any uncertainties and helps avoid confusion when encountering car abnormalities.
