What does the rear button in the car mean?

rear literally means the rear or back. The Rear button in the car is the rear windshield defogger switch. Pressing it can remove the fog on the rear windshield. The rear button in the car is generally located in the air conditioning control panel. Here are some methods for defogging the rear windshield: 1. Open the windows for convection: You can open a gap in the windows on both sides, allowing the air inside and outside the car to form convection, reducing the temperature difference, and the fog will gradually disappear. 2. Use the air conditioning system: Simply select the appropriate gear of the air conditioning to use the wind blown by the air conditioning to defog. 3. Use professional defogging agents: Spray the defogging agent on the inner surface of the car glass, then wipe it clean. While removing dirt from the glass, it also forms a protective film to prevent water vapor from condensing into a fog layer on the glass.

What is a Vehicle PDI Inspection?

PDI (Pre-Delivery-Inspection) refers to the pre-sale inspection record of a vehicle. During the period from when a new car rolls off the production line until it is sold, various issues may arise. Therefore, a pre-sale inspection is conducted before delivering the car to the consumer to ensure the vehicle is problem-free. PDI is a mandatory inspection that new vehicles must pass before delivery. Below is an introduction to PDI inspection: 1. According to standard procedures, a PDI inspection form (Pre-Delivery Inspection Certificate) with at least 40 items must be completed during vehicle handover. Do not blindly sign the inspection form, as signing indicates the user's acceptance of the vehicle's condition at the time of sale. 2. PDI inspection includes checking various control module system data, fuel system, lighting system, braking system, air conditioning system, steering system, cooling system, inspecting wheels (including spare tire and tire pressure), battery and various fluid levels, engine compartment wiring harness, cleaning the engine compartment and body surface, and deactivating the vehicle transport mode, among others.

What are the reasons for high engine idle speed?

Reasons for high engine idle speed: 1. Idle control valve failure: The normal idle speed of an electronic fuel injection engine is determined by the idle control valve. The electronic control unit calculates signals such as engine speed, temperature, throttle switch, and air conditioning switch, then adjusts the idle control valve to open the intake bypass channel or directly increase the throttle opening to increase the intake air volume and raise the engine idle speed. If oil contamination or carbon deposits cause the idle control valve to stick or the throttle to fail to close properly, the electronic control unit cannot accurately adjust the engine idle speed. 2. Intake system leakage: Under normal circumstances, the intake air volume must be strictly limited. If there is a leak in the intake pipe, the air flow sensor cannot measure the actual intake air volume, leading to inaccurate control of the intake air volume by the electronic control unit and unstable engine idle speed. 3. Fuel injector leakage or blockage: If the fuel injector leaks or is blocked, it cannot spray fuel according to the instructions of the electronic control unit, resulting in a mixture that is too rich or too lean, causing poor operation of individual cylinders and unstable idle speed.

How to deal with dull and aging black car paint?

Methods to deal with dull and aging black car paint: Glaze sealing is an ideal way to handle dull and aging black car paint. The principle is to apply a glaze substance on the car body to fill the cracks in the paint, restoring its shine. You can also enhance the brightness of the paint by waxing or polishing. However, it should be noted that although these methods can improve the glossiness of the paint, they may damage the car paint to some extent. The following are the advantages of car glaze sealing: 1. The non-stick property of the glaze makes the paint surface less prone to dirt, keeping it clean. 2. After car glaze sealing, the glaze layer can increase the hardness and brightness of the paint surface, effectively protecting it from minor scratches and, to some extent, resisting the impact of temperature on the paint. 3. Glaze sealing has effects such as UV resistance, acid rain resistance, oxidation resistance, anti-static, anti-corrosion, and wash resistance. It can effectively reduce the roughness of the paint surface, minimize friction with the external environment, and better protect the paint surface.
