Why does the Jetta's dashboard stay lit after the engine is turned off?

The reason why the Jetta's dashboard stays lit after the engine is turned off is that the car's power supply has not been turned off. Introduction to the Dashboard: The car dashboard is a device that reflects the working conditions of various vehicle systems. Different cars have different dashboards. However, conventional dashboards in general cars include the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc. Beneath the surface of modern car dashboards, various indicator lights or warning lights are installed, such as the coolant level warning light, fuel level indicator, washer fluid level indicator, charging indicator, high/low beam indicator, transmission gear indicator, anti-lock braking system (ABS) indicator, traction control indicator, airbag (SRS) warning light, etc. Dashboard Classification: Conventional pointer-type dashboards, pointer-type dashboards paired with onboard computers, pointer-type dashboards matched with LCD displays, and full LCD displays. Yellow lights are fault indicators: When a yellow light on the dashboard illuminates, it informs the driver that a certain system function of the vehicle has been lost. For example, if the ABS warning light comes on, the direct implication is that the ABS is no longer functioning, which may cause the wheels to lock up during braking.

What is the reading method of a cylinder gauge?

Taking the cylinder gauge as an example, the mnemonic for its reading method is 'add clockwise, subtract counterclockwise': (1) When the pointer's index rotates clockwise, the reading should be added to the original zero calibration base. (2) When the pointer's index rotates counterclockwise, the reading should be subtracted from the original zero calibration base. Here is more information about the cylinder gauge: 1. Precautions: The default cylinder diameter can only increase; do not observe the changes of the small pointer. If the extension rod is too long, the cylinder gauge may get stuck in the cylinder and cannot measure; or if it is too short, the movable measuring head may not contact the cylinder wall at all, causing the dial indicator to remain stationary and unable to measure. 2. Brief description: The internal dial gauge, also known as the cylinder gauge, is a comparative measuring tool used for measuring bore diameters.

Where is WM Motor from?

What are the classifications of the running system?

The running system is divided into four main parts: axles, wheels, frame, and suspension. Here is a related introduction about the functions of the running system: 1. Frame: Install the various assemblies and components of the car, maintain the correct relative positions, and bear various static and dynamic loads from the vehicle and the ground. 2. Axle: Transmit the forces in all directions between the frame or the load-bearing body and the wheels. 3. Wheels: Support the total mass of the car and cargo; ensure the adhesion between the wheels and the road surface to improve the traction, braking, and off-road capability of the car; together with the car suspension, reduce the impact during driving and mitigate the resulting vibrations to ensure good ride comfort and smoothness of the car.

Where is the car's spark plug located?

The car's spark plug is located under the hood. Here is an introduction to spark plugs: 1. Function of spark plugs: They introduce high-voltage electricity into the combustion chamber and cause it to jump across the electrode gap to produce a spark, thereby igniting the combustible mixture in the cylinder. 2. Composition of spark plugs: They mainly consist of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell, with the side electrode welded to the shell. 3. Standard spark plugs: The insulator skirt is slightly recessed into the shell end face, and the side electrode is outside the shell end face. This is the most widely used type. 4. Projected insulator spark plugs: The insulator skirt is longer and protrudes beyond the shell end face. They have advantages such as high heat absorption and good anti-fouling performance, and they can be directly cooled by incoming air to lower temperature, making them less likely to cause hot spots. Therefore, they have a wide thermal adaptability range.

Can Windshield Washer Fluid Be Mixed?

Windshield washer fluid can be mixed with water, but purified water should be used. Tap water contains many impurities that can adhere to rubber hoses and affect normal spraying. Here is more information about windshield washer fluid usage: 1. Effects: Long-term use may increase friction between the glass surface and the wiper, causing scratches on the glass. 2. Performance: Anti-fog performance: Forms a single-molecule protective layer on the glass surface; Anti-static performance: Eliminates static charges on the glass surface; Lubrication performance: Reduces friction between the wiper and the glass, preventing scratches; Anti-corrosion performance: Has no corrosive effect on any metal.
