Rear window defogging does not require turning on the air conditioning. Simply turn on the defrost (fog) switch and the air blower switch to direct airflow to the front windshield. Below is relevant information about car defogging: Defogging Button Symbols: The symbol for the front windshield defogging button is a fan shape with many curves. The symbol for the rear windshield defogging button is a square with many curves. Front windshield defogging uses the air conditioning, while rear windshield defogging uses electric heating wires.

What is the glass in front of the car called?

The glass in front of the car is called the windshield. Tempered glass is another type of safety glass, widely used in the side and rear windows of modern cars. Compared to laminated glass, tempered glass gains increased strength through heating and pressurization. When damaged, it shatters into smooth, small particles resembling breadcrumbs, thereby reducing the likelihood of injury from glass fragments. In fact, car owners can also choose to apply film to the glass for effective protection. However, the requirements for automotive glass film are relatively high, as the light transmittance of the front windshield must be greater than 70% to ensure driving safety is not compromised.

Why is the brake making a loud noise?

Brakes making loud noises are usually caused by rusted brake pads or excessive wear between the brake disc and brake pads. Braking is achieved through intense friction between the brake pads and the brake drum. A brake is a mechanical device used to slow down the speed of a vehicle, also known as a decelerator. The car's brake pedal is located below the steering wheel. Pressing the brake pedal activates the brake linkage, which applies pressure and transfers it to the brake pads on the brake drum, clamping the brake rotor and causing the car to slow down or stop. The manual brake in a car is located next to the gear shift and is connected to the brake lever. Common examples also include bicycle brakes, which use rod-shaped brakes fixed to the frame or disc brakes to slow down the vehicle.

What is the reason for the buzzing sound when stepping on the accelerator?

The reason for the buzzing sound when stepping on the accelerator is an inappropriate gear position, and it is necessary to downshift to increase speed. The accelerator, also known as the throttle or air valve, is a control device that regulates the engine's power (thrust). In piston-type aircraft engines, the throttle controls the opening of the carburetor's throttle valve to adjust the cylinder's filling volume, thereby determining the engine's output power. In gas turbine engines, the throttle regulates the metered fuel flow of the fuel regulator, thus determining the thrust generated by the engine. The throttle position is controlled by the pilot in the cockpit through the throttle lever, which is transmitted to the carburetor or fuel regulator on the engine via control system components such as pushrods, rocker arms, torque tubes, cables, pulleys, and sector gears.
