The correct way to use an exhaust brake: A regulating valve is installed on the engine exhaust pipe. By closing this valve, the pressure during the exhaust stroke is increased, and the resulting negative pressure is utilized to obtain braking force. Below are the precautions for using an exhaust brake: 1. Throttle at zero: When the exhaust brake is in use, the accelerator pedal should be at the zero position, and the fuel injector stops injecting fuel. If the accelerator pedal or clutch pedal is pressed, the exhaust brake will automatically shut off, preventing engine stalling when stopping and exhaust brake activation during fuel injection. 2. Prohibited in poor road conditions: It is best not to use the exhaust brake on icy, snowy, or slippery roads, as there is a risk of driving wheel slip and skidding.

Does the Mercedes-Benz C-Class have Burmester sound system?

Mercedes-Benz C-Class comes with Burmester sound system. Burmester sound system effects: The front sound field's tweeters are upgraded with 3D rotating tweeters. In addition to the stunning acoustic configuration, the visual effects are equally impressive: when the system starts, the two tweeters installed in the door mirror triangle panels will light up together with the ambient lighting of the same color, while rotating outward by 10mm to the optimal position to provide the best high-frequency listening experience. Configuration: Although the Mercedes-Benz C-Class and Mercedes-Benz GLC also offer the optional Burmester sound system, they do not come with the original 3D rotating tweeters. The 3D rotating tweeters are part of the full 24-speaker 3D Burmester system equipped on the Maybach 600. When music is played, the tweeters extend and rotate, changing color with the car's ambient lighting. The high notes are crystal clear, and the effect is significantly different compared to the original car's tweeters, truly worthy of the 3D version Burmester sound system.

Where is the electronic handbrake of Mercedes-Benz C200?

The handbrake of the Mercedes-Benz C200 is located below the left side of the dashboard. Electronic handbrake button: The electronic handbrake button of the Mercedes-Benz C200 Sport Edition is a metal switch marked with "(P)" located below the left side of the steering wheel. The Mercedes-Benz C200 Sport Edition is equipped with an automatic parking system. Simply press the brake pedal firmly, and you will see "HOLD" displayed on the center console, indicating that the automatic parking system is activated. Electronic handbrake: It works by pressing a button to connect the power supply, which then drives an electric motor to pull the brake pads, thereby locking the brake disc. Structurally, the electronic handbrake is indeed more complex than the mechanical handbrake, so its cost is also higher. In terms of design, the electronic handbrake is more aesthetically pleasing, takes up less space, and has a more compact and technologically advanced appearance. Some models' electronic parking brakes can automatically release when the accelerator is pressed, preventing issues with the braking system caused by driving with the handbrake engaged. Additionally, the space saved by eliminating the traditional handbrake lever can be designed for storage compartments or other purposes.
