Method to turn off the Mercedes-Benz start-stop function: The start-stop function is enabled by default when the vehicle starts. Pressing the start-stop function button once can deactivate the automatic start-stop function. If you wish to use this function again, simply press the button to reactivate it. The icon for the automatic start-stop system switch is an 'a' enclosed within a circle. Taking the smart as an example, this vehicle is a microcar under the Mercedes-Benz brand, with dimensions of 2695 mm in length, 1663 mm in width, and 1555 mm in height, and a wheelbase of 1873 mm. In terms of suspension, the smart features a McPherson strut independent front suspension and a torsion beam non-independent rear suspension.

When driving a Mercedes-Benz, I find the start-stop function quite annoying at times, especially in traffic jams where the engine keeps turning on and off automatically, which can be dizzying. Turning it off is simple—just look for the button with an 'A' letter or the start-stop icon near the steering wheel or on the dashboard, and press it after starting the car. As a city driver, this one-minute operation avoids the discomfort caused by frequent vibrations. Mercedes-Benz designs it to be enabled by default, so you need to press the button every time you start the car, but it becomes convenient once you get used to it. On highways, I keep it on to save fuel, but in crowded urban areas, turning it off is more relaxing. Some newer Mercedes models also allow control via the central display screen, with a user-friendly and straightforward interface.

As someone with some knowledge about cars, the start-stop system is primarily for fuel efficiency and environmental protection, but its principle relies on the battery and starter to support engine stop-start cycles, which may increase wear with frequent operation. The deactivation process is straightforward: after starting the car, locate the prominently marked button and press it to disable the system. In most Mercedes-Benz models, this button is located in the center console area with clear labeling for easy identification. Personally, I recommend turning it off in urban congested traffic for a smoother drive and reduced startup noise disturbance. Long-term, Mercedes components are durable, so deactivation won't cause major issues, though fuel consumption may slightly increase by about 0.5%. Always confirm the button's location before operating to avoid distracted driving.

What is the HOLD light?

HOLD light is the gear lock indicator light. When the HOLD light is on, it indicates that the gear is locked in a specific position. When driving uphill or on icy/snowy roads that require low-gear operation, you can activate HOLD to lock the transmission in second gear. The button for this switch is located in the middle of the gear lever. Pressing it again will deactivate the function. Normally, it's not recommended to use this feature as it may harm the transmission. Automatic gear lock is a forced downshift key, used when gears get stuck or during towing. When HOLD is activated, the parking brake system will automatically engage each time the vehicle comes to a complete stop after braking. You'll feel a release of pressure on the brake pedal, at which point you can release the pedal without worrying about the vehicle rolling. Working principle of gear lock indicator light: The transmission control unit uses this sensor to detect the gear selected by the driver and performs corresponding control actions. Relationship between neutral switch and gear position switch: In older vehicles, the P (Park) and N (Neutral) switches were connected in series with the starter motor switch, meaning the engine could only be started in these two positions. In newer vehicles, the control unit identifies the neutral signal first, then decides whether to engage the starter motor.

What Causes Difficulty in Removing the Car Key?

Car key difficulty in removal can be attributed to the following reasons: 1. P gear not properly engaged: When exiting the vehicle, the gear was not shifted to P or the P gear did not fully engage, possibly obstructed by an object, thus failing to trigger the electronic sensor. 2. Steering wheel locked: The steering wheel was not returned to its proper position when parking, causing an abnormal lock. The solution is to insert the key, attempt to turn the steering wheel left and right while twisting the key, which will release the steering wheel lock. 3. Obstruction in the key slot: The solution involves removing the obstruction, starting the car, shifting the gear again to ensure it is fully engaged, after which the key can be removed.
