How to Use Mercedes-Benz Auto Start-Stop?

[DiAllison]

To turn off the default auto start-stop function in a Mercedes-Benz, simply press the start-stop function button. The auto start-stop system switch is marked with an 'A' inside a circle. To reactivate this function, press the button again. The working principle of the start-stop system is: when the vehicle stops moving due to traffic congestion or at an intersection, and the driver presses the brake pedal, the Star/Stop system automatically checks if the engine is idling without being in gear; the wheel speed sensors of the anti-lock system show zero; and the electronic battery sensor indicates sufficient energy for the next start. When these three conditions are met, the engine automatically stops. When the traffic light turns green, the driver presses the clutch, and the 'start stopper' can be activated to quickly start the engine. Auto start-stop should be turned off in the following situations: When driving on a steep slope, it's best not to use auto start-stop. Although the auto start-stop duration is brief, the engine's start-stop on a slope may lead to insufficient brake assistance. In extremely hot weather in southern regions when the air conditioning is running at full capacity, it's advisable to turn off the auto start-stop function. Since the air conditioning requires significant power consumption, the vehicle's electrical system may not provide enough power to run the air conditioning when the engine is off, which could make passengers uncomfortable.
